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


In this chapter, we learned how to connect entities even when there is no common identifier for them. This task, called entity matching, is broadly applicable to many domains, and is one of the oldest tasks in data processing. Once we have matched entities, we are able to perform data mining on sets that were previously unconnected.

To do so, we tackled common strategies for entity matching, attribute-based, disjoint sets, and context-based. We learned several techniques for estimating whether strings are similar, including edit distances like Hamming and Levenshtein, and phonetic encodings such as Soundex, and we learned how to use blocking techniques to reduce or eliminate pairwise testing. Since it is important to evaluate the effectiveness of our entity matching methods, we learned how to calculate false positive and false negative rates. Finally, we tested our knowledge by designing an entity matching procedure for a real-world problem using data from two separate collections...
