Semantic Web Policies – A Discussion of Requirements and Research Issues

Disassembly, as one of the core steps in the End of Life (EOL) activities, has been a popular topic of research in both industrial and academic areas. It not only reduces product lifecycle cost, but also substantially influences environmental impact. Although different methods have been proposed for tackling different aspects of the disassembly planning problems, certain gaps still exist. For example, in the case of the disassembly sequencing, traditional methods focus mainly on the geometry and topology constraints, but omit the important technical constraints like force (gravity), connector type, etc.; it makes these methods less efficient and realistic. Also, the determination of an optimal disassembly sequence requires an extensive exchange and sharing of the disassembly related knowledge among the different stakeholders like manufacturers, product designers, maintenance staffs and material engineers. A mechanism to support such information interoperability is important in the disassembly process. In order to address those research issues, this paper proposes a Semantic Web based Disassembly Planning Framework. In the framework, the proposed “Disassembly Core Ontology” (DCO) serves as a formal, explicit information core for different users like product designer and disassembler. By exploiting the rich semantic knowledge (like gravity, connector type, etc.) that has been explicitly embedded in the proposed DCO, it has been demonstrated that the semantic web approach has potentials to address both efficiency- and interoperability-related issues in disassembly planning problems.

Geoprocessing Workflow

In a service-oriented environment, large volumes of geospatial data and diverse geoprocessing functions are accessible as services. An intelligent mechanism is required to facilitate discovery and integration of geospatial data and services so as to enable semi-automated or automated geospatial knowledge discovery. This chapter addresses key research issues for Semantic Web enabled intelligent geoprocessing service chaining. A set of applicable solutions are described, including a common data and service environment, semantic descriptions of geoprocessing services, and a general process for intelligent generation of geoprocessing workflow. Some use cases illustrate the applicability of such solutions. A proof-of-concept prototype system is implemented and some use cases help to demonstrate the applicability of the current approach.

The Web

This highly topical text considers the construction of the next generation of the Web, called the Semantic Web. This will enable computers to automatically consume Web-based information, overcoming the human-centric focus of the Web as it stands at present, and expediting the construction of a whole new class of knowledge-based applications that will intelligently utilize Web content. The text is structured into three main sections on knowledge representation techniques, reasoning with multi-agent systems, and knowledge services. For each of these topics, the text provides an overview of the state-of-the-art techniques and the popular standards that have been defined. Numerous small programming examples are given, which demonstrate how the benefits of the Semantic Web technologies can be realized at the present time. The main theoretical results underlying each of the technologies are presented, and the main problems and research issues which remain are summarized. Based on a course on 'Multi-Agent Systems and the Semantic Web' taught at the University of Edinburgh, this text is ideal for final-year undergraduate and graduate students in Mathematics, Computer Science, Artificial Intelligence, and Logic and researchers interested in Multi-Agent Systems and the Semantic Web.

AbstractThis paper presents contributions of the ANR McBIM (Communicating Material for BIM) project regarding Digital Building Twins, specifically how Semantic Web technologies allow providing explainable decision-support. Following an introduction stating our understanding of a Digital Building Twin (DBT), namely a lively representation of a buildings' status and environment, we identify five main research domains following the study of main research issues related to DBT. We then present the state-of-the-art and existing standards for digitizing the construction process, Semantic Web technologies, and wireless sensor networks. We further position the main contributions made so far in the ANR McBIM project's context according to this analysis, e.g., sensor placement in the communicating material and explainable decision-support.

Wide Range

Scanning tunneling microscopy (STM) has evolved rapidly in the past few years. Major developments have occurred in instrumentation, theory, and in a wide range of applications. In this paper, an overview of the application of STM and related techniques to polymers will be given, followed by a discussion of current research issues and prospects for future developments. The application of STM to polymers can be conveniently divided into the following subject areas: atomic scale imaging of uncoated polymer structures; topographic imaging and metrology of man-made polymer structures; and modification of polymer structures. Since many polymers are poor electrical conductors and hence unsuitable for use as a tunneling electrode, the related atomic force microscopy (AFM) technique which is capable of imaging both conductors and insulators has also been applied to polymers.The STM is well known for its high resolution capabilities in the x, y and z axes (Å in x andy and sub-Å in z). In addition to high resolution capabilities, the STM technique provides true three dimensional information in the constant current mode. In this mode, the STM tip is held at a fixed tunneling current (and a fixed bias voltage) and hence a fixed height above the sample surface while scanning across the sample surface.
