The most important objective of this chapter is to gather data across some of the most common social networks. We will look mainly at Twitter and Facebook and try to give you enough details about the API and how to effectively use them to get relevant data. We will also talk about the data dictionary for scrapped data, and how we can build some cool apps using some of the stuff we learned so far.
We will start with one of the most popular and open social media that is completely public. This means that practically, you can gather entire Twitter stream, which is payable, while you can capture one percent of the stream for free. In the context of business, Twitter is a very rich resource of information such as public sentiments and emerging topics.
Let's get directly to face the main challenge of getting the tweets relevant to your use case.
