Abstract

Total or partial duplication of documents affects the effectiveness of the visualization of search results. In this paper we propose a navigation strategy that sorts a list of documents such that the first documents contain more information content decreasing considerably duplication. The strategy defines a content relation between documents based on their equivalence and omission and estimates the new information content obtained from visiting documents. In this paper, we describe the strategy and experimentally evaluate it. These results indicate the potential use of this strategy for the visualization of thematically related documents that are relevant to a query. © Springer-Verlag Berlin Heidelberg 2007.
