Overview of this book

Natural Language Processing (NLP) allows you to take any sentence and identify patterns, special names, company names, and more. The second edition of Natural Language Processing with Java teaches you how to perform language analysis with the help of Java libraries, while constantly gaining insights from the outcomes. You’ll start by understanding how NLP and its various concepts work. Having got to grips with the basics, you’ll explore important tools and libraries in Java for NLP, such as CoreNLP, OpenNLP, Neuroph, and Mallet. You’ll then start performing NLP on different inputs and tasks, such as tokenization, model training, parts-of-speech and parsing trees. You’ll learn about statistical machine translation, summarization, dialog systems, complex searches, supervised and unsupervised NLP, and more. By the end of this book, you’ll have learned more about NLP, neural networks, and various other trained models in Java for enhancing the performance of NLP applications.

Extracting relationships for a question-answer system


In this section, we will examine an approach for extracting relationships that can be useful for answering queries. Possible/candidate queries include the following:

  • Who is/was the 14th president of the United States?
  • What is the first president's home town?
  • When was Herbert Hoover president?

The process of answering these types of questions is not easy. We will demonstrate one approach to answer certain types of questions, but we will simplify many aspects of this process. Even with these restrictions, we will find that the system responds well to the queries.

This process consists of several steps:

  1. Finding word dependencies
  2. Identifying the type of questions
  3. Extracting its relevant components
  4. Searching for the answer
  5. Presenting the answer

We will show the general framework to identify whether a question is of the types who, what, when, or where. Next, we will investigate some of the issues required to answer the who type questions.
