Query Based Topic Modeling
Eduardo H. Ramírez, Ramón Brena · IGI Global eBooks · 2011
Finally, in order to compare the QTM results with models generated by other methods we have developed probabilistic metrics that formalize the notion of semantic coherence using probabilistic concepts and can be used to validate overlapping and incomplete clustering using multi-labeled corpora. They show that the proposed method can produce models of comparable, or even superior quality, than those produced with state of the art probabilistic methods.
