ERROR CORRECTION USING FACT REPOSITORIES
First Claim
Patent Images
1. A method for correcting error in digital text using fact repositories, comprising:
- searching computer data repository storing information for one or more relevant facts associated with input digital text;
extracting one or more facts postulated in the input digital text;
comparing said one or more facts postulated in the input digital text with said one or more relevant facts;
analyzing one or more differences between said one or more facts postulated in the input digital text and said one or more relevant facts resulting from the comparing step; and
transforming the input digital text into corrected digital text by correcting the input digital text using evidence resulting from the analyzing step.

Abstract
The disclosed system and method apply stores of factual information to correct errors in digital text, for example, generated from OCR, speech and/or handwriting recognition devices, and other automatic recognition devices. A text produced by OCR, speech recognition, handwriting recognition, and others may be processed to extract discussed facts. Databases of facts are searched based on information in the text. After comparing facts asserted in the text with the factual data from the databases, suggested corrections of the text are produced.

8. A system for error correction using fact repositories, comprising:
-
one or more fact repositories stored on one or more storage devices; and a correction module executable on a computer processor, the correction module operable to search the fact repositories for one or more relevant facts associated with input digital text, the correction module further operable to extract one or more facts postulated in the input digital text and determine one or more differences between said one or more facts postulated in the input digital text and said one or more relevant facts retrieved from the fact repositories, the correction module further operable to transform the input digital text into corrected digital text using evidence resulting from the determined differences. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform a method of modeling and evaluating impact on service components, comprising:
-
correcting error in digital text using fact repositories, comprising; searching computer data repository storing facts for one or more relevant facts associated with input digital text; extracting one or more facts postulated in the input digital text; comparing said one or more facts postulated in the input digital text with said one or more relevant facts; analyzing one or more differences between said one or more facts postulated in the input digital text and said one or more relevant facts resulting from the comparing step; and transforming the input digital text into corrected digital text by correcting the input digital text using evidence resulting from the analyzing step. - View Dependent Claims (19, 20)
