Abstract

PURPOSE:To simplify the input processing of entry words to be used for retrieving synonyms by an operator by specifying the candidate of homonyms obtained as the result of the KANJI conversion. CONSTITUTION:The KANA (Japanese syllabary)/KANJI (chinese character) conversion is performed on the inputted KANA character strings. When the 1st candidate in the homonyms is selected, the character string of the 1st candidate is displayed on a display 5. When the 1st candidate is not the phrase which is required by the user, he can directs the switching of the homonym selection mode and the selected candidate of homonym from a keyboard 2. When detecting the direction of mode, a CPU 1 acquire the candidate of homonym by using a reference word dictionary and stores it in a same sound area 4-2 of a RAM 4. The user specifies the required homonym by using a direction key 2-2 and directs the decision on the homonym by using a decision key 2-4 for the CPU 1. The CPU 1 defines the character strings with KANA/KANJI mixed according to the direction of the decision.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character processing method for converting a kanji-converted kanji or kanji string into synonyms.

[0002]

2. Description of the Related Art Conventionally, a character processing device such as a front-end processor performs selection processing of synonyms in the following processing order. That is, the user inputs a kana character string from the keyboard and instructs the character processing device to perform kanji conversion. The character processing device performs kana-kanji conversion by a known method to create kana-mixed kanji (including one kanji). When there are a plurality of Kanji conversion candidates (referred to as homophones) having the same sound, the same phoneme is displayed on the display. The user sees the display of the homophones, selects a desired candidate, and designates a fixed homophone (kana-mixed kanji form). Next, the user instructs the character processing device to search for synonyms for the fixed kana-mixed kanji. In the character processing device, a character string (called a synonym) having the same meaning as the designated kanji character string is detected from the kanji dictionary inside the device and displayed on the display.

When there are a plurality of synonyms, the character processing device displays the synonym candidates to be selected on the display, and determines the synonyms by the user's selection.

[0004]

As described above, in order for the user to obtain a desired synonym, the user has to perform two kinds of selection processing, that is, selection of a homonym and selection of a synonym. However, the conventional character processing method has a problem that the keyboard operation is complicated and the document creation processing time becomes long.

Therefore, in view of the above points, the present invention provides a character processing method capable of simplifying a user's operation for obtaining synonyms.

[0006]

In order to achieve such an object, the invention of claim 1 is a kana-kanji conversion method, in which a homophone word candidate corresponding to a kana character string to be converted is displayed, and the displayed homophone word is displayed. In a character processing method for determining a kanji string after kana-kanji conversion by selecting a candidate, when a synonym candidate corresponding to the kana character string to be converted is displayed, a synonym search processing mode is set, and the synonym search processing mode is set. The homonym candidate corresponding to the kana character string is regarded as a phrase to be subjected to the synonym search, the homonym candidate of the display is alternatively designated, and the synonym corresponding to the designated homophone candidate is stored in the synonym dictionary. Characterized by searching from inside.

According to a second aspect of the present invention, the kana-kanji conversion in claim 1 is a process for converting kana-mixed kanji into kana-mixed kanji. When the homonym candidate is kana-mixed kanji, the kana-mixed kanji is searched for synonyms. It is characterized in that it is modified to the inflection form for.

The invention of claim 3 uses the synonym candidate obtained by the search for the synonym of claim 1 so that the same synonym as the kana mixed kanji included in the homonym candidate of claim 2 is obtained. The shape is corrected, and the corrected synonym candidates are displayed for confirmation.

The invention of claim 4 is characterized in that, every time the different displayed homophonic word candidates of claim 1 are designated, the synonym candidates corresponding to the designated homonym word are switched and displayed. .

According to the invention of claim 5, the synonym candidates obtained as a result of the search of claim 1 are displayed, the homonym candidate displayed or a specific candidate among the synonym candidates is designated, and the designated candidate is designated. Is defined as a word used in the created document.

[0011]

The present invention focuses on performing synonym retrieval when the user does not like the result of Kanji conversion during document creation, and that the process of selecting a homophone easily occurs in Kana-mixed Kanji conversion. . Claim 1
In the invention of (1), by specifying a homophone candidate obtained as a result of Kanji conversion, the operator's input process of the entry word (keyword) used for the synonym search is simplified.

