Technologies for the efficient and effective reuse of ontological knowledge are one of the key success factors for the Semantic Web. Putting aside matters of cost or quality, being reusable is an intrinsic property of ontologies, originally conceived of as a means to enable and enhance the interoperability between computing applications. This article gives an account, based on empirical evidence and real-world findings, of the methodologies, methods and tools currently used to perform ontology-reuse processes. We study the most prominent case studies on ontology reuse, published in the knowledge-/ontology-engineering literature from the early nineties. This overview is complemented by two self-conducted case studies in the areas of eHealth and eRecruitment in which we developed Semantic Web ontologies for different scopes and purposes by resorting to existing ontological knowledge on the Web. Based on the analysis of the case studies, we are able to identify a series of research and development challenges which should be addressed to ensure reuse becomes a feasible alternative to other ontology-engineering strategies such as development from scratch. In particular, we emphasize the need for a context- and task-sensitive treatment of ontologies, both from an engineering and a usage perspective, and identify the typical phases of reuse processes which could profit considerably from such an approach. Further on, we argue for the need for ontology-reuse methodologies which optimally exploit human and computational intelligence to effectively operationalize reuse processes. 相似文献

智能服务--Web服务和语义Web集成研究 总被引:11,自引:0,他引:11
现有Web主要是为人使用Web上的内容设计,如何自动发现、执行、组合及互操作Web上的信息,提供智能服务,是Web服务努力的方向,Web服务虽然也制定了发现、描述、信息交换的标准,但这些标准不支持智能服务,其原因是现有Web服务缺乏清楚的语义标记,该文提出将语义Web技术和Web服务结合来实现智能服务的思想,即为Web服务增加语义标记以实现Web服务的智能性,并就其可行性进行了阐述,最后给出了具体实现的方法。 相似文献

The Service-Oriented-Architecture (SOA) development paradigm has emerged to make an improvement in critical situations such as creating, modifying and extending solutions in the domain of business processes integration. Web services technologies are considered as the main units for SOA, for both intra- and inter-enterprise communication. Nevertheless, SOA does not have information about the events that occurs in business processes, which represents the main characteristics of supply chain management. Taking this into account, this paper proposes a middleware-oriented integrated architecture with the use of semantic features (concretely with the use of Linked Data) as data provider to offer a brokerage service for the procurement of products in a Supply Chain Management (SCM). As main contributions, our system provides a hybrid architecture that combines features of both SOA and EDA between several others. 相似文献

As the information on the Internet dramatically increases, more and more limitations in information searching are revealed, because web pages are designed for human use by mixing content with presentation. In order to overcome these limitations, the Semantic Web, based on ontology, was introduced by W3C to bring about significant advancement in web searching. To accomplish this, the Semantic Web must provide search methods based on the different relationships between resources.In this paper, we propose a semantic association search methodology that consists of the evaluation of resources and relationships between resources, as well as the identification of relevant information based on ontology, a semantic network of resources and properties. The proposed semantic search method is based on an extended spreading activation technique. In order to evaluate the importance of a query result, we propose weighting methods for measuring properties and resources based on their specificity and generality. From this work, users can search semantically associated resources for their query, confident that the information is valuable and important. The experimental results show that our method is valid and efficient for searching and ranking semantic search results. 相似文献

CRL:对语义Web上的Ontology表示语言DAML+OIL的一种扩充方案 总被引:3,自引:0,他引:3
Ontologies在语义Web中起着举足轻重的作用,它不仅能为人类用户而且能为软件Agent提供从语法层次到语义层次上的互操作性。DAML+OIL是专门为语义Web设计的一种Ontology描述语言,它将框架系统、描述逻辑和Web标准这三个不同领域的优点结合了起来,采用面向对象的方法用类和属性来描述领域的结构。但是DAML+OIL也有不足之处,其一是约束表达能力较弱,只能表示属性值的基数约束,不能表示属性值的区间约束;其二是不能表示任何规则,而无论是约束表示还是规则表示对Ontology都是非常重要的。该文提出一种对DAML+OIL的扩充方案,使得扩充后的DAML+OIL可以表示简单的规则和属性值的区间约束。 相似文献

近年来,Web服务技术的应用发展得越来越快。Web服务是基于横跨Internet的分布式计算。它依赖于服务提供者描述他们的服务性能和服务请求者用一种明白的、理论上可解释的格式来描述。Web服务使用标准的如XML、SOAP和HTTP之类的网页协议。它最后向Web交互领域延伸。 相似文献
