| EIES {netdata} | R Documentation |
This is a network collected by Freeman & Freeman (1980) and described in the text Wasserman & Faust (1994).
The network relates acquaintanceship among a group of researchers recorded at two time points, one before, and one seven months after the introduction to the then novel phenomenon of communication by computer based on the pioneering Electronic Information Exchange System (EIES). EIES afforded what we would call today ``newsgroups" (collective discussions for the entire group), and more selective ``electronic mail" (one-to-one or one-to-many). Acquaintanceship was recorded on each pair of researchers on a five-point scale.
Of the 32 researchers involved, information is available on the number of citations in the year of the data collection, and on their primary discipline. These attributes were dichotomized, defining two equal-sized groups of much and little cited authors (with at least, respectively fewer than 12 citations), and defining a group of sociologists and a mixed group consisting of researchers educated in anthropology, psychology, communication, and statistics.
These data sets are known as the EIES data.
Complete descriptions of these data, including references for the original sources of the data, can be found in Chapter 2 (pages 59- 66) and Appendix B (pages 738-755) of Wasserman and Faust.
The original data in ASCII, UCINET and KrackPlot formats are available at INSNA.

The data set is comprised of five networks:
eiesacq1 is a network of 48 researchers with a edge value called
acquainted representing the level of friendship at time 1. It is coded
4=close personal friend, 3=friend, 2=person I've met, 1=person I've heard of,
but not met, 0=unknown name or no reply.
There is a vertex attribute called messages indicating if they are in the selected 32
researchers.
eiesacq2 is the same network of 48 researchers at time 2 with the
edge value acquainted representing the level of friendship at time 2.
There is a vertex attribute called messages indicating
if they are in the selected 32 researchers.
eies1 is the network among the subset of 32 researchers at time
1 with the edge value called acquainted.
There are vertex attributes called field for their
primary discipline and an indicator called citation for highly cited
researchers.
eies2 is the same network of 32 researchers at time 2 with the
same attributes.
eiesmessages is the network among the subset of 32 researchers
with the edge value called messages being the count of the number of
messages sent.
There are vertex attributes called field for their
primary discipline and an indicator called citation for highly cited
researchers.
We have also dichotomized the level of friendship
defining the relation as being a friend or
close friend.
eies1friend is the network among the subset of 32 researchers at time
1 of friends or close friends (i.e., acquainted > 2).
There are vertex attributes called field for their
primary discipline and an indicator called citation for highly cited
researchers.
eies2friend is the same network of 32 researchers at time 2 with the
same attributes.
