Description

DETAILED DESCRIPTION OF THE INVENTION [Outline] Regarding a frequency changing method of a character processing device that outputs a plurality of candidate characters corresponding to an input “reading”, there are two types of frequency information according to a display format and frequency information for each conversion candidate character. With the aim of providing a frequency changing method of a character processing device in which both the display format and each conversion candidate character are taken into consideration, the dictionary data unit includes a word dictionary having frequency information for each conversion candidate character, A dictionary search means for searching the word dictionary by inputting "reading" is provided, which includes the latest designated format information for a specific character type having a plurality of display formats and a display format dictionary having frequency information for each display format. A specific character type detecting means for detecting that the specified character is the specific character type, and a frequency changing means activated when the specific character type is detected, the frequency changing means being the latest specified format information of the display format dictionary. By combining the frequency information for each display format and the frequency information for each conversion candidate character, the frequency of each candidate character is changed, and the candidate characters are output in the order corresponding to the result.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frequency changing method of a character processing device that outputs a plurality of candidate characters corresponding to an input "reading".

In recent years, word processors, workstations, and the like have been widely used as information processing devices capable of inputting Japanese, and their functions have been gradually enhanced.

Conventionally, when displaying a plurality of character strings (Kanji, etc.) that are applicable conversion candidates when "Yomi" is input, the order of output as candidate characters based on the frequency actually selected up to that point is displayed. A control method is used. on the other hand,
Among the types of characters, for example, there are character types that have many display formats for one “reading” such as numbers. For example, “1” for “reading” “1”,
There are many change candidate characters with different display formats such as "1)", "(1)", "I", "", etc., and consider such character types (there are various alphabets, symbols, etc. in addition to numbers). Then, a method of changing the frequency of the change candidate characters is also proposed. However, these methods are inconvenient for the user because the frequency change management of either the frequency priority for each character or the frequency priority for each display format between the same character types is performed.

[Prior Art] FIG. 5 is an explanatory diagram of Conventional Example 1, and FIG. 6 is an explanatory diagram of Conventional Example 2.

The system of Conventional Example 1 is a system widely used in devices having a Japanese character input function such as a word processor. As shown in the figure, the read byte length, the abbreviated read byte length, and the read word length are provided as the internal structure 51 of the word dictionary in the dictionary data section.
And the like, character usage frequency information 511 for each character is stored.

B. The flow of Kanji conversion using a dictionary such as A. The outline of the content is shown, and when "Yomi" is input (step 52), the character usage frequency information is extracted from the conversion candidate character group and compared, and the candidate characters are rearranged and displayed in the order of frequency (step). 53). On the other hand, when one conversion candidate character type is selected from an input device such as a keyboard (step 54), the frequency information of the designated character type is updated (step 55), and the same processing is executed until the input is completed. To be done. In this method, no consideration is given to the frequency of use of candidate characters having a plurality of different display formats as described above as character types, and only the frequency of each candidate character is used.

The method of Conventional Example 2 is a method that has frequency information for each display format of the same character type.
-4186)).

FIG. 6B. As shown in, each conversion candidate character corresponding to "reading" in the dictionary is provided with a display format identification number, and a table of frequency information (priority information) is provided corresponding to each display format identification number. .

In the example of the figure, two dictionaries 60 and 61 of "ichi" and "ni" are shown as "yomi". For each word in the dictionary, "0" is given to general kanji such as "position" and "city". Is added to the group of Chinese numerals (1, 2, etc.) and the identification number of "43" is added to the group of Arabic numerals (1, 2, etc.). The case where it is attached is shown. A table 62 of frequency information for each display format number is provided for each “reading” dictionary including such 60 and 61.

The flow of Kanji conversion in the case of having such a dictionary and table is shown in A of FIG. That is, when "Yomi" is input (step 63), the display format identification information is checked for the conversion candidate character in the corresponding dictionary (step 6).
4) The frequency information of the identification information of each display format is extracted and compared, and the candidate characters are rearranged and displayed in descending order of frequency (step 65). When one conversion candidate character is selected from the displayed characters (step 66), the frequency information of the designated character (display format information table 62) is updated (step 67), and this operation is performed until the input is completed. Repeated.

Explaining with a concrete example, when "ichi" is input as "yomi" in the kanji conversion and "one" is selected from the conversion candidate characters, the numerical value of the frequency (priority) of the identification number 44 is increased. After that, when "ni" is input as the "reading", the frequency of the identification number 44 is increased as the conversion candidate character and "2" is preferentially displayed.

[Problems to be Solved by the Invention] In the method of the conventional example 1 described above, when it is desired to uniformly specify the display format, a character having a desired display format must be selected from candidate character types for each character. There is a problem. On the other hand, according to the method of the second conventional example, even when selecting a character having a display format and designating another display format for a specific character, a desired character is selected from the candidate characters whose frequency is changed depending on the display format. There was a problem of having to select a character.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a frequency changing method for a character processing device in which both the display format and the conversion candidate character are taken into consideration in consideration of two pieces of the display format frequency information and the conversion candidate character frequency information. .

