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.

Tools for text summarization


Since our focus in this book is data mining with Python, we will focus on understanding some of the tools, libraries, and applications designed for text summarization in a Python environment. However, if you ever find yourself in a non-Python environment, or if you have a special case where you want to use an off-the-shelf or non-Python solution, you will be glad to know that there are dozens of other text summarization tools for other programming environments, many of which require no programming at all. In fact, the autotldr bot we discussed at the beginning of this chapter uses a package called SUMMRY, which has an API that is accessible via REST and returns JSON. You can read more about SUMMRY at http://smmry.com/api.

Here we will discuss three Python solutions: a simple NLTK-based method, a Gensim-based method, and a Python summarization package called Sumy.
