The word ontology refers to the hierarchical structure of entities and their relationships. The entities are nodes and each node is dominated by their parent node in the hierarchical structure. The nodes are related by semantic and lexical relations such as synonymy, homonymy, meronymy, antonymy, etc. Hierarchical structure is created for different types of semantic domains. The top domains are entities,...
The development of domain ontology is important in building a list of vocabulary whereas the process of sharing and reusing this knowledge management can be accomplished easily. This paper presents the challenges that arise in the ontology development area by focusing on one domain concept. Domain concept here can be transversed from different disciplines, such as agricultural, medicine, human-anatomy,...
While applying attribute based access control in dynamic open multi-domain environments, an important critical problem is how to make these domains know each other about the semantics of attributes defined by them. Towards this problem, a novel method of attribute matching is proposed in this paper. This matching is based on other domains' knowledges of the specific concept relationship. The knowledge...
The objective of knowledge integration is to promote knowledge collection, sharing and retrieval in distributed and heterogeneous environment. Our workgroup develops a domain-oriented model for knowledge integration in distributed heterogeneous environment such as semantic grid, which promises better access to relevant knowledge by producing a global domain ontology that is used for establishing semantic...
