Abstract

PROBLEM TO BE SOLVED: To provide a sentence proofreading device which improves the efficiency of proofreading work by preventing the erroneous correction of the word which is in a cooccurrence relation with a prescribed word when the prescribed word is changed to a near-synonym. SOLUTION: A sentence proofreading device is composed of a well known computer provided with a CPU, a ROM, and a RAM, an input device, a display device, etc. At the time of performing a sentence proofreading process, the device divides an inputted sentence into words by performing morphological analysis and converts an arbitrary original word into a near-synonym by displaying the near-synonym by referring to a near-synonym dictionary (S1). Then the device fetches the original word (S2) and another word in the sentence (S3) and retrieves another word which is in a cooccurrence relation with the original word by referring to a cooccurrence dictionary (S5). When cooccurrence data exist ('YES' in S6), the device retrieves the near- synonym of another word (S7). When the near-synonym exists ('YES' in S8), the device changes the other word to the near-synonym by displaying and selecting the near-synonym (S9).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sentence correction device.

[0002]

2. Description of the Related Art When proofreading a sentence using a sentence proofreading device that proofreads an input sentence, it is sometimes desired to replace a word in the sentence, for example, the word "seat" with a synonym.
Therefore, a synonym dictionary is prepared in the system in advance, and words having a relation between a specific word and a synonym, for example, “seat”,
In some cases, "chairs", "seats", and the like are displayed as replacement candidates, and the user is allowed to select a desired word and replace them. With a sentence proofreading device equipped with such a synonym dictionary, there is no need to check the dictionary at hand or start a separate synonym dictionary separately to perform a search, so that the sentence proofreading can be performed smoothly. Some Japanese sentences have a close relationship between words. For example, in the case of "Utsusu to seat", "Utsusu to photograph", and "Utsusu to movie", even if the pronunciation is the same "Utsusu", the meanings are different, and the kanji used for these are "Transfer seat" and " It can be used as "take a picture" or "show a movie". In addition, if you refer to “Atori Shukan”, “weekly”, “weekly”, “customs”, etc.
And "Atori Week". Such a specific word and a word closely related to it are said to have a co-occurrence relationship, and a combination of words having such a co-occurrence relationship is stored as a co-occurrence dictionary, and the kana-kanji conversion In some cases, accurate kana-kanji conversion can be performed by using this function. When the word is converted to a synonym during the proofreading of the sentence, for example, in the sentence "Transfer the seat.", If "Seat" is replaced by "Seat", the meaning is also understood as "Transfer the seat."
When the “seat” of “transfer seats” in Japanese is replaced with the Chinese word “seat”, “transfer”, which is closely related to “seat”, is converted to the Chinese word “move” and “ In some cases, the sentence "Move your seat."

[0003]

However, a plurality of words having such a co-occurrence relationship may be scattered in a sentence, and when "seat" is changed to "seat", a plurality of words may be located apart from each other. It is cumbersome to find "move" in the above and change it to "move", which has a problem that a burden is imposed on the proofreader and the efficiency of the proofreading operation is reduced. further,
In addition, there is a problem that the operator may overlook this and forget to change it to “move”, which breaks the balance as a sentence and lowers the quality of the proofreading work.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problem. When a predetermined word is changed to a synonym, the correction of a word co-occurring with this word is prevented, and the efficiency of the proofreading operation is improved. An object of the present invention is to provide a sentence proofreading device that can improve the quality of proofreading work.

Another object of the present invention is to provide a computer-readable recording medium on which a sentence correction processing program for causing a computer to execute such a sentence correction processing is recorded.

