Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a Japanese word processor, a machine translation device, etc. for proofreading / revising Japanese.

[0002]

2. Description of the Related Art Conventionally, there are few document processing devices that perform Japanese proofreading / reviewing that perform parsing processing that is always performed by Japanese-English machine translators, etc. Most of them are morphological analysis processing and point out errors. Most did.

For example, the invention disclosed in Japanese Patent Laid-Open No. 4-213155 describes that morphological analysis processing is performed and typographical error candidates are output only when a more probable word sequence exists. . If there is an unregistered word that has not been registered in the word dictionary and a homonym whose connection cost is lower than the threshold value, that is, grammatically, by using the cost table that defines the appearance probability of the surface layer from the word part of speech and other information. Therefore, the typographical error candidate is output only when a certain word sequence exists.

Further, JP-A-62-150461 and JP-A-62-150462
A pair of adverbs and auxiliary verbs having a sympathetic relationship is stored in, and detection / correction is performed when there is no corresponding combination expression. This makes it possible to detect / correct a portion that may have an error in the usage of words having a synergistic relationship.

In Japanese Patent Laid-Open No. 62-209659, morphological analysis and syntactic analysis are performed, and a grammar with a constraint condition is used.
By pointing out the part corresponding to the constraint condition,
Supports proofreading.

[0006]

However, when the calibration / correction is performed by performing only the morphological analysis, the dependency relation is ignored, so that the typographical error can be corrected, but the dependency relation is clear. It may not be possible to calibrate / correct.

For example, the following two sentences will be taken as an example.

(1) "He saw a rest." (2) "He saw a rest." In these two sentences, "he" and "rest"? "saw"
It can be ambiguous. Generally, in the sentence (1), it is natural for "he" to look "far" in the distance, such as "he saw someone (resting) taking a break." ) Sentence, it is natural to understand that "(someone) saw him resting", such that "he" relates to a "resting" nearby.

Therefore, in the present invention, by performing a syntactic analysis, the dependency relation is analyzed, and when the dependency relation is ambiguous, the clause is moved to a position where the ambiguity is resolved,
By inserting a punctuation mark or a comma immediately after the dependency phrase of the dependency, the ambiguity of the dependency is resolved and the sentence is easy to read.

For example, in the resolution of ambiguity by moving clauses, (1a) "He saw a break.", And in resolution of ambiguity by reading points, (1b) "He took a break. I saw it doing. "

In this case, if there are more punctuation marks or commas than necessary, the sentence becomes rather difficult to read. Therefore, a syntactic analysis is performed and only ambiguity is inserted.

Also, in the case of parsing, instead of performing a special process of putting a constraint condition on the grammar as in the conventional technique, all the elements related to one idiom are recognized. In addition, case analysis is performed to compare with case patterns held as dictionary information, and word order is checked.

[0013]

A document processing apparatus of the present invention displays an editing means for inputting / editing Japanese, a storage means for storing a Japanese sentence input by the editing means, and the Japanese sentence. display means, and a dictionary storage means for storing a dictionary and grammar, and morphological analysis unit for performing morphological analysis on the basis of the stored dictionary and grammar to the dictionary storage means,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a document processing apparatus according to the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing an example of the configuration of a document processing apparatus according to the present invention. 1 is control means, 2 is input / editing means, 3 is display means, 4 is dictionary storage means, 5 is grammar storage means, 6 is morpheme analysis means, 7 is syntactic analysis means, 8 is input character storage means, and 9 is Phrase movement means, 10 is a check destination means, 11 is a comma insertion means, 12 is a phrase insertion means, 13 is a case pattern storage means,
Reference numeral 14 indicates a standard word order checking means.

Under the control of the control means 1, the input sentence input from the input means 2 is stored in the input character storage means 8. At the same time, this content is displayed on the display means. The morphological analysis unit 6 uses the dictionary of the dictionary storage unit 4 and the grammar of the grammar storage unit 5 to divide a sentence into phrases.

The syntactic analysis means 7 creates a syntactic analysis tree using the dictionary of the dictionary storage means 4, the case pattern of the case pattern storage means 13 and the grammar of the grammar storage means 5. From the syntactic analysis tree, the dependent check means 10 detects an ambiguous sentence related to the dependent, and the display means 3 displays the ambiguous sentence.
Also, the phrase moving unit 9 moves to a position where the ambiguity is resolved or reduced, and the comma insertion unit 11 inserts a reading point or a comma.

