Title
Generation Of Hypergraphs From The N-Best Parsing Of 2d-Probabilistic Context-Free Grammars For Mathematical Expression Recognition
Abstract
We consider hypergraphs as a tool obtained with bi-dimensional Probabilistic Context-Free Grammars to compactly represent the result of the n-best parse trees for an input image that represents a mathematical expression. More specifically, in this paper we propose: i) an algorithm to compute the N-best parse trees from a 2D-PCFGs, ii) an algorithm to represent the n-best parse trees using a compact representation in the form of hypergraphs, and iii) a formal framework for the development of inference algorithms (inside and outside) and normalization strategies of hypergraphs.
