Abstract

PURPOSE:To improve the register efficiency of a word dictionary file by registering a minimally necessary word in the word dictionary file since there are problems such as register repetition or the register omission of the word which should be registered in the register processing of the character-recognized word. CONSTITUTION:A word selection processing part 2 displays the word which is character-recognized and decided by a specified method in a display device 4, reads the specified word from the display device 4 by an input command and informs a word register processing part 3 of the word. The word register processing part 3 is constituted to retrieve the word dictionary file 5 with the word as a key and to register the word in the word dictionary file 5 unless the word is registered.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for processing recognized characters. In character recognition processing for reading handwritten characters and printed characters, words that make up customer names, customer addresses, etc. that are regularly input at financial institutions etc. can be registered in advance in a word dictionary file to facilitate character recognition processing. Although efforts are being made to improve the quality and processing efficiency, words that are incorrectly recognized are added to the word dictionary file after being corrected, so words that are not registered in the word dictionary file may not be correctly recognized. If a word is registered in the word file, the word may be registered incorrectly, and if a word already registered in the word file is incorrectly recognized, the word may be registered redundantly. There is a need to eliminate duplicate registrations and missing registrations in word dictionary files.

2. Description of the Related Art FIG. 5 shows a conventional system configuration diagram, and FIG. 6 shows a conventional processing procedure. The processing device 20 reads the characters written on the form 21, and in processing step 91, the character recognition unit 15 performs character recognition on the form, and creates a character code generated as a result of the character recognition as a candidate character. FIG. 4 shows an explanatory diagram of the form to be recognized and the recognition result.

In FIG. 4(a), the characters ``Naka'' and ``Kawa'' in the name field written on the form are recognized, and each character in the address field is also recognized. Characters that are compared with the standard character pattern and whose distance (similarity) to the standard character falls within a predetermined value are extracted from the characters held as character categories by the character recognition unit 15, and the characters ( character code). That is, as shown in FIG. 4(b), the recognition result characters are ranked in order of similarity, for example, the first candidate "Naka" and "Kawa".
However, the second candidates were decided as ``Ushi'' and ``Tsu.'' Recognition characters are determined for each character in the address field.

In processing step 92, the character recognition section 15 passes the recognition results determined as the first and second candidates to the word selection processing section 25 as candidate words. Processing step 93
Then, the word selection processing unit 25 displays the candidate word on the display device 45.

[0005] In processing step 94, the operator checks whether the displayed candidate word is the same as the character written on the form.
If corrections are necessary, the displayed contents are updated and input from the display device 45. In processing step 95, the word selection processing unit 25 reads candidate word data after operator confirmation from the display device 45, and checks whether or not there has been a change in the displayed content. If the displayed content has been updated, in processing step 96, the word registration processing unit 35 is requested to register the updated word. In processing step 97, the word registration processing section 35 additionally registers the updated word in the word dictionary file 55. If the displayed candidate words have not been updated, no additional words will be registered.

[0006]

[Problem to be Solved by the Invention] In character recognition processing, words (candidate words) generated as a result of character recognition are checked by an operator, and only the words that have been corrected are stored in the word dictionary file 55 by the word registration processing section 35. In order to be additionally registered, a word that is not registered in the word dictionary file 55 and needs to be registered may not be registered even if it is recognized normally, or even a registered word may be incorrectly recognized and corrected by the display device 45. If the word is input later, there is a drawback that the input word is registered in the word dictionary file 55 in duplicate.

An object of the present invention is to register the minimum necessary number of words in a word dictionary file.

[0008]

[Means for Solving the Problems] FIG. 1 is a block diagram of the principle of the present invention. Word selection processing unit 2 and word registration processing unit 3
, a display device 4, and a word dictionary file 5 in which words to be character-recognized are registered, and the word selection processing unit 2 displays words that are determined by character recognition and determined by a predetermined method on the display device 4. , reads a predetermined word from the display device 4 in response to an input command, notifies the word registration processing unit 3 of the word, and the word registration processing unit 3 searches the word dictionary file 5 using the word as a key, and searches the word dictionary file 5 using the word as a key. If the word is not registered, the word is registered in the word dictionary file 5.

[0009]

[Operation] The word selection processing unit 2 from the recognized characters,
The candidate word of the first candidate is displayed on the display device 4 to confirm whether character recognition is normal or not, and only the characters read in response to input instructions from the operator are not registered in the word dictionary file 5. By registering in the word dictionary file 5, it is possible to optimize the registration efficiency.

[Example] Figure 2 shows a system configuration diagram of the example, and Figure 3
shows the processing procedure of the example. The processing device 10 processes the form 11
In processing step 81, the character recognition unit 1 performs character recognition on the form, and creates a character code generated as a result of the character recognition as a candidate character. That is, as a result of character recognition of the form shown in Figure 4(a),
As shown in (b), the first and second candidate words are determined.

[0011] In processing step 82, the character recognition section 1 passes the candidate word to the word selection processing section 2. In processing step 83, the word selection processing unit 2 displays the candidate word on the display device 4. The displayed candidate words are processed in processing step 84.
The operator checks whether the characters are the same as those written on the form, and if corrections are necessary, the displayed contents are updated and inputted from the display device 4.

[0012] In processing step 85, the word selection processing section 2
Candidate word data after operator confirmation is read from the display device 4 and passed to the word registration processing section 3. Processing step 8
In step 6, the word registration processing unit 3 checks for each word whether the candidate word has already been registered in the word dictionary file 5,
If there are unregistered words, they are registered in the word dictionary file 5.

[0013]

Effects of the Invention: When registering a word in the word dictionary file 5 after a character is recognized, by checking whether the recognized word has already been registered in the word dictionary file 5, duplicate word registration can be avoided. This can prevent registration failures.
