The network was observed in a university karate club over three years, from 1970 to 1972, and published in 1977. The network describes association patterns among 34 members and maps out allegiance patterns between members and either Mr. Hi, the instructor, or John A., the club president, after an argument about hiking the price for lessons. The club had near 60 members at the time. The 34 in the network are those who met other members outside the club's classes and meetings, and the 'weight' of a tie is the number of contexts outside the club in which the two members met. The allegiance of each node is listed in the 'allegiance' node attribute, which takes the value 1 if the individual sided with Mr. Hi after the fight and 2 if the individual sided with John A.
