FIG. 6 is a flowchart showing the procedure of the process of specifying the comparison range. The comparison range specifying unit 102b first reads all the thesis data submitted in the past stored in the thesis data storage unit 101c (step S21). Next, the comparison range specifying unit 102b reads all the document data described in the document list stored in the document list storage unit 101b from the document data storage unit 101a and the Internet 130 (step S22). Then, the comparison range specifying unit 102b specifies all the read article data and the acquired document data (such as document data) as a comparison range (Step S23).

Returning to FIG. 2, when the specification of the comparison range is completed, the similarity calculation unit 102c searches the data of the comparison range specified using the description content of the specified determination range as the search key (step S15). The similarity of the description content is calculated (step S16). Specifically, the similarity calculation unit 102c designates a search key to a search program or a search engine using a known search technology, or a search program or a search engine of these to execute a search instruction. Here, as logic for calculating the degree of similarity, for example, a known logic such as syntactic analysis of the description contents of the judgment range of the article data and the description contents of the document data is used. . Then, the document quoting determination unit 102d determines whether the determination range is citing the document of the comparison range by determining whether the calculated similarity is equal to or more than a predetermined threshold (step S17). ).

Then, if the calculated similarity is smaller than the predetermined threshold (step S17, No), it is determined that the determination range does not cite document data or the like in the comparison range, and the process is ended. Here, the predetermined threshold can be arbitrarily determined in accordance with the accuracy required for the quotation determination.

On the other hand, when the calculated similarity is equal to or higher than the predetermined threshold (Yes at step S17), it is determined that the determination range is quoting document data or the like in the comparison range, and then the legality determination unit 102e Determines whether this citation is a legitimate one (step S18). Here, the term "legitimate" is a concept including that the quote is legal under the copyright law, or that the user has requirements set in advance. Specifically, when there is display of the book name near the lower part of the citation place such as the document data in the determination range, the legality determination unit 102e displays the parenthesis "" indicating citation immediately before and after the citation place. If the citation is displayed in a font different from the font of the other parts to indicate that it is a citation, it is determined that the citation is legitimately cited based on the copyright law. In addition to this, when there is a predetermined indication (for example, author's name, author's name, or publisher's name) which affirms the legitimacy of the citation, the citation part is It may be judged that it has been properly cited.

Then, when it is determined that the reference of the determination range is a legal reference (Step S18, Yes), the processing is ended.

On the other hand, when it is determined that the citation of the determination range is not a legal citation (Step S18, No), the reference information acquisition unit 102f refers to the document data etc. (cited document data or cited paper data) Reference information (file name and title of document data etc., URL, folder name etc.), attribute of document data, etc. or attribute of cited article data etc. (step S19). Then, the output control unit 102 h clearly indicates the location at which the document data and the like are cited within the determination range on the citation determination screen and displays the reference information (step S 20).

The processes in steps S15 to S20 are repeatedly executed for all the data in the specified comparison range (step S20a, No). If the processes in steps S15 to S20 have been executed for all the data in the specified comparison range (step S20a, Yes), the process ends.

In the present embodiment, first, the output control unit 102h highlights the portion quoted in the determination range by color change, inversion, or the like. FIG. 7 is a schematic view showing a state in which a cited place is highlighted within the judgment range on the quotation judgment screen. Note that the bold and underlined portions in FIG. 7 are the highlighted portions, that is, the portions of the citation.

Then, when the user designates this cited place via the input device 103, the instruction is accepted by the input control unit 102g, and the output control unit 102h is controlled to display the reference information at the instructed location. There is.

FIG. 8 is a schematic view showing a state in which reference information is displayed on the quotation determination screen. The example of FIG. 8 shows the case where the document data on the Internet 130 is cited, and the URL of the document data is displayed as the reference information. In this embodiment, when the user clicks this URL with the pointing device of the input device 103, the output control unit 102h accesses the WEB page indicated by the URL to display the reference data etc. of the quotation source. Configured. As a result, a professor or the like who makes a citation judgment on article data can easily acquire reference data of the citation source.