[Means for Solving the Problems] FIG. 1 is a principle configuration diagram of the present invention.

In the figure, 10 is a character processing device, 11 is a dictionary search means, 12 is a specific character type detection means, 13 is a frequency changing means,
14 is a means for rearranging candidate characters, 15 is an updating means, 16
Is a dictionary data section, 161 is a word dictionary containing frequency information for each conversion candidate character, 162 is a display format dictionary containing latest designated format information, and 17 is a work area.

The present invention is provided with a word dictionary having frequency information for each conversion candidate character in the dictionary data part, a display format dictionary having latest designated display format information and frequency information for each display format, and a display format for a "reading" input. When there are different conversion candidate characters, the frequency information of each conversion candidate character is calculated by adding the latest specified display format information of the display format dictionary and the frequency information for each display format, and the candidates are selected according to the rank of the calculated frequency information. Get and display the order of letters.

[Operation] When “reading” is input to the character processing device 10 of FIG. 1 and a conversion instruction is issued, the dictionary search means 11 is activated and the word dictionary 161 of the dictionary data unit 16 is searched. A word dictionary including frequency information of conversion candidate characters corresponding to "yomi" is detected. This word dictionary includes the address information of the display format dictionary 162 indicating that each “reading” is a specific character type having a plurality of display formats. The frequency information of the display format is taken out from the display format dictionary 162 into the work area 17 by the detection output from the specific character type detecting means 12, and the frequency changing means 13 is activated.

The frequency changing means 13 first extracts the frequency information of the corresponding display format of the work area 17 by using the latest designated character format information contained in the display format dictionary 162 of the corresponding specific character type using the above-mentioned address information, and the number thereof. And a certain number are added to and written in the frequency information of the display format of the work area to update.
Subsequently, new frequency information is calculated by adding the frequency information of each candidate character to the frequency information in the display format read in the work area 17 at a fixed ratio.

Next, the candidate character rearrangement unit 14 rearranges the obtained frequency information about the display format in frequency order, and outputs the candidate characters for display according to the rearranged result.
When the user selects a specific character for the displayed candidate character, the frequency information of the word dictionary 161 of the dictionary data unit 16 and the contents of the display format dictionary 162 are used by using the selected candidate character and its display format. (Latest designated format information and frequency information in each display format) is updated.

Thus, by associating the latest specified display format information of the display format and the frequency information of each display format with the frequency information of the corresponding conversion candidate character in the word dictionary, not only the display format frequency but also the conversion candidate character It is possible to output the candidate characters with a total frequency including the frequencies of.

[Embodiment] FIG. 2 is a block diagram of the dictionary data part of the embodiment, FIG. 3 is a processing flow chart of the frequency change of the embodiment, and FIG. 4 is a diagram showing a concrete operation example of the present invention.

In FIG. 2, the dictionary data section 20 shown on the upper left is a dictionary management information section 21, a word dictionary section 22, and a display format dictionary section 2.
3, the radical dictionary unit 24 and the like.

The word dictionary unit 22 therein stores the dictionary data related to each "reading" character, and its internal structure is secondly shown by an example of the dictionary data 221 of one "reading" character string.
As shown in the upper right of the figure. That is, dictionary data 2
21 is "reading byte length", "abbreviated reading byte length",
A structure in which "pointer to table of display format dictionary" and "conversion candidate character byte length" are provided after "reading", and then a plurality of data corresponding to each conversion candidate character are sequentially stored. Has become. For each conversion candidate character, "display format name", "conversion candidate character (code) string", and "character use frequency" data are provided.

Next, showing the internal structure of the display format dictionary section 23 of the dictionary data section 20, display format tables 231, 232 ... Are provided corresponding to respective character types such as “number”, “alphabet” ,.
The structure of an example of the display format table 231 of "number" will be described. First, the character type name, the latest designated display format information, and then the information for each display format are stored in sequence.
The information for each display format includes a display format name and its frequency. Explaining the example of the display format of "Number", the normal display format is "1", the circled display format is "", the display format with parentheses is "1"", the brackets are" (1) ", and the period is There are "1.", Roman numeral small letter "", Roman numeral capital letter "I" etc. The present invention can be implemented in a character processing device including such a dictionary data unit, a memory having a work area, a processing device that operates by a program, an input device such as a keyboard, and a display device such as a CRT display or liquid crystal. it can.

The processing flow of the embodiment of the present invention is shown in FIG.

In FIG. 3, "reading" is first input (step 31). When there is a signal indicating the completion of this "reading" input (or a key operation of "conversion"), the next step 32 is executed, the word dictionary section (22 in FIG. 2) is searched, and the corresponding dictionary data ( When 221) of FIG. 2 is detected, the "pointer to the table of the display format dictionary" therein is taken out (step 33). Next, it is determined whether or not the content of this pointer is "0". If "0", read this
The character type of indicates that it is an ordinary character (ordinary Chinese character that does not have multiple display formats), and if it is determined to be “0”, it is the same as the conventional method (see FIG. 5). Kanji conversion is performed.

