This paper describes the design and implementation of S W O R D , a scalable resource discov ery serv ice for w ide-area distributed sy stems. S W O R D locates a set of machines matching user-specifi ed constraints on both static and dy namic node characteristics, including both single-node and inter-node characteristics. W e ex plore a range of sy stem architectures to determine the appropria...

Social computing initiatives that mark a shift from personal computing towards computations involving collective action, are driving a dramatic evolution in modern decision-making. Decisionmakers or stakeholders can now tap into the power of tremendous numbers and varieties of information sources (crowds), capable of providing information for decisions that could impact individual or collective...

We develop a technique we call spectral filtering, for discovering high-quality topical resources in hyperlinked corpora. Through relevance and quality judgements collected from 37 users, we show that, over 26 topics, spectral filtering usually finds web pages that are rated better than those returned by the hand-compiled Yahoo! resource list, and by the Altavista search engine.

Massive distributed cooperative computing in networks involves marshaling large collections of network nodes possessing the necessary computational resources. In order for the willing nodes to act in a concerted way they must first discover one another. This is the general setting of the Resource Discovery Problem (RDP). There are solutions for this problem that achieve impressive efficiency in...

A core goal of librarians is to maximize usage of the content to which their libraries subscribe. Webscale or resource discovery systems offer a single search box for library users to access subscribed content. This article examines usage data at the University of Huddersfield to show how resource discovery has helped to increase the usage of publisher content, which has been made available to ...

Several systems adopting Peer-to-Peer (P2P) solutions for resource discovery in Grids have recently been proposed. This report looks at a P2P resource discovery framework aiming to manage various Grid resources and complex queries. Following the discussion on characteristics of Grid resources and related query requirements, a DHT-based framework leveraging different P2P resource discovery techn...

Efficient Resource discovery mechanism is one of the fundamental requirement for Grid computing systems, as it aids in resource management and scheduling of applications. Resource discovery involves searching for resources that match the user’s application requirements. Various kinds of solutions to Grid resource discovery have been developed, including the centralised and hierarchical informat...

Intelligent discovery model with the concept expression for information security under the information security resource grid is proposed in this thesis, in which Concept Expression is adopted in the formal method of description on information security knowledge, this method is used to support reasoning and semantically intelligent discovery. Characterization and resource optimization are two m...

Considerable efforts are going on towards the decentralization of Grid Information Service (GIS). In order to facilitate resource sharing it is important that Grid Resource Management System (GRMS) finds the location of desired service and timely fashion. Current approaches to resource discovery in GIS are based on centralized or hierarchical client/server models. In this model one or more inde...
