Tool Support for Distributed Workflow Management with Task Clustering

Distributed Global Transaction Support for Workflow Management Applications

Workflow management systems require advanced transaction support to cope with their inherently long-running processes. The recent trend to distribute workflow executions requires an even more advanced transaction support system that is able to handle distribution. This report presents a model as well as an architecture to provide distributed advanced transaction support. Characteristic of the t...

Distributed Task Management by Means of Workflow Atoms

In this paper we describe Wf-ATOMS, a framework for the specification and management of workflows, whose engine is integrated in a multi user and distributed task management system. The process models include features standard in other workflow management systems, concerning the form in which the activities forming the processes interact, and other features usually managed by user-task manageme...

Entropy-based Consensus for Distributed Data Clustering

The increasingly larger scale of available data and the more restrictive concerns on their privacy are some of the challenging aspects of data mining today. In this paper, Entropy-based Consensus on Cluster Centers (EC3) is introduced for clustering in distributed systems with a consideration for confidentiality of data; i.e. it is the negotiations among local cluster centers that are used in t...

Distributed, Interoperable Workflow Support for Electronic Commerce

This paper describes a flexible distributed transactional workflow environment based on an extensible object-oriented framework built around class libraries, application programming interfaces, and shared services. The purpose of this environment is to support a range of EC-like business activities including the support of financial transactions and electronic contracts. This environment has as...
