Title:
LINGUISTIC SUPPORT FOR A REGOGNIZER OF MATHEMATICAL EXPRESSIONS
Document Type and Number:
WIPO Patent Application WO2003071393
Kind Code:
A3
Abstract:
The present invention provides a new source of information, linguistic models, to improve the accuracy of mathematical expression (105). Specifically, the present invention is an extension of linguistic methods to the mathematical domain thereby providing recognition of the artificial language of mathematics in a way analogous to a natural language recognition. Parse trees (120) are the basic units of the mathematical language (1059, and a linguistic model for mathematics is a method for assigning a linguistic score to each parse tree. The models are generally created by taking a large body of known text (105) and counting the occurrence of various linguistic events (210) such as word bigrams in that body.
