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.

Chapter 7. Automatic Text Summarization

In an era of information overload, the objective of text summarization is to write a program that can reduce the size of a text, while preserving the main points of its meaning. The task is somewhat similar to the way an architect might create a scale model of a building. The scale model gives the viewer a sense of the important parts about the structure, but does so with a smaller size footprint, fewer details, and without the same expense in time or materials.

Consider Reddit, a news-oriented social media site, with its thousands of news articles posted daily by users. Is it possible to generate a short summary of a news article that preserves the key facts and general meaning of the original story? A few Reddit users created summary bots to do exactly this. These so-called TLDR bots (too long; didn't read) post summaries of user-submitted news stories, usually including a link to the original story and statistics to show by what percentage they reduced...
