Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for creating a sentence by inputting a word and an apparatus for the same.

[0002]

2. Description of the Related Art Recent mobile phone devices and PHS not only have a telephone directory function that can store a telephone number and the name of the other party as a pair, but also have a high function and an e-mail due to the expansion of use. Features have become commonly used. For this reason, it has become an important requirement that not only the input of Chinese characters such as a person's name but also the convenience of inputting a text such as a message is performed.

On the other hand, since there is a growing demand for miniaturization of devices, it has become more important than ever to be able to efficiently create sentences with a small number of operations using a small number of keys.

Due to the limitation of the device implementation that the number of keys must be reduced as described above, generally, the character input method in a portable telephone device is such that the ten keys of "1" to "0" have 50 syllabaries. Is adopted, and the character of each assigned line is sequentially changed according to the number of times the ten key is pressed. With this method,
For example, in order to input "O", it is necessary to press the "1" key on the numeric keypad five times. Therefore, there is a problem that as the number of input characters increases, the number of times the ten keys are pressed increases enormously.

For the purpose of reducing the number of times of pressing such a key, for example, Japanese Patent Laid-Open No. 2001-242996.
In (Prior example 1), a method is proposed for reducing the number of key operations for giving a dull sound / semi-dumb sound. Figure 6
Also in the first example shown in FIG.
Each row of the Japanese syllabary is assigned to each of the ten keys of "9". For example, the numbers "1" to "9" on the numeric keypad, the hiragana line to "la" line, the "0" key to the line "wa",
“O” and “n” are assigned to dakuon and semi-dakuon.

When the numeric keypad 111 of the input unit 110 is pressed and then the "0" key is pressed, the character determination unit 150 causes the character one character before the cursor displayed on the display unit 130 to become a dull sound or It is determined whether or not the character can be added with the semi-voiced sound, and based on the result, when the character can be added with the voiced sound or the semi-voiced sound, when the "0" key is continuously pressed, The display unit 130 displays the voiced sound or the semi-voiced sound prior to the normal characters, and if not, "wa",
The order of appearance of “” and “n” is controlled to precede. As a result, it is possible to reduce the number of key operations required to generate a dull sound or a semi-dumb sound without reducing the input efficiency of the normal characters "wa", "wo", and "n".

By using the method of the prior art example 1, when the name of the communication partner is registered in Japanese in the telephone directory in the portable telephone device, it is possible to simplify the operation relating to the generation of the voiced sound or the semi-voiced sound. .

[0008]

However, as mentioned above, in the case of sending a mail using a mobile phone device, a text creation device for efficiently performing a message input process. It has become indispensable to improve the operability. On the other hand, in the writing of Japanese sentences, various particles are connected to the nouns, and the verbs have various inflectional forms. Therefore, if it is possible to omit the input of the participle of a particle or a noun, it is expected that the number of input characters will be reduced and a sentence will be created comfortably.

As this type of sentence creating technique, a prediction technique (suffixing technique) for predicting the continuation based on the Japanese input up to the middle of a word has been conventionally known. However, in the case of the word completion type prediction technology, the number of candidates for the use of adjectives and the connection of particles is often huge, and unless a limited display screen such as a mobile phone device is used. If not, it is likely that only a small number of candidates will be displayed.

For this reason, as a technique for creating a sentence in consideration of a usage of a noun and a connection of particles, for example, Japanese Patent Laid-Open No. 59-59
As with the document creation device disclosed in 163638 (Prior example 2), it is limited to be used as an auxiliary means for testing the validity of the inflection ending of the input character string input by the user, It was difficult to use to generate documents.

The object of the present invention is to solve the above problems,
An object of the present invention is to provide a method for effectively creating a sentence by simply inputting a simple word and a device using the same when creating a Japanese sentence using a small number of buttons like a mobile phone device. .

[0012]

In order to achieve the above-mentioned object, in the sentence creating method according to the present invention, a sentence creating method is provided in which a sentence is created by inputting kana characters, and the kana characters to be input are body words or words. After selecting only one of the candidate words obtained by converting the basic form of the word, which consists of the final form of the word, and if the selected word is a declinable word, the candidate phrase of the inflectional form of the declinable word When the selected word is a word, a list of candidate clauses to which particles that can be connected to the word are added is generated, and a desired candidate clause is selected to sequentially generate sentences.

