With the proliferation of geo-textual objects on the web, extensive efforts have been devoted
to improving the efficiency of top-k spatial keyword queries in different settings. However …

This article addresses the MaxRS (Maximizing Range Sum) monitoring problem. Given a set
of weighted spatial stream objects, this problem is to monitor a location of a user-specified …

This paper studies the problem of k-optimal-location-selection (kOLS) retrieval in metric
spaces. Given a set DA of customers, a set DB of locations, a constrained region R, and a …

Spatial information analysis has gained increasing attention in recent years due to its wide
range of applications, from disaster prevention and human behavioral patterns to …

Given a set S of sites and a set O of objects in a metric space, the Optimal Location (OL)
problem is about computing a location in the space where introducing a new site (eg, a retail …

This paper presents a novel Multi-criteria Optimal Location Query (MOLQ), which can be
applied to a wide range of applications. After providing a formal definition of the novel query …

A variety of optimal location problems have been extensively studied in the literature.
However, limited visualization systems have been developed for illustrating optimal location …

In recent years, geospatial data have been produced in mass eg, through billions of
smartphones and wearable devices. Current exponential growth in data generation by …

In this demonstration, we present a visualization system offering two advanced solutions that
can efficiently address a novel multi-criteria optimal location query by using Overlap** …
