Systems and methods for automatically correcting data extracted from electronic documents using known constraints for semantics of extracted data elements

摘要

In a document analysis system that receives and processes jobs from a plurality of users, in which each job may contain multiple electronic documents, to extract data from the electronic documents, a method of automatically correcting the extracted data using known constraints amongst semantics of extracted data elements is provided. The method includes: analyzing each electronic document in a job to automatically extract data; automatically analyzing the extracted data to identify incorrectly extracted data elements using rules defining constraints amongst semantics of extracted data elements; and automatically attempting to correct the incorrectly extracted data elements using the rules.
