Abstract

PURPOSE:To efficiently execute the document check by constituting this system so that the comparison is executed by constitution sentence units of two documents, respectively, and in the case a result of comparison is discrepany, it is informed to an operator and the operator who receives the notice designates a position in the document of a sentence whose comparison is to be restarted in the next time. CONSTITUTION:One sentence each is read out successively from the head sen tence A of documents 21, 22 and compared. When a third sentence is read out and compared, since both sentences do not coincide with each other, a sentence comparing part 1 detects it and informs it to a man-machine interface part 2. The man-machine interface part 2 informs a fact that both the sentences are discrepant to an operator by a display device, and also, informs its sentence position, as well, and the operator who receives the notice refers to the corrected document 22 of a document file 12, and decides a fact that its third sentence is an inserted sentence. Therefore, the operator instructs a sentence position in the document files 21, 22 whose comparison is to be restarted in the next time to the man-machine interface part 2. In such a way, the document check is executed efficiently.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for verifying document files, and more particularly to a method for verifying document files created in a word processor.

Traditionally, when verifying a word processor document file,
This is done by sequentially reading files from the beginning of the document in physical recording units and comparing them.

When creating a document using a word processor, the document is often revised, but if you want to find differences between the original and revised documents, read each physical recording unit of the two document files from the first sentence and read the last sentence. It is a method that allows you to compare up to

However, in such conventional methods, when a sentence is inserted, deleted, or replaced in a document, or when a character is added or deleted, the modified sentence and the characters after that character are There is a drawback that the contents of all of them do not match, and therefore, it is no longer possible to detect differences.

Kuhada Godan (1) An object of the present invention is to provide a document file verification method capable of detecting differences between two documents before and after partial modification.

According to the present invention, a sentence comparison means for reading and comparing the contents of two document files in units of constituent sentences, and a notification means for notifying when the comparison results do not match, are provided. The present invention is characterized in that, in response to this notification, the sentence comparison is restarted by reading out the sentence in the document file from the position of the comparison re-execution start sentence inputted from the outside.

harakiri forgery The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a system block diagram of an embodiment of the present invention. In FIG.
The constituent sentences of the pre-correction document 21 and the post-correction document 22 are compared with each other. In this case, both sentences @21 and 22 are read out one by one starting from the first sentence A and compared. When the third sentence is read out and compared, the images and sentences do not match, so the sentence comparison section 1 detects this and notifies the man-machine interface section 2 of this.

The man-machine interface unit 2 notifies the operator that the two sentences are different through a display device, and also notifies the position of the sentence. The operator who received the notification refers to the revised document 22 in the document file 12 and
Determine whether the th sentence is the inserted sentence.

Therefore, the operator instructs the man-machine interface section 2 the next sentence position in the document file 21, 22 at which the comparison should be resumed. That is, in this example, the position of the third sentence C in the document 21 before correction, and the position of the fourth sentence C in the document 22 after correction.
This indicates the position of the second sentence C. After that,
Issue an instruction to resume sentence comparison. Therefore, from then on, a comparison is performed between sentences in which the comparison sentence positions of both documents are shifted by one from each other.

Sixth changed sentence E° of revised document 22 and pre-amended document 2
When the fifth sentence E of No. 1 is compared, the comparison unit 1 detects a mismatch and detects that there has been a change.

According to the present invention, two documents are compared in units of constituent sentences, and if the comparison results do not match, this is notified to the operator, who receives the notification and then performs the following operations. Since the document position of the sentence at which the comparison is to be restarted is specified at the time, document checking can be performed efficiently.

Claims (1)

[Claims] (1) Provide a sentence comparison means that reads and compares the contents of two document files for each component sentence unit, and a notification means that notifies you when the comparison results do not match, and in response to this notification, an external A document file verification method characterized in that sentences in the document file are read from an input comparison re-execution start sentence position and sentence comparison is restarted.
