In Knowledge Discovery, we integrate knowledge from Wikipedia, Yahoo Question/Answers, Open Directory Project and OpenMind to improve topic recognition. We showedlarge error reduction over previous state of art on Google Answers and Switchboard datasets. We extend the system to conversations to predict correct dialog turn using lexical and semantic features.
