EDF2014: Talk of Ioannis Kotsiopoulos, European Dynamics: Semantics – Interoperability – Integration: A multi-faceted problem

  3. 3. Semantics-Interoperability-Integration • Interoperability started early 2000 by TAXUD • Implemented though the exchange of structured messages between Member States applications via the private CCN/CSI network • Semantics are defined as part of complex functional and technical specifications • Currently at least four major functional areas are covered (e.g. transit, export, import etc) • Important areas such as risk analysis are not covered. Customs & Excise
  4. 4. Semantics-Interoperability-Integration • XML & EDIFACT messages defined by TAXUD • Although message formats are well-defined, semantics are only indirectly defined via separate documents • e.g. same entities appear under different names and information structures • Semantics today are incorporated in individual application logics developed by the Member States • Despite those problems CCN/CSI does perform its basic function Common Communication Network (CCN/CSI) Interoperability
  5. 5. Semantics-Interoperability-Integration Risk analysis and fraud detection Interchange of risk-related information is critical for customs processes as it is related to public safety and health So far there have been no structured standard messages for the exchange of risk-related information at semantic level:  What is a “suspicious trader”, “a suspicious route”, etc?  Risk entities: financial and statistical information  No behavioral models Only abstract common risk criteria have been defined The need:  Definition of risk-related entities  Semantic identification by machines
  6. 6. Semantics-Interoperability-Integration Is semantic interoperability and integration difficult? • YES! • Database interoperability, cross-database search and integration of web services: Ontologies: formally logical axioms that relate predicates of interest  a higher level of abstraction for data modelling  data export, translation, queries, unification across independently developed database designs (logical or physical) • However: when data integration is sought limitations emerge*: • Datasets with semantics given by different ontologies require integration of ontologies (ontology mapping, merging, top-level vocabularies, etc) • Integration of ontologies: integration of logics in which they are expressed and of schemas describing structure in different languages and different underlying data models (relational, object-oriented, etc) • Need for rigorous foundations not tied to any specific representational (e.g. category theory) or logical formalism (e.g. theory of institutions) * http://epractice.eu/en/library/292976