[0006]

In order to achieve this object, a sentence proofreading apparatus according to the first aspect of the present invention provides an input means for inputting Japanese sentences, a display means capable of displaying information, A morphological analysis dictionary that stores word notation and part-of-speech information, a synonym dictionary that stores synonyms for predetermined words, and a co-occurrence dictionary that stores co-occurrence words that are co-occurring with predetermined words. A morphological analysis unit that divides a Japanese sentence input by the input unit for each word based on the morphological analysis dictionary; and a synonym dictionary that searches for words by referring to the synonym dictionary and extracts synonyms of the word. A search means, and a synonym change which replaces an original word with a synonym selected by the input means, displaying a synonym extracted by the synonym dictionary search means for an arbitrary word on the display means. Means, when the original word replaced with the synonym is converted into a synonym, for another word in the sentence to which the original word belongs, co-occurrence of a word having a co-occurrence relationship with the original word A co-occurrence dictionary search unit for extracting a co-occurrence word by searching with reference to a dictionary, and extracting a synonym by referring to the synonym dictionary for the co-occurrence word extracted by the co-occurrence dictionary search unit, The apparatus further comprises a co-occurrence synonym conversion unit that displays the extracted synonyms on the display unit and replaces a co-occurrence word of the original word with a synonym selected by the input unit.

In the sentence proofreading apparatus according to this configuration, when an arbitrary word is to be changed to a synonym at the time of proofreading the sentence, the synonym to be changed is displayed by the synonym dictionary, so that only the displayed synonym is selected. Can be used to change the original word to a synonym, which not only facilitates proofreading work, but also automatically displays synonyms for co-occurring words that are closely related to the original word. Never forget to proofread co-occurrence words that are closely related to the change. In addition, since the change can be made only by selecting the displayed synonym, the proofreading operation is simplified. Therefore, the efficiency of the text proofreading operation can be improved, and the text proofreading operation can be performed in a well-balanced and high-quality proofreading operation.

According to a second aspect of the present invention, there is provided a computer-readable recording medium storing a text proofreading processing program.
A morphological analysis dictionary that stores notation of words and part of speech information,
A synonym dictionary that stores synonyms for a given word;
A co-occurrence dictionary for storing co-occurrence words having a co-occurrence relationship with a predetermined word, including an input unit for inputting a Japanese sentence, and a display unit capable of displaying information; A morphological analysis procedure for dividing a Japanese sentence input by the input means into words based on the morphological analysis dictionary, and synonyms for searching for words by referring to the synonym dictionary and extracting synonyms of the words A dictionary search procedure, and a synonym conversion procedure for displaying a synonym extracted for the arbitrary word by the synonym dictionary search procedure on the display unit and replacing an original word with a synonym selected by the input unit. When the original word replaced with the synonym is converted to a synonym, another word in the sentence to which the original word belongs, a word having a co-occurrence relationship with the original word is A co-occurrence dictionary search procedure for extracting co-occurrence words by performing a search with reference to the co-occurrence dictionary, and a synonym by performing a search with reference to the synonym dictionary for the co-occurrence words extracted by the co-occurrence dictionary search procedure. And displaying the extracted synonyms on the display means, and performing a co-occurrence synonym conversion procedure of replacing the co-occurrence of the original word with the synonym selected by the input means. I do.

In a computer-readable recording medium on which a sentence proofreading program according to this configuration is recorded, when a general-purpose computer wants to change an arbitrary word into a synonym at the time of proofreading a sentence, a synonym to be changed by a synonym dictionary is used. You can change the original word to a synonym simply by selecting it and selecting the displayed synonym, which not only facilitates the proofreading work, but also synonyms for co-occurrences that are closely related to the original word. Since a procedure for automatically displaying the words can be executed, the user does not forget to correct the co-occurred words that are closely related to the change of the original words. In addition, since the change can be made only by selecting the displayed synonym, the proofreading operation is simplified. Therefore, the efficiency of the text proofreading operation can be improved, and the text proofreading operation can be performed in a well-balanced and high-quality proofreading operation.

It exchanges data between the RAM 7 and the ROM 8, and is composed of an address bus, a data bus and the like.

The CPU 6 is a central processing unit that calculates data from the ROM 8, the RAM 7, and the interface 4 based on each program stored in the ROM 8. In the present embodiment, processing is executed based on each program,
Functions as each means.

