ABSTRACT

Finding articles providing answers to specific clinical questions is greatly facilitated by the availability of indexed Medline abstracts using the Pubmed search engine. Nonetheless, the large number of references sometimes requires a time-consuming review of multiple abstracts. In order to streamline the search process, we have created a tool facilitating the search and review of these abstracts. We present here this tool named "Méta-analyse".

ABSTRACT

The goal of this article is to present to the radiologist the different theories of the sign and their consequences for sign representation in computer systems. All the theories of the sign are presented, but the most relevant are highlighted in order to explain the great modeling systems currently in use (such as DICOM-SR or the UMLS). The constructivist approach of the notion of disease, the semiosis process, which starting from signs produces new signs, and the structuralist analysis of sign through language are emphasized. The purpose of this analysis is to end up with a consensual representation of the sign that can be understood by human beings and processed by machines. Such a representation, also known as an ontology, is based on a semantic organization of language, thus allowing medicine to become a truly scientific discipline. It aims at disambiguating the symbols given to machines, which will help us in our reasoning.
