階層関係自動抽出法の改善に関する検討

　The global flow of information is being developed at unprecedented speed. Advanced utilizations of contents of information are required. In order to realize such sophisticated utilization, it is necessary to understand meaning and characteristics of information. Therefore, the structuralization is required to represent various semantic relationships among information. In order to satisfy such requirement, we proposed a new representation of such structure, and made a system for self-organized knowledge resources based on semantic relationships and an application using conceptual structures.
　However, this system is a prototype and cannot make enough conceptual structures to realize sophisticated utilization. Semantic relationships among knowledge resources must be correct and appropriate to objectives of applications. The main reason is that advanced utilization consists of navigations based on semantic relationships. This paper reports improvements at the method of an automatic extraction of hierarchical relationships which called SS-KWEIC.
