Bibliometrix: An Easy Yet Powerful Approach for Quantitative and Qualitative Analyses of Scholarly Literature

Bibliometrics is a field of study that uses quantitative analysis and statistics to describe patterns of publication within a given field or body of literature. By analyzing characteristics of publications such as citations, authorship, keywords, and collaboration networks, bibliometrics helps map the intellectual structure and evolution of scientific disciplines. It provides useful indicators for research evaluation and informs strategic decision making in academia and research organizations.

Over the past few decades, bibliometrics has grown significantly as an important branch of library and information science. The widespread digitization of scholarly literature and availability of large publication databases have enabled comprehensive bibliometric analyses on a scale not possible before. A variety of specialized bibliometric tools and software have been developed to facilitate quantitative and qualitative assessments of research outputs.

One such comprehensive tool for bibliometric analysis is Bibliometrix, an open-source R-based web application. Developed by scientists at the University of Urbino Carlo Bo in Italy, Bibliometrix provides researchers with a complete workflow for conducting bibliometric studies and mapping knowledge domains. It integrates functions for data import, cleaning, analysis, visualization, and reporting into an easy-to-use web interface.

Bibliometrix allows users to import publication records in various formats like BibTeX, RIS, EndNote XML directly from major bibliographic databases including Scopus, Web of Science and Google Scholar. It automatically processes the imported data to extract bibliographic couplings, citations, author keywords and creates networks. The tool supports large datasets with no limit on the number of records or network nodes that can be analyzed (Zupic and Čater, 2015).

Once the data is imported and preprocessed, Bibliometrix offers a variety of bibliometric indicators and analytical functions. It generates statistics on publications, authors, journals, countries/ institutions and their collaborations. Keywords are extracted and analyzed to map the thematic structure and trends. Citation and co-citation networks are constructed to detect the intellectual base and influences. Cluster detection algorithms are employed to identify research fronts and specializations.

For visualization, Bibliometrix integrates VOSviewer software which generates interactive maps based on the network and cluster analyses. Different types of maps can be produced showing journals, authors, keywords, citations and their relationships. These maps provide intuitive representations of the knowledge domain under study and help identify emerging patterns.

In addition to interactive visualizations, Bibliometrix also generates comprehensive bibliometric reports with indicators, statistics and network graphs. The reports summarize key findings from the analyses and present an overall profile of the research field, publication trends and influential publications/authors. They serve as a valuable tool for strategic research assessment and planning.

Researchers have reported that Bibliometrix performs robust bibliometric analyses on large datasets in a short time with reliable results. Its user-friendly interface allows non-experts also to conduct quantitative and qualitative evaluations. The tool has been successfully utilized in diverse domains like health sciences, engineering, social sciences and humanities for mapping research landscapes, benchmarking institutions and informing policymaking (Aria, M., and Cuccurullo, 2017).

In summary, Bibliometrix provides scientists and research administrators with a powerful yet simple to use platform for comprehensive bibliometric studies. By integrating data processing, quantitative analysis, visualization and reporting features, it offers a complete workflow for science mapping and knowledge domain exploration. The tool has significantly enhanced the scope and applications of bibliometrics in research evaluation and strategic decision making.
