The SEMEX tool for question answering is presented. Its architecture and features for extracting from input text a network of concept nodes that index syntax-based logical forms, are described. Methods are shown for decomposing questions into boolean combinations of question patterns and for using the concept network and logical forms together with WordNet for question answering. SEMEX's encouraging performance against the TREC 2005 question answering test set is discussed.
