Tree mining: pruned, embedded, and refined. In this example, the query tree Q1 is a pruned subtree and an embedded subtree of tree T; Q1 is also (trivially) refined within T. The query tree Q2 is an embedded subtree of T and also (trivially) refined in T; however, it is not a pruned subtree of T. The query tree Q3 is refined by T but is neither an embedded nor a pruned subtree of tree T.