The RAM 7 is a volatile memory that is freely readable and writable, and temporarily stores input text data and data necessary for the operation of the CPU 6. Input text storage area 71,
Various storage areas are provided, including a morphological analysis result storage area 72, a work area 73, an output data storage area 74, and an original word storage area 75.

The input text storage area 71 is a storage area for storing text data input from the input device 2 for later processing. The data is read out to the work area 73 and processed as necessary.

The morphological analysis result storage area 72 stores the result of morphological analysis of a Japanese sentence composed of input text data with reference to a morphological analysis dictionary 81 described later by the morphological analysis program 85. This is a storage area. FIG. 6 is a diagram schematically showing a part of the storage contents of the morphological analysis result stored in the morphological analysis result storage area 72. When the input sentence is morphologically analyzed, a character string that matches the word stored in the morphological analysis dictionary 81 is recognized as a word, and the “notation” data of the word and the character string at the head of the word are used as the head of the sentence. The data of "position" indicating the number of the character from the beginning, the data of "length" indicating the character string of the word, and the morphological analysis dictionary 81

It provides data necessary for searching for words that have a co-occurrence relationship.

The ROM 8 is a read-only non-volatile memory, and is a dictionary unit 8 for storing dictionaries necessary for the sentence proofreading process.
a, and a program unit 8b storing a program necessary for the sentence proofreading process and a control program for controlling the entire sentence proofreading apparatus. The dictionary unit 8a stores a morphological analysis dictionary 81, a synonym dictionary 82, and a co-occurrence dictionary 83. The program section 8b stores a synonym conversion program 84, a morphological analysis program 85, a synonym dictionary search program 86, a co-occurrence synonym conversion program 87, a co-occurrence dictionary search program 88, and a control program 89.

FIG. 5 is a diagram schematically showing a part of the storage contents of the morphological analysis dictionary 81. Morphological analysis dictionary 81
Stores a word notation 81a and a part of speech, inflected form, connection information, and other information 81b indicating the attribute of the word in association with the word of the notation.

FIG. 7 is a diagram schematically showing a part of the storage contents of the synonym dictionary 82. The synonym dictionary 82 stores word readings 82a and notations 82b in pairs, and stores synonyms having similar meanings in a group and associated with each other. In addition, the word is stored including not only the stem but also the part to be used so that it is displayed in a closed form because it is used.

FIG. 8 is a diagram schematically showing a part of the storage contents of the co-occurrence dictionary 83. The co-occurrence dictionary 83 is a dictionary that stores words having a co-occurrence relation in association with each other. A word having a specific relationship, for example, the verb “Utsusu” when “A is Utsusu” as in the above “Transfer a seat”, “Take a picture (take a picture)”, or “Show a movie” is ,
The notation is determined based on the presence of a specific noun corresponding to "A" and the presence of a particle "o" indicating the case of a phrase. Words having such a special relationship are said to have a co-occurrence relationship, and in the present application, another word that has a co-occurrence relationship with one word, such as "verb utus" for "noun A", is co-occurred. I will call it a word. Even if a co-occurrence word exists, if the particle "wo" does not exist and instead the particle "ga" is attached to the noun A, the case of the phrase is different and the co-occurrence relationship is not established. In the sentence "Shift your seat."
When searching for a co-occurrence relationship, it is also necessary to confirm the existence of the particle "wo". Therefore, as shown in FIG. 8, for example, <cough: seat>, <o>, and <depression: move> are stored in the co-occurrence dictionary 83 in association with each other as conditions for establishing a co-occurrence relationship.

