Citation analysis plays an important role in research evaluation processes and their results are widely available to researchers for review and use. Citation is a scientific index that is used to evaluate the impact of science. The most important application of citation analysis is science policy making and research evaluation. In order to have a constant growth of coverage as well as to increase the accuracy in crediting for publication of large citation databases, the analysis of indexes of their scientific publications should be evaluated and reviewed by users and researchers to have appropriate measures for them. Scopus, WOS, and Mathscinet citation databases rank the journals using their own indexes and then classify them into four qualitative categories based on the quartile of their index. These categories represent the value of citing sources in the journals. One of the factors of choosing a journal to submit articles is the quality category or the ranking of that journal in citation databases. Therefore, the classification of journals is of great importance in terms of quality. The existing method in citation databases for categorizing journals is not a suitable method; Because from a statistical point of view, the statistical distribution of these indexes is not taken to find their quartile. In the research, we introduce citation databases in some related branches with references to their articles. In each database, the collection of journals is divided into four identical categories based on their indexes, which are: Q1 category includes journals with the highest value, Q2 category includes journals of the second category of values, Q3 categories include journals of the third category of values and Q4 categories include journals with the lowest value. These quadrants do not show the quality of the articles, but the quality of the journals in terms of citations. Scopus, WOS, and MathSicNet databases and their indexes are evaluated in the paper. The aim of this study is introducing the new methods for assessing the validity of journals in Scopus, WOS, and Mathscinet database. Also, the categories are compared by using descriptive statistics as well as different parametric and non-parametric statistical inference methods.

Using official and registration statistics and by referring to Scopus, WOS and Mathscinet databases, extract the list of journals along with their ranking index. In other words, in this research, census is used as a statistical survey method. Excel 2013 spreadsheet was used to data registry. After collecting the data, by using parametric (based on statistical distribution) and non-parametric methods, their quartiles were calculated according to specific index for each database and quartile quality categories were defined and journals were categorized accordingly. Then, by using the contingency table and the Kappa agreement coefficient, the agreement was measured. SPSS (version 23) software was used to perform the Kappa agreement coefficient test, and EasyFit (version 5.5) software was used to obtain the quartiles by parametric method using their distribution. In this way, the classification of the database is compared with the classification obtained from two non-parametric and parametric methods. The significance level of the tests throughout this research is set as 5%.

The classification of statistical and mathematical journals in MathSciNet database based on the parametric and non-parametric methods has been compared as well as in two fields, pure and applied. The results show that the p-value of the Kappa agreement coefficient is less than 0.001, which is less than the significance level of the test, i.e. 0.05. So, it can be said that the Kappa coefficient for these categories is not zero. It is concluded that non-parametric and parametric methods have no difference in obtaining pure and applied categories. The amount of Kappa coefficient indicates a high agreement both for the classification of two non-parametric and parametric methods and for the pure and applied fields of this database. Also, in comparison of parametric and non-parametric methods of pure and applied fields in statistics based on the MCQ index in the Mathscinet database, the accuracy of these comparisons in pure and applied fields is equal to 79.44% and 97.11%, respectively, and the degree of misclassification 58.6% and 2.89% were obtained, respectively. The results show that the proposed methods to categorize the journals in each database, are more accurate and more efficient, and categorize the journals according to their actual validity.

The parametric method is more accurate than the classification method in the three databases, because the parametric method pays attention to the statistical distribution of the journals ranking index. Therefore, the parametric method, in addition to more accurate classification of journals based on quality, helps researchers to be able to more accurately and efficiently select the journal according to its qualitative category. Also in this paper, an attempt was made to provide a kind of classification for mathematics and statistics journals.

