Abstract

PURPOSE:To improve the operatability of the titled device by registering a word adopted by 'KANA' (Japanese syllabary)/'KANJI' (Chinese character) conversion processing in a user dictionary, selecting a system dictionary or the user dictionary, switching the dictionary to be used on the way of 'KANA'/'KANJI' conversion processing, and executing said processing again. CONSTITUTION:An input part 1 is provided with a selection key 909 for selecting one of 'KANA'/'KANJI' conversion candidates in addition to a conversion key 903 for instructing the start of 'KANA'/'KANJI' conversion processing, a system dictionary conversion key 905, a user dictionary conversion key 911, and so on. When the result of 'KANJI' conversion is not a purposed candidate at the time of inputting a reading character and the key 903 and converting the user dictionary, the change is requested by using the key 909 and its corrected result is registered in the user dictionary to continue the conversion of the user dictionary.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a kana-kanji conversion device that converts a kana input string into a character string containing kanji and kana, and particularly relates to the control of a kana-kanji conversion dictionary used when performing kana-kanji conversion. .

[Conventional technology]

Conventionally, a system dictionary unique to a system in which kana character strings input using an input device such as a keyboard are prepared in advance,
There is an efficient conversion method that uses a user dictionary created by storing the words used by the user in the kana-kanji conversion process in a predetermined internal area. There is a method described in ``Dictionary File Access Method'', published in 1986-117366.The method described in this document reads words used in sentences from the system dictionary and reserves them in the user dictionary. When converting a kana character string to a character string containing kanji and kana, first access the user dictionary to determine whether a candidate exists, and if there is no candidate, access the system dictionary and convert it to a character string containing kanji and kana. In this method, when converting to a candidate existing in the user dictionary, the system dictionary is not searched, so the conversion becomes faster and conversion efficiency can be improved.

(Problems to be Solved by the Invention) In the prior art, when a candidate exists in the user dictionary, the system dictionary is not searched.
Once you use the word ``Kisha'' for the reading ``Kisha'', the next conversion for the reading ``Kisha'' will always be ``Your company'', and the words ``train'' and ``reporter'' will be changed. The problem is that it cannot be converted. In other words,
If a word has so-called homonyms, which have the same pronunciation but different meanings, there is a problem in that only one of the words can be used.

The present invention aims to improve the inconvenience of kana-kanji conversion processing using a system dictionary and a user dictionary in such conventional kana-kanji conversion devices, and to provide a kana-kanji conversion device with good operability and conversion efficiency.

[Means for Solving the Problem] In order to solve this problem, the present invention provides a kana-kanji conversion device that searches a kana-kanji conversion dictionary for a kana-kana character string input from an input device and converts it into a character string containing kanji and kana. A system dictionary specific to the system provided as the kana-kanji conversion dictionary and a user dictionary in which words adopted in the kana-kanji conversion process are registered, and words adopted in the kana-kanji conversion process are automatically registered in the user dictionary. A user dictionary registration means, a used dictionary selection means for selecting which of the system dictionary and the user dictionary to perform the kana-kanji conversion process, and a dictionary to be used during the kana-kanji conversion process is switched and the kana-kanji conversion process is performed again. It is characterized by having a kana-kanji conversion reprocessing means.

[Effect]

When you create a kanji-kana mixed character string from the input kana character string using the system dictionary, the adopted word will be automatically registered in the user dictionary, and then the user dictionary will be used to perform the kana-kanji conversion process. and qualified conversion candidates can be extracted.

Furthermore, even during the kana-kanji conversion process, it is possible to switch dictionaries and execute the kana-kanji conversion process again.

〔Example〕

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

FIG. 2 is a block diagram showing the configuration of the kana-kanji conversion device according to the present invention, which includes an input section 1, a display section 4, a control section 2, a storage device 5, and an external storage device 3.