Next, the process of identifying the determination target in step S31 will be described in detail. FIG. 12 is a flowchart illustrating the procedure of the process of identifying a determination target according to the second embodiment.

First, the determination range identification unit 102i reads out the created article data and the student register number corresponding to the article data from the article data storage unit 101c (step S41). Next, the determination range specifying unit 102i refers to the history data stored in the history data storage unit 101d, and reads out the presence / absence of the illegal citation and the grade corresponding to the read student registry number (step S42).

Then, the determination range specifying unit 102i determines whether the presence or absence of the unauthorized use read from the history data is “presence” (step S43). Then, if the presence or absence of unauthorized use is "presence" (step S43, Yes), the thesis data created by the student with the student register number, that is, the thesis data read in step S41 is specified as the determination target (step S45).

On the other hand, if it is determined in step S43 that the presence or absence of unauthorized use is "absent" (step S43, No), the determination range specifying unit 102i further determines that the score read from the history data is C or less, that is, C or D. It is determined whether there is any (step S44).

Then, if the grade is C or D (step S44, Yes), the thesis data created by the student with the student register number is specified as the determination target (step S45).

On the other hand, when the grade is higher than C in step S44 (ie, when it is A or B) (step S44, No), the article data read out in step S41 is not determined.

If there are a plurality of created article data to be cited and determined, the processing from step S41 to step S45 is performed on the plurality of article data to specify the article data to be determined.

(effect)
As described above, in the quotation determination support device 900 of the second embodiment, the student register number corresponding to "presence" of the presence or absence of fraudulent citation indicating that there has been a fraudulent citation act in the past from history data, the score is a predetermined value Since the dissertation data created by the student whose student registry number is C or lower is selected as the judgment target from among the plurality of thesis data, the dissertation data of the person who has a high probability of making an illegal citation is judged as the judgment target As a result, the determination accuracy can be further improved, and the determination processing load can be reduced and the determination efficiency can be improved by limiting the determination target only to the thesis data having a high probability of illegal citation.

In the present embodiment, the determination range specifying unit 102i both determines from the history data whether there is an illegal quotation indicating that there has been an illegal quotation act in the past, and determines whether or not the score is a predetermined value or less. However, the paper data to be judged may be specified by only one judgment.

Third Embodiment

Then, the determination range specifying unit 102 j performs morphological analysis on the contents of the read article data according to a known method, and divides the contents into morphemes (step S 52).

Next, the word conversion unit 102k searches the specialized dictionary using the obtained morpheme word as a search key, and for the word registered as the specialized dictionary term, the word corresponds to the specialized dictionary term It is converted into a first candidate term (step S53). In the case of the second and subsequent word conversion, conversion to the nth candidate term (n is an integer of 2 or more) is performed.

Then, it is determined whether the word conversion process is completed for all the words in the article data (step S54), and if not completed (step S54, No), the word conversion process in step S53 is performed. Repeat

On the other hand, when the word conversion process is completed for all the words of the article data (step S54, Yes), the word conversion unit 102k stores the article data of the converted word as corrected article data. It is stored in the unit 101c (step S55).

Then, the word conversion unit 102k determines whether all the candidate terms in the specialized dictionary have been converted (step S56). Then, if conversion into all candidate terms has not been performed (Step S56, No), the word conversion unit 102k selects the next candidate term (the (n + 1) th candidate term) as the term of the specialized dictionary (Step S57) , Steps S53 to S55 are repeated. As a result, for each word of the article data, a plurality of modified version of the article data converted into a plurality of candidate terms are obtained and stored in the article data storage unit 101c.

If it is determined in step S56 that all the candidate terms in the specialized dictionary have been converted (Yes in step S56), the determination range specifying unit 102j specifies a plurality of obtained corrected version paper data as a determination target ( Step S58).

