What is VOSviewer
VOSviewer is a software tool for building and visualizing bibliometric networks. For example, these networks may include journals, researchers, or individual publications, and they may be constructed based on citations, bibliographic couplings, co-citations, or co-authorship relationships. VOSviewer also provides text mining capabilities that can be used to build and visualize co-occurrence networks of important terms extracted from scientific literature.
Special feature
data
- Web of Science, Scopus, Dimensions, Lens, and PubMed. Co-authorship, citation-based, and co-occurrence networks can be created from data downloaded from Web of Science, Scopus, Dimensions, and Lens. Co-authorship networks and co-occurrence networks can also be created based on PubMed data.
- Crossref, Europe PMC and OpenAlex. Networks can also be created from data retrieved through the APIs of Crossref, Europe PMC and OpenAlex. These APIs can be queried interactively in VOSviewer.
- Semantic Scholar, OpenCitations and WikiData. For a given set of DOIs, networks can also be created from data retrieved through the APIs of Semantic Scholar, OpenCitations, and WikiData.
Visualization
- Zoom and scroll. Visualizations of bibliometric networks can be explored in detail using zoom and scroll functions similar to Google Maps. Smart labeling algorithm prevents labels from overlapping each other.
- Density and overlay visualization. Density visualization provides a quick overview of the main areas in the bibliometric network. For example, overlay visualizations can be used to show development over time.
- screenshot. Screenshots of bibliometric network visualizations can be created in high resolution and