The co-occurrence dictionary search program 88 is a program for referring to the co-occurrence dictionary 83 and searching for a word having a co-occurrence relation with an arbitrary word in the text. For example,
When searching for a word that has a co-occurrence relationship with the word “seat” in the sentence “move the seat.”, First, the sentence “move the seat.” ] Into words, stems, and inflections. First, the word "seat" is sequentially searched in the co-occurrence dictionary. When the word "seat" is found, next, the presence of the word stored in association with the word is searched in the text. Here, as conditions for establishing the co-occurrence relationship,
In addition to "seat", "to" and "to move" are necessary. Therefore, it searches for "" in the text. Here, since "" is present in the text, "transfer" is continuously searched for and "transfer" is found, so that a co-occurrence relationship of "seat" and "transfer" is established. The co-occurrence relation is good for independent words, and the adjunct particle "wo" is not called a co-occurrence word here. There are many other well-known rules in order to improve the accuracy of the search, but they will not be described in detail here for simplicity.

The synonym conversion program 84 searches the synonym dictionary 82 for an arbitrary original word using the synonym dictionary search program 86, displays the synonyms found as a result of the search as conversion candidates of the original word, and operates the operator. Is a program for converting any of the synonyms and the original word displayed by.

The synonym dictionary search program 86 is a program for searching the synonym dictionary 82 as shown in FIG. 7 for an arbitrary original word and extracting synonyms belonging to a group matching the original word. For example, if a search is made for “move”, as shown in FIG. 7, “move”, “migrate”, and “move” are grouped and stored in a group to which “move” belongs. "Move", "migrate", and "move" are extracted as synonyms.

The co-occurrence synonym conversion program 87 searches the synonym dictionary 82 for the co-occurrence word using the synonym dictionary search program 86 when the co-occurrence word co-occurring with the original word is in the same sentence. This is a program for displaying a synonym found as a result of the search as a co-occurrence conversion candidate, and converting any synonym and co-occurrence displayed by an operator's operation. The configuration is substantially the same as that of the synonym conversion program 84, but is partially different such that the word in the original word storage area 75 is not updated. Details will be described in the description of the flowchart.

The morphological analysis program 85 extracts the input sentence as a word by referring to the morphological analysis dictionary 81, and simultaneously adds the additional information added to the extracted word to the morphological This is a program extracted from the analysis dictionary 81 and stored in the morphological analysis result storage area 72.

The control program 89 is a program for controlling the entire sentence correction device 1. For example, execution of each of the programs 84 to 88, power management, input from the input device 2, output to the display device 3, external storage device 9 via the interface 4, and input / output of the communication line 10 are controlled. Then, the process of the sentence proofreading device 1 is executed. In the present embodiment, each program 84 to 89 and each dictionary 81 to 83 are described as the dedicated machine stored in the ROM 8 in the sentence proofreading apparatus 1. However, the sentence proofreading apparatus of the present invention is a general-purpose computer. , Each program 84 to 89 and each dictionary 81
To 83 can be installed and executed in an external storage device such as a hard disk. In this case, the control program 89 is an OS of a general-purpose computer.
(OperatingSystem) may execute some functions of the control program 89.

The external storage device 9 includes a hard disk drive, a floppy disk drive, a CD-ROM drive, and a DVD drive, and records information on a computer-readable recording medium such as a floppy disk, a hard disk, a CD-ROM, and a DVD. Alternatively, the information can be read. Further, as described above, each program 84 to 89 and each dictionary 81
To 83 can be installed in the external storage device 9 to execute the sentence proofreading process. In this case, a floppy disk, hard disk, CD-ROM, DV, or the like on which the programs 84 to 89 and the dictionaries 81 to 83 are recorded.
D or a semiconductor memory or the like corresponds to a computer-readable recording medium on which a sentence proofreading processing program is recorded.

The communication line 10 is configured as an information transmission medium capable of exchanging information with a computer via the interface 4. The information transmission medium is provided with a computer network system (LAN (Local Area Network) for propagating and supplying program information as a carrier wave.
aNetwork), WAN such as the Internet (WideAreaNetw)
ork), a communication medium (optical fiber, a wireless line, etc.) in a wireless communication network, etc., etc. Each of the programs 84 to 89 and the dictionaries 81 to 83 which constitute a sentence proofreading processing program by such an information transmission medium are stored. It is also possible to execute the sentence proofreading process by transmitting.

