CLEF 2002 — Overview of Results

In its third year, the CLEF campaign has again seen considerable growth on multiple fronts. While the explosive growth in the number of participants has slowed somewhat, the number of actual experiments has grown considerably, as has their complexity (more data to process and more languages to handle). The main tracks of the CLEF 2002 campaign attracted 37 participating groups who submitted nearly 300 different experiments. In this overview, a description of the tracks and tasks, and a summary of the principal research results are given. As for the last two years, we have also examined the multilingual test collection produced as a result of the campaign with respect to the completeness of its relevance assessments, with very favorable findings.
