22. The computing system of claim 21 , wherein said first ontology of said set of ontologies contains a first set of nodes matching corresponding nodes of interest in said search request, wherein said ontology server computes a first match score and said first node score according to: NodeScore = ∑ I ∈ M ⁢ ⁢ C ⁢ ⁢ N i + ∑ J ∈ M ⁢ ⁢ I ⁢ ⁢ I j + ∑ k ∈ M ⁢ ⁢ P ⁢ ⁢ P k wherein, MC is a first subset of said first set of nodes containing nodes of type “concept”, Ni is the weight of a corresponding node in said first subset, MI is a second subset of said first set of nodes containing nodes of type “instance”, Ij is the weight of a corresponding node in said second subset, MP is a third subset of said first set of nodes containing nodes of type “property”, and Pk is the weight of a corresponding node in said third subset.
