Problems solved by technology
However, it may take a long time for a paper to be cited from being accepted. Therefore, these measurement methods have a time lag problem. Accurate Assessment Results
In addition, Altmetrics measures the social influence of papers from the perspective of social networks, but this method is to obtain the scores of user mentions, readers, news reports, and government adoption from seven social platforms, and finally the paper with the higher comprehensive score , the greater its social influence
However, this method considers external information to evaluate the influence of papers, and has not been applied to the evaluation of the influence of papers in all fields, which will lead to lower influence values for those papers that have not been discussed on social platforms. Overstating the value of important papers, but also ignoring the importance of the citation relationship of the paper itself in evaluating its influence
In addition, the PageRank method is also used to measure the influence of nodes, but this method considers the influence of the node itself and the influence of neighbor nodes. The asymmetry of citations between groups leads to large errors in the accuracy of the paper's influence measurement
It can be seen that the existing methods for measuring the influence of papers have problems such as time lag, field limitations, and inaccuracy.

Embodiment Construction
[0042] In this example, if figure 1 As shown, a paper influence measurement method under an asymmetric information network includes the following steps:
[0043] Step 1. Construct a paper citation network for the citation relationship between papers;
[0044] Obtain n papers and use them as nodes to construct a collection of paper nodes, denoted as U={u 1 ,...,u i ,...,u j ,...,u n},u i is the ith paper node, u j It is the jth paper node, 1
[0045] with R ij Represents the i-th paper node u i and the jth paper node u j The relationship between; setting R ii = 1, indicating the i-th paper node u i There is a reference relationship with itself; if R ij =1, it means the i-th paper node u i The jth paper node u is referenced j ; if R ij = 0, it means the i-th paper node u i The jth paper node u is not cited j ; Thus, the n×n-dimensional paper citation matrix R shown in formula (1) is obtained and a paper citation n...

The invention discloses a paper influence measurement method under an asymmetric information network. The method comprises the following steps: 1, constructing a paper reference network; 2, dividing group distribution in the thesis reference network by using a community detection Louvain method to obtain a community set; 3, constructing a reference network in the communities and a reference network between the communities; 4, measuring the paper local influence of the reference network in each community and the community influence of the reference network among the communities by using a PageRank clustering method; and 5, measuring the influence of the paper in the paper reference network according to the local influence of the paper and the influence of the community where the paper is located. According to the method, the influence of the papers in a full-paper system and related domain groups can be effectively measured, so that the accuracy of paper influence measurement is improved.
Description
technical field [0001] The invention relates to a method for evaluating the influence of papers in the academic field, in particular to a method for measuring the influence of papers under an asymmetric information network. Background technique [0002] Scientific research papers are the complex research results of many scholars. How to measure the influence of papers has always been a concern of the academic community, but it is difficult to give a clear definition for different evaluation methods. At present, the methods of measuring the influence of papers are mainly based on the number of citations of papers, such as H index, G index, I10 index, H5 median, etc. There are also some methods that additionally consider the number of journal papers and impact factor indicators on the number of paper citations etc., such as H5 indicators. However, it may take a long time for a paper to be cited from being accepted. Therefore, these measurement methods have a time lag problem....
