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.

Why look for named entities?


Named Entity Recognition (NER) is the act of locating certain people, places, and things in a larger body of text. Finding the specific entities that are being discussed in a text is a critical task for creating better chatbots, for creating better Question Answering (QA) systems, or for helping speech recognition systems do a better job. When I am preparing dinner in my kitchen, if I ask Amazon Echo to tell me about meatloaf, will I get a description of the food, or of Meatloaf the musician? (For those who are wondering, I tried this at home and Echo responded with a description of the musician!)

Note

Named entity recognition should not be confused with the tasks we performed in Chapter 3, Entity Matching, earlier in this book. The two tasks are similar in that they both deal with nouns, called entities, but the comparison ends there. While NER tries to locate the entities in text, EM tries to figure out whether two entities are the same thing.
