Distributed Ontology for the Needs of Disabled People

Caroline Wintergerst, Guilaine Talens

Abstract

In French society, much help is provided to people. In the particular case of disabled people, it is quite difficult to deal with all the different information coming from heterogeneous contexts. Such different knowledge cannot be directly integrated, so we propose to build ontologies for each aspect. Three ontologies are built, each from different existing sources (thesaurus, ontology, ...). Disability ontology includes the medical and social domain. Service ontology represents generic and local services. Individual needs ontology allows the individual file description and the link with the other ontologies. Each ontology will cooperate with the others. Then, the cooperation of these distributed ontologies must solve the problems of semantic conflicts. A framework is proposed to build each ontology and also to manage ontology collaboration.To ensure the representation of the guidance interactive process, we model a workflow to follow an individual file through its successive steps. This allows better long term assistance monitoring and proves the necessity for evolutive knowledge representation like ontologies.
