Description

  The present invention relates to a dictionary registration device, a dictionary registration method, and a dictionary registration program for registering words that are not registered in a dictionary.

  In recent years, a kana-kanji conversion system is generally used as a means for inputting Japanese sentences on a personal computer or a mobile phone. Recently, voice recognition systems that can input characters by voice have begun to be used. In these systems, when hiragana input characters are converted into kanji-kana mixed sentences, they are converted into an optimal notation string among word combinations registered in the system dictionary. Therefore, if the word of the notation desired by the user is not registered in the dictionary, it is not correctly converted, and is erroneously converted into an incorrect notation string in which the notation of the word registered in the system dictionary is appropriately arranged. .

  The dictionary registration apparatus is an apparatus that additionally registers words that are not registered in the system dictionary in order to eliminate such inconvenience. However, it is difficult to check in advance which words used by the user are not registered in the system dictionary. Normally, when an erroneous conversion occurs while the user is inputting a sentence, the user knows that the word is not registered in the dictionary for the first time. Therefore, in order to reduce erroneous conversion, every time the user notices the presence of an unregistered word, the word must be additionally registered in the dictionary as needed.

  In order to reduce the trouble of registering words by such a user, a function has been developed that extracts words that are not registered in the system dictionary from a document file created by the user in the past and collectively registers them in the dictionary (for example, Patent Document 1).

JP-A-2-163874

  However, even when the function of batch registration in the dictionary is used, there is a problem that a word that does not exist in the document file is not additionally registered in the dictionary because it may be used in the future, but has not been input so far. For example, if the word “upper lobe of the right lung” was used in a document created in the past, but the word “upper lobe of the left lung” was not used, the word “upper lobe of the right lung” was used from the document. Since only the word is detected, the word “left upper lobe” is not registered in the dictionary. Therefore, when the user inputs “left upper lobe” at a later date, erroneous conversion occurs.

  The present invention has been made in view of the above, and not only the word input by the user or the unknown word detected from the document, but also the related word notation of the input word or the detected unknown word By converting according to the notation conversion rules for converting to notation, and additionally registering the converted notation word in the dictionary at the same time, it eliminates the omission of registration of words that may be input in the future, and the load of user word registration An object of the present invention is to provide a dictionary registration device, a dictionary registration method, and a dictionary registration program that reduce the number of erroneous conversions during document input.

In order to solve the above-described problems and achieve the object, the present invention provides dictionary storage means for storing a dictionary in which words and word attribute information are associated with each other, and input of unknown words that are not registered in the dictionary. An input receiving means for receiving, and searching the dictionary storage means for at least one word having the same attribute information as a part or all of the notation of the unknown word; the unknown word having the same attribute information as the searched word; Notation conversion means for generating at least one conversion word obtained by converting a part or all of the notation into a search word expression; and word registration means for registering the conversion word and the unknown word in the dictionary It is characterized by that.

  The present invention also provides a dictionary registration method and a dictionary registration program that can execute the above-described apparatus.

  According to the present invention, when a word not registered in the dictionary is registered in the dictionary, not only the notation of the word input for registration, but also the notation of the word related to the input word notation is registered at the same time. Can do. For this reason, it is possible to reduce the trouble of registering an unregistered word in the dictionary every time erroneous conversion occurs, and to reduce the occurrence of erroneous conversion.

  Exemplary embodiments of a dictionary registration device, a dictionary registration method, and a dictionary registration program according to the present invention will be explained below in detail with reference to the accompanying drawings.

(First embodiment)
The dictionary registration apparatus according to the first embodiment converts the notation of a new word input by a user into a notation associated with the new word, and registers the converted notation words together in the dictionary.

  FIG. 1 is a block diagram illustrating a configuration of the dictionary registration device 100 according to the first embodiment. As shown in the figure, the dictionary registration apparatus 100 includes an input reception unit 101, a notation conversion unit 102, a word registration unit 103, and a user I / F 110. The dictionary registration apparatus 100 according to the present embodiment stores a notation conversion rule table 120 and a dictionary 121 in a hard disk drive (HDD). The HDD corresponds to notation conversion rule storage means and dictionary storage means in the present invention.

