Automatic Cross-Language Retrieval Using Latent Semantic Indexing

Susan T. Dumais, Todd A. Letsche, Michael L. Littman and Thomas K. Kandauer

We describe a method for fully automated cross-language document retrieval in which no query translation is required. Queries in one language can retrieve documents in other languages (as well as the original language). This is accomplished by a method that automatically constructs a multilingual semantic space using Latent Semantic Indexing (LSI). Strong test results for the cross-language LSI (CLLSI) method are presented for a new French-English collection. We also provide evidence that this automatic method performs comparably to a retrieval method based on machine translation (MT-LSI), and explore several practical training methods. By all available measures, CL-LSI performs quite well and is widely applicable.