study and analyze the situation of scientific diplomacy in Iran in the last half century and to compare the pattern of cooperation of the authors of articles based on the citation index of Web Science during the years 1975 to 2022.This research is of applied scientometric type. The research population included all joint scientific products of Iran in the international web-based citation database with foreign countries during the years 1975 to 2022. The pattern of joint Iranian scientific productions has been studied and analyzed during this period.International scientific products of Iran during the years 1975-2022 were examined and analyzed in the WOS International Index. The findings show that over the past half century, the United States, Canada, the United Kingdom, Australia, Germany and China have been at the forefront of Iranian scientific diplomacy. Iran ranks 21st in the world in scientific diplomacy in 2017, which in 3021 has reached 30th.The research findings also showed that most of Iran's scientific productions were in the form of scientific papers and then conference papers. Papers presented at international conferences are a clear symbol of scientific diplomacy. Accordingly, 56,190 papers presented at international scientific conferences were indexed on the website of the Science, which accounted for about 8.5% of Iran's scientific production in the last half century (the total number of Iranian scientific production was 676690). The growth trend of papers presented in international scientific conferences in the last ten years showed that the most scientific papers of international conferences in 2015 (3959 papers and 7.04% of the total papers presented), 2014 (3714 papers and 6.6%, respectively). Total articles submitted) and 2017 (3334 articles with 5.6% of total articles) and the lowest number of articles in 2022 (3 articles with 0.005% of total articles), 2021 (631 articles and 1.12% of total articles) And 2020 (1750 papers and 3.11% of all papers submitted) presented at international conferences indexed by WOS.From 2019 to 2022, when the world was infected with the COVID -19 virus and its various strains such as Delta and Omicron, etc., we saw the least international participation in the field of international conferences. This influenced scientific diplomacy, which seems natural

This study aims to investigate the interdisciplinary relationships of biomedical engineering with other scientific domains in WoS during the period 1997 to 2017.

The method of the present study is descriptive survey-analytical with a quantitative and scientometric approach. The study population consisted of 9100 articles related to biomedical engineering indexed in the WOS for 21 years. 955 articles were selected through stratified random sampling.

Scientific production in the field of biomedical engineering from 1997 to 2017 has a growing trend. The tendency to co-authorship with a collaboration coefficient of 0.77 in this field is high. Data visualization showed that "biomedical engineering", "materials science - multidisciplinary", "polymer science", "electrical and electronic engineering" and "tissue and cellular engineering" are the most frequent and effective fields.

Conclustion: 

The process of research and scientific and hot topics in this field and common fields and their impact has led to the emergence of new fields of study in this profession. Since the group collaboration rate of researchers in this field is at a high level, researchers can contribute to the advancement and development of biomedical engineering through wider communication with each other.

“Social Media” has emerged as new phenomenon in the scope of research and academia since 2005. Using Meta-Analysis (Scientometrics Approach) as a research method, the purpose of this study was to review over the past trends of Research & Development (R&D) in the area of “social Media”. The population of this study was all scientific documents indexed in Web of Science (WoS) databases from 1970 until June 2019 with the keyword of “Social Media” as a subject (all together 40,471 documents with “Social Media” as a subject and 15,038 documents with Social Media” in the Titles). To find out the conceptual transformation, all collected documents have been divided into three categories based on their frequency: 1-from 2005 to 2011, 2- from 2012 to 2015 and 3- from 2016-2019. The “theme analysis” of the documents in this study shows that a significant conceptual transformation can be highlight in R&D from 2005 to 2019 in the area of “Social Media”. in addition, even though US, UK, China and other western countries were the first nations who start R&D in the area of “Social Media”, it was noted that especially after 2015, many new and emerging countries like Malaysia, Qatar, Jordan, U.A.E., Pakistan, Kazakhstan and etc. in the developing countries also came to the picture in establishing international R&D networks to also contribute to the body of knowledge in this area.

 Introduction :

Geography has always been based on the three basic elements of human, the environment and the relationship between them and depending on what the concept of man has been in different eras, it has led to the formation of numerous approaches such as classical geography, regional, spatial and phenomenological. However, the introduction of a systematic approach into geography had many implications, including the formation of the human ideal which is called "sustainable development", and led to the participation of different branches of environmental science in sharing and providing solutions for achieving sustainable development. A review of past research shows that Geomorphology has a closer look at the relationship between humans and the environment. It should therefore be examined that what has Geomorphology to offer the global environmental change debate and how might this contribution be framed? To answer this question, the views of scientists must be examined through the process of research related to the relationship between man and the environment during the short life of geomorphological knowledge and this is exactly what was used in this study with the help of CiteSpace software for citation analysis. Using this method, we can examine the relationships between the factors influencing the production of a particular research along with its historical trends in explaining the intellectual structures of knowledge. The purpose of the present study is to use the data available in the Web Of Science database and CiteSpace software to analyze researchers spatially and temporally; Clustering strategic keywords with the help of indicators such as centrality and finally, examining the thoughts of influential researchers in each cluster in order to understand the scientific structure of knowledge in the field of human-environment relationship in Geomorphology 

