Skyline queries return a set of interesting data points that are not dominated on all
dimensions by any other point. Most of the existing algorithms focus on skyline computation
in centralized databases, and some of them can progressively return skyline points upon
identification rather than all in a batch. Processing skyline queries over the Web is a more
challenging task because in many Web applications, the target attributes are stored at
different sites and can only be accessed through restricted external interfaces. In this paper …

Skyline queries return a set of interesting data points that are not dominated by any other
point on all dimensions. Most of the existing algorithms focus on skyline computation in
centralized databases, and some of them can progressively return skyline points as they are
identified rather than returning the answer in a batch. Processing skyline queries over the
web is much challenging. One reason is that in many web applications, the target attributes
are stored at different sites, and they might not be available other than through external web …
