Grid-partition index: a hybrid method for nearest-neighbor queries in wireless location-based services
Abstract Traditional nearest-neighbor (NN) search is based on two basic indexing approaches: object-based indexing and solution-based indexing. The former is constructed based on t...

Approximate Evaluation of Range Nearest Neighbor Queries with Quality Guarantee
The range nearest-neighbor (NN) query is an important query type in location-based services, as it can be applied to the case that an NN query has a spatial region, instead of a lo...
