Query Expansion via Link Analysis of Wikipedia for CLIR.
Chih-Chuan Hsu, Yu-Te Li, Youwei Chen, Shih-Hung Wu · 2008
In this paper, we report how we do the query expansion in the NTCIR-7 IR4QA subtask. We submit the results of nine runs of this subtask, which is cross-language information retrieval (CLIR) from English to traditional Chinese, simplified Chinese and Japanese in the official T-run, D-run and DN-run. In these runs, we use the Google online translation service to translate query terms and Wikipedia as an information resource for query expansion (QE), in addition to the OKAPI query expansion.
