This paper describes first experiments on BMIR-J2 using the Toshiba NEAT information retrieval system. Experimental retrieval results indicate that the probabilistic information retrieval model originally developed for English text transfers well to the Japanese language using both word-based and character-based indexing. Additional experiments report retrieval results comparing various approaches to query processing and retrieval performance for the different query categories defined within BMIR-J2.The BMIR-J2 Collection is the largest generally available information retrieval test set for Japanese text retrieval.
