Reasoning about multi-agents systems at the knowledge level allows us to abstract away from many concrete details of the systems we are considering. Fagin et al. introduced two notions to facilitate designing and reasoning about systems in terms of knowledge. The first notion is that of knowledge-basedprograms. Knowledge-based programs are defined as syntactic objects: programs with tests for k...

The predominant mechanisms for helping users find products in electronic catalogs are hierarchical navigation and text-based searches. Advanced electronic product catalogs also offer support for feature-based search or interactive product configuration. However, these search mechanisms are only appropriate if the space of products to be presented conforms to a number of simplifying restrictions...

The paper analyzes management practices as reflexive practices based on transactive knowledge (Brauner, 2002). It relates the concept of transactive knowledge systems to central concepts of structuration theory (Giddens, 1984), namely structuration and the duality of structure. Structuration theory provides a practice-based foundation of the concept of transactive knowledge systems. It sheds li...

Increasing market demands concerning customer requirements and market pressure from competitors force several enterprises to diversify their product range. Offering more and more product variants has the implicit impact of growing development process complexity. Although many configuration problems can be solved with knowledge-based configuration, the usage of configuration tools is very often ...

Our research on knowledge management is rooted in the community perspective. We believe that knowledge systems should serve primarily to help people create and share new knowledge. But we also acknowledge the role of stable, structured and reliable information, both as a component of our systems and as a component of the organizations within which we work. The contribution of the paper is a fra...