In this embodiment, each of the programs 84 to 89 constituting the sentence proofreading processing program and each dictionary 8
1 to 83 have independent configurations for the sake of convenience of explanation, but it goes without saying that these programs may be configured as an integrated configuration. In short, it is only necessary that a configuration that fulfills the functions of these programs exists in some form.

Next, the procedure of the sentence proofreading process in the sentence proofreading apparatus 1 according to the embodiment of the present invention will be described with reference to a flowchart.

FIG. 2 is a flowchart showing the entire flow of the processing procedure of the sentence proofreading program. here,
It is assumed that a sentence stored as text data in the external storage device 9 is corrected. The power of the sentence correction device 1 is turned on, and the control program 89 is started. Here, prior to the sentence proofreading process, the sentence proofreading data stored in the external storage device 9 is sent to the sentence input key from the keyboard, the input file is selected by the selection key, and the execution key is pressed. Thus, a reading process is performed. Then, predetermined text data from the hard disk of the external storage device 9 is stored in the input text storage area 71 via the interface 4. Since a plurality of sentences can be read into the input text storage area 71, the read sentences are displayed on the screen of the display device 3 in units of one sentence using a next sentence key, a previous sentence key, or the like.

FIG. 9 is a diagram showing a display screen of the display device 3 schematically showing a state in which a sentence to be sentence correction is displayed. As shown in FIG. 9, when the reading of the text is completed, a text to be corrected is displayed on the screen. The operator presses the next sentence key and the previous sentence key to change the sentence displayed on the display screen, and performs the proofreading operation in units of one sentence.

Here, in the explanation of the flow chart, as an example, it is assumed that the proofreading work of the sentence "Please move the seat there" shown in FIG. 9 is performed. When the text to be corrected is displayed, move the cursor to the word to be corrected in the text and press the synonym conversion key. In the example of FIG. 9, "seat"
It is assumed that the cursor is located at the portion and the synonym conversion key is pressed in this state. When the synonym conversion key is pressed, the sentence proofreading process starts. When the sentence proofreading process is started, the procedure of the synonym conversion process (step 1 (hereinafter, step is abbreviated as S)) of the flowchart shown in FIG.

FIG. 3 is a flowchart for explaining in detail the procedure of the synonym conversion process (S1) in FIG. When the synonym conversion process (S1) is started, the sentence displayed on the display device 3 is subjected to morphological analysis of one sentence with a cursor (S11). Here, the configuration is such that one sentence is displayed at a time, but a configuration may be employed in which a plurality of sentences are displayed. In this case, the sentence where the cursor is located is set as a processing target.

FIG. 4 is a flowchart for explaining in detail the procedure of the morphological analysis (S11) of one sentence in FIG. The procedure of the morphological analysis of one sentence (S11) will be described in detail with reference to this flowchart. The morphological analysis means that a sentence composed of a plurality of character strings is sequentially cut out from the beginning of a sentence while referring to the morphological analysis dictionary 81, and at that time, necessary information is extracted from the morphological analysis dictionary 81 to perform morphological analysis. This is the process of storing the result.

Processing for morphological analysis of one sentence (FIG. 3: S11)
Is started (FIG. 4: start), first, a word search (S11)
1) is performed. Word search is performed based on the longest match method. First, if the number of characters of the longest word stored in the morphological analysis dictionary 81, for example, it is actually longer, but is assumed to be 5 characters for explanation here, a character string of 5 characters is cut out from the beginning of the sentence, and this 5 characters Is searched for the same character string with reference to the morphological analysis dictionary 81. In the example of FIG. 9, a character string “there is a seat” is cut out, and the character string is searched for while seeing the matching with the word notation 81 a of the morphological analysis dictionary 81 shown in FIG. 5.
Then, since the word "that seat" is not found, the number of characters is reduced by one character to a four-character string, and the matching between the character string "that seat" and the word notation in the morphological analysis dictionary 81 is performed. Search while looking. In this way, the search is repeated until words are found sequentially while reducing the number of character strings to be cut out one by one. In this example, a character string obtained by cutting out two characters “that” matches the notation of the word “that” in the morphological analysis dictionary 81 as shown in FIG.

