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


Automatic text summarization is a field that is growing in importance as the volume of data in the world increases. There are numerous approaches to text summarization, but all of them rely on the construction of mathematical representations of the words and sentences in a document, then, through extractive or abstractive methods, building a program that can reduce a document to its most important parts. We reviewed three of the common extractive summarization libraries that can be integrated into our Python code: an NLTK-based summarizer, a Gensim-based approach, and a new package called Sumy with its numerous embedded summarizers. We then compared the different approaches to text summarization by using the same text sample and passing it through different summarization algorithms to see how they differed.

It is good that in this chapter, we have begun thinking about what makes an important sentence or a key word. In the next chapter, we will be learning about topic modeling, which...
