Abstract

PURPOSE:To select a proper dictionary in a KANJI (Chinese character) converter provided with a basic dictionary and plural field dictionaries. CONSTITUTION:When phonetic symbol string is inputted, an input part 1 segments the reading code of a morpheme corresponding to the phonetic symbol to sent to a dictionary retrieving part 6. A dictionary usage recording part 82 records the using time of each dictionary. A dictionary selection part 90 decides the retrieving order by giving priority to the dictionary of more using times in the respective dictionaries 70 and 71, which is recorded in the dictionary usage recording part 82. A dictionary retrieving part 6 retrieves the inside of each dictionary corresponding to the priority order by setting the reading code sent from the input part 1 as a retrieving key and detects all the corresponding homophones and word candidates. A character conversion part 5 makes a display part to display the detected homophones and word candidates, makes a user to confirm right conversion and sends the code of a dictionary registering the homophone and word which are judged to be right to a dictionary managing part 81. The dictionary managing part 81 updates the dictionary usage recording part 82.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kanji conversion device, and more particularly to a kanji conversion device that appropriately selects a basic dictionary and a plurality of field-specific dictionaries according to an input document.

[0002]

2. Description of the Prior Art Prior to describing the present invention with conventional techniques and examples, important words and terms will be explained and defined. The main object of the present invention is a character conversion device such as a Chinese word processor or a Japanese word processor. For this reason, the "phonetic character" that is the target of the kanji conversion input by the user or the application program described in the present specification means a pure phonetic character such as an alphabet and a "kana" in Japanese. Not only phoneme characters such as ", but also ideographic characters such as Arabic numerals, other onmon (Hangul characters) in Korean, syllabic symbols in Chinese, such as the tone marks"-"," / ", and" V ". , "And symbols similar to" \ "(these are substituted by similar symbols for the convenience of input by the electronic information processing system). In addition, "Kanji" which is the result of Kanji conversion is not only pure "Kanji" such as "ho" and "patent law", more accurately "ideographic characters" and words consisting only of kanji In addition to wrapping words, phrases, and syllables in which kanji and kana are mixed, such as "I love you" in a word, it also includes other symbols such as "no".

Next, there are cases in which a kanji character such as "string" such as "phonetic character string" is used. However, as a practical matter, even one kanji character is designated as a conversion target in a plurality of phonetic characters. This is due to the fact that there are many cases where the conversion result is often a plurality of kanji, and there is no particular limitation. That is, the case of one is also included. Also, “word”, “word”, etc. may be composed of only one character.

Further, the "field" in the "field-specific dictionary" is a concept that can be said to be "a group of mutually related words, phrases, etc.", and "Buddhism", "communism", Not only classification in academic and practical fields such as "law", "military", "diplomacy", but also "Ming dynasty", "Kan dynasty", "Before Zhou"
Division in equal age, division in languages such as “Mandarin”, “Shanghai”, “Japanese”, “Korean”, and other special names such as “individual name”, “entertainer”, “Chineseized foreign language” Including classification, etc.

The kanji reading input method is, for example, to input a phonetic character representing kanji reading through a keyboard,
With reference to the dictionary, the morpheme reading code is cut out and character conversion processing is performed, and the input phonetic character string is converted into a character string. However, when the dictionary contains many letters and words, it is easy to cut out the morpheme reading code, and because the number of homophones and words increases and the search speed of the dictionary decreases, The efficiency of kanji conversion is also poor. For this reason, in general, dictionaries should be divided into a basic dictionary that stores (collects and stores as-usable) everyday words and general words, and a field-specific dictionary that stores words used in each field. Is done. In this case, the user selects the category dictionary according to the category of the document to be input.
However, when the document to be input spans several fields, the user needs to constantly switch the field-specific dictionary, resulting in poor input efficiency. Conventionally, as a kanji conversion device having a function of switching the field-specific dictionary, there has been one such as disclosed in Japanese Patent Laid-Open No. 80863/1992. FIG. 5 is a block diagram of an example of such a kanji conversion device. In the figure, 1 is an input unit and 2
Is a control unit, 3 is a display unit, 4 is a text buffer, 5 is a character conversion unit, 6 is a dictionary search unit, 70 is a basic dictionary, and 71 to 7n are field-specific dictionaries. 8 is a dictionary selection order designation unit, and 91 and 92
Is a dictionary group holding unit. The dictionary group holding units 91 and 92 hold the basic dictionary 70 and the plurality of field-specific dictionaries 71 to 7n in the search order according to the contents of the document created by the user. The input unit 1 has a keyboard for inputting a kana character string and the like, and for performing an operation of switching the dictionary group holding units 91 and 92 at the time of kana-kanji conversion. The text buffer 4 holds the input phonetic character string and the converted Chinese character string. The display unit 3 has a CRT or the like and displays the contents of the text buffer 4 and the like. The dictionary selection / order designation unit 8 uses the basic dictionary 7
A process of selecting a plurality of dictionaries to be searched from 0 and a plurality of field-specific dictionaries 71 to 7n according to the contents of a document to be created according to the search order and registering them in the dictionary group holding units 91 and 92 is performed. The dictionary search unit 6 searches the dictionaries held in the dictionary group holding units 91 and 92 to convert the input kana character string into a kana-kanji mixed character string. The kana-kanji conversion control unit 5 converts the kana-character string input based on the dictionary searched by the dictionary searching unit 6 into a kana-kanji mixed character string. The control unit 2 controls the input unit 1, the text buffer 4, the display unit 3, the dictionary selection, the order designation unit 8, the kana-kanji conversion control unit 5, and the like.

The operation of the Kanji conversion apparatus having the above-structured field-specific dictionary switching function will be described below. The user may have registered the kanji and words to be searched according to the content of the document to be created from the basic dictionary 70 and the plurality of field dictionaries 70 to 7n by the dictionary selection / order designation unit 8. A plurality of high dictionaries are selected, the search order is also specified, and the results are registered in the dictionary group holding units 91 and 92. For example, when creating a document related to information processing, the dictionary group holding unit 92 stores a dictionary (a basic dictionary and, for example, an information processing term dictionary according to the content of the document) to be searched in a normal conversion in the dictionary group holding unit 92. The dictionaries (for example, a surname dictionary, a place name dictionary, and a basic dictionary) to be searched when converting to proper nouns are registered in this priority order. The kana character string input from the input unit 1 is held in the text buffer 4 and displayed on the display unit 3. In the kana-kanji conversion processing, the kana-kanji conversion control unit 5 causes the dictionary retrieval unit 6 to store the dictionary groups 91 and 9.
While searching the dictionary registered in 2, the kana character string is converted into a character string mixed with kana and kanji. Then, the kana character string in the text buffer 4 is replaced with the converted character string and displayed on the display unit 3. At this time, if the above dictionaries are registered in the dictionary group holding units 91 and 92, the dictionaries registered in the dictionary group holding unit 91 are searched in the order of registration during normal Kana-Kanji conversion. Information processing terms are output earlier than general terms. If a proper noun such as a person's name appears in the document, the dictionary group switching key of the input unit 1 is operated to switch the dictionary group to be searched to the dictionary registered in the dictionary group holding unit 92. When the dictionary switching key is operated again, the dictionary group holding unit 91 is returned to. As described above, the dictionary groups are switched by operating the dictionary group switching keys.

When there are a plurality of kanji strings or words having the same pronunciation, a procedure for displaying the kanji strings or words in the order of priority or at the same time on the display unit to identify what the user intends, and for that purpose The structure, the procedure and structure for displaying the kanji string specified by the user at a predetermined position in the text currently being created, and the kanji conversion that integrates the phonetic character string consisting of many input phonetic characters. The procedure necessary for classifying as an object, for example, the longest matching method and the configuration therefor is the same as or basically the same as that of a normal Chinese word processor or a Japanese word processor, and is not directly related to the gist of the present invention. do not do. Therefore, illustration and description thereof are omitted.

