Abstract

PURPOSE:To lighten the burden imposed on a user and to unify the expression of sentences by providing a means deciding the display of homonyms and deciding whether or not homonyms are displayed based on synonym information and expression one. CONSTITUTION:When a KANA (Japanese syllabary) string (word) is inputted by an input device 1, it is transmitted to a dictionary retrieval part 2. It retrieves words corresponding to said KANA string from a word dictionary 8, provisionally stores them in a dictionary buffer 4, decides plural candidates, transmits them to a display part 3 from the buffer 4, and displays them on the screen of a display device 5. The user selects one among plural candidates displayed on the screen. A synonym marker rewrite part 7 and a display marker rewrite part 7 rewrite a synonym marker and a display one in the dictionary 8. Thus the display of synonyms with different expressions are reduced to one.

Description

[Detailed Description of the Invention] Technical Field The present invention relates to a kana-kanji conversion device, and in particular to a kana-kanji conversion device that facilitates word selection from a plurality of conversion candidates displayed on a display device and is suitable for creating unified sentences. This relates to a kanji conversion device.

BACKGROUND ART Conventionally, in a kana-kanji conversion device used in a Japanese word processor or the like, a word dictionary storing words and grammar processing are required in order to convert a sentence input in kana writing into a sentence containing kanji and kana. Each word in this word dictionary is (1)
It consists of word reading information, (11) grammatical information such as word part of speech and conjugation, (iii) kanji information when written with a mixture of kanji and kana, and (iv) word frequency information for each user. The parts of speech of words include nouns, Su-modal nouns, 5-stage conjugated verbs, upper 1-stage/lower 1-stage conjugated verbs, power change/su variation system,
adjective.

Adjective verbs, IIJ words, adjunctive words, interjections, auxiliary verbs, particles.

A distinction is made between prefixes and suffixes. Furthermore, in Japanese, there are no clearly established rules regarding okurigana, and there are a wide variety of ways to use them depending on the person. For example, when writing the word ``karidasu'' in kanji, one person may write it as ``borrow'' and another may write ``borrow''. Therefore, when configuring a word dictionary, multiple okigana are allowed for kanji information, and for the reading ``karidasu'', the kanji information can be expressed in two ways: ``borrow'' and ``borrow''.
Write down one. By filling in this way, the beneficiary can:
You can select the okurigana you want to use.

When converting kana to kanji using a word dictionary configured in this way, the number of candidates must be increased in order to select all homophones registered in the word dictionary for words entered in kana characters using a keyboard, etc. Therefore, there is a problem in that the burden on the user is large when selecting words to be displayed on the screen of the display device.

This is because the number of words displayed on one display device is usually fixed, so when the number of word candidates increases for one kana character input, it takes more time to look up the words displayed on one screen. This increases the burden on the user and causes fatigue. Also, even if the device has a learning function,
Since it is unclear which notation was previously selected for the meaning, the uniformity of the notation may be impaired. This means that, for example, if the previous notation ``borrow'' was selected, but the first notation ``borrow J'' was selected, the consistency of the notation would be lost if all three sentences were combined. .

Purpose The purpose of the present invention is to improve such conventional problems, and to provide a kana-kanji conversion device that displays homophones as candidates from a word dictionary, which makes it easy to select homophones and reduces the burden on the operator. An object of the present invention is to provide a kana-kanji conversion device that can achieve uniformity in notation of sentences.

Configuration In order to achieve the above object, the kana-kanji conversion device of the present invention includes a word dictionary storing at least the pronunciations of words and notations corresponding to the pronunciations, a dictionary search means for searching the word dictionary, and the dictionary. In a kana-kanji conversion device having means for displaying homophones as conversion candidates based on the search results by the search means, means is provided for determining the display of the homophones, and the display determining means selects the plurality of words included in the word dictionary. Whether or not to display the above-mentioned homophone is determined based on synonymous information indicating whether or not the above-mentioned notations have a synonymous relationship, and representative notation information indicating which notation among the notations in the synonymous relationship is the representative notation. It is characterized in that the synonymous information and representative notation information can be determined and further changed by means of rewriting the synonymous information and representative notation information.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

First, the present invention will be explained in detail.

