Abstract:

Geospatial semantic web has become a research hotspot. The uncertainty is an intrinsic property of spatial information. There has been no research to combine geospatial semantic web and uncertainty. The Fuzzy Spatial Description Logic (FSDL) is proposed in this study, which is based on spatial reasoning and fuzzy logic. It can be treated as a basic theory for uncertainty reasoning supported geospatial semantic web and spatial ontologies. FSDL augments the following features to classical description logic: the complex role forming predicate for describing spatial relation, the syntax and semantics for fuzzy concept and roles. The tableau algorithm and the soundness and completeness proofs are given. Finally fuzzy RCC5 relation is defined based on FSDL.

Key words: artificial intelligence, description logic, qualitative spatial reasoning, fuzzy logic, region connection calculus
