Semantic Constraint based on Frame Combination
基于框架复合的语义限定

It is one of the important developing directions of GIS(Geographic Information System) to integrate theories and technologies in the field of AI(Artificial Intelligence) with GIS to design the thematic analysis model in GIS application.Under such circumstances,problems of representation for the GIS thematic knowledge were discussed in this paper.An enhanced frame representation and the idea of frame combination were presented,and then the frame combination operation was put forward to perform semantic constraint on the concept and to obtain more accurate meaning of the concept.
