<summary>Why?</summary>
|
||||
We are shipping both ESM and CJS module, and compatible with Vercel Edge, Cloudflare Workers, and other serverless platforms.
|
||||
|
||||
So we are using [conditional exports](https://nodejs.org/api/packages.html#conditional-exports) to support all environments.
|
||||
|
||||
This is a kind of modern way of shipping packages, but might cause TypeScript type check to fail because of legacy module resolution.
|
||||
|
||||
Imaging you put output file into `/dist/openai.js` but you are importing `llamaindex/openai` in your code, and set `package.json` like this:
|
||||
|
||||
```json
|
||||
{
|
||||
"exports": {
|
||||
"./openai": "./dist/openai.js"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
In old module resolution, TypeScript will not be able to find the module because it is not follow the file structure, even you run `node index.js` successfully. (on Node.js >=16)

||||

||||

By comparing the similarity of embeddings, we can derive an understanding of the similarity of two pieces of data. One use case is to compare the embedding of a question with the embeddings of our Nodes to see which Nodes may contain the data needed to answer that quesiton. Because the default service context is OpenAI, the default embedding is `OpenAIEmbedding`.

# Loader
|
||||
|
||||
Before you can start indexing your documents, you need to load them into memory.
|
||||
|
||||
### SimpleDirectoryReader
|
||||
|
||||
[](https://stackblitz.com/github/run-llama/LlamaIndexTS/tree/main/examples/readers?file=src/simple-directory-reader.ts&title=Simple%20Directory%20Reader)
|
||||
|
||||
LlamaIndex.TS supports easy loading of files from folders using the `SimpleDirectoryReader` class.
|
||||
|
||||
It is a simple reader that reads all files from a directory and its subdirectories.
|
||||
|
||||
<CodeBlock language="ts">{CodeSource}</CodeBlock>
|
||||
|
||||
Currently, it supports reading `.txt`, `.pdf`, `.csv`, `.md`, `.docx`, `.htm`, `.html`, `.jpg`, `.jpeg`, `.png` and `.gif` files, but support for other file types is planned.
|
||||
|
||||
You can override the default reader for all file types, inlcuding unsupported ones, with the `overrideReader` option.
|
||||
Additionally, you can override the default reader for specific file types or add support for additional file types with the `fileExtToReader` option.
|
||||
Also, you can provide a `defaultReader` as a fallback for files with unsupported extensions. By default it is `TextFileReader`.
|
||||
|
||||
SimpleDirectoryReader supports up to 9 concurrent requests. Use the `numWorkers` option to set the number of concurrent requests. By default it runs in sequential mode, i.e. set to 1.

### LlamaParse
|
||||
|
||||
LlamaParse is an API created by LlamaIndex to efficiently parse files, e.g. it's great at converting PDF tables into markdown.
|
||||
|
||||
To use it, first login and get an API key from https://cloud.llamaindex.ai. Make sure to store the key as `apiKey` parameter or in the environment variable `LLAMA_CLOUD_API_KEY`.
|
||||
|
||||
Then, you can use the `LlamaParseReader` class to local files and convert them into a parsed document that can be used by LlamaIndex.
|
||||
See [LlamaParseReader.ts](https://github.com/run-llama/LlamaIndexTS/blob/main/packages/core/src/readers/LlamaParseReader.ts#L6) for a list of supported file types:
|
||||
|
||||
<CodeBlock language="ts">{CodeSource3}</CodeBlock>
|
||||
|
||||
Additional options can be set with the `LlamaParseReader` constructor:
|
||||
|
||||
- `resultType` can be set to `markdown`, `text` or `.json`. Defaults to `text`
|
||||
- `language` primarly helps with OCR recognition. Defaults to `en`. See [../readers/type.ts](https://github.com/run-llama/LlamaIndexTS/blob/main/packages/core/src/readers/type.ts#L20) for a list of supported languages.
|
||||
- `parsingInstructions` can help with complicated document structures. See this [LlamaIndex Blog Post](https://www.llamaindex.ai/blog/launching-the-first-genai-native-document-parsing-platform) for an example.
|
||||
- `skipDiagonalText` set to true to ignore diagonal text.
|
||||
- `invalidateCache` set to true to ignore the LlamaCloud cache. All document are kept in cache for 48hours after the job was completed to avoid processing the same document twice. Can be useful for testing when trying to re-parse the same document with, e.g. different `parsingInstructions`.
|
||||
- `gpt4oMode` set to true to use GPT-4o to extract content.
|
||||
- `gpt4oApiKey` set the GPT-4o API key. Optional. Lowers the cost of parsing by using your own API key. Your OpenAI account will be charged. Can also be set in the environment variable `LLAMA_CLOUD_GPT4O_API_KEY`.
|
||||
- `numWorkers` as in the python version, is set in `SimpleDirectoryReader`. Default is 1.
|
||||

# DiscordReader
|
||||
|
||||
DiscordReader is a simple data loader that reads all messages in a given Discord channel and returns them as Document objects.
|
||||
It uses the [@discordjs/rest](https://github.com/discordjs/discord.js/tree/main/packages/rest) library to fetch the messages.
|
||||
|
||||
## Usage
|
||||
|
||||
First step is to create a Discord Application and generating a bot token [here](https://discord.com/developers/applications).
|
||||
In your Discord Application, go to the `OAuth2` tab and generate an invite URL by selecting `bot` and click `Read Messages/View Channels` as wells as `Read Message History`.
|
||||
This will invite the bot with the necessary permissions to read messages.
|
||||
Copy the URL in your browser and select the server you want your bot to join.
|
||||
|
||||
<CodeBlock language="ts">{CodeSource}</CodeBlock>
|
||||
|
||||
### Params
|
||||
|
||||
#### DiscordReader()
|
||||
|
||||
- `discordToken?`: The Discord bot token.
|
||||
- `requestHandler?`: Optionally provide a custom request function for edge environments, e.g. `fetch`. See discord.js for more info.
|
||||
|
||||
#### DiscordReader.loadData
|
||||
|
||||
- `channelIDs`: The ID(s) of discord channels as an array of strings.
|
||||
- `limit?`: Optionally limit the number of messages to read
|
||||
- `additionalInfo?`: An optional flag to include embedded messages and attachment urls in the document.
|
||||
- `oldestFirst?`: An optional flag to return the oldest messages first.

|
||||
|
||||
LlamaIndex.TS supports easy loading of files from folders using the `SimpleDirectoryReader` class.
|
||||
|
||||
It is a simple reader that reads all files from a directory and its subdirectories.
|
||||
|
||||
<CodeBlock language="ts">{CodeSource}</CodeBlock>
|
||||
|
||||
Currently, the following readers are mapped to specific file types:
|
||||
|
||||
- [TextFileReader](../../api/classes/TextFileReader.md): `.txt`
|
||||
- [PDFReader](../../api/classes/PDFReader.md): `.pdf`
|
||||
- [PapaCSVReader](../../api/classes/PapaCSVReader.md): `.csv`
|
||||
- [MarkdownReader](../../api/classes/MarkdownReader.md): `.md`
|
||||
- [DocxReader](../../api/classes/DocxReader.md): `.docx`
|
||||
- [HTMLReader](../../api/classes/HTMLReader.md): `.htm`, `.html`
|
||||
