Abstract

The invention discloses a sorting model and sorting method for papers, authors and periodicals oriented to scientific and technological documents, belonging to the field of digital libraries. According to the characteristics of the scientific research literature network, the present invention proposes a PAJ model, which is a directed graph, including three nodes of papers, authors, periodicals or conferences and five relationships among the three nodes. The invention also proposes a sorting method based on the PAJ model, which includes: extracting scientific research literature entities; establishing a PAJ model; generating a transition probability matrix; calculating the matrix and generating results. The algorithm uses matrix iterative calculation to achieve a convergent result, which is used as the basis for ranking, which can fully tap the internal relationship of the scientific research literature network, and the ranking results of each entity are accurate and credible.

Description

technical field [0001] The invention provides a sorting model and a sorting method of scientific and technological documents, belonging to the field of digital libraries. Background technique [0002] A research literature network is a network of authors, papers and journals or conferences such as figure 1 As shown, in this network, the author writes the article, and the article is published in the corresponding journal or conference, and at the same time, there is a mutual citation relationship between the articles. [0003] Scientific researchers need to consult a large number of papers in order to carry out research work. How to choose important journals or conferences, as well as influential papers of important authors for research, is an important part of scientific research. [0004] So far, the existing technologies on the scientific research literature network include: [0005] 1. ArnetMiner prototype system (http: / / www.arnetminer.org / ) developed by Tang Jie and o...
