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 (str or TokenCredential) – Credentials needed for the client to connect to Azure. This can be the cognitive services/text analytics subscription key or a token credential from azure.identity.
- Keyword Arguments
Example:
from azure.ai.textanalytics import TextAnalyticsClient endpoint = os.getenv("AZURE_TEXT_ANALYTICS_ENDPOINT") key = os.getenv("AZURE_TEXT_ANALYTICS_KEY") text_analytics_client = TextAnalyticsClient(endpoint, key)
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://aka.ms/talangs for the list of enabled languages.
- 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.
