Abstract

PURPOSE:To improve the input efficiency of a certain length of character string than that of one character when Japanese syllabary/Chinese character conversion is used as in the case of Japanese by indirectly designating the location of modification and properly modifying the result. CONSTITUTION:Hardware is assumed to be a general personal computer (CRT, keyboard, disk and CPU) configulation. An error is found and a cursor is moved to the head of a correct character string to be input. When a comparison modification mode is selected, for example, a state is brought about where correcting character string is acceptable. When the comparison modification mode is activated, a correcting character string input window is displayed under the cursor position to permit the correcting character string to be input while comparing it with the character string before modification. A corresponding character string having most number of characters coincident with the correcting character train and having shortest length of character train is selected in a range twice as long as the correcting character string. The corresponding character string is simply replaced with the correcting character string.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character string correction method, and more particularly to a user interface for correcting an electronic text by OCR input or key input. For example, it is applied to character recognition, editors, word processors and the like.

[0002]

2. Description of the Related Art The editing function of a conventional editor or word processor has a poor function for correcting an error in a text already digitized. The basic functions are deletion, insertion, and replacement, which are only performed in word units, character units, and line units. When correcting an error in a sentence that has already been input by some means, the error is deleted and the correct part is input. This is very troublesome depending on the mistake. For example, in the following cases, if there is an error such as "suppurative", if you enter "possible", "suppurative" will be replaced with "possible". Allow corrections.
Although the above example can be seen to be due to a mistake in Kana-Kanji conversion, a slightly different type of mistake occurs with OCR input. For example, if there is an error such as "Japanese language", enter "Japanese".

[0003]

[Purpose] The present invention has been made in view of the above-mentioned circumstances, and in the case of using Kana-Kanji conversion like Japanese, by indirectly specifying a correction point and appropriately correcting the result, The purpose of the present invention is to provide a character string correction method that allows a character string having a certain length to be input more efficiently than inputting one character.

[0004]

In order to achieve the above object, the present invention provides (1)
Input means for key-inputting a correction character string in a form including character strings before and after an error exists, and comparison means for comparing the character string input by the input means with a character string to be corrected.
Deciding means for deciding the character to be corrected based on the result of the comparing means, replacing the portion of the character to be corrected with the input character string, and (2) inputting the corrected character string to the corresponding character string. Displayed in the window displayed below
Marking the character string corresponding to the input modified character string, and further, (3) in (1) or (2) above,
When you input the modified character string by voice and recognize the voice,
Refer to the character string to be corrected, and further,
(4) In (1) or (2) above, if a special delimiter comes, force conversion is performed, and (5) In (1), (2) or (4) above. , The feature is that the last character of the modified character string is focused on and interactive editing is enabled. Hereinafter, an explanation will be given based on an embodiment (claim 1) of the present invention.

FIG. 1 is a flow chart for explaining an embodiment of a character string correction system according to the present invention. Less than,
The steps will be described in order. The hardware is not particularly limited, but it is a general personal computer (CRT, keyboard, disk, CPU) configuration. step1,2 : Move the cursor First, find the error and move the cursor to the beginning of the correct character string to be input. step3 : Selection of comparative correction function The correction method according to the present invention will be referred to as a comparative correction method. There is a comparison and correction mode as one mode such as the insert mode and the overwrite mode. When this mode is selected, the modified character string will be accepted.

[0006] step4: For input claims 2 correct answers string, at the comparison correction mode, display the corrected text input window under the cursor, the correction character string while comparing with the previous correction character string Can be entered. step5 : Determining the supported character string The supported character string is the character string that has the largest number of characters that match the modified character string within the range of twice the length of the modified character string, and that has the smallest character string length Choose. step6 : Swap the corresponding character string and the corrected character string Simply replace the corresponding character string with the corrected character string.

Next, a second embodiment (claim 2) will be described. Similar to the first embodiment, the input window of the correction character string is set below the corresponding character string, and the corresponding character string is somehow (for example, colored) according to the input of the correction character string.
Make a mark. This prevents accurate input and unexpected corrections. An example is shown in FIG.

Next, a third embodiment (claim 3) will be described. As for the hardware configuration, a general voice recognition device is connected to that of the first embodiment. The processing procedure is the same as in FIG. The correction character string is input by voice. The voice recognition result is obtained in the form of the score and the candidate character string. Therefore, the score of the portion that matches the correction target character is added, and the candidate character is set as the corrected character string with the voice recognition result having the highest score in the entire character string. If each character has no score, the score of the character string is divided by the number of characters to obtain the score of that character (see FIG. 3). The other parts are
This is the same as in the first embodiment.

Next, a fourth embodiment (claim 4) will be described. When the last character of the modified character string is a delimiter that is raised next, the delimited character is used as a key and the character string until the character is found is replaced with the modified character string. The other parts are the same as in the first or second embodiment. (Example of delimiters) ,,. ． ? ))}] Space code (example of replacement in case of delimiter) Modification target character string: Example 1 or ............... Example 2
Input string: Same as FIG. 3 of the third embodiment Modification result: Same as FIG. 3 of the third embodiment

Next, a fifth embodiment (claim 5) will be described. The procedure is the same as in the first and second embodiments or the fourth embodiment except that the character string corresponding to the input modified character string is interactively determined. A procedure for determining the corresponding character string will be described with reference to FIG. step1 : The character string from the cursor position to twice the length of the corrected character string is set as the search target character string. The last character of the modified character string is searched in order from the beginning of this search target character string. step2 : Replace up to the first found character position with the modified character string. Here, it is decided by the user's input whether to proceed to the next corresponding character or to decide. Space bar to
Within the search range, up to the next corresponding character is the replacement target range. When the space key is pressed and the last character of the modified character string cannot be found within the search range, the process moves to step 3. Confirm with carriage return. If the escape key is pressed here, the correction character string input state is restored.

Step 3: Make a sound and return to the state of inputting the corrected character string. Here, the correction character string is input or edited, the return key is returned, and the process returns to step 1. Further, the comparison correction mode can be ended by pressing the escape key. At this time, the character string is inserted as it is at the cursor position. Further, by pressing the return key without doing anything, the search range is further expanded by twice the length of the correction character string and the process returns to step 1. When the character string is edited here, the search range is reset to twice the length of the modified character string after editing. As described above, the present invention is capable of correcting an error, which is a basic function, by a simple and natural operation by editing a text using a computer.

[0012]

As is apparent from the above description, the present invention has the following effects. (1) In a system having an input means by voice recognition, this correction method enables comfortable correction. Because, when inputting aloud, it will not be properly recognized unless it has a certain amount of cohesion, and the portion to be corrected is not always a certain amount of cohesive length. Rather, such cases seem rare. In addition, this method has a function of improving reliability as an input unit for voice recognition. (2) By providing an extended correction function for the delimiter, more advanced correction can be performed. As the user gets used to it, it is an excellent user interface that can provide more advanced functions. (3) Being able to make interactive selections is an excellent interface that can be decided by the user and is suitable for the user level and improves learning speed for beginners.
