This report covers the abstract concepts behind, as well as an implementation of, an automated heuristic RDF repair system for the Semantic Web. This student project formed a part of the Eyeball software originally written by Chris Dollin. This document also details the new availability of Eyeball as a web service, including its gathering of statistics. The web service was made available to the Jena community on 6th September 2006 on an HP external server at http://jena.hpl.hp.com:5500, and analysis of some of the statistics gleaned from its usage since that time are included. 30 Pages
