Abstrakt: Providers of communication services must be able to respond rapidly to the growing diversity of their customers' service needs as society becomes more dependent on information technologies. This responsiveness will be enhanced if the users themselves can define their service requirements, ideally using natural language. The problem with natural language expressions is their diversity, due to the various viewpoints from which they are written. Thus, we need a means of understanding the semantics of these diverse expressions. In the study outlined here, aimed at understanding the concepts in communication service requirements written in natural language, the authors first clarify the factors causing diversity of expression. These are found to be combinations of three intersecting viewpoints, namely: the interfaces between the network, terminals, and users; the viewpoint from both sides of each interface; and the logical/physical information viewpoint. Next, the target domain of communication services is modeled from the standpoints of operation procedures and functions, communication service concepts are systematized in terms of these models, and a communication service ontology is constructed. Then a semantic recognition method is proposed based on a mapping between concepts and expressions. The effectiveness of the methodology is demonstrated by converting natural language descriptions to formal language specifications. © 1997 Scripta Technica, Inc.