[0008]

However, the above-mentioned prior art apparatus has the following problems. First problem. It is necessary to manually select a dictionary according to the contents of the input document and switch the field-specific dictionary. However, the correct switching of the field-specific dictionaries puts a heavy burden on the user. Also, if the field of the dictionary registered in the dictionary group holding unit is not correct, the morpheme reading code (phonetic character string) that is the target of Kanji conversion by the longest matching method, etc. is not correctly extracted and converted. Therefore, the conversion efficiency of Kanji will be poor.

Second problem. If the input document contains words in several fields and therefore it is necessary to change the selection of fields intricately, it is a great trouble for the user to switch the field-specific dictionaries. The present invention has been made in view of the above problems, and an object thereof is to provide a kanji conversion device that appropriately and automatically selects a field-specific dictionary.

[0010]

In order to achieve the above object, according to the invention of claim 1, an input unit is provided which cuts out a morpheme reading code corresponding to the input phonetic character string and sends it to the dictionary search unit. In a kanji conversion device having a dictionary unit composed of a basic dictionary and a plurality of field-specific dictionaries and a display unit, a dictionary use recording unit for recording the number of times of use for each dictionary,
A dictionary selection unit that determines the search order of each dictionary by giving priority to the one that has been used many times recorded in the dictionary use recording unit,
Using the phonetic symbols sent by the input unit as a search key, each dictionary is searched according to the search order determined by the dictionary selection unit, and all the homophones, word candidates and the homophones and word candidates corresponding to the phonetic symbols are searched. For each user, the code of the registered dictionary for each field is extracted and sent to the character conversion unit, and the homophones and word candidates searched by the above dictionary search unit are displayed on the display unit and are correct for the user. Based on the character conversion unit that confirms the conversion and sends the code of the dictionary with the correct homophones and words to the dictionary management unit and the dictionary code sent from the character conversion unit, The kanji conversion device is characterized by having a dictionary management part that updates the number of times of use of each dictionary recorded in the dictionary use recording part in a predetermined procedure.

According to a second aspect of the present invention, when updating the record of the dictionary use recording unit, the dictionary management unit determines the number of times of use of a predetermined number of the plurality of dictionaries in which the number of times of use is recorded. When the threshold is reached in advance, a constant value is used from the number of uses for dictionaries that have not reached that threshold until the end of the Kanji conversion. The kanji conversion apparatus according to claim 1, wherein the dictionary is set to be removed or set to 0, and the dictionary that has been used up to that time or has become negative as a result of the removal is not used.

According to another aspect of the present invention, when the dictionary search unit succeeds in searching for homophones and word candidates corresponding to the phonetic symbol in a predetermined number of dictionaries, the search is performed at that stage. The kanji conversion device according to claim 1 or 2, wherein only the homophones and word candidates that have succeeded are displayed on the display unit for the user to confirm the correct conversion.

[0013]

With the above structure, in the invention of claim 1,
The dictionary use recording unit records the number of times of use for each dictionary (stores in a form that changes according to the use situation). The dictionary selection unit gives priority to the dictionary used most times in each dictionary recorded in the dictionary use recording unit, and determines the search order. The dictionary search unit searches each dictionary according to the search order determined by the dictionary selection unit, using the reading symbols sent from the input unit as a search key, and stores all the homophones and words stored corresponding to the reading symbols. Candidates (in this stage, they are candidates for characters and words intended by the user) and homophones, and for each word candidate they are registered (semi-permanent or permanent storage in advance) The dictionary code is taken out and sent to the character conversion unit. The character conversion unit displays the homophones and word candidates searched by the dictionary search unit on the display unit, and prompts the user to confirm the correct conversion. To the dictionary management section. The dictionary management unit updates the number of times of use of each dictionary recorded by the dictionary use recording unit according to a predetermined procedure based on the dictionary code sent from the character conversion unit.

