Abstract

PURPOSE:To prevent the comparison result that first and second form information are different from each other because of the existence of synonyms by referring to a dictionary where synonyms are stored to perform logical comparison. CONSTITUTION:A storage means 14 where plural pairs of synonymic character strings are stored and first and second comparing means 8 and 9 are provided, and the means 8 compares first and second form information 1 and 2 with a record as the unit, and form information are given to the second comparing means 9 as they are in the case of disaccord. This means 9 extracts character strings from both information to obtain a pair of character strings and compares these character strings with those stored in the storage means 14, and comparison is repeated until resulting in coincidence, and a result signal indicating the disaccord is outputted when this comparison results in disaccord. Thus, the comparison result that first and second form information 1 and 2 to be compared with each other are different because of the existence of synonyms is prevented to obtain the accurate comparison result.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a form comparison device that compares first and second form information and outputs a comparison result.

[Prior art] When comparing forms, there may be character strings that are logically the same because they have the same meaning even though they are different between the forms being compared, or the comparison may be difficult. There may be character strings that are excluded from comparison because they are unnecessary information.

Conventional techniques include storing two forms in a file and comparing them file by file, code by code, character by character, etc., but these are only physical comparisons, such as checking for synonyms. Because there was no such logical comparison, humans had to compare two forms to see if there were any differences.

For example, between two documents to be compared, one document has “
abc" and the other form uses the name 'def', the two strings actually have the same meaning, so you want to treat the two strings as equal. When two synonyms exist, physically the two forms are different, but even if you want to say that the two forms are logically the same, conventional comparisons will show that they are different. Go out and compare the two
It is necessary to review whether the two documents are equal.

[Problem to be solved by the invention] In this way, in the conventional comparison of physical form information, even if there are logically the same synonyms, the result is a different 11M form, and it is difficult for humans to compare the logicality. I will do it. Therefore, there are drawbacks such as oversights occurring and the need for a large amount of man-hours to redo the comparison.

An object of the present invention is to eliminate the above-mentioned drawbacks and to obtain accurate comparison results that do not result in comparison results in which the first and second form information to be compared are different due to the existence of synonyms. An object of the present invention is to provide a form comparison device.

[Means for Solving:lIi] According to the present invention, in a form comparison device that compares first and second form information on a record-by-record basis and outputs a comparison result signal indicating the comparison result on a record-by-record basis, , comprising a storage means for storing a plurality of pairs of agreed character strings, and first and second comparing means, the first comparing means storing the first and second form information. are compared in record units, and if they match, a result signal indicating a match is output as the comparison result signal, and the process moves on to the comparison of the first and 112 form information in the next record unit. If so, the above II in record units
and the second form information is given as is to the second comparing means, and the second comparing means is configured to: provide the first form information in record units received from the first comparing means
and a holding means for holding the second form information, respectively; character strings are extracted from each of the image information held in the holding means to form a character string pair, and this character string pair is stored in the storage means. If they match, the next character string is extracted from each piece of image information remaining in the holding means to form the next character string pair, and this character string pair is stored in the storage means. comparing the stored character string pairs and repeating this until the last character string pair extracted from the holding means, as long as this comparison yields a match;
When a result indicating a mismatch is obtained, a result signal indicating a mismatch is obtained, and when a result indicating a match is obtained for the character string pair last extracted from the holding means, a result signal indicating a match is transmitted from the holding means. There is obtained a form comparison apparatus characterized in that it has a processing means for outputting a comparison result signal and moving on to comparison of the first and second form information in the next record unit.

[Example] Next, an example of the present invention will be described with reference to the drawings.

Referring to FIG. 1, a form comparison bag W1100 according to an embodiment of the present invention compares first and second form information 101 and 102 on a record-by-record basis, and outputs a comparison result signal indicating the comparison result on a record-by-record basis. This is to be output to bag E4.

