Drexel at TREC 2007: Question Answering

The TREC Question Answering Track presented several distinct challenges to participants in 2007. Participants were asked to create a system which discovers the answers to factoid and list questions about people, entities, organizations and events, given both blog and newswire text data sources. In addition, participants were asked to expose interesting information nuggets which exist in the data collection, which were not uncovered by the factoid or list questions. This year is the first time the Intelligent Information Processing group at Drexel has participated in the TREC Question Answering Track. As such, our goal was the development of a Question Answering system framework to which future enhancements could be made, and the construction of simple components to populate the framework. The results of our system this year were not significant; our primary accomplishment was the establishment of a baseline system which can be improved upon in 2008 and going forward.
