TREC 2009 at the University at Buffalo: Interactive Legal E-Discovery with enron emails

For the TREC 2009, the team from University at Buffalo, the State University of New York participated in the Legal E-Discovery track, working on the interactive search task. We explored indexing and searching at both the record level and the document level with the Enron email collection. We studied the usefulness of fielded search and document presentation features such as clustering documents based on email threads. For query formulation for the selected search topic, we combined a precision-oriented Specific Query method that a recall-oriented Generic Query method. Future evaluation of the effectiveness of these query techniques is still needed.
