From Classifications and Coding systems to Ontology: the role of a CEN standard: The categorial structure

چکیده
The presentation recalls the limits of terminologies of 2 coding systems for surgical interventions: the French CCAM and the Australian international ICHI as assessed by Galen ontology driven tools. Such an ontology associated with natural language processing allows to analyse inconsistencies and ambiguities of natural language expressions when considering the reality of surgical interventions .On the other hand there is an increasing need for international comparisons and cooperation across the most advanced and less developed countries for instance for Electronic Health Record safety , trans border migration of population, case mix and procedure payment et . As no reasonable person is proposing to standardise the linguistic expressiveness of different health care professionals and of the citizens the European Standard Body CEN has developed since 1990 through is Technical committee 251 and its working group 2 an approach named Categorial structure which is presented here with the different application fields. The role of this tool is addressed in relation with ontology. It is proposed not as ontology but as a step to link biomedical terminology to ontology. Such a standard is an easy and provisional condition to evolve from functional to full semantic interoperability which needs a rigorous ontology.

Introduction: Electronic health record (EHR) is defined as digitally stored healthcare information about an individual's life time with the purpose of supporting continuity of care, education, and research. Major issue that needs to be addressed in order to accomplish with sharing and exchange is the development and use of content and structure standards in the EHR. Based on, this investigation...

Semantic interoperability (SIOp) is a major issue for health care systems having to share information across professionals, teams, legacies, countries, languages and citizens. The World Health Organisation (WHO) develops and updates a family of health care terminologies (ICD, ICF, ICHI and ICPS) and has embarked on an open web-based cooperation to revise ICD 11 using ontology driven tools. The ...
متن کاملStandards and Biomedical Terminologies: the CEN TC 251 and ISO TC 215 Categorial Structures. A step towards increased interoperability
Among different biomedical terminologies standardisation strategies the European Standard Body CEN TC 251 followed by the ISO TC 215 have stated that it was not possible to convince the different European or international member states using different national languages to agree on a reference clinical terminology or to standardise a detailed language independent biomedical ontology. Since 1990...
متن کاملThe CEN ISO Standard Categorial Structure as a Top-Level Set of Constraints for Ontology Disambiguation
Since 1990 CEN TC 251 and ISO TC 215 have developed an approach named Categorial Structure. It is a logic-based language that aims at standardising the upper level structure of a terminological model rather than agreeing on a reference clinical terminology or on a language-independent biomedical ontology. Since 2000 methods, tools and techniques based on upper level ontology and description log...
متن کاملAn Executive Approach Based On the Production of Fuzzy Ontology Using the Semantic Web Rule Language Method (SWRL)
Today, the need to deal with ambiguous information in semantic web languages is increasing. Ontology is an important part of the W3C standards for the semantic web, used to define a conceptual standard vocabulary for the exchange of data between systems, the provision of reusable databases, and the facilitation of collaboration across multiple systems. However, classical ontology is not enough ...