When the pointer is not “0”, the display format dictionary section (23 in FIG. 2) is read with the content as an address, and the display format table of the corresponding character type (eg, 23 in FIG. 2) is read.
The frequency information for each display format of 1) is obtained in the work area (step 35). The frequency information for each display format of this work area is called a frequency information table.

Next, "Latest specified display format information" in the display format table
Then, a fixed number X is added to the value of the frequency information of the corresponding display format name in the frequency information table (step 36). This means that the frequency information of the recently designated (selected) display format is increased by a predetermined weight in the current selection of the display format.

Next, each frequency information (22 in FIG. 2) of all conversion candidate characters
(Stored in No. 1) are taken out and each is divided by a fixed number Y, and their quotient is added to the frequency information of each display format corresponding to the taken out conversion candidate character in the work area (step 37). This processing is based on the frequency information up to the present in the display format (the latest specified display format is added),
Means that the frequency of the conversion candidate character is substantially changed by the display format frequency by adding the frequency information up to the present corresponding to the conversion candidate character, and both frequencies are considered in ranking the conversion candidates. .

In this way, in the work area display format table, the frequency information newly changed for each display format is obtained.
Using the contents of the frequency table of the work area including this frequency information, the dictionary data (22 in FIG.
The candidate characters in 1) are rearranged (step 38). Then, using the rearranged results, candidate character strings are output from the display device in descending order of frequency (step 39).
In this way, the conversion candidate character string is displayed, and when the user who views it makes a selection, by detecting the selection instruction,
Conversion character selection is performed (step 40). As a result, the data of the selected conversion candidate character string is stored in a predetermined area (document data storage area) of the memory as in the conventional case.

Next, the value of the frequency information in the frequency change table of the display format of the designated character type is updated (step 41). This update is performed by adding a predetermined number (eg, 0.1) to the frequency of the display format name selected this time in the display format table (231 in FIG. 2).
Is added.

Next, the display format name selected this time is updated as the latest designated display format information in the display format table of the designated character type (step 42). Then, the frequency information of the selected candidate character in the corresponding dictionary data (221 in FIG. 2) of the word dictionary unit 22 is updated (step 43).

Next, it is judged whether the input is completed (step 44). If not completed, the process returns to step 31 and the same processing is executed.

In step 36, the value X to be added to the value in the frequency information table of the latest designated display format, and step 3
The value Y used when dividing each frequency information of the conversion candidate character in 7 can be set according to which of the frequency information and the frequency information of the conversion candidate character has priority according to the display format, and the relation thereof is With the added value X = 1 of the frequency information, Y
The case of changing is as follows.

(1) When it is desired to change the frequency by giving priority to the frequency information in the display format, Y> 1 may be selected as the value of Y.

(2) When it is desired to give priority to the frequency information for each conversion candidate character and change the frequency, a value in the range of 1>Y> 0 may be selected as the value of Y.

(3) When the weights of the display format and the frequency information of the change candidate character types are made equal, Y = 1 may be set.

Next, regarding a specific operation example of the present invention shown in FIG.
It will be explained in order of.

First, the number key “1” is operated, and then the “conversion” key is operated.

As a result, the word dictionary section 22 of the dictionary data section 20 shown in FIG. 2 is searched for the dictionary data (the format of 221 in FIG. 2) corresponding to “1” of the “reading” input, and the display format in that is searched. The contents of the numeric display format table (231 in FIG. 2) are retrieved using the table pointer (which stores the numeric display format table pointer). After this, the processing of steps 36 to 39 shown in FIG. 3 is performed.

The conversion candidate characters are displayed in the frequency order changed by the above processing.

When the user looks at this display and specifies "(1)", the contents of the dictionary data section for this character are updated by steps 41 to 43 in FIG.

After that, the character string “(1) Postcard ……” is input and a sentence is created.

After that, when the number key “2” is operated and the “Convert” key is operated, after the above operation, if the number of the frequently used display format is not used, enter “2”. Against
As shown in, candidate characters are displayed with “(2)” at the beginning.

′ Even if the above operation is performed, if there are other characters with high usage frequency (frequency information for each conversion candidate character or frequency information of display format) and the frequency of the display format of parenthesized numbers is low, As shown in the example of ', the character "" is displayed at the top, and "(2)" is displayed second.

Specify the character string you want to input from the above or'candidate characters.

EFFECTS OF THE INVENTION According to the present invention, as compared with the conventional one of the character information and the frequency information for each display format, by managing the two pieces of frequency information together, if the character types are the same, When different characters are input in the same display format, the operation of converting each character and selecting from the candidate character group can be omitted. Further, the frequently used characters can be displayed above the candidate character group regardless of the display format, and the operation of selecting can be simplified.
