Abstract

We study the behavior of the clustering coefficient in tagged networks. The rich variety of tags associated with the nodes in the networks we considered provide additional relevant information about the entities represented by the nodes. Such specific features can be important for practical applications like searching in the networks. Here we examine how the clustering coefficient changes when narrowing the network to a subgraph associated with a given tag, and how it correlates with various other properties of the subgraph. A further question addressed in our paper is how the clustering coefficient of the individual nodes is affected by the tags on the node. We argue that this kind of analysis can be useful when one is aimed at a detailed description of the structure of large complex systems.
