Using tree-grammars for training set expansion in page classification

Abstract

In this paper we describe a method for the expansion of training sets made by XY trees representing page layout. This approach is appropriate when dealing with page classification based on MXY tree page representations. The basic idea is the use of tree grammars to model the variations in the tree which are caused by segmentation algorithms. A set of… (More)
