Claim One:
1. A computing system comprising: a memory storing processor-executable program code; and a processor to execute the processor-executable program code in order to cause the computing system to: determine a first tree comprising a first hierarchy of nodes and a second tree comprising a second hierarchy of nodes; determine first subtrees of the first tree which are identical to first subtrees of the second tree; generate a first mapping between nodes of the first subtrees of the first tree and nodes of the first subtrees of the second tree; generate a first feature vector for each of second subtrees of the first tree; insert the first feature vectors into an index structure; generate a second feature vector for each of second subtrees of the second tree; and generate a second mapping between nodes of second subtrees of the first tree and nodes of the second subtrees of the second tree based on the second feature vectors and the index structure.
