Using OpenNLP to find entities in text

In this recipe, we will show one way of using OpenNLP to identify entities in a document. This technique does not use regular expressions, but rather a neural network model trained on date type entities.

Specifically, we will use the NameFinderME class, which uses the maximum entropy approach. We will download and use a model trained to detect dates in text. We will use another model to tokenize the text.

Getting ready

To prepare, we need to do the following:

1. Create a new Maven project.
2. Add the following dependency to the POM file:

<dependency>
    <groupId>org.apache.opennlp</groupId>
    <artifactId>opennlp-tools</artifactId>
    <version>1.9.0&lt...