  The input reception unit 101 receives an input of a new word input by a user or an unknown word detected from a document file. Here, the new word means a word that is input by the user by recognizing that it is not registered in the dictionary. An unknown word means a word that is not registered in the dictionary, and a new word is also included in the unknown word.

  The notation conversion unit 102 converts the notation of words accepted by the input receiving unit 101 in accordance with the notation conversion rule table 120. Details of the notation conversion rule table 120 will be described later.

  The word registration unit 103 passes the word converted by the notation conversion unit 102 to the user I / F 110 for display on the conversion notation confirmation screen, and registers the word designated for registration in the conversion notation confirmation screen in the dictionary 121. It is. Details of the conversion notation confirmation screen will be described later.

  The user I / F 110 is a display device such as a display device and an input device such as a keyboard and a mouse. The user I / F 110 displays an input screen, a conversion notation confirmation screen, a registration result confirmation screen, and performs an input operation from these screens. Accept.

  The notation conversion rule table 120 stores conversion rules for word notation, and is referred to by the notation conversion unit 102. FIG. 2 is an explanatory diagram showing an example of the structure of the notation conversion rule table 120. As shown in the example of the figure, the notation conversion rule table 120 stores conversion notation for the notation of a certain word. For example, “lower” is stored as the conversion notation for the notation “upper”. A plurality of conversion notations can be specified. In the example shown in the figure, for the notation “1”, a number from 2 to 9 indicating a one-digit number other than “1” is specified as the conversion notation.

  The dictionary 121 is a dictionary that holds words, and is a dictionary used in a general kana-kanji conversion system, a speech recognition system, or the like. FIG. 3 is an explanatory diagram showing an example of the structure of the dictionary 121. As shown in the figure, the dictionary 121 stores word notations and readings. The dictionary 121 may be configured to store other items such as parts of speech.

  Next, an unknown word registration process performed by the dictionary registration apparatus 100 according to the first embodiment configured as described above will be described. FIG. 4 is a flowchart showing the overall flow of the unknown word registration process in the first embodiment.

  First, the user I / F 110 displays a new word input screen (step S401). FIG. 5 is a schematic diagram showing the contents of the input screen. As shown in the figure, a reading input field 501, a notation input field 502, a part-of-speech input field 503, a registration button 504, and a cancel button 505 are displayed on the input screen. When the registration button 504 is pressed after inputting in each input field, the input word is accepted. When the cancel button 505 is pressed, the unknown word registration process is stopped.

  When the input screen is displayed, the input receiving unit 101 receives an input of a new word by the user (step S402). Next, the notation conversion unit 102 determines whether or not the new word that has received the input includes a portion that matches the “notation” column of the notation conversion rule table 120 (step S403). The collation between the new word notation that accepts the input and the notation of the notation conversion rule table 120 may be performed by the longest matching character string matching in character units, or the new word notation is collated after morphological analysis and divided into morphemes. May be performed. As described above, the matching determination between the partial character string included in the new word notation and the notation of the notation conversion rule table 120 may be configured by any of the general matching methods.

  When the portion that matches the “notation” column of the notation conversion rule table 120 is not included (step S403: NO), the word registration unit 103 registers the accepted new word in the dictionary 121 (step S404). If a matching part is included (step S403: YES), the notation conversion unit 102 acquires the conversion notation corresponding to the notation of the corresponding part from the notation conversion rule table 120, and the corresponding of the new word that accepted the input. The part notation is converted into the acquired conversion notation (step S405).

  When there are a plurality of matching partial character strings, the number of words corresponding to the number of combinations is generated as a converted word. For example, when the input new word is “upper right lobe”, the partial character strings “right” and “up” match the notation in the notation conversion rule table 120. Accordingly, the three words “lower right lobe”, “upper left lobe”, and “lower left lobe” are generated as converted words.

