constructor

new AlibabaTongyiEmbeddings(fields?): AlibabaTongyiEmbeddings
Parameters
- Optional fields: Partial<AlibabaTongyiEmbeddingsParams> & {
  apiKey?: string;
  verbose?: boolean;
  }
Returns AlibabaTongyiEmbeddings
Overrides Embeddings.constructor
- Defined in libs/langchain-community/src/embeddings/alibaba_tongyi.ts:78

Properties

apiKey

apiKey: string

batchSize

batchSize: number = 24

The maximum number of documents to embed in a single request. This is limited by the AlibabaTongyi API to a maximum of 2048.

modelName

modelName: "text-embedding-v2" = "text-embedding-v2"

Model name to use

parameters

parameters: undefined | {
text_type?: "query" | "document";
}

Type declaration

Optional text_type?: "query" | "document"
取值：query 或者 document，默认值为 document 说明：文本转换为向量后可以应用于检索、聚类、分类等下游任务，对检索这类非对称任务为了达到更好的检索效果建议区分查询文本（query）和底库文本（document）类型, 聚类、分类等对称任务可以不用特殊指定，采用系统默认值"document"即可

stripNewLines

stripNewLines: boolean = true

Whether to strip new lines from the input text.

Methods

embedDocuments

embedDocuments(texts): Promise<number[][]>
Method to generate embeddings for an array of documents. Splits the documents into batches and makes requests to the AlibabaTongyi API to generate embeddings.
Parameters
- texts: string[]
  Array of documents to generate embeddings for.
Returns Promise<number[][]>
Promise that resolves to a 2D array of embeddings for each document.
Overrides Embeddings.embedDocuments
- Defined in libs/langchain-community/src/embeddings/alibaba_tongyi.ts:111

embedQuery

embedQuery(text): Promise<number[]>
Method to generate an embedding for a single document. Calls the embeddingWithRetry method with the document as the input.
Parameters
- text: string
  Document to generate an embedding for.
Returns Promise<number[]>
Promise that resolves to an embedding for the document.
Overrides Embeddings.embedQuery
- Defined in libs/langchain-community/src/embeddings/alibaba_tongyi.ts:142
