Toward the Gateway Thesaurus System for Safety Research : For efficient accessing to safety information from a large number of databases

Abstract

　The issue of safety has been widely studied in numerous fields, such as occupational safety, traffic safety, environmental problems, chemical safety, drug safety, and so on. It is therefore necessary to retrieve data from a large number of databases in these fields in order to collect safety information in interdisciplinary fields. However, it is difficult to comprehensively gather safety information because of difference between keyword system maintained by each database.
　The Gateway thesaurus system for safety research has been under developing, in order to innovationally improve the efficiency of retrieval from a number of online databases with respect to safety issues. The system is constructed by two components, I.e. the knowledge base and the user interface. This paper describes the design concepts and outline of these systems.