In the invention of claim 2, when updating the record of the dictionary use recording unit, the dictionary management unit predetermines the number of times of use of a predetermined number of the plurality of dictionaries recorded for use. Threshold is reached,
For a dictionary whose usage count has not reached the specified value up to that point, or until the end of a set of kanji conversion, a certain value is subtracted from the usage count, and as a result, the usage count up to that point is 0. Or set it to unused for negative dictionaries.

According to another aspect of the present invention, the display unit is configured such that the dictionary search unit uses homophones corresponding to phonetic symbols in a predetermined number of dictionaries,
When the word candidate search is successful, regardless of whether or not another dictionary is searched, only homophones and word candidates that have been successfully searched at that stage are displayed for the user to confirm the correct conversion. To be displayed on the department.

[0016]

EXAMPLES The present invention will be described below based on examples. (First Embodiment) This embodiment relates to the inventions of claims 1 and 2. FIG. 1 is a block diagram of an embodiment of a kanji conversion device according to the present invention. In the figure, 1 is an input unit, 2 is a control unit, 3 is a display unit, 4 is a text buffer, 5 is a character conversion unit, 6 is a dictionary search unit, and 70 is a dictionary search unit. Reference numerals 71 to 7n are field-specific dictionaries, 81 is a dictionary management unit, 82 is a dictionary use recording unit, and 90 is a dictionary selection unit. Control unit 2,
The configurations and principles of the display unit 3, the text buffer 4, the basic dictionary 70, and the field-specific dictionaries 71 to 7n are the same as or similar to those of the related art, and therefore description thereof will be omitted unless related to the present invention. Keep it simple. The basic dictionary 70 stores basic words corresponding to the phonetic symbols as search keys. The dictionary usage recording unit 81 records the value of the number of times of use or the value of the non-use symbol "X" using the dictionary code as a search key, and records the value of the number of times of use in order from the smallest value to the smallest value. To do. The field-specific dictionaries 71 to 7n store words unique to each field for a plurality of fields, and use the phonetic symbols as search keys to store words corresponding to the fields. The dictionary selection unit 90 refers to the number of times of use and the order of arrangement of the field-specific dictionaries recorded in the dictionary use recording unit 82, determines the field-specific dictionaries to be used and the search order thereof, and instructs the dictionary management unit 81. In this way, the field-specific dictionary to be searched and the search order are determined. The dictionary search unit 6 extracts all homophones and word candidates corresponding to the field-specific dictionary designated by the dictionary selection unit 90 and the search order using the phonetic symbol as a search key. The dictionary management unit 81 determines the number of times of use of each dictionary recorded in the dictionary use recording unit 82 based on the dictionary code for each Kanji and word in the character string determined to be the correct conversion by the user. Update the order of recording and array. The character conversion unit 5 converts the input phonetic character string into a conversion candidate Kanji string or word through the dictionary search unit 6 and displays it on the display unit 3, and then displays the Kanji string or word intended by the user. Is sent, and the code of the dictionary in which the correct kanji string and word are registered is sent to the dictionary management unit 81. The display unit 3 sequentially displays the homophones and word candidates searched by the dictionary search unit 61, and further displays a kanji string and a word that are correct by the user at a predetermined position of the sentence being created.

2 and 3 are operation flow charts of this embodiment. The basic operation flow will be described below with reference to FIG. (S21) The user inputs a phonetic character string to be converted into a set of Kanji characters from the input unit. In the specific example shown later, phonetic character strings forming seven syllables are input.

(S22) The input unit cuts out a morpheme reading code corresponding to a word to be converted as a unit from the input phonetic character string. It should be noted that in the specific example described later, two or three syllables form a word. (S23) The dictionary search unit refers to the number of times of use recorded in the dictionary use recording unit, searches the field-specific dictionary or the basic dictionary, and displays the corresponding character or word candidate. In this case, if it is a search for all the reading codes of the morphemes that have not been converted or have been erroneously converted, character conversion is performed on the morphemes. FIG. 4 conceptually shows the recorded contents of the number of times of use of the dictionary use recording unit.

