Method for retrieving texts which are similar to a sample text
First Claim
1. A method for using a sample text to locate and retrieve texts similar to the sample text from a database, the method comprising the steps of:
- providing an image of the sample text for locating and retrieving texts similar to the sample texts;
applying an optical character recognition process to the image of the sample test after providing the image of the sample text to obtain a sequence of charter codes which represents the sample text;
automatically producing search parameters from the sequence of character codes; and
using the search parametes to locate at least one text in the database which is similar to the sample text.

Abstract
An information retrieval method wherein users may submit a query via a graphical bitmapping technique. The user provides an information retrieval system with a bitmap of a printed, written, or graphical query by either scanning the query with a graphical scanner, or employing a standard facsimile transmission machine. The information retrieval system then performs an optical image/character recognition process upon the received bitmap to determine the content of the query, information is then retried based upon the recognized characters and images. In a particular method of the invention, the user is provided with a bitmap of the retrieved information.
