This paper briefly describes Toshiba Knowledge Media Laboratory's recent research efforts for effective information retrieval and access. Firstly, I will mention the main research topics that are being tackled by our information access group, including document retrieval, speech-input/multimedia question answering, and evaluation metrics. Secondly, I will focus on the problem of cross-language information retrieval and access, and describe a system called BRIDJE (Bi-directional Retriever/Information Distiller for Japanese and English), which achieved many gold-medal performances at the recent NTCIR (a.k.a. Asian TREC) workshop. Finally, I will conclude the paper by mentioning some unsolved problems and suggesting possible directions for future Information Access research.
