Question
I'm trying to understand how to use the TreeTagger
http://www.ims.uni-stuttgart.de/projekte/corplex/TreeTagger/
wrapped by tt4j
http://reckart.github.io/tt4j/
to chunk some text.
I can't find any tutorial.
Thanks for the help
No correct solution
OTHER TIPS
The tt4j page was updated with useful code to get started:
import org.annolab.tt4j.*;
import static java.util.Arrays.asList;
public class Example {
public static void main(String[] args) throws Exception {
// Point TT4J to the TreeTagger installation directory. The executable is expected
// in the "bin" subdirectory - in this example at "/opt/treetagger/bin/tree-tagger"
System.setProperty("treetagger.home", "/opt/treetagger");
TreeTaggerWrapper tt = new TreeTaggerWrapper<String>();
try {
tt.setModel("/opt/treetagger/models/english.par:iso8859-1");
tt.setHandler(new TokenHandler<String>() {
public void token(String token, String pos, String lemma) {
System.out.println(token + "\t" + pos + "\t" + lemma);
}
});
tt.process(asList(new String[] { "This", "is", "a", "test", "." }));
}
finally {
tt.destroy();
}
}
}
A pom.xml (Maven) like this should be enough to get it working:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
