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...
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...
Nowadays, the research of crawlers moves closer to the semantic web, along with the appearance of increasing XML/RDF/OWL files and the rapid development of ontology mark-up languages. As an emerging concept, metadata abstraction crawlers are a series of crawlers that aim to abstract metadata from normal HTML documents, based on various semantic Web technologies. In this paper, we make a general survey...
Component retrieval/discovery is a well-established research direction in Software Engineering. With the surge of Service-Oriented Architecture (SOA), service discovery has become increasingly crucial. However, the public UDDI Business Registry - the primary service discovery mechanism over the Internet - has been shut down permanently since 2006. Moreover, keyword-based service discovery is insufficient...
The research with regards to digital ecosystems emerged in the end of last century, and has developed in this century. Due to its immaturity, some fields within it are deemed to be blank. This research proposes to fill one of the blanks in the digital ecosystems research. By analyzing the issues in the current research, we propose to develop a semantic search engine, with the purpose of querying services...
In this paper, we make a survey over the primary literature regarding semantic search technologies. By classifying the literature into six main categories, we review their characteristics respectively. In addition, the issues within the reviewed semantic search methods and engines are analysed and concluded based on four perspectives.
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...
Ontologies are the foundation of the semantic Web (SW) and one of the keys necessary to its success. Conversely, e-Science domains are usually characterized by heterogeneous semistructured data models and formats. In recent years, building ontologies are gaining momentum in the e-science domains to provide explanatory semantics in an agreed, yet shared encodings. Conversely, ontology views hold the...
Digital ecosystems transcend the traditional, rigorously defined, collaborative environments from centralised, distributed or hybrid models into an open, flexible, domain cluster, demand-driven, interactive environment. A digital ecosystem is a newly networked architecture and collaborative environment that addresses the weakness of client-server, peer-to-peer, grid, and Web services. In this paper...
