- Ralf D. Brown. 1998. Automatically-Extracted Thesauri for Cross-Language IR: When Better is Worse. Abstract: A statistical algorithm for extracting bilingual term dictionaries (thesauri) from parallel text is presented, along with reenements for improving their size and accuracy. Somewhat paradoxically , increasing the accuracy of the extracted thesaurus can in fact reduce the performance of an IR system using it to perform query translation for cross-language information retrieval.
