In this book, we propose two new formal models of ontology with object membership and object typicality, a first model and a better model. These models are based on the theories in cognitive psychology and fuzzy set theory. They extend current ontologies to reflect object typicality and object membership in concepts. Besides, we formalize object typicality in context-aware ontologies based on property importance. In addition, in order to handle concepts defined by property importance and property priority, we extend our better model to handle object membership in concepts with weighted properties and prioritized properties. Based on the idea of object typicality from cognitive psychology, we study recommendation systems from new perspectives and propose some novel recommendation approaches.
