- Achieving interoperability in e-government services with two modes of semantic bridging: SRS and SWRL Saravanan Muthaiyah Larry Kerschberg Multidisciplinaria (Ciencias Naturales y Exactas) EDI XML Semantic Ontology Syntactic Data heterogeneity in the public sector is a serious problem and remains to be a key issue as differentnaming conventions are used to represent similar data labels. The e-government effort in many countries hasprovided a platform for government entities and their business partners to exchange data through InformationCommunication Technologies (ICT) and standards such as RosettaNet (B2B data exchange standard),EDIFACT (Electronic Data Interchange for Administration, Commerce, and Transport), XML (Extensible MarkupLanguage) and EDI (Electronic Data Interchange). However, e-government efforts have not really resolveddata heterogeneity problems significantly due to limitation of these standards. One such limitation is the inabilityof data inheritance. In order to solve this problem with emphasis on Service Oriented Architectures (SOA) andWeb Services, a semantically enriched web service for the public sector is needed. Thus we propose anontology-based solution which allows data inheritance and polymorphism. This goal of this paper is to showhow heterogeneous e-government documents can be semantically matched. We propose a shared hierarchicalknowledge repository approach and a detailed process methodology for semantic mediation. A two-partsemantic mediation approach using SRS (Semantic Relatedness Scores) and SWRL (Semantic Web RuleLanguage) is highlighted. Both measures are complimentary and provide the semantics necessary for resolvingschema heterogeneity. Our approach incorporates a rule-based engine that reads and executes SWRL rules(i.e. RacerPro). We also adopted several tools for proof-of-concept such as Protégé (i.e. ontology editor) andJESS (Java Expert Shell System) 2008 artículo científico 0718-1876 https://www.redalyc.org/articulo.oa?id=96530305 en http://www.redalyc.org/revista.oa?id=965 Journal of Theoretical and Applied Electronic Commerce Research application/pdf Universidad de Talca Journal of Theoretical and Applied Electronic Commerce Research (Chile) Num.3 Vol.3
