Title: Optimal-Location Queries over Spatial Databases

Abstract: We study the optimal-location queries in spatial databases.
Given a set S of sites, a set O of objects, and a spatial region Q, the
optimal-location query returns a location in Q such that, if a new site is
put at that location, the total benefit to the objects is maximized. The
optimal-location queries are of interest in many applications such as
corporation decision-support systems. There may be multiple variations of
the optimal location because different applications may define the benefit
to the objects differently. In this proposal, we consider two most
intuitive definitions of the benefit. We also examine the problem under
different distance metrics. We expect that the work will not only advance
spatial database research, but also benefit the end users who deal with a
large volume of spatial data.
