The document discusses the challenges of semantics, interoperability, and integration within European customs and excise systems, highlighting the involvement of numerous European and international organizations. It identifies key issues such as the lack of structured standard messages for risk-related information and the complexities involved in database interoperability and ontology integration. The need for a rigorous approach to define risk-related entities and semantic identification is emphasized to improve customs processes related to public safety and health.

- 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. 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. 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. 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