The input unit 1 is an input device for inputting input reading character strings, conversions, selection instructions, etc., and the display unit 4 includes, for example, a CRT display for displaying input reading characters, conversion results, etc. The control unit 2 is in charge of executing kana-kanji conversion and is configured using a CPU. The memory bag W5 is a place where programs, data, etc. are stored, and the external storage device 3 is a place where words used by the operator, documents created, etc. are stored.

FIG. 3 is a diagram showing the key arrangement in the input section 1. As shown in FIG.

901 is the Japanese syllabary key, which simply means not only hiragana characters but also all characters to be converted into kana-kanji. 903 is a conversion key for instructing the start of the ephemeral-kanji conversion process; 905 is a system dictionary conversion key for instructing the kana-kanji conversion process using the system dictionary; 907 is an end key for instructing the end of document creation work; 909 is the ephemeral-kanji conversion candidate Selection key for selecting one of (homonyms), 9
Reference numeral 11 is a user dictionary conversion key that instructs kana-kanji conversion processing using the user dictionary, and 913 is an editing work key that instructs work to make the created document more beautiful by adding underlines to characters or making them double-width. be.

FIG. 1 is a processing flowchart of the Honkana-Kanji conversion device, and the processing contents will be explained below.

When the operator starts up the system, the control unit 2 first processes the area (hereinafter referred to as a temporary storage buffer) that holds the input reading characters in process 10 and the registration flag (hereinafter referred to as "temporary storage buffer") that manages whether or not to register them in the user dictionary. Initial processing such as clearing the FLG (called FLG) to O is performed. Here, F.L.
When G is 0, it means that there is no need to register in the user dictionary, and when FLG is 1, it means that it is necessary to register in the user dictionary. In process 15, the key input by the operator is taken in, and the input key is analyzed in the following process. If the input key is the end key 907 in process 20, document registration process 85 is performed and the control process ends. The document registration process here refers to the process of storing a created document, etc. in the external storage device 3 shown in FIG. 2, such as a floppy disk. The determination result of process 20 is "end key"
If not, in step 25, the input key is the 50-on key 9.
01 is determined. If the input key is the "Japanese syllabary key", it is first determined in process 45 whether FLG is 1, and if FLG is 1, the word to be used is registered in the user dictionary in process 50, and then in process 55 Then, the FLG is set to 0 and the input reading character storage process 60 is performed. FLG in process 45
When is O, the input reading storage process 60 is immediately performed. If the input key is not the "Japanese syllabary key" in process 25, it is determined in process 30 whether it is the system dictionary conversion key 905 or the user dictionary conversion key 911. The input key is the system dictionary conversion key 905 or the user dictionary conversion key 91
If it is 1, it is determined in process 65 whether FLG is 0, and if FLG is O, a dictionary to be used during conversion is set in process 70. In process 65, FLC is 1
In this case, the kana-kanji conversion process 90 is performed using the dictionary corresponding to the input key. In process 30, the input key is the system dictionary conversion key 905 or the user dictionary conversion key 91.
If it is not 1, it is determined in process 35 whether it is the conversion key 903 or not. If it is the conversion key 903, a kana-kanji conversion process 90 is performed; if not, a process 40 determines whether it is the selection key 909; if it is a selection key 909, a kana-kanji conversion process is performed in process 90. If they are different, it is determined whether FLG is 1 in process 45', and FLG is set to 1.
If LG is 1, the word to be used is registered in the user dictionary in process 50'', FLG is set to 0 in process 55'', processing 75 is performed for editing work, and the temporary memory buffer is cleared in process 80. Processing is a process that makes a created document more beautiful by underlining characters or making them double-width.

The operations of the input reading character storage process 60, dictionary mode switching process 70, kana-kanji conversion process 90, and user dictionary registration process 50 and 50' described above will be explained in more detail below.

