Knowledge Management (KM) has been a predominant trend in business in the recent years. Scalingup research prototypes to real-world solutions usually requires an application-driven integration of several basic technologies, e.g., ontologies for knowledge sharing and reuse, collaboration support like CSCW systems, and personalized information services. Typical characteristics to be dealt with are: manifold logically and physically dispersed actors and knowledge sources, different degrees of formalization of knowledge, different kinds of (web-based) services and (legacy) systems, and possible conflicts between local (individual) and global (group or organizational) goals. In order to cope with the inherent complexity of a more comprehensive solution, the concept of Agent-mediated Knowledge Management (AMKM) deals with collective aspects of the domain in an attempt to cope with the conflict between desired order and actual behavior in dynamic environments. Inherent to AMKM is a social layer, which structures the society of agents by defining specific roles and possible interactions between them. In this workshop we invite contributions which illustrate methodological, technical and application aspects of Agent-mediated Knowledge Management. Another important issue in AMKM concerns communication. In heterogeneous KM systems, knowledge sharing is hampered by the lack of common ontologies. Therefore, adequate support fo
