摘要
The Case Hierarchy model describes the case system of unconstrained natural language and the ways in which the case system is specialized in a restricted domain. It is the basis of a procedure for the analysis of such restricted domains. The resulting representations can be used to determine the case related requirements of a case grammar based natural language interface for the domain, either for initial development or for adapting an existing interface to a new domain. This paper briefly describes the Case Hierarchy and presents the results of a feasibility study that examined the utility of the Case Hierarchy and the Case Hierarchy Tool, an intelligent editor that supports the domain analysis process. The study showed that the representations and procedures do provide some constraint and guidance for an otherwise unconstrained task. © 1990.
