USING GALOIS LATTICES TO REPRESENT NETWORK DATA
SOCIOLOGICAL METHODOLOGY 1993, VOL 23
23: 127-146 1993
Galois lattices are introduced
as a device to provide a general representation for two mode social network
data. It is shown that Galois lattices yield a single visual image of such data
in cartes where most alternative models produce dual images. The image provided
by the Galois lattice produces, moreover, an image that can suggest useful
insights about the structural properties of the data.
An example, based on data from Davis, Gardner, and Gardner (1941), is used to
spell out in detail the kinds of structural insights that can be gained from
this approach. In addition, other potential applications are suggested.
