Summary of the invention

Problems to be Solved by the Invention

However, even with the same type of form, the corresponding item names (item names) may differ depending on the local government or company. Therefore, when trying to standardize item names for many types of forms, there was a problem that the list of item names would be huge and it would be extremely labor intensive to organize them manually. Therefore, it is desirable to set a standard item name for the item name that is used as the same meaning in multiple forms, but to further improve the standardization accuracy of the item name, it is included in the item name. The words are synonymous with each other \¥02020/175662 2 卩 (: 171?2020/008190

It is desirable to be able to determine whether or not it is a synonym.

[0006] The present invention has been made in view of the above problems, and an object thereof is whether words in a plurality of item names used in a plurality of forms are synonyms or synonyms. Another object of the present invention is to provide a synonym dictionary for determining whether or not a dictionary, a dictionary creation device for creating a synonym dictionary, a dictionary creation method, and a dictionary creation program. Means for solving the problem

According to the dictionary creating device of the present invention, the above problem is a dictionary creating device for creating at least one of a synonym dictionary and a synonym dictionary of item names of a form, which is described in a plurality of forms. And an item name acquisition unit that acquires a plurality of item names, and one or more words included in each of the plurality of item names acquired by the item name acquisition unit are classified based on a predetermined condition. For each common word group, it is determined whether the words in the common word group are synonymous or synonymous with each other based on the first processing unit that creates the common word group and the information that identifies the form. And a second processing unit that does.

With the above configuration, it is possible to determine whether the words in the multiple item names used in multiple forms are synonyms or synonyms, and based on the determination results, the synonym dictionary, A synonym dictionary can be created.

[0008] In the above dictionary creation device, the first processing unit may classify words other than the common word of item names including words common to a plurality of the item names into the same common word group. ..

In the above dictionary creating device, the second processing unit determines that the words are synonymous when the words in one common word group are not used in the same form. Good to do.

In general, the same item name rarely appears multiple times in the same form, so words other than common words, that is, words used in pairs with common words, are used in the same form. If not, it can be determined as a synonym. By doing this, a word other than the common words in the common word group, that is, a synonym dictionary can be created. \\02020/175662 3 卩(: 171?2020/008190

By learning these series of processes as a learning model for machine learning, a more automated and efficient dictionary generation function can be constructed.

[0010] In the above dictionary creation device, the item name acquisition unit acquires, for each item name, form identification information that identifies a form in which the acquired item name is described, and the common word group is common. The word group storage unit has a word belonging to the common word group and form identification information of a form in which the word is described for each word, and the second processing unit is a processing target. When words do not have common form identification information, it is preferable to distinguish the words from each other as synonyms.

By doing this, it is possible to create a synonym dictionary of words used in pairs with common words classified into common word groups.

[001 1] In the dictionary creation device, the second processing unit determines the words to be synonyms when the words to be processed have common form identification information.

By doing this, it is possible to create a synonym dictionary for a single word that is used as a pair when classified into a common word group.

According to the dictionary creating method of the present invention, the above problem is a dictionary creating method by a dictionary creating apparatus for creating at least one of a synonym dictionary and a synonym dictionary, wherein the dictionary creating apparatus comprises: An item name acquisition step of acquiring a plurality of item names described in a plurality of forms, and one or a plurality of words included in each of the plurality of item names acquired in the item name acquisition step based on a predetermined condition. Based on the first processing step of classifying and creating one or more common word groups, it is determined whether the words in the common word group are synonymous or synonymous with each other based on the information identifying the form. The second processing step of discriminating for each word group is provided to solve the above problem.

By doing this, it is possible to determine whether the words in the multiple item names used in multiple forms are synonyms or synonyms, and the synonym dictionary is based on the determination results. , You can create a synonym dictionary. \¥02020/175662 4 卩 (: 171?2020/008190

[0013] According to the dictionary creation program of the present invention, the above-mentioned problem is a dictionary creation program for creating at least one of a synonym dictionary and a synonym dictionary of item names of a form. An item name acquisition unit that acquires a plurality of listed item names and one or more words contained in each of the plurality of item names acquired by the item name acquisition unit are classified based on predetermined conditions. However, the first processing unit that creates one or more common word groups and whether the words in the common word groups are synonymous or synonymous with each other is determined based on the information that identifies the form. It is solved by making it function as the second processing unit that determines for each group.

By doing this, it is possible to determine whether the words in the multiple item names used in multiple forms are synonyms or synonyms, and the synonym dictionary is based on the determination results. , You can create a synonym dictionary.