- [ImageReader](../../api/classes/ImageReader.md): `.jpg`, `.jpeg`, `.png`, `.gif`
|
||||
|
||||
You can modify the reader three different ways:
|
||||
|
||||
- `overrideReader` overrides the reader for all file types, including unsupported ones.
|
||||
- `fileExtToReader` maps a reader to a specific file type. Can override reader for existing file types or add support for new file types.
|
||||
- `defaultReader` sets a fallback reader for files with unsupported extensions. By default it is `TextFileReader`.
|
||||
|
||||
SimpleDirectoryReader supports up to 9 concurrent requests. Use the `numWorkers` option to set the number of concurrent requests. By default it runs in sequential mode, i.e. set to 1.

# JSONReader
|
||||
|
||||
A simple JSON data loader with various options.
|
||||
Either parses the entire string, cleaning it and treat each line as an embedding or performs a recursive depth-first traversal yielding JSON paths.
|
||||
Supports streaming of large JSON data using [@discoveryjs/json-ext](https://github.com/discoveryjs/json-ext)
|
||||
|
||||
## Usage
|
||||
|
||||
```ts
|
||||
import { JSONReader } from "llamaindex";
|
||||
|
||||
const file = "../../PATH/TO/FILE";
|
||||
const content = new TextEncoder().encode("JSON_CONTENT");
|
||||
|
||||
const reader = new JSONReader({ levelsBack: 0, collapseLength: 100 });
|
||||
const docsFromFile = reader.loadData(file);
|
||||
const docsFromContent = reader.loadDataAsContent(content);
|
||||
```
|
||||
|
||||
### Options
|
||||
|
||||
Basic:
|
||||
|
||||
- `streamingThreshold?`: The threshold for using streaming mode in MB of the JSON Data. CEstimates characters by calculating bytes: `(streamingThreshold * 1024 * 1024) / 2` and comparing against `.length` of the JSON string. Set `undefined` to disable streaming or `0` to always use streaming. Default is `50` MB.
|
||||
|
||||
- `ensureAscii?`: Wether to ensure only ASCII characters be present in the output by converting non-ASCII characters to their unicode escape sequence. Default is `false`.
|
||||
|
||||
- `isJsonLines?`: Wether the JSON is in JSON Lines format. If true, will split into lines, remove empty one and parse each line as JSON. Note: Uses a custom streaming parser, most likely less robust than json-ext. Default is `false`
|
||||
|
||||
- `cleanJson?`: Whether to clean the JSON by filtering out structural characters (`{}, [], and ,`). If set to false, it will just parse the JSON, not removing structural characters. Default is `true`.
|
||||
|
||||
- `logger?`: A placeholder for a custom logger function.
|
||||
|
||||
Depth-First-Traversal:
|
||||
|
||||
- `levelsBack?`: Specifies how many levels up the JSON structure to include in the output. `cleanJson` will be ignored. If set to 0, all levels are included. If undefined, parses the entire JSON, treat each line as an embedding and create a document per top-level array. Default is `undefined`
|
||||
|
||||
- `collapseLength?`: The maximum length of JSON string representation to be collapsed into a single line. Only applicable when `levelsBack` is set. Default is `undefined`
|
||||
|
||||

# Image Retrieval
|
||||
|
||||
LlamaParse `json` mode supports extracting any images found in a page object by using the `getImages` function. They are downloaded to a local folder and can then be sent to a multimodal LLM for further processing.
|
||||
|
||||
## Usage
|
||||
|
||||
We use the `getImages` method to input our array of JSON objects, download the images to a specified folder and get a list of ImageNodes.
|
||||
|
||||
```ts
|
||||
const reader = new LlamaParseReader();
|
||||
const jsonObjs = await reader.loadJson("../data/uber_10q_march_2022.pdf");
|
||||
const imageDicts = await reader.getImages(jsonObjs, "images");
|
||||
```
|
||||
|
||||
### Multimodal Indexing
|
||||
|
||||
You can create an index across both text and image nodes by requesting alternative text for the image from a multimodal LLM.
|
||||
|
||||
```ts
|
||||
import {
|
||||
Document,
|
||||
ImageNode,
|
||||
LlamaParseReader,
|
||||
OpenAI,
|
||||
VectorStoreIndex,
|
||||
} from "llamaindex";
|
||||
import { createMessageContent } from "llamaindex/synthesizers/utils";
|
||||
|
||||
const reader = new LlamaParseReader();
|
||||
async function main() {
|
||||
// Load PDF using LlamaParse JSON mode and return an array of json objects
|
||||
const jsonObjs = await reader.loadJson("../data/uber_10q_march_2022.pdf");
|
||||
// Access the first "pages" (=a single parsed file) object in the array
|
||||
const jsonList = jsonObjs[0]["pages"];
|
||||
|
||||
const textDocs = getTextDocs(jsonList);
|
||||
const imageTextDocs = await getImageTextDocs(jsonObjs);
|
||||
const documents = [...textDocs, ...imageTextDocs];
|
||||
// Split text, create embeddings and query the index
|
||||
const index = await VectorStoreIndex.fromDocuments(documents);
|
||||
const queryEngine = index.asQueryEngine();
|
||||
const response = await queryEngine.query({
|
||||
query:
|
||||
"What does the bar graph titled 'Monthly Active Platform Consumers' show?",
|
||||
});
|
||||
|
||||
console.log(response.toString());
|
||||
}
|
||||
|
||||
main().catch(console.error);
|
||||
```
|
||||
|
||||
We use two helper functions to create documents from the text and image nodes provided.
|
||||
|
||||
#### Text Documents
|
||||
|
||||
To create documents from the text nodes of the json object, we just map the needed values to a new `Document` object. In this case we assign the text as text and the page number as metadata.
|
||||
|
||||
```ts
|
||||
function getTextDocs(jsonList: { text: string; page: number }[]): Document[] {
|
||||
return jsonList.map(
|
||||
(page) => new Document({ text: page.text, metadata: { page: page.page } }),
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
#### Image Documents
|
||||
|
||||
To create documents from the images, we need to use a multimodal LLM to generate alt text.
|
||||
|
||||
For this we create `ImageNodes` and add them as part of our message.
|
||||
|
||||
We can use the `createMessageContent` function to simplify this.
|
||||
|
||||
```ts
|
||||
async function getImageTextDocs(
|
||||
jsonObjs: Record<string, any>[],
|
||||
): Promise<Document[]> {
|
||||
const llm = new OpenAI({
|
||||
model: "gpt-4o",
|
||||
temperature: 0.2,
|
||||
maxTokens: 1000,
|
||||
});
|
||||
const imageDicts = await reader.getImages(jsonObjs, "images");
|
||||
const imageDocs = [];
|
||||
|
||||
for (const imageDict of imageDicts) {
|
||||
const imageDoc = new ImageNode({ image: imageDict.path });
|
||||
const prompt = () => `Describe the image as alt text`;
|
||||
const message = await createMessageContent(prompt, [imageDoc]);
|
||||
|
||||
const response = await llm.complete({
|
||||
prompt: message,
|
||||
});
|
||||
|
||||
const doc = new Document({
|
||||
text: response.text,
|
||||
metadata: { path: imageDict.path },
|
||||
});
|
||||
imageDocs.push(doc);
|
||||
}
|
||||
|
||||
return imageDocs;
|
||||
}
|
||||
```
|
||||
|
||||
The returned `imageDocs` have the alt text assigned as text and the image path as metadata.
|
||||

