| Title: | A DEMPSTER-SHAFER MODEL OF RELEVANCE |

| Abstract: | We present a model for representing relevance and classification
decisions of multiple catalogers in the context of a hierarchical
bibliographical database. The model is based on the Dempster-Shafer
theory of evidence. Concepts like ambiguous relevance, inexact
classification, and pooled classification, are discussed using the
nomenclature of belief functions and Dempster's rule. The model thus
gives a normative framework in which one can describe and address many
problematic phenomena which characterize the way people classify and
retrieve documents. |
