  We discuss in a compact way how the implicit relations between spatiotemporal
relatedness of information items, spatiotemporal relatedness of users, social
relatedness of users and semantic relatedness of information items may be
exploited for an information retrieval architecture that operates along the
lines of human ways of searching. The decentralized and agent oriented
architecture mirrors emerging trends such as upcoming mobile and decentralized
social networking as a new paradigm in social computing and is targetted to
satisfy broader and more subtly interlinked information demands beyond
immediate information needs which can be readily satisfied with current IR
services. We briefly discuss why using spatio-temporal references as primary
information criterion implicitly conserves other relations and is thus suitable
for such an architecture. We finally shortly point to results from a large
evaluation study using Wikipedia articles.
