La resurrection des cliques: application du Treillis De Galois

The Ressurrection of Cliques: Àpplication of Galois Lattices. The mathematical definition of clique has never been entirely satisfactory when it comes to providing a procedure for assigning individuals to groups. This paper shows how the clique definition, when it is linked with Galois lattices, can be used to produce an intuitively appealing characterization of groups - one that is consistent with ethnographic descriptions. Two examples, using "classical" social network data sets, are provided.
