THE REJECTION BASED ON PIROLLI AND CALL
We begin our analysis with Call, which discloses converting natural
language text data into a series of integers in order to reduce storage space
requirements and permit more rapid processing than can be accomplished using
character data (Call para. 9).
Referring to Figure 1, incoming text data in “a conventional file, string or
character array as seen at 111” is parsed (at 115) into substrings consisting of
alphanumeric terms and punctuation terms 117 (id. para. 26). These terms are
compared (at 121) to the terms already stored in stored in term table 125 (id. paras.
26-27). If there is a match, the integer that has already been assigned to that term
is appended to the end of integer array 135 (id. para. 29). If there is no match, the
term is added to the term table as shown at 137 and a newly assigned integer is
appended (at 136) to the end of the integer array (id.). At the conclusion of the
parsing and storage process, the term table holds one copy of each unique substring
(both alphanumeric terms and punctuation terms) that appeared in the original text
data and the integer array holds an integer representing each term produced from
the parser in the order found, with one exception, which is that single spaces
between alphanumeric spaces are not represented (id. para. 30). The Examiner is
