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.

Summary


In this chapter, we learned the basics of network analysis and graph theory, including how to measure a network and describe its properties. We learned why the degree, distance, and centrality of a network are important. We also investigated the various graph data formats that are used in network analysis, and considered which ones are most effective for which types of graphs. Finally, we implemented a real-world project where we build networks of software developers that had worked together in the RubyForge ecosystem. We learned various techniques for exploring the networks, including how to build smaller and more detailed networks, and how to explore component subgraphs. We discovered a few techniques for focusing on a single node and building out ego networks, and eventually we implemented those ego networks into a view of a component and its change over time.

In the next few chapters, we will turn our attention to text mining. Specifically, in Chapter 5, Sentiment Analysis in...
