Overview of this book

A primary concern with modern day applications is that they need to be dynamic, and for that, data access from the server side, data authentication, and security are very important. Angular leverages its services to create such state-of-the-art dynamic applications. This book will help you create and design customized services, integrate them into your applications, import third-party plugins, and make your apps perform better and faster. This book starts with a basic rundown on how you can create your own Angular development environment compatible with v2 and v4. You will then use Bootstrap and Angular UI components to create pages. You will also understand how to use controllers to collect data and populate them into NG UIs. Later, you will then create a rating service to evaluate entries and assign a score to them. Next, you will create "cron jobs" in NG. We will then create a crawler service to find all relevant resources regarding a selected headline and generate reports on it. Finally, you will create a service to manage accuracy and provide feedback about troubled areas in the app created. This book is up to date for the 2.4 release and is compatible with the 4.0 release as well, and it does not have any code based on the beta or release candidates.

What they all have in common is the meaning: "corpus" means "body".

Our evidence service needs a body to perform its magic. As we saw in the previous section, the TF-IDF factor cannot be calculated if we don't have body made out of hundreds of articles. So lets begin by creating a corpus.

Lets go back to the selected news item from the previous section.

Lets say we want to see if our application can find and organize enough evidence related to that news title and provide us some insight. One way to build the corpus around this article is to find articles related to important keywords in the original news item. Checking the contents of that news, we can find the following names and keywords...
