In both the original Wegman report and a subsequent follow-up paper by Yasmin Said, Wegman and two others, the background sections on social network research show clear and compelling instances of apparent plagiarism. The three main sources, used almost verbatim and without attribution, have now been identified. These include a Wikipedia article and a classic sociology text book by Wasserman and Faust. But the papers rely even more on the third source, a hands-on text book that explores social network concepts via the Pajek analysis software package – the same tool used by the Wegman team to analyze ‘hockey stick’ author Michael Mann’s co-author network.
