Abstract:
Linguistic Variables play a key role in the Computing withWords paradigm and in general in representing and managing vague knowledge. They are strongly related to Fuzzy Set Theory since the semantic of linguistic variables is given through fuzzy sets. In order to deal with structured vague information, it is thus fundamental to integrate ontologies and related instruments with fuzzy capabilities. Several approaches are known in literature that introduce fuzzy ontology languages, fuzzy reasoners and editor plug-ins to represent them. However, none directly deals with the problem of representing linguistic variables. In the present paper, we introduce a Protégé Plugin developed to define linguistic variables in ontologies. The plug-in is based on OWL2 and on a lite version of its fuzzy extension.