Similarly, the search is sequentially performed. If a word that matches the extracted character string cannot be searched (S112: NO), unknown word processing (S116) is performed.
The character string that could not be searched is temporarily stored in an unknown word storage area (not shown) of the work area 73 as a character string constituting an unknown word. Next, the processing position is moved (S117), and if it is not the end of the character string (S118:
NO), similarly, the word search (S111) is repeated until the new word search succeeds (S112: YES), and the character string is added and stored in the unknown word storage area. When succeeded (S112: YES)
, The character string up to the character before the character string is determined and recognized as one unknown word.

Next, the word search (S111) succeeds (S111).
112: YES), the additional information is read from the morphological analysis dictionary 81 for the character string cut out as a word, and the connection relationship with the immediately preceding word is tested (S113). Here, whether the connection is grammatically possible is mainly tested from the part of speech information, and if it is determined that the connection is OK (S114: Y
ES), the position of the first character of the character string from the beginning of the character string and the number of characters are stored in the morphological analysis result storage area 72 together with the additional information of the found word (S115). In this case, verbs and other verbs can be separated into stems and conjugations, so that they are separated into stems and conjugations and stored together with additional information for easy processing. Then, it moves to the processing position of the next character string (S117), and if it is not the end of the character string (S118: NO), the next word search (S111).
Move to

For example, in the case of the word "that",
As shown in FIG. 6, the part of speech information “adnominal” is added to the morphological analysis dictionary 81 as the part of speech. In this case, there is no immediately preceding word, but unlike particles, etc., even if there is no immediately preceding word, the connection relation is OK because it is grammatically correct. If the word is “seat”, the part-of-speech information of “noun” is added. If the immediately preceding word is “adnominal” of “that”, even if the noun continues here, it is grammatically correct. Since it is determined, the connection is OK. Therefore, if it is “that”, the morphological analysis result storage area 72 shown in FIG.
As shown in the table, information that the notation of the word “that”, the “0” character from the beginning of the sentence, the character string length is “2” characters, and the part of speech is “adnominal” is stored. Also,
As for “seat”, information that the notation of the word “seat” is “2” characters from the beginning of the sentence, the character string length is “1” characters, and the part of speech is “noun” is stored.

If the connection cannot be grammatically connected (S114: NO), the cut-out character string has been successfully searched, but is determined to be an unknown word different from the word in the morphological analysis dictionary 81, and the character string is re-entered. A word search (S111) is performed with the sequence reduced by one character, and the morphological analysis dictionary 81
Is not the character string (S112: NO), it is processed by unknown word processing (S116). If the word is determined as an unknown word, it is stored as an unknown word in the morphological analysis result storage area 72 in the same manner as the word successfully searched in S116.

As described above, words are sequentially cut out from the beginning of the sentence and processed. If there is no character string to be processed at the end of the character string (S118: YES), the processing of morphological analysis (S11) of one sentence in FIG. 3 ends. Then, the process proceeds to S12 in FIG. 3 (return).

In the example of the sentence "Please move that seat to that place.", The result of the morphological analysis results in the result shown in FIG. 6, and "their / seat / to / to / to / toward / to / to / Please ".

Returning to the flowchart of FIG. 3, the description will be continued. The word at the cursor position is identified in the input character string divided into words by the morphological analysis of one sentence with the cursor (S11) (S12). Then, the word is searched with reference to the synonym dictionary 82. By synonym dictionary search (S13), the word is converted to synonym dictionary 8
2 (S14: YES), a synonym of the word is displayed on the display screen of the display device 3 (S15).

