TL;DR: It is concluded that delegating part of the scheduling responsibilities to the underlying scheduling layers promotes separation of concerns and is a good way to balance the performance among the different grid systems.

TL;DR: An approach to the discovery of the phishing target of a suspicious webpage is proposed, which is based on construction and reasoning of the Semantic Link Network (SLN) of the suspicious webpage.

TL;DR: This paper describes a framework for implementing distributed ontology-based knowledge management systems (DOKMS), and presents an implementation of the designed framework in the K-link+ system and shows the suitability of this approach through a use case.

TL;DR: This work proposes an approach called CRET: Context Reasoning using extended Evidence Theory, which applies the evidence theory to context reasoning in pervasive computing environments and shows that CRET is desirable for pervasive applications.

TL;DR: A P2P-based hybrid collaborative filtering mechanism for the support of combining user-based and item attribute-based ratings is considered and a Hybrid collaborative filtering (HCF) algorithm is presented to improve the predictive accuracy.

TL;DR: The experimental results show the number of visited nodes and performed operations, as a result of query forwarding, are smaller than in comparable approaches and the cost of update in the proposed algorithm is also lower, therefore, the algorithm can effectively improve the system efficiency for resource discovery.

TL;DR: This paper describes how the problem of job management has been addressed in the gLite middleware by means of the CREAM and CEMonitor services.
