Signed graphs contain different types of relations towards actors in SNA. The assignment of a positive or negative relationship finds its roots in structural balance theory. The mathematical formalization of this concept was later added by Harary (1953) and Cartwright ( 1956, 1979).

Subdividing actors into prespecified homogeneous blocks provides for the analysis of such network data related to internal and external characteristics.
