21. The computing system of claim 20 , calculating a first node score and a first edge score corresponding to said first ontology, wherein said calculating calculates said first match score as the sum of said first node score and said first edge score.
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.
