An SOA Approach To Sensor Services
The purpose of this project is to demonstrate the use of Semantic Web design and Service Oriented Architecture principles to make sensor information and data readily accessible to clients across the Internet. This project produced a set of XML files that described sensors, defined an ontology that described the vocabulary used in the XML files, and configured an existing registry technology for use within our sensor domain
Enterprise knowledge management: introducing new technologies in traditional Information Systems
Knowledge management systems described in research papers are rarely seen implemented in business realities, at least on a large scale. Companies are often tied to existing systems and cannot or would not revolutionize the situation to accommodate completely new solutions. Given this assumption, this work investigates several small-scale modifications that could be applied to in-place Information Systems so as to improve them with new technologies without major transformations and service discontinuities. The focus is interoperability, with a particular stress on the promotion of the ebXML registry standard. A universal interface for document management was defined, and the conforming “interoperable” DMSs were arranged within an architecture explicitly designed for ebXML-compliant access. This allowed standards-based manipulation of legacy DM systems. The closely related topic of Semantic knowledge management was also tackled. We developed Semantic tools integration for traditional repositories with low architectural impact. Finally, we discussed a novel issue in document categorization, and a new kind of ontology that could be used in that contex
A Review on Framework and Quality of Service Based Web Services Discovery
Selection of Web services (WSs) is one of the most important steps in the application of different types of WSs such as WS composition systems and the Universal
Description, Discovery, and Integration (UDDI) registries. The more available these WSs
on the Internet are, the wider the number of these services whose functions match the various service requests is. Selecting WSs with higher quality largely depends on the quality of service (QoS) since it plays a significant role in selecting such services. In
achieving this selection of the best WSs, the potential WSs are ranked according to the user’s necessities on service quality. In many cases, the value of QoS ontology is realized by its support for nonfunctional features of WSs. This ontology is also capable of providing
solutions to the interoperability of QoS description. Moreover, based on the QoS ontology,
it becomes more possible to develop a framework of semantic WS discovery. The framework enhances the automatic discovery of WSs and can improve the users’ efficiency in finding the best web services. Thus, Web Services are software functionalities publish
and accessible through the Internet. Different protocols and web mechanism have been defined to access these Services
Service-Oriented Middleware for the Future Internet: State of the Art and Research Directions
International audienceService-oriented computing is now acknowledged as a central paradigm for Internet computing, supported by tremendous research and technology development over the last ten years. However, the evolution of the Internet, and in particular, the latest Future Internet vision, challenges the paradigm. Indeed, service-oriented computing has to face the ultra large scale and heterogeneity of the Future Internet, which are orders of magnitude higher than those of today's service-oriented systems. This article aims at contributing to this objective by identifying the key research directions to be followed in light of the latest state of the art. This article more specifically focuses on research challenges for service-oriented middleware design, therefore investigating service description, discovery, access and composition in the Future Internet of services
Internet of Things Strategic Research Roadmap
Internet of Things (IoT) is an integrated part of Future Internet including existing and evolving Internet and network developments and could be conceptually defined as a dynamic global network infrastructure with self configuring capabilities based on standard and interoperable communication protocols where physical and virtual “things” have identities, physical attributes, and virtual personalities, use intelligent interfaces, and are seamlessly integrated into the information network
