Abstract

The invention belongs to the technical field of wireless communication networks and particularly discloses a crowd portrayal system and a crowd portrayal method based on a microblog label. The system comprises two main modules of a microblog label recommendation module and a label theme clustering module; the first module adopts a label recommendation algorithm covering three steps, wherein a first step is homogeneous label recommendation, a second step is co-occurrence label extension, a third step is that a semantic network is built on the basis of a Chinese mapping knowledge domain, the semantic similarity between labels is measured by using a network topology property, the labels with same or similar semantics are thus removed, and the refining property of the label used for portraying a user is ensured. According to the system and the method, the condition that the commercial application value of the label of the microblog user is wide is utilized, and the research direction is indicated for the mining algorithm of labels of internet users and the application of the Chinese mapping knowledge domain.
