cc.mallet.topics.tui.DMRLoader

All Implemented Interfaces:

java.io.Serializable

public class DMRLoader
extends java.lang.Object
implements java.io.Serializable

This class loads data into the format for the MALLET Dirichlet-multinomial regression (DMR). DMR topic models learn topic assignments conditioned on observed features.

The input format consists of two files, one for text and the other for features. The "text" file consists of one document per line. This class will tokenize and remove stopwords.

The "features" file contains whitespace-delimited features in this format: blue heavy width=12.08 Features without explicit values ("blue" and "heavy" in the example) are set to 1.0.
