An Interactive Chinese to English Retrieval System

In this paper, we describe an interactive Chinese to English retrieval system that takes in Chinese queries and retrieves relevant documents in Chinese and English from document collections of both languages. We first describe the components for Chinese language processing and for Chinese-to-English query translation. Then we present the complete interactive system, through which a user is able to select and edit query terms manually in both Chinese and English, review the retrieval results in different presentation modes, and conduct retrieval using enhanced queries based on relevant documents or document clusters in either language. The system integrates CLARIT advanced technologies of natural language processing and information management, and is intended as a prototype and evaluation environment for identifying effective strategies to facilitate users with different levels of language proficiency in retrieving relevant documents from multilingual data collections.
