Welcome to CiteSpace! CiteSpace visualizes the evolution of a network across a number of time sliced intervals.


CiteSpace is a Java program for co-citation analysis, especially for visualizing co-citation networks.

The underlying techniques implemented in CiteSpace are explained in a PNAS paper (see Publication section):


Currently, it takes citation data in the ISI Export format and generates node-and-link drawings of co-citation networks. A typical way to use it is to slice a time interval into smaller segments and study how co-citation networks over individual time slices are patched together. The PNAS paper illustrates how to find intellectual turning points by visually searching for pivot points in such patched co-citation networks.


Please get in touch with me via email if you have questions about its current status and availability.
