Policy-based autonomic control service

Recently, there has been a considerable interest in policy-based, goal-oriented service management and autonomic computing. Much work is still required to investigate designs and policy models and associate meta-reasoning systems for policy-based autonomic systems. In this paper we outline a proposed autonomic middleware control service used to orchestrate selfhealing of distributed applications. Policies are used to adjust the systems autonomy and define self-healing strategies to stabilize/correct a given system in the event of failures

A Pattern Based Approach for Re-engineering Non-Ontological Resources into Ontologies

With the goal of speeding up the ontology development process, ontology engineers are starting to reuse as much as possible available ontologies and non-ontological resources such as classification schemes, thesauri, lexicons and folksonomies, that already have some degree of consensus. The reuse of such non-ontological resources necessarily involves their re-engineering into ontologies. Non-ontological resources are highly heterogeneous in their data model and contents: they encode different types of knowledge, and they can be modeled and implemented in different ways. In this paper we present (1) a typology for non-ontological resources, (2) a pattern based approach for re-engineering non-ontological resources into ontologies, and (3) a use case of the proposed approach

Twenty years of electronic markets research: looking backwards towards the future

Over the past 20 years the field of electronic markets has seen a considerable proliferation and differentiation. This position paper takes the opportunity of the 21st volume of “Electronic Markets” to look back at important developments and insights, suggesting a framework that captures the multiple facets and indeed empirical breadth and depths of this concept. It comprises three perspectives which include the market environment, governance choices by economic actors as well as the entrepreneurial dynamics of firms who initiate and operate market platforms as their business. In addition, we propose to study the interplay of technological, market, and institutional drivers in order to understand the phenomenon of electronic markets, which is also a precondition for designing electronic markets. Both activities involve more than an economically motivated choice between the discrete alternatives of markets and hierarchies. Rather, electronic markets are configurations across multiple, interdependent dimensions: Technology is an important force in shaping the field, but needs to be complemented by considerations of the competitive environment and the setting of rules in order to ensure efficient and effective plays of the game. Based on this framework, this position paper develops six propositions for the future of electronic markets. Overall, the advantages of intermediated structures, an ongoing technological sophistication, as well as further innovation in market mechanisms and services make electronic markets an ena-bler for many interorganizational value chains. While we are confident that the ingenuity of inventors will yield a flow of innovations, recent economic crises have shed a dark shadow over the sustainability of electronic markets. They call for suitable rules and regulation amenable to economic prosperity and stability to be agreed upon on a broad level

Internet for libraries

This paper discusses about internet and its usage in Libraries. It discusses about Internet 2, which began in the last quarter of 1996, is a collaborative effort of 34 US academic and research institutions (which has swelled to 135 now) working with industry and government. on. The avenues for exploitation of Internet resources by libraries are unlimited and endless. It provides access to a variety of commercial and non-commercial information sources including bibliographic and full-text databases, table of contents of primary journals, electronic and online journals, books and newsletters, library catalogues and OPACs, graphics databases, multimedia walk through programs, and audio visual clip art databases, email, directories, product catalogues, campus information systems, etc. Internet is also a test bed for electronic document delivery, electronic publishing, publicity and marketing of products and services, training and education, and integrated access to local and external informatio

Cirrus, A Digtially Responsible Global FIlesystem

Cirrus is a distributed filesystem that uses an overlay network that extends the service domain of file servers to global scale without diminishing the quality of service. Cirrus, developed over many years, is operational today and is ready for testing and bench marking. Cirrus’ distributed shared memory implementation provides a fast and secure method of transporting all network traffic within the overlay network
