Bibliometric analysis is a systematic study carried out on scientific literature for the identification of patterns, trends, and impact within a certain field. Major steps include data collection from relevant databases, data cleaning and refining, and subjecting data to various bibliometric methods—an ensuing step in the generation of meaningful information. Bibliometric analysis is an increasingly popular and thorough technique for examining and assessing massive amounts of scientific data, which is being used more and more in research. This entry thoroughly introduces bibliometric methodology, emphasizing its numerous methodologies. It also provides a set of reliable, step-by-step instructions for confidently performing bibliometric analysis. Furthermore, we investigate the suitable use of bibliometric analysis as an alternative to systematic literature reviews. This entry aims to be a useful tool for learning about the methods and approaches that may be used to perform research studies that use bibliometric analysis, particularly in the fields of academic study.
Bibliometrics has become a trend in academic research in recent years
[1][2][3][4][5]. However, many young colleagues still lack the skills to conduct a start-to-end bibliometric analysis. Conversely, bibliometrics in research is not just a passing trend. First, the term bibliometrics was introduced in the nineteen thirties by the Belgian documentalist Otlet
[6] and was re-invented and made popular by Pritchard in 1969
[7]. In that same year, Nalimov proposed the term scientometrics
[8][9]. Although in those years there were some differences between the two fields, nowadays both terms, bibliometrics and scientometrics, are synonyms
[7][9][10][11][12][13].
Bibliometrics reflects its applicability in handling vast amounts of scientific data and its significant contribution to research impact. Numerous variables, including the development, accessibility, and availability of bibliometric tools like R and VOSviewer and scientific databases like Google Scholar, Scopus, and Web of Science, are responsible for this popularity. The cross-disciplinary influence of the bibliometric methodology from data science to operational research has also played a significant role in its widespread adoption
[14].
Academics employ bibliometric analysis for many other purposes, including uncovering emerging trends in article and journal performance, collaboration patterns, and research constituents and exploring the intellectual construction of a given domain within the existing literature
[15][16][17][18]. The data central to bibliometric analysis is often extensive, for instance, hundreds, if not thousands of pieces, and objective, like the number of citations and publications, occurrences of keywords, and topics. At the same time, its meanings often rely on subjective (for instance, thematic analysis) and objective (for example, performance analysis) evaluations derived via well-informed methods and processes. Through rigorous efforts to make sense of vast unstructured data, bibliometrics, or similarly, scientometrics, helps map and understand cumulative scientific knowledge and evolutionary subtleties of well-established domains. Thus, well-conducted bibliometric research may provide strong groundwork in all fields.
Although bibliometric analysis has many advantages, it is still a relatively new tool in research, and its full potential remains untapped. The results from bibliometric studies provide a fragmented knowledge of an area by relying on a small collection of data and approaches
[16][19][20]. Notably, academics looking for a thorough yet readable resource on the approach and its application have a major hurdle as there is no authorized reference for bibliometric analysis. Although there are reputable manuals for systematic literature reviews
[21][22], they fall short in their coverage of the bibliometric analysis technique.
This entry aims to accomplish two things: first, present a thorough review of bibliometric techniques, and second, present the main steps and instructions for carrying out a bibliometric analysis. This entry introduces bibliometric analysis for academics across all fields, including its principles, methods, processes, supporting details, and explanations. This entry makes significant contributions, as seen in Table 1 below.
