Description

  The present invention relates to reading into a user dictionary and registering a phrase in a system that performs kana-kanji conversion in character input processing.

  When operating an information processing apparatus such as a personal computer or a mobile phone, a user often inputs a character string by operating a keyboard or a pointer on a screen. In particular, when inputting Japanese, it is necessary to input kana and convert it into a character string with kanji characters. Improvements have been made to devices that perform kana-kanji conversion.

  Basically, a kana-kanji conversion system in which anyone can easily and easily handle a kana-kanji conversion system has been realized by providing a word dictionary that corresponds to a kanji-character string to be converted corresponding to a kana character string.

  However, there are many cases in which different kanji character strings corresponding to the same kana reading are expected for each user, and are rarely used for normal use. There can be many character strings used only when targeting documents and documents.

  Storing all of these expected converted character strings in the word dictionary may be difficult to achieve in an information processing apparatus with limited resources. In particular, a small information processing apparatus with few resources is difficult and requires efficient kana-kanji conversion.

  Accordingly, word dictionaries are used by combining dictionaries according to several fields and uses according to the needs of users. User dictionaries are also used in which individual dictionaries are prepared and the correspondence between readings and character strings required individually is registered.

  In addition, when inputting English characters from the past, the application provides a function that displays spelled words that contain the input character string at the beginning of the character string in a list as candidates for the input character string. It had been. There is also provided a kana-kanji conversion system that displays a list of conversion candidate character strings including kana character strings input at the beginning of reading when inputting similar functions using Japanese kana-kanji conversion.

  This is because a predetermined number of character strings converted corresponding to the reading when Kana-Kanji conversion was previously performed and confirmed are stored, and the input character string is extracted from the stored character string included in the first character string of the reading. By selecting and instructing from the displayed list of conversion candidates, it is possible to perform kana-kanji conversion without inputting all of the readings (see Non-Patent Document 1).

  In this way, you can register the user's required readings and the words to be converted in the user dictionary in correspondence with each other, or list possible character strings from the conversion results without entering all the readings in the list. Japanese kana-kanji conversion has become easy to use.

  However, in order to register words in the user dictionary, it is necessary to set the character string of the phrase to be displayed after conversion to reading, and creating the character string of the phrase is troublesome work and hinders operability. It was.

For example, when registering a person name that is not contained in an existing dictionary such as “reading: wipe, phrase: Tomiki” in the user dictionary,
(Input) Tomi ↓
(Transformation) Wealth, wealth, Tomi ...
↓
(Final) Wealth ↓
(Input) ↓
(Conversion) Qi, Tree, Tree ...
↓
(Finalize) “Fuji” is created as a phrase by using an operation like a tree.

  Normally, when you enter “Fuki” without knowing whether the original character string you want to read is in the dictionary, the character strings such as “Fuki”, “Waki”, “蕗”, “Appendix” are converted. When it comes to know that it is shown as a candidate and is not registered in the dictionary, the character string “Fuji” is created by the above-described operation, and this character string and reading are created in the user dictionary registration means during document creation Registered using.

  However, when there is an unregistered character string in the dictionary as described above, there is an annoyance that it is necessary to use the word registration means, and the same operation is performed every time it is necessary without registering it in the user dictionary. Repeatedly creating new words.

  Therefore, when the reading of an unknown word is input and the target word is created as described above, this correction operation is detected and automatically corrected by taking the character string of the first presented unknown word as a reading. An idea of automatic word registration for registering a word / phrase obtained in this way in a user dictionary or the like has been proposed (see Patent Document 1).

  This is because when a character string of an unknown word is entered as a reading and is not registered in the word dictionary, the character string of the reading is divided and converted using the word dictionary, and the synthesized phrase is stored in the learning area. When storing and converting a character string, prior to searching the word dictionary, the words synthesized corresponding to the readings stored in this learning area are searched for as conversion candidates, and the number of times they are adopted is fixed. When it exceeds the value of, it is automatically registered in the word dictionary. As a result, when the same reading is input after the second time, the corresponding phrase is directly converted and output by searching the correspondence table stored in the learning area, and the number of times the converted phrase is adopted If the count exceeds a threshold value, it is automatically registered in the word dictionary, so that it has the effect of preventing the overflow of the learning area.

  Thus, the automation of word registration has been improved, but the word registration candidate is stored in the learning area and then stored in the learning area output corresponding to the input reading as a condition for word registration. Since the number of adopted words / phrases is used, there is a possibility that special terms that are temporarily used in a concentrated manner are easily registered and many words / phrases that are not frequently used in the word dictionary are registered.

