Rule based information leveraging from business invoices

摘要

Invoices are interchanged between business organizations on a day-to-day basis, and they all contain the similar kind of information i.e. What is the name of issuing company? To whom is it issued? What is the amount of the invoice? What is the mode of payment? Capturing and structuring this information can give floor to critical supply chain and cash flow questions and help business analysts make better decisions. In order to represent data with irregular or hidden structure, semi structured data allows a ¿¿¿schema-less¿¿¿ description format in which the data is loosely constrained than in usual database system. In this paper annotation is used on the basis of some rules to add more structure to business invoices in order to simplify and standardize the storage and retrieval of business information.
