This paper is presenting a generic ontology-based user modeling architecture, (OntobUM), applied in the context of a Knowledge Management System (KMS). Due to their powerful knowledge representation formalism and associated inference mechanisms, ontology-based systems are emerging as a natural choice for the next generation of KMSs operating in(More)
This paper describes an artificial agent system, designed to help people to adopt new knowledge sharing behaviours. This agent continuously observes the actions of the user in order to build and maintain a "behavioural profile" reflecting the level of adoption of the "desired" behaviours. Using this profile, and relying on a model borrowed from change(More)
In this paper, we present an agent-based system designed to support the adoption of knowledge sharing practices within communities. The system is based on a conceptual framework that, by modelling the adoption of knowledge management practices as a change process, identifies the pedagogical strategies best suited to support users through the various stages(More)
Successful implementation of IT-enabled change requires good management of the change process and of the various sources of resistance that typically accompany the introduction of such change. As a result, helping managers better understand the dynamics of organizational processes is an important objective for IS and IT educators. The EIS Simulation is a(More)
The aim of this paper is to assess the state-of-the-art in the Decision Support Systems field from both a research and a practice perspective. Three main dimensions of DSS research and practice are addressed: 1) supporting human decision-making processes, 2) integrating DSS into the organizational context, and 3) identifying new application domains. The(More)
The key to the approach illustrated in this paper is the use of Information Technology to model the dynamics of social contexts (including individual behaviors, group dynamics and cultural factors) to stimulate learning in complex domains such as innovation and change management. Adopting a ‘learning by doing’ philosophy, experiences conducted over the last(More)
An important focus in current research on decision support systems (DSS) is the design of flexible environments to facilitate and support learning about the problem domain by the user. This research uses case-based reasoning to present a symbiotic DSS in which both the user and the DSS learn from each other. The user learns from the DSS (from stored prior(More)
Setting-up successful virtual communities represents an effective way for facilitating the circulation of knowledge in organizations and groups. However the design of such successful communities represents a main challenge that is principally related to the difficulty to engage people into a knowledge exchange process and to establish a sustainable level of(More)