  In addition, since readings and phrases that are stored in the learning area as intermediate words are also deleted from the area, there is an effect of ensuring a storage area for words that are candidates for new word registration. Words that are only temporarily used remain in the learning area without being registered as words, so the learning area is considered to increase.

As described above, it is desired to improve the selection method of candidate candidates for word registration and the selection of candidate word registration subjects to be retained in the learning storage area.
JP-A-3-94367 Fujitsu, “Japanese Word Processor Software OASYS V8 Catalog, page 4,“ Automatically Displaying Long Words by Entering Some Phrases ”,“ Online ”, September 2000, Fujitsu Middleware, [ Search on July 4, 2003], Internet <URL: http://software.fujitsu.com/jp/oasys/CATALOGV8/oasys_v8.pdf>

  The problem to be solved is to improve the method of selecting and organizing registration candidate candidates to stay in the learning storage area and the method of automatically selecting and registering candidate candidates to stay in the learning storage area, It is to provide a means for efficiently performing automatic word registration.

  The present invention includes a word dictionary, a user dictionary in which a user registers corresponding readings and phrases, and a temporary dictionary that stores corresponding readings and phrases as candidates for registration in the user dictionary, In the kana-kanji conversion system that preferentially refers to the temporary dictionary over the user dictionary when converting the reading into words, the registration candidate storage means 1 registers the reading, the word, and the current time as registration candidates in the user dictionary as registration candidates. Is stored in the temporary dictionary in association with the time set as.

  When the conversion confirmation time storage means 2 determines kana-kanji conversion based on the readings and phrases stored in the temporary dictionary by the registration candidate storage means 1, the conversion confirmation time corresponding to the readings and phrases stored in the temporary dictionary Remember.

  When the conversion is confirmed, the conversion confirmation number counting means 3 counts the number of conversion confirmations corresponding to the readings and phrases stored in the temporary dictionary and stores them as the number of conversion confirmations.

  The elapsed time calculation means 4 calculates the elapsed time from the candidate set time stored in the registration candidate storage means 1 to the current time corresponding to the reading and the phrase and stores it as the temporary dictionary storage elapsed time.

  The user dictionary registration means 5 calculates a predetermined number of times that the temporary dictionary storage elapsed time stored when the conversion is confirmed exceeds a predetermined number of hours stored in advance and the stored number of conversion determinations is stored in advance. If it exceeds, the reading of the registration candidate and the phrase stored in the temporary dictionary are registered in the user dictionary.

  In the kana-kanji conversion system, when the deletion candidate extracting means 6 converts and confirms the input reading based on the temporary dictionary into a phrase, the conversion confirmed reading including the same reading as the reading and the reading other than the phrase Extract words and store temporarily.

  The inactive time calculating means 7 calculates the time from the conversion confirmation time stored in the temporary dictionary to the current time corresponding to the reading and words temporarily stored by the deletion candidate extracting means 6 and temporarily stores it as the inactive time. To do.

  The temporary dictionary storage deleting means 8 has a temporarily stored inactive time that exceeds a predetermined time set in advance, and the conversion confirmed number stored in the temporary dictionary corresponding to the reading and the phrase is not more than the predetermined number. It deletes readings and phrases and related information stored in the temporary dictionary at a certain time.

  As described above, the first feature of the present invention is that the word registration in the user dictionary is temporarily stored in the temporary dictionary with the reading of the word as a registration candidate and the phrase, and the kana-kanji conversion has priority over the user dictionary. Search the temporary dictionary first, present conversion word candidates, and when the user selects and confirms, counts and stores the usage results, and counts as the elapsed time from the time of registration in the temporary dictionary as a candidate In other words, registration in the user dictionary is determined on the basis of the actual usage record.

  The second feature is that the readings and words of registration candidates in the user dictionary are automatically collected in the process of Kana-Kanji conversion, or the readings and characters required by the user as shown in the prior art. Since the correspondence with the column is automatically collected from the process of the user's character string operation, the user is positively stored in the temporary dictionary as a candidate except for those registered in the user dictionary. The number of readings and phrases will continue to increase, but the number of confirmed conversions in the Kana-Kanji conversion of users will be counted and automatically deleted and organized by monitoring the period after they are no longer used. It is that you are.

  That is, the present invention is most important to realize that the readings and phrases that are candidates for registration in the user dictionary are automatically deleted from candidates or registered in the user dictionary based on the usage record of kana-kanji conversion. Features.