(S24) The user refers to the display unit to determine whether all the converted Kanji characters are correct. If there is an inaccurate one, it is pointed out, and the process returns to (S23) in order to perform a search again with reference to the reading code of the morpheme or the morpheme to be converted that includes the morpheme. If not, go to (S25). (S25) The content of the dictionary use recording unit is updated with reference to the dictionary code of the dictionary including the kanji and words that are considered to correspond correctly to the morpheme reading code. The detailed operation flow for the update will be described later in detail.

(S26) The correctly converted Chinese character string is displayed at a predetermined position of the sentence being created. Next, the operation flow of the dictionary management unit will be described with reference to FIG. (S301) The threshold value TH and the total number h of kanji-converted words included in the phonetic character string input as a group of kanji conversion targets are set.

(S302) The kanji corresponding to the word determined to be the correct conversion and the dictionary code of the word are sequentially stored in the temporary storage device. Therefore, the variable A [J] is set.
Here, J = 1, 2, ..., H, and the content of each A [J] is a dictionary code. (S303) The start value of the variable J is set to 1. (S304) It is determined whether J> h. If not J> h, go to (S305).

(S305) The value of A [J] is used as a search key to refer to the dictionary use recording unit to extract the number of times the dictionary is used, and CNT is stored as a variable. Note that CNT = X
If this is the case, the dictionary is not used, and such a case cannot occur. (S306) When 1 is added to CNT, the process goes to (S307) above.

(S307) It is determined whether CNT> TH. If CNT> TH, an update process will be performed, so the process proceeds to (S308), and if not CNT> TH, the process proceeds to (S310). (S308) The constant value D is subtracted from the number of times the dictionary has been used, which is currently recorded in the dictionary use recording unit. Then, (S3
Go to 09).

(S309) The result is newly set as the number of times of use. For a dictionary whose use count is 0 or negative, the use count is set to X. Go to (S310). (S310) A [J] is used as a search key to find a corresponding dictionary, and the new CNT value is recorded in the dictionary use recording unit. (S311) After adding 1 to J, the process returns to (S304) to perform the same process for the next kanji and word.

(S312) Based on the number of times of use, the recording of the number of times of use of the dictionary use recording unit and the updating of the arrangement order are completed.
FIG. 4 is a diagram conceptually showing the storage contents of the dictionary use storage unit. In this figure, the first column shows the dictionary code for each field, the second column shows the number of times of use, and these are arranged in descending order of the number of times of use from top to bottom. Has been done. In the figure, the number X of times of use indicates that the field-specific dictionary is not used.

In the present embodiment, the basic dictionary is searched for in the first priority, which is not subject to the operation according to the present invention, and the threshold value of the dictionary management unit and the number of times of use are compared. The predetermined number is 1. As a practical matter, the frequency of use of the basic dictionary is higher than that of any field-specific dictionary.
The threshold number and the number of times the dictionary is used are 2
Is substantially the same as

However, in this case, since only the frequency of use of the basic dictionary increases, the number of records of the number of times of use tends to increase inevitably. Therefore, it is necessary to take measures for the processing such as setting an upper limit. Next, taking the dictionary use storage unit shown in FIG. 4 as an example, how the dictionary management unit shown in FIG. 3 changes will be specifically described by the operation flow.

