We describe the SEMEX question-answering system and report its performance in the TREC 2005 Question Answering track. Since this was SE- MEX's first year participating in the TREC evaluations, implementation teething pains were expected and indeed encountered. Nevertheless, perfor- mance against difficult factoid and list questions was supportive of the ques- tion answering approach that was implemented.