The quoting determination support process is performed on a plurality of corrected version paper data specified as the determination target in this way.

The comparison range specification unit 1021 first extracts two thesis data from all thesis data submitted in the past stored in the thesis data storage unit 101c (step S61). Next, the similarity calculation unit 102m calculates the similarity of the description content of the two extracted article data (step S62). Here, the calculation of the degree of similarity first compares the description of a partial range in one of the two article data with the description content of the other article data, and then the one article data The similarity of each part is calculated while repeating the process of comparing with the description content of the other article data while changing the partial range of the part, and the average value of the similarity of these partial comparison results, etc. Can be calculated as the degree of similarity between all the article data. However, the method of calculating the degree of similarity is not limited to this.

Then, the comparison range specifying unit 102l determines whether or not the calculation process of the similarity is performed for all the past paper data (step S63), and if it is not performed for all the past paper data ( The processes of steps S63 and No) and steps S61 and S62 are repeatedly executed.

On the other hand, when the calculation process of the similarity is completed for all the past article data (Yes at step S63), the document quoting determination unit 102n determines a plurality of documents whose similarity is equal to or more than a predetermined second threshold. If there is a dissertation data, it is determined that there are citations among the plurality of thesis data, and the plurality of thesis data are selected (step S64). Then, the comparison range specifying unit 102l specifies the selected plurality of thesis data as the comparison range (step S65). Therefore, the past paper data quoted to each other becomes the comparison range, and the citation judgment of the paper data to be judged is performed.

(effect)
As described above, the citation determination support apparatus 1600 according to the fourth embodiment performs citation determination on the citation data of the determination target, with the citation data in the past as citation data being used as a comparison range. As the comparison range, it is possible to improve the accuracy of the judgment while preventing the development process and the increase of the manufacturing cost, and limit the judgment object only to the thesis data with a high probability of illegal citation. Thus, the determination processing load can be reduced to improve the determination efficiency.

In the present embodiment, although it is determined that the one having the similarity degree equal to or more than the second threshold is cited among the past paper data, the citation is further determined by the legality determination unit 102e. It may be configured to judge whether or not it is legal, and to specify as a comparison range only when it is illegal.

This form is a form including the correspondence logic when the number of characters to be compared in the article exceeds the number of characters in the search logic. However, the configuration and the process according to the sixth embodiment are the same as the configuration and the process according to the first embodiment except when particularly described, and the same configuration and the process in the first embodiment The description is abbreviate | omitted by using the same name or code | symbol as what was used as needed.

(Constitution)
FIG. 20 is a block diagram showing a functional configuration of the quotation decision support apparatus according to the sixth embodiment. The quote determination support device 2000 differs from the quote determination support device 100 according to the first embodiment in that the control unit 102 includes the similarity calculation unit 102r.

The similarity calculation unit 102r uses the well-known search technology (search engine etc.) and uses the description content of the determination range specified by the determination range specification unit 102a as a search key, and the comparison range specified by the comparison range specification unit 102b. Search from among At this time, if the number of characters of the search key exceeds a predetermined number of restricted characters (for example, 32 characters), an error message is displayed that includes the number of restricted characters and the number of characters of the search key exceeds the number of restricted characters. It is notified from a search engine etc. In such a case, the similarity calculation unit 102r specifies a character within the limited number of characters from the top of the determination range as a search key, performs a search from the comparison range, and stores the search result in a memory or the like. deep. Then, the similarity calculation unit 102 r similarly searches the comparison range using the character string for the next limited number of characters in the determination range as a search key. In this manner, the similarity calculation unit 102 r sequentially designates the search key while moving the character string of the description content of the determination range by the limited number of characters, performs a plurality of searches, and stores the search result Save to The similarity calculation unit 102r calculates the similarity with the determination range, with the search result having the highest appearance frequency among the plurality of search results as the comparison range to be the target of similarity calculation. Note that search results having a predetermined number or more of appearance frequencies may be configured as targets for similarity calculation.

