Situation Theory and Dempster-Shafer's Theory of Evidence for Information Retrieval

We propose a model of information retrieval systems that is based on a Theory of Information and a Theory of Uncertainty, respectively Situation Theory and Dempster-Shafer’s Theory of Evidence. These were selected because they allow us to tackle two of the main problems that confront any attempt to model an information retrieval system: the representation of information and its flow; and the uncertainty engendered by the complexity and ambiguity arising when dealing with information.