  The user dictionary registration means of the present invention appropriately determines the necessity of a combination of a reading and a phrase that the user thinks to require kana-kanji conversion based on the user's kana-kanji conversion results and stores it in the user dictionary. Appropriate combinations of unnecessary readings and phrases that do not need to be registered or stored as candidates are automatically determined and automatically deleted from the candidates. There is an advantage that an easy user word dictionary can be constructed. In addition, the automatic reading of registered candidates and the phrase deletion function in the process of automatically building a user dictionary can suppress an increase in necessary resources, so that it can be applied to a small-scale apparatus. There is an advantage. This automatic registration candidate reading and word deletion function can reduce unnecessary presentation of kanji conversion candidates, thereby improving the user's operation comfort.

  In the Kana-Kanji conversion of the character input part from the keyboard of the personal computer, the conversion candidate by the correction operation of the user's Kana-Kanji conversion as shown in the prior art and the conversion candidate by the combination of the reading and the phrase shown by the user's conversion operation Apply to a system that registers in the temporary dictionary, searches for readings and phrases stored in the temporary dictionary corresponding to the input character string, and presents them as conversion candidates on the screen. An appropriate automatic word registration system was realized.

  FIG. 2 is a configuration diagram of an embodiment of the present invention. In this embodiment, a user inputs a kana character string from the input / output device 11 to create a kana-kanji mixed sentence, and the operation on the screen in the mechanism of the kana-kanji conversion device and the automatic registration in the dictionary. Demonstrate the function of deletion from the dictionary.

  The kana-kanji conversion control unit 12 uses the dictionary search unit 13 to convert the character string input from the input / output device 11 operated by the user with reference to the word dictionary 14, the user dictionary 15, and the temporary dictionary 16. This searches for sentence conversion candidates.

  This conversion candidate is displayed on the input / output device 11 by the conversion candidate display means 17, and when the user instructs to select on the screen, the conversion candidate selection means 18 recognizes the conversion confirmation and notifies the conversion confirmation determination means 20.

  In the course of the conversion confirmation, the conversion confirmation determination means 20 sets the unknown word correction temporary dictionary registration means 19 when the user edits, corrects and confirms on the screen by the conversion candidate display means 17 and the conversion candidate selection means 18. The calling / unknown word correction temporary dictionary registration means 19 automatically registers the first input unknown word reading in the temporary dictionary 16 in combination with the edited and corrected word / phrase.

  When the conversion is confirmed by any of the presented conversion candidates, the temporary dictionary registering means 21 associates the “reading” input at the time of conversion confirmation with the “word” that has been confirmed for conversion in association with the temporary dictionary. 16 is registered.

  When the kana character string is input, the temporary dictionary 16 registered in this way is referred to first in the dictionary search by the kana dictionary search means 13, and the conversion candidate display means 17 displays a list of conversion candidates. become.

  As described above, the conversion confirmation determining unit 20 determines the contents to be registered in the temporary dictionary 16 at the time of conversion confirmation, and then passes control to the temporary dictionary statistics management unit 22.

  The temporary dictionary statistics management means 22 statistically processes and manages history information used for confirming the conversion of a set of readings and phrases that are registered in the temporary dictionary 16 and stays there. Based on these statistical information and preset reference values, pairs of readings and phrases staying in the temporary dictionary 16 are registered in the user dictionary by the user dictionary registration means 24 or deleted by the temporary dictionary deletion means 23. Thus, the registration enhancement in the user dictionary 15 and the arrangement of the contents of the temporary dictionary 16 are automatically realized.

  FIG. 3 is a diagram for explaining the configuration of the temporary dictionary. This figure shows the portion of the temporary dictionary 16 in a tabular form, and each row shows a dictionary element to which statistical management information related to the corresponding reading and phrase is added.

  As indicated by the name in the first line of the table, each element is a number given for explanation, and the reading indicates the reading of kana-kanji conversion. The word represents a word to be converted corresponding to reading, the set date represents the date newly stored in the temporary dictionary 16, and the latest confirmed date is the date when kana-kanji conversion is confirmed by the combination of this reading and the word at the time of kana-kanji conversion. Is written. The number of times of determination is counted in this column when conversion is confirmed.

  The content of FIG. 3 will be described by way of example. The element of the temporary dictionary 16 indicated by the number 1 is aa (where the lower case letters of the alphabet indicate kana characters, and similarly the upper case letters of the alphabet are used as characters indicating phrases. The date when the set date is 20030701 and stored for the first time on July 1, 2003 in the statistical management information added to the phrase AA corresponding to Is July 1 and the number of conversion confirmations is 2 times.

