摘要
现有文献相关度多是基于单一特征的局部相似判断,易造成相关文献的低信度、高冗余。本文从文献共引、耦合、共篇3个维度出发,提出并实现了一种综合三特征项的文献相关度判定方法。现有实验初步表明该方法具有较强的适用性。
Currently, the judgment of literature relativity is mostly based on the local similarity of a single feature, which leads to the low reliability and high redundancy of the related literatures. Proceeding from the 3 dimensions of co-citation, bibliographic coupling and co-literature, this article proposes and implements a literature relativ- ity judgment method which integrates the 3 characteristic items. The experiment preliminarily verifies the validity of the method.
