Current state-of-the-art workflow systems are mainly concerned with the routing and assignment of tasks, providing little support for tasks related to administration and management. This deficiency is exacerbated in dynamic open environments, where services provided and managed by multiple autonomous authorities need to be integrated. Such environments significantly stretch the assumptions underlying current state-of-the-art workflow system designs, especially as network-centric applications become widespread. We propose a framework, service level management, for addressing all system administration in an integrated manner in the context of a workflow execution model that allows for dynamic adaptation (reconfiguration) of work sessions in a dynamic and heterogeneous run-time environment. Service level management requires a comprehensive monitoring infrastructure. We present our design for such an infrastructure, which is part of our current work towards developing the Aurora architecture for supporting work sessions.","PeriodicalId":194923,"journal":{"name":"Proceedings Ninth International Workshop on Database and Expert Systems Applications (Cat.

It is clear that the idea of managing separately the coordination aspect from the computation in a language has a lot of advantages in the development of those systems. Nevertheless, most of the coordination languages do not take care that additionally to managing coordination requirements, they must manage other kinds of \"openness\" related requirements in Open Systems. The most important requirement being to support the evolution of the coordination requirements themselves. This problem manifests during the software development process by the development over and over again of solutions to similar coordination problems. To tackle this problem, and instead of proposing a new language, we are attempting to develop an open set of adaptable and reusable software components that realize various useful coordination abstractions. With these components we provide explicit separation of coordination from computation, and facilitate reuse and evolution of coordination aspects in Open Systems.","PeriodicalId":194923,"journal":{"name":"Proceedings Ninth International Workshop on Database and Expert Systems Applications (Cat.

We have proposed a new representation for image contents using visual ontologies and wavelets. We will discuss how to represent the shape of objects/regions of interest, colour distribution and texture of the images integrating visual ontologies with wavelets. Our ideas are: (1) propose a set of meta ontologies and semantic descriptors (graphic and symbolic) for visual ontologies; (2) using visual ontologies and most significant coefficients of a 2D multiresolution wavelet transform to represent image contents. The visual ontologies are represented by a set of descriptors, relations, logic operators, and functions; (3) using a multiresolution wavelet transform to extract the colour and texture features of target images and map it into relevant visual ontologies. The query images can also be represented as visual ontologies or most significant coefficients of a 2-D multiresolution wavelet; (4) a spatial query can be integrated with other visual ontologies. The initial experiments have shown encouraging results.","PeriodicalId":194923,"journal":{"name":"Proceedings Ninth International Workshop on Database and Expert Systems Applications (Cat.
