Fig. 2From: On the role of network topology in German-Jewish recommendation letter networks in the early twentieth centuryResults of semi-supervised analysis on undirected line graph \({\mathcal {L}} ^{\prime}\) using the harmonic function classifier by Zhu et al. (2003) and local and global consistency classifier by Zhou et al. (2003). For comparison, the same classifiers were run on \({\mathcal {L}} ^{\prime}\) with shuffled success labels and on randomized networks where the node degrees of \({\mathcal {L}} ^{\prime}\) are approximately preserved in expectationBack to article page
