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 6. Named Entity Recognition in Text

The next text mining tool we are going to add to our toolbox is actually from the domain of information extraction. When we talk about information extraction, we typically mean text mining techniques that use natural language processing to pull out key pieces of desired information from a large amount of unstructured text. I like to think of information extraction as being like a gold miner's sifting pan. Using these tools, we extract only the good stuff - the gold nuggets - and let the rest of the dirt fall away. In this chapter, the gold nuggets we will be sifting for are called named entities. Given a semi-structured or unstructured body of text, can we locate and extract all the named entities, such as people, places, or organizations, and leave the rest of the text behind?

In this chapter, we will learn:

  • What named entities are and why they are useful to search for

  • What the different techniques are for finding named entities, and what the benefits...
