In this paper we investigate the use of surface text patterns for a Maximum Entropy based Question Answering (QA) system. These text patterns are collected automatically in an un- supervised fashion using a collection of trivia question and answer pairs as seeds. These pat- terns are used to generate features for a statis- tical question answering system. We report our results on the TREC-10 question set.