 Material and Methods:

 In this study, CiteSpace software was used for statistical analysis of scientific citation data. So, in the first step, all the researches between 1970 to 2018 were extracted through web filtering (CiteSpace raw data provider) and after monitoring, a set of 456 articles was obtained. After entering this data into the software, charts of the number of articles and citations, journals and active countries/institutes, burst-detection, country/institute co-citation maps and co-author map were prepared. Then, the present research period was categorized into seven clusters by calculating the centrality of keywords and using the year of production of each word. Each cluster that encompasses a specific time period was analyzed with the help of parameters such as the number of research and citations, the most strategic keywords, the most cited and most famous authors, the external scientific influencers factors, the relationship of other keywords to the strategic word in the tf-idf chart. It was also tried to study the trends of geomorphological knowledge in each of the clusters according to the domestic writers' research and comparing with the results obtained from CiteSpace software.  

Results and Discussion:

 According to co-citation analyzes, the leading Geomorphology journal in terms of number of research and citation indexes among all the journals indexed in the WOS database indicates the importance of geomorphological knowledge in addressing the issue of human-environment communication among the various branches of environmental science. The analysis of the distribution of countries and institutes in relation to the research shows that the results are consistent with the Pareto law. It can also be pointed out that countries' backgrounds influence their ranking as top countries in terms of number of studies although the results show that the research topic is more important for countries. According to the authors' co-citation map, the core of the researchers is made up of authors such as Phillips, Schumm, Goudie and Gregory. The results of comparing the Burst-detection and the In-network citation indicate a low citation among authors with high Burst-detection. Violation of this rule in the case of Schumm shows that in addition to presenting a new idea, he has remained an important citation index throughout the entire period studied. Keyword analysis shows that "Geomorphology, climate change and Holocene" have the highest frequency, "Geomorphology and vegetation" have the highest sustainability and "environmental change, climate change and human impact" have the most Burst-detection. The centrality index also identified the most strategic words that resulted in the clustering of the entire research period into seven clusters to identify the scientific structure of knowledge in the present study.

Conclusion:

 According to information obtained until 2000, most geomorphologists' focus on Geomorphology knowledge was a general trend of environmental science research that was most influenced by global conferences on climate and human environment. The geomorphologists' systematic view is quite evident in order to provide a solution to the issues between the landscape and human impact in the second period between 2000-2002. Co-citation studies from 2002-2003 suggest a new approach to solving problems in human-environment interactions under the heading of combined geo-ecological research in geomorphological knowledge. In the fourth period, between 2003-2005, geomorphologists have used the fluvial Geomorphology-related topics to better illustrate human impacts on the environment. In the next period (2005-2008) was made a rethinking of the geo-archeological studies of ancient times and early humans. Also a common point of most research in this period is the use of river/sedimentary Geomorphology and vegetation data which includes the strategic keywords of the previous period (2005-2003) and the next period (2009-2008) respectively. Because of the use of the sediment keyword and thus a more specialized perspective at environmental protection, the sixth period can be cited as a turning point in determining the extent of geomorphologists' involvement in human-environment research. In the last period, the 'Environmental Change' strategic keyword, remained unchanged for 9 years (unlike all six previous periods in the 17 years ending 2009 with 35 strategic keywords) which shows that geomorphologists have reached an agreement in human and environmental research. And more importantly, it may be the answer to the basic question in the introduction to this study; what has Geomorphology to offer the global environmental change debate and how might this contribution be framed? 

The present investigation intends to compare and review various user interfaces from user standpoint and to ascertain its linkage with user satisfaction. The research incorporated a descriptive survey of University of Tehran graduate student body. Using a targeted sampling، graduate students from the faculties of chemistry and Biology were selected. The instruments used were: A researcher-constructed questionnaire based on Nielsen’s 10 component model; and QUIS user satisfaction questionnaire. Each database UI were evaluated based on five indicators of general features، search features، retrieval features، display features and user-friendliness. Findings indicated that with an average of 3. 88 the Elsevier database had the highest score. Users surveyed believed that the quality of user interface was in better shape than other UI. One should note that this advantage is not indicative of overall database quality and the relatively better interaction on the part of users could be ascribed to their familiarity with the said database and its resource location process. the main purpose of designing and developing a database is to accruing user satisfaction in search and retrieval process. Hence User satisfaction directly connected to user interface.
