Question

i try to implement LSA semantic search using TML library.here is my code where rep1 is a folder that i create and dossier is a folder where i put my txt documents.

  public static void main(String[] args) throws Exception {

        Repository repository = new Repository("C:\rep1");

        repository.addDocumentsInFolder("C:/dossier");

        System.out.println("Documents added to repository successfully!");

        SearchResultsCorpus corpus = new SearchResultsCorpus("type:document");
        corpus.getParameters().setTermSelectionCriterion(TermSelection.DF);
        corpus.getParameters().setTermSelectionThreshold(0);
        corpus.getParameters().setDimensionalityReduction(DimensionalityReduction.NUM);
        corpus.getParameters().setDimensionalityReductionThreshold(50);
        corpus.getParameters().setTermWeightGlobal(GlobalWeight.Entropy);
        corpus.getParameters().setTermWeightLocal(LocalWeight.LOGTF);
        corpus.load(repository);

        System.out.println("Corpus loaded and Semantic space calculated");
        System.out.println("Total documents:" + corpus.getPassages().length);

        PassagesSimilarity distances = new PassagesSimilarity();
        distances.setCorpus(corpus);
        distances.start();

        distances.printResults();


    }

but I have this error!