According to the second aspect of the present invention, the homonym candidate can be modified into the inflectional form used for the synonym search, so that the inflectional form of the entry word described in the synonym dictionary can be made into one type.

The invention of claim 3 eliminates the operation of the synonym by the operator by automatically returning the synonym candidate inflection obtained as a result of the synonym search to the homonym candidate inflection.

According to the fourth aspect of the present invention, since the synonyms are displayed in association with the designation of the homonyms, the operator does not have to instruct execution of the synonym search each time.

According to the fifth aspect of the invention, when there is no desired phrase in the synonym candidates, the homonym candidate can be determined as the phrase used in the document.

Embodiments of the present invention will now be described in detail with reference to the drawings.

<< First Embodiment >> FIG. 1 shows a system configuration of a character processing apparatus to which the present invention is applied.

In FIG. 1, a CPU (central processing unit)
Reference numeral 1 executes main processing of the entire apparatus and character processing such as Kana-Kanji conversion and synonym conversion related to the present invention. Keyboard 2
Inputs various information by key operation. Input key 2-
Reference numeral 1 includes a kana character key used for document creation and a control key related to character processing, for example, a conversion key for instructing kana-kanji conversion. For example, a cursor key is used as the designation key 2-2 and is used when designating a homonym candidate or a synonym candidate on the display screen for selection.

The synonym display key 2-3 is a key for instructing to display a list of synonym candidates for the homophone candidate designated by the designating key 2-2 when the list of homonyms is displayed. By operating this key, the synonym search mode is set. Confirm key 2-4 is designated key 2-2
This is a key for instructing to confirm the candidate designated by.

ROM (Read Only Memory) 3 stores various fixed information. The program information 3-1 stored in the ROM 3 is a program executed by the CPU 1, and includes a synonym display / replacement processing program at the time of homophone conversion. The standard word dictionary 3-2 is dictionary information for kanji conversion that describes grammatical information for dividing kana mixed kanji corresponding to a kana character string (reading) into word units.

The synonym dictionary 3-3 is dictionary information in which synonyms corresponding to the headwords are described, and is used in the synonym conversion processing and the related display processing.

A RAM (random access memory) 4 stores various kinds of information to be processed by the CPU 1 in the following areas in association with the types of information.

The work area 4-1 stores general information used in the arithmetic processing of the CPU 1. The same-sound word area 4-2 stores the same-sound word information about a kanji string obtained by kana-kanji conversion.

The synonym area 4-3 stores synonym information obtained by the synonym conversion process. Display 5 is CP
Information supported from U1, for example, a character string input from the keyboard 2, kana-blended kanji after kanji conversion, or a plurality of homonyms and a plurality of synonyms candidates are displayed. Document information in the process of being created is stored in the other area of the RAM 4.

The Kanji conversion and synonym conversion processing executed in such a configuration will be described with reference to the flowchart of FIG. The flowchart of FIG. 2 shows a control procedure executed by the CPU 1.

The user operates the input keys 2-1 of the keyboard 2.
Is used to input a kana character string, for example, "Kikaiga" (S1). The CPU 1 performs kana-mixed kanji conversion on the input kana character string "kikaiga" (S2). If you get "Machine" as the first candidate in the homophone, this
The candidate character string is displayed on the display 5 (S2). If the first candidate is not the word desired by the user, the user instructs the homophone selection mode and the selection of the homophone selection from the keyboard 2, so when the CPU 1 detects this mode instruction, the CPU 1 uses the standard word dictionary. Is used to obtain a homophone word candidate and store it in the homophone word area 4-2 of the RAM 4. It also performs a process of displaying a list of homophone candidates.
By this process, the selection candidates such as “Opportunity”, “Machine”, and “Machine” in the above example are displayed on the display 5 as in the display (a) of FIG. 3 (S3 →
S4 → S5). The user designates a desired homophone using the designation key 2-2 (S6), and issues a confirmation instruction for the designated homophone to the CPU 1 using the confirm key 2-4. In response to the confirmation instruction (affirmative determination in S7), the CPU 1 determines the designated homophone as a character string containing kana-kanji used in the created document (S15).

