Latest Patents
One of Xuming Meng's latest patents is a "Fast graph query engine optimized for typical real-world graph instances whose small portion of vertices have extremely large degree." This invention accelerates graph querying by caching neighbor vertices (NVs) of super-node vertices. In this embodiment, a computer receives a graph query (GQ) to extract result paths from a graph in a database. The GQ consists of a sequence of query vertices (QVs) and a sequence of query edges (QEs). The computer successively traverses each QE and QV to detect paths of the graph that match the GQ. During this process, if the current graph vertex (CGV) is a key in a cache for graph vertices with excessive degree, the computer retrieves NVs from the cache. Otherwise, it retrieves NVs from the database. If the degree is excessive and the CGV is not a key in the cache, the computer stores the CGV as a key for the NVs in the cache.
