Enhancing Semantic Interoperability: Insights from SALUS Advisory Board Meeting

The SALUS Advisory Board Meeting held on January 17, 2013, focused on advances in semantic interoperability. It emphasized the importance of formalizing not just terminology, but also the relationships between concepts and their context. A critical discussion revolved around constraining semantics to limit interpretations, an essential factor since context can vary greatly for people but remains static for computers. This meeting explored the Semantic Interoperability Platform (SIP) which proposes to establish a common ontology and facilitate uniform querying of data across disparate systems.

  2. Semantic Interoperability • Formalization of more then ‘just’ terminology, but also the relations between concepts and the context • Constraining the semantics = limiting possible interpretations • People can interpret according to the context, computers don’t • This summer I travelled to Java • This software module is written in Java • My preferred brand of coffee is Java

  3. IntroductionThe Semantic Interoperability Platform (SIP) • A simple thing (?)  • Put a semantic layer on top if any resource • Define a common ontology (or a system to mediate between ontologies) • Query data as if everything behaves as one virtual system Virtual and consolidated information source Semantic Interoperability Platform Semantic layer Semantic layer Semantic layer Semantic layer Semantic layer Information source Information source Information source Information source Information source
