]> 1999-11-30T00:00:00-05:00 In addition to determining the similarity between two Semantic Web graphs, we generate a ’delta’ between graphs that have been identified as having a versioning relationship. The delta consists of triples to be added or removed from one to make them equivalent. This method takes into account the text of the RDF graph’s serialization as a document, rather than relying solely on the document URI.

We have prototyped these techniques in a system that we call Similis and evaluated its performance on several tasks using a collection of graphs from the archive of the Swoogle Semantic Web search engine.]]> 3088384
