The TREC conference series is co-sponsored by the National Institute of Standards and Technology (NIST) and the Information Technology Office of the Defense Advanced Research Projects Agency (DARPA) as part of the TIPSTER Text Program. The goal of the conference series is to encourage research in information retrieval from large text applications by providing a large test collection, uniform scoring procedures, and a forum for organizations interested in comparing their results. Attendance at TREC conferences is restricted to those researchers and developers who have performed the TREC retrieval tasks and to selected government personnel.
TREC has two main tasks, ad hoc retrieval and filtering. The ad hoc task investigates the performance of systems that search a static set of documents using novel topics; the filtering task investigates the performance of systems that use standing queries to search new streams of documents. In addition, TREC has smaller "tracks" that allow participants to focus on particular subproblems of the retrieval task.
The high-level goal of the Interactive Track is the investigation of searching as an interactive task by examining the process as well as the outcome. The remainder of this page comprises information basic to the definition of the track for TREC-7. For additional information about TREC and its schedules see the TREC homepage.