(processing)
Next, citation determination support processing by citation determination support apparatus 2000 of the sixth embodiment configured as described above will be described. The entire process of the quoting determination of the present embodiment is the same as the procedure of the quoting determination support process in the first embodiment described with reference to FIG. In the present embodiment, the procedure of the search process (step S15) performed by the similarity calculation unit in FIG. 2 is different from that of the first embodiment.

FIG. 21 is a flow chart showing the procedure of search processing in similarity calculation in the sixth embodiment. First, the similarity calculation unit 102r searches data in the comparison range as a description content search key of the determination range (step S91). Then, the similarity calculation unit 102r determines whether an error notification that the search key has exceeded the limit number of characters has been received (step S92).

Then, when an error notification that the search key has exceeded the limit number of characters has not been received (step S 92, No), the similarity calculation unit 102 r selects a search result (step S 100), and the search result is The comparison range is the target of similarity calculation, and the similarity to the determination range is calculated as in the first embodiment.

On the other hand, if an error notification that the search key has exceeded the limited number of characters is received in step S92 (Yes in step S92), the similarity calculation unit 102r acquires the limited number of characters from the received error notification. (Step S93).

Then, the similarity calculation unit 102r designates a character string within the limited number of characters as a search key from the head of the determination range (step S94), and searches data in the comparison range with this search key (step S95). The similarity calculation unit 102r stores the search result in the memory (step S96).

Then, the similarity calculation unit 102 r determines whether or not the final character string has been reached as a search key of the determination range (step S 97), and if it has not reached yet (step S 97, No), Among them, a character string for the next limited number of characters is designated as a search key (step S98), and the processes of steps S95 and S96 are repeatedly executed. Although the specific method for specifying the character string for the limited number of characters in this way is arbitrary, as an example, a method for moving the limited number of characters as one unit (for example, in the case of limited number of characters = 32 characters) In the first, the character string from the first character to the 32nd character is used as a search key, and for the second time, the character string from the 33rd character to the 64th character is used as a search key. Method to move in units of one character (for example, in the case of limited number of characters = 32 characters, the first character string from the first character to the 32nd character is the search key, and the second one from the second character to the 33rd character) The following character string is used as a search key, and a search key is specified in the same manner) or a method of moving to any number of characters (for example, in the case of limited number of characters = 32 characters, any number of characters = 1) In the case of characters, the first time the character string from the first character to the 32nd character is the search key, the second time the character string from the 11th character to the 42nd character is the search key, and so on. Method) can be adopted.

On the other hand, when the final character string is reached as the search key of the determination range in step S97 (step S97, Yes), the search result having the highest frequency of appearance is selected from the search results stored in the memory ( Step S99), the selected comparison range is the target of similarity calculation, and the similarity to the determination range is calculated.

(effect)
As described above, in the quotation determination support device 2000 of the sixth embodiment, when the search key exceeds the limited number of characters, the search key is specified by the character string for the limited number of characters in the determination range, and the search key is specified. Since the search is performed a plurality of times while shifting the character string in the determination range, the accuracy of the quotation determination can be improved regardless of the limited number of characters of the search key.

The citation determination support apparatus 100 includes a citation format setting unit 102 s in the control unit 102 and a citation format database (hereinafter, “database” is abbreviated as “DB”) 101 f in the storage unit 101.

The citation format setting unit 102 s is a citation format setting unit that sets a citation format as a reference when judging the legitimacy of citation.

