Abstract

The Text REtrieval Conference (TREC) is a series of workshops designed to advance the state-of-the-art in information retrieval by providing the infrastructure necessary for large-scale evaluation of retrieval methodologies. Each TREC consists of a collection of "tracks", subtasks that focus research attention on specific challenges. A diverse set of tracks invigorates TREC and makes TREC attractive to a broad set of participants. This talk will give a brief summary of the history of TREC and then describe one or two tracks in more detail covering task definition, evaluation methodology, and lessons learned.

Available tracks include:

Cross-language search

Entity resolution

Information filtering

Legal ediscovery

Question Answering

Search over blogs and tweets

Search over media other than text

Search within clinical settings (including search over medical records)

Web search
