  2. Plan • Context • Proposal for an interface terminology with two basic resources • Bridging concepts and lemma’s by two methods • Implementation • More Context (Linked Data Publishing) • Conclusion

  3. Context • Health care professionals experience difficulties • In the correct medical registration of clinical work • In the efficient searching for answers to clinical questions • These difficulties arise often from • a deficient interface between human and machine language • Terminological solutions are often naive • Overwhelming or restricting too much the collections of concepts • Not addressing local, cultural differences between vocabularies

  4. Proposal for an interface terminology with two basic resources 1. A conceptual reference interface terminology • Multidisciplinary, multilingual • Restricted to reference concepts • Linked to international nomenclatures, thesauri, classifications and ontologies 2. A series of specific, monolingual end-user lexicons • Bridged to the reference terminology • Connected to rich linguistic corpuses for NLP

  5. Bridging concepts and lemma’s by two methods 1. A bridge between a concept from the Reference Terminology and one sense of a lemma from a Lexicon • Preserves conceptual integrity • Language independent 2. Alignment of the lexical representation of a concept in the reference terminology (in a given language) with the corresponding lemma in a lexicon (of that language) • Language dependent

  6. Implementation END USER LEXICON • LMF / ISO 24613 • Datacategories / ISO 12620 • Guidelines for linking LMF → TMF • Multiple senses • Connected to NLP-applications Reference Terminology • TMF / ISO 16642 • Data Categories / ISO 12620 • TML in RelaxNG • 1 preferred lexical repre-sentation for 1 concept • Links at the conceptual level with external semantic resources (SNOMED-CT, MeSH, ICPC, etc.)

  7. End user lexicon in LMF Reference terminology in TMF Lexicon model under development Terminological model developed

  8. External reference resources External reference resources Thesauri Nomenclatures Classifications Ontologies End user Lexicon In language 1 Linguistic corpus In Language 1 Multilingual Reference terminology Linguistic corpus In Language 2 End user Lexicon In language 2 Linguistic corpus In Language N End user Lexicon In language N NLP connections Bridging LMF / TMF Conceptual Linking

  9. External reference resources Interface terminology External reference resources Thesauri Nomenclatures Classifications Ontologies End user Lexicon In language 1 Linguistic corpus In Language 1 Multilingual Reference terminology Linguistic corpus In Language 2 End user Lexicon In language 2 Linguistic corpus In Language N End user Lexicon In language N NLP connections Bridging LMF / TMF Conceptual Linking

  10. More context (Linked Data Publishing) • Linked Data as the horizon • Technology stack built on the (Semantic) Web principles to link data on the Web in addition to pages/fragments • Useful for the implementation of: • Conceptual Linking to external formal systems • Bridging LMF/TMF-compliant resources within the Interface Terminology • Connecting to Linguistic Corpuses for NLP • All these relationships are qualified (levels of equivalency, narrower, broader meaning, ...)

  11. Conclusion • Interface Terminology as a dual resource • Reference Terminology & Monolingual Lexicons • No new ontology created • Three pillars • ISO Standards for multilingual terminologies • ISO Standards for lexicons • Linked Data publishing • Work under review by Belgian Government Health department (Working Group on semantic interoperability) • Deadline for the implementation of the Reference Terminology - Mid-2012
