Introduction/Aim. Essential Science Indicators (ESI) Highly Cited Papers (HCPs) refer to the most influential scientific articles and breakthrough research within a research field in the past decade. This study aimed to identify the characteristics of ESI HCPs in the subject category Dentistry, Oral Surgery and Medicine, to recognize authors, institutions and countries of origin, and determine research trends that attracted the most scientific interest in dentistry. Methods. A descriptive analysis of bibliographic data, network extraction and visualization were completed. Furthermore, analyzed ESI HCPs were classified according to a field of interest, main research domain, type of study, and level of evidence. Results. The set of 185 dental HCPs was published in 42 journals from 2010 to 2020, with an average number of 211.7 citations per paper. Nearly half of HCPs were issued by the Journal of Dental Research, Dental Materials, and Journal of Clinical Periodontology. There were 765 authors affiliated with 351 institutions from 42 countries. The most productive institutions were the University of Hong Kong, the University of Michigan, and the University of Bern. The USA contributed with the highest number of publications, followed by China, and the United Kingdom. Dental Materials, Dental Implantology, Periodontology, and Oral and Maxillofacial Surgery represented areas of significant interest within this subject category. The highest proportion of HCPs were narrative and systematic reviews, expert opinions, consensus reports, and in vitro /lab studies. Conclusion. Results obtained from this study can provide valuable information for researchers to better identify present and future hotspots in dental research.

Представлен обзор мер государственной политики, направленных на развитие технологий искусственного интеллекта(ИИ) в мире и в России. С целью оценить конкурентоспособность отечественных разработок, созданных для использования техно-логий ИИ в медицине и здравоохранении, выполнен наукометрический и патентный анализ направления за период 2010–2019 гг.На основе анализа фронтов исследований по методологии Essential science indicators выявлены наиболее перспективные на се-годняшний день исследовательские стратегии. Показано, что на глобальном публикационном ландшафте Россия занимает 27-уюпозицию в мире по числу публикаций, посвященных применению ИИ в здравоохранении: на долю российских исследователей при-ходится менее 1% публикаций, проиндексированных в Web of science. Для вхождения в топ 5 стран по публикационной активности в этом тематическом кластере России необходимо увеличить число публикаций более, чем в 6 раз. Из 16 компаний, аффилиации которых указаны в публикациях с участием российских авторов, 13 являются зарубежными. В целом, только 14% публикаций в тематической категории «Сomputer science, artificial intelligence», выполнены в коллаборации с индустриальным сектором. На ландшафте, сформированном патентными документами, защищающими технические решения в области ИИ в медицине, Россия занимает позиции, не подтверждающие ее намерения вступить в борьбу за перспективные рынки товаров и услуг, созданные на базе этих технологий. В области разработок ИИ медицинского назначения число патентов РФ, выданных нерезидентам страны, существенно превосходит число отечественных правообладателей. Обнаружены всего 12 патентов российских разработчиков технологий ИИ для здравоохранения, выданные зарубежными патентными ведомствами.

Highly cited papers in the Essential Science Indicators database refer to papers with citations in the top 1% of all papers in a research field, and they are considered to be symbols of scientific excellence and top performance of the past ten years. This study provided an informetric analysis of 7791 highly cited papers in the environmental sciences category during 2009–2019. Informetric indicators and visualization tools were applied to evaluate and present the performances of journals, countries/territories, institutions, top cited papers, and research hotspots. The results showed that the cumulative number of publications has increased exponentially, suggesting strong development of the environmental sciences category. There were 211 journals publishing highly cited papers, with Energy & Environmental Science as the leading journal. The USA ranked first with the highest number of publications and occupied the core position in the collaboration network, while Mainland China took the first place in independent research output. Review articles have an obvious advantage in terms of achieving high citations. “Adsorption”, “climate change”, and “heavy metal” were the most frequent keywords, with “microplastic” rising rapidly as a new research frontier in recent years. Five research hotspots were visualized from highly cited papers via cluster analysis.
