摘要
Although users can self-generate personalized data for describing preferences more comprehensively, user-created data is not rigorous and uncontrollable, which leads to enormous data of low quality with serious noise. On managing complex network, more attentions should be placed on high quality information that has been or will be produced by experts who have knowledge in specific fields in order to avoid being restricted to written knowledge. This paper finds experts by constructing and analyzing interest profiles of users and proposes a screening method for detecting abnormal pseudo-experts. Due to the small number of authoritative experts in networks, which provide a limited amount of information, experts defined in this paper not only include authoritative experts, but also ordinary users that have a lot of knowledge in a certain field. Experiments illustrate the correctness and effectiveness of the algorithm, and the low complexity renders it suitable in handling massive user node information. ©, 2015, Chinese Institute of Electronics.
