Abstract

With the current emergence of Cognitive Sciences and the development of Knowledge Management applications in Social and Human Sciences, Subjective Knowledge becomes an unavoidable subject and a real challenge, which must be integrated and developed in Ontology Engineering and Ontology-based Information Retrieval. This paper introduces a new approach dedicated to the Personalization of a Domain Ontology. Inspired by works in Cognitive Psychology, our work is based on a process which aims at capturing the user-sensitive degree of truth of the categorisation process, that is the one which is really perceived by the end-user. Practically, this process consists in decorating the Specialisation/Generalisation links (i.e. the ISA links) of the hierarchy of concepts with a specific gradient. As this gradient is defined according to the three aspects of the semiotic triangle (i.e. intensional, extensional and expressional dimension), we call it Semiotic-based Prototypicality Gradient. It enrichs the initial formal semantics of an ontology by adding a pragmatics defined according to a context of use which depends on parameters like culture, educational background and/or emotional context of the end-user.
