Statistical methods for estimating quartiles of scientific conferences

Full Text

1. Introduction As it is known [1], quartile (quarter) is a category of scientific publications, which is determined by bibliometric indicators reflecting, first of all, the level of citation, that is, the relevance of the publication by the scientific community. And if the procedure for assigning quartiles to scientific journals has long been developed and successfully applied in practice [2-5]. In addition, many metrics have been introduced to assess the impact of journals, such as impact factor, 5-year impact factor, immediacy index, and impact factor without self cites, median impact factor, aggregate impact factor and others [6]. At the same time, this issue remains the subject of research for scientific conferences [7-11]. Some rating agencies have already begun to rank scientific conferences without disclosing the details of this procedure. For example, there is a CORE conference ranking [12], a CCF conference ranking [13], and a Microsoft Academic conference ranking (has been deleted) [14]. The disadvantages of the first two ratings are that they are expert, regional and do not fully disclose the procedure for ranking conferences. They also rank only computer science conferences. Researchers use various methods to compile new conference rankings, such as correlation analysis [7, 15], statistical analysis [15, 16], calculation of indicators similar to journal ones [9], graph and tree analysis [8, 17], regression analysis [16], [11]. Many of these studies involved the use of several of the listed methods. There were also works devoted to the search for methods for predicting the rating of a conference or predicting the impact of works presented at a particular conference [18]. Machine learning was used for these purposes [19, 20]. Therefore, this study is devoted to comparing two popular methods for predicting conference rankings, and I also included in the study such a statistical method as discriminant analysis, which is essentially a mathematical prerequisite for machine learning. We managed to find data on some conferences via the Internet, including their quartiles and a number of other indicators, which will be discussed below. As a result, we received a training sample from 23 conferences, on the basis of which we will try to assess the adequacy of the quartiles exposed using three methods of multidimensional statistical analysis: linear regression, discriminant analysis and neural networks. © Ermolayeva A.
