Network motif analysis of node triplets reveals detailed interaction patterns in directed networks of game bots and human users. a The 13 possible motifs composed of three nodes in a directed network. b The fractions of each motif type in each of the six networks. Those motifs that account for fewer than 18 % of all motifs are not shown. Friendship, whisper, mail, and shop of the game bot group, and friendship and shop of the human group show one dominant motif each, consistent with the high or low reciprocity found in the networks. c A closer look at the (normalized) Z-score triad census of party and trade networks where no dominant motif is evident; the Z-score method is employed to determine significantly over and underrepresented triangular motifs
