This paper deals with the problem of ontology generation. Ontology plays an important role in knowledge representation, and it is an artifact describing a certain reality with specific vocabulary. Recently many researchers have realized that folksonomy is a potential knowledge source for generating ontologies. Although some results have already been reported on generating ontologies from folksonomies,...
Ontology is the basis component of the Semantic Web. Since constructing ontologies is a time consuming job for domain experts, many researches are conducted on automatic extraction of ontologies from texts. As the development of folksonomy, more and more researchers have realized that folksonomy is a better knowledge source for constructing ontologies than texts. Although some works have already been...
According to the studies of cognitive psychology, object typicality plays an important role in concept representation in human cognitive process. However, computational ontologies cannot reflect the typicality of objects in concepts. Besides, context is important in measuring object typicality. In this paper, we present a formal model of context-aware ontology with multi-prototype concept and object...
