In co-word analysis, it is assumed that the most frequent words have a greater impact on a subject area compared to the less frequent words. The purpose of the current research is co-word analysis of review articles on the subject of "cloud computing" indexed in the PubMed database in 2009-2022 time period.

The current research is applied in terms of nature which utilized co-word analysis to analyze the data. The statistical population included 169 review articles on the topic of "cloud computing" indexed in the PubMed database in 2009 to 2022 period. The total of 57 articles lacked keywords which were excluded from the study. The required data was retrieved from the mentioned database by entering the word "cloud computing" in the subject field which were subsequently added to the Excel software. Voyant Tools software was used for co-word analysis.

Based on the maps obtained from co-word analysis, keywords fog computing, data computing, cloud database, Internet of Things, cloud data, cloud challenge, cloud technology, cloud systems, health systems and cloud overlapped the most with the term cloud computing. Drawing maps of co-word at different time periods under investigation illustrates changes and stability in the concepts and words related to the field of informatics. New concepts emerged as a recombination of existing words interacting with developments and new technologies.

The most frequent word in cloud computing review articles in all the texts indexed in PubMed among the words cloud computing, data computing, cloud database, Internet of Things, cloud data, cloud challenge, cloud technology, cloud systems , has been health and cloud systems in which  the terms "data computing" and "fog computing" overlaped the most with cloud computing.

The purpose of organic food production is to keep human health and impose minimum damage to the environment. Regarding the need for organic food production, the aim of the current research is to analyze and investigate the scientific outputs of the organic food field, which are indexed in the Web of Science (WoS).

The present study is descriptive which was carried out, applying a scientific approach. The scientific productions in the field of organic food were extracted from WoS database and all subject areas related to organic food were investigated. The extracted data were analyzed through Bibliometrix and its graphical user interface, Biblioshiny. Bibliometrics package as well as SPSS and Excel were used.

The findings of the research state that strategic diagram is divided into four regions based on the degree of development (density index) and the degree of connection (centrality index). The first quarter represents the central and developmental topics which include organic food consumption. The second quarter of the graph depicts the special topics of this field, which include antioxidant activity, biological density factor, Listeria monocytogenes (the name of a pathogenic bacterium) and Escherichia coli (the name of a bacterium). The topics in the second area have high density and low centrality. The third quarter covers topics that have low density and centrality. These topics are emerging or declining which includes the issue of agricultural networks is the quarter. The fourth quarter represents basic topics which has low density but high centrality. This area includes food management, health quality and nutritional quality of vegetables.

The results state that researches in the field of organic food have focused on topics such as attitudes, consumption behaviors and willingness to buy organic food, as well as the quality of organic products.

The present research aims to draw and analyze the scientific collaboration network in the field of cultural heritage protection based on the data retrieved from the AATA database from 1800 to 2020.

This is a descriptive and applied research which was conducted with a scientometric approach. The research community includes all articles indexed in the AATA database from 1800 to 2020. Articles were reviewed in terms of micro and macro network parameters. Vosviewer, Microsoft Excel, Ucinet and Ravar PreMap were used to analyze the research data.

The mean growth rate of articles is 14.12% and the doubling time of studies is 4.96 years. The mean growth rate of authors is 16.97% and the doubling time of researchers is 4.12 years. Based on macro network parameters, network density is 0.001, network cohesion is 0.186 and network diameter is 24. Single-author researches are decreasing and the collaboration of authors in researches is increasing. Collaboration index, collaboration degree and collaboration coefficient have increased and reached 3.93, 0.79 and 0.57, respectively, in 2020.

Examining the macro parameters of the co-authorship network in this field shows the low cohesion of the authorship network and according to the values ​​of network diameter and the average distance, the distribution of information in this network is unfavorable, and chemistry researchers with high betweenness centrality have more influence than other researchers in the field of cultural heritage protection.

Word co-occurrence is a method for studying the intellectual structure of knowledge in various subjects. Experts in science assessment studies use it to map the relationship between concepts and ideas in basic and social sciences. The main goal of the present research is to draw the intellectual structure of library and information science books based on book citation index.

The present study is an applied research based on word co-occurrence and social network analysis. The statistical population of this research includes 16499 books indexed in the field of librarianship and information in Web of Science. BibExcel, UCINET, and NetDraw were used in this study to homogenize and analyze the data.

The most frequent co-word pairs were "ISO 9001-Quality Management Systems with a frequency of 12" and "Librarian-Web 2 with a frequency of 10." Cluster analysis showed six clusters of "scientific communication and digital publications," "library management and social participation," "information policy and technology management," "education and leadership in information services," "management and governance," and "digital network and development of the library and information science profession" in this study. Also, the keywords participation, library and information literacy had the highest degree centrality with 68, 55 and 47. The keywords research case, information and politics had the highest close centrality with 254, 253 and 252. Finally, the keywords participation, information literacy and library had the highest centrality index with 826/582, 518/835 and 512/802. The findings also indicate that about 16% of the books published in this subject area aligned with the fourth goal of sustainable development, quality education.

The keywords "participation," "library," "information literacy," "university library," and "librarian" play a significant and decisive role in social network of librarianship and information books in drawing the map of science.

Engaging in research and familiarizing oneself with the research field are integral aspects of student development programs, particularly at postgraduate level. This study aims to analyze and map the co-authorship network within publications produced by the student research committee of Iran's Ministry of Health and Medical Education.

