| Abstract: |
| The document combing based method is one of the common ways in expert search area. However there are still many deficiencies about this approach. In this paper, the way to expand query based on dictionary is used to improve the expert search effectiveness. Through semi automatic construction of expertise vocabulary and the establishment of algorithm model of experts sorting and expertise suggestion, this paper takes the Expert Search System (WHU ES) as a platform to carry out expert search experiment in the field of library and information science. The results show that the use of expertise vocabulary can significantly improve the precision and the effectiveness of expertise recognition. 3 figs. 3 tabs. 10 refs. |
