Use of geo-ontology matching to measure the degree of interoperability
Interoperability is a key concern in geospatial domain. Approaches based on Geo-ontology which represents the semantics of the geospatial information are currently popular. However, there still remains the problem of reconciliation of different geo-ontological representations. Hence, many geo-ontology matching systems have been developed to harmonize and integrate various information sources for resolving the heterogeneity and achieve interoperability. However, deriving the degree of interoperability between two information sources is a challenge. Measuring the degree of interoperability helps in understanding, the readiness or the amenability to communicate across similar representations, thus identifying those information sources (out of many similar ones) that can be integrated. This paper describes a Geo-ontology matching framework to measure the degree of interoperability.