On the other hand, when the list of homonym selection candidates is displayed as shown in the display (a) of FIG. 3 (S5), the user uses the designation key 2-2 to select a homonym word, for example, "opportunity". When the synonym display key 2-3 is operated after "ga" is designated (S6), the CPU 1 activates a synonym search process for the designated homonym candidate (S7 → S8).

Even when the synonym display keys 2-3 are operated in a state where the homonym selection mode is not set, that is, only the first selection candidates of the homonym are displayed, the first selection candidate is designated. The synonym search process is started as the selected homonym (S3 → S7 → S8). CPU1
Reads and executes the synonym search processing program from the program area 3-1 of the ROM 3. Although the synonym search process itself is well known, it will be briefly described because it is related to the present invention. In other words, the designated kana-mixed kanji "Chiba"
The grammatical analysis information obtained in the grammatical analysis process for converting Kanji is temporarily stored in the work area 4-1 of the RAM 4 (S9). In the case of this example, the grammar analysis result is a noun (opportunity) + case particle (ga). Next, the CPU 1 corrects "Ochaniga" to an independent word used as a headword of the synonym dictionary and its inflection. In the case of this example, since the independent word is a noun, the Chinese character string “Opportunity” is the headword for the search. Therefore, a synonym corresponding to "opportunity" is searched from the synonym dictionary as usual (S10).

As a result, as the synonyms corresponding to "opportunity", "time", "time luck", "period", and "tide time" are obtained as search results, that is, synonym selection candidates. RAM4
The search result of is stored in the synonym area 4-3, and then the case particle “ga” is added to these selection candidates based on the grammatical analysis information. After this, the CPU 1 displays the display 5
As shown in the display (b) of Fig. 3, "Time", "Time Luck",
"Time" and "tide time" are displayed (S11 → S1
2).

The user sees this display and specifies the key 2-2.
Use, to specify, for example, “tide time”, and press the Enter key 2
Operate -3. As a result, the CPU 1 determines the designated synonym candidate as a character string used in the document, and replaces the display on the display screen with the confirmed character string as shown in the display (c) of FIG. 3 (S13 → S14). If a desired synonym cannot be found among the synonym candidates displayed on the display screen, the user uses the mode cancel key or the like to operate the CPU 1
When notifying that, the CPU 1 returns the execution procedure to S5 and displays the homonym selection screen. As a result, CP
The processing mode of U1 is also switched from the synonym conversion mode to the homophone selection mode.

The following example can be implemented as an application form of the first embodiment.

1) The selection screens for the homonym candidate and the synonym candidate in FIG. 3 can be configured as shown in FIGS. 4 and 5. In the display (a) of FIG. 4, X is a first candidate for a homophone and Y is a list of homophone candidates. The display (b) of FIG. 4 shows a state where the designated phrase in the list of homophones is changed from the state of the display (a) of FIG. In the display (a) and display (b) of FIG. 5, a list of synonym candidates corresponding to the designated homonym candidate is displayed, and a specific candidate in this list is designated as a confirmation target. Indicates. FIG. 6 shows a state in which the synonym candidates designated in the display (b) of FIG. 5 are confirmed and the display is switched.

2) In the present embodiment, the instruction information for the CPU 1 is input from the keyboard 2, but an input device such as a mouse, a joystick, a lock ball, or a touch panel can be used.

3) In order to correct a homonym word candidate to a headword used for synonym search, a correspondence relation between various inflectional forms and inflectional forms for headwords is determined in advance, and C is based on this correspondence relation.
The correction process is executed by PU1. Also. When the variation of the use of the headword is described in the synonym dictionary, the homonym candidate can be used as the headword as it is, but in this case, the capacity of the synonym dictionary becomes large.

<< Second Embodiment >> The first embodiment is an example of switching to the synonym conversion mode in the middle of the kanji conversion mode, but the synonym candidates can be displayed in synchronization with the selection and designation of the homonym. A second embodiment will be described.

The circuit configuration of the second embodiment is shown in FIG. The same parts as those in the circuit configuration of the first embodiment shown in FIG. 1 are designated by the same reference numerals and detailed description thereof will be omitted.

