Abstract

"The Spatial Relation Query (SRQ) tool is a graphical. software system, supported by a SQL-like query language,. that enables users to perform information extraction driven. by the visual appearance and the spatial arrangement of the. information. The tool has been initially designed to support. visual information extraction from web pages. Indeed, its former. underlying spatial relation formalism relied on the bounding. boxes of the graphical objects, which is a suitable choice for the. web domain. In this paper we present a theoretical extension of. the SRQ spatial composition framework that has been enhanced. to work directly on the contours of the graphical objects. This. allows us to apply the tool to more general contexts, such as GIS. applications."