In a kana-kanji conversion device that searches and displays words from a word dictionary when inputting kana characters, all homonyms (homonyms and homophones) were displayed as candidates in the word search, making it difficult for the user to select. It took time. but,
In the present invention, a synonym marker is provided to distinguish between a homophone synonym and a homophone, and a display marker is provided to distinguish between a homophone and a homophone.
For items with multiple Japanese okigana, please write multiple notations.
This is intended to reduce the burden on the user by displaying only those words first, making it easier to select words, and by allowing the user to rewrite the words that are displayed first.

FIG. 1 is a schematic configuration diagram of a kana-kanji conversion device showing an embodiment of the present invention. This means that a kana string is input,
This is to explain the process of performing a dictionary search from a word dictionary, displaying a plurality of candidate words, and allowing the user to select a desired word from the displayed plurality of candidates.

Further, since the other configurations are the same as before, their explanation will be omitted, and detailed kana-kanji conversion control not described in this embodiment can be realized using conventional existing technology.

In FIG. 1, 1 is an input device for inputting a kana character string;
2 is a dictionary search unit that searches the word dictionary 8 for words corresponding to the input kana character strings; 3 is a dictionary search unit that searches a plurality of homophones searched by the dictionary search unit 2 based on synonym markers and display markers; 4 is a dictionary buffer that temporarily stores words transferred from the word dictionary 8; 5 is a display device (for example, a CRT display) that displays words containing multiple homophones on the screen under the control of the display unit 3; ), 6 is a synonym marker rewriting unit provided according to the present invention, 7 is a display marker rewriting unit provided according to the present invention, and 8 is a word dictionary in which information such as words is stored.

The simple operation of the kana-kanji conversion device shown in FIG. 1 will be explained below.

When a kana character string (word) is input through the input device 1,
It is sent to the dictionary search section 2. The dictionary search unit 2 searches the word dictionary 8 for a word corresponding to the input kana character string (word) sent, temporarily stores it in the dictionary buffer 4, determines a plurality of candidates, and displays the word from the dictionary buffer 4 on the display unit 3 &' - feed and display on the screen of the display device 5. The user will select one from the multiple candidates displayed on the screen. Furthermore, the synonymous marker rewriting unit 61 and the display marker rewriting unit 7 rewrite synonymous markers in the word dictionary 8 or rewrite display markers. As a result, the number of different spellings for homophones and synonyms can be reduced to one.

FIG. 2 is a schematic diagram of the word dictionary 8 according to the present invention. Here, grammatical information such as the word's part of speech and conjugation, and word frequency information by user are the same as before, so they are omitted and the words are written in two readings.

7. Only display markers and synonymous markers provided according to the present invention are shown.

As shown in FIG. 2, this word dictionary has a dictionary that has synonym markers and display markers in addition to pronunciations and notations. This synonymous marker is valid only for items with the same pronunciation, and items with the same value have the same meaning.

However, ``0'''' is an exception and indicates that there are no synonyms in the same reading.In the example in Figure 2, ``borrow''
and "borrow" are a pair of synonyms.

“Karidashi” and “huntout” are also another set of synonyms. Synonymous markers are 0, 1, 2. Let's assume here that we take the number... The display marker is a flag that indicates whether or not to display the word on the word selection screen.
indicates that it is not displayed, and It I II indicates that it is displayed. If the synonymous marker is II OII, the display marker is always It I II. Synonymous marker is II O1
If not ', set to take either II OII or '1''.

FIG. 3 is a diagram showing an example of a first word selection display according to the present invention. This is an example of a conversion candidate that is first displayed on the word selection screen of the display device 5 for the kana character ``Karidasu'' (8).

In the kana-kanji conversion device configured as shown in Figure 1,
When "karidasu" is input from the input device 1, conventionally, when the dictionary search unit 2 searches the word dictionary 8 as shown in FIG. On the other hand, "borrow", "borrow", "eject",
"Hunting out."

