Geosemantic Approach To Detect Inconsistency In Geospatial Web Services Metadata

The validation of the metadata associated with Geospatial Web Services is one of the main problems related to the preservation of the information in the Geospatial Web Service Catalogs. This work describes a new automatic method for detecting outliers in metadata registers in order to ensure coherence of the spatial description contained in metadata. The method is based on the combination of spatial clustering techniques and geographical statistical analysis. The results allow showing the need for systems to detect inconsistencies in order to validate the semantic integrity of geospatial metadata resources.
