Capturing a domain of discourse in an object-oriented class model and in a reference ontology leads to different results. On the one hand, modeling decisions for class models are motivated by pragmatic and efficiency-related choices because modeling decisions are motivated by different choices. However, information integration scenarios require a coexistence between reference ontologies and class...
The web size is increasing continuously. Chinese researchers have shown that web growth obeys the Moor's law and the Internet will double in size every 5.32 years. The more the Internet is growing; the more tendencies the people have to use the search engines. Moreover, since most of the commercial search engines are based on keyword indexing, there are many records in their result lists that are...
With the rapid development of computer technologies and medical industries, the sharing and exchanging of medical information has become increasingly important. A framework for integrating heterogeneous, diverse and various medical information systems based on Health Level 7(HL7), ontology and Web services is proposed in this paper. In the paper, we describe the framework architecture, module function,...
With the increase of the number of independent database applications, Large organizations are eager to an effective solution of heterogeneous and distributed databases integration. Ontology is defined as an explicit formal specification of a shared conceptualization. It can provide semantics through relations between concepts and can be widely used on heterogeneous data. This paper mainly discusses...
Compare with SOAP-based service that based on interfaces access pattern, RESTful web service is HTTP-based and use resource as the operation object. On the purpose of supporting RESTful in the enterprise information application, a Resource-oriented Information Supported Framework is constructed based on ontology construction and evolution. First, the initial ontology with relational pattern is extracted...
The communication between the teachers and students is very important in network education. Question-answering system can resolve the problem. This paper proposes a question answering platform in network education and then introduces the kernel module which is the answer extraction based on FAQ and ontology in detail. The paper describes the similarity algorithm between the student question and the...
Current many information retrieval methods are based on purely keywords for representing the user needs. One of the main problems with this method is that it does not formally capture the explicit meaning of a keywords query, and ignores the documents that may be different in content but related with them. To improve the precision of the information retrieval, this paper proposes a hybrid method for...
In order to satisfy various requirements of multi-tenants of Software as a Service (SaaS), the paper proposes a service-oriented business rule processing model (BRPM) by applying business rules in SaaS environment. Rule customization, rule storage and rule execution are three components of this model. Ontology is introduced and two feasible ways for two roles in SaaS are presented for dynamic rule...
The Avert-IT project (EU FP7) is an initiative to develop a system that can predict the onset of hypotensive events in patients over a feasible timescale (e.g. 15 mins) and allow clinicians to administer the appropriate treatment. To produce this system requires the additional development of a data collection platform, based at six leading clinical centres throughout Europe, with real-time integration...
Retrieving and integrating contents of different kinds is a complex task. Actually the web offers few examples of systems able to carry out such a task. This paper presents WikiArt, a system able to integrate three different kinds of information sources: a database, a wiki, and an ontology. All these three elements regard arts. Finally, WikiArt is able to generate automatically thematic paths to browse...
The Web has been designed for direct human processing, but the next-generation Web, named ??Semantic Web??, aims at machine-processible information. In recent years, only RDFS storage and query are considered because storage and query for other Semantic Web data modeling formalisms, especially OWL, are still an open research issue, and only a very small number of, furthermore incomplete, proposals...
The purpose of the present work was to create a computational framework for radiological registry and diagnosis, which, by means of a nonintrusive approach, allows the users freedom annotation while storing related information in a structured and standard format. To get this goal, this work started with the investigation of lexical and semantic domain of radiological texts, followed by the design...
In this paper, on the basis of constructing domain ontology database and designing meta-search engine, and relying on the reasoning mechanism of domain ontology and abundant internet sources, we propose the emergency domain ontology-based intelligent meta-search system and carried out the example verification. The results show that the model has great practical significance. The introduction of meta-search...
In manufacturing grid (MG), manufacturing service discovery and matching are related to the realization of the goal of manufacturing resource sharing. Because of lacking the support of a powerful semantic model, the methods and effects of service discovery and matching are still non-ideal, and affect the implementation of rapid, effective discovery and matching of the manufacturing service. On the...
This paper analyzed the Formal expression corresponding relationships between relational databases and OWL ontologies firstly, and then proposed technology of ontology automatic construction based on relational databases. The main steps and key links were discussed in detail, and then an ontology generator named OWLFROMDB was implemented, which can automatically convert a relational database to an...
A concept of semantic web service discovery search model is proposed. The definition, the semantic web service discovery search model (SWSDSM) unified with the semantic and the search engine technology, is proposed after the existing Web service discovery technology studied systematically and thoroughly. This model might search for and fuse the information in the UDDI registries, then provide for...
In this paper, an OntoCrawler based on the ontology-supported technique for webpage searching was proposed, in which only user entered some keywords would the system supported by domain ontology actively provide comparison and verification for those keywords so as to up-rise precision rate of webpage searching. This technique has practically been installed in Google and Yahoo search engines and furthermore...
Current searching works are common and essential in Web users. On the other hand, in the real world, the searching is the time-consuming works because of several searching to extract more exact and satisfied information. In this paper, we propose an Inference process to effectively extract control points based on the ontology. The ontology-based searching supports hierarchical and associated results...
In this paper, to tackle with uncertainty in the real world, the light-weight ontology drive approach is proposed for the realization of context dependent services. We concentrate on position information and an operation history, as a user's context, and develop our location-aware content delivery system. Through the proofing experiments in Orange Hall, Expo 2005 Aichi and Science Square Tsukuba,...
In this paper, we propose an integrated OWL data mining and query system architecture for expressing the mined knowledge in the OWL format and for effectively answering users' queries. The proposed system consists of five sub-systems: query parser, rule inference system, ontology management system, knowledge generation system, and knowledge management system. We expect the architecture can provide...
