Abstract

It is important to reveal the mechanisms of propagation in different cognitive networks. In this study, we discuss the k-clique percolation phenomenon as related to the free association networks including the English Small World of Words project (SWOW-EN). We compared different semantic networks and networks of free associations for various languages. Surprisingly, k-clique percolation for all [Formula: see text] 6-7 is possible on free association networks of different languages. Our analysis suggests new universality patterns for a community organization of free association networks. We conjecture that our result can provide a qualitative explanation of Miller's [Formula: see text] rule for the capacity limit of working memory. A new model of network evolution extending the preferential attachment is suggested, providing the observed value of [Formula: see text].
