BACKGROUND: The present study was conducted to investigate the scientific contributions of Iranians in the field of cardiovascular research, as indexed in the Scopus database, using bibliometric and altmetric methods. METHODS: This applied study was conducted with a scientometric approach, utilizing bibliometric and altmetric indicators. The research population consisted of the scientific works of Iranian researchers in the field of cardiovascular diseases, indexed in the Scopus database over a period of 47 years. For bibliometric analysis and the generation of co-citation, co-occurrence, and co-authorship maps, the authors employed VOS Viewer software and the bibliometrix package in the R programming language. In the final stage, articles mentioned on social media were analyzed and evaluated using an altmetric approach. RESULTS: The results indicated that the commencement point for the publication of documents was 1975, and there has been a steep increase in recent years. Moreover, the documents were primarily research articles out of 6853 retrieved documents, and a limited number of documents were single-authored. Other findings also revealed the co-authorship map of authors and the co-occurrence of words, highly cited authors and institutions, and highly frequent keywords, signifying the scientific collaboration of Iranian researchers with the United States and England. Altmetric analysis also demonstrated that 43.41% of documents were shared at least once on social media and had an Altmetric Attention score. Furthermore, the analysis of altmetric indices showed that Mendeley, Twitter, and News had the highest share of document mentions on social media, respectively. CONCLUSION: The findings of the study can offer valuable information to researchers, managers, and policy makers to become aware of the current state of research in the field of cardiovascular diseases and implement the necessary policies to inform society and enhance public health status. © 2024, Isfahan University of Medical Sciences(IUMS).

The presence of diverse research in the field of telemedicine necessitates the need to analyze the topics of these studies to have a clear and comprehensive vision of this domain. The present study was conducted with the aim of topic modeling the published articles in the field of telemedicine using the PubMed database. This study employed a descriptive approach using LDA and TF-IDF as text mining techniques. Articles in the field of telemedicine were extracted from the PubMed database using the search formula “Telemedicine”[Majr] without any time limitations. A total of 37,181 records were retrieved. After data cleansing, the abstracts of 31,144 articles were analyzed, and topic modeling was performed. The topic modeling of telemedicine resulted in the identification of eight topical clusters, including e-health, interventions, primary care, remote monitoring, COVID-19, telehealth, cardiovascular disease, and research. The highest publication trend was observed for the COVID-19 topic, followed by primary care. Findings demonstrates the satisfactory performance of the LDA algorithm in topic classification in the field of telemedicine. Also, the results provide a better foundation for developing policies and research programs, as well as increasing awareness and utilization of emphasized topics. Modeling the topics of global telemedicine articles and comparing different algorithms with the current one is recommended for future research. Further studies in this field can lead to improved effectiveness, quality, and accuracy of telemedicine services. © (2024), (International Hellenic University School of Science and Technology).

With the increasing development of information and scientific databases, scientific collaboration has expanded in health sciences. This study aims to prioritize the criteria that affect finding potential author matches in bioinformatics using fuzzy Multiple Criteria Decision Making (MCDM) methods such as Analytical Hierarchy Process (AHP), Fuzzy Delphi Method (FDM), and Triangular Fuzzy Numbers (TFN). To answer the research questions, a mix of documentary analysis and fuzzy methods is utilized. The documentary analysis stage involves collecting relevant documents and resources using the purposive sampling approach and ranking the effective criteria. The subsequent step involves experts determining the priorities of the effective criteria using pairwise comparisons and the Delphi questionnaire. The final weights are obtained based on the research purpose. The study shows that 79 criteria related to the research purpose can be grouped into three general categories: behavioral, topological, and content-based criteria. The most effective criteria in finding and recommending a potential author match are “journal titles”, “citations”, “paper titles”, “affiliations”, “keywords”, and “abstracts”. Among these criteria, citation and paper titles have a higher priority compared to others. The results indicate that content-based criteria have the most significant impact on finding potential author matches in static scholar networks and networks with text information. Furthermore, among the content-based criteria, the number of publications in common specialized journals and the number of common citations are the most sought-after criteria for finding a potential author match with the highest similarity. © 2023 The Authors

Purpose: The COVID-19 pandemic has indisputably impacted every aspect of human life, and a host of studies have investigated its different aspects. This paper models the contents of Persian literature on COVID-19. Method: This is a descriptive-exploratory study in which 815 articles were collected from the Magiran database. The articles were published before March 2022. The abstracts and titles were used in the modeling. The modeling was performed by combining the latent Dirichlet allocation (LDA) algorithm with ParsBERT. Findings: Topic modeling indicated ten major topics, including medicine, psychology, humanities, politics, management, biology, economics, culture, engineering, and religion. The articles under the category of medicine had the largest cluster (42.3%), while engineering and religion had the smallest clusters (1.1% each). Conclusion: The found topics in the created clusters have structural relationships. The COVID-19 effect on physical and mental health (medical and psychological topics) is the most crucial factor. These clusters provide evidence that COVID-19 affects all facets of human society at three levels: the individual, family, and society. Aside from the ten critical clusters in the humanities field, the utmost disorder is related to teaching and learning. For the first time, this research has presented a model of scientific communication in the field of COVID-19 based on the data collected from a Persian database – Magiran. © 2022 The Authors

