### Generalized Blockmodeling

Generalized Blockmodeling is a concept developed by the Slovenian mathematician Vladimir Batagelj. An extensive presentation, *V. Batagelj, A. Ferligoj, P. Doreian: Generalized blockmodeling* (SFI/SAS workshop: The dynamics of groups and institutions. Brdo pri Kranju, Slovenia, 7.-11. June 2004), is available online.

**Blockmodeling as a clustering problem**
*The goal of blockmodeling is to reduce*
a large, potentially incoherent network
to a smaller comprehensible structure
that can be interpreted more readily.
Blockmodeling, as an empirical procedure, is based on the idea that units in
a network can be grouped according to
the extent to which they are equivalent,
according to some meaningful definition of equivalence.
(page 5 of the June 2004 presentation)

Blockmodeling could be used to simplify Xholon networks, and to automatically derive hierarchical structure.

A related paper is *Role Models for Complex Networks* by Jorg Reichardt and Douglas R. White.
