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


After finishing this chapter, we now have a functional understanding of how sentiment analysis works, and we have compared many different strategies that the mainstream sentiment analysis tools use to accomplish this goal. We paid special attention to the Vader tool which comes as standard with the Python NLTK, since it is well-tested and straightforward to use. To learn how to use its sentiment intensity scoring system, we calculated the sentiment for a few different real-world datasets, both messy chat data and somewhat more structured e-mail data.

In the next chapter, we will continue to hone our skills in text mining, but instead of looking at the emotion conveyed by an entire sentence, we will focus our attention on locating entities within sentences. This task, called named entity recognition, is slightly related to the entity matching task we looked at in Chapter 3, Entity Matching, in that in both cases we are working with entities such as people or organizations. However...
