Due to the openness and dynamic characteristics of the network environment, the failure of component services in a composite Web service (CWS) can occur. CWS is a conglomeration of existing Web services (WSs) interacting together to offer a new value-added service. Hence, it is necessary to perform some transactions to ensure its correct and reliable execution. However, their introduction complicates...
The notion of object-based storage devices (OSDs) has been proposed to overcome the limitations of the traditional block-level interface which hinders the development of intelligent storage devices. The main idea of OSD is to virtualize the physical storage into a pool of objects and offload the burden of space management into the storage device. We explore the possibility of adopting this idea for...
This paper proposes a hybrid approach in using Google Distance and WordNet together in a new method for the semantic similarity matching stage of web services discovery. We provide comparisons, using services recall and precision metrics, between our hybrid approach and our earlier lightweight Google Distance-based approach for web services discovery. Our performance evaluation demonstrates the trade-offs...
Problems with ontology-dependent approaches for dynamic web services composition occur when ontologies are poorly maintained or unavailable in a domain, or the costs of maintenance exceed their benefits. To resolve such problems, this paper proposes the use of Google Distance as an ontology-independent method for the semantic similarity matching stage of web services discovery. Further, it provides...
iConnect is an abstraction that encapsulates all of a virtual machine's interactions with outside entities. Its intent is to exploit semantic information to better support the end-to-end requirements of such VM communications. Focusing on the I/O performed by VMs and leveraging the fact that modern systems already have to virtualize the physical devices used by VMs, this paper shows that the iConnect...
