Appeal No. 2000-0222
Application No. 08/938,044
BACKGROUND
Appellant's invention relates to a optical character recognition system having a
context analyzer. An understanding of the invention can be derived from a reading of
exemplary claim 1, which is reproduced below.
1. An optical character recognition (OCR) system comprising:
means for producing a scan of an input image of text to be
recognized;
a context analyzer coupled to receive the scan, for checking the
scan for consistency with a predetermined text content constraint, the
predetermined text content constraint including a syntactical constraint
and a semantic constraint;
user input means for accepting user-selected text content
constraints, including a character-based syntactical constraint and a
character-based semantic constraint, the user input means including a
document specification language which serves as a user interface to allow
the user to enter the user selected text content constraints;
syntax means for checking the preliminary scan for consistency
with the character-based syntactical constraint; and
semantics means for checking the preliminary scan for consistency
with the character-based semantic constraint.
The prior art reference of record relied upon by the examiner in rejecting the
appealed claims is:
