DISKs : a system for distributed spatial group keyword search on road networks
Query (e.g., shortest path) on road networks has been extensively studied. Although most of the existing query processing approaches are designed for centralized environments, there is a growing need to handle queries on road networks in distributed environments due to the increasing query workload...

| الملخص: | Query (e.g., shortest path) on road networks has been extensively studied. Although most of the existing query processing approaches are designed for centralized environments, there is a growing need to handle queries on road networks in distributed environments due to the increasing query workload and the challenge of querying large networks. In this demonstration, we showcase a distributed system called DISKs (DIstributed Spatial Keyword search) that is capable of efficiently supporting spatial group keyword search (S-GKS) on road networks. Given a group of keywords X and a distance r, an SGKS returns locations on a road network, such that for each returned location p, there exists a set of nodes (on the road network), which are located within a network distance r from p and collectively contains X. We will demonstrate the innovative modules, performance and interactive user interfaces of DISKs. |
