Global maps of science can be used as a reference system to chart career trajectories, the location of emerging research frontiers, or the expertise profiles of institutes or nations. This paper details data preparation, analysis, and layout performed when designing and subsequently updating the UCSD map of science and classification system. The original classification and map use 7.2 million p...

BACKGROUND Local and regional scientific journals are important factors in bridging gaps in health knowledge translation in low-and middle-income countries. We assessed indexing, citations and publishing standards of journals from the Eastern Mediterranean region. METHODS For journals from 22 countries in the collection of the Index Medicus for the Eastern Mediterranean Region (IMEMR), we ana...

This study aimed at quantitatively and qualitatively evaluating Iranian researchers' scientific output in the field of dentistry and determining their contribution in each of dentistry subfields and branches. METHODS This research was a scientometric study that applied quantit...

Introduction: There are no studies that specifically compare research output of Palearctic and Neotropical mammalogy; such comparison would be useful for informed decisions in conservation management. Objective: To the scientific documents citations about mammals over half a century. Methods: We compared 50 years (1970-2019) on 60 medium large-sized (heavier than 1 kg) mammal species, Scopus We...

Introduction: Traditional citation analysis has been greatly criticized because the process of citation accumulation requires considerable time after publication. So, the term “altmetrics” was proposed in 2010 to measure the scientific and social impact of a paper.We performed a search for certain nuclear medicine topics using the altmetrics approach to report the correlation b...

To enable scientific development, research must be communicated. Scholarly communication has evolved over the years, but not way how researchers have to justify their output. This scoping review aims describe situation of main search engines Web Science and Scopus, which are based on own journal collections, others citation web searches such as Google Scholar, Dimensions, The Lens. A bibliograp...

In the last decade, Particle Swarm Optimization (PSO) has grown in popularity as one important method for optimization, compared to recent Differential Evolution (DE) and Harmony Search (HS). In this paper a bibliometric study is presented, carried out on the PSO research literature from 2000 to 2010. The Thomson Reuters Web of Science (WoS) was used to collect publication records and analyzed ...
