Wen-Cheng Lin, Hsin‐Hsi Chen · 2002
This paper deals with Chinese, English and Japanese multilingual information retrieval. Several merging strategies, including raw-score merging, round-robin merging, normalized-score merging, and normalized-by-top-k merging, were investigated. Experimental results show that centralized approach is better than distributed approach. In distributed approach, normalized-by-top-k with consideration of translation penalty outperforms the other merging strategies.
