In a service oriented world, performance plays a vital role in the success of any IT system. For an application running in a production environment, whenever there is a change in the workload or workload pattern, utilization of major server resources like cpus, disks, memory, network etc. will also change. In this paper, we are extending our methodology to estimate the server resource utilization...

This article focuses on proposed semantically enhanced model of decision support system for learning management system (LMS). The model is based on a survey of LMSs and various plugins used in these to improve educational process. Systems based on semantic technologies are capable of integrating heterogeneous data, flexibly changing data schemas, semantic search (using ontologies), and joint knowledge...
Semantic metadata has many uses in online virtual environments, but the technology for acquiring and managing metadata is not yet fully developed. This paper presents a partial solution that combines and extends traditional top-down and bottom-up approaches to semantic annotation. The paper proposes a metadata architecture composed of three layers, each of which has a metadata store and an interface...
T.R.A.F.F.I.C is an acronym representing Transit Response Analysis for Facilitating Informed Commuters. T.R.A.F.F.I.C. is a web service hosted in the cloud which uses real-time Big Data from TRANSCOM, a non-profit firm. We are mining for potential congested traffic patterns which may impair one's timely commute during rush hour. T.R.A.F.F.I.C is based on the service-oriented architecture (SOA) web...
