摘要：
For improving the effectiveness of cross-lingual information retrieval (CLIR), a domain ontology knowledge based method is presented to apply to C-E CLIR. In this study, the domain ontology knowledge is acquired from both source language user queries and target documents to select target translation and re-rank initial retrieval documents set. The C-E CLIR dataset from NTCIR-4 Workshop is used to evaluate the effectiveness of this method. Different from previous works, we make use of source language user queries in total C-E CLIR and compared with previous works, this method improved the precision.
