A Comparative Study Of The Differences In The Influence Of The Special Literature Of Different Disciplines On The Journals

As the carrier of academic dissemination and exchange,academic journals play a vital role in the sharing of scientific research results,the accumulation of scientific research experience and the promotion of scientific research progress.The influence of academic journals reflects the academic value and application value of scientific and technological achievements.The evaluation of academic influence of journals can help improve the internal quality of journals,and enable academic journals to enhance their core competitiveness under the situation of journal homogeneity.At the same time,a reasonable evaluation of academic journals can provide scholars with more scientific guidance in academic literature journal study,academic research,and submission,and also provide direction and focus for the management and decision-making of scientific research institutions.Through combing related researches,it is found that most of the existing studies regard documents with common research themes as thematic documents,and more often divide the journal documents into review documents,research documents and other documents,and use this as the research object.By comparing the average contribution rate,the contribution rate to IF and other indicators,explore the contribution of different document types to the impact factor of academic journals.The academic level of a journal depends on the level of each academic article published.At the same time,the composition,topic selection,and typesetting of journals are also important factors that affect the competitiveness of academic journals.Analyzing the difference in the influence of thematic literature and non-special literature on academic journals is helpful to the planning and design of subject journal topics and columns,increasing the concentration of journal content,attracting higher-quality manuscript sources,optimizing journal quality,and improving academic journals Core competitiveness.On the basis of previous studies,this research compares and analyzes the influence of different subject literature on Impact Factor,and explores the effect of different subject literature on the influence of academic journals.The main contents of this research are as follows:(1)Introduce the research background and significance of the impact evaluation of academic journals,sort out the current status of domestic and foreign related research and summarize its characteristics,introduce the content and methods of the research,and give the main innovation points of this research.(2)Explore the characteristics of thematic literature and non-thematic literature from the aspects of citation,download frequency average and median of the thematic literature and non-thematic literature.Visually compare the citation frequency of thematic literature and non-thematic literature from2015 to 2019 in terms of the upper and lower quartiles,medians,and upper and lower limits through box plots,and analyze the characteristics of data distribution to analyze thematic literature and The similarities and differences of non-thematic literature on the influence of journals.(3)Explain the influence of thematic literature on the Impact Factor from the fields of library and information science,journalism and communication,computer science,and chemistry.Compare the IF value of the journal before and after excluding the special literature,calculate the contribution of the special literature to the IF and the proportion of the special literature in the total paper,and analyze the influence of the special literature of different disciplines on the IF of the journal.On the basis of previous studies,this research explores the impact of different subjects on academic journals in terms of citation frequency,mean and median download frequency,changes in Impact Factor before and after excluding special articles,and the proportion of special articles in total papers.Influence.At the theoretical level,this study evaluates the journal's special literature,provides a new idea for evaluating the influence of academic journals,and makes the evaluation perspective more comprehensive.At the practical level,evaluating the influence of journals' special literature can provide effective information and services for journal management,decision-making,editing and other activities,and provide references for optimizing journal layout and setting of special topics,which can help reflect journal characteristics and improve journal quality.At the same time,it provides literature service organizations with criteria for selecting journals,strengthens library resource construction,and optimizes readers' reading services.
