自然言語空間記述からの空間関係についての知識の逐次獲得

抄録

A natural language processing technique and reasoning techniques are united to create a computational model representing the process of updating and maintaining knowledge about spatial relations. Assumptions and a method of incremental knowledge acquisition from a natural language discourse are proposed An interactive system that understands sentences describing spatial relations is implemented. The system determines the reference of anaphoric expression from the literal meaning of the input and the implicit meaning derived from the context. The topological representations of the spatial relations that satisfies every sentence in a discourse are generated from well-formed descriptions composing the discourse.
