Natural Language Processing with Java Cookbook

By: Richard M. Reese

Overview of this book

Natural Language Processing (NLP) has become one of the prime technologies for processing very large amounts of unstructured data from disparate information sources. This book includes a wide set of recipes and quick methods that solve challenges in text syntax, semantics, and speech tasks. At the beginning of the book, you'll learn important NLP techniques, such as identifying parts of speech, tagging words, and analyzing word semantics. You will learn how to perform lexical analysis and use machine learning techniques to speed up NLP operations. With independent recipes, you will explore techniques for customizing your existing NLP engines/models using Java libraries such as OpenNLP and the Stanford NLP library. You will also learn how to use NLP processing features from cloud-based sources, including Google and Amazon Web Services (AWS). You will master core tasks, such as stemming, lemmatization, part-of-speech tagging, and named entity recognition. You will also learn about sentiment analysis, semantic text similarity, language identification, machine translation, and text summarization. By the end of this book, you will be ready to become a professional NLP expert using a problem-solution approach to analyze any sort of text, sentence, or semantic word.

Finding sentences using the Java core API

There are several approaches to performing SBD using the Java core JDK. While they will not always yield good results as do other more advanced SBD techniques, they may prove quite useful in some situations while not incurring the expense of specialized NLP models.

In this recipe, we will examine two approaches:

  • The first approach will use the split method of the String class
  • The second approach uses a simple regular expression

Getting ready

Create a new Java project. Since we will not be using any specialized libraries, the project does not need to be a Maven project.
