Research on the construction and application of short video evaluation system for scientific and technological journal papers in China

Abstract: Purposes  The short videos of scientific and technical journal papers on China's commonly used video media platforms are evaluated to provide reference for improving the quality of academic short videos and promoting scientific and technical journal papers for short video dissemination. Methods On the basis of using the questionnaire survey method to understand the audience's viewing habits and preferences for short videos of sci-tech journal articles, combined with the dissemination requirements of sci-tech journal articles and the characteristics of short videos, constructed the short video evaluation indexs model of scientific and technological journal articles, and used the analytic hierarchy process to assign weights and a video evaluation model for sci-tech journal articles is constructed to comprehensively evaluate short videos of sci-tech journal papers.  Findings  The short video evaluation system for sci-tech periodical papers includes four levels: content production, overall effect, video elements, and communication channels, corresponding to 17 evaluation indexes, which label, color, title, ending and so on, video title, soundtrack, color, cover, commentary, and other indicators are the main factors affecting the viewing of video of scientific journal papers. The scores of the four video production comprehensive modes from high to low are as follows: article narration(3.96), animation(3.42), experiment sharing(3.16), and author self-narration(3.00).  Conclusions The article narration mode is currently the mode with the highest average score in the comprehensive evaluation of short videos of sci-tech journal papers,which relatively simple to produce and has complete video elements. This mode worthy of being adopted by journals in the process of dissemination practice. Although animation short videos are difficult to produce and are selective for the content of the paper, they have a good viewing impression and dissemination effect, and are worth trying for sci-tech journals with suitable content. It is proposed to learn from the short video cases of excellent knowledge, clarify the content advantages, improve the communication matrix and improve the awareness of new media communication of relevant personnel to promote the video dissemination of sci-tech journal papers.