  When a plurality of conversion notations corresponding to the notation of the corresponding part are designated, the number of words corresponding to the number of conversion notations is generated as words obtained by converting the notation. For example, when the notation of the corresponding part is the number “1”, the notation conversion rule table 120 designates eight conversion notations from the numbers “2” to “9” as the corresponding conversion notations. Therefore, eight words obtained by converting “1” into respective numbers are generated as words obtained by converting the notation.

  Next, the user I / F 110 displays the converted notation word on the conversion notation confirmation screen (step S406). FIG. 6 is a schematic diagram showing the contents of the conversion notation confirmation screen. As shown in the figure, the conversion notation confirmation screen displays a list of converted word expressions, readings, and parts of speech, and a check box 601 is displayed on the left side of each word. A registration button 602 and a cancel button 603 are displayed at the bottom of the conversion notation confirmation screen.

  By checking the check box 601, it is specified that the converted notation word displayed on the right side is registered in the dictionary 121. When the registration button 602 is pressed, the designated word is registered in the dictionary 121. When the cancel button 603 is pressed, the unknown word registration process is stopped.

  In FIG. 6, whether or not to register can only be specified by a check box 601, but the conversion notation confirmation screen may be configured so that reading and part of speech can be corrected.

  When the registration button 602 is pressed on the conversion notation confirmation screen, the word registration unit 103 checks the check box 601 to determine whether there is a notation designated to be registered in the dictionary 121 (step S407). . When there is no notation designated for registration (step S407: NO), the word registration unit 103 registers only the accepted new word in the dictionary 121 (step S404). If there is a notation designated for registration (step S407: YES), the word registration unit 103 registers the accepted new word and the notation designated for registration in the dictionary 121 (step S408).

  Next, the user I / F 110 displays the word registered in the dictionary 121 on the registration result confirmation screen (step S409). FIG. 7 is a schematic diagram showing the contents of a registration result confirmation screen. As shown in the figure, the registration result confirmation screen displays a list of notations, readings, and parts of speech of words registered in the dictionary 121, and a close button 701 is displayed at the bottom of the screen. When the close button 701 is pressed, the unknown word registration process ends.

  FIG. 8 shows an example of processing for registering a new word input by the user and a word converted from the notation into the dictionary 121 in the dictionary registration device 100 according to the first embodiment, according to the above-described unknown word registration processing. It is explanatory drawing.

  In the example shown in FIG. 8, the case where the user inputs “upper right lobe” as a new word is shown. In this case, the collation with the notation conversion rule table 120 matches the “right” and “upper” partial character strings in the input new word with the notation of the notation conversion rule table 120. , “Below” is acquired from the notation conversion rule table 120. Then, three words are generated by replacing the obtained two conversion expressions one by one or two at the same time, and a total of four words (“upper right lobe”, “lower right lobe”, "Left upper lobe" and "Left lower lobe") are additionally registered in the dictionary 121.

  Note that the dictionary registration device 100 according to the first embodiment is configured such that the converted notation and the registration result are displayed on the screen so that the user can check. You may comprise so that the converted description may be automatically registered as it is, without selecting.

  As described above, in the dictionary registration apparatus 100 according to the first embodiment, not only a new word input by the user but also a notation word obtained by converting the notation of the input new word according to a predetermined notation conversion rule. It is possible to register, and the burden of the user registering a word that is not registered in the dictionary 121 can be reduced. In addition, since a plurality of words can be registered by a single registration process, the occurrence of subsequent erroneous conversion can be reduced.

(Second Embodiment)
The dictionary registration device according to the second embodiment detects an unknown word that is not registered in the dictionary from a document file specified by the user, converts the detected unknown word notation into a related notation, and converts the notation Are also registered in the dictionary.

  That is, the dictionary registration apparatus 900 according to the second embodiment detects an unknown word from a document file designated by the user and accepts the detected unknown word as a word to be input instead of accepting a new word input by the user. However, it is different from the dictionary registration device 100 according to the first embodiment.

