一种内容和引用特征融合的知识结构划分方法研究

A Division Method of Intellectual Structure of Combining Content and Citation of Documents

通过对现有知识结构划分方法的梳理,总结了当前的知识结构融合方法,用数据表明了融合文献的内容和引用特征进行知识结构划分的必要性。在此基础上,通过实验证明用最大值函数将文献的标题和摘要内容特征以及文献耦合引用特征融合进行知识结构划分的效果,并将其与现有方法进行对比。结果表明:该融合函数可以提高知识结构划分的精度。

Based on systematical investigation of existing methods of intellectual structure, this paper analyzes the current fusion method of intellectual structure, and shows the necessity of combining content and citation features of literature to divide intellectual structure with real data. On this basis, this paper conducts a research with experiments on the effects of maximum function dividing intellectual structure with the use of combining the content features of titles and abstracts of literature with cita- tion features of bibliographic coupling, and compares the method of experiments with existing methods. The results show that this fusion function has improved the accuracy of dividing intellectual structure. 2 figs. 4 tabs. 17 refs.
