Automatic methods for mapping Biomedical terminologies in a Health Multi-Terminology Portal

Terminology mapping is an important and crucial task to improve semantic interoperability between health care applications and resources. In 2009, CISMeF created a Health Multi-Terminological Portal (HMTP) to search concepts among all the health terminologies available in French (or in English and translated in French) included in this portal and to browse it dynamically. To map terminologies in the HMTP, two methods are used: (1) conceptual method which exploits various features of the UMLS, (2) lexical method based on natural language processing in French and English. A total of 199,786 mappings were performed between at least two French terms using conceptual method, whereas 266,139 mappings were performed using lexical methods. These mappings were all integrated in the HMTP developed by CISMeF. Conceptual and lexical methods were used to translate some English terminologies into French such as MEDLINEPlus, FMA and SNOMED CT.