Further, the syntax analysis tree and case pattern storage unit 1
From the case pattern No. 3, the standard word order checking unit 14 checks whether or not they appear in the order of the case element standard, and the phrase moving unit 9 moves them.

FIG. 2 is a flow chart showing the processing of the present invention. FIG. 9 is a diagram showing an example of a screen display image. First, there is a main window that displays the text to be composed. If the full text cannot be displayed, it is possible to check the entire text by using a function such as scrolling.

In the present invention, since the processing is basically for each sentence, a window for displaying the sentence to be processed and the pointed out contents is prepared. In FIG. 9, it is shown as a “window showing the indication target sentence”. In FIG. 9A and FIG. 9B, the underlined clauses indicate the clauses that are better to be moved, and the blank frames indicate the positions to be moved.

A window in which the calibration operation is used as a menu is shown as a "calibration operation selection menu window".
"●" to select whether to follow the system's instructions
“O” indicates selection and non-selection, respectively, which can be changed / selected with a mouse or the like.

Although not shown in FIG. 9, a window for displaying the reason (content) of the problem may be displayed. For example, in the case of Fig. 9 (a), the display "There is an ambiguous phrase related to the person concerned. Are you sure you want to move the corresponding phrase to a position that can reduce the ambiguity?" The order of case particles for adjectives is different from the standard. Are you sure you want to change the standard word order? ”Is displayed.

FIG. 2 is a main flow. Step S1
Then, one input sentence is read into the input character storage means 8.
At the same time, a display is made on the display means 3. Step S
In 2, the morphological analysis unit 6 creates a clause using the dictionary of the dictionary storage unit 4 and the grammar of the grammar storage unit 5. In step S3, calibration support that can be performed at the morphological analysis level is provided. For example, it points out typographical errors and points out inconsistencies in word endings.

In step S4, it is judged whether the input sentence is changed or not based on the indication in the proofreading support performed in step S3, and if it is changed, the process proceeds to step S2 to perform the morphological analysis again. Return. If no change has been made, the process proceeds to step S6.

In step S6, a syntax analysis process is performed.
The syntax analysis algorithm is not special, but case analysis / semantic analysis using case patterns is performed.

In step S7, the calibration support is performed using the result of step S6. Details will be described with reference to the flows of FIGS. 3 and 4 and the example sentences of FIG. In addition, this FIG.
The order of the processes shown in FIG. 4 does not matter.

Next, with reference to FIG. 3, the processing when there is ambiguity in the dependency is shown. In step S11, as shown in FIG.
In the sentence like (1-3), the result of the syntactic analysis may have two types of dependency as shown in FIG. FIG. 7 shows a dependency structure, in which related words are arranged below the receiving word.
In Figure 7 (1-3a), "Book" and "Yesterday" are "Read",
Indicates that "buying" is related to "book", and (1-3b)
"Yesterday" is "buy", "buy" is "book",
It indicates that "reading a book" is related to "reading". FIG. 6 (1-3) shows this structure in the same manner. Using the contact check means 10, a phrase that may be at two places is searched from this structure, and "yesterday" is found. If there is a phrase that may be related to two or more places, the process returns to step S12, and if not, the process returns to the main flow.

In the case of the present embodiment, the case pattern of the case pattern storage means 13 is used to determine which of the two or more related parties is more likely to be related by performing case analysis and semantic analysis.

In FIG. 5 (1-1a), as shown in FIG. 6 (1-1a), "playing the guitar" is changed to "playing" at a farther position.
-1b), as shown in FIG. 6 (1-1b), relates to a closer phrase “singing”. Similarly, in the examples of (1-2a) and (1-2b) of FIG. 5, the example of (1-2a) relates to a farther bunsetsu . In this step, if the system determines that there is an ambiguous phrase related to the destination and that the farther one of the possible phrases related to the destination is involved, the process proceeds to step S12. Otherwise, return to the main flow.

