24. The computing system of claim 21 , wherein calculating calculates said first edge score according to: EdgeScore = ∑ i ∈ M ⁢ ⁢ E ⁢ ⁢ E i + ∑ J ∈ MHE ⁢ ⁢ H j wherein, ME is a first set of edges matching corresponding edges of interest in said search request, wherein the nodes linked by a edge in said first set of edges matches the nodes linked by a corresponding matching edge of interest and said edge and said corresponding matching edge of interest are of the same relationship type, Ei is the weight of a corresponding edge in said first set of edges, MHE is a first set of half edges matching corresponding edges of interest in said search request, wherein the nodes linked by a half edge in said first set of half edges matches only one of the nodes linked by a corresponding matching edge of interest and said half edge and said corresponding matching edge of interest are of the same relationship type, and Hj is the weight of a corresponding half edge in said first set of half edges.
