TextAnalysisClient class

A client for interacting with the text analysis features in Azure Cognitive Language Service.

The client needs the endpoint of a Language resource and an authentication method such as an API key or AAD. The API key and endpoint can be found in the Language resource page in the Azure portal. They will be located in the resource's Keys and Endpoint page, under Resource Management.

Examples for authentication:

API Key

import { TextAnalysisClient, AzureKeyCredential } from "@azure/ai-text-analytics";

const endpoint = "https://<resource name>.cognitiveservices.azure.com";
const credential = new AzureKeyCredential("<api key>");

const client = new TextAnalysisClient(endpoint, credential);

Azure Active Directory

See the @azure/identity package for more information about authenticating with Azure Active Directory.

import { TextAnalysisClient } from "@azure/ai-text-analytics";
import { DefaultAzureCredential } from "@azure/identity";

const endpoint = "https://<resource name>.cognitiveservices.azure.com";
const credential = new DefaultAzureCredential();

const client = new TextAnalysisClient(endpoint, credential);

Constructors

TextAnalysisClient(string, KeyCredential, TextAnalysisClientOptions)

The API key and endpoint can be found in the Language resource page in the Azure portal. They will be located in the resource's Keys and Endpoint page, under Resource Management.

Example

import { TextAnalysisClient, AzureKeyCredential } from "@azure/ai-text-analytics";

const credential = new DefaultAzureCredential();

const client = new TextAnalysisClient(endpoint, credential);

Methods

analyze<ActionName>(ActionName, LanguageDetectionInput[], AnalyzeActionParameters<ActionName> & TextAnalysisOperationOptions)

Runs a predictive model to determine the language that the passed-in input strings are written in, and returns, for each one, the detected language as well as a score indicating the model's confidence that the inferred language is correct. Scores close to 1 indicate high certainty in the result. 120 languages are supported.

See https://docs.microsoft.com//azure/cognitive-services/language-service/concepts/data-limits for data limits.

Examples

Language detection

const documents = [<input strings>];
const countryHint = "us";
const results = await client.analyze("LanguageDetection", documents, countryHint);

for (let i = 0; i < results.length; i++) {
  const result = results[i];
  if (result.error) {
    // a document has an error instead of results
  } else {
    const { name, confidenceScore, iso6391Name } = result.primaryLanguage;
  }
}

See https://docs.microsoft.com//azure/cognitive-services/language-service/language-detection/overview for more information on language detection.

analyze<ActionName>(ActionName, string[], string, AnalyzeActionParameters<ActionName> & TextAnalysisOperationOptions)

Runs a predictive model to determine the language that the passed-in input strings are written in, and returns, for each one, the detected language as well as a score indicating the model's confidence that the inferred language is correct. Scores close to 1 indicate high certainty in the result. 120 languages are supported.

See https://docs.microsoft.com//azure/cognitive-services/language-service/concepts/data-limits for data limits.

Examples

Language detection

const documents = [<input strings>];
const countryHint = "us";
const results = await client.analyze("LanguageDetection", documents, countryHint);

for (const result of results) {
  if (result.error) {
    // a document has an error instead of results
  } else {
    const { name, confidenceScore, iso6391Name } = result.primaryLanguage;
  }
}

See https://docs.microsoft.com//azure/cognitive-services/language-service/language-detection/overview for more information on language detection.

analyze<ActionName>(ActionName, string[], string, AnalyzeActionParameters<ActionName> & TextAnalysisOperationOptions)

Runs a predictive model to perform the action of choice on the input strings. See $AnalyzeActionName for a list of supported actions.

The layout of each item in the results array depends on the action chosen. For example, each PIIEntityRecognition document result consists of both entities and redactedText where the former is a list of all Pii entities in the text and the latter is the original text after all such Pii entities have been redacted from it.

See https://docs.microsoft.com//azure/cognitive-services/language-service/concepts/data-limits for data limits.

Examples

Opinion mining

const documents = ["The food and service aren't the best"];
const results = await client.analyze("SentimentAnalysis", documents, {
  includeOpinionMining: true,
});

for (const result of results) {
  if (result.error) {
    // a document has an error instead of results
  } else {
    const { sentiment, confidenceScores, sentences } = result;
    for (const { sentiment, confidenceScores, opinions } of sentences) {
      for (const { target, assessments } of opinions) {
        const { text, sentiment, confidenceScores } = target;
        for (const { text, sentiment } of assessments) {