||||

# LlamaParse
|
||||
|
||||
LlamaParse is an API created by LlamaIndex to efficiently parse files, e.g. it's great at converting PDF tables into markdown.
|
||||
|
||||
To use it, first login and get an API key from https://cloud.llamaindex.ai. Make sure to store the key as `apiKey` parameter or in the environment variable `LLAMA_CLOUD_API_KEY`.
|
||||
|
||||
Official documentation for LlamaParse can be found [here](https://docs.cloud.llamaindex.ai/).
|
||||
|
||||
## Usage
|
||||
|
||||
You can then use the `LlamaParseReader` class to load local files and convert them into a parsed document that can be used by LlamaIndex.
|
||||
See [LlamaParseReader.ts](https://github.com/run-llama/LlamaIndexTS/blob/main/packages/llamaindex/src/readers/LlamaParseReader.ts) for a list of supported file types:
|
||||
|
||||

|
||||
|
||||
They can be divided into two groups.
|
||||
|
||||
#### General params:
|
||||
|
||||
- `apiKey` is required. Can be set as an environment variable `LLAMA_CLOUD_API_KEY`
|

|
||||
- `verbose` shows progress of the parsing. Default is `true`
|
||||
- `ignoreErrors` set to false to get errors while parsing. Default is `true` and returns an empty array on error.
|
||||
|
||||
#### Advanced params:
|
||||
|
||||
- `resultType` can be set to `markdown`, `text` or `json`. Defaults to `text`. More information about `json` mode on the next pages.
|
||||
- `language` primarily helps with OCR recognition. Defaults to `en`. Click [here](../../../api/type-aliases/Language.md) for a list of supported languages.
|
||||
- `parsingInstructions?` Optional. Can help with complicated document structures. See this [LlamaIndex Blog Post](https://www.llamaindex.ai/blog/launching-the-first-genai-native-document-parsing-platform) for an example.
|
||||
- `skipDiagonalText?` Optional. Set to true to ignore diagonal text. (Text that is not rotated 0, 90, 180 or 270 degrees)
|
||||
- `invalidateCache?` Optional. Set to true to ignore the LlamaCloud cache. All document are kept in cache for 48hours after the job was completed to avoid processing the same document twice. Can be useful for testing when trying to re-parse the same document with, e.g. different `parsingInstructions`.
|
||||
- `doNotCache?` Optional. Set to true to not cache the document.
|
||||
- `fastMode?` Optional. Set to true to use the fast mode. This mode will skip OCR of images, and table/heading reconstruction. Note: Non-compatible with `gpt4oMode`.
|
||||
- `doNotUnrollColumns?` Optional. Set to true to keep the text according to document layout. Reduce reconstruction accuracy, and LLMs/embeddings performances in most cases.
|
||||
- `pageSeparator?` Optional. A templated page separator to use to split the text. If the results contain `{page_number}` (e.g. JSON mode), it will be replaced by the next page number. If not set the default separator `\\n---\\n` will be used.
|
||||
- `pagePrefix?` Optional. A templated prefix to add to the beginning of each page. If the results contain `{page_number}`, it will be replaced by the page number.
|
||||
- `pageSuffix?` Optional. A templated suffix to add to the end of each page. If the results contain `{page_number}`, it will be replaced by the page number.
|
||||
- `gpt4oMode` Deprecated. Use vendorMultimodal params. Set to true to use GPT-4o to extract content. Default is `false`.
|
||||
- `gpt4oApiKey?` Deprecated. Use vendorMultimodal params. Optional. Set the GPT-4o API key. Lowers the cost of parsing by using your own API key. Your OpenAI account will be charged. Can also be set in the environment variable `LLAMA_CLOUD_GPT4O_API_KEY`.
|
||||
- `boundingBox?` Optional. Specify an area of the document to parse. Expects the bounding box margins as a string in clockwise order, e.g. `boundingBox = "0.1,0,0,0"` to not parse the top 10% of the document.
|
||||
- `targetPages?` Optional. Specify which pages to parse by specifying them as a comma-separated list. First page is `0`.
|
||||
- `splitByPage` Wether to split the results, creating one document per page. Uses the set `pageSeparator` or `\n---\n` as fallback. Default is true.
|
||||
- `useVendorMultimodalModel` set to true to use a multimodal model. Default is `false`.
|
||||
- `vendorMultimodalModel?` Optional. Specify which multimodal model to use. Default is GPT4o. See [here](https://docs.cloud.llamaindex.ai/llamaparse/features/multimodal) for a list of available models and cost.
|
||||
- `vendorMultimodalApiKey?` Optional. Set the multimodal model API key. Can also be set in the environment variable `LLAMA_CLOUD_VENDOR_MULTIMODAL_API_KEY`.
|
||||
- `numWorkers` as in the python version, is set in `SimpleDirectoryReader`. Default is 1.

