Class DependencyFileCollectionReader

java.lang.Object

CollectionReader_ImplBase

org.apache.ctakes.dependency.parser.cr.DependencyFileCollectionReader

public class DependencyFileCollectionReader
extends CollectionReader_ImplBase

This collection reader reads in dependency tree training/test data in a tab- delimited format. See note below for DEPENDENCY_FILE_PARAM for details about this format. Each file will correspond to a "document" - i.e. getNext() will populate the CAS with information from a file.

Field Detail

DEPENDENCY_FILE_PARAM

public static final java.lang.String DEPENDENCY_FILE_PARAM

"DependencyFile" is a required, single, string parameter that specifies the location of a data file that contains dependency data in it. The format of the file should have one word per line, with tab-delimited features similar to the CONLL format.