Health communication is a new field focusing on the “powerful role” of human and media communication in health care services and health promotion. This study intends to explore the intellectual structure of knowledge in health communication literature using the co-word analysis technique. The applied descriptive-analytical method was used in this study to analyze the literature content with a hierarchical clustering approach. For data collection, the descriptors of the keyword “Health Communication” were searched in the medical subject heading (MeSH) in the PubMed database on November 18, 2021, for the period of 1959–2021. Data analysis and clustering were performed using SPSS software (version 20), RavarPremap software, Excell, Ucinet and VosViewer software. Data analysis indicates that scientific articles on communication health have experienced ascending growth pattern. Moreover, the findings on hierarchical clustering led to the formation of six subject clusters with the predominant subjects of “ COVID-19 Pandemic, Health Education & Vaccine Hesitancy.” The present study revealed a structural relationship among subject concepts in the clusters created with common features within each group. This study provided valuable insights into scientific communication patterns in health communication research produced in the PubMed database. © 2022 The Authors

Finding the most suitable co-author is one of the most important ways to conduct effective research in scientific fields. Data science has contributed to achieving this possibility significantly. The present study aims at designing a mathematical model of co-author recommender system in bioinformatics using graph mining techniques and big data applications. The present study employed an applied-developmental research method and a mixed-methods research design. The research population consisted of all scientific products in bioinformatics in the PubMed database. To achieve the research objectives, the most appropriate effective features in choosing a co-author were selected, prioritized, and weighted by experts. Then, they were weighted using graph mining techniques and big data applications. Finally, the mathematical co-author recommender system model in bioinformatics was presented. Data analysis instruments included Expert Choice, Excel, Spark, Scala and Python programming languages in a big data server. The research was conducted in four steps: (1) identifying and prioritizing the criteria effective in choosing a co-author using AHP; (2) determining the correlation degree of articles based on the criteria obtained from step 1 using algorithms and big data applications; (3) developing a mathematical co-author recommender system model; and (4) evaluating the developed mathematical model. Findings showed that the journal titles and citations criteria have the highest weight while the abstract has the lowest weight in the mathematical co-author recommender system model. The accuracy of the proposed model was 72.26. It was concluded that using content-based features and expert opinions have high potentials in recommending the most appropriate co-authors. It is expected that the proposed co-author recommender system model can provide appropriate recommendations for choosing co-authors on various fields in different contexts of scientific information. The most important innovation of this model is the use of a combination of expert opinions and systemic weights, which can accelerate the finding of co-authors and consequently saving time and achieving a greater quality of scientific products. © 2021, The Author(s).

Nowadays, scientific collaboration has dramatically increased due to web-based technologies, advanced communication systems, and information and scientific databases. The present study aims to provide a predictive model for author collaborations in bioinformatics research output using graph mining techniques and big data applications. The study is applied-developmental research adopting a mixed-method approach, i.e., a mix of quantitative and qualitative measures. The research population consisted of all bioinformatics research documents indexed in PubMed (n=699160). The correlations of bioinformatics articles were examined in terms of weight and strength based on article sections including title, abstract, keywords, journal title, and author affiliation using graph mining techniques and big data applications. Eventually, the prediction model of author collaboration in bioinformatics research was developed using the abovementioned tools and expert-assigned weights. The calculations and data analysis were carried out using Expert Choice, Excel, Spark, and Scala, and Python programming languages in a big data server. Accordingly, the research was conducted in three phases: 1) identifying and weighting the factors contributing to authors' similarity measurement; 2) implementing co-authorship prediction model; and 3) integrating the first and second phases (i.e., integrating the weights obtained in the previous phases). The results showed that journal title, citation, article title, author affiliation, keywords, and abstract scored 0.374, 0.374, 0.091, 0.075, 0.055, and 0.031. Moreover, the journal title achieved the highest score in the model for the co-author recommender system. As the data in bibliometric information networks is static, it was proved remarkably effective to use content-based features for similarity measures. So that the recommender system can offer the most suitable collaboration suggestions. It is expected that the model works efficiently in other databases and provides suitable recommendations for author collaborations in other subject areas. By integrating expert opinion and systemic weights, the model can help alleviate the current information overload and facilitate collaborator lookup by authors. © 2021, International Journal of Information Science and Management, All Rights Reserved.