  FIG. 9 is a block diagram illustrating a configuration of a dictionary registration apparatus 900 according to the second embodiment. As shown in the figure, the dictionary registration device 900 includes an unknown word detection unit 901, an input reception unit 101, a notation conversion unit 102, a word registration unit 103, and a user I / F 110. Also, the dictionary registration apparatus 900 according to the present embodiment stores the notation conversion rule table 120 and the dictionary 121 in the HDD.

  The second embodiment is different from the first embodiment in that an unknown word detector 901 is added. Other configurations and functions are the same as those in FIG. 1 which is a block diagram showing the configuration of the dictionary registration apparatus 100 according to the first embodiment, and therefore, the same reference numerals are given and description thereof is omitted here.

  The unknown word detection unit 901 detects all unknown words that are not registered in the dictionary 121 from the document file designated by the user, and performs processing to pass the detected unknown words to the input reception unit 101.

  Next, an unknown word registration process performed by the dictionary registration apparatus 900 according to the second embodiment configured as described above will be described. FIG. 10 is a flowchart showing an overall flow of the unknown word registration process in the second embodiment.

  First, the unknown word detection unit 901 detects an unknown word from a document file designated by the user (step S1001). Next, the input reception unit 101 receives an input of an unknown word detected by the unknown word detection unit 901 (step S1002), and the notation conversion unit 102 includes the notation conversion rule table 120 in the unknown word that has received the input. It is determined whether or not a portion matching the “notation” field is included (step S1003).

  If the matching part is not included (step S1003: NO), the unknown word detected by the word registration unit 103 is registered in the dictionary 121 (step S1004). If a matching part is included (step S1003: YES), the notation conversion unit 102 converts the notation of the part into a notation stored in the “conversion notation” column of the notation conversion rule table 120 ( Step S1005).

  Next, the word registration unit 103 registers the detected unknown word and the notation word converted by the above-described process in the dictionary 121 (step S1006). Thereafter, the unknown word detection unit 901 determines whether all unknown words in the document file designated by the user have been processed (step S1007). If all unknown words have not been processed (step S1007). : NO), the process proceeds to the next unknown word detection process (step S1001).

  If all unknown words have been processed (step S1007: YES), the unknown word registration process ends.

  FIG. 11 shows an example of processing for detecting an unknown word from a document file designated by the user and registering it in the dictionary 121 in the dictionary registration apparatus 900 according to the second embodiment in accordance with the above-described unknown word registration processing. It is explanatory drawing.

  In the example shown in FIG. 11, a case where “finding file 001” is designated as an input document file by the user is shown. From the document file, as shown in the figure, the word “upper right lobe” that is not registered in the dictionary 121 is detected as an unknown word. By comparing the detected unknown word with the notation conversion rule table 120, the “right” and “upper” partial character strings in the detected unknown word match the notation of the notation conversion rule table 120. The notations “left” and “lower” are acquired from the notation conversion rule table 120. Then, three words are generated by replacing the obtained two conversion expressions one by one or two at the same time, and a total of four words (“right lung upper lobe”, “right lung lower lobe”) including the detected unknown words are generated. , “Left upper lobe”, “Left lower lobe”) are additionally registered in the dictionary 121.

  Thereafter, although not shown in the figure, the next unknown word is detected from the designated document file, and the notation conversion process and the dictionary registration process are repeated.

  Although the screen is not displayed on the user I / F 110 in the second embodiment, a conversion notation confirmation screen for confirming the converted notation and a registration result confirmation screen for confirming the result registered in the dictionary 121 are displayed. You may comprise.

  As described above, in the dictionary registration apparatus 900 according to the second embodiment, an unknown word is detected from a document file designated by the user, and the detected unknown word is detected according to a predetermined notation conversion rule together with the detected unknown word. Since the notation word converted from the notation can be registered at the same time, the burden of registering the word not registered in the dictionary by the user can be reduced. In addition, since a plurality of words can be registered by a single registration process, the occurrence of subsequent erroneous conversion can be reduced.

