CAS-ICT took part in the TREC conference for the first time this year. We have participated in three tracks of TREC-10. For adaptive filtering track, we paid more attention to feature selection and profile adaptation. For web track, we tried to integrate different ranking methods to improve system performance. For QA track, we focused on question type identification, named entity tagging and answer matching. This paper describes our methods in detail. Keywords: TREC-10, Filtering, Web track, QA 1.
