Network Structure of Folksonomies

Network Structure of Folksonomies

This video was recorded at 4th European Conference on Complex Systems. Folksonomies can be viewed as three mode graphs or as graphs made up of nodes (tags, users, resources) connected by hyper-edges. I shall report on some network statistical properties of a folksonomy graph based on data collected for the del.icio.us system. Moreover, by introducing a suitable distance between resources based on tag co-occurrence, I shall show that folksonomies embed a meaningful semantic clusterization of resources.