“Hunting out” was displayed on the selection screen of display device 5, but 1
In this embodiment, regarding different notations of homophones and synonyms, only the display marker II 1/7 is displayed, and the display marker "
Since 0'' is not displayed, the display marker re 1 n of "borrow", "eject", and "hunt" are displayed on the selection screen for the reading "karidasu". It turns out.

FIG. 4 is a diagram showing an example of a word selection display after the variant notation key is pressed according to the present invention. Here, the different notation keys used are: If you want to change the advance, the display marker is LL I
It would be a problem if it were only displayed when it is in
The notation (word) of Ott can also be displayed.

For example, the user wanted to convert ``karidasu'' into ``borrow'', but at the beginning of the word dictionary 8, the display marker was changed from the notation ``borrow'' to t l +y2 ``borrow''. ” is 0”, “borrow” is not displayed on the selection screen of the display device 5. Therefore, press the different spelling key to display all the homophones, and then click "borrow"
You will have to choose. FIG. 4 shows the state displayed on the selection screen in this manner. When "borrow" is selected in state 1 shown in FIG. 4, the display marker rewriting unit 7 rewrites the display marker, and the notation "borrow" becomes II 111, and the notation "borrow" becomes II 111. II Opg. Therefore, from now on, "borrow" will be displayed first. This example is shown in Figure 5.
It is shown in FIG. Figure 5 shows the synonym for the notation “borrow”.
This figure shows the state of the word dictionary 8 when "borrow" is selected. Moreover, FIG. 6 shows the word selection display after the synonym "borrow" of the notation "borrow" is selected.

FIG. 7 is a diagram showing the state of the dictionary buffer 4 after reading data from the word dictionary 8 by the dictionary search unit 2. Here, the expressions ``borrow'' and ``eject'' are used.

The display marker for "hunt out" is rr I IF, and the display marker for "borrow" and "hunt out" is 1'0''.

FIG. 8 is a diagram showing the state of the dictionary buffer 4 rewritten by the display marker rewriting unit 7 of the present invention. This shows a state in which the different notation key has been pressed and "borrow" has been selected, and the display marker in the dictionary buffer 4 in FIG. 7 has been rewritten by the display marker rewriting unit 7.

FIG. 9 is a diagram showing the flow of word selection processing according to the present invention. The word selection process will be described below with reference to FIGS. 7 to 9.

First, the pronunciation of a word (in this case, ``karidasu'') is input from the input device W1, and when the conversion key on the input device 1 is pressed, a flag a (here, flag a indicates the normal display or (“O”), display including different notations (“1”),
Alternatively, the synonym marker (which indicates rewriting ("2")) is set to re Otr, and control is transferred to the dictionary search unit 2 (step 901). In the dictionary search section 2, after reading the notation, synonym marker, and display marker of the word whose pronunciation is "karidasu" from the word dictionary 8 into the dictionary buffer 4 (see FIG. 7), control is transferred to the display section 3. (Step 902)
. The display unit 3 displays a word selection screen by looking at the dictionary buffer 4 and flag a.

In this embodiment, homophones are displayed in a matrix as shown in FIG. 3, and selected by pressing the corresponding key on the numeric keypad. Additionally, keys corresponding to the different notation keys can be positioned anywhere on the numeric keypad. When flag a = O, the display marker is II 11
If flag a≧1 is selected, all the notations are displayed (see FIG. 4). At this time,
As shown in FIGS. 3 and 4, synonymous markers other than II OF+ are displayed in a small size on the right shoulder of the notation. Further, a message may be displayed according to the value of plug a. If there are too many different notations to fit on one screen, split them into multiple screens.

When the word selection screen as shown in Fig. 3 is displayed, press the key corresponding to the variant spelling key.