This form comparison device 100 includes a check-exclusion string storage means 14 that stores in advance a plurality of pairs of agreeing character strings as check-exclusion strings, and a first and second comparison means 8.
and 9.

The first comparing means 8 compares the first and second form information 101 and 102 record by record, and if they match, outputs a result signal indicating the match as the comparison result signal and performs the next step. Moving on to a comparison of the first and second form information 101 and 102 in record units, if they do not match, the second comparison means 9 directly uses the first and second form information 101 and 102 in record units. It is given to

The second comparing means 9 receives the first and second form information 101 in record units from the first comparing means 8.
and 102 (not shown), respectively.
and processing means (not shown) described below.

This processing means extracts a character string from each piece of image information held in the holding means, creates a character string pair, and converts this character string pair into a character string pair stored in the check excluded character string storage means 14. compare. At this time, if they match, the processing means extracts the next character string from each piece of image information remaining in the holding means, sets it as the next character string pair, and converts this character string pair into the check exclusion character. A comparison is made with the character string pairs stored in the string storage means 14, and this is repeated until the last character string extracted from the storage means, as long as a match is obtained in this comparison. The processing means transmits a result signal indicating a mismatch at the time when a result indicating a match is obtained for the character string pair extracted last from the holding means. A result signal indicating the above is outputted as the comparison result signal, and the process moves on to the comparison of the N1 and the second form information in the next record unit.

The structure of the form comparison device 100 according to this embodiment will be described in more detail below.

The form comparison device 100 of this embodiment includes a comparison file 1,
It is connected to the compared file 2, the parameter input device 3, and the output device 4, and the first human power means 5, the second human power means 6, the third input means 7, and the first comparison means 8, second comparison means 9, error processing means 10, and post-processing means 11
, result editing means 12, editing mode storage means 13,
and check exclusion character string storage means 14.

The comparison file 1 is a file that stores information on the forms to be compared, and the comparison file 1 is composed of, for example, a magnetic tape device, a magnetic disk device, or the like.

The compared file 2 is a file that stores information on the forms to be compared, and the compared file 2 is composed of, for example, a magnetic tape device, a magnetic disk device, or the like.

The parameter input device 3 inputs not only information on character strings to be excluded from the check for synonyms described above, but also information on character strings to be unconditionally excluded from the check to the form comparison device 100, and also inputs information on character strings to be excluded from the check for synonyms, and edits the comparison results. This is a device for inputting mode information to the form comparison device t100, and the parameter input device 3 is composed of, for example, a floppy disk device or a card reading device.

The output device 4 is a device that outputs the comparison results, and includes, for example, a magnetic tape device, a magnetic disk device, a printer, or the like.

The first human power means 5 reads information from the comparison file 1 record by record.

The second human power means 6 reads information from the compared file 2 in units of records.

The third input means 7 reads parameter information from the parameter input device 3 and stores it in the edit mode storage means 13 and the check excluded character string storage means 14.

The first comparison means 8 compares the information read by the first human power means 5 and the information read by the second human power means 6 on a record-by-record basis.

The second comparing means 9 receives the information of the comparison file 1 and the compared file 2 from the first comparing means 8 when the result of the comparison by the first comparing means 8 is a mismatch, and separates the information from each other by spaces. The character strings are logically extracted in the state in which the character strings are extracted, the character strings are compared, and when the character strings differ, the check excluded character string storage means 14 is searched, and the different character strings are checked as check excluded characters for synonyms. Perform a logical comparison between strings and check for unconditional exclusion strings.

The error processing means 10 sends a message pointing out a different character string when the comparison result in the second comparison means 9 does not match;
Edit the message to provide detailed information at the time.

When the first manual means 5 and the second manual means 6 finish reading from both the comparison file and the compared file, the post-processing means 11 finishes reading the information from one file, but the information from the other file does not. If the reading is not finished, the information is read from the file where the information remains, and processing is performed so that all information has been read from both files.

