Abstract
This paper describes Ricoh’s participation is monolingual and bi-lingual information retrieval tasks done on the German Indexing and Retrieval Testdatabase (GIRT) at the Cross-Language Evaluation Forum (CLEF) 2004. We used a commercial morphological analyzer to decompound words and parallel corpora to retrieve bi-lingual information. While monolingual information retrieval was improved by using the analyzer, bi-lingual information retrieval still has room for improvement.
