Instantiation of the multi-viewpoints ontology from a resource

ABSTRACT

We are interested in the acquisition of instances of concepts from a text resource. These concepts are defined in the multi-viewpoints ontology. The multi-viewpoints ontology allows giving several definitions of a single concept. Each definition is guaranteed by a viewpoint. In the multi-viewpoints ontology, a single individual is an instance of several concepts. That is, which we call the multi-instantiations. The acquisition of the multi-instantiations from a resource requires alignment between the resource elements and the multi-viewpoints ontology elements. The structure of the multi-viewpoints ontology and the semantic constraints of the multi-viewpoints ontology concepts differ from the classical ontology’s. For that, the existing processes, which allow aligning the resource element with a classical ontological concept, cannot align the resource element with a multi-viewpoints ontology concept. Thus, we propose a new process, which offers a possibility to align resource elements with multi-viewpoints ontology concepts in order to acquire the multi-instantiations. The obtained multi-instantiations will be represented in the Multi-Viewpoints Ontology Language, in order to be integrated into the multi-viewpoints ontology.
