consolidation on the semantic web data graph. In In Proceedings
of I3: Identity, Identifiers, Identification. Workshop at 16th
International World Wide Web Conference (WWW2007).
This paper describes identities and the integration of data. They present a method for merging instances across multiple data sources (**large scale**). They describe how they determine two instances represent the same entity using inverse functional properties. Their dataset includes over 72 million instances (wow).
Key points:
- There isn't much agreement on use of common URIs to identify entities (optional in RDF) so URI represents multiple instances at times
- There is a lack of formal specification for determining equivalences among entities
- Existing methods that perform object consolidation rely upon probabilistic methods
- The use of inverse functional properties in the Semantic Web world is widely used