  Also, the word AAA is set on April 1 corresponding to the same reading aa, the latest confirmed date is August 1, and the number 2 indicates that the conversion has been confirmed with the combination of this reading and the phrase 9 times so far. It can be understood by the elements of the temporary dictionary shown.

  FIG. 4 shows an explanatory diagram of an example conversion candidate display screen. When performing input that involves Kana-Kanji conversion, the user performs conversion processing by checking and selecting the character string to be converted displayed on the screen, the converted word, and the list of conversion candidate words during conversion. To enter characters. In the figure, an example of a conversion candidate list of combinations of readings and phrases displayed on the screen is shown, and the contents of statistical management information that is not displayed on the screen but is stored in the temporary dictionary are shown in comparison.

  For example, assuming that the current date is August 1, there are two conversion candidate words AA and AAA corresponding to the reading aa as shown by the numbers 1 and 2 in FIG. As a display example, AAA and AA are displayed side by side.

  Although not displayed on the screen, the number of determinations, the period from the setting, and the period from the previous determination are calculated and displayed from the statistical management information corresponding to each set of readings and phrases. An asterisk (*) added after the number of confirmed times indicates a combination of a reading and a phrase that has been confirmed to be converted this time. In addition, the registration and deletion indicated by the arrow and the framed characters shown in the processing column are that the contents stored in the temporary dictionary as a result of the final conversion confirmation are registered in the user dictionary, and are deleted from the temporary dictionary. Indicates that

  Here, the reading aa is confirmed to be converted to the word AAA at this time, but the period since the provisional dictionary is set is 4 months, and the number of determinations is 9 times, which is used in accordance with preset criteria. It is shown that it was registered in the person dictionary.

  Here, with reference to the explanatory diagram of registration in the user dictionary shown in FIG. 5, a criterion for registering the word AAA for the reading aa in FIG. 4 in the user dictionary will be described. As shown in the figure, the setting date for the temporary dictionary is shown at the left end of the time axis extending horizontally, the latest fixed date is shown at the right end, and this is the current date. As shown below the time axis, if the period from the set date to the current date is N days, and the number of conversions determined in the meantime is n times, as shown in the lower part of the figure, N is the registration criterion. It is checked whether it is a period (for example, 3 months) or more, and if so, it is checked whether n is the registration reference number (for example, 3 times) or more. As a result, when both are above the standard, they are registered in the user dictionary.

  This is simply the case when the number of conversion confirmations is counted more than the standard, and when reading and phrase pairs are temporarily concentrated to create a specific document, or when it is necessary for a specific task If the words corresponding to readings such as the names of people who belonged for a specific period are special, use it as it is practically acceptable if Kana-Kanji conversion is processed in the state stored in the temporary dictionary. Is not registered in the user dictionary.

  Conversely, when conversion is confirmed over a reference period, if the number of conversion confirmations is small, it is not registered in the user dictionary. As an example, the reading aabb and the word AABB in FIG. 4 are shown as having been confirmed to be converted this time, but the period from the setting is 4 months or more, but the number of times of confirmation is 2 times or less than the reference number. Therefore, this time, it is indicated that the statistical management information is not updated but registered in the user dictionary.

  Next, an example of deletion from the temporary dictionary will be described. When the reading in the screen example shown in the lower part of FIG. 4 indicates that the word candidate is indicated as BBB, B, BBBB, BB with respect to bb, when the conversion is confirmed by selecting BBB, the word BB is It is an example that has been deleted.

  FIG. 6 shows an explanatory diagram of deletion from the temporary dictionary, which will be described first. That is, the deletion is shown in the lower part of FIG. 6 when the elapsed period from the latest conversion confirmation date to the present is M days, and the number of conversion confirmations from the date set in the temporary dictionary to the latest confirmation date is m times. Thus, first, it is determined whether M is the deletion reference period (for example, 3 months) or more, and if it is longer than the reference, it is determined whether m is the deletion reference number of times (for example, 2 times) or less.

  Here, when it is determined as Yes, information related to the combination of the reading and the phrase is deleted from the temporary dictionary.

  This will be described with reference to an example of reading bb in FIG. For the combination of reading bb and phrase BBB, the fixed number of times is two, four months after being stored in the temporary dictionary, and the standard for registering in the user dictionary is not satisfied and the statistical management information is only updated. However, at this time, unlike the example in which the above-mentioned reading is aabb, there are other conversion candidates for the same reading, so deletion from the temporary dictionary is determined based on statistical management information corresponding to other words become.

