Example Computation of simavg. Computation of simavgon a DAG with six nodes. The target set is (black nodes) and the query set (nodes with horizontal lines). The IC value of a node is shown in a small, dashed, attached oval. The most similar terms for D and F are B and C respectively, because IC(B) > IC(A) and IC(C) > IC(B). Therefore, . Note that only terms involving nodes in were considered in the calculation.