Further, a list of candidate clauses following the Kanji-converted word is provided in advance, and a process of directly converting the Kana-character-input words into Kanji characters and a list of candidate clauses predicted from the converted candidate words are displayed. Then, a process of selecting and confirming a specific candidate phrase from among them is performed.

Further, a desired candidate word is selected, a dictionary is searched to classify the part of speech of the candidate word, and if the part of speech is a noun, a conjugation form of the part of speech is generated and a candidate phrase is generated. A process of displaying a list, a process of displaying a candidate phrase in which a particle that can be connected to a noun is connected if the classified part-of-speech is a noun, and a desired phrase is selected from the listed candidate phrases and sequentially selected. And a process of generating a sentence.

In addition, a step of performing kanji conversion for the input noun or adjective infinity, selecting a desired candidate word and fixing it, searching a dictionary, and classifying the part of speech of the word, In the case of a noun that is classified into any of the verbs, adjectives, and adjectives according to the classified part-of-speech information, the inflected form of that part of speech is generated as a candidate phrase, and when the classified part-of-speech is a noun Includes a step of generating a candidate phrase in which particles that can follow the body language are connected,
A processing procedure including a step of displaying a list of candidate phrases of generated generated phrases or a phrase and a step of selecting an intended candidate phrase from the candidate phrase list and confirming it as a phrase is repeated, and the processing procedure is repeated. By executing, the Japanese sentence is generated only by inputting the final form of the body phrase or the idiom.

Further, the sentence creating device according to the present invention is a sentence creating device which creates a sentence from word input by kana characters, and is provided with a phrase candidate completion key for instructing to perform phrase completion, and the kana character When converting the input word as it is to Kanji, select the converted candidate word without operating the phrase candidate completion key and confirm it. To generate the phrase, select the converted candidate word. Then, by pressing the phrase candidate complement key, a list of candidate phrases predicted from the converted candidate words is generated, and the candidate phrase is selected and confirmed.

Further, a sentence creating device having an input device, a display unit, a dictionary, and a control device, has a phrase candidate complement key for instructing to perform phrase complement, and the input device is a kana character. Then, the control device refers to the dictionary, displays the Kana-converted candidate word of the kana-character-input word on the display unit, and selects the word to convert it independently. The candidate word is fixed as it is, and when creating a sentence, select the desired candidate word and then press the phrase candidate complement key to determine whether the part of speech of the selected candidate word is a noun or a noun. If it is determined to be a word, a list of candidate phrases in the inflected form of the candidate word is displayed on the display unit, and if the part of speech of the candidate word is determined to be a synonym, a candidate with a particle that can be connected to the candidate word is added. List the clauses on the display and It is to create a sentence by selecting a desired phrase from the candidate phrase that appears.

Further, the input device is constituted by a ten-key pad of a portable telephone device.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

(Structure of Embodiment) The present invention is a method for creating a sentence by inputting kana characters, and an apparatus for realizing this method. If the kana character to be entered is only the basic form of a word consisting of the end form of a noun or a noun, select one of the candidate words obtained by converting the basic form of the word, and if the selected word is a noun , A candidate phrase list of inflectional forms of the idiom, and when the selected word is a nominative phrase, a candidate phrase list with a particle that can be connected to the nominative phrase is generated, and by sequentially selecting the desired candidate phrase, Generate sentences. A configuration according to the embodiment of the present invention is shown in FIG. A sentence creation device for creating a sentence by inputting kana characters according to the present invention displays an input device 101 and a control device 102 for inputting a reading of a word, a dictionary 103 for acquiring a part of speech of an input word, and an input result and a conversion result. The display unit 104 is included.

The details of the input device 101 are shown in FIG. The input device 101 has a ten-key unit 202 for sequentially inputting characters and a phrase candidate complement key 201 as a dedicated key for instructing to perform phrase complement. Each row of the Japanese syllabary is assigned to each of the ten keys “1” to “0” in the ten key unit 202. For example, the numbers “1” to “9” on the numeric keypad and the letters “wa”, “o”, and “n” in the hiragana line and the “0” key.
And voiced sound and semi-voiced sound are assigned. The assigned characters on each line change sequentially depending on the number of times the button is pressed.

By operating the ten-key unit 202, the input device 101 executes an input process using kana characters, inputs a series of hiragana characters, and then displays conversion candidates by operating a conversion key (not shown). A desired conversion result is selected from the words. For input that may be fixed as it is, such as input of a name to be stored in the telephone directory, it is selected from candidate words and fixed immediately.

