Class CreateAssertionLuceneIndexFromDelimitedFile

java.lang.Object

org.apache.ctakes.dictionary.assertion.CreateAssertionLuceneIndexFromDelimitedFile

public class CreateAssertionLuceneIndexFromDelimitedFile
extends Object

Driver for populating a Lucene Index with assertion cue phrases, so that the tokenization of the dictionary entries matches the tokenization that will be done to clinical text during pipeline processing. Just as the pipeline can use a file of hyphenated words to control which words should be considered as a single token, the creation of the dictionary entries can use a file of hyphenated words so the dictionary entries are tokenized in the same way as the clinical text will be.
