		<pub:abstract><![CDATA[Recognizing that two Semantic Web documents or graphs
are similar, and characterizing their differences is useful in many tasks,
including retrieval, updating, version control and knowledge base editing.
We describe a number of text based similarity metrics that characterize
the relation between Semantic Web graphs and evaluate these metrics
for three specific cases of similarity that we have identified: similarity in
classes and properties used while differing only in literal content, difference only in base-URI, and versioning relationship. When one graph is
judged to be a version of another, we generate a “delta” consisting of of
triples to be added or removed from one graph 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.
