Mastering Data Mining with Python - Find patterns hidden in your data

By: Megan Squire

Overview of this book

Data mining is an integral part of the data science pipeline. It is the foundation of any successful data-driven strategy – without it, you'll never be able to uncover truly transformative insights. Since data is vital to just about every modern organization, it is worth taking the next step to unlock even greater value and more meaningful understanding. If you already know the fundamentals of data mining with Python, you are now ready to experiment with more interesting, advanced data analytics techniques using Python's easy-to-use interface and extensive range of libraries. In this book, you'll go deeper into many often overlooked areas of data mining, including association rule mining, entity matching, network mining, sentiment analysis, named entity recognition, text summarization, topic modeling, and anomaly detection. For each data mining technique, we'll review the state-of-the-art and current best practices before comparing a wide variety of strategies for solving each problem. We will then implement example solutions using real-world data from the domain of software engineering, and we will spend time learning how to understand and interpret the results we get. By the end of this book, you will have solid experience implementing some of the most interesting and relevant data mining techniques available today, and you will have achieved a greater fluency in the important field of Python data analytics.

A real project


To put our new knowledge about graphs and social networks to use, we will use data about the software developers working on free, libre, and open source (FLOSS) projects developed using the Ruby programming language. As we learned in Chapter 3, Entity Matching when we tackled entity matching between projects, many Ruby programmers used the website RubyForge.org between 2003 and 2013 to create projects and collaborate. In this chapter, we are going to use this same data to learn how the social structure of this community changed over those ten years.

RubyForge developers can be placed into a social network where the developers themselves are the nodes or vertices, and the fact that they worked on a project together represents the edge or link between the nodes. We could also count how many projects they worked on together to create a weight for the link. If two developers only worked together once, the link is weaker than if the two developers worked together on dozens of projects...
