Background and aim: Content analysis of scientific journals is a good method for becoming aware of the evolutionary flow of research strategies and data collection techniques used researchers in different fields. The aim of this study was to investigate the content analysis of Persian released articles from Iranian Knowledge and information science Journals in terms of research strategies and data collection techniques.Material and methods: This study was conducted using content analysis method. The data collection technique was checklist and document observation. The study population included 943 Persian articles published in the field of Knowledge and Information Science in scientific-research and peer-reviewed Iranian Journals during 2005-2009. Data were entered to SPSS software and analyzed by using descriptive statistics and Chi-square formula.Findings: the study showed that citation (42.71%) and survey (37.63%) methods were the most popular methods used by the Iranian researchers in the field of Knowledge and Information Science. The most common technique for data collection was citation (50.44%) and questionnaire (25.63%) among researchers, respectively. Chi-square indicated that there was a significant difference between scientific-research and peer-reviewed journals based on research methods and data collections techniques.Conclusion: Study of the published articles indicated the asymmetric distribution of research methods and data collection techniques used in knowledge and information science field.

Background and aim: Number of scientific products indexed in the major databases such as Web of Science is one of the important criteria for ranking countries. This research aimed to review the Iranian articles in the field of microbiology in terms of quantitative and qualitative indicators of the growth rates of self-citations.Material and methods: In this research, citation analysis method was used. WoS database was selected for data collection and citation report of this database and Excel software were applied for data analysis.Findings: Based on the findings, 763 microbial articles of Iranians researchers were indexed in Web of Science database. The average of annual growth rate was 57.25%. Average of citations annual growth rate without considering self-citation was 23.54. Average of annual growth rate of journal impact factors with self-citation and without self-citation was -8.51 and -8.93, respectively. Moreover, the average of annual growth rate of immediacy index was -10.1.Conclusion: The results showed that Iran has had increasing and decreasing trends in the field of microbiology in terms of quantitative and scientometric qualitative indicators in recent years.

Background and aim: The aims of this study was to compare the scientific productions of Iran in the field of education with competitor countries in the Middle East (Turkey, Saudi Arabia, Pakistan, Egypt and Israel) based on published articles in the Web of Science database from 2003 to 2012.Material and methods: Research method was scientometrics. Data was extracted from the WoS database. Totally, 4716 articles were retrieved with writing the research formula in advanced research, selecting three indexes of scientific citation, social sciences, art and humanities. The statistical population consisted of all of the scientific productions of 6 countries; Iran, Turkey, Saudi Arabia, Pakistan, Egypt, Israel in the field of education sciences. Excel and SPSS software were used to analyze the data.Findings: The results showed that the amount of the scientific productions of Iran in the field of education was 1046 articles from 2003 to 2012, and the highest one was belonged to Education with 529 articles and Educational Technology with 28 articles was the lowest amount in these productions.Conclusion: The scientific productions of Iran in the field of education have increasingly grown during 10 years so that Iran is located after Turkey with 31.6 percent growth.

Background and aim: Presenting e-services via NAJA websites will significantly save time and cost for users. The aim of this study was to survey on visibility of NAJA websites, rank and relate these websites based on link interaction together and identifying core websites of these organizations.Material and methods: Current research as a webometrics method evaluated the links among I.R Iran police websites by using links analysis. In order to identify and introduce the core websites, Au = t/n formula was used.Findings: Findings reveal that NAJA websites are weak in terms of links and collaboration. Current study indicates that 2 websites of Rahvar Police and NAJA Police are core websites of I.R Iran police.Conclusion: Since NAJA websites have common contents, if they exchange the links with together, their visibility will be increased.

Background and aim: Reviewing the trend of scientific products in the field of Evidence-Based Medicine is essential in order to plan for improving the status and research priorities of the state. The purpose of this study was to determine the status of scientific products in the field of Evidence-Based Medicine (EBM).Material and methods: This applied study was conducted using a scientometric method. The samples were all scientific productions indexed by 'EBM' in Scopus database from 1939 to 2014. Data collection tool was Scopus database. The obtained data was analyzed using ‘Excel’ software.Findings: Findings showed that the status of scientific products of the world in the field of Evidence-Based Medicine has descended in recent years so that the number of produced documents has been very small from 1939 to 1992. It has been increased from 1992 to 2007 and from 2011 to 2012 and decreased from 2007 to 2011 and from 2012 to 2014. No work has been published in the field of 'EBM' in 1963, 1964, 1965, 1966, 1968, and from 1940 to 1961.Conclusion: With a production of 258 documents, Iran is ranked 37 among the 160 participating nations. This rank is very low compared to the competing states.

Background and aim: The aim of this study was to determine the co-authorship condition of chemistry researchers in University of Yazd in Web of Science database.Material and methods: This scientometric study was performed to visualize the co-authorship networks. For data description, Spss and Ravar- matrix software were used and Ucinet and Net draw software were applied to analyze the data.Findings: The density of co-authorship network was 0.0288 and the results showed that researchers who had high frequency had strong correlations among the faculty members of Yazd University, too.Conclusion: In general, It can be concluded that there are no many connections between relationships that constitute co-authorship network among faculty members of Yazd University and there is not a high coherence among their co-authorship networks.

Background and aim: Self-citation is an important challenging issue in evaluating the scientific outputs. The aim of this study was to assess analytically the relationship between the quality and self-citation in Persian Humanities Journals based on Persian Journal Citation Reports (PJCR) in the Islamic World Science Citation Center (ISC).Material and methods: Citation analysis method was used in the present study and 67 Persian Humanities Journals indexed in the ISC database with impact factor.Findings: The results showed that the average self-citation rate for humanities sciences journals with selected impact factors in 2010 was 24.45% in 2001- 2010. After analytical assessment of 67 reviewed journals, 23 of them had self-citation rate of 20% and less than 20%, and 20 of them had self-citation rate of more than 20%. Furthermore, results showed that the Impact Factor, Immediate Index, Matthew Value and the Proportion of Citing to their Articles with eliminating the effective self- citation in the four and combined indicators had decrease, increase and no changes in 65.91%, 19.35% and 14.72% of journals, respectively. In addition, with eliminating the self- citations, the citation value of 56.51% of the journals decreased, of 32.78% had no changes and of 3.94% of the journals reached to zero.Conclusion: There was positive and significant relationship between the self-citation and the quality of journals. Therefore, it is needed to determine a policy for the rate of self-citation on the behalf of editorial board to reduce it and to cite by the other journals.

Background and aim: The aim of this study was to draw co-citation map of outstanding authors in the field of image retrieval based on articles indexed in ISI from 2001 to 2012.Material and methods: This scientometric study was performed using bibliometric techniques such as co-citation analysis. Samples of the current study were all articles indexed in ISI in the field of image retrieval from 2001 to 2012. Therefore, 2537 papers were retrieved in this field. Citespace and Webometric Analyst software were used to analyze the co-citation of authors.Findings: Results indicated that there were 84 co-citation links among 58 most cited authors in the network of co-citation authors. Tao DC and Zhang HJ reached the first rank with writing 26 articles. Rui Y was the most cited author with 627citations. Highest centrality, sigma and burst were related to Rui Y with 0.55, Smith JR with 20.63 and Dattar R with 42.71, respectively.Conclusion: Creating co-citation links among the authors of image retrieval shows the intellectual relevance among the authors of this field. It is obvious that none of the authors with high papers is an effective and most cited author and has the highest centrality, sigma and burst in the field of image retrieval.
