Mastering Social Media Mining with R

Overview of this book

With an increase in the number of users on the web, the content generated has increased substantially, bringing in the need to gain insights into the untapped gold mine that is social media data. For computational statistics, R has an advantage over other languages in providing readily-available data extraction and transformation packages, making it easier to carry out your ETL tasks. Along with this, its data visualization packages help users get a better understanding of the underlying data distributions while its range of "standard" statistical packages simplify analysis of the data. This book will teach you how powerful business cases are solved by applying machine learning techniques on social media data. You will learn about important and recent developments in the field of social media, along with a few advanced topics such as Open Authorization (OAuth). Through practical examples, you will access data from R using APIs of various social media sites such as Twitter, Facebook, Instagram, GitHub, Foursquare, LinkedIn, Blogger, and other networks. We will provide you with detailed explanations on the implementation of various use cases using R programming. With this handy guide, you will be ready to embark on your journey as an independent social media analyst.

Foursquare is a local search services company that offers its service on the mobile platform as well as a website. Log in to Foursquare as a developer in order to get the idea of the API request and response patterns. On registering, a unique OAuth token is generated.

In the developer's login, open the explorer from the list of links on the left-hand side panel. Here's a screenshot of the developer's landing page:

In the explorer panel, we can see how the request is being sent, which can again be replicated in R using either the function fromJSON or GET. The data will be retrieved in the JSON format. Here's the screenshot of the explorer panel:

We can now execute the API request from R using the function fromJSON. First, let's get the user details:

fromJSON("https://api.foursquare.com/v2/users/self?oauth_token=<Paste your OAuth token here>")

We get the following output:

The preceding API request provides many details about the user such as name, location...
