CiteSpace is a free Java application created by Chaomei Chen that users can download to visualize and analyze trends in scientific literature. The primary source of input data for CiteSpace is the Web of Science, and CiteSpace also provides simple interfaces for obtaining data from PubMed, arXiv, ADS, and NSF Award Abstracts. Search records from Derwent World Patents Index can also be visualized in CiteSpace.
A user guide describes the following steps for visualizing information on CiteSpace:
- Collect Data - The primary source for data is Web of Science, and default input data format is ISI Export Format.
- Create a Project - Consists of two directories: input data files and files generated by CiteSpace for analysis and visualization.
- Adjust Parameters - Change time slicing, node types, term sources, term selection, links, pruning, and visualization options.
- Generate Visualizations - Available visualizations include Cluster View, Time-Zone View, Show Networks by Time Slices, and Show Merged Networks.
- Explore Visualizations
- Generate Clusters - CiteSpace uses a spectral clustering algorithm to decompose a network, and the resultant clusters are mutually exclusive (one item to one cluster).
- Generate Cluster Labels - Labels can come from three sources: title terms, abstract terms, or index terms.
