graphOnt: An ontology based library for conversion from semantic graphs to JUNG

In this work, we present the software library graphOnt. The purpose of this library is to automate the process of dynamically extracting ldquointerestingrdquo graphs from semantic networks. Instructions on the extraction are fed into the library via an ontological language specification custom built for this application. A set of SPARQL queries are used to define vertices and edges in the constructed graph. Extracted graphs are returned using the JUNG framework, which offers many algorithmic and visualization options. This work allows a set of individuals analyzing the same semantic network to extract and analyze dynamically created graphs using sophisticated, specific algorithmic tools without needing to manually construct classical graphs from the data.
