graph into a compact and small-scale graph
while retaining the structure and attribute information of the original graph.With the increasing size of graph,graph data be-
comes difficult to query and store.Distance-based queries,such as shortest path queries,depend heavily on the size of graph.
In this paper,a distance query-oriented attribute weighted graph aggregation algorithm is proposed,which not only guarantees
the similarity of structure and attributes between nodes,but also preserves the distance between nodes,and effectively reduces
the size of the graph.The experiments prove that this method is effective and efficient in the query tasks.
Key words: graph aggregation;graph query;distance preserving;structure similarity;attribute entropy