Now, "lian2jyuen1zuen1shou3guo2ji4fa3
When the phonetic character string “” is input, first, the number of syllables to be composed is first, and secondly, the input order is prioritized and the syllable to be converted into Kanji is extracted. The result of doing is "lian2jyuen1 zu
en1shou3 guo2ji4fa3 ”. Then, the phonetic character string is converted into a character string "Union-compliant international law" by referring to the field-specific dictionary and the basic dictionary. The related dictionary codes are 5 (military) for "Union", 0 (basic dictionary) for "compliance", and 7 (law) for "international law". In the description of the operation flow shown in FIG. 3 above, the content of each A [J] is only “code of field-specific dictionary”, and there are nine types of field-specific dictionaries in total, so in (S302) The value of A [J] is from 1 to 9. Here, the dictionary code is "0"
Indicates a basic dictionary.

Next, the processing flow of the dictionary management unit in FIG. 3 will be described. (S301) Since the number of kanji strings and words that have been subject to kanji conversion as a unit in the transition of the series of phonetic character strings is three, h = 3. For ease of explanation, the value of TH is set to 137 here. (S302) A [1] = 5, A [2] = 0, A [3] = 7 (S303) The variable J is set to 1.

(S304) Since J <3 = h, (S304)
Go to 305). (S305) Using the value 5 of A [1] as a search key, the usage count 137 is retrieved from the dictionary usage recording unit and stored in the CNT. (S306) Add 1 to CNT to obtain 138. (S307) Since CNT> TH, the process goes to (S309).

(S308) The dictionary use recording unit has a fixed value of 10
Will be updated as follows. (However, only the updated part in FIG. 4 is shown. This is also the case when the updated contents are shown later.) 5 (military) 138 3 (economy) 597 (law) 18 (accounting) X or more Go to (S310).

(S310) A dictionary is obtained by using the value 5 of A [1] as a search key, and the current value of CNT is recorded in the dictionary use recording unit as the number of times of use. (S311) 1 is added to J to make 2 and then (S30)
Return to 4). The same processing operation is performed when J = 2 and J = 3. The contents of the dictionary use recording unit in this state are shown below in order.

J = 2: 5 (military) 139 3 (economy) 59 7 (law) 18 (accounting) X J = 3: 5 (military) 139 3 (economy) 59 7 (law) 28 (accounting) X In this case, J = 4 in (S304), and since 4> 4, go to (S312).

At (S312), the process of recording the number of times of use and changing the arrangement order accordingly is terminated. In this case, the finally used field-specific dictionaries and their arrangement order are the same. (Second Embodiment) This embodiment is the same as the first embodiment described above.
The dictionary management unit is the same as the first embodiment except that when the number of times of use of a certain field-specific dictionary reaches a predetermined threshold value, the number of times of use up to that point is reset to 0.

For this reason, the operation and the like of each part will be described after the configuration diagram is illustrated, and the description of the same operation in the process flow chart will be omitted, and only the operation and the process flow unique to this embodiment will be described. In the previous (S307), the dictionary management unit sets the values of all the field-specific dictionaries to 0. Therefore, the contents of the dictionary use recording unit are as follows.

5 (military) 0 3 (economy) 0 7 (law) 0 8 (accounting) 1 Similarly, in (S311), when the operation of J = 2 is completed, the contents of the dictionary use recording unit are as follows. become that way.

At the stage when the operation of 5 (military) 1 3 (economy) 0 7 (law) 08 (accounting) X J = 3 is completed, the following is the same.

5 (Military) 1 3 (Economy) 0 7 (Law) 18 (Accounting) X Under the number of times of use, the dictionary selection unit changes the arrangement order of the dictionary for each field. Therefore, the final result is as follows.

5 (military) 1 7 (economy) 1 3 (law) 0 8 (accounting) X When compared with the first embodiment, the number of uses of all field-specific dictionaries is set to 0 in this embodiment. Since it is set again, it is advantageous when the number (types) of field-specific dictionaries that are supposed to be used from the beginning is large. (Third Embodiment) This embodiment relates to the invention of claim 3.

