Upload a Database File		Upload a Query File

Treepi selects frequent subtrees of a database as the index set. A tree-partition based query processing scheme is proposed to perform graph queries. The concept of center distance constraints is introduced to prune the search space. Last, the final verification of subgraph isomorphism test is performed by utilizing the location information of indexing structures.
