There is an official gazette. The gazette discloses a technique of performing a morphological analysis of an input sentence, identifying a word constituting the sentence and the part of speech of the word, and performing a syntax analysis of the input sentence based on the result of the authentication, which has a modification relationship. If there are several possible combinations of the predicate and the required case, the distance between the combined predicate and the required case is scored, and the combination of the highest scoring predicate and the required case is obtained. Are determined to be in the correct qualifying relationship, and high-precision parsing is performed.

[0003]

However, the prior art described above only improves the accuracy of syntactic analysis, and determines whether the subject and predicate of a prepared sentence are too far apart. In addition, it is impossible to urge the user to proofread sentences.

In view of the above problems, in the present invention, the readability of a sentence depends on the number of words, which is the minimum unit of the sentence structure existing between the subject and the predicate in the sentence. Therefore, the subject and the predicate in the sentence are specified based on the morphological analysis information of the sentence, and a warning message is displayed when the number of words existing between the specified subject and the predicate is a predetermined number or more. Therefore, it is an object of the present invention to provide a sentence proofreading apparatus and a sentence proofreading processing method for prompting a user to proofread a sentence.

The storage unit 30 includes a ROM and a hard disk for storing various programs and data including a program for causing a computer to execute the document proofing method of the present invention, and a RAM for storing the programs and data as needed. It is preferable to use a storage device such as this.

It is desirable that the text editing control unit 40 use a so-called microcomputer including a CPU, a RAM, a ROM, an I / O (input / output) interface, a timer, and the like. By executing the program stored and stored in the storage device such as the ROM, the hard disk, and the RAM described above, the functions of the text editing control unit 40, which will be described in detail later, are realized, and the operation of each processing procedure is controlled. can do.

The text editing control unit 40 further includes a text editing unit 401, a morphological analysis unit 402, and a text correction unit 403.
And a warning word number changing unit 404.

A sentence editing unit 401 performs input, display, and editing control of a Japanese sentence, that is, creation and editing control of a generally-known Japanese sentence, according to the type of an input key input from the input unit 10. At the same time, when a preset control key such as a period “.” Or an Enter key, which indicates the end of a sentence, is received, the Japanese sentence input up to the input of the control key is sent to the morphological analysis unit 402. Output. When an input of a function key or the like set as a control key for operating a setting / change function of the number of warning words 301 (warning word number changing means 404) is received from the input unit 10, the number of warning words changing unit 404 is used. Is operated, and the numerical value and the like input from the input unit 10 are updated to the new warning word number 301.
Is output to the warning word number changing unit 404.

The morphological analysis unit 402 includes a text editing unit 401
The output Japanese sentence is analyzed using a word dictionary for morphological analysis (not shown), and the part of speech of the word (including analysis of the conjugation form of the word) is analyzed. The proofreading unit 403 is operated to output the morphological analysis information to the sentence proofreading unit 403.

The sentence proofreading unit 403 receives the output result of the morphological analysis information of the Japanese sentence analyzed by the morphological analysis unit 402 and determines whether the number of words existing between the subject and the predicate is appropriate or not. 30 (the number of warning words 30)
In addition to checking using 1), when it is determined that the number of words is not appropriate, a warning message is output to the display unit 20.

The number-of-warning words changing unit 404 includes a sentence editing unit 4
In response to the request of No. 01, a predetermined number (the number of warning words 301) stored in the storage unit 30 is set and changed.

Next, the function of the sentence proofreading unit 403 will be described in detail. The sentence proofreading unit 403 includes a word specifying unit 403a for specifying a word that can be a predicate by itself based on morphological analysis information of a Japanese sentence. Particle specifying means 40 for specifying a particle attached to a subject based on morphological analysis information of a Japanese sentence
3b, a positional relation confirming means 403c for confirming a positional relation between the particle and the verb in the Japanese sentence, and a counting means for counting the number of words existing between the subject and the predicate from the positional relation between the particle and the verb. Determining means 403e for determining whether or not the number of words existing between the subject and the predicate is equal to or more than a predetermined number using the number of warning words 301 stored in the storage means 30;
And a warning unit 403 for displaying a warning message on the display unit 20 when it is determined that there are more words than the predetermined number.
f. The warning message is not limited to being displayed on the display unit 20 and may be any message that can warn the user of the grammar proofreading device by giving a warning by voice output or the like. Thus, the sentence proofreading unit 403 identifies the subject (particle) of the sentence and the predicate (declarative) by using the constituent means provided by the sentence proofreading unit 403, and thereby the number of words existing between the subject and the predicate of the sentence Is checked, and if the number is equal to or more than a predetermined number, a warning message can be displayed.

