// Package textanalytics implements the Azure ARM Textanalytics service API version v2.0.
//
// 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/en-us/azure/cognitive-services/text-analytics/overview
