Natural Language Processing with Java Cookbook

How it works...

The ColumnDataClassifier instance is initialized using the properties file:

ColumnDataClassifier columnDataClassifier =     new ColumnDataClassifier("FlowersAndSpices.prop");

This file is duplicated in the following code sequence. It consists of several feature declarations and the names of the training and test files. These features are documented at https://nlp.stanford.edu/nlp/javadoc/javanlp/edu/stanford/nlp/classify/ColumnDataClassifier.html:

# FeaturesuseClassFeature=true1.usePrefixSuffixNGrams=true1.maxNGramLeng=41.minNGramLeng=1# Training inputtrainFileFlowersAndSpices.traintestFileFlowersAndSpices.test

The makeClassifier method creates the actual classifier using the training file:
