Homonymous author disambiguation method based on network representation and semantic representation

Abstract

The invention discloses a homonymous author disambiguation method based on network representation and semantic representation. The method comprises the following steps: 1) extracting semantic featuresand discrete features of each paper in a target paper library; 2) calculating the similarity among the papers based on the discrete features to obtain a relationship similarity matrix of the papers;if one paper and other papers do not have a co-author or institution, adding the paper and other papers into an outlier paper set; 3) calculating a semantic similarity matrix of the papers based on the semantic features of the papers; adding papers without semantic features in the target paper library into an outlier paper set; 4) performing weighted summation on the relationship similarity matrixand the semantic similarity matrix to obtain a paper similarity matrix, and clustering the paper similarity matrix; adding papers which do not belong to any cluster into the outlier paper set; and 5)distributing the papers in the outlier paper set to the corresponding clusters by utilizing a similarity threshold matching-based method. According to the method, high-accuracy disambiguation of authors with the same name of the papers is realized.

Description

technical field [0001] The present invention mainly relates to the field of entity disambiguation, heterogeneous network embedding technology, and word vector embedding technology, in particular to a disambiguation technology based on network representation and semantic representation of the same author of the paper. Background technique [0002] Same-name disambiguation has been regarded as a meaningful but challenging problem in many fields, such as document management, social network analysis, etc. In the field of academic network, the emergence of various academic search systems, such as Google Scholar, Aminer, etc., provide great convenience for the search of papers and academic communication. However, due to the huge number of papers and the complexity and variety of paper information, there is a problem that a large number of papers are assigned incorrectly. Among them, the ambiguity of authors with the same name is an important but thorny problem. The disambiguation...