Next, the sentence proofreading process of the sentence proofreading apparatus of the present invention will be described with reference to FIG. FIG. 2 is a flowchart showing the processing procedure of the sentence proofreading processing method of the present invention.

First, when the text editing unit 401 receives an input of a control key indicating the end of one sentence such as a period "." Or an Enter key from the input unit 10, the Japanese language input up to the input of the control key is received. The sentence is output to the morphological analysis unit 402 (S
201).

Next, the morphological analysis unit 402
In addition to morphological analysis of the Japanese sentence output from 01, part-of-speech information in words (including analysis of inflected forms of verbs)
Morphological analysis information consisting of Next, the Japanese sentence to which the morphological analysis information is added is output to the sentence proofreading unit 403 (S202).

Next, the sentence proofreading section 403 outputs
Using 03a, it is checked whether or not a verbal exists in the Japanese sentence to which the morphological analysis information output from the morphological analysis unit 402 is added (S203). If there is no verb, the process ends immediately, and if there is, a marker Y is added to the verb (S204).

Next, using the particle specifying means 403b, based on the morphological analysis information given to the Japanese sentence, the particle "ga"
Is checked (S205), and if so, a marker G is added to the Japanese particle "ga" (S206).

Next, using the positional relationship confirmation means 403c,
The marker Y immediately after the marker G in the Japanese sentence is searched (S207), and it is checked whether or not the utterance to which the first marker Y is attached is a closed form or a continuous form (S208). If neither of them is found, a search is made for a word to which the next marker Y has been added (S209).

When a terminating or continuous form is found, the number of words existing between the marker Y and the marker G is counted using the counting means 403d (S210).

On the other hand, if the particle "ga" does not exist in S205, it is checked using the particle specifying means 403a whether or not the particle "ha" exists based on the morphological analysis information given to the Japanese sentence. (S211). If not, the process ends. If there is, a marker H is added to the particle "ha" in the Japanese sentence (S212).

Next, using the positional relationship confirmation means 403c,
Search for the first marker Y after marker H (S
213), it is checked whether the utterance to which the marker Y is attached is a closed form (S214). At this time, since the subject of the noun-modifying clause does not take the particle "wa", it is not checked here whether or not it is a continuous form. If the word to which the marker Y has been assigned is not the final form, the next marker Y is searched (S215).

When an end word is found, the counting means 4
Using 03d, the number of words existing between the marker Y and the marker H is counted (S216).

Next, using the judgment means 403e, S210
And the number of words measured in S216 is compared with the number of warning words 301 stored in the storage unit 30 (S217). If the number of words measured in S210 and S216 is larger than the number of warning words 301, The warning unit 403f causes the display unit 20 to display a warning message such as "the subject is too far from the predicate and the sentence is difficult to understand" (S2).
18).

If the number of words counted by the counting means 403d is smaller than the number of warning words 301, the process ends without displaying anything.

The sentence proofreading device of the present invention performs the above sentence proofreading processing by using the above configuration, thereby counting the number of words existing between the subject and the predicate of the sentence, and determining the number of words between the subject and the predicate by a predetermined number or more. Since a warning message is displayed for a sentence having the number of words, the user can be prompted to proofread the sentence.

Next, the sentence proofreading process described above will be described more specifically with the following two sentences as examples. <Example sentences> a: Snow crabs lined up at the Osaka Central Wholesale Market early in the morning of December 8th. b: Greece is lagging behind economically in comparison to Ireland and other countries, which are starting to develop with the introduction of foreign capital.

First, an embodiment in the case where the text a is input will be described. When the text of “a” is input from the input unit 10 and the period “.” is input, the text editing unit 401
Is output to the morphological analysis unit 402 (S201). When the morphological analysis unit 402 morphologically analyzes the sentence a, the words forming the sentence a are given the following morphological analysis information.

[0035]

[Table 1]

The sentence a to which the morphological analysis information is added is output to the sentence proofreading unit 403 (S202). The sentence proofreading unit 403 performs each process by using each of the constituent units described above.
First, in S203, the sentence a to which the morphological analysis information is added
Since there is a verb that is a verb, the process proceeds to S204, and a marker Y is added to the verb "arranged". next,
In S205, the existence of the particle "GA" is checked. Since the particle "GA" exists, the process proceeds to S206, and the marker G is added to the particle "GA". At this point, the following information is added to the words constituting the sentence a.