FIG. 4 is a flowchart showing the operation of the input reading character storage process 60. In process 602, the reading characters input from the input unit 1 are stored in a temporary storage buffer. The storage location is the number of input readings (YOMI C) in the temporary storage buffer.
NT)th. Here, input reading number (YOMI C
NT) is used to manage the number of input reading characters that have not yet been converted, and is cleared to 0 as an initial state at the start of input (. YOMI CNT is increased by 1 in process 604, and YOMI CNT is increased by 1 in process 606. The input reading characters are displayed on the display section 4.

For example, as shown in Figure 8, "Kishade Kakko ni Iku"
If you enter , the characters will be entered in order from address O in the temporary storage buffer: ``ki'', ``shi'', ``ya'', ``de'', ``ga'', ``tsu'', ``
Input reading characters such as ``ko'', ``u'', ``ni'', ``i'' and ``ri'' are stored, and the input reading character strings are displayed on the display unit 4 so that the operator can understand them.

Next, the operational flow of the dictionary mode switching process 70 shown in FIG. 1 is shown in FIG. In process 702, it is determined whether the key input by the operator is the system dictionary conversion key 905 or the user dictionary conversion key 911. If the key is the system dictionary conversion key 905, in process 704, DICMODE is set to O, and the user dictionary conversion key 911 is set to O. If so, DIC in process 706
Set MODE to 1. DECM set here
ODE is a memory for determining whether to perform conversion processing using the system dictionary or user dictionary when the conversion key 903 is input.

Next, the operator enters the reading characters, enters the conversion key,
or a selection key 909 for instructing to change to another candidate because the conversion result is not the candidate intended by the operator; a system dictionary conversion key 905 or a user dictionary for the operator to perform the conversion process again using another dictionary after the conversion process; Kana-kanji conversion process 9 that starts when the conversion key 911 is input
The operational flow of o is shown in FIG.

First, when the operator inputs a reading character and inputs the conversion key 903, the process passes through processes 402, 406 and 410, and in process 412 it is determined whether DICMODE is O or 1. If DICMODE is O, in process 408, Kana-Kanji conversion processing is performed using the system dictionary, and DICMO
If DE is 1, in process 414, a kana-kanji conversion process is performed using the user dictionary. In the kana-kanji conversion process, the input reading character string in the temporary memory buffer is used to search the system dictionary or user dictionary in order from the first input reading character, and the part of speech of the searched word is used to test the connection with the preceding and following words. Repeat these steps to create Kana-Kanji conversion candidates.

This kind of kana-kanji conversion process is performed, for example, in Japanese Patent Application Laid-open No. 60-1
It is disclosed in Japanese Patent No. 89565. A specific example of data formed as a kana-kanji conversion candidate in the example of FIG. 8 is shown in FIG. The conversion candidates adopt a network-like data structure to prevent data duplication, and store the notation, its corresponding reading, and part of speech in this data structure, thereby reducing storage capacity. As a method of selecting the optimal candidate from the created network, for example, as shown in FIG. , and store it in the conversion candidate display buffer as the conversion result.

The likelihood here refers to the number of clauses multiplied by weights that take into account parts of speech and frequency of occurrence, and the smaller the number, the higher the likelihood. Weight 1 for verbs, 0 for formal nouns, auxiliary verbs, adjunctive words, etc.
．． 1. Prefixes and suffixes are treated as semi-independent words and given a weight of 0.5. In the case of the example in Figure 9, the 10th
As shown in the figure, "Your company de school ni line (") is stored in the conversion candidate display buffer. Also, as shown in Figure 10, the candidate is stored so that the operator can modify the kana-kanji conversion result created by the system to the candidate intended. Words that can be changed are stored in a correction candidate buffer in order.

Once the conversion candidate display buffer and modification candidate buffer have been set, the next step is to convert the part of the display character string stored in the conversion candidate display buffer, cut out from the dictionary, into the input pronunciation character and the display character string, and further convert the parts of speech to the above. For example, in the case of the example shown in Fig. 9, user dictionary registration data (hereinafter DICD
ATA). After the process 416 is completed, the FLG is set to 1 in a process 418, and the character strings set in the conversion candidate display buffer and the correction candidate buffer are displayed on the display unit 4 in a process 420, as shown in FIG. 17, for example.

