Abstract

Graph is an important data structure and is used in an abundance of real-world applications including navigation systems, social networks, and web search engines, just to name but a few. We study a classic graph problem – computing graph shortest-path distances. This problem has many applications, such as finding nearest neighbors for place of interest(POI) recommendation or social network friendship recommendation. To compute a shortest-path distance, traditional approaches traverse the graph to find the shortest path and return the path length. These approaches lack time efficiency over large graphs. In the applications above, the distances may be needed first (e.g., to rank POIs), whi..