In the example sentence, in the input character string which is cut into words such as “that / seat / to / to / to / to / to / to / please” by morphological analysis of one sentence with the cursor (S11), It is identified that the word at the cursor position is the word "seat" (S12). And "seat"
The search for the word is performed with reference to the synonym dictionary 82 (S13). In this example, the word "seat"
Since the synonym dictionary 82 exists as shown in FIG.
4: YES), its synonyms "chair", "seat",
“Sheet” is displayed on the display screen of the display device 3 (S1).
5). Here, FIG. 10 is a schematic diagram illustrating a synonym of the original word displayed on the display screen of the display device 3. In this example, as shown in FIG. 10, "chair", "seat", and "seat" are displayed below the word "seat", for example, in a pop-up window.

Next, a synonym displayed on the display screen of the display device 3 is selected by key input using the cursor key (S1).
6) If the synonym selection key is pressed (S17: YE)
S), the display of the original word initially displayed at the position where the cursor is located is replaced with the selected synonym (S20).
At this time, the storage of the original word storage area 75 is cleared,
The new original word is stored, the synonym conversion process (S1) in FIG. 2 ends, and the process proceeds to the original word extraction process of S2 (return).

Until the synonym selection key is pressed in S17 (S17: NO), if the cancel key is pressed (S18: YES), the synonym conversion processing (FIG. 2: S
The process of 1) is completed (return). If the cancel key is not pressed (S18: NO), other processing is performed in accordance with the command, for example, moving the cursor to shift to the proofreading of the next word, or ending the proofreading processing itself by the end key. Then, the calibration result is stored in the external storage device 9 or, if a printer (not shown) is connected, a printing process is performed (S19).

FIG. 10 is a schematic diagram showing synonyms of the original word displayed on the display screen of the display device 3. In the illustrated example, as shown in FIG. 10, the cursor is input by a cursor key from “chair”, “seat”, and “seat” (S15) displayed as a pull-down window below the word “seat”. To "Seat" (S1
6) If the synonym selection key is pressed (S17: YE)
S), the word "seat" in the sentence is converted to the word "seat" (S20), and the display of the pull-down window is terminated. At this time, the storage of the original word storage area 75 is cleared, and the "seat" serving as the original word is stored (S2).
0).

Here, returning to the flowchart of FIG. 2, the description will be continued. When the synonym conversion processing (S1) is completed, the original word stored in the original word storage area 75 is called into the work area 73, the original word is extracted (S2), and the original word is used as a keyword, and the morphological analysis result storage area is used. 72
From the sentence divided into the words stored in (1), another word (hereinafter referred to as another word) in the sentence other than the original word is extracted one by one from the beginning of the sentence (S3). If the word is not the end (S4: NO), the original word and another word are
The co-occurrence dictionary 83 is searched for a co-occurrence relationship (S5). Here, if the co-occurrence data cannot be found and the extracted another word has no co-occurrence relationship with the original word (S6:
NO), the next different word is extracted (S3). If the word is not the end (S4: NO), co-occurrence data is similarly searched for the different word (S5). In this way, another word is sequentially extracted from the beginning of the sentence, and co-occurrence data is searched (S3, S4: NO, S5). If the search is successful and co-occurrence data is found (S6: YES), the other word is searched. Is searched for a synonym with reference to the synonym dictionary 82 (S7). If no synonym is found (S8: NO), the search is terminated, and the process proceeds to the next another word (S3). If a synonym is found in the search in S7 (S8: YES), a synonym display and selection process (S9) is performed.

