Ontological Re-classification of Individuals: A Multi-viewpoints Approach

摘要

A multi-viewpoints ontology confers to the same universe of discourse, several partial descriptions, where each one is relative to a particular viewpoint. Moreover, these partial descriptions share at global level, ontological elements and semantic bridges constituent a consensus between the various viewpoints. In this paper, we define, firstly, a multi-viewpoints knowledge model based on viewpoint and ontology notions. The multi-viewpoints knowledge model is used to formalize the multi-viewpoints ontology in description logics. Then, based on developed model, we propose a process for the relocation of an individual in a multi-viewpoints ontology. The Individuals relocation concerns the reclassification of an individual, already classified, who sees its data change. The reclassification is necessary when the knowledge of the individual evolves. This evolution may be the result of an enrichment (adding knowledge to the individual), a impoverishment (removing knowledge), and/or modification (changing knowledge).
