Interest and Expertise
Data and knowledge management is a research group within the School of Electronics Computer Science at University of Westminster. The group aims to foster research in specialised domain data integration and management, agent based management systems and in methods for intelligent decision systems in particular for intelligent patient management systems.
The Data & Knowledge Management research field comprises a range of practices used inside an organisation such as an enterprise, or the entire web to create, represent, share and make available knowledge and data, which are relevant for pursuing the organization's goals. It is an interdisciplinary research field on the border between computer science, businesses, and mathematics. We contribute to the above research area by developing: methodologies and tools to support the elicitation of knowledge and its encoding in computer interpretable formats, formalisms, architectures and tools for knowledge representation, reasoning and discovery. We also focus on intelligent architectures and tools for the integration of data and knowledge sources and the delivery of efficient and scalable services
