Sampson (1969) recorded the social interactions among a group of monks while resident as an experimenter on vision, and collected numerous sociometric rankings. During his stay, a political ``crisis in the cloister'' resulted in the expulsion of four monks (Nos. 2, 3, 17, and 18) and the voluntary departure of several others - most immediately, Nos. 1, 7, 14, 15, and 16. (In the end, only 5, 6, 9, and 11 remained). Of particular interest is the data on positive affect relations (``liking''), in which each monk was asked if they had positive relations to each of the other monks.
The data were gathered at three times to capture changes in group sentiment over time. They represent three time points in the period during which a new cohort entered the monastery near the end of the study but before the major conflict began.
Each member ranked only his top three choices on ``liking''. (Some subjects offered tied ranks for their top four choices). A tie from monk A to monk B exists if A nominated B as one of his three best friends at that that time point.
samplike is the time-aggregated network.
It is the cumulative tie for ``liking'' over the three
periods. For this, a tie from monk A to monk B exists if A
nominated B as one of his three best friends at any of the
three time points.
The graph is stored as an network objects.
It has three vertex attributes:
Groups of novices as classified by Sampson: ``loyal'', ``outcasts'', and ``Turks''. There is also an interstitial group not represented here.
An indicator of attendance the minor seminary of ``Cloisterville'' before coming to the monastery.
The given names of the novices and their IDs in the original dataset.
In addition, it has an edge attribute, nominations, giving the
number of times (out of 3) that monk A nominated monk B.
This data set is standard in the social network analysis literature, having been modeled by Holland and Leinhardt (1981), Reitz (1982), Holland, Laskey and Leinhardt (1983), and Fienberg, Meyer, and Wasserman (1981), Hoff, Raftery, and Handcock (2002), etc. This is only a small piece of the data collected by Sampson.
This dataset was updated for version 2.5 (March 2012) to add the cloisterville variable and refine the names. This information is from
de Nooy, Mrvar, and Batagelj (2005).
The original vertex names were:
Romul_10, Bonaven_5, Ambrose_9, Berth_6, Peter_4, Louis_11, Victor_8, Winf_12, John_1, Greg_2, Hugh_14, Boni_15, Mark_7, Albert_16, Amand_13, Basil_3, Elias_17, Simp_18.
