CROSS-LANGUAGE TEXT RETRIEVAL BY QUERY TRANSLATION USING TERM REWEIGHTING

摘要

In a dictionary-based query translation for cross-language text retrieval, transfer ambiguity is one of the main causes of performance deterioration, but the problem has not received significant attention in this field. To resolve transfer ambiguity, this paper proposes a two-phase query translation based on term reweighting, which uses a bilingual transfer dictionary, originally designed for machine translation.
