The growing number of web services advocates distributed discovery infrastructures which
are semantics-enabled and support quality of service (QoS). In this paper, we introduce a …

In open networked systems, each node shares part of its informational resources on the
network and is responsible of providing an ontological description for them. To enable …

This paper studies the resource discovery problem in a Grid system, in which global trust
values play a crucial role. The proposed mechanism suggests that routers and resources …

E-learning plays a significant role in educating large number of students. In the delivery of e-

In this paper, we describe an ontology-based collaboration model for supporting semantic
interoperability in open networked systems. We characterize discovery and matchmaking …

Resource discovery is a key issue for Grid systems in which applications are composed of
hardware and software resources that need to be located. Classical approaches to Grid …

This paper studies the Resource Discovery problem in a dynamical grid based on a grid-
router model. This model suggests that the grid can be seen as an environment comprised …