# JSON Mode
|
||||
|
||||
In JSON mode, LlamaParse will return a data structure representing the parsed object.
|
||||
|
||||
## Usage
|
||||
|
||||
For Json mode, you need to use `loadJson`. The `resultType` is automatically set with this method.
|
||||
More information about indexing the results on the next page.
|
||||
|
||||
```ts
|
||||
const reader = new LlamaParseReader();
|
||||
async function main() {
|
||||
// Load the file and return an array of json objects
|
||||
const jsonObjs = await reader.loadJson("../data/uber_10q_march_2022.pdf");
|
||||
// Access the first "pages" (=a single parsed file) object in the array
|
||||
const jsonList = jsonObjs[0]["pages"];
|
||||
// Further process the jsonList object as needed.
|
||||
}
|
||||
```
|
||||
|
||||
### Output
|
||||
|
||||
The result format of the response, written to `jsonObjs` in the example, follows this structure:
|
||||
|
||||
```json
|
||||
{
|
||||
"pages": [
|
||||
..page objects..
|
||||
],
|
||||
"job_metadata": {
|
||||
"credits_used": int,
|
||||
"credits_max": int,
|
||||
"job_credits_usage": int,
|
||||
"job_pages": int,
|
||||
"job_is_cache_hit": boolean
|
||||
},
|
||||
"job_id": string ,
|
||||
"file_path": string,
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Page objects
|
||||
|
||||
Within page objects, the following keys may be present depending on your document.
|
||||
|
||||
- `page`: The page number of the document.
|
||||
- `text`: The text extracted from the page.
|
||||
- `md`: The markdown version of the extracted text.
|
||||
- `images`: Any images extracted from the page.
|
||||
- `items`: An array of heading, text and table objects in the order they appear on the page.
|
||||
|
||||
### JSON Mode with SimpleDirectoryReader
|
||||
|
||||
All Readers share a `loadData` method with `SimpleDirectoryReader` that promises to return a uniform Document with Metadata. This makes JSON mode incompatible with SimpleDirectoryReader.
|
||||
|
||||
However, a simple work around is to create a new reader class that extends `LlamaParseReader` and adds a new method or overrides `loadData`, wrapping around JSON mode, extracting the required values, and returning a Document object.
|
||||
|
||||
```ts
|
||||
import { LlamaParseReader, Document } from "llamaindex";
|
||||
|
||||
class LlamaParseReaderWithJson extends LlamaParseReader {
|
||||
// Override the loadData method
|
||||
override async loadData(filePath: string): Promise<Document[]> {
|
||||
// Call loadJson method that was inherited by LlamaParseReader
|
||||
const jsonObjs = await super.loadJson(filePath);
|
||||
let documents: Document[] = [];
|
||||
|
||||
jsonObjs.forEach((jsonObj) => {
|
||||
// Making sure it's an array before iterating over it
|
||||
if (Array.isArray(jsonObj.pages)) {
|
||||
}
|
||||
const docs = jsonObj.pages.map(
|
||||
(page: { text: string; page: number }) =>
|
||||
new Document({ text: page.text, metadata: { page: page.page } }),
|
||||
);
|
||||
documents = documents.concat(docs);
|
||||
});
|
||||
return documents;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Now we have documents with page number as metadata. This new reader can be used like any other and be integrated with SimpleDirectoryReader. Since it extends `LlamaParseReader`, you can use the same params.
|
||||
|
||||
You can assign any other values of the JSON response to the Document as needed.

# MixedbreadAI
|
||||
|
||||
Welcome to the mixedbread embeddings guide! This guide will help you use the mixedbread ai's API to generate embeddings for your text documents, ensuring you get the most relevant information, just like picking the freshest bread from the bakery.
|
||||
|
||||
To find out more about the latest features, updates, and available models, visit [mixedbread.ai](https://mixedbread-ai.com/).
|
||||
|
||||
## Table of Contents
|
||||
|
||||
1. [Setup](#setup)
|
||||
2. [Usage with LlamaIndex](#integration-with-llamaindex)
|
||||
3. [Embeddings with Custom Parameters](#embeddings-with-custom-parameters)
|
||||
|
||||
## Setup
|
||||
|
||||
First, you will need to install the `llamaindex` package.
|
||||
|
||||
```bash
|
||||
pnpm install llamaindex
|
||||
```
|
||||
|
||||
Next, sign up for an API key at [mixedbread.ai](https://mixedbread.ai/). Once you have your API key, you can import the necessary modules and create a new instance of the `MixedbreadAIEmbeddings` class.
|
||||
|
||||
```ts
|
||||
import { MixedbreadAIEmbeddings, Document, Settings } from "llamaindex";
|
||||
```
|
||||
|
||||
## Usage with LlamaIndex
|
||||
|
||||
This section will guide you through integrating mixedbread embeddings with LlamaIndex for more advanced usage.
|
||||
|
||||
### Step 1: Load and Index Documents
|
||||
|
||||
For this example, we will use a single document. In a real-world scenario, you would have multiple documents to index, like a variety of breads in a bakery.
|
||||
|
||||
```ts
|
||||
Settings.embedModel = new MixedbreadAIEmbeddings({
|
||||
apiKey: "<MIXEDBREAD_API_KEY>",
|
||||
model: "mixedbread-ai/mxbai-embed-large-v1",
|
||||
});
|
||||
|
||||
const document = new Document({
|
||||
text: "The true source of happiness.",
|
||||
id_: "bread",
|
||||
});
|
||||
|
||||
const index = await VectorStoreIndex.fromDocuments([document]);
|
||||
```
|
||||
|
||||
### Step 2: Create a Query Engine
|
||||
|
||||
Combine the retriever and the embed model to create a query engine. This setup ensures that your queries are processed to provide the best results, like arranging the bread in the order of freshness and quality.
|
||||
|
||||
Models can require prompts to generate embeddings for queries, in the 'mixedbread-ai/mxbai-embed-large-v1' model's case, the prompt is `Represent this sentence for searching relevant passages:`.
|
||||
|
||||
```ts
|
||||
const queryEngine = index.asQueryEngine();
|
||||
|
||||
const query =
|
||||
"Represent this sentence for searching relevant passages: What is bread?";
|
||||
|
||||
// Log the response
|
||||
const results = await queryEngine.query(query);
|
||||
console.log(results); // Serving up the freshest, most relevant results.
|
||||
```
|
||||
|
||||
## Embeddings with Custom Parameters
|
||||
|
||||
This section will guide you through generating embeddings with custom parameters and usage with f.e. matryoshka and binary embeddings.
|
||||
|
||||
### Step 1: Create an Instance of MixedbreadAIEmbeddings
|
||||
|
||||
Create a new instance of the `MixedbreadAIEmbeddings` class with custom parameters. For example, to use the `mixedbread-ai/mxbai-embed-large-v1` model with a batch size of 64, normalized embeddings, and binary encoding format:
|
||||
|
||||
```ts
|
||||
const embeddings = new MixedbreadAIEmbeddings({
|
||||
apiKey: "<MIXEDBREAD_API_KEY>",
|
||||
model: "mixedbread-ai/mxbai-embed-large-v1",
|
||||
batchSize: 64,
|
||||
normalized: true,
|
||||
dimensions: 512,
|
||||
encodingFormat: MixedbreadAI.EncodingFormat.Binary,
|
||||
});
|
||||
```
|
||||
|
||||
### Step 2: Define Texts
|
||||
|
||||
Define the texts you want to generate embeddings for.
|
||||
|
||||
```ts
|
||||
const texts = ["Bread is life", "Bread is love"];
|
||||
```
|
||||
|
||||
### Step 3: Generate Embeddings
|
||||
|
||||
Use the `embedDocuments` method to generate embeddings for the texts.
|
||||
|
||||
```ts
|
||||
const result = await embeddings.embedDocuments(texts);
|
||||
console.log(result); // Perfectly customized embeddings, ready to serve.
|
||||
```

