Although a lot of researchers have pointed out the signicance of functional representation, the general relations between function and behavior is not fully understood yet. We consider the knowledge of each component in a system as consisting of two elements. One is a necessary and sucient information for simulation of the component which we call behavior.(More)
Ten years have passed since the concept of the semantic web was proposed by Tim Berners-Lee. For these years, basic technologies for them such as RDF(S) and OWL were published. As a result, many systems using semantic technologies have been developed. Some of them are not prototype systems for researches but real systems for practical use. The authors(More)
This paper discusses ontology mapping between two taxonomies of functions of artifacts for the engineering knowledge management. The mapping is of two ways and has been manually established with deep semantic analysis based on a reference ontology of function for bridging the ontological gaps between the taxonomies. We report on the successful results(More)
This paper presents a new parsing algorithm, BTH, which is capable of efficiently parsing a keyword lattice that contains a large number of false alarms. The BTH parser runs without unfolding the given keyword lattice, and thus it can efficiently obtain a set of word sequences acceptable to the given grammar as the parser result. The algorithm has been(More)
Growth in the mobile internet services industry has seen a marked increase in the number of mobile internet services provided, and this has made proper structuring and organization of the services difficult. Present methods of service provision have proven insufficient to guide users efficiently to the services they need. To solve this problem, a(More)
This paper introduces a new tool for supporting multilingual communication between speakers of different languages. Conventional tools such as electronic dictionaries enable users to communicate basic intentions to others, but are often insufficient to help understand replies. The input of a Japanese sentence in the proposed tool not only produces a(More)
