Concepts of Neighbours – Discovering clusters of similar nodes in RDF graphs
An Apache Jena extension that, given an RDF model and an RDF node, returns a set of “concepts of neighbours”. Each concept is composed of an extension and an intension. The extension is a set of similar nodes, and the intension is a node description (a graph pattern) that represents what the similar nodes have in common with the given node. The size of the extension can serve as a distance measure, and the size of the intension can serve as a similarity measure.
A graphical user interface is also available to experiment with concepts of neighbours. Alternatively, a A||Go web service is available to compute concepts of neighbours without bothering about any setup.
