Problems solved by technology

However, the existing evaluation methods are often simply based on the total number of citations of scholars or the simple co-author network of papers, and these methods do not take into account the mutual enhancement of the influence of papers and scholars and the influence of time on the influence of papers. influences

Embodiment Construction

[0031] In order to make the purpose, technical solution and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below.

[0032] The example of the present invention provides a method for evaluating the influence of scholars based on academic heterogeneous networks, which includes:

[0033] Step 1: Extract the citation relationship of the papers and the corresponding author of each paper, publication time and other information from the APS and DBLP datasets to form a paper citation network.

[0034] The differences between the two datasets are compared as follows:

[0035]

[0036] Among them, we selected a total of 23,365 papers in the fields of DataMining and Artificial Intelligence from the DBLP dataset from 1990 to 2013 during the specific implementation of this program.

[0037] According to the mutual citation relationship between papers, a paper citation network is constructed. ...

Abstract

The invention discloses a scholar-influence evaluation method based on an academic heterogeneous network. According to the method, interaction and communication of academic subjects are analyzed in a dissertation-scholar heterogeneous network, and when the dissertation-scholar heterogeneous network is used for evaluating the influences of scholars, reference relations between a PageRank algorithm and dissertations are used for distinguishing the importance of the dissertations. Meanwhile, in consideration of the characteristic that the number of citations that the dissertations receive needs time to be constantly accumulated, according to the published time of different dissertations, time functions are added, the PageRank algorithm is improved, and the influence of the published time on the dissertation importance is intensified. On the basis of the analysis, the method can evaluate the influences of the scholars in the dissertation-scholar heterogeneous network by a random walk algorithm so that the accuracy and the reliability of the scholar-influence evaluation can be improved, and providesa basis for the scholar-influence evaluation, the examination and approval of scientific-research awards and funds, and other tasks.

Description

technical field [0001] The invention relates to a method for evaluating scholar influence based on academic big data in the academic field, and in particular to a method for evaluating scholar influence based on a time function under a paper-scholar heterogeneous network. Background technique [0002] Scientific research is a part of human activities that cannot be ignored, and the development of human beings is inseparable from the rapid development of scientific research. Research activities are an important aspect of computational social science. Typical scientific research activities are mainly carried out by scientific researchers, who publish academic papers in academic journals and conferences. Academic influence is an evaluation index to measure the quality and importance of a scientific research subject's work. Correctly evaluating a scientific researcher's scholarly influence can provide a reference for the approval of scientific research funds and the evaluation ...
