ABSTRACT: Visual Information Extraction (VIE) is a
technique that enables users to perform information extraction from visual
documents driven by the visual appearance and the spatial relations occurring
among the elements in the document. In particular, the extractions are
expressed through a query language similar to the well known SQL. To further
reduce the human effort in the extraction task, in this paper we present a
fully formalized assistance mechanism that helps users in the interactive
formulation of the queries.
