In this chapter, we looked at the Google+ API. We also discussed how to register a project on the Google Developer Console and how to enable the desired API(s) for our project.
The chapter started with an example that showed how to perform a search using the Google+ API. The discussion was then built upon this example in order to embed the use of the API in a web application. Taking advantage of Flask, a micro framework for web development that allows to get up and running with a few lines of code, we built a web GUI to show the results of a search session.
The next step was to analyze textual notes from a user or page. After downloading the user activities and storing them in the JSON Lines format, we discussed a few details of TF-IDF as a statistical approach to extract interesting keywords from a piece of text.
In the next chapter, we will move our attention to the field of question answering, and we will do so by approaching the Stack Overflow API.