This is an applied research that utilizes scientometric techniques. The research community includes 2178 documents with the organizational affiliation of the Student Research Committee of Medical Sciences Universities of the Ministry of Health and Medical Education, which were retrieved from the Scopus database from 1985 to 2023. After data cleaning in Excel software and data homogenization, the data were transferred to BibExcel for frequency analysis. Subsequently, UCINET software was employed to calculate the correlation and centrality matrix. Furthermore, VosViewer software was used to visualize the data through network maps.

An analysis of student research committee publications revealed 900 co-authored articles. Salari and Mohammadi exhibited the highest co-authorship frequency, with 10 publications. The findings showed that 38 countries participated in the scientific productions of the student research committee. America and England have cooperated the most with authors of student research committees with 58 and 14 scientific publications, respectively. Yousefi, Nouri, and Mohammadi emerged as the most prolific research committee authors. Sadeghi got the highest score in terms of centrality index and Karimi got the highest score in terms of closeness and intermediateness index. Furthermore, the five-author co-authorship pattern represented the most prevalent format (19.04%), with the single-author format accounting for less than 1% of publications.

In studies by student research committee, the five-author co-authorship pattern has been the dominant pattern among the scientific documents of the student research committees, which indicates proper scientific cooperation among students.

One of the factors that affects the aesthetics of a website and attracts more users in the web environment is "visual complexity". The present research analyzed the correlation and regression between the SEO score and the level of visual complexity of the library websites of the top Iranian and international universities.

A comparative evaluation approach was adopted in this research. 41 library websites of top international universities (based on University Ranking 2023) and 41 library websites of top Iranian universities (based on ISC database 2021) were analyzed and compared. AIOSEO Analysis tool and Athec Python library were used for data extraction. SPSS was used for data analysis. Figures were generated using Excel.

There was no significant correlation and regression between SEO and visual complexity on library websites of top international universities (p=0.125). However, on library websites of top Iranian universities, there was a weak correlation (p=0.045; Pearson correlation coefficient=0.362) and a significant regression (p=0.045). According to the Mann-Whitney U test, a significant difference was seen between the two groups of library websites of top Iranian and international universities from the standpoint of visual complexity (p=0.019).

While top international academic libraries can rely on their strong branding, Iranian university libraries need to focus on both aesthetics and SEO to improve their visibility. Thus, using the experiences and knowledge of expert librarians in the fields of "SEO" and "aesthetics" is recommended.

This study provides a comprehensive scientometric analysis of research literature in the field of water resources management in Iran, aiming to identify trends, patterns, and the impact of research in this domain between the years 2006 to 2023.

To map the scientific landscape of this field, all published articles by Iranian authors in international journals (662 documents) were collected from the Scopus database within the time frame 2006-2023. Scientometric techniques such as co-authorship networks and co-occurrence maps of keywords were utilized for data analysis. Key indices such as h-index, citation counts, and journal impact factors were calculated to assess the visibility and impact of Iranian research in water resources management. Statistical analyses were conducted using R software and VOSviewer.

The findings revealed that the growth rate of Iranian papers in water resource management was 24.05%. In addition to quantity, the quality and citation rate of the articles have also increased over the years. A significant relationship (r=0.584) was observed between the number of documents and the number of citations of the authors. Furthermore, with an increase in the number of authors for each article, the number of citations for that article also increased significantly (r=0.180). The analysis of the scientific map of the studies revealed the identification of a pattern of six clusters, and climate change and water supply sustainability as the first cluster received the most emphasis in studies by Iranian authors.

Climate change and water supply sustainability are among the most important areas that have received attention from Iranian researchers in recent years, which seems reasonable given the trend of climate change and frequent droughts in the country. There has been a significant increase in the number of citations as the number of documents authored by researchers has risen.

Bibliographic analysis by describing the status of publications and identifying emerging issues plays an important role in research evaluation. The aim of the present research is to draw the scientific collaboration networks of researchers, organizations, and scientific centers and the co-occurrence of scientific terms in articles related to the local history of Azerbaijan in Iranian Scientific Journals from 2011 to 2021.
This descriptive-analytical research is of bibliometric type. The samples include 111 scientific articles about the local history of Azerbaijan from 2011 to 2021, published in the country's scientific publications. The drawing of the scientific collaboration network of researchers, organizations, and scientific centers, as well as co-occurrence network analysis of scientific terms were done using VOSviewer.
The scientific centers of the Northwest had the most participation in publishing articles. There is a significant relationship between the scientific rank of researchers and their scientific participation (P-value=0.021). In terms of historical periods, the Qajar period and, in terms of subject matter, political history attracted the most attention from researchers. Moreover, the universities of Tabriz, Azerbaijan Shahid Madani, and the Institute for Humanities and Cultural Studies produced the most articles. The words "Azerbaijan" and "Tabriz" had the highest frequency of repetitions in the articles on the history of Azerbaijan. In terms of the co-occurrence of terms, the focus has been mostly on the Qajar period and especially the Nasrid period.
The trend of publishing articles about the local history of Azerbaijan has quadrupled in the studied period. Despite this upward trend, some historical periods and important topics have not been given much attention due to the lack of resources and certain challenges. It seems that the reason why professors and researchers paid more attention to the subject, in addition to local tendencies, was a better understanding of regional issues.
