Chinese Query Expansion Based on Related Term Group
2005 International Conference on Natural Language Processing and Knowledge Engineering
Preserved Fulltext
This paper describes our work at the fifth NTCIR workshop on the subtasks of monolingual information retrieval (IR). Query expansions using automatically acquired related term groups were explored.

Experiments show that our method achieves an average 13.1%
