Combining Query Terms Extension and Weight Correlative for Expert Finding

摘要

This paper proposes two methods for solving the expert finding problem. In order to enhance the correctness, a C-value method is applied to these methods for query expansion. After query expansion, proposed system calculates correlation between all query terms and experts, and finally outputs a list of experts. The experiment results show that the proposed methods can provide higher precision than the baseline method from 3% to 10%.
