Security and privacy are the inherent problems in RFID communications. There are several protocols have been proposed to overcome those problems. Hash chain is commonly employed by the protocols to improve security and privacy for RFID authentication. Although the protocols able to provide specific solution for RFID security and privacy problems, they fail to provide integrated solution. This article...
The increasing body of distributed and heterogeneous information and the autonomous, heterogeneous and dynamic nature of information resources are important issues hindering effective and efficient data access, retrieval and knowledge sharing. The importance of ontologies has been recognised within the biomedical domain and work has begun on developing and sharing biomedical ontologies. In this paper,...
Ontologies and controlled vocabularies are being established by many groups to provide roadmaps through the confused mass of data currently being generated from increasingly large-scale experimental biological experiments. The world of protein chemistry is no exception to this rule, with protein ontology (PO) having lead the field by providing a framework in which individual molecules and complexes...
The goal of this paper is to survey existing biomedical ontologies and their developments in 2007. This paper discusses features of biomedical ontologies that allow true information integration in biomedical domain. The paper is compilation of several biomedical ontologies like gene ontology, protein ontology, etc. that have developed serving primarily the purposes of information extraction from on-line...
In this paper, we introduce the issues and solutions of using OWL ontology to model extra restriction on dasiaPropertiespsila of dasiaClassespsila that are not provided by OWL specifications and to represent associations amongst dasiaPropertiespsila other than dasiaClassespsila. Two specific types of knowledge that cannot be modeled directly using OWL DL elements are identified and presented. Firstly...
Todaypsilas e-businesses rely heavily on trust and reputation systems. These systems are key indicators for businesses performance. Businesses that interact with each other for their business needs form a digital business ecosystem (DBE). Members of DBE need to know the trust and reputation value of each other before the start of business interactions. The feedback mechanism is needed so that members...
