Learning Microsoft Cognitive Services - Second Edition

By: Leif Larsen

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.

Adding Autosuggest to the user interface

As textboxes in WPF do not contain any auto-suggestion features, we need to add some on our own. We are going to use a third-party package, so install the WPFTextBoxAutoComplete package through the NuGet package manager, in our example project.

In the MainView.xaml file, add the following attribute to the starting Window tag:

    xmlns:behaviors="clr-namespace: WPFTextBoxAutoComplete;     assembly=WPFTextBoxAutoComplete" 

We will also need to make sure that the TextBox binding for our search query updates whenever the user enters data. This can be done by making sure the Text attribute looks as follows:

Text="{Binding SearchQuery...
