Subject [jira] [Created] (CONNECTORS-1088) Augment Tika extractor to allow full use of boilerpipe content extraction
Date Tue, 28 Oct 2014 07:58:33 GMT
Karl Wright created CONNECTORS-1088:

             Summary: Augment Tika extractor to allow full use of boilerpipe content extraction
                 Key: CONNECTORS-1088
             Project: ManifoldCF
          Issue Type: Improvement
          Components: Tika extractor
    Affects Versions: ManifoldCF 1.8, ManifoldCF 2.0
            Reporter: Karl Wright
            Assignee: Karl Wright
             Fix For: ManifoldCF 1.8, ManifoldCF 2.0

Boilerpipe has the ability to process content further than our current Tika extractor implementation
allows.  Specifically, we should be allowing a user to specify a BoilerPipe extractor class,
from within the following package (or other places too, one expects):

If the extractor is specified, then our ContentHandler creation code in the Tika extractor
changes from:

            ContentHandler handler = new BodyContentHandler(w);


            ContentHandler handler = new BodyContentHandler(w);
            boilerpipe = "de.l3s.boilerpipe.extractors." + boilerpipe;
            try {
              ClassLoader loader = BoilerpipeExtractor.class.getClassLoader();
              Class extractorClass = loader.loadClass(boilerpipe);

              BoilerpipeExtractor boilerpipeExtractor = (BoilerpipeExtractor)extractorClass.newInstance();
              handler = new BoilerpipeContentHandler(handler, boilerpipeExtractor);

             } catch (ClassNotFoundException e) {
                log.warn("BoilerpipeExtractor " + boilerpipe + " not found!");
             } catch (InstantiationException e) {
                log.warn("Could not instantiate " + boilerpipe);
             } catch (Exception e) {
