VizCMAP is a analysis tool for comparing CMaps between pre-search and post-search.
Once you transcribe concept maps into GraphViz? (dot) format, this tool allows you to you can easily check what was changed between two concept maps, as follows.
The nodes encircled with double lines represent the common nodes. The links drawn with double lines with large arrows represent the common links. The nodes encircled by a dashed line represent the lost nodes, and the links drawn with a dashed line are the lost links. The nodes encircled by a solid line represent the new nodes, and the links drawn with a solid line are the new links. Please refer to the following paper for an overview of analysis methods on pre- and post-search concept maps:
