Package net.ontopia.topicmaps.classify Description

To classify content, use the SimpleClassifier class. Note that most of the APIs are INTERNAL, and so may change at any time.

If you need more flexibility, it is possible to use the INTERNAL APIs directly. Below is example code showing how to output a ranked list of the terms found in a particular document.

    // load the topic map
    TopicMapIF topicmap = ImportExportUtils.getReader(args[0]).read();

    // create classifier
    TopicMapClassification tcl = new TopicMapClassification(topicmap);

    // read document
    ClassifiableContentIF cc = ClassifyUtils.getClassifiableContent(args[1]);

    // classify document
    tcl.classify(cc);

    // dump the ranked terms
    TermDatabase tdb = tcl.getTermDatabase();
    tdb.dump(50);