For example, a “form” is used to apply for a local government such as a municipality, a country, or a private company. Specifically, birth notification, pregnancy notification, etc. correspond to an example of a “form”.

The “item name” is a component of the form and is information for defining the content and format of the input information to the form. For example, "child's name", "child's date of birth", etc. correspond to an example of the above "item name".

“Synonyms” are synonyms when two or more different words have the same meaning as each other, especially when they are used as words showing the same attribute in a form item.

“Synonyms” are synonyms when two or more different words have different meanings, especially when they are used as words that indicate different attributes in a form item.

A “synonym dictionary” is a collection of data that has information that allows determining that two or more words are synonyms for each other. For example, if “child” and “child” are synonymous with “name” and “name”, it is possible to determine that these words have a synonymous relationship by referring to the synonym dictionary. ..

A "synonym dictionary" is a collection of data that has information that enables two or more words to be synonymous with each other. For example, if “child” and “mother” are synonyms, and “name” and “date of birth” are synonyms, it is possible to determine that these terms are synonymous by referring to the synonym dictionary. Is.

In the following, “synonyms” and “synonyms” are collectively referred to as “synonyms”, and “synonyms dictionary” and “synonyms dictionary” are also referred to as “synonyms”. "Synonym dictionary" is a data collection of the above "synonym dictionary". \¥02020/175662 6 卩 (: 171?2020/008190

It means both a union and a separate set of data in a "synonym dictionary", or a set that has information that allows a synonymous relationship and a heteronymous relationship to be determined in one data set. However, both shall be included.

[0018] [Configuration of information processing system 1]

As shown in FIG. 1, the information processing system 1 includes a synonym dictionary creating device 10 (hereinafter referred to as “dictionary creating device 10 ”) and a form processing device 30. The dictionary creating device 10 and the form processing device 30 are communicably connected via a network such as an internet or an intranet (not shown).

The form processing device 30 is connected to the scanner 40.

The scanner 40 is a device that captures image information by optically scanning a paper medium. In the present embodiment, the scanner 40 outputs a scan image (image information) obtained by scanning the form to the form processing device 30.

Report? Are standard documents such as books, slips, and application forms. In the present embodiment, it is assumed that various types of forms are captured by the scanner 40 and output to the form processing device 30. In addition, multiple forms to be processed when setting the standard item name should be the same procedures. Specifically, for example, the forms used for various local governments for the procedure of birth registration are processed.

The form processing device 30 is a computer that processes the form captured by the scanner 40. Specifically, the form processing device 30 executes XX 8 (optical character recognition) on the form to obtain the character string described in the form. In addition, the form processing device 30 determines whether or not the form? The table structure of is analyzed. More specifically, the form processing apparatus 30 divides the form into item columns, input columns, and fill-in input columns, and analyzes information on item names described in the item column (and fill-in input column). ..

The item column is an area in which a character string as an item name is written, and the input column is an area in which no character string is written and the information corresponding to the item column is input. And in the blank entry field, a character string is described, and information is entered between the character strings. This is the area to

An input device 3 1 is connected to the form processing device 30 and information can be input via the input device 3 1. In addition, a display device 32 is connected to the form processing device 30, and a U screen or the like can be displayed on the display device 32.

[Outline of Processing Executed by Dictionary Creation Device 10]

Here, an outline of the processing executed by the dictionary creating device 10 will be described with reference to FIG.

[0028] As shown in Fig. 2, the dictionary creation device 10 is configured to manage a plurality of procedures related to various procedures. \¥02020/175662 8 卩 (: 171?2020/008190

Acquire form group 〇 consisting of forms. Multiple document contains a form on the same ^_ procedure that is needed use in more than one municipality. Even in the same ^_ procedure, when the municipality is different, because the item name, which is the form and use of the form is different, contains each of the book form to the form group ◦. Here, each form includes one or more item names such as “8”, “Mimi”, and “0”. Item name 丨 is a phrase that contains one or more words. Furthermore, each item name includes a form account that can identify the form.

[0029] Then, the dictionary creating device 10 extracts the item name item from each form. In this case, the procedure identification information, the form identification information, which is the identification information of the procedure mouth, the form I mouth, etc., can be identified so that the item name extracted from which form belonging to which procedure can be identified. Is acquired together with the item name. Here, the entire item name 丨 extracted from the forms included in the form group 〇 is referred to as an item name group 丨.

Next, the dictionary creating device 10 classifies the item name I included in the item name group ◦ into a common word group (first process: common word group creating process).

