I see. You're not working from the current repository, you're working from 3.0.0-incubating. Those files were erroneously included in that release. > "The training-data.libsvm file will not be generated during classification. > It's only generated during training", I understood this part. > > "LIBSVM-formatted features and labels" this part is I am not clear, how > these are generated from training data? They're generated from the features created by the RelationFeaturesExtractors I pointed you to in RelationExtractorAnnotator. The conversion from Feature objects to LIBSVM-formatted feature strings is performed by ClearTK, specifically by the LIBSVMStringOutcomeDataWriter. (You can see that the models are trained with that data writer class in RelationExtractorTrain.) > Is it based on SVM algorithm? The LIBSVM-format for providing features and labels is defined by LIBSVM (http://www.csie.ntu.edu.tw/~cjlin/libsvm/). It's basically <label> <feature>:<value> <feature>:<value> ...