That is, in the sentences (1-1a) and (1-2a) in FIG. 5, the process proceeds to step S12, and the sentences (1-1b) and (1-2b) in FIGS.
Statement returns to the main flow. In addition, in the example of (1-3), it cannot be determined whether "yesterday" relates to "buying" or "reading". In addition, "red" in Fig. 5 (1-4) and Fig. 6 (1-4).
It is not possible to determine whether is related to "company" or "car" (it can be determined if the knowledge that there is no "red company" is stored). In these cases as well, it is up to the user's judgment in step S12.

In step S12, the characteristic display (for example, color display, underline display, etc.) of the ambiguous phrase of the destination and the position of the destination are displayed. In the case of the sentence of (1-1a) in FIG. 5, "window showing the indicated sentence" in (1-1a) of FIG. 9
Is displayed. Also, selection items are displayed as in the “calibration operation menu window”. Here, the option of moving the phrase, inserting a reading point (or a comma), or leaving it as it is is displayed, and the process proceeds to step S13.

In step S13, the user selects from the display options in step S12, and the process proceeds to step S14.

In step S14, when the phrase movement is selected in step S13, the feature-displayed phrase is moved to the destination position. The destination is just before the clause of the destination. Also, when insertion of a reading point is selected, a reading point (or a comma) is inserted immediately after the phrase displayed as a feature. After each process is completed, the process returns to the main flow.

Next, the processing for checking the word order using case analysis and changing the word order will be described. In step S21, as a result of the syntactic analysis, it is analyzed what clauses are associated with which terms and in what order. By comparing this with the case pattern data, it is judged whether or not the word order is standard. For example, in FIGS. 5 (2-1) and (2-2),
The terms "written" include "book" and "me" in that order. In addition, in the verb "to regard", "correct answer" and "this" are related in this order. In this idiom,
Case pattern data is shown in FIG. If the order of each element of the case pattern is the standard word order, both are different. If it is different from the standard word order like this,
The process proceeds to step S22, and if they are not different, the process returns to the main flow.

In step S22, the phrase movement for displaying in the standard word order is displayed. That is, the phrase to be moved and the move destination are displayed as in the “window showing the indicated object sentence” in (2-1) of FIG. If there are three or more case elements, steps S21 to S24 are repeated.

Considering the change of word order as the movement of a clause that is a case element, the case element closest to the word in the standard word order is checked, and another case is inserted between the case element and the word in the input sentence. When the element is included, the destination is set just before the idiom. When it is repeated, each element next to the word is checked, and the destination is set immediately before the case element closest to the word that has finished moving first. After that, the process proceeds to step S23.

In step S23, the user selects whether to move. When moving, step S2
4. If not, return to the main flow.

In step S24, the feature-displayed clause is moved to the destination position. Then return to the main flow.

In step S7, the contents of the input character storage means 8 and the contents of the display means 3 are changed depending on the result of the calibration by the conventional calibration support function of step S3 and the result of the calibration by the calibration support function of the present invention of step S6. To be done.

If there is a next sentence in step S8, the process returns to step S1. If not, the process ends.

[0047]

As described above, according to the present invention, if a user's intention is that a farther destination is related to an ambiguous phrase, the phrase is placed immediately before the phrase. It is possible to move and proofread the sentence to eliminate or reduce ambiguity, and to accurately convey the reader's intention to the reader. In other words, if there is an ambiguous clause,
This phrase is displayed separately, and this phrase is moved.
Distinguishing display of moving positions that can resolve ambiguity
However, after displaying the distinction between this movement target clause and the movement position, this sentence
Instructs to move a clause and distinguishes this clause based on this instruction
You can move to the displayed position, and ambiguous dependency
The sex can be eliminated. Also, instead of moving the phrase, by inserting a punctuation mark or a comma immediately after the phrase, it is possible to implicitly convey to the reader that the phrase relates to a distant place and reduce ambiguity. It becomes possible. Further, by using the case analysis / co-occurrence information, it becomes possible to accurately determine the dependency. Furthermore, in Japanese, the word order of the case elements of idioms is relatively free, but the standard word order is fixed to some extent except for the purpose of special effects, which is easy for readers to understand. Therefore, by pointing out a non-standard word order and moving to a standard position, it is easy for the reader to understand.