In the first process, the dictionary creation device 10 acquires one procedure (procedure) to be processed, and in the item name I included in the item name group ◦, the item name I belonging to the procedure is included in the item name. Group item names with common words (nouns) into common groups.

Specifically, the dictionary creating device 10 extracts a noun from the words (morphemes) obtained by decomposing the item names 丨1 and 丨2 by morphological analysis. In the following, nouns extracted by morphological analysis are called "words".

Then, when the two item names 丨1 and 丨2 contain a common word, that is, the same word, a group (common word group) that collects words used in pairs with the common word is created. To do.

[0032] For example, when the item name 丨1 is "child's name" and the item name 丨2 is "mother's name", the common words are "name". ”Is created, and as a member of the group, the word (noun), which is a word (noun) paired with “name” in item name 丨 1 and item name 伨 2, \¥02020/175662 9 卩 (: 171?2020/008190

,” and “mother” are classified into “name” groups. Also, the common word group includes a form entry corresponding to each word.

The dictionary creating device 10 carries out the first process for all item names I belonging to the procedure to be processed, and creates a common word group for the item names of procedure 8. Then, this process is repeated for each procedure to create a common word group for all procedures.

The procedure 8 to be processed can be input by the user and acquired from the input. Alternatively, the dictionary creation device 10 may extract and process only the procedure to be processed from the procedure I or the like of the item name group.

In the above process, a common word group is created for each procedure, but if you want to create a common word group across procedures, process all item names included in the item name group ◦. You can also do it.

[0034] Next, the dictionary creation device 10 determines whether the words in the group are likely to be synonyms or synonyms for each of the common word groups created in the first process. Is determined to be high, and synonym candidates and synonym candidates are created (second process; synonym candidate creation process).

[0035] Specifically, the dictionary creating apparatus 10 determines whether or not words to be processed are used in the same form using a form entry. When the words are used in the same form, the dictionary creation device 10 determines that there is a high possibility that they are “synonyms”, and the synonym candidates are candidates for synonyms. Update the memory. On the other hand, when words are not used in the same form, it is determined that they are likely to be “synonyms”, and the synonym candidate storage unit is updated as a synonym candidate.

[0036] For example, when the words "children; form 1" and "children; form 2" are classified as words and their form mouths classified in the "name" group, the form mouths are Since they are different, it is determined that they are not used in the same form, and thus “child” and “child” are updated as “synonyms” candidates.

[0037] The above second process is executed for all groups, and for all procedures. \¥02020/175662 10 ((171?2020/008190

By executing the above, synonym candidates and synonym candidates are created.

[0038] The dictionary creation device 10 presents the synonym dictionary candidates created in the second process to the user and accepts the approval input. Specifically, the dictionary creating device 10 causes the display unit provided in the dictionary creating device 10 or a display device or the like connected via a communication line to display the information of the synonym dictionary candidates. Then, it receives an input from an input device connected directly or via a communication line.

[0039] The dictionary creation device 10 accepts approval input from the user, reflects approval/rejection information for each candidate from the synonym candidate, and creates a final synonym dictionary. , Update (Synonym dictionary update process).

[0040] In the above embodiment, the synonym candidate is created, and the approval/disapproval of the candidate is accepted to determine the final synonym dictionary. However, the present invention is not limited to this. The synonym candidates created may be fixed as the synonym dictionary as they are.

[0041] In this way, the dictionary creation device 10 determines whether the item name 丨 acquired from a plurality of forms belonging to a procedure is a synonym or a synonym, and creates a synonym dictionary. create. It should be noted that the same-objection language dictionary that is created is one that can take advantage of the different item names of different form in which a plurality of local governments Te same ^_ procedure smell is using common, at the time of standardization.

Further, the series of processes can be learned as a machine learning learning model. By learning in this way, it becomes possible to build a more automated and efficient dictionary generation function.

[0064] As shown in Fig. 4, the dictionary creation device 10 initializes 3 indicating the number of procedures to 1 (3 1), and selects ^_ Select procedure 8 (32). The selection of the procedure may be executed by receiving the input from the user.

