Universities of Avignon and Lyon III at TREC 2008: Enterprise Track

摘要

The Enterprise track of TREC 2008 comprised of the same two tasks as in the previous years: an ad-hoc document search and an expert search. * The document search consisted in retrieving documents that best matched real-life queries submitted by users to the CSIRO corporation. Systems were allowed to retrieve and rank up to a 1000 documents. * The expert search consisted in locating the CSIRO staff who is best able to respond to the query formulated by the users. This year was our first participation in TREC-ENT. We explored three major approaches to information retrieval using various existing methods and systems. These approaches ranged from domain knowledge mapping to QA.
