Abstract

In this paper we present the Spatial Relation Query tool, a graphical software system for Information Extraction based on the visual appearance of the information. The SRQ tool is provided with a query language similar to the wellknown SQL, which allows users to write queries based on the visual arrangement of the information in an intuitive way. Two applications showing the use of the tool on web pages and geospatial data are presented.
