TREC 11 Experiments at CAS-ICT: Filtering and Web.

Abstract

CAS-ICT took part in the TREC conference for the second time this year and we undertook two tracks of TREC-11. For filtering track, we have submitted results of all three subtasks. In adaptive filtering, we paid more attention to undetermined documents processing, profile building and adaptation. In batch filtering and routing, a centroid-based classifier is used with preprocessed samples. For Web track, we have submitted results of both two subtasks. Different factors are considered to improve the overall performance of our Web systems. This paper describes our methods in detail. Keywords: TREC-11, Filtering, Web track 1.