# MixedbreadAI
|
||||
|
||||
Welcome to the mixedbread ai reranker guide! This guide will help you use mixedbread ai's API to rerank search query results, ensuring you get the most relevant information, just like picking the freshest bread from the bakery.
|
||||
|
||||
To find out more about the latest features and updates, visit the [mixedbread.ai](https://mixedbread.ai/).
|
||||
|
||||
## Table of Contents
|
||||
|
||||
1. [Setup](#setup)
|
||||
2. [Usage with LlamaIndex](#integration-with-llamaindex)
|
||||
3. [Simple Reranking Guide](#simple-reranking-guide)
|
||||
4. [Reranking with Objects](#reranking-with-objects)
|
||||
|
||||
## Setup
|
||||
|
||||
First, you will need to install the `llamaindex` package.
|
||||
|
||||
```bash
|
||||
pnpm install llamaindex
|
||||
```
|
||||
|
||||
Next, sign up for an API key at [mixedbread.ai](https://mixedbread.ai/). Once you have your API key, you can import the necessary modules and create a new instance of the `MixedbreadAIReranker` class.
|
||||
|
||||
```ts
|
||||
import {
|
||||
MixedbreadAIReranker,
|
||||
Document,
|
||||
OpenAI,
|
||||
VectorStoreIndex,
|
||||
Settings,
|
||||
} from "llamaindex";
|
||||
```
|
||||
|
||||
## Usage with LlamaIndex
|
||||
|
||||
This section will guide you through integrating mixedbread's reranker with LlamaIndex.
|
||||
|
||||
### Step 1: Load and Index Documents
|
||||
|
||||
For this example, we will use a single document. In a real-world scenario, you would have multiple documents to index, like a variety of breads in a bakery.
|
||||
|
||||
```ts
|
||||
const document = new Document({
|
||||
text: "This is a sample document.",
|
||||
id_: "sampleDoc",
|
||||
});
|
||||
|
||||
Settings.llm = new OpenAI({ model: "gpt-3.5-turbo", temperature: 0.1 });
|
||||
|
||||
const index = await VectorStoreIndex.fromDocuments([document]);
|
||||
```
|
||||
|
||||
### Step 2: Increase Similarity TopK
|
||||
|
||||
The default value for `similarityTopK` is 2, which means only the most similar document will be returned. To get more results, like picking a variety of fresh breads, you can increase the value of `similarityTopK`.
|
||||
|
||||
```ts
|
||||
const retriever = index.asRetriever({
|
||||
similarityTopK: 5,
|
||||
});
|
||||
```
|
||||
|
||||
### Step 3: Create a MixedbreadAIReranker Instance
|
||||
|
||||
Create a new instance of the `MixedbreadAIReranker` class.
|
||||
|
||||
```ts
|
||||
const nodePostprocessor = new MixedbreadAIReranker({
|
||||
apiKey: "<MIXEDBREAD_API_KEY>",
|
||||
topN: 4,
|
||||
});
|
||||
```
|
||||
|
||||
### Step 4: Create a Query Engine
|
||||
|
||||
Combine the retriever and node postprocessor to create a query engine. This setup ensures that your queries are processed and reranked to provide the best results, like arranging the bread in the order of freshness and quality.
|
||||
|
||||
```ts
|
||||
const queryEngine = index.asQueryEngine({
|
||||
retriever,
|
||||
nodePostprocessors: [nodePostprocessor],
|
||||
});
|
||||
|
||||
// Log the response
|
||||
const response = await queryEngine.query("Where did the author grow up?");
|
||||
console.log(response);
|
||||
```
|
||||
|
||||
With mixedbread's Reranker, you're all set to serve up the most relevant and well-ordered results, just like a skilled baker arranging their best breads for eager customers. Enjoy the perfect blend of technology and culinary delight!
|
||||
|
||||
## Simple Reranking Guide
|
||||
|
||||
This section will guide you through a simple reranking process using mixedbread ai.
|
||||
|
||||
### Step 1: Create an Instance of MixedbreadAIReranker
|
||||
|
||||
Create a new instance of the `MixedbreadAIReranker` class, passing in your API key and the number of results you want to return. It's like setting up your bakery to offer a specific number of freshly baked items.
|
||||
|
||||
```ts
|
||||
const reranker = new MixedbreadAIReranker({
|
||||
apiKey: "<MIXEDBREAD_API_KEY>",
|
||||
topN: 4,
|
||||
});
|
||||
```
|
||||
|
||||
### Step 2: Define Nodes and Query
|
||||
|
||||
Define the nodes (documents) you want to rerank and the query.
|
||||
|
||||
```ts
|
||||
const nodes = [
|
||||
{ node: new BaseNode("To bake bread you need flour") },
|
||||
{ node: new BaseNode("To bake bread you need yeast") },
|
||||
];
|
||||
const query = "What do you need to bake bread?";
|
||||
```
|
||||
|
||||
### Step 3: Perform Reranking
|
||||
|
||||
Use the `postprocessNodes` method to rerank the nodes based on the query.
|
||||
|
||||
```ts
|
||||
const result = await reranker.postprocessNodes(nodes, query);
|
||||
console.log(result); // Like pulling freshly baked nodes out of the oven.
|
||||
```
|
||||
|
||||
## Reranking with Objects
|
||||
|
||||
This section will guide you through reranking when working with objects.
|
||||
|
||||
### Step 1: Create an Instance of MixedbreadAIReranker
|
||||
|
||||
Create a new instance of the `MixedbreadAIReranker` class, just like before.
|
||||
|
||||
```ts
|
||||
const reranker = new MixedbreadAIReranker({
|
||||
apiKey: "<MIXEDBREAD_API_KEY>",
|
||||
model: "mixedbread-ai/mxbai-rerank-large-v1",
|
||||
topK: 5,
|
||||
rankFields: ["title", "content"],
|
||||
returnInput: true,
|
||||
maxRetries: 5,
|
||||
});
|
||||
```
|
||||
|
||||
### Step 2: Define Documents and Query
|
||||
|
||||
Define the documents (objects) you want to rerank and the query.
|
||||
|
||||
```ts
|
||||
const documents = [
|
||||
{ title: "Bread Recipe", content: "To bake bread you need flour" },
|
||||
{ title: "Bread Recipe", content: "To bake bread you need yeast" },
|
||||
];
|
||||
const query = "What do you need to bake bread?";
|
||||
```
|
||||
|
||||
### Step 3: Perform Reranking
|
||||
|
||||
Use the `rerank` method to reorder the documents based on the query.
|
||||
|
||||
```ts
|
||||
const result = await reranker.rerank(documents, query);
|
||||
console.log(result); // Perfectly customized results, ready to serve.
|
||||
```

# Retriever
|
||||
|

A retriever in LlamaIndex is what is used to fetch `Node`s from an index using a query string.
|
||||
|

