We have developed a query and reasoning system using concept expressions in description logic that returns answers from RDF data. In addition to the system, we have implemented a fast RDF store system for reasoning and searching in large RDF datasets. In order for users to search knowledge, we have proposed a method that translates keywords and Japanese sentences into RDF queries. We have designed algorithms for machine learning and data mining that infer knowledge from users' ambiguous interests.
