azure.ai.textanalytics package

class azure.ai.textanalytics.TextAnalyticsClient(endpoint, credential, **kwargs)[source]

The Text Analytics API is a suite of text analytics web services built with best-in-class Microsoft machine learning algorithms. The API can be used to analyze unstructured text for tasks such as sentiment analysis, key phrase extraction, and language detection. No training data is needed to use this API - just bring your text data. This API uses advanced natural language processing techniques to deliver best in class predictions.

Further documentation can be found in https://docs.microsoft.com/azure/cognitive-services/text-analytics/overview

Parameters
  • endpoint (str) – Supported Cognitive Services or Text Analytics resource endpoints (protocol and hostname, for example: https://westus2.api.cognitive.microsoft.com).

  • credential (TextAnalyticsApiKeyCredential or TokenCredential) – Credentials needed for the client to connect to Azure. This can be the an instance of TextAnalyticsApiKeyCredential if using a cognitive services/text analytics API key or a token credential from azure.identity.

Keyword Arguments
  • default_country_hint (str) – Sets the default country_hint to use for all operations. Defaults to “US”. If you don’t want to use a country hint, pass the empty string “”.

  • default_language (str) – Sets the default language to use for all operations. Defaults to “en”.

Example:

Creating the TextAnalyticsClient with endpoint and API key.
from azure.ai.textanalytics import TextAnalyticsClient, TextAnalyticsApiKeyCredential
endpoint = os.getenv("AZURE_TEXT_ANALYTICS_ENDPOINT")
key = os.getenv("AZURE_TEXT_ANALYTICS_KEY")

text_analytics_client = TextAnalyticsClient(endpoint, TextAnalyticsApiKeyCredential(key))
Creating the TextAnalyticsClient with endpoint and token credential from Azure Active Directory.
from azure.ai.textanalytics import TextAnalyticsClient
from azure.identity import DefaultAzureCredential

endpoint = os.getenv("AZURE_TEXT_ANALYTICS_ENDPOINT")
credential = DefaultAzureCredential()

text_analytics_client = TextAnalyticsClient(endpoint, credential=credential)
analyze_sentiment(inputs, language=None, **kwargs)[source]

Analyze sentiment for a batch of documents.

Returns a sentiment prediction, as well as sentiment scores for each sentiment class (Positive, Negative, and Neutral) for the document and each sentence within it.

See https://docs.microsoft.com/azure/cognitive-services/text-analytics/overview#data-limits for document length limits, maximum batch size, and supported text encoding.

Parameters
  • inputs (list[str] or list[TextDocumentInput]) – The set of documents to process as part of this batch. If you wish to specify the ID and language on a per-item basis you must use as input a list[TextDocumentInput] or a list of dict representations of TextDocumentInput, like {“id”: “1”, “language”: “en”, “text”: “hello world”}.

  • language (str) – The 2 letter ISO 639-1 representation of language for the entire batch. For example, use “en” for English; “es” for Spanish etc. If not set, uses “en” for English as default. Per-document language will take precedence over whole batch language. See https://aka.ms/talangs for supported languages in Text Analytics API.

Keyword Arguments
  • model_version (str) – This value indicates which model will be used for scoring, e.g. “latest”, “2019-10-01”. If a model-version is not specified, the API will default to the latest, non-preview version.