# المفاهيم على المستوى العالي
|
||||
|
||||
`تمت ترجمة هذه الوثيقة تلقائيًا وقد تحتوي على أخطاء. لا تتردد في فتح طلب سحب لاقتراح تغييرات.`
|
||||
|
||||
يساعدك LlamaIndex.TS في بناء تطبيقات قائمة على LLM (مثل Q&A و chatbot) على بيانات مخصصة.
|
||||
|
||||
في هذا الدليل عن المفاهيم على المستوى العالي، ستتعلم:
|
||||
|
||||
- كيف يمكن لـ LLM الإجابة على الأسئلة باستخدام بياناتك الخاصة.
|
||||
- المفاهيم الرئيسية والوحدات في LlamaIndex.TS لبناء خط أنابيب الاستعلام الخاص بك.
|
||||
|
||||
## الإجابة على الأسئلة عبر بياناتك
|
||||
|
||||
يستخدم LlamaIndex طريقة مكونة من مرحلتين عند استخدام LLM مع بياناتك:
|
||||
|
||||
1. **مرحلة الفهرسة**: إعداد قاعدة المعرفة، و
|
||||
2. **مرحلة الاستعلام**: استرداد السياق ذي الصلة من المعرفة لمساعدة LLM في الاستجابة لسؤال
|
||||
|
||||

|
||||
|
||||
تُعرف هذه العملية أيضًا باسم "استرجاع معزز للتوليد" (RAG).
|
||||
|
||||
يوفر LlamaIndex.TS أدوات أساسية لجعل كلا المرحلتين سهلتين للغاية.
|
||||
|
||||
دعنا نستكشف كل مرحلة بالتفصيل.
|
||||
|
||||
### مرحلة الفهرسة
|
||||
|
||||
يساعدك LlamaIndex.TS في إعداد قاعدة المعرفة باستخدام مجموعة من موصلات البيانات والفهارس.
|
||||
|
||||

|
||||
|
||||
[**محمّلات البيانات**](./modules/high_level/data_loader.md):
|
||||
موصل البيانات (أي `Reader`) يقوم بتجميع البيانات من مصادر بيانات مختلفة وتنسيقات بيانات مختلفة في تمثيل بسيط للـ `Document` (نص وبيانات تعريفية بسيطة).
|
||||
|
||||
[**المستندات / العقد**](./modules/high_level/documents_and_nodes.md): المستند هو حاوية عامة حول أي مصدر بيانات - على سبيل المثال، ملف PDF، نتائج واجهة برمجة التطبيقات، أو بيانات استرداد من قاعدة بيانات. العقد هو الوحدة الذرية للبيانات في LlamaIndex ويمثل "قطعة" من المستند الأصلي. إنه تمثيل غني يتضمن بيانات تعريفية وعلاقات (مع عقد أخرى) لتمكين عمليات الاسترجاع الدقيقة والتعبيرية.
|
||||
|
||||
[**فهارس البيانات**](./modules/high_level/data_index.md):
|
||||
بمجرد أن تقوم بتجميع بياناتك، يساعدك LlamaIndex في فهرسة البيانات في تنسيق سهل الاسترداد.
|
||||
|
||||
تحت الغطاء، يقوم LlamaIndex بتحليل المستندات الخام إلى تمثيلات وسيطة، وحساب تضمينات الناقلات، وتخزين بياناتك في الذاكرة أو على القرص.
|
||||
|
||||
"
|
||||
|
||||
### مرحلة الاستعلام
|
||||
|
||||
في مرحلة الاستعلام، يقوم خط الأنابيب للاستعلام بجلب السياق الأكثر صلة بناءً على استعلام المستخدم،
|
||||
ويمرر ذلك إلى LLM (جنبًا إلى جنب مع الاستعلام) لتوليد استجابة.
|
||||
|
||||
يمنح ذلك LLM معرفة محدثة ليست موجودة في بيانات التدريب الأصلية لديه،
|
||||
(مما يقلل أيضًا من الهلوسة).
|
||||
|
||||
التحدي الرئيسي في مرحلة الاستعلام هو الاسترجاع والتنسيق والاستدلال عبر قواعد المعرفة (المحتملة).
|
||||
|
||||
يوفر LlamaIndex وحدات قابلة للتركيب تساعدك في بناء ودمج خطوط أنابيب RAG لـ Q&A (محرك الاستعلام)، chatbot (محرك الدردشة)، أو كجزء من وكيل.
|
||||
|
||||
يمكن تخصيص هذه الكتل البنائية لتعكس تفضيلات التصنيف، وكذلك تركيبها للاستدلال عبر عدة قواعد معرفة بطريقة منظمة.
|
||||
|
||||

|
||||
|
||||
#### الكتل الأساسية
|
||||
|
||||
[**مسترجعات**](./modules/low_level/retriever.md):
|
||||
يحدد المسترجع كيفية استرجاع السياق ذي الصلة بكفاءة من قاعدة المعرفة (أي الفهرس) عند إعطاء استعلام.
|
||||
تختلف منطق الاسترجاع المحددة حسب الفهارس المختلفة، والأكثر شيوعًا هو الاسترجاع الكثيف ضد فهرس الناقل.
|
||||
|
||||
[**مركبات الاستجابة**](./modules/low_level/response_synthesizer.md):
|
||||
تقوم مركبة الاستجابة بتوليد استجابة من LLM باستخدام استعلام المستخدم ومجموعة معينة من أجزاء النص المسترجعة.
|
||||
|
||||
"
|
||||
|
||||
#### خطوط الأنابيب
|
||||
|
||||
[**محركات الاستعلام**](./modules/high_level/query_engine.md):
|
||||
محرك الاستعلام هو خط أنابيب شامل يتيح لك طرح الأسئلة على بياناتك.
|
||||
يأخذ استعلامًا بلغة طبيعية ويعيد استجابة، جنبًا إلى جنب مع السياق المرجعي المسترجع والممرر إلى LLM.
|
||||
|
||||
[**محركات الدردشة**](./modules/high_level/chat_engine.md):
|
||||
محرك الدردشة هو خط أنابيب شامل لإجراء محادثة مع بياناتك
|
||||
(عدة تفاعلات بدلاً من سؤال وجواب واحد).

# ما هو LlamaIndex.TS؟
|
||||
|
||||
`تمت ترجمة هذه الوثيقة تلقائيًا وقد تحتوي على أخطاء. لا تتردد في فتح طلب سحب لاقتراح تغييرات.`
|
||||
|
||||
LlamaIndex.TS هو إطار بيانات لتطبيقات LLM لاستيعاب وتنظيم والوصول إلى البيانات الخاصة أو الخاصة بالمجال. في حين أن حزمة Python متاحة أيضًا (انظر [هنا](https://docs.llamaindex.ai/en/stable/)), يوفر LlamaIndex.TS ميزات أساسية في حزمة بسيطة ، محسنة للاستخدام مع TypeScript.
|
||||
|
||||
## 🚀 لماذا LlamaIndex.TS؟
|
||||
|
||||
في جوهرها ، توفر LLMs واجهة لغة طبيعية بين البشر والبيانات المستنتجة. تأتي النماذج المتاحة على نطاق واسع محملة مسبقًا بكميات هائلة من البيانات المتاحة للجمهور ، من ويكيبيديا وقوائم البريد الإلكتروني إلى الكتب المدرسية وشفرة المصدر.
|
||||
|
||||
غالبًا ما تتطلب التطبيقات المبنية على LLMs تعزيز هذه النماذج بالبيانات الخاصة أو الخاصة بالمجال. للأسف ، يمكن توزيع هذه البيانات عبر تطبيقات ومخازن بيانات معزولة. إنها خلف واجهات برمجة التطبيقات ، في قواعد البيانات SQL ، أو محبوسة في ملفات PDF وعروض تقديمية.
|
||||
|
||||
هنا يأتي دور **LlamaIndex.TS**.
|
||||
|
||||
## 🦙 كيف يمكن أن يساعد LlamaIndex.TS؟
|
||||
|
||||
يوفر LlamaIndex.TS الأدوات التالية:
|
||||
|
||||
- **تحميل البيانات**: استيعاب البيانات الحالية الخاصة بك بتنسيقات `.txt`, `.pdf`, `.csv`, `.md` و `.docx` مباشرة.
|
||||
- **فهارس البيانات**: تنظيم البيانات الخاصة بك في تمثيلات وسيطة سهلة وفعالة للاستخدام من قبل LLMs.
|
||||
- **المحركات**: توفر واجهات الوصول إلى اللغة الطبيعية لبياناتك. على سبيل المثال:
|
||||
- محركات الاستعلام هي واجهات استرجاع قوية للإخراج المعزز بالمعرفة.