The value of plug a is rewritten to N 1 sr, and display section 3
As shown in FIG.
On the selection screen; all are displayed. When the desired notation is selected by operating the numeric keypad and the process proceeds to the next step (after the selected notation is displayed at a predetermined position in the document), control is transferred to the display marker rewriting unit 7 (step 903). . Here, it is assumed that "borrow" is selected after the different notation key is pressed. The display marker rewriting unit 7 does nothing when the synonym marker of the selected word is 0'', and the synonym marker is It O.
If it is not II, first set the display marker of the selected notation to II 171, then rewrite all display markers other than the selected word whose synonym marker has the same value as the selected word to IF O17 (No. (See Figure 5). The word dictionary may be rewritten by first rewriting the values in the dictionary buffer 4 as shown in FIG. 8, and then rewriting the word dictionary 8 as shown in FIG. Through the above processing, the dictionary is rewritten and the word selection processing is completed.

Next, rewriting of synonymous markers in the word dictionary 8 will be explained.

Whether two words with the same reading are synonymous or not is
This is determined when the dictionary is created, but you may want to change it. For example, the pronunciation ``jubun'' and the notation ``sufficient'' and ``sufficient'' can be said to be homophones, but some users may want to use it with a different meaning, and ``sufficient'' is not considered a synonym. In some cases, ``desu'' and ``karidashi'' are used interchangeably. these are,
This is possible by rewriting synonymous markers in the dictionary.

FIG. 10 is a diagram showing the flow of processing for rewriting synonymous markers according to the present invention. Synonymous marker rewriting will be described below with reference to FIG.

First, a kana character string (word) is input from the input device 1,
When you press the key corresponding to the different notation key, flag a is changed to N 2
17, control is transferred to the dictionary search unit 2 (step 100
1). The dictionary search unit 2 performs the same process as the word selection process described above, and transfers control to the display unit 3.
will be displayed on the selection screen (step 100).
2). The selection screen display on the display device 5 indicates that the flag a≧
Because it is 1.

As shown in FIG. 4, words whose display marker is 0'' are also displayed.

Here, by operating the numeric keypad to select one word and pressing the execution key, proceed to the synonym marker rewriting section 6 (step 10
03). The synonymous marker rewriting unit 6 performs the following processing depending on the value of the synonymous marker of the selected word.

(a) When the synonym marker is '0'' First, words excluding the selected word are displayed. If you select again, the first word and second word are considered to have a synonymous relationship. Do it like this.

(i) If the second word's synonym marker is II OII, a new synonym set is created and the two words are given a synonym marker value that was not previously in their reading. (
ii) If the second word's synonym marker is not '0.', make the first word's synonym marker the same as the second word's synonym marker.

Regarding the new set of synonyms that can be created using the above (iL(ii)), we decided to rewrite the display marker at the same time, so that only one of the synonyms is displayed on the first screen when selecting a word. Good too.

For example, methods such as making it the first selected word or making an inquiry can be considered.

(b) If the synonym marker is not It Oyy If there is one word that has a synonym marker with the same value as the synonym marker of the selected word, both words that have a synonym marker with the same value as the synonym marker of the selected word The synonymous marker for the word is rewritten to 0" and the display marker is rewritten to II 1 pg. Thereafter, the synonymous markers other than NO+y are reassigned in order from '1" so that there is no space left. In addition, if there are multiple words, only one selected word,
Rewrite the synonym marker to 0'' and the display marker to It 11H.

In this way, in this embodiment, since only one word with a homophone and a different spelling is presented as a candidate, the number of word candidates to be selected is reduced, and the user can choose from fewer candidates. The burden is reduced. Note that once a notation has been selected, words with homophones and synonyms in different notations are not selected as candidates, so that the consistency of the notation can be maintained. Furthermore, in this embodiment, the synonyms displayed on the selection screen of the display device 5 when flag a = 0 are determined at the time of creating the word dictionary, as shown in FIG. By setting 1'' to 1'', all synonyms can be displayed and narrowed down as they are used. An example of the structure of this word dictionary is shown in FIG.

Effects As explained above, according to the present invention, in a kana-kanji conversion device that displays homophones from a word dictionary as candidates,
Even if the words are homophones, one candidate is selected for homophones, synonyms, and different notations, making it easier to select homophones, reducing the burden on the operator, and ensuring uniformity in notation of sentences.
