Depending on data availability, the track may also involve Tamil and Malay documents. A track studying user interaction with text retrieval systems. All participating groups follow a common experimental protocol that provides insights into user searching. A track designed to foster research on the effects of query variability and analysis on retrieval performance. Each participant constructs several different versions of existing TREC topics.
All groups then run all versions of the topics.
For each of a set of 500 questions, systems produce a text extract that answers the question. A track that investigates the effects of speech recognition errors on retrieval performance. The task to be performed in TREC-9 is still to be determined. Please contact the track coordinator as soon as possible if you are interested in this track. A track featuring ad hoc search tasks on a document set that is a snapshot of the World Wide Web.