The result editing means 12 edits the number of different information, the number of character strings subject to check exclusion, etc. after post-processing is performed by the post-processing means 11, and also edits the end message.

The editing mode storage means 13 is a storage means for storing the editing mode of the comparison result.

The check exclusion character string storage means 14 is a storage means for storing information on character strings to be excluded from the check for synonyms and information about character strings to be unconditionally excluded from the check.

Next, the operation of the form comparison device of this embodiment configured as described above will be explained.

In this form comparison device, first, the third input means 7 inputs parameter information from the parameter input device 3 specifying the editing mode of comparison results, check exclusion character strings for synonyms, and character strings to be checked unconditionally. If the information is edit mode information, it is stored in the edit mode storage means 13,
If the information is a check exclusion string for synonyms or an unconditional check exclusion string, it is stored in the check exclusion string storage means 14.

Next, the first manual means 5 reads information record by record from the comparison file 1, and similarly, the second manual means 6 reads information record by record from the compared file 2.
This information is passed to the first comparison means 8.

The first comparison means 8 compares the two pieces of information record by record, and if they are equal, the edit mode storage means 13
If the editing mode is a mode that outputs information when the editing mode is equal, the information read from comparison file 1 is output to the output device 4, and if the editing mode is a mode that does not output, it is not output. , and then returns to the processing of the first human power means 5 and the second human power means 6 in order to repeatedly compare the next information. Further, when the two pieces of information are different, the two pieces of information are passed to the second comparing means 9.

The second comparison means 9 logically extracts character strings separated by spaces from the two pieces of information determined to be different by the first comparison means 8, compares the character strings with each other, and compares the two characters. When the strings are physically different, the check exclusion string storage means 14 is searched, and if the different strings are check exclusion strings with synonyms, the two strings are considered to be equal. If the string is considered to be an unconditional check exclusion string, it is logically compared and excluded from comparison.

At this time, if the same character string does not exist in the check excluded character string storage means 14, the two character strings are compared as logically different character strings.The two pieces of information are sent to the error processing means 10. hand over. When the two character strings are logically equal, the next character string is extracted and the process of the second comparison means 9 is repeated again.

The second comparison means 9 repeats the comparison until there are no more character strings in the two pieces of information being compared, and if there are no character strings that are physically or logically different until the end, the second comparison means 9 It is determined that the two pieces of information are equal, and the result mode storage means 13
The data is output to the output device 4 according to the editing mode, and the process returns to the first human power means 5 and the second human power means 6 again.

The error processing means 10 edits and outputs the message displaying the different character string by the second comparison means 9 so as to output the message instructing the detailed information at that time together with the two pieces of compared information. Output to device 4. Thereafter, the processing returns to the first human power means 5 and the second human power means 6 and the comparison is repeated.

Error processing 1 from the first human power means 5 and the second human power means 6
The processing up to 0 is repeated until all the information of either the comparison file 1 or the compared file 2 has been read, and after the information of either of the files has been read, the processing is transferred to the post-processing means 11.

The post-processing means 11 has finished reading all the information in either the comparison file 1 or the compared file 2, but the information in the other file has not finished reading, and there is still some information left. At the same time, all of the remaining information is read, and the read information is output to the output device 4 along with a message that there is excess information, and all information of both the comparison file 1 and the compared file 2 has been read. do.

The result editing means 12 edits the number of different pieces of information and the number of character strings excluded from checking as a result of a series of comparison processes after the post-processing means 11 has finished reading all the information of the two files. , and also edits the end message and outputs it to the output device f4, and the form comparison device t100 ends the process.

[Effects of the Invention] As explained above, the present invention is configured so that a comparison result in which the first and second form information to be compared are different due to the existence of synonyms will not be obtained. This has the effect of reducing the number of parts that need to be compared, reducing human errors such as oversights, and reducing the amount of man-hours required for humans to perform comparisons.