(Third embodiment)
The dictionary registration device according to the third embodiment converts the notation of a new word input by the user into a notation associated with the new word, and the converted notation does not satisfy a predetermined registration condition for dictionary registration. Then, the converted notation is divided into constituent elements, and among the divided constituent elements, constituent elements not registered in the dictionary are registered in the dictionary together with new words input by the user.

  FIG. 12 is a block diagram illustrating a configuration of a dictionary registration apparatus 1200 according to the third embodiment. As shown in the figure, the dictionary registration device 1200 includes an input reception unit 101, a notation conversion unit 102, a word registration unit 103, a conversion notation determination unit 1201, a conversion notation division unit 1202, and a user I / F 110. It has. The dictionary registration apparatus 1200 according to the present embodiment stores a notation conversion rule table 120 and a dictionary 121 in the HDD.

  The third embodiment is different from the first embodiment in that a conversion notation determination unit 1201 and a conversion notation division unit 1202 are added. Other configurations and functions are the same as those in FIG. 1 which is a block diagram showing the configuration of the dictionary registration apparatus 100 according to the first embodiment, and therefore, the same reference numerals are given and description thereof is omitted here.

  The conversion notation determination unit 1201 determines whether or not the notation converted by the notation conversion unit 102 satisfies a predetermined registration condition for dictionary registration. The conversion notation division unit 1202 divides the notation determined by the conversion notation determination unit 1201 that the registration condition is not satisfied into components, and performs processing for selecting components not registered in the dictionary 121.

  Next, an unknown word registration process performed by the dictionary registration apparatus 1200 according to the third embodiment configured as described above will be described. FIG. 13 is a flowchart showing an overall flow of unknown word registration processing in the third embodiment.

  The input screen display process, new word input reception process, and notation conversion process from step S1301 to step S1305 are the same as the process from step S401 to step S405 in the dictionary registration device 100 according to the first embodiment, and therefore the description thereof will be given. Is omitted.

  After the notation conversion unit 102 converts the input new word notation, the conversion notation determination unit 1201 determines whether or not the converted notation satisfies the registration condition (step S1306). In this case, the registration condition may be that the number of words or the character string length generated by the conversion of the notation does not exceed a predetermined upper limit value. With this configuration, for example, since the number of words generated by conversion is very large, it is possible to avoid the inconvenience that the number of words that can be additionally registered thereafter is limited when all the words are registered.

  If the registration condition is not satisfied (step S1306: NO), the conversion notation dividing unit 1202 divides the input new word notation into components (step S1307). As a method of division, the new word notation may be divided into a part where the notation is converted and the other part, or the new word notation is divided into morpheme units by performing morphological analysis. You may comprise. Next, the conversion notation division unit 1202 sorts out components that are not registered in the dictionary 121 from the divided components (step S1308). This is because there is no need to further register components already registered in the dictionary 121.

  When the registration condition is satisfied (step S1306: YES), and after unregistered components are selected in the dictionary 121, the user I / F 110 displays a conversion notation confirmation screen (step S1309). The registration designation determination process, the registration process to the dictionary 121, and the registration result confirmation screen display process from step S1310 to step S1312 are the same as those from step S407 to step S409 in the dictionary registration apparatus 100 according to the first embodiment. Therefore, the description thereof is omitted.

  FIG. 14 is a diagram illustrating a dictionary registration apparatus 1200 according to the third embodiment. In accordance with the above-described unknown word registration process, a registration condition for a new word input by a user is determined, and components obtained by dividing the new word are registered in the dictionary 121. It is explanatory drawing which showed the example of the process. In this example, it is assumed that the registration condition specifies that the number of converted notations does not exceed the upper limit 10.

  In the example illustrated in FIG. 14, a case where the user inputs “T2-weighted image” as a new word is illustrated. In this case, since the partial character strings “T” and “2” in the input new word match the notation of the notation conversion rule table 120 by collation with the notation conversion rule table 120, the conversion notation “A” respectively. “S” and “U” to “Z” (25 alphabets), “1” and “3” to “9” (8 numbers) are acquired from the notation conversion rule table 120.

