Common wiki applications lack possibilities to structure the
relationships between wiki pages. This paper presents a semantic wiki prototype
named SHAWN that allows modelling concepts and their relationships within a
wiki environment. One goal of this prototype is to keep concept creation very
simple. Yet, entering relationship data instantaneously gratifies the user with
enhanced navigational means on the wiki. The engine supports simple semantic
queries upon the emergent model. A challenge is to accommodate a self-explaining
query interface for these ontologies.
