摘要：

针对专家库构建过程中出现的同名歧义现象, 提出一种基于多特征融合的同名专家消歧方法。从中国知网(CNKI)数据源中获取专家的论文信息, 抽取论文的标题、摘要、关键词、作者单位和合作者等关键信息, 并将其作为属性特征, 构建特征表示模型, 进而定义同名专家之间的相似度计算函数。根据计算得到的相似度, 将同名消歧问题转化为聚类问题。利用近邻传播聚类算法进行聚类, 解决同名消歧问题。在采集的专家论文数据上的实验表明, 基于多特征融合的同名专家消歧方法的准确率可达92%, 取得良好的消歧效果。

Abstract:

According to the expert ambiguity with the same name in the process of building expert database, an expert disambiguation method based on multi-feature fusion is proposed. The paper information of experts is obtained from data sources such as CNKI. Key information (title, abstract, keyword, affiliation and collaborator) is extracted. The feature representation model is constructed with these information as attribute features. The similarity calculation function between experts of the same name is defined. According to the similarity, the problem of disambiguation of the same name is transformed into clustering problem. Affinity propagation clustering algorithm is used to solve the problem of homonymy disambiguation. Experiments on the collected expert papers show that the accuracy of the same-name expert disambiguation method based on multi-feature fusion can reach 92%, and good disambiguation results are achieved.

Key words: multi-feature fusion, homonymy disambiguation, expert database, clustering algorithm, data collection
