Semantic Interoperability of Heterogeneous Semantic Resources

This paper presents a three-step approach to enhance interoperability between heterogeneous se- mantic resources. Firstly, we construct homogeneous representations of these resources in a pivot format, namely OWL DL, with respect to the semantics expressed by the original representation languages. Secondly, mappings are established between concepts of these standardised resources and stored in a so-called articulation ontology. Thirdly, an approach for ranking those mappings is suggested in order to best fit users' needs. This approach is currently being implemented in the Semantic Resources “Interoperabilisation” and Linking System (SRILS). The mapping results as well as the work to be done are discussed.

Evaluating Thesaurus Alignments for Semantic Interoperability in the Library Domain

Thesaurus alignments play an important role in realizing efficient access to heterogeneous cultural-heritage data. Current technology, however, provides only limited value for such access because it fails to bridge the gap between theoretical study and practical application requirements. This article explores common real-world library problems and identifies solutions that focus on the application-embedded study, development, and evaluation of matching technology.

一种支持语义互操作的Web服务注册管理机制

随着互联网中Web服务的急剧增长,大量服务资源已呈分布异构状态,仅仅靠单纯的语义信息已经不能满足Web服务的动态集成和随需而变.尽管网络通信协议、基于XML的各种信息交换协议基本解决了网络信息资源之间互连和互通的问题,但自治异构的Web服务之间的互操作问题还有待解决.针对以上问题,基于国际标准ISO/IEC 19763-3:MFBOR,构建了一种语义互操作性Web服务注册管理框架,并提出了Web服务的2种语义互操作能力,初步实现了Web服务资源由“孤岛性”向“互操作性”的转变.

Interoperability results for Semantic Web technologies using OWL as the interchange language

Using Semantic Web technologies in complex scenarios requires that such technologies correctly interoperate by interchanging ontologies using the RDF(S) and OWL languages. This interoperability is not straightforward because of the high heterogeneity in Semantic Web technologies and, while the number of such technologies grows, affordable mechanisms for evaluating Semantic Web technology interoperability are needed to comprehend the current and future interoperability of Semantic Web technologies.This paper presents the OWL Interoperability Benchmarking, an international benchmarking activity that involved the evaluation of the interoperability of different Semantic Web technologies using OWL as the interchange language. It describes the evaluation resources used in this benchmarking activity, the OWL Lite Import Benchmark Suite and the IBSE tool, and presents how to use them for evaluating the OWL interoperability of Semantic Web technologies. Moreover, the paper offers an overview of the OWL interoperability results of the eight tools participating in the benchmarking: one ontology-based annotation tool (GATE), three ontology frameworks (Jena, KAON2, and SWI-Prolog), and four ontology development tools (Protégé Frames, Protégé OWL, SemTalk, and WebODE).

A case of using the Semantic Interoperability Framework for custom orthopedic implants manufacturing

The efficiency and effectiveness of the daily practice in orthopedic surgery depend on the availability, interoperability and unique access to a wide set of information, related to the patient’s medical record and diagnosis, domain knowledge and available resources and staff. The most important of the tangible resources, needed for the therapeutic or preventive actions are orthopedic implants. In some cases, the implants may be highly complex and customized products, which need to be manufactured (assembled) on basis of the above information in a shortest possible timeframe. In this paper, the case of the custom orthopedic implants manufacturing is described from the perspective of the collaborative enterprising, with special consideration of the interoperability issues of the involved enterprise collaboration. It is shown how the previously developed Semantic Interoperability Framework can be used to improve the efficiency of the manufacturing and other relevant processes.     

支持角色与目标模型的语义互操作性管理机制

当前业界存在多种需求模型,模型本身结构各异,其间的语义互操作也存在巨大的困难.由于缺乏支持需求模型互操作管理以及互操作能力评估的高效且通用的方法,导致了此类困难的延续.为了实现需求模型间高效地协作与交互,本文提出了一种机制,以支持需求模型间有效的互操作注册,合理的互操作管理以及量化的互操作评估.从现有的角色与目标模型中抽取出公共的模型元素;建立一种元模型方法以支持角色与目标模型的互操作管理;研究如何通过互操作管理机制对角色与目标模型进行注册与检索;最后阐述了一种度量方法以支持模型间的互操作能力评估,进而准确引导异构角色与目标模型间的协作.

Semantic Ontology Mapping for Interoperability of Learning Resource Systems using a rule-based reasoning approach

There is an increasing demand for sharing learning resources between existing learning resource systems to support reusability, exchangeability, and adaptability. The learning resources need to be annotated with ontologies into learning objects that use different metadata standards. These ontologies have introduced the problems of semantic and structural heterogeneity. This research proposes a Semantic Ontology Mapping for Interoperability of Learning Resource Systems. To enable semantic ontology mapping, this research proposes conflict detection and resolution techniques for both semantic and structural conflicts. The Semantic Bridge Ontology has been proposed as a core component for generating mapping rules to reconcile terms defined in local ontologies into terms defined in the target common ontology. This work defines the reasoning rules to classify related learning objects to enhance the powerful deductive reasoning capabilities of the system. As a consequence, ontology-based learning object metadata are generated and used by the semantic query engine to facilitate user queries of learning objects across heterogeneous learning resource systems.     

The Application of Workflow Technology in Semantic B2B Integration

Workflow Management Systems (WFMSs) are often used in context of B2B integration as a base technology to implement business-to-business (B2B) integration processes across enterprises. In this context the notion of distributed inter-organizational workflows is introduced to indicate the collaboration of enterprises on a process level. This notion requires a thorough examination presented in this article since WFMSs were not designed with inter-enterprise distribution as one of the design goals. At a closer look, the proposed use of WFMSs in context of B2B integration is often very naïve and inappropriate. Consequently it does not address the real requirements found in enterprises. Enterprises do not share common workflow definitions, let alone common workflow instance execution state and have no intent to do so due to competitive knowledge protection. Furthermore, trading partner specific business rules within enterprises are not accounted for leading to an unwanted explosion of workflow definitions. This article clarifies the notion of distributed inter-organizational workflows as well as private and public processes. Based on this definition, the appropriate use of WFMSs is shown in context of an overall B2B integration solution that allows enterprises to protect their competitive knowledge while participating in B2B integration.     

Interoperability of Learning Objects Copyright in the LUISA Semantic Learning Management System

Abstract

Semantic Web technology is able to provide the required computational semantics for interoperability of learning resources across different Learning Management Systems (LMS) and Learning Object Repositories (LOR). The EU research project LUISA (Learning Content Management System Using Innovative Semantic Web Services Architecture) addresses the development of a reference semantic architecture for the major challenges in the search, interchange, and delivery of learning objects in a service-oriented context. One of the key issues, highlighted in this paper, is Digital Rights Management (DRM) interoperability. A Semantic Web approach to copyright management has been followed, which places a Copyright Ontology as the key component for interoperability among existing DRM systems and other licensing schemes like Creative Commons. Moreover, Semantic Web tools like reasoners, rule engines and semantic queries facilitate the implementation of an interoperable copyright management component in the LUISA architecture.
