Combining fields in known-item email search
Emails are examples of structured documents with various fields. These fields can be exploited to enhance the retrieval effectiveness of an Information Retrieval (IR) system that searches mailing list archives. In recent experiments of the TREC 2005 Enterprise track, various fields were applied to varying degrees of success by the participants. In this work, using a field-based weighting model, we investigate the retrieval performance attainable by each field, and examine when fields evidence should be combined or not.
