A Model for Representing and Retrieving Heterogeneous Structured Documents Based on Evidential Reasoning (1999)

Lalmas, Mounia

Documents often display an internal structure; they are composed of components. For example, a journal contains several articles, which themselves contain paragraphs, tables, etc. With structured...