The keyboard 2 is newly provided with a synonym designation switching key 2-5 and a synonym interlocking switching key 2-6. The synonym designation switching key 2-5 is a key for designating whether the phrase designated by the designation key 2-2 is a homophone selection candidate or a synonym selection candidate. Synonym interlocking switching key 2
-6 is a key for switching between a mode in which a list of synonyms is displayed in synchronization with the designation of a homonym candidate and a mode in which it is not synchronized.

FIG. 8 shows the character processing procedure executed by the CPU 1 in such a configuration, and the operation of the character processing apparatus will be described in accordance with this character processing procedure.

In the character processing procedure of FIG. 8, the same parts as those of the character processing procedure of FIG. 2 of the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

In the kana-kanji (blended) conversion mode, the user says "let's take the Otorioko" and the keyboard 2
Input from (S1). The CPU 1 executes kana-mixed kanji conversion (S2). When the undetermined homonym is the phrase corresponding to “Toroto”, a list of homonym candidates is displayed below the first candidate as shown in display (a) of FIG. 10. As in the case of the first embodiment, the same key word is reproduced by using the designation key 2-2.
When the user operates the synonym display key 2-3 after designating as shown in 0 (b), the synonym conversion mode is set (S3 to S8). After acquiring the grammatical analysis information about the designated homonym, the CPU 1 creates a synonym conversion entry word (take) from the homonym candidate and executes a synonym conversion process (S9 → S10).

As a result, when a synonym corresponding to "take" is obtained, a character string is attached to the synonym candidate based on the grammar analysis information so that the synonym is the same as the designated homonym candidate. Since "Tokuroto" is a five-stage verb preform (collecting) + auxiliary verb (u) + connecting particle (and), the CPU 1 corrects synonym candidates in the search result so as to correspond to this grammatical form (inflectional form). . As a result, "Let's collect", "Let's adopt", "Let's vote", etc. are created.
It is displayed as in (a) (S10). The detailed procedure of S10 is shown in FIG. 9 for reference. Here, when the user operates the synonym interlocking switching key 2-6, a synonym candidate corresponding to the homonym candidate designated for each designation of the homonym candidate of the designation key 2-2 is detected by the synonym search processing similar to the above. And displayed on the display screen (see displays (a) and (b) in FIG. 11, S22 → S23).

The user designates a word to be determined from the names of the homonym candidate and the synonym candidate displayed in this way. To specify a homonym candidate, the user specifies key 2
-2 to specify a homonym candidate, and then enter key 2-
When CPU 4 is operated, CPU 1 identifies that the specified phrase is a homophone, and reads the specified homophone candidate from homophone area 4-2 of RAM 4 and replaces it with a homophone candidate in the document information (S21). → S30 → S24 → S25).

On the other hand, when confirming a synonym candidate, the CPU 1 is informed of the designation of the synonym using the synonym designation switching key 2-5, and the next designation key 2-2 and the confirmation key 2-4 are operated to confirm the synonym. Notify the CPU 1 of the candidates. Therefore, the CPU 1 reads out the designated synonym candidate from the synonym area 4-3 of the RAM 4 and replaces it with the homonym candidate in the document information (S20 → S40 → S24 → S25). For example, when the synonym candidate “let's catch” is specified as shown in (a) of FIG. 12, the document information is displayed as “let's catch a bird of large birds” to “Let's catch a large bird of birds” as shown in (b) of FIG. And "."

The following example can be given as an application form of the second embodiment.

1) In this embodiment, the synonym designation key 2-5 of the keyboard 2 is used to notify the CPU 1 of the synonym designation mode. However, the CPU 1 side determines the cursor position of the designation key 2-2 and the designation candidate is the synonym. It is possible to distinguish between homophones and homophones.

2) The synonym conversion process of this embodiment may be performed every time a homophone occurs, or may be performed collectively for a plurality of homophones.

[0047]

As described above, according to the present invention,
A synonym search can be executed during the homophone determination process, and it is not necessary to perform character input and kanji conversion processing only for the synonym search. Therefore, the time required for the synonym search process can be shortened.
