Learning Microsoft Cognitive Services - Second Edition

Overview of this book

Microsoft has revamped its Project Oxford to launch the all new Cognitive Services platform-a set of 30 APIs to add speech, vision, language, and knowledge capabilities to apps. This book will introduce you to 24 of the APIs released as part of Cognitive Services platform and show you how to leverage their capabilities. More importantly, you'll see how the power of these APIs can be combined to build real-world apps that have cognitive capabilities. The book is split into three sections: computer vision, speech recognition and language processing, and knowledge and search. You will be taken through the vision APIs at first as this is very visual, and not too complex. The next part revolves around speech and language, which are somewhat connected. The last part is about adding real-world intelligence to apps by connecting them to Knowledge and Search APIs. By the end of this book, you will be in a position to understand what Microsoft Cognitive Service can offer and how to use the different APIs.

  • /news: Get top news articles, based on category
  • /news/search: Get news articles based on a search query
  • /news/trendingtopics: Get top trending news topics

In our smart-house application, we will add the first two, while we will only cover the last one theoretically.

Note

If you have not already done so, sign up for the Bing News Search API at https://portal.azure.com.

News from queries

A lot of the groundwork for query-based news searches have already been done in the web search sample. To search for news based on given queries, we need to add a new function in the BingSearch class.

Open the BingSearch.cs file and add a new function called SearchNews. This should accept a string and a SafeSearch parameter. The function should be marked as async, and return a Task<BingNewsResponse> object:

public async Task<BingNewsResponse> SearchNews(string query, SafeSearch...
