Azure is a public cloud computing platform. Azure can be used for many purposes, such as analytics, virtual computing, and networking. In particular, Azure provides a powerful set of cognitive services, including a cognitive services text analytics tool. This tool on the Azure form can be used to analyze several aspects of text data, such as the language of origin or whether the text is positive or negative. Because Azure provides so many options for data analysis, it is prudent for modern IT workers to be comfortable working with Azure.

In particular, Azure provides a powerful API for sentiment analysis. Sentiment analysis is using natural language processing (NLP) to determine the tone of text data, or whether a statement is positive or negative. Sentiment analysis is important to modern businesses because it helps them automate analysis of product reviews and company feedback. A business can rapidly determine if a product is being received favorably by its customers, among many other uses.

This hands-on lab will introduce you to what the Azure text analytics tool is. You will gain valuable experience in creating a text analytics service and using this tool to analyze text data.
