Recent emerging technologies such as internetworking and the World Wide Web (WWW) have signiicantly expanded the types, availability, and volume of data accessible to an information management system. In this new environment it is imperative to view an information source at the level of its relevant semantic concepts. We propose that these semantic concepts(More)
Workkows are composite activities that can be used to support and automate multisystem applications involving humans, heterogeneous databases and legacy systems. The traditional atomic transaction model, successful for centralized and homogeneous applications, is not suitable for supporting such workkows. Intertask dependencies, which are conditions(More)

The web consists of huge amounts of data available in a variety of digital forms stored in thousands of repositories. Approaches that use the semantics of information captured in the metadata extracted from the data are being viewed as an appealing approach, especially in the context of the Semantic Web effort. We present in this chapter a discussion on(More)
—Video search has become a very important tool, with the ever-growing size of multimedia collections. This work introduces our Video Semantic Indexing system. Our experiments show that Residual Vectors provide an efficient way of aggregat-ing local descriptors, with complementary gain with respect to BoVW. Also, we show that systems using a limited number(More)
This paper examines the feasibility and efficiency of representation of wireless networks using graph abstractions. These abstractions represent wireless nodes and interactions between them as vertices and edges in a labelled graph. Vertices are defined with respect to different environmental and network protocol settings on a node while edges correspond to(More)
The World Wide Web is fast becoming a ubiquitous computing environment. Prevalent keyword-based search techniques are scalable, but are incapable of accessing information based on concepts. We investigate the use of concepts from multiple, real-world pre-existing, domain ontologies to describe the underlying data content and support information access at a(More)
