In this paper, we explored how to use meta-data information in information retrieval task. We presented a new language model that is able to take advantage of the category information for documents to improve the retrieval accuracy. We compared the new language model with the traditional language model over the TREC4 dataset where the collection information for documents is obtained using the k...

High-variability phonetic training is effective in the acquisition of foreign language sounds. Previous studies have largely focused on small sets of contrasts, and have not controlled for the quantity of prior or simultaneous exposure to new sounds. The current study examined the effectiveness of phonetic training in full-inventory foreign language consonant acquisition by listeners with no pr...

Since the Web consists of documents in various domains or genres, the method for Cross-Language Information Retrieval (CLIR) of Web documents should be independent of a particular domain. In this paper, we propose a CLIR method which employs a Web directory provided in multiple language versions (such as Yahoo!). In the proposed method, feature terms are first extracted from Web documents for e...
