Conceptual KNN – Discovering clusters of similar nodes in RDF graphs
A Java library based on Apache Jena for computing the concepts of neighbours of a tuple of nodes. Each concept is composed of an extension and an intension. The extension is a set of similar tuples, and the intension is a tuple description (a graph pattern) that represents what the similar tuples have in common with the given tuple. 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 here. Alternatively, a A||Go web service is available to compute concepts of neighbours without bothering about any setup.
