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.

Preface

Natural Language Processing using the Web Language Model


Using the Web Language Model (Web LM) API, we are able to do natural language processing. The language models are trained on web-scale, using data collected by Bing.

This API offers four key features:

  • Joint probability of a sequence of words
  • Conditional probability of one word following a sequence of words
  • Most likely words to follow a given sequence
  • Word breaking of strings without any spaces

To get started, add a new file, called WebLmView.xaml, to the View folder. In this view, we want to have two TextBox elements, one for our input query and one for the result View. In addition, we want four Button elements. Each of these will trigger one of the API features.

Next, we need to add a new ViewModel. Add a new file, called WebLmViewModel.cs, to the ViewModel folder. Add two string properties, corresponding to the input and output in the View. We also need to add four ICommand objects, which will be triggered when the buttons are pressed.
