Challenges and Approaches to Engaging Stakeholders in Requirements Engineering
This event took place on Tuesday 25 October 2005 at 12:15
Prof. Pericles Loucopoulos Information Systems Group, School of Informatics, the University of Manchester, UK
A key challenge in the development of systems is the engagement of domain experts in their articulation, agreement, and validation of requirements. This challenge is particularly pronounced at the early requirements phase when multiple stakeholders from different divisions and often different organisations need to reach agreement about the intended systems. Decisions taken at this stage have a profound effect on the technical and economic feasibility of a project. The response of the Requirements Engineering community has been the introduction of a variety of conceptual modelling formalisms and appropriate requirements engineering processes. There is sufficient empirical evidence however that demonstrates the alienation of stakeholders from such notations and processes. The possible acquiescence of stakeholders approving a specification, without a deeper understanding of the modelled system, can lead to potentially profound problems due to differences between the expected value from the target system and that which is finally delivered. This talk will explore issues, challenges and approaches associated with capturing of, negotiating about and agreeing on early requirements from a design stance, using examples from large scale industrial applications.

Semantic Web and Knowledge Services is...
Our research in the Semantic Web area looks at the potentials of fusing together advances in a range of disciplines, and applying them in a systemic way to simplify the development of intelligent, knowledge-based web services and to facilitate human access and use of knowledge available on the web. For instance, we are exploring ways in which tnatural language interfaces can be used to facilitate access to data distributed over different repositories. We are also developing infrastructures to support rapid development and deployment of semantic web services, which can be used to create web applications on-the-fly. We are also investigating ways in which semantic technology can support learning on the web, through a combination of knowledge representation support, pedagogical theories and intelligent content aggregation mechanisms. Finally, we are also investigating the Semantic Web itself as a domain of analysis and performing large scale empirical studies to uncover data about the concrete epistemologies which can be found on the Semantic Web. This exciting new area of research gives us concrete insights on the different conceptualizations that are present on the Semantic Web by giving us the possibility to discover which are the most common viewpoints, which viewpoints are mutually inconsistent, to what extent different models agree or disagree, etc...
Our aim is to be at the forefront of both theoretical and practical developments on the Semantic Web not only by developing theories and models, but also by building concrete applications, for a variety of domains and user communities, including KMi and the Open University itself.