[0037]

[Table 2]

Next, when the first marker Y located after the particle "ga" to which the marker G is attached is searched in S207, the verb "arranged" exists. In S208, this verb "arranged" is an end form, so the process proceeds to S210. S210
The number of morphologically analyzed words existing between the marker Y and the marker G is calculated as “8” as follows.

[0039]

[Table 3]

Proceeding to S217, if the stored number of warning words 301 is "7", a message such as "The subject and the predicate are too far apart to make the sentence difficult to understand" is displayed in S218.

Next, an embodiment in the case where the text of b is input will be described. When the sentence b is input from the input unit 10 and the period "." is input, the sentence editing unit 401 outputs the sentence b to the morphological analysis unit 402 (S201). Morphological analysis unit 40
2 morphologically analyzes the sentence b, the words constituting the sentence b are given the following morphological analysis information.

[0042]

[Table 4]

The sentence b to which the morphological analysis information is added is output to the sentence proofreading unit 403 (S202). The sentence proofreading unit 403 performs each process using each of the above-described constituent units.

First, in S203, since the sentence b to which the morphological analysis information is added has a verb as a verb, the process proceeds to S204, and the verb “grab”, “is”, “compared”
A marker Y is given to “I am late”. Next, S
Since there is no particle "ga" in 205, the process proceeds to S211. On the other hand, since the particle "ha" is included, the process proceeds to S212, and a marker H is added to the particle "ha". At this point, the following information is added to the words constituting the sentence b.

[0045]

[Table 5]

Since the sentence b has four markers Y indicating a word, in S213, when the first marker Y located after the particle "ha" to which the marker H is attached is searched, the verb "grab" is found. Exists. In S214, it is checked whether or not the verb "grab" is a final form. Since the verb "grab" is a continuous form, the process proceeds to S215, and it is checked in S214 whether the verb "aru" to which the next marker Y has been attached is the final form. In this case, since the verb "aru" is a continuous form, the process proceeds to S215 again, and it is checked in S214 whether the verb "Compare" to which the next marker Y is attached is the final form. In this case, since the verb "comparative" is a continuous form, the process proceeds to S215 again, and it is checked in S214 whether the verb "late" given the next marker Y is the final form.
As a result, the final form is only the marker Y4 assigned to the verb "late", and the process proceeds to S216. The number of morphologically analyzed words existing between the marker H and the marker G in S216 is counted as “16”.

[0047]

[Table 6]

In S217, if the stored number of warning words 301 is "7", a message such as "The subject and the predicate are too far apart to make the sentence difficult to understand" is displayed in S218.

As described in detail above, the sentence proofreading apparatus of the present invention determines whether or not the number of words existing between the subject and the predicate of a morphologically analyzed sentence is appropriate, based on the above-described configuration requirements and processing procedures. Check, if there is more than a predetermined number of words, a warning message can be displayed,
The user can be encouraged to proofread a sentence.

Next, as described above, the predetermined number (the number of warning words 301) stored in the storage unit 30 to be compared in S217 can be arbitrarily set and changed by the user as described above. The setting / change processing of the number of warning words will be described with reference to FIG.

FIG. 3 is a flowchart showing a processing procedure for setting a predetermined number used in the sentence proofreading apparatus of the present invention to determine whether the number of words existing between the subject and the predicate of a sentence is appropriate.

The sentence editing unit 401 changes the setting of a predetermined number (the number of warning words 301) of the number of warning words.
When an input of an operation control key (function key or the like assigned in advance) for operating is activated from the input unit 10, the warning word number changing unit 404 is activated. The activated warning word number changing unit 404 waits until a new numerical value is input from the input unit 10 via the text editing unit 401 (S).
301).

Next, when a new set numerical value is input, this numerical value is updated and recorded as a new predetermined number of the number of warning words 301 stored in the storage unit 30 (S30).
2), end the process.

Thus, the user of the sentence proofreading apparatus can determine the predetermined number used for determining whether or not the number of words existing between the subject and the predicate, which contributes to the easy-to-read sentence, is appropriate. And settings can be changed arbitrarily according to the sentence sense of the user.
It is possible to prompt the user to proofread a sentence that is easy to read according to the type of sentence created by the user and the user's feeling.

[0055]

According to the sentence proofreading apparatus and the sentence proofreading processing method of the present invention, the subject and the predicate are specified from the morphologically analyzed sentence, and the number of words existing between the subject and the predicate in the sentence is appropriate. And a warning message can be displayed if the number of words is equal to or greater than a predetermined number, so that the user can be prompted to proofread the sentence.
