Similarity measures

Similarity measures based on:• common terminology• description logic • structural approach

(defResource c1::Client--NounPhrase (rdf:type owl:Class)(owl:intersectionOf TRRSL:NounPhrase

(owl:Restriction (owl:onProperty TRRSL:nounLink)(owl:allValuesFrom TY::order2))(owl:Restriction

(owl:onProperty TRRSL:isPartOfDomainStatement_d1e3741)(owl:allValuesFrom c2::order--DomainStatement))))

Showing similarity

Showing elements for reuse

Summary – evolution or revolution?
