Science mapping networks
Keyword co-occurrence, co-citation, bibliographic coupling and co-authorship, with network, overlay and density views, Louvain clusters and centrality measures.
Thematic map and evolution
Motor, niche, emerging and basic themes from Callon’s centrality and density, and a Sankey diagram of how themes evolve across periods.
Roots and research fronts
Historiograph, reference publication year spectroscopy, trend topics, Kleinberg burst detection, factorial analysis and clustering by coupling.
Exports that save days
Word report with figures and APA tables, Excel workbook, HTML, SVG and 300-dpi PNG, plus VOSviewer, Pajek, GraphML and Gephi files and a PRISMA diagram.
How it works
From database export to a finished results section
01
Export your records
Save your search results from Scopus, Web of Science, PubMed or another database. Step-by-step export guide.
02
Import, merge, clean
Drop the files in. Merge synonyms, remove generic keywords, and filter by year, document type or language.
03
Explore 40 analyses
Every page has a figure, the full table and a short explanation of how to read it, with options to tune.
04
Export and cite
Download a Word report or single figures and tables, copy the methods paragraph, and cite the software.
Science mapping
Networks you can read, and export
Choose the items (keywords, references, authors, sources, countries), the normalisation (association strength, Salton, Jaccard) and the clustering resolution. Switch between the network, overlay-by-year and density views, and hover any node for its numbers.
- Louvain clustering with a resolution setting
- Degree, betweenness, closeness and PageRank for every node
- Overlay by average publication year or citations
- Export to VOSviewer, Pajek, GraphML and Gephi
Conceptual structure
Themes, their development and their history
The thematic map places each theme by how central and how developed it is. Thematic evolution links the themes of successive periods. Factorial analysis and the topic dendrogram show how keywords group into topics.
Motor themesHigh centrality and density: well developed and central to the field
Niche themesWell developed but weakly connected to the rest
Emerging or decliningWeak on both dimensions
Basic themesCentral but not yet well developed
Data you can trust
Merge databases without double counting
Web of Science and Scopus overlap heavily. Bibliometrics Studio matches duplicates by DOI, then by normalised title and year, keeps the most complete version of each record, and shows exactly how many were removed. A completeness table tells you which fields each analysis can rely on.

FAQ
Frequently asked questions
Is Bibliometrics Studio really free?
Yes. Every analysis and export is free, with no account, no trial and no limit on the number of records. It runs entirely in your web browser.
Are my exported records uploaded anywhere?
No. Your Scopus, Web of Science, PubMed or other files are read and analysed inside your browser tab. Nothing is sent to our server.
Which databases and file formats are supported?
Scopus (CSV, BibTeX, RIS), Web of Science (plain text, tab-delimited, BibTeX, Excel), PubMed (MEDLINE/PubMed format and CSV), Dimensions (CSV or Excel), Lens.org (CSV), OpenAlex (CSV), and RIS or BibTeX files from Google Scholar (via Publish or Perish), Zotero, Mendeley, EndNote, IEEE Xplore, EBSCO or ProQuest. Any CSV with a Title column also works.
Can I combine Scopus and Web of Science data?
Yes. Drop all your export files at once. Records are merged, and duplicates are removed by matching DOIs and normalised titles with publication years. The most complete version of each record is kept, and the number of duplicates removed is reported for your PRISMA diagram.
Is this a free alternative to biblioshiny and VOSviewer?
It covers the analyses researchers typically report from biblioshiny (the bibliometrix web interface) and VOSviewer: main information, sources, authors and countries, Bradford’s and Lotka’s laws, h-index, keyword co-occurrence, thematic maps and evolution, factorial analysis, co-citation, coupling, collaboration networks and historiographs, plus CiteSpace-style burst detection, all in the browser without installing R or Java. It is an independent implementation and is not affiliated with those projects.
What is the difference between co-citation and bibliographic coupling?
Two references are co-cited when a later document cites both of them, so co-citation maps the intellectual base a field builds on. Two documents are bibliographically coupled when they cite the same references, so coupling groups current research into fronts. Bibliometrics Studio runs both, for references, authors, sources and countries.
How is the thematic map calculated?
Keywords are grouped into themes by clustering their co-occurrence network (Louvain algorithm on association-strength weights). Each theme is placed by Callon’s centrality, the strength of its links to other themes, and density, the strength of the links inside it (Callon et al., 1991; Cobo et al., 2011). The quadrants show motor, niche, emerging or declining, and basic themes.
Can I export networks to VOSviewer, Gephi or Pajek?
Yes. Every network can be downloaded as VOSviewer map and network files, a Pajek .net file, GraphML, or Gephi node and edge CSVs. You can also export the merged data set in Web of Science format to open in VOSviewer, CiteSpace or bibliometrix.
Does it make a PRISMA flow diagram?
Yes. The identification counts (records per database and duplicates removed) are filled in from your imports, and you enter the screening numbers. The PRISMA 2020 diagram can be saved as SVG or 300-dpi PNG.
Which exports are available?
Every table as CSV, Excel or copy-paste; every figure as SVG or 300-dpi PNG; a complete Word report with figures, APA-style tables, a methods paragraph and method references; an Excel workbook with all tables; an HTML report; and a ZIP with all figures and tables.
