Ontological proximity disambiguates entities in the text by looking at relationships between entities that have been matched in the gazetteers. Entities that have a close ontological relationship are deemed to be more likely to be correct. For example, if analysis of a given document identifies both David Cameron (Prime minister) and David Cameron (football player/ manager) and also Samantha Cameron, then David Cameron (Prime minister) will be disambiguated due to the close ontological relationship with his wife. This is a powerful tool, and is where the value of the pns:notablyAssociatedProperty becomes apparent. By building (binding) the software that performs disambiguation by ontological proximity only to this relationship we gain powerful disambiguation, while retaining the ability to extend our ontology (and join to other cohesive public domain ontologies) without breaking the semantic annotation code.
