We study a subset of the movie collaboration network, http://www.imdb.com, where only adult movies are included. show that there many benefits in using such which can serve as prototype for studying social interactions. find strength links, i.e., how times two actors have collaborated with each other, is an important factor significantly influence network topology. see when we link all same becomes small-world, lacking proper modular structure. On other hand, by imposing threshold on minimum number links should to be our studied subset, topology naturally fractal. This occurs due large meaningless namely, connecting did not actually interact. focus analysis fractal and properties this resulting renormalization group characterize self-similar structure these networks.
