problem with epinions dataset

[hphphphphp]

hi;
here is my code but Does not produce anything just for epinions dataset.

Configuration conf = new Configuration();

    //	Resource resource = new Resource("rec/context/rating/trustsvd-test.properties");

// conf.addResource(resource);
conf.set("dfs.data.dir", "../data");

//conf.set("data.input.path", "filmtrust");
conf.set("data.input.path", "epinions");

// conf.set("data.splitter.ratio", "rating");
// conf.set("data.splitter.trainset.ratio", "0.8");

    conf.set("rec.factor.number", "10");
    conf.set("rec.iterator.maximum", "10");

         conf.set("rec.recommender.similarity.key" ,"user");
        conf.set("data.appender.class", "social");
    conf.set("data.appender.path", "test/test-append-dir");

Randoms.seed(1);
    TextDataModel dataModel = new TextDataModel(conf);
    dataModel.buildDataModel();

                RecommenderSimilarity similarity = new PCCSimilarity();
    similarity.buildSimilarityMatrix(dataModel);

    // get similarity values
    int numUser = ((SparseMatrix)dataModel.getTrainDataSet()).numRows();
    SymmMatrix similarityMatrix = similarity.getSimilarityMatrix();

    for (int i=0; i<numUser; i++) {
        for (int j=0; j<numUser; j++) {
            System.out.println("user_" + i + ", user_" + j + ", similarity: " + similarityMatrix.get(i, j));
        }
    }

It seems that you are using the rating file of Epinions with the trust file of FilmTrust.
Try this :

        conf.set("data.input.path", "epinions/rating");
        conf.set("data.appender.path" ,"epinions/trust");
