Maximizing Bichromatic Reverse Spatial and Textual k Nearest Neighbor Queries
The problem of maximizing bichromatic reverse k nearest neighbor queries (BRkNN) has been extensively studied in spatial databases. In this work, we present a related query for spatial-textual databases that finds an optimal location, and a set of keywords that maximizes the size of bichromatic reverse spatial textual k nearest neighbors (MaxBRSTkNN). Such a query has many practical application...
متن کاملMonochromatic and bichromatic reverse top-k group nearest neighbor queries
The Group Nearest Neighbor (GNN) search is an important approach for expert and intelligent systems, i.e., Geographic Information System (GIS) and Decision Support System (DSS). However, traditional GNN search starts from users’ perspective and selects the locations or objects that users like. Such applications fail to help the managers since they do not provide managerial insights. In this pap...
متن کاملOn Processing of Continuous Bichromatic Reverse k-Nearest-Neighbor Queries
Bichromatic Reverse k-Nearest-Neighbor (BRkNN) query is a variant of the Reverse k-Nearest-Neighbor (RkNN) query that involves a set of service sites (e.g. gas stations) and a set of customer points (e.g. vehicles). It has many applications in Location-Based Services, in particular in mobile advertising. This paper investigates the processing of continuous BRkNN (CBRkNN) queries where the point...
متن کاملMethod for Maximizing Bichromatic Reverse Nearest Neighbor in Road Networks
The problem of optimal location query in road networks is proposed in this paper. Use of the idea of maximizing bichromatic reverse nearest neighbor, the optimal location set that attracts the largest number of clients in the road network is found, where the user can choose appropriate location and establish new service point. To address this problem, effective point set of all single-client po...
متن کاملEfficient Method for Maximizing Bichromatic Reverse Nearest Neighbor
Bichromatic reverse nearest neighbor (BRNN) has been extensively studied in spatial database literature. In this paper, we study a related problem called MaxBRNN: find an optimal region that maximizes the size of BRNNs. Such a problem has many real life applications, including the problem of finding a new server point that attracts as many customers as possible by proximity. A straightforward a...
