A Context-Based Approach for Supporting Knowledge Work with Semantic Portals
Abstract
Knowledge work can be characterized by a high degree of variety and exceptions, strong communication needs, weakly structured processes, networks and communities, and as requiring a high level of skill and expertise as well as a number of specific practices. Process-oriented knowledge management suggests to focus on enhancing efficiency of knowledge work in the context of business processes. Portals are an enabling technology for knowledge management by providing users with a consolidated, personalized interface that allows accessing various types of structured and unstructured information. However, the design of portals still needs concepts and frameworks to guide their alignment with the context of persons consigned with knowledge-intensive tasks. In this context the concept of knowledge stance is a promising starting point. This paper discusses how knowledge stances can be applied and detailed to model knowledge work and support to support it with semantic context-based portals. We present the results from implementing a portal prototype that deploys Semantic Web technologies to integrate various information sources and applications on a semantic level and discuss extensions to this portal for the support of knowledge stances.
