The health service ecosystem is a sub domain of the service ecosystem, which is an ecological view of the health service domain. Due to the importance and the speciality of health services, service consumers have rigorous requirements regarding the efficiency of health service search engines. However, as most health service consumers do not have enough domain knowledge, their service queries are sometimes...
With the rapid growth of the amount of information available in the Web, webpage classification technologies are widely employed by many search engines in order to formulate user queries and make users' search tasks easier. Knowledge grid is a new form of Web environment, in which a resource space model is employed in order to classify available semantic documents within the Web environment. However,...
Digital Ecosystem is defined as ldquoan open, loosely coupled, domain clustered, demand-driven, self-organizing and agent-based environment, in which each species is proactive and responsive for its own benefit and profitrdquo [1]. Species in the Digital Ecosystem can play dual roles, which are service requester (client) service provider (server). A service provider enters the Digital Ecosystem by...
Ontology is a technology for conceptualizing specific domain knowledge, which can provide machine-readable definitions to the severed domain. Therefore, ontology can be utilized to enhance the performance of focused crawlers, by precisely defining the crawling boundary. In this paper, we will exhibit a conceptual framework of an ontology-based focused crawler serving in the domain of transport services...
Crawlers are software which can traverse the Internet and retrieve Webpages by hyperlinks. In the face of the inundant spam Websites, traditional Web crawlers cannot function well to solve this problem. Semantic focused crawlers utilize semantic web technologies to analyze the semantics of hyperlinks and Web documents. This paper briefly reviews the recent studies on one category of semantic focused...
This paper aims to present software engineering ontology as software engineering knowledge representation for a multi-site software development. It will not only facilitate the capturing of software engineering knowledge but also enhance the sharing of software engineering knowledge across geographically multiple software development sites. The software engineering ontology assists in defining information...
Transport is a crucial component in logistics, which joints each activity in the logistics chain. The performance of logistics heavily relies on the efficiency of transport services. However, until now there has not been a clear definition about transport services. Moreover, along with the rapid rise of fuel prices, the input-output ratio of transport has been trapped in an unreasonable situation,...
Negotiation is defined as two or more agents making agreement on the common interests, which provides an efficient approach for companies to gain business intelligence from suppliers and customers. Current negotiation research focuses on automatically stimulating negotiation behaviors among agents. Ontology, as a modeling technology in semantic web, is regarded as an effective tool to improve the...
In this paper, we propose a knowledge sharing platform based on the technology of ontology and agent, in order to solve the issues in the knowledge sharing activities within organizations. Based on the analysis of literature, the issues within current organizational knowledge sharing activities and knowledge sharing technologies are explored. By means of the literature analysis, we present a new definition...
Risk is omnipresent in all the interactions that we carry out. Quantifying and making risk-based assessments and decisions is very important especially in the case of business interactions. However in the existing literature there is no ontological manifestation of risk and its related concepts. In this paper, we propose an ontological manifestation of risk. Subsequently it is extended to derive an...
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...
Privacy is becoming increasingly important due to the advent of e-commerce. E-commerce applications frequently require customers to divulge many personal details about themselves that must be protected carefully in accordance with privacy principles and regulations. Here, the authors define a privacy ontology to support the provision of privacy and help derive the level of privacy associated with...
Biomedical knowledge of proteomics domain is represented in the protein ontology, whose instantiations, which are undergoing evolution, need a good management and maintenance system. Protein ontology instantiations signify information about proteins that is shared and has evolved to reflect development in protein ontology project and proteomics domain itself. In this paper we explore the development...
Protege is a set of open-source ontology design software developed in Stanford Medical Informatics. SPARQL (protocol and RDF query language) is recommended by W3C, to represent the RDF (resource description framework) graph - a set of triples that consist of a subject, a predicate and an object as the basic expression of data stored in OWL- based knowledge base. In this paper, we propose an ontology-based...
Digital ecosystem, as a neoteric terminology, has emerged along with the appearance of Business Ecosystem which is a form of naturally existing business network of small and medium enterprises. However, few researches have been found in the field of defining digital ecosystem. In this paper, by means of ontology technology as our research methodology, we propose to develop a conceptual model for digital...
Image retrieval (IR) is one of the most exciting and fastest growing research domains in the field of multimedia technology. And in the industrial ecosystems, images of products, activities, marketing materials etc are needed to be managed and fetched in an efficient way to support and facilitate business processes. Current techniques for IR including keyword based, content based and ontology based...
