java.lang.Object

org.apache.uima.analysis_component.AnalysisComponent_ImplBase

org.apache.uima.analysis_component.Annotator_ImplBase

org.apache.uima.analysis_component.JCasAnnotator_ImplBase

ch.epfl.bbp.uima.ae.output.LdaCWriter

All Implemented Interfaces:

org.apache.uima.analysis_component.AnalysisComponent

public class LdaCWriter
extends org.apache.uima.fit.component.JCasAnnotator_ImplBase

Output Keeps into the LDA-C format:
[M] [term_1]:[count] [term_2]:[count] ... [term_N]:[count]
where [M] is the number of unique terms in the document, and the [count] associated with each term is how many times that term appeared in the document. Also writes the corresponding vocabulary file, one Keep per line.
The writer can be used separately:

 writer = new LdaCWriter.Writer(" ", corpusFile, vocabFile);
 writer.addDocument(wordList);
 writer.close();
