Document name in id2outcome file

[lakhani...@gmail.com]

Hello Dear people,
I am using multilabel classification and generating report.
In the file id2outcome.txt file, I am getting document and id and scores per class.
I want to have document name instead of id in id2outcome file.
Can somebody tell me how I can get that?

Thank you in advance

Hi,

I took a brief look at the pipeline for multi-label document-mode instance ids.  For sequence classification, there is a method, TextClassificationTarget.setSuffix(String aSuffix) that can be used in the Reader, to add a string suffix to the unit id as printed in the id2outcome file.  (This method is currently nonfunctional for some of the OutcomeId reports, and needs a bug report, but the functionality exists up until the OutcomeId report.)

I didn't find any similar method for document-mode classification, so I suggest altering getFullId(JCas jcas) in org.dkpro.tc.core.feature.InstanceIdFeature as follows:

    private static String getFullId(JCas jcas)

        throws TextClassificationException

    {

        JCasId jcasId = JCasUtil.selectSingle(jcas, JCasId.class);

        DocumentMetaData dmd = DocumentMetaData.get(jcas);

        String documentName = dmd.getDocumentId();

        return "" + jcasId.getId() + "-" + documentName;

    }

I ran it on org.dkpro.tc.examples.multi.document.MekaComplexConfigurationMultiDemo, and the id2outcome files show filenames.

Best,

Emily

Thank you Emily,
It worked.
I have another question.
Can we get accuracy, precision, Recall etc. without storing them in file.
Right now they are in excel file, which is unable to read using java.
I have to show those results other than excel file.

Perhaps org.dkpro.tc.evaluation.Id2Outcome, and the dkpro-tc-evaluation module in general, have what you need?
