- Abstract
- Reviews the overall results of the TREC experiments in information retrieval, which differed from other information retrieval research projects in that the document collections used in the research were massive, and the groups participating in the collaborative evaluation are among the main organizations in the field. Reviews the findings of TREC, the way in which it operates and the specialist 'tracks' it supports and concentrates on european involvement in TREC, examining the participants and the emergence of European TREC like exercises
