Abstract (in Japanese) (See Japanese page) 
(in English) Recently, due to the lasting economic depression, an economical life has been desired for many people. For their assistance, our group is developing a Web-based receipt information system to help keeping household accounts to grasp daily expenses, and sharing latest information of selling products at nearby shops to buy products as inexpensively as possible. In this paper, we present the database design for this system, and propose the input data processing algorithm composed of the functions for 1) product name corrections, 2) discount price corrections, and 3) category classifications, to solve problems in the character recognition software on receipts adopted in this system. Our preliminary experiments found that this software often falsely recognizes product names, cannot correct discount prices, and cannot automatically classify categories of products. We implemented the proposed algorithm as a Java application, and applied it to 113 products from 12 receipts where every product was correctly processed.
