PQViz is a tool that has come out of our Jambalaya and CogZ research. The tool is available as a Protégé plugin and it provides a simple query interface for Protégé ontologies. Results are visualized as structural neighborhoods based on the ontology’s relationships, which can be interactively explored. This tool is similar to Jambalaya’s query tool interface, but uses different strategies for laying out and labeling nodes.

PQViz was developed with support from the National Center for Biomedical Ontology.
