Abstract
Objective: The aim of this study was to investigate the thematic structure and production process and growth of articles extracted from master's theses in knowledge and information science of Iranian public universities.
Methodology:The present study has examined articles from the beginning to the first half of 1398 through homogeneous analysis. 1425 dissertations were retrieved by searching the dissertation sites. Through the search of researchers, the titles of dissertations in the databases of "Meg Iran", "Normagz", "Science Search Engine", "Humanities Database", "University Jihad Database" and "Google Scholar" were retrieved 623 articles. Excel and Rover Prim software were used to analyze the bibliographic information of the articles and to analyze the homogeneity of the topics of the articles and to unify the keywords. Out of a total of 394 keywords, 59 keywords with a minimum frequency of 5 were selected using the Bradford's law and inclusion threshold to construct the co-occurrence matrix. Then, the created matrix was converted to UCNET software format, and maps and the value of degree, proximity and intermediate degree indicators were drawn and calculated through the software plugin, ie NetDraw
Findings: Findings showed that according to the indicators of intermediate centrality and rank, the highest value belongs to the topics of "academic libraries", "librarians", "knowledge management" and "scientometrics". Also, according to the Centrality of Proximity Index, the topics of "librarians", "academic libraries", "information literacy" and "knowledge management" have the most impact on the network. The growth trend reached its highest level in 1994 and 1995. Ferdowsi University of Mashhad with 100 titles and Shahid Chamran University of Ahvaz with 83 titles have the first and second ranks of nuclear universities among the universities that publish articles, respectively.
Conclusion: The greater focus of dissertation papers on scientometrics, knowledge management, librarians, information literacy, and academic libraries indicates the importance of these topics in postgraduate research.
