Semi-supervised NMF Topic Model

Semi-supervised Non-negative Matrix Factorization (NMF) Topic Model udvider uovervåget NMF ved at inkorporere brugerleverede startord eller etiketbegrænsninger for at styre opdagede emner mod domænespecifikke temaer. Den faktoriserer en dokument-ord-matrix til fortolkelige ikke-negative komponenter, samtidig med at den respekterer leksikale forhåndsviden, hvilket giver sammenhængende, applikationsafstemte emner selv fra beskedne korpusser.
