Internet of services provides the services capabilities to interact and collaborate. Users are able to create, share and access services by means of heterogeneous devices and interaction channels, in extremely personalized ways. However, in the dynamic and ever-growing scenario, lacks of customization and flexibility have become more and more crucial. In this paper, a QoS preference oriented se...

Cyber-physical systems (CPS) have received much attention from both academia and industry. An increasing number of functions in CPS are provided in the way of services, which gives rise to an urgent task, that is, how to recommend the suitable services in a huge number of available services in CPS. In traditional service recommendation, collaborative filtering (CF) has been studied in academia,...

  One of the most famous methods for recommendation is user-based Collaborative Filtering (CF). This system compares active user’s items rating with historical rating records of other users to find similar users and recommending items which seems interesting to these similar users and have not been rated by the active user. As a way of computing recommendations, the ultimate goal of the user-ba...

Service-oriented systems are usually built on top of Web service components, which are distributed across the Internet, making dependability a big challenge. In this paper, we propose a runtime dependability evaluation framework for fault tolerant Web services to attack this crucial problem. We first propose a user-collaborative framework for collecting Web service QoS information from both the...

purpose: to customize clinical practice guidelines (cpgs) for cataract management for iranian population. methods: first, four cpgs (american academy 2006 and 2011, royal college of ophthalmologists 2010 and canadian ophthalmological society evidence-based clinical practice guidelines 2008) were selected from a number of available cpgs for cataract management in the literature. second, all reco...

The Grid paradigm implies the sharing of a variety of resources across multiple administrative domains. In order to execute a work-flow using these distributed resources an instrument is needed to co-allocate resources by reaching agreements with the different local scheduling systems involved. Apart from compute resources to execute the work-flow the co-ordinated usage of other resource types ...