If the kana-kanji conversion result displayed on the display unit 4 is not the candidate intended by the operator, a selection key 909 is used to request a change in the conversion candidate. When the operator inputs the selection key 909, in process 404 the conversion candidate display buffer is modified based on the selected candidate, and in process 416 the DICDA
Modify TA, DICCNT. Process the result 420
is displayed on the display section 4. For example, in the case of conversion as shown in FIG. 17, the "company" part is different from the candidate intended by the operator, so it is modified to "train" using the selection key 909. If “train” is selected, process 41
In step 4, a conversion candidate display buffer is set as shown in FIG. 12 using FIG. 9, and in step 416, DICDATA is updated as shown in FIG.

If the 50-on key 901 or the editing work key 913 is input in the state shown in FIG. 12, the DICDA in FIG.
Register the TA in the user dictionary.

With DICDATA in FIG. 12 registered in the user dictionary, input the user dictionary conversion key 911 to convert DICMO.
When DE is set to 1, the input shown in FIG. 8 is performed again, and the conversion key 903 is input, processing 402, 406, and 410 is performed.
In step 412, it is determined that user dictionary conversion is to be performed, and in step 414, a network data structure as shown in FIG. 13 is created, and a conversion candidate display buffer and a correction candidate buffer are created. “Kisha” as shown in Figure 13
There is only one conversion candidate for ``train'', and the conversion candidate for ``i'' is also one for ``row'', so only the candidates intended by the operator are displayed, as shown in FIG. Furthermore, creation of a network-like data structure becomes simple and conversion processing can be performed quickly.

Next, with DICMODE set to 1, as shown in FIG. 14, input "kisha to hanasu" and press the conversion key 903. As shown in the figure, "Train train" is output as a conversion candidate. In such a case, when the operator inputs the system dictionary conversion key 905, processing 4 is executed.
02° 406, system dictionary conversion is performed in process 408, a network data structure shown in FIG. 15 is created, a conversion candidate display buffer and a modification candidate buffer are created as shown in FIG. Redisplay as shown in Figure 19. Here, by selecting and confirming "Reporter" using the selection key, it is possible to create a document, and at the same time, it is possible to newly register "Reporter" in the user dictionary. In this way, when performing Kana-Kanji conversion using the user dictionary, if the requested candidates do not exist, the system side performs the Kana-Kanji conversion process using the system dictionary by simply inputting one key, and the selected candidates are selected by the user. The operator's operability is greatly improved because the data is registered in the dictionary.

Finally, FIG. 7 shows the operational flow of the user dictionary registration process. In process 502, the DIC that manages the user dictionary
PC) Register DICDATA as many as DICCNT from the location indicated by INTER. Next, in process 504 DICPOINTER is updated, and in process 506 YOM
Set I CNT to 0.

As an example, a method has been described in which words used in the user dictionary are registered in order, but the structure of the user dictionary is not particularly limited. Further, regarding the system dictionary conversion key and the user dictionary conversion key, it is also possible to combine two keys into one, or it can be realized by a method in which a display is displayed on the display section 4 and the selection is made. Therefore, there are no particular limitations as long as information on system dictionary conversion and user dictionary conversion can be provided to the system.

〔Effect of the invention〕

As described above, according to the present invention, a user's own user dictionary can be automatically created from a large-scale system dictionary specific to the system provided by the manufacturer, and
When a document is created using a user dictionary, there is less possibility that words that are unnecessary for the operator will be output, so that the operator can work more efficiently. Further, when the candidate intended by the operator does not exist, the desired candidate can be retrieved from the system dictionary with a single operation, and by confirming the candidate, it is possible to newly register the candidate in the user dictionary.

Note that the present invention is configured to sequentially convert kana character strings that are input in order using a system dictionary or a user dictionary. It is also effective for devices that input data.
