Relaxed Reverse Nearest Neighbors Queries
Given a set of users U , a set of facilities F , and a query facility q, a reverse nearest neighbors (RNN) query retrieves every user u for which q is its closest facility. Since q is the closest facility of u, the user u is said to be influenced by q. In this paper, we propose a relaxed definition of influence where a user u is said to be influenced by not only its closest facility but also ev...
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 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 کاملMaximizing 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 کاملVertical-Line-Based Incremental Algorithms for Moving Objects of the Monochromatic and Bichromatic Reverse Nearest Neighbors
Due to wireless communication technologies, positioning technologies, and mobile computing develop quickly, mobile services are becoming important on the spatial database management. One of the most important topics in the spatial information query processing is the Reverse Nearest Neighbor query (RNN query). There are two types of the RNN query problem: Monochromatic and Bichromatic RNN querie...