[0065] Then, the dictionary creation device 10 initializes the variable 丨 to 1 (3 3) and acquires the item name I belonging to the selected procedure 3 (3 4) and morphologically analyzes the item. Extract the nouns included in the name,

To get (3 5). Next, the dictionary creating device 10 selects the item name I _{+ 111} belonging to the procedure 3 (36), and similarly \¥02020/175662 16 卩(: 171?2020/008190

Elementary analysis is performed to extract the nouns included in the item name 丨_{| + 111} , and the words 乂₁ to 乂[ ₃ are acquired (

3 7) ₀

[0066] Next, the dictionary creation device 10 extracts the extracted words! ~ And the word ₁ ~ [[ ₃ are compared to determine whether there is a common word (38). When there is no common word (3 8; N 0), the process ends. On the other hand, when there is a common word (3 8; 丫 6 3), it searches the common word group storage section 20 (3 9) whether the common word group 〇 _¥ of the common word has already been created.

[0067] The dictionary creation device 10

In the common word group 〇 _¥ , the words 】～ and the words ₁ to 侂 [ ₃ , and the forms of each word are stored in the common word group (3 10). On the other hand, when the common word group 〇 _¥ does not exist (39; N 0), the dictionary creation device 10 creates a new common word group 〇 _¥ and adds the word! ~ And word ₁ ~ [ ₃ , and the form of each word is stored in the common word group 〇 _¥ (3 1 1).

[0068] The dictionary creating device 10 determines whether or not the item name 丨_| +111 is the last item name (3 1 2 ), and all the item names 丨

If the process for is not completed (3 1 2 ;○), add 1 to (3 1 3) and proceed to 3 6. If all item names 丨_{| + 111} have been processed (3 1 2 ;丫_{6 3} ), proceed to 3 1 4. If the processing for all item names I _| is not completed (3 1 4 ;1\100), add 1 to 丨 (3 1 5) and proceed to 3 4. When the processing for all item names 丨_| has been completed (3 1

Go to 4; 丫㊀ 3), 3 1 6.

[0069] The dictionary creation device 10 determines whether or not all the procedures 3 of the plurality of procedures have been processed at 316. If processing for all procedures is not completed, proceed to 317 and add 1 to 3. If the processes for all the procedures have been completed, the process ends.

[0070] Next, the dictionary creating device 10 executes the process shown in FIG. 5 for each of the common word groups created as described above. First, the dictionary creating device 10 initializes the variable 3 and the variable !< (3 2 1) and acquires the procedure 3 (3 2 2). Next, the dictionary creation device 10 selects the common word group ◯ _! <(3 2 3). Then I \¥02020/175662 17 卩(: 171?2020/008190

_Is initialized (3 2 4) and a direct product of the words stored in the common word group 〇 _! ^ is created from the common word group 〇 _! ^ (3 2 5). Then, for each element of the direct product, a count number indicating the number used in the same form is calculated (3 2 6)

.. This is calculated by increasing the form I 0 of each word in the common word group ◯ _! ^ for each form I 0.

[0071] dictionary creating apparatus 1 0, the calculated number of counts is determined whether 0 (zero) or greater than (3 2 7), when greater than 0 {2 1;丫_{6 3),} their single It is determined that the word is a synonym, and it is written as a synonym in the same-synonym candidate storage unit (3 2 8), and the process proceeds to 3 30. On the other hand, when the count number is 0 (3 2 7 ;1\100)

, These words are determined to be synonyms, and are written as synonyms in the synonym candidate storage section (329), and the process proceeds to 330.

[0072] The dictionary creation device 10 judges whether or not the word I is the last word (3 30), and when the processing for all the words I is not completed, (3 3 0 ;1\1 〇), add 1 to 丨 (3 3 1), and proceed to 3 2 5. When all words have been processed (3 0; ; ₆

, Go to 3 3 2. Next, it is judged whether the processing has been completed for all common word groups ○ _! ^ (3 3 2), and if not completed (3 3 2 ;N 0), 1 is added to 1< (3 3 2). 3), go to 3 2 3. If all item names _I have been processed (3 3 2; 丫_{6 3} ), proceed to 3 3 4.

[0073] In 3 34, it is determined whether or not the process has been executed for all procedures 3 among the plurality of procedures (3 3 4). If processing for all procedures is not completed (3 3 4; N 0), proceed to 3 3 5 and add 1 to 3. When the processing for all the procedures is completed, the processing ends.

In this way, according to the processing shown in FIG. 5, words in the common word group are synonymous with each other based on whether or not the words to be processed in the same form are used in the same form. Determine if it is different. Note that the process shown in FIG. 5 is an example of a process for determining whether or not the same form is used, and the process is not limited to this and may be any process that can determine whether or not the same form is used. \¥02020/175662 18 卩 (: 171?2020/008190

As described above, according to this embodiment, it is possible to acquire a word from the item names extracted from the form and create a synonym dictionary and a synonym dictionary.
