Microsoft's Text Analytics API is part of the Cortana Intelligence Suite, specifically a Cognitive Services that assists with turning unstructured text into more meaningful information. The set of tools has been used by numerous Microsoft customers to improve the customer experience by better understanding customer feedback.
Now, some new capabilities have been added, according to the Technet blog:
We are excited to announce the launch of the following new capabilities. Sentiment analysis can now be performed in English, Spanish, French and Portuguese, and key phrases can be extracted from text in English, Spanish, German and Japanese. These features are in addition to our market-leading ability to recognize the language of text in 120 languages and topic detection for English documents.
Microsoft notes that the sentiment analysis tools can be combined with the Bot Framework and Language Understanding Intelligence Service to create bots that can understand whether a user response is positive or negative. As the blog points out:
Customers such as Ziosk are using the Text Analytics API to provide a more granular understanding of their customer’s experience. Al Pappa, head of Business Intelligence at Ziosk, says, “Thanks to Text Analytics by Azure Machine Learning, we are able to incorporate guest sentiment into our actionable guest feedback platform that delivers a comprehensive view of guest satisfaction and server performance.”