الفهرس هو الحاوية الأساسية والتنظيم لبياناتك. يدعم LlamaIndex.TS نوعين من الفهارس:
|
||||
|
||||
- `VectorStoreIndex` - سيقوم بإرسال أعلى `Node` الموجودة إلى LLM عند إنشاء استجابة. القيمة الافتراضية لأعلى `k` هي 2.
|
||||
- `SummaryIndex` - سيقوم بإرسال كل `Node` في الفهرس إلى LLM لإنشاء استجابة.
|
||||
|
||||
```typescript
|
||||
import { Document, VectorStoreIndex } from "llamaindex";
|
||||
|
||||
const document = new Document({ text: "اختبار" });
|

# محرك الاستعلامات (QueryEngine)
|
||||
|
||||
`تمت ترجمة هذه الوثيقة تلقائيًا وقد تحتوي على أخطاء. لا تتردد في فتح طلب سحب لاقتراح تغييرات.`
|
||||
|
||||
يقوم محرك الاستعلامات بتجميع "Retriever" و "ResponseSynthesizer" في أنبوبة، والتي ستستخدم سلسلة الاستعلام لاسترداد العقد ومن ثم إرسالها إلى LLM لتوليد استجابة.
|
||||
|
||||
```typescript
|
||||
const queryEngine = index.asQueryEngine();
|
||||
const response = await queryEngine.query("سلسلة الاستعلام");
|
||||
```
|
||||
|
||||
## محرك الاستعلام للأسئلة الفرعية
|
||||
|
||||
الفكرة الأساسية لمحرك الاستعلام للأسئلة الفرعية هي تقسيم استعلام واحد إلى استعلامات متعددة، والحصول على إجابة لكل من تلك الاستعلامات، ثم دمج تلك الإجابات المختلفة في استجابة واحدة متسقة للمستخدم. يمكنك أن تفكر فيها كتقنية "فكر في ذلك خطوة بخطوة" ولكن بتكرار مصادر البيانات الخاصة بك!
|
||||
|
||||
### البدء
|
||||
|
||||
أسهل طريقة لبدء تجربة محرك الاستعلام للأسئلة الفرعية هي تشغيل ملف subquestion.ts في [examples](https://github.com/run-llama/LlamaIndexTS/blob/main/examples/subquestion.ts).
|
||||
|
||||
```bash
|
||||
npx ts-node subquestion.ts
|
||||
```
|
||||
|
||||
"
|
||||
|
||||
### الأدوات
|
||||
|
||||
يتم تنفيذ محرك الاستعلام للأسئلة الفرعية باستخدام الأدوات. الفكرة الأساسية للأدوات هي أنها خيارات قابلة للتنفيذ لنموذج اللغة الكبيرة. في هذه الحالة، يعتمد محرك الاستعلام للأسئلة الفرعية على أداة QueryEngineTool، والتي كما تخمن هي أداة لتشغيل استعلامات على محرك الاستعلام. يتيح لنا ذلك إعطاء النموذج خيارًا للاستعلام عن وثائق مختلفة لأسئلة مختلفة على سبيل المثال. يمكنك أيضًا أن تتخيل أن محرك الاستعلام للأسئلة الفرعية يمكنه استخدام أداة تبحث عن شيء ما على الويب أو تحصل على إجابة باستخدام Wolfram Alpha.
|
||||
|
||||

# الوحدات الأساسية

||||
`تمت ترجمة هذه الوثيقة تلقائيًا وقد تحتوي على أخطاء. لا تتردد في فتح طلب سحب لاقتراح تغييرات.`
|
||||
|
||||
يوفر LlamaIndex.TS عدة وحدات أساسية، مقسمة إلى وحدات عالية المستوى للبدء السريع ووحدات منخفضة المستوى لتخصيص المكونات الرئيسية حسب الحاجة.
|
||||
|
||||
## وحدات عالية المستوى
|
||||
|
||||
- [**المستند**](./high_level/documents_and_nodes.md): يمثل المستند ملف نصي أو ملف PDF أو قطعة بيانات متتابعة أخرى.
|
||||
|
||||
- [**العقدة**](./high_level/documents_and_nodes.md): هو البناء الأساسي للبيانات. في أغلب الأحيان، تكون هذه أجزاء من المستند المقسمة إلى قطع قابلة للإدارة وصغيرة بما يكفي ليتم تغذيتها إلى نموذج التضمين و LLM.
|
||||
|
||||
- [**القارئ/المحمل**](./high_level/data_loader.md): القارئ أو المحمل هو شيء يأخذ المستند في العالم الحقيقي ويحوله إلى فئة المستند التي يمكن استخدامها في الفهرس الخاص بك والاستعلامات. ندعم حاليًا ملفات النص العادي وملفات PDF والمزيد الكثير.
|
||||
|
||||
- [**الفهارس**](./high_level/data_index.md): تخزن الفهارس العقد وتضمينات تلك العقد.
|
||||
|
||||
- [**محرك الاستعلامات**](./high_level/query_engine.md): محركات الاستعلامات هي التي تولد الاستعلام الذي تدخله وتعيد لك النتيجة. عمومًا، تجمع محركات الاستعلامات بين تعليمة مسبقة مبنية مع العقد المحددة من الفهرس الخاص بك لتعطي LLM السياق الذي يحتاجه للإجابة على استعلامك.
|
||||
|
||||
- [**محرك الدردشة**](./high_level/chat_engine.md): يساعدك محرك الدردشة على بناء روبوت دردشة سيتفاعل مع فهرسك.
|
||||
|
||||
## وحدة منخفضة المستوى
|
||||
|
||||
- [**LLM**](./low_level/llm.md): فئة LLM هي واجهة موحدة فوق مزود نموذج لغة كبير مثل OpenAI GPT-4 أو Anthropic Claude أو Meta LLaMA. يمكنك توريثها لكتابة موصل إلى نموذج اللغة الخاص بك.
|
||||
|
||||
- [**Embedding**](./low_level/embedding.md): يتم تمثيل التضمين كمتجه من الأرقام العائمة. نموذج التضمين الافتراضي لدينا هو text-embedding-ada-002 من OpenAI ويتكون كل تضمين يولده من 1,536 رقمًا عائمًا. نموذج التضمين الشائع الآخر هو BERT الذي يستخدم 768 رقمًا عائمًا لتمثيل كل عقدة. نوفر عددًا من الأدوات للعمل مع التضمين بما في ذلك 3 خيارات لحساب التشابه و Maximum Marginal Relevance.
|
||||
|
||||
- [**TextSplitter/NodeParser**](./low_level/node_parser.md): تعتبر استراتيجيات تقسيم النصوص مهمة للغاية لفعالية البحث في التضمين. حاليًا، على الرغم من أن لدينا قيمة افتراضية، إلا أنه لا يوجد حلاً مناسبًا للجميع. اعتمادًا على وثائق المصدر، قد ترغب في استخدام أحجام واستراتيجيات تقسيم مختلفة. حاليًا، ندعم التقسيم حسب الحجم الثابت، التقسيم حسب الحجم الثابت مع أجزاء تتداخل، التقسيم حسب الجملة، والتقسيم حسب الفقرة. يتم استخدام مقسم النصوص بواسطة NodeParser عند تقسيم `Document` إلى `Node`.
|
||||
|
||||
- [**Retriever**](./low_level/retriever.md): يقوم Retriever بتحديد العقد التي يتم استردادها من الفهرس. هنا، قد ترغب في محاولة استرداد عدد أكبر أو أقل من العقد لكل استعلام، تغيير وظيفة التشابه الخاصة بك، أو إنشاء استرداد خاص بك لكل حالة استخدام فردية في تطبيقك. على سبيل المثال، قد ترغب في وجود استرداد منفصل لمحتوى الشفرة مقابل محتوى النص.
|
||||
|
||||
- [**ResponseSynthesizer**](./low_level/response_synthesizer.md): يتحمل ResponseSynthesizer مسؤولية أخذ سلسلة استعلام واستخدام قائمة من العقد لإنشاء استجابة. يمكن أن يأخذ هذا الشكل العديد من الأشكال، مثل التكرار عبر جميع السياق وتحسين الإجابة، أو بناء شجرة من الملخصات وإرجاع الملخص الجذري.
|
||||
|
||||
- [**Storage**](./low_level/storage.md): في نقطة ما، سترغب في تخزين الفهارس والبيانات والمتجهات بدلاً من إعادة تشغيل نماذج التضمين في كل مرة. IndexStore و DocStore و VectorStore و KVStore هي تجريدات تتيح لك ذلك. مجتمعة، تشكل هذه التجريدات سياق التخزين. حاليًا، نسمح لك بالاحتفاظ بالتضمينات الخاصة بك في ملفات على نظام الملفات (أو نظام ملفات افتراضي في الذاكرة)، ولكننا نضيف أيضًا تكاملات مع قواعد بيانات المتجهات.

# مركب الاستجابة (ResponseSynthesizer)

`تمت ترجمة هذه الوثيقة تلقائيًا وقد تحتوي على أخطاء. لا تتردد في فتح طلب سحب لاقتراح تغييرات.`
|
||||
|
||||
مركب الاستجابة (ResponseSynthesizer) مسؤول عن إرسال الاستعلام والعقد وقوالب الاستفسار إلى LLM لتوليد استجابة. هناك بعض وسائط رئيسية لتوليد استجابة:
|
||||
|
||||
- `تحسين`: "إنشاء وتحسين" إجابة عن طريق المرور تتاليًا عبر كل قطعة نص مُسترجعة. يتم إجراء استدعاء LLM منفصل لكل عقدة. جيد للإجابات المفصلة.
|
||||
- `مضغوط وتحسين` (الافتراضي): "ضغط" الاستفسار أثناء كل استدعاء LLM عن طريق حشو أكبر عدد ممكن من قطع النص التي يمكن أن تتناسب مع حجم الاستفسار الأقصى. إذا كان هناك الكثير من القطع لتعبئتها في استفسار واحد، "إنشاء وتحسين" إجابة عن طريق المرور بعدة استفسارات مضغوطة. نفس العملية كـ `تحسين`، ولكن يجب أن تؤدي إلى مزيد من استدعاءات LLM أقل.
|
||||
- `ملخص الشجرة`: بناء شجرة بشكل متكرر بناءً على مجموعة من قطع النص والاستعلام، وإرجاع العقدة الجذرية كاستجابة. جيد لأغراض التلخيص.
|
||||
- `منشئ الاستجابة البسيط`: تطبيق الاستعلام على كل قطعة نص وتجميع الاستجابات في مصفوفة. يعيد سلسلة متصلة من جميع الاستجابات. جيد عندما تحتاج إلى تشغيل نفس الاستعلام بشكل منفصل على كل قطعة نص.
|
||||
|
||||
```typescript
|
||||
import { NodeWithScore, ResponseSynthesizer, TextNode } from "llamaindex";

