Déclaration de conflit d’ interêt Je suis médecin généraliste, pratiquant dans la ville de Gand, Belgique Je suis pharmacologue clinique, professeur à l’ Université de Gand Je travaille sur des projets Européens (FP7 et H2020), dans le cadre :
• un service universitaire d’ informatique médicale (RAMIT) • une association Européenne de marchands de logiciels médicaux (EuroRec)

“Investigation starts with a problem” Karl Popper International reference terminologies are in English. Health care worker have the fundamental right to work, document, practice continuing education, search for point of care EBM information IN THEIR MOTHER TONGUE LANGUAGE. Evidence shows that it provides a more efficient information flow. Many E-health engineers and medical informaticians speak of semantic interoperability, as if English is the only language in the world.
Objective
Provide a hybrid healthcare interface terminology capable of automatically linking patients’ and physicians’ medical words to the corresponding concept(s) in international classifications
That includes:
1. A conceptual reference terminology
– Multidisciplinary, multilingual – Restricted to reference concepts – Linked to international nomenclatures, thesauri, classifications, ontologies
2. A series of specific end-user lexicons
– One for each language – Bridged to the reference terminology – Connected to rich linguistic corpora for NLP
‘‘Systematic collection of healthcare-related phrases (terms) to support clinicians’ entries of patient-related information into computer programs …”

The Lemon core structure of a lexical terminology
The ISO-Norm LMF : Lexical Markup Framework (ISO 24613)
The ISO-Norm TMF : Terminological Markup Framework (ISO 16642)
Lemon/LMF-based End-user Lexicons • ISO 24613 - Language Markup Framework (LMF)
as a Requirement for the Lexicon • Use of the Lemon model (LExicon Model for
ONtologies) because: – Based on LMF – RDF-native model – Easy to link to data category registries (ISOcat) – The sense of a lexical entry can be defined by a reference to an
external resource (E.g. our TMF-based resource) – More powerful and less verbose than the LMF model – http://lemon-model.net/ (McCrae et al.)
