AbstrAct: In biosciences, data mining is concerned with processing large amount of data which is characterized by hetero-geneity, ever changing and spread in different complex environments. Resource discovery from massive data poses a formidable task for many newer as well as routine applications. The issues addressed in the massive data environments so far are the hetero-geneity issues and the...

This paper presents a fully distributed resource discovery and reservation system. Verification of such a system is important to ensure the execution of distributed applications on a set of resources in appropriate conditions. A semi-formal model for his system is presented using probabilistic timed automata. This model is timed, parametric and probabilistic, making it a challenge to the parame...

Resource discovery is a problem common to almost all distributed systems. Instead of resulting in a one or a small number of discovery mechanisms, completely different and incompatible discovery services have proliferated. It can be reasonably argued that a discovery protocol optimised for small wireless LANs, such as Bluetooth piconets, is unlikely to be suitable for enterprise scale networks ...

Resource Discovery is an important key issue in grid systems since resource reservation and task scheduling are based on it. This paper proposes a novel semantic-based scalable decentralized grid RD framework. The paper integrates ontology, Peer-to-Peer network and intelligent agents to build the framework. The framework consists of an ontology model, an agent model, and a set of algorithms for...

Automatic metadata generation may provide a solution to the problem of inconsistent, unreliable metadata describing resources on the Web. The Resource Description Framework (RDF [10]) provides a domain-neutral foundation on which extensible element sets can be defined and expressed in a standard notation. This paper describes how an automatic classifier, that classifies HTML documents according...

With huge amounts of information connected to the global information network (Internet), e cient and e ective discovery of resources from the \global information base" has become an imminent research issue, especially with the advent of the Information Highway. This article proposes the use of novel Arti cial Intelligence and Database techniques (Assumption Grammars, Concept Hierarchies, Multi-...

An important aspect of Grid computing is publication resource service and discovery resource service. Grid computing is based on this kind of mechanism. A Grid service is an extended Web service that conforms to the Open Grid Service Infrastructure (OGSI) specification. The shortcoming of current Web service technology only provides syntactic description. In this paper, we analyze the limitatio...

We develop a new method to rank the degree of similarity between Boolean expressions, contrast it with other known methods, and describe its implementation. Our method reduces time and space complexity from exponential to polynomial in the number of Boolean terms.

When searching information in a retrieval system people use a variety of terms to describe their information needs When the terms used in a query are di erent from those indexed by the system users fail to obtain the information they want This is called the vocabulary problem This problem has been studied and discussed in information retrieval for decades Recently Deerwester et al proposed a ne...

As the WWW grows at an increasing rate, eeorts to make the technology more manageable are highly in demand. Applying advanced information retrieval techniques is one approach to such eeorts. Despite the potential beneet of these techniques in reducing users information overload and improving the eeectiveness access to on-line information, little research has been done on applying them to WWW en...
