Abstract

PURPOSE:To improve operationability by simultaneously conversion-processing plural words when they are in an example dictionary without processing a word one by one in the conversion-processing of a homonym. CONSTITUTION:A KANA Japanese syllabary string inputted from an input means 103 is punctuated at a clause unit by a KANA/KANJI Chinese character 104, the KANA character strings of the respective clauses are respectively converted into plural word candidates by the reference of a KANA/KANJI converting dictionary 101 and a word selecting means 105 selects the effectively combined words from the converted word candidates based on the example of an example dictionary 102. When conversion into the homonym is indicated, another effectively combined words which are different from those selected by the word selecting means 105 based on the example stored in the example dictionary 102 are selected from the word candidates converted by a same sound word selecting means 106 and are displayed in a display means 107.

Description

Detailed Description of the Invention [0001] [Industrial Application Field] This invention is used in a document processing device such as a Japanese word processor or a computer capable of creating documents in Japanese, and is used to process input kana character strings. This invention relates to a kana-kanji conversion device that converts sentences into kanji-kana mixed sentences. [0002] In a conventional kana-kanji conversion device, for example, when converting kana to kanji for ``shincho wo'', the two words ``shincho wo'' and ``measure'' are converted in consecutive clause conversion.
They divide it into phrases, create homonyms for each, and select the most likely candidate among them using various methods. This ranges from "measuring height" by simply converting each word based on the frequency of each word to "measuring height" by simply converting each word based on the frequency of each word.
If the desired word is not displayed, the next option key is used to select a homophone for each word. [Problem to be solved] In the conventional kana-kanji conversion device as mentioned above, for example, in the case of the word ``suishin wo kaeru,'' both ``promote'' and ``measure water depth'' are correct Japanese sentences. Therefore, if both examples are registered in the example dictionary, only the example with the highest priority will be displayed, and the other one will be hidden. Therefore, this hidden one will be used as the next candidate key. When selecting, one word at a time, the words in the example dictionary were wasted. In other words, as shown in FIG. If you select the next candidate while the result is displayed, only the next candidate for the word in the phrase at the cursor position, which is underlined, will be displayed. A problem arises in that other examples of the same pronunciation of ``measure'' are not utilized. [0005] In view of the above, the present invention does not perform the conversion process for each word one by one when converting homophones, but instead converts the homonyms by converting the homonyms if they are in the example dictionary. , the object is to improve operability by performing homophone conversion processing for multiple words at the same time. [Means for Solving the Problems] FIG. 1 shows the configuration of the present invention. 1 is a block diagram. As shown in the figure, the kana-kanji conversion device according to the present invention includes a kana-kanji conversion dictionary 1 in which a large number of words including kanji are stored in advance together with their reading information.
01, an example dictionary 102 in which valid combinations of words are stored in advance as examples, and an input means 1 for inputting kana character strings and instructing conversion to homophones.
03, and divides the kana character string input from the input means 103 into phrases, and refers to the kana-kanji conversion dictionary 101,
A kana-kanji conversion means 104 that converts the kana character string of each clause into a plurality of word candidates, and a kana-kanji conversion means 104
The example dictionary 102 is selected from among the word candidates converted by
word selection means 105 for selecting effective combinations of words based on usage examples stored in the word selection means 103;
When an instruction is given to convert from to a homophone, a plurality of words are selected by the word selection means 105 from among the word candidates converted by the kana-kanji conversion means 104 based on the usage examples stored in the example dictionary 102. a homophone selection means 106 for simultaneously selecting other valid combinations of words different from the words selected by the user; and a display means 107 for displaying the words selected by the word selection means 105 and the homophone selection means 106. , and configure it. [0007] Note that as the kana-kanji conversion dictionary 101 and the example dictionary 102 in this invention, an internal memory such as a ROM, or an external storage device such as a floppy disk device or a magnetic disk device is used. The input means 103 may be any device capable of inputting a kana character string and instructing conversion into homophones, and may be an input device such as a keyboard device, a tablet device, or a pointing device. [
[0009] Kana-kanji conversion means 104, word selection means 10
5 and the homophone selection means 106 include a CPU, a ROM
It is convenient to use a microcomputer consisting of , RAM, and I/O ports. The display means 107 may be a CRT display device, an LC (liquid crystal) display device, or an E
An L display device or the like is used. [Operation] According to the present invention, the kana character string inputted from the input means 101 is divided into phrases by the kana-kanji conversion means 104, and the kana characters of each phrase are determined by referring to the kana-kanji conversion dictionary 101. Each string is converted into a plurality of word candidates, and the word selection means 105 selects effective combinations of words from among the converted word candidates based on the examples in the example dictionary 102. [0012] Then, when the input means 103 instructs conversion to a homophone, the homophone selection means 106 performs the following steps.
From among the word candidates converted by the kana-kanji conversion means 104, based on the examples stored in the example dictionary 102,
Other valid combinations of words different from the words selected by the word selection means 105 are selected,
It is displayed on the display means 107. [0013] Therefore, since the homophone conversion process is performed for a plurality of words at the same time, operability is improved. DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on embodiments shown in the drawings. Note that this invention is not limited to this. FIG. 2 is a block diagram showing the configuration of an embodiment in which the present invention is applied to a Japanese word processor. In this figure, 1 is a keyboard equipped with kana character keys, numeric keys, conversion keys, next candidate keys, function keys, etc. It is used to input data of various kana character strings, and also provides instructions for conversion to homophones. Data is input to the control section 2. [0016] The control unit 2 includes a CPU, ROM, RAM, I
