“…In a similarity network, the nodes (vertices) are all the tags whose valid status is 1, and if the similarity between two tags is bigger than a threshold determined by a group of experts or some kind of mechanism, then links an edge between the two tags. We can firstly conduct community detection, and then mine the star node in each community in such a network [32]. The star nodes and the isolated nodes in the network form a simplifying tag set.…”

Abstract. Summary extract of heterogeneous multimedia documents is an important content and requirement of information management at the Internet era. Though some summary extract approaches have been proposed in recent years, in general they can only be used in a single-type media. More important is that the existed approaches of multimedia summary extract had no satisfactory effects, and can't be brought into practice. Aiming at these problems, an approach based on folksonomy with incentive and quality assurance mechanisms is put forward. The proven folksonomy ensures the practicality of the approach, the incentive and quality assurance mechanisms avoid the innate problems of folksonomy: cold boot and inaccurate tagging. The experiment shows that the approach is reasonable and effective.