  For word B, the number of times of confirmation is one and meets the deletion criteria, but the period from the last time of confirmation is one month, which does not meet the criteria. For word BBBBB, the time from the last time of confirmation is four months, which is equal to or more than the standard Is 4 times and does not satisfy the standard, these are only updated statistical management information and are not deleted. For the word BB, the deletion process is executed from the temporary dictionary because the number of determinations is 1 and the period from the previous determination is 4 months, which satisfies the deletion criteria.

  In this way, the readings and phrases stored in the temporary dictionary are first referred to in the Kana-Kanji conversion process, and are retained in order to determine whether they should be semi-fixedly registered in the user dictionary. It has a function to determine registration in the user dictionary, and determines whether it should be a candidate for registration, and deletes those that are less likely to always enable the temporary dictionary function. I try to keep things organized so that I can do it. In addition, this is effective in order to enable the resources occupied by the temporary dictionary and to enable application to a small-scale device in particular.

  The operation will be described step by step with the flowchart of the process of performing the reading and registration of words and phrases in the user dictionary and deletion from the temporary dictionary and deletion from the temporary dictionary at the time of conversion confirmation as candidates for registration in the user dictionary staying in the temporary dictionary as described above. .

  FIG. 7 is a flowchart for explaining the operation of registration in the user dictionary when the conversion is confirmed. This flowchart shows the processing executed when the conversion of kana-kanji conversion is confirmed. It is determined whether or not the combination of the reading and the phrase confirmed in FIG. 7 should be registered in the user dictionary. The deletion process from the dictionary is performed.

  In step S71, a temporary dictionary is searched with a set of readings and phrases.

  If it is not registered in the temporary dictionary in step S72, the process proceeds to step S74 to newly register in the temporary dictionary.

  In step S73, the latest fixed date, which is statistical management information, is stored at the time of conversion determination, and the number of determinations is counted. In step S75, an elapsed period from the time point set and stored in the temporary dictionary to the present time is calculated.

  In step S76, it is determined whether the calculated lower period is equal to or greater than a reference value for registration determination. In step S77, it is determined whether the counted number of conversion confirmations is equal to or greater than a reference value.

  When it is determined that both of them satisfy the criteria, they are registered in the user dictionary in step S78.

  In both cases where any of the criteria is not satisfied and when the information is newly registered in the temporary dictionary as described above, the process proceeds to the deletion determination process from the temporary dictionary shown in FIG.

  FIG. 8 is an explanatory diagram of an operation flowchart for deleting from the temporary dictionary. This is executed after the registration determination process shown in FIG.

  In step S81, words having the same reading as the conversion-confirmed reading are extracted from the temporary dictionary. Although not shown in the figure, if there is no target word here, the process is immediately terminated (to END).

  In step S82, statistical information is sequentially extracted from the extracted reading and phrase pairs. As described above, when there is a combination of different words / phrases for the same reading when conversion is confirmed, the conversion candidates that are less likely to be converted are arranged. Conversion confirmation may be tried and converted at the user's operation stage, and as described above, there may be a temporary use of words / phrases. The timing for determining the possibility of other candidate phrases is set.

  In step S83, it is confirmed whether all the combinations of the extracted readings and phrases have been judged.

  In step S84 and step S85, for the extracted word or phrase, it is determined whether the active period is equal to or greater than the reference value, and the number of determinations is equal to or less than the reference value. Is deleted from the temporary dictionary.

  In both cases where any of the criteria is not satisfied and when the deletion is performed, the process proceeds to step S82, and the processing is performed for all the combinations of the extracted readings and phrases.

  As described above with reference to the flowchart, registration processing in the user dictionary and useless registration by the determination process associated with the confirmation process of kana-kanji conversion for combinations of readings and phrases that are candidates for registration in the user dictionary retained in the temporary dictionary It was found that the temporary dictionary can function effectively by deleting the candidates.

  A Kana-Kanji conversion device that inputs a Kana character string in some way and converts it into a kanji-mixed sentence, and has a function to register it in the user dictionary, or supports a Kana-Kanji conversion confirmation history Thus, the present invention can be applied to an input support apparatus that displays as conversion candidates. The device may be an individual device or a device shared by a plurality of people, and can also be applied to key input of a small mobile phone from an input system such as a computer, a personal computer, or a word processor.
