The frame-based spatial knowledge representation

A representation scheme for spatial data is proposed for image information systems (IIS). This scheme uses a frame-like structure as its abstract data type. The knowledge of image data and their spatial and semantic relationships are represented by frames. The control strategy, using approximate matching and rules, can reason the spatial relationships and give the semantic interpretation of image data. The incorporation of techniques from inexact reasoning allows IIS to more closely model realistic situations, thus making them acceptable to IIS practitioners.<