In the illustrated example, when the synonym conversion processing (S1) is completed, the original word “seat” stored in the original word storage area 75 is called into the work area 73 (S1).
2), using this original word “seat” as a keyword, the sentence “that / seat / to / to / to / to / to / to / to / to which the word is divided into words stored in the morphological analysis result storage area 72 as shown in FIG. For "te / please", in order from the beginning of the sentence, words other than "seat""that","a","that","to","move","shi"
"T" and "Please" are taken out one by one (S3). If the word is not the end (S4: NO), whether or not the original word and another word have a co-occurrence relationship is searched with reference to the co-occurrence dictionary 83 as shown in FIG. 8 (S5). ). Here, for example, if “that”, the co-occurrence data cannot be found and the extracted another word has no co-occurrence relationship with the original word (S6:
(NO), the next different word "wo" is extracted (S3), and since the word is not the end (S4: NO), co-occurrence data is similarly searched for "wo" (S5). In this way, another word is sequentially extracted from the beginning of the sentence, and the co-occurrence data is searched (S3, S4: NO, S5). Therefore, the search succeeds (S6: YES). Note that, in the search, since the stem is searched for a word having inflection, if a synonym is searched for “move” by referring to the synonym dictionary 82 (S7), “move”, “migrate”, “move” Is found (S8:
YES), a synonym display and selection process (S9) is performed.

The synonym display and selection process (S9) is shown in FIG.
Synonymous display and selection processing of the original word shown in (S15 to S2)
This is substantially the same processing as in (0). FIG. 11 is a schematic diagram showing synonyms of co-occurrence words displayed on the display screen of the display device 3. In the synonym display and selection process (S9), as shown in FIG. 11, a synonym of another word that is a co-occurrence is found is displayed on the display screen of the display device 3, and key input is performed using the cursor keys of the display device 3. If there is, a synonym displayed on the display screen is selected, and if the synonym selection key is pressed, the display is replaced with a selected synonym from another word that is a co-occurrence word displayed at the position where the cursor is located. . S
When the synonym display and selection processing in 9 is completed, the processing shifts to the processing of the next another word (S3).

A synonym display and selection process (S9) will be described with reference to flowcharts S15 to S20 in FIG. When there is a synonym in S8 in FIG. 2 (FIG. 2: S8: YE
S) Similar to the processing of S15, a synonym of the word is displayed on the display screen of the display device 3.

In the illustrated example, the word “move” is
Since the synonym dictionary 82 exists as shown in FIG.
Similar to the processing of 5, the synonym “move”
“Move” and “Move” are displayed on the display screen of the display device 3. In this example, as shown in FIG. 11, "move", "move", and "move" are displayed in a window below the word "move".

Next, as in the process of S16, a key input is made with the cursor key to select a synonym displayed on the display screen of the display device 3, and the synonym selection key is pressed in the same manner as in the process of S17. In the same way as the processing, another word "move" that was initially displayed at the position of the cursor is replaced with the selected synonym "move", and the message "Please move that seat there." Is displayed, and the window is displayed. Will be erased. However, unlike the processing in S20, the storage of the original word storage area 75 is maintained as it is, and no new original word is stored. Then, the synonym display and selection process (S9) in FIG. 2 ends, and the process proceeds to the process of extracting the next different word in the sentence in S3.

Until the synonym selection key is pressed,
S18: If the cancel key is pressed in the same manner as the process of NO, the process of the synonym display and selection process (S9) ends. If the cancel key is not pressed in the same manner as in step S18: NO, other processing, for example, moving the cursor to move to the proofreading of the next word according to the command, or similar to the processing in step S19. The proofreading process itself is terminated by the key, the proofreading result is stored in the external storage device 9, or the printing process is performed if a printer (not shown) is connected.

Even if the processing of one different word having a co-occurrence relationship is completed, the same processing (S3 to S9) is repeated because the co-occurrence relationship is not limited to one word. Then, the process is terminated up to the last word of the sentence, and if there is no other word to be processed, the process is terminated as a word end (S4: YES) (end). In the example sentence, there is no other word having co-occurrence data, and thus the processing is terminated.

In the present embodiment, the morphological analysis program 85 causes the CPU 6 to execute the morphological analysis procedure of S11, and the CPU 6 that executes this procedure corresponds to the morphological analysis means of the present invention. The synonym dictionary search program 8
