In this paper we present a framework in which heterogeneous agents can argue over the viability of a human organ for transplantation. This collaborative decision making process among human and/or software agents is me...

Provenance is a concept often used in the Art world to refer to the documented history of an artifact, providing information about the artifact's lineage and authenticity. Provenance-aware applications similarly allow their users to have confidence about the data they produce, and can enable users to make judgements relating to notions of trust, accountability, validation, replication and compliance of their data. PrIMe is a software engineering methodology for adapting applications to enable them to interact with a provenance middleware layer, thereby making them provenance-aware. Such applications allow users to answer questions about provenance use cases, which are descriptions of scenarios in which a user interacts with a system by performing particular functions on that system. In order to illustrate how PrIMe can make applications provenance-aware, an Organ Transplant Management example application is used. Copyright 2006 ACM.

Daily operation and maintenance tasks are needed to guarantee the correct performance of constructed wetlands. The definition of these activities is a complex task since these actions vary according to the characteristics of each facility. To support the definition of these operation and maintenance protocols an Environmental Decision Support System (EDSS) has been constructed (EDSS-maintenance). The methodology used to develop EDSS-maintenance is based on the following five steps: environmental problem analysis, data and knowledge acquisition, model selection, model implementation and evaluation process. The first four steps have been finished;however, the evaluation process is ongoing. This document presents a new approach for this step: two numerical indices allow (a) verifying the performance of the EDSS-maintenance and (b) validating the compliance of the protocols with the user requirements. Moreover, another index enables an easy revision and improvement of the knowledge bases (problems, causes and actions) and so enhances the decision support system.

The complexity of environmental problems makes the management of environmental systems especially difficult to be undertaken by traditional software systems. Particularly river catchment systems are very intricate to manage in order to achieve a good quality and quantity of water at the river. Multi-Agent systems (MAS) are able to cope with this complexity by integrating all the water systems involved at catchment scale through several agents who model real environmental situations. In this paper we describe the design of a MAS for simulating multiple scenarios in a river catchment system in order to support the decision-making of river basins management. The River Basin MAS has been designed and their functionalities have been studied. Moreover, we have selected the agent platform Jadex as a starting software platform for our new software development. With this proposal, we intend to provide feasible solutions at catchment scale throughout modelling and simulation of different scenarios in a river basin system.

Over recent years a huge library of data mining algorithms has been developed to tackle a variety of problems in fields such as medical imaging and network traffic analysis. Many of these techniques are far more flexible than more classical modelling approaches and could be usefully applied to data-rich environmental problems. Certain techniques such as Artificial Neural Networks, Clustering, Case-Based Reasoning and more recently Bayesian Decision Networks have found application in environmental modelling while other methods, for example classification and association rule extraction, have not yet been taken up on any wide scale. We propose that these and other data mining techniques could be usefully applied to difficult problems in the field. This paper introduces several data mining concepts and briefly discusses their application to environmental modelling, where data may be sparse, incomplete, or heterogenous.