On the other hand, when generating a sentence, a desired candidate word is selected and the phrase candidate complement key 201 is pressed. As a result, the control device 102 searches the dictionary 103 and classifies the part of speech of the candidate word.

Further, in accordance with the classified part-of-speech, various inflectional forms are generated, and candidate phrases are displayed in a list on the display unit 104. When the classified part-of-speech is a noun, the display unit 104 displays a candidate phrase in which a particle is connected to the input word. Next, by selecting a desired phrase from the candidate phrases displayed in the list, sentences are sequentially generated.

(Description of Operation of Embodiment) Next, the overall operation of this embodiment will be described in detail with reference to the flowchart of FIG.

First, according to the conventional input method described above, only the basic form of a word is input from the ten-key unit 202 of the input device 101 (step 301). The basic form of the word is
In the case of idioms, the final form is used.

Kanji conversion is performed on the final form of the input word, the target candidate word is selected, and then the phrase candidate complement key 201 is pressed (step 302). The control device 102 searches the dictionary 103, The part of speech of the word is classified (step 303).

In the case of a noun that is classified into any part of speech of a verb, an adjective, and an adjective verb based on the classified part-of-speech information, an inflectional form corresponding to the part of speech is generated as a candidate clause. If the classified part of speech is a noun (noun),
A candidate phrase is created by connecting particles that can follow the word.

Next, a list of the generated candidate phrases or noun phrases is displayed on the display unit 104 (step 30).
4). The operator selects an intended candidate phrase from the candidate phrase list, confirms it as a phrase, and completes character input to the editing screen (step 305). By repeating the above operation, a Japanese sentence can be generated only by inputting a word.

FIG. 4 shows a specific example of the processing operation in the case of a noun. Now, as an example, "must write"
Assuming that the user wants to create the sentence, in FIG. 4, the character "Kaku" is input from the ten-key unit 202 as the final form of the verb (character editing screen 401).

By converting the reading of this kana character, for example, as a candidate word, {writing / scratching / missing /
Thus, words such as / each} are displayed (character editing screen 40
2). From among these, by selecting the desired word 404 "writing" and pressing the phrase candidate complement key 201,
The control device 102 searches the dictionary 103 and determines that “writing” is a verb.

According to this judgment, candidate clauses such as {If you write / If you do not write / Write / When you write / If you write} are displayed as candidates for the verb "writing" (character editing screen 403). From these candidate clauses, select the target sentence "Do not write" and confirm.

In the conventional prediction technique, for example, when the word "kaku" is input and predicted, only the clauses in which the word "kaku" prefixes are predicted and the candidates are covered. Since the object to be complemented is the inflectional form from the basic form of the word, the number of candidates can be efficiently narrowed down, and comfortable character input can be supported.

Therefore, it is possible to obtain candidate clauses that have been changed by the complementary operation, including the part "ku" that was originally input, such as "written", from the word "ku" in FIG. (The "ku" part changes to "ki").

FIG. 5 shows a concrete example of the processing operation in the case of a word. Now, taking the case where it is desired to create the sentence “in the machine”, the character “kikai” is input from the ten-key unit 202 in FIG. 5 (the character editing screen 50).
1).

When the reading of this kana character is converted, a candidate word, for example, {machine / opportunity / strange / kikai / instrument}
A word such as is displayed (character editing screen 502). By selecting a desired word 504 “machine” from among these and pressing the phrase candidate complement key 201, the control device 10
In step 2, the dictionary 103 is searched, and it is determined that “machine” is a word.

In accordance with this determination, candidate clauses such as {machine // machine / machine / machine / machine} are displayed as candidate particles as candidates for connection of particles suitable for the noun "machine".
04 (character edit screen 503). From these candidate clauses, the target sentence "in the machine" is selected and confirmed.

By executing the above processing,
Simply enter a word sequence
The sentence "You must write. On the machine ..." will be generated.

[0039]

As described above, according to the present invention, when creating a Japanese sentence, it is possible to omit the input of a particle or an inflection part of a noun, and generate a sentence only by inputting a word. In a device with few keys, such as a mobile phone device, it is possible to comfortably create a sentence by inputting a small number of characters.

Further, by selecting and generating the candidate phrases only by using the inflected forms of the idioms and the postpositional particles, the list of candidate phrases can be efficiently presented even on a limited display screen such as a portable telephone device. can do.
