Workflow management systems usually interpret a workflow definition rigidly. However, there are real life situations where users should be allowed to deviate from the prescribed static workflow definition for various reasons, including lack of information and unavailability of the required resources. To flexibilize workflow execution, this paper proposes mechanisms that allow execution to proceed in the presence of incomplete information, by adopting presuppositions, and in the presence of negative information, by suggesting execution alternatives. This paper also presents an architecture for the workflow system, which is driven by ontologies that capture semantic relationships between workflows, resources and users.

Model-based design methods, and model-based architectures, have gained adoption in authoring applications for the WWW. This is further reinforced by the increasing visibility of the semantic Web, where models are intrinsic, described as metadata associated with the data made available to users and applications. Several proposals attempt to leverage this additional information to improve search functionalities, by incorporating semantic similarity (or proximity) measures into the search mechanism. In this paper we show how the availability of a semantic similarity evaluation engine can be used to enhance several functionalities of Web-based applications. In particular we show how such an infrastructure can be used to detect and suggest new relation instances, as well as propose an inferred ordering for the presentation of related information that reflects the semantic closeness of the corresponding information. The proposed engine is based on a hybrid spread activation algorithm applied to the concept instances graph.

This work presents a demonstration application where multimedia messaging service (MMS) was used to create a pervasive museum guide system. We present the framework to create a context-aware mobile application and show the importance of using multimedia content and commercially available infrastructures.

Distributed software development characterizes software production when team members are dispersed over time and distance. Several environments and tools are being developed to support this trend. Better communication and awareness support are some of the requirements. We argue that the available tools can be enhanced instead of replaced. This work presents a middleware for collaborative applications that increase group and workspace awareness information available to developers. This middleware-based approach helps groupware developers to construct enhanced tools, adapted to specific needs, reusing existing applications. This work describes the middleware architecture and presents examples of tool enhancement.

Nowadays there exist several cultural spaces in the Internet and some of the real museums have been using it as an extension of their walls. A virtual cultural space can present to visitors any kind of artistic manifestation represented in a digital format. We propose a multiagent architecture used to enhance communication in cultural environments. Our proposal is based on a 3D environment where users are represented by avatars. Each avatar has a personal agent that captures all the relevant user actions. We have also others types of agent which are responsible for providing communication services. Also, we present a study case showing how these concepts were implanted in the ICSpace (Internet cultural space) environment.
