Natural Language Processing with Java

Using NLP APIs

There are a number of NLP API classes that support SBD. Some are rule-based, whereas others use models that have been trained using common and uncommon text. We will illustrate the use of sentence detection classes using the OpenNLP, Stanford, and LingPipe APIs.

The models can also be trained. The discussion of this approach is illustrated in the Training a Sentence Detector model section of this chapter. Specialized models are needed when working with specialized text such as medical or legal text.

Using OpenNLP

OpenNLP uses models to perform SBD. An instance of the SentenceDetectorME class is created, based on a model file. Sentences are returned by the sentDetect method, and position information is returned by the sentPosDetect ...
