Topic Classification Framework for Stanbol

Currently there is a single implementation of a topic classifier enhancement engine by ogrisel, started in earlier versions of Stanbol. Besides some issues that still need to be fixed in the last version of the engine, it would be interesting to have others implementation alternatives based for example on known resources like Apache Mahout or OpenNLP. A common Framework/API fully integrated in Stanbol for Training/Use a Content Classifer should be developed.