بمجرد [تثبيت LlamaIndex.TS باستخدام NPM](installation) وإعداد مفتاح OpenAI الخاص بك، أنت الآن جاهز لبدء تطبيقك الأول:
|
||||
|
||||
في مجلد جديد:
|
||||
|
||||
```bash npm2yarn
|
||||
npm install typescript
|
||||
npm install @types/node
|
||||
npx tsc --init # إذا لزم الأمر
|
||||
```
|
||||
|
||||
أنشئ ملف `example.ts`. سيقوم هذا الكود بتحميل بعض البيانات المثالية، وإنشاء وثيقة، وفهرسة الوثيقة (مما ينشئ تضمينات باستخدام OpenAI)، ثم إنشاء محرك الاستعلام للإجابة على الأسئلة حول البيانات.
|
||||
|
||||
```ts
|
||||
// example.ts
|
||||
import fs from "fs/promises";
|
||||
import { Document, VectorStoreIndex } from "llamaindex";
|
||||
|
||||
async function main() {
|
||||
// تحميل المقالة من abramov.txt في Node
|
||||
const essay = await fs.readFile(
|
||||
"node_modules/llamaindex/examples/abramov.txt",
|
||||
"utf-8",
|
||||
);
|
||||
|
||||
// إنشاء كائن Document بواسطة المقالة
|
||||
const document = new Document({ text: essay });
|
||||
|
||||
// تقسيم النص وإنشاء التضمينات. تخزينها في VectorStoreIndex
|
||||
const index = await VectorStoreIndex.fromDocuments([document]);
|
||||
|
||||
// استعلام الفهرس
|
||||
const queryEngine = index.asQueryEngine();
|
||||
const response = await queryEngine.query("ماذا فعل الكاتب في الكلية؟");
|
||||
|
||||
// إخراج الاستجابة
|
||||
console.log(response.toString());
|
||||
}
|
||||
|
||||
main();
|
||||
```
|
||||
|
||||
ثم يمكنك تشغيله باستخدام
|
||||
|
||||
```bash
|
||||
npx ts-node example.ts
|
||||
```