  As a result, when the input new word is added, a total of 26 × 9 = 234 words are generated. Since this does not satisfy the registration condition that the number of converted expressions does not exceed 10, the input new word expressions are divided. In this example, the input new word “T2 weighted image” is divided into three parts “T”, “2”, and “highlighted image” by dividing the new word notation into a part where the notation is converted and a part other than that. Divided into two components. Furthermore, since “T” and “2” are normally registered in the dictionary 121, only “emphasized images” that are not registered in the dictionary 121 are selected and additionally registered in the dictionary 121. Thereby, for example, even when “T1 weighted image” is input thereafter, it can be correctly converted as three word strings of “T”, “1”, and “weighted image”.

  Note that the dictionary registration device 1200 according to the third embodiment is configured such that the converted notation and registration result are displayed on the screen so that the user can check. You may comprise so that the converted description may be automatically registered as it is, without selecting.

  As described above, in the dictionary registration device 1200 according to the third embodiment, an unnecessary conversion notation can be obtained by registering the converted notation in the dictionary only when the converted notation satisfies a predetermined registration condition. Registration can be avoided. Further, when the registration condition is not satisfied, by registering only the unregistered components in the dictionary among the components constituting the input new word, the subsequent erroneous conversion can be avoided.

(Fourth embodiment)
The dictionary registration device according to the fourth exemplary embodiment detects an unknown word that is not registered in the dictionary from a document file specified by the user, converts the detected unknown word notation into a related notation, and converts the notation If the registration condition does not satisfy a predetermined dictionary registration condition, the converted notation is divided into components, and among the divided components, the dictionary together with new words that the user has entered unregistered components in the dictionary To register.

  Next, an unknown word registration process performed by the dictionary registration apparatus 1700 according to the fifth embodiment configured as described above will be described. FIG. 19 is a flowchart showing an overall flow of unknown word registration processing in the fifth embodiment.

  Since the input screen display process and the new word input acceptance process from step S1901 to step S1902 are the same as the process from step S401 to step S402 in the dictionary registration apparatus 100 according to the first embodiment, the description thereof is omitted.

  The notation conversion unit 102 performs a morphological analysis on the new word received by the input receiving unit 101 (step S1903), and searches the dictionary 121 for a morpheme having the same attribute information as the obtained morpheme (step S1904). For example, when the user inputs “upper leaf” as a new word and “upper” and “leaf” are obtained as morphemes, “lower” having the same attribute information as the attribute information “positional relationship” of the notation “upper” Is retrieved from the dictionary 121.

  Next, the notation conversion unit 102 determines whether or not the corresponding morpheme exists as a result of searching the dictionary 121 for the morpheme having the same attribute information as the obtained morpheme (step S1905). If the corresponding morpheme does not exist (step S1905: NO), the word registration unit 103 registers the accepted new word in the dictionary 121 (step S1906).

  If the corresponding morpheme exists (step S1905: YES), the notation conversion unit 102 converts the notation of the corresponding part of the input new word into the notation of the morpheme retrieved from the dictionary 121 (step S1907). In the above example, the notation “lower leaf” obtained by converting the “upper” portion of “upper leaf” to “lower” is generated as a word obtained by converting the notation. When there are a plurality of corresponding morphemes, the number of words corresponding to the number of combinations is generated as words whose notation is converted.

  The conversion notation confirmation screen display processing, registration designation determination processing, dictionary registration processing, and registration result confirmation screen display processing from step S1908 to step S1911 are performed from step S406 to step S409 in the dictionary registration device 100 according to the first embodiment. Since it is the same processing as before, the description thereof is omitted.

  As described above, the dictionary registration apparatus 1700 according to the fifth embodiment can convert the notation by referring to the dictionary storing the attribute information without using the notation conversion rule table.

  In this embodiment, the example in which the notation conversion is performed by referring to the attribute information of the dictionary 121 instead of the notation conversion rule table 120 in the first embodiment has been described. Also in this form, it is possible to convert the notation by referring to the attribute information of the dictionary 121 instead of the notation conversion rule table 120.
