Java Question

edit config file in stanford pos tagger

i have tagged a simple sentence and this is my code:

package tagger;

import edu.stanford.nlp.tagger.maxent.MaxentTagger;

public class myTag {

public static void main(String[] args) {

MaxentTagger tagger = new MaxentTagger("D:/tagger/english-bidirectional-distsim.tagger");

String sample = "i go to school by bus";

String tagged = tagger.tagString(sample);



this is the output:

Reading POS tagger model from D:/tagger/english-bidirectional-distsim.tagger ... done [3.0 sec].
i_LS go_VB to_TO school_NN by_IN bus_NN

after editing the properties file it doesn't have any effect at all.
for example i have changed the tag separator to ( * ) but in the output it still prints ( _ ).

how could i use the model config file in eclipse?

You can load Properties file and pass it to the constructor of MaxEnt, something like this:

Properties props = new Properties();
props.load(new FileReader("path/to/properties"));
MaxentTagger tagger = new MaxentTagger("D:/tagger/english-bidirectional-distsim.tagger", props);

You can also set properties in props object directly:

props.setProperty("tagSeparator", "*");

NB: if you use the original properties file and it fails with exception like /u/nl
p/data/pos_tags_are_useless/egw4-reut.512.clusters (No such file or directory)

then remove arch and trainFile attributes.
