Cognitive Services Episode 5 - Natural search with the Linguistics API

So far in this course, we saw the high level AI concepts and we built a chatbot bound to a LUIS app. Our bot is already able to respond to IT-related questions and can tackle day-to-day conversations thanks to QnA Maker.

While QnA Maker is a great tool for textual questions/answers scenarios, it cannot be used when dealing with documents or data stored within a database and customers are not always willing to relocate their information into QnA Maker even when feasible. 

In this episode, we'll see how to take advantage of another Cognitive Service, namely the Linguistic Analysis API to perform Natural Search Queries against external sources of information. I will show two use-cases: querying a SharePoint document center and interacting with a SQL database but the principles depicted here may be used to query any kind of information system.
