M-trees are used to organize and define fast queries on large databases of Attributed Graphs. In classical schemes based on metric trees, the routing information stored in a routing tree node is a selected Attributed Graph from the sub-cluster the node represents. Depending on the sub-cluster and the application, it is difficult to select a good representative of the sub-cluster. To that aim, we propose to use Generalized Median Graphs as the main information kept in the routing nodes of the m-tree. Experimental validation shows that in database queries, the decrease of the nodes explored in the m-tree while using a Generalized Median Graph is about 20% respect using a selected Attributed Graph.
