We investigate the similarities of pairs of articles which are co-cited at the different co-citation levels of the journal, article, section, paragraph, sentence and bracket. Our results indicate that the following similarities rise monotonically as the co-citation level gets lower (from journal to bracket), in order of importance: textual similarity, intellectual overlap (shared references), author overlap (shared authors), proximity in publication time. While the main gain in similarity happens when moving from journal to article co-citation, all levels entail an increase in similarity, especially the paragraph and sentence/bracket levels. We compare results from three journals over the years 2010-2015, Cell, the European Journal of Operational Research and Physics Letters B, with consistent general outcomes.

Abstract
We investigate the similarities of pairs of articles which are co-cited at the different co-citation levels of the journal, article, section, paragraph, sentence and bracket. Our results indicate that the following similarities rise monotonically as the co-citation level gets lower (from journal to bracket), in order of importance: textual similarity, intellectual overlap (shared references), author overlap (shared authors), proximity in publication time. While the main gain in similarity happens when moving from journal to article co-citation, all levels entail an increase in similarity, especially the paragraph and sentence/bracket levels. We compare results from three journals over the years 2010-2015, Cell, the European Journal of Operational Research and Physics Letters B, with consistent general outcomes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