The basic structure of this embodiment is the same as that of the first embodiment. Therefore, the configuration diagram and the like are omitted. However,
The dictionary selection unit has a built-in counting unit, and this counting unit calculates the number of dictionaries to be searched for each reading symbol as a search key,
If the search is successful within this predetermined value, the character conversion unit is notified of this. Further, the character conversion unit that has received this notification causes the homophones and word candidates retrieved at that stage to be displayed at a predetermined position on the display unit for confirmation of correct selection by the user. For this reason, it is different in that it has a temporary storage unit for holding the homophones and word candidates detected by searching a dictionary having a lower priority thereafter without displaying them on the display unit.

However, the configuration of the counting unit, the signal (trigger signal) generating unit and the temporary storage unit that triggers the character converting unit to exert its action at an intermediate stage by the notification from the counting unit is, as it were, known technology. Therefore, the description of the contents is omitted. When compared with the previous example, in this example,
In the middle of the search, homophones with high accuracy and only word candidates are displayed as the user's intended kanji and word confirmation target,
Since the selection is made, the speed of Kanji conversion is improved.

Although the present invention has been described above based on the embodiments, it goes without saying that the present invention is not limited to the above embodiments. That is, for example, the following is also included in the present invention. (1) In the first and second embodiments, X is added to the display of the field-specific dictionaries that are not used, but other arbitrary flags,
Adopt means. Similarly, subtraction of a fixed value from the number of times each category dictionary is used can be calculated for each word (A in the specific example).
[J], J = 1, 2, 3) Instead of doing it, after additionally correcting the number of times of use for each field dictionary of all the words that have been subjected to a set of kanji conversion (specific example (Corrected for all "Legendary", "Compliance", and "International law"), and compared with the threshold value in order, and if the number of times of use reached the threshold value even in one field dictionary, We try to remove a certain amount. (2) The dictionary use recording unit is updated even when the value is larger than a certain threshold value by accumulating the number of updates for each dictionary using the control register. (3) In the inventions of each claim, the basic dictionary is excluded from the action of the dictionary use recording unit, the dictionary selecting unit, the dictionary managing unit, and the dictionary searching unit, or the action is excluded by the user's intention. A function is added that allows the field dictionary to be designated as the basic dictionary.

Similarly, a function is added so that the user can exclude the specific field-specific dictionary from the beginning. In addition, the predetermined number in the invention of claim 2,
A function that can change the threshold and constant value is added. (4) The field-specific dictionary has a function that can be attached and detached. (5) When it is difficult to display all the homophones etc. searched by the dictionary search unit on the display unit by the character conversion unit because it is difficult to display all of them without changing the frequency of use Functions such as displaying all from one at a time by displaying the most frequently used ones in large size and the most frequently used ones in small size are added. (6) A device capable of exerting learning ability is added to each of the basic dictionary and each field dictionary. (7) The recorded content itself of the dictionary use recording unit is recorded in a separate device and can be called and switched as needed. As a result, depending on the field of the document to be created, the experience of using the previously created document in the same field can be reflected in the document currently being created, and with the same word processor, etc.
Documents in various fields can be created efficiently. (8) For convenience of manufacturing, one constituent element (requirement) described in the claims is physically and mechanically made into a plurality of objects, or conversely, a plurality of constituent elements is made into one object, or These are appropriately combined. (9) When homophones and word candidates are not detected, a message indicating this fact is displayed to the user, and a selection mechanism for automatically activating a field dictionary that is not used is added. Has been done.

[0044]

As described above, according to the present invention, the following effects are exhibited. (1) It is not necessary to manually select a field-specific dictionary, and the efficiency of Kanji conversion is improved for the creation of documents containing words and Kanji in many fields. (2) Learning abilities according to the experience of using the field-specific dictionary can be obtained, the necessary field-specific dictionary is preferentially selected, and unnecessary dictionary is closed, so that the dictionary search speed is improved.

(3) By always holding only the necessary field-specific dictionaries, the candidates for homophones and words searched and listed as kanji conversion candidates are reduced. Therefore, not only the accuracy rate and speed of character conversion are greatly increased, but also the eyestrain of the user is reduced.
