Integration Method of Geospatial Services TaxonomiesBased on Formal Concept Analysis

Owing to the semantic heterogeneity of different taxonomies,it is difficult to realize integra-tion and composition of services managed by them.This paper puts forward an integration method forgeospatial services taxonomies based on formal concept analysis.Heterogeneous taxonomies are inte-grated into a taxonomy,mappings of classes in different taxonomies are established,integration andcomposition of services are achieved.Three different taxonomies for geospatial services are used todemonstrate that the method is appropriate.
