We propose a mixed language query disambiguation approach by using co-occurrence information from monolingual data only. A mixed language query consists of words in a primary language and a secondary language. Our method translates the query into monolingual queries in either language. Two novel features for disambiguation, namely contextual word voting and 1-best contextual word, are introduced and compared to a baseline feature, the nearest neighbor. Average query translation accuracy for the two features are and , compared to the baseline accuracy of . . | Mixed Language Query Disambiguation Pascale FUNG LIU Xiaohu and CHEUNG Chi Shun HKUST Human Language Technology Center Department of Electrical and Electronic Engineering University of Science and Technology HKƯST Clear Water Bay Hong Kong pascale Ixiaohu eepercy @ Abstract We propose a mixed language query disambiguation approach by using co-occurrence information from monolingual data only.

The Web is also a powerful platform for another application interactive spoken language query systems. Traditionally such systems were implemented on stand-alone kiosks. Now we can easily use the Web as a platform. Information such as airline schedules movie reservation car trading etc. can all be included in HTML files to be accessed by a generic spoken interface to the Web browser Zue 1995 DiDio 1997 Raymond 1997 Fung et al. 1998a . Our team has built a multilingual spoken language interface to the Web named SALSA Fung et al. 1998b Fung et al. 1998a Ma and Fung 1998 . Users can use speech to surf the net via various links as well as issue search commands such as Show me the latest movie of Jacky Chan . The system recognizes commands and queries in English Mandarin and Cantonese as well as mixed language sentences. Until recently most of the search engines handle keyword based queries where the user types in a series of strings without syntactic structure. The choice of key words in this case determines the success rate
