摘要：Point of interest (POI) sequences also called as route collections obtained from GPS/GIS enabled devices helps commuters reach their destinations faster by using the sorted routes information obtained from the route collections. This sorting process involves path query evaluation on large disk resident route collections that are regularly updated. Updates involve additions and deletions of routes. Previously graph based procedures offered sorted solutions, they had huge computation overhead. So we propose to use generic search-based paradigms that exploit transitivity information within the routes, and differ in their expansion phase using fast index maintenance procedures such as Link Traversal Search (LTS-k) algorithms along with maintaining secondary indexes for faster retrieval process. The proposed system offers better performance driven aspects leveraging on reduced computations and a practical implementation validates the claim
