Application of graphical models for invoice data extraction

Krzysztof Otto

Abstract

This paper defines a factor graph based language for modelling human-like reasoning about document contents. It also describes an efficient parallel algorithm for its evaluation and a simple textual description language designed to simplify model definition. The language and evaluation algorithm are used for extraction of important information from VAT invoices.

Abstract in Polish
Praca definiuje oparty na skierowanych acyklicznych grafach czynnikowych język modelowania sposobu rozumowania o zawartości dokumentów. Opisuje również wydajny, równoległy algorytm jego ewaluacji oraz stworzony dla ułatwienia pracy nad modelami prosty tekstowy język opisu i wykorzystuje go do wyodrębniania kluczowych informacji z faktur VAT.