The control program is configured by a microcomputer having a /O port, and performs various data processing described below using a control program written in a program memory 3 consisting of a ROM. Reference numeral 4 denotes a kana-kanji conversion dictionary consisting of a ROM, which stores reading information and frequency information relating to the frequency of appearance of a large number of words including kanji. Reference numeral 5 denotes an example dictionary consisting of a floppy disk device, and this example dictionary 5 has connection information between two words. That is, effective combinations of two words are stored in advance as examples. Reference numeral 6 denotes a kana-kanji conversion device consisting of a microprocessor, which divides the kana character string input from the keyboard 1 into phrases, refers to the kana-kanji conversion dictionary 4, and converts the kana character string of each phrase into a plurality of phrases. Convert each to word candidates. Reference numeral 7 denotes a kana-kanji conversion result buffer consisting of a RAM, which stores the kana-kanji conversion result consisting of word candidates converted by the kana-kanji conversion device 6. 8 is a text buffer consisting of RAM;
A kana character string input from the keyboard 1 and a kanji-kana mixed sentence selected from the kana-kanji conversion candidates stored in the kana-kanji conversion result buffer 7 are stored. Reference numeral 9 denotes a CRT display device, which displays the kana character string input from the keyboard 1, the conversion candidates stored in the kana-kanji conversion result buffer 7, and the text buffer 8.
Displays the memorized kanji and kana mixed sentences. The control unit 2 stores the kana-kanji conversion result buffer 7
Based on the examples stored in the example dictionary 5, effective combinations of words are selected from among the conversion candidates stored in the example dictionary 5 and displayed on the CRT display device 9. Then, when conversion to homophones is instructed from the keyboard 1, from among the conversion candidates stored in the kana-kanji conversion result buffer 7, based on the usage examples stored in the example dictionary 5, the current Other valid combinations of words different from the selected words are simultaneously selected and displayed on the CRT display device 9. FIG. 3 is an explanatory diagram showing an example of the stored contents of the kana-kanji conversion dictionary 4. As shown in the figure, the kana-kanji conversion dictionary 4 stores headings, registered words, parts of speech, etc. For example, in the heading “Suisin”, the registered words “propulsion”, “water depth”, and “orthocenter” are stored, and in the heading “measurement”, the registered words “measure”, “
``Aim'', ``Consult'', ``Measure'', ``Weigh'', and ``Plan'' are stored. FIG. 4 is an explanatory diagram showing an example of the stored contents of the example dictionary 5. In the example dictionary 4, for example, in the pronunciation of ``to measure water,''``propulsion'' and ``water depth'' are stored as the preceding words, and ``measure'' and ``measure'' are stored as the subsequent words. Two examples are prepared as conversion candidates for ``measure the depth'': ``propel the water'' and ``measure the water depth.'' When the control unit 2 inputs the kana character string from the keyboard 1, The kana character string is stored in the sentence buffer 8. Then, when the conversion key is pressed, an instruction is given to the kana-kanji converter 6 to divide the kana character string into phrases, and the kana-kanji conversion dictionary 4 divides the kana character string into phrases. In addition to performing kana-kanji conversion, the example dictionary 5 is searched for examples, and the kana-kanji conversion dictionary 4 is searched for word frequency information. Learning information is then searched from a learning buffer (not shown) and scored. , the word written with the highest score is displayed on the screen of the CRT display device 9. FIG. As shown in this figure, "to promote" and "to measure water depth" are stored in the example dictionary 5, but "to promote" with a high score is displayed. Keyboard 1 as shown
When the next candidate key is pressed, the control unit 2 searches the homophone analysis results for the next candidate for "measure" and finds "measure", and since this "measure" has "water depth" in the example, Displays the next option for “promotion”, “water depth”, and displays the next option for “measure”, “measure”. If there is no example, only the next candidate at the cursor position indicated by an underline is displayed, such as ``measure'', which is the next candidate for ``measure'' in ``measure water depth''. Note that in this next candidate processing, the clause break positions may be different. Next, the contents of the processing operation of the control section 2 will be explained according to the flowchart shown in FIG. The control unit 2 first waits for a key input (step 21), and when there is a key input, it checks whether the input content is a character string (step 22), and if it is a character string, it inputs the input character string. The text is stored in the text buffer 8 (step 23). [0030] Also, if it is a conversion key (step 24)
, divide the kana character string stored in the sentence buffer 8 into phrases (step 25), search for examples in the example dictionary 5 (step 26), and search for frequency information (step 27).
Further, the learning information is searched (step 28), and candidates for maximum score data are displayed on the CRT display device 9 (step 29). When the key input in step 21 is the next candidate key (step 30), a combination of examples is searched (step 31), it is checked whether or not there is a combination (step 32), and if there is a combination, the previous one is After changing the word (step 33), the subsequent word is changed (step 34). If there is no combination, only the previous word is changed (step 35) and the process returns to step 21. Note that if the key is not the next candidate key in step 30, other processing is performed. In this way, by performing homophone conversion processing on two words at the same time, for example, “
In the case of "Measure water depth", even if you input "Measure water depth" and "Promote" is displayed, you can select "Measure water depth" by pressing the next candidate key once. [Effects of the Invention] According to the present invention, when conversion into homophones is instructed, a plurality of words can be converted based on the usage examples stored in the example dictionary. , other valid combinations of words different from the currently selected words are selected and displayed at the same time, improving operability.
