In this paper we propose a new approach to represent entity semantics of loosely coupled systems by maintaining the topological neighborhood of context relations in a particular domain by a self organizing Kohonen map. We discuss how this technique can be applied to a distributed information system in order to find the most promising site to answer a particular query. Moreover, we show the applicability of our approach to any other system whose context can be described by certain semantical features. In general, our representation method can be seen as a kind of semantic distribution schema applicable for loosely coupled systems of various types — i.e., where systems can be information systems as well as databases or Internet-sites.
