Abstract In this paper, I discuss how to distinguish between ontological categories and ordinary categories. Using an argument against van Inwagen’s proposed account of what makes a category as springboard, argue that if are modally robust, then need be understood hyperintensionally. This conclusion opens up wide range new ways define ‘ontological category’, close by briefly outlining one such ...

Ontologies are conceptualizations of some domain, defining its concepts and their relationships. An interesting question is how do we relate the ontological concepts to the general vocabulary of the domain? In this paper we present the concept of ontological profiles, what they are, how they are constructed, and how they may be used. We propose that the ontological profile is a link between the...

With the rapid development of remote sensing platform and sensor technique, the amount of satellite images has frequently increased. In order to analyze, manage and retrieve spatial information, several techniques are used to improve the quality of retrieval systems and to perform semantic in the retrieval process. In this paper, we propose an ontology-based approach for semantic retrieving of ...

Modern portfolio theory is based on the relationship between risk and return and in this paper, specific uncertainty conditions are introduced as ambiguity which affects the asset pricing. Also, the relationship between risk, ambiguity and return is examined. First, ambiguity is estimated by the means of three-variable and main component method, trading volume, ask-bid spread, error of earnings...

Knowledge management systems have often been considered as a means for sharing knowledge among communities of users. The key of success of knowledge sharing in the field of agriculture is using sharing agreed terminologies such as ontological knowledge especially in multilingual aspects. This paper proposes a workbench for collaborative ontological knowledge construction and maintenance with au...

As is clear in the 2008 report of the President’s Council on Bioethics, the brain death debate is plagued by ambiguity in the use of such terms as “integration” and “wholeness.” Addressing this problem, I offer a plausible ontological account of organismal unity by drawing on the work of Hoffman and Rosenkrantz. I then apply that account to the case of brain death and conclude that a brai-dead ...
