In this paper, we propose a method of CrossLanguage Information Retrieval based on an integration of a probabilistic CLIR model and Probabilistic Latent Semantic Analysis (PLSA). PLSA is adopted to extract the information of translation probability from a parallel corpus. The information is utilized in a probabilistic CLIR model. Although the probabilistic CLIR model with PLSA is quite effective, it takes very long time in the processing. We therefore introduce an approximation method based on… CONTINUE READING
