    Modeling Information Retrieval with Probabilistic Argumentation Systems

    20th Annual BCS-IRSG Colloquium on IR

    Autrans, France. 25th - 27th March 1998


    J. Picard & R. Haenni


    Probabilistic Argumentation Systems (PAS) are a technique for representing uncertainty both symbolically and numerically.

    It is shown that this technique, which combines symbolic logic and probability, can be used as a general model of information retrieval.

    PAS provide a dual (symbolic and numerical) interpretation of the logical uncertainty principle, and are a flexible model for integrating various sources of information about query or document contents.