The citation format DB 101 f is a citation format storage unit that associates and stores a type for classifying article data and a predetermined citation format. FIG. 25 is a table showing information stored in the citation format DB 101 f. As shown in FIG. 25, the citation format DB 101 f includes “type”, “citation format”, and “location of legal document storage” as data items, and information corresponding to these is stored in association with each other. The information stored corresponding to the item "type" is information for specifying the type of thesis data, and as exemplified in FIG. 25, the field corresponding to the theme of the article such as "law" or "engineering" Can be stored. The information stored corresponding to the item "citation format" is information for specifying a legal citation format, and as illustrated in FIG. 25, it is necessary to store "" "," "", etc. Can. The information stored corresponding to the item "legal document storage location" is information for specifying the storage location of the document regarded as legal, for example, as shown in FIG. 25, "Z: \ quotaion \ law \ “Z: ¥ quotaion ¥ eng ¥” and the like can be stored as a folder name etc. where the document is stored. In addition, as the "document to be regarded as legal", for example, a document to be regarded as legal when the document is cited corresponds. The storage method and storage timing of the information stored in the citation format DB 101 f can be arbitrarily stored in the citation format DB 101 f, for example, in advance via the input device 103, or stored in the citation format DB 101 f in the citation format setting process described later. can do.

(Processing-quote judgment support process)
Next, the citation determination support process executed by citation determination support apparatus 100 of the seventh embodiment configured as described above will be described. FIG. 26 is a flowchart showing the procedure of the quotation determination support process of the seventh embodiment. The processes of steps SA1 to SA13 except steps SA2 and SA9 are the same as the processes of steps S11 to S20a described with reference to FIG. The description is omitted.

After reading the article data in step SA1 (step SA1), the citation format setting unit 102s sets citation format (step SA2).

Here, the citation format setting process will be described. The citation format setting process is a process for setting a citation format, which is a standard when judging the legitimacy of citation in the article data. FIG. 27 is a flowchart of the citation format setting process.

As shown in FIG. 27, when the citation format setting process is activated, the output control unit 102h causes the display device 104 to output and display a citation format setting input screen (step SB1). FIG. 28 is a diagram exemplifying a citation format setting input screen. As shown in FIG. 28, in the citation format setting input screen, for example, a “type” menu for selecting the type of article data, a “citation format” box for inputting a legal citation format, and a storage location of a document regarded as legal A “law document storage location” box to be specified, a confirmation button for giving an instruction to confirm the input content on the citation format setting input screen, an end button for giving an instruction to end citation format setting, etc. are displayed.

Then, when the end instruction of the citation format setting process is instructed by pressing the end button via the input device 103 (Yes in step SB2), the citation format setting unit 102s ends the citation format setting process and returns to the main routine. . On the other hand, when the end button is not pressed and an instruction to end the citation format setting process is not issued (No in step SB2), the citation format determination unit selects the type of thesis data (for example, from the "type" menu) via the input device 103. It waits until "law" or "engineering" etc. is selected (step SB3, No), and when the type of article data is selected (step SB3, Yes), the selected type is temporarily stored in RAM etc. To do (step SB4).

Subsequently, the citation format setting unit 102 s stands by until the input content determination instruction is given by pressing the determination button via the input device 103 (step SB5, No), and the input content determination instruction is received (step SB5, Yes), storage of the document specified in the citation format (for example, "" "or" "" etc.) currently input in the "citation format" box, and "the legal document storage location" A place (for example, "Z: \ quotaion \ law \" or the like) is acquired, and stored in the quotation format DB 101 f in association with the type temporarily stored in the RAM or the like in step SB4 (step SB6). Thereafter, the process returns to step SB2, and it is determined whether an end instruction has been issued (step SB2).

Returning to the quotation determination support processing shown in FIG. 26, when the similarity calculated by the similarity calculation unit 102c in step SA7 is equal to or higher than the predetermined threshold in step SA8 (step SA8, Yes), the determination range is the comparison range. Judging that the document data and the like are cited, the legality determination unit 102e executes a legality determination process for determining whether the citation is a legal reference (step SA9).

(Process-legality judgment process)
Here, the legality determination process will be described. FIG. 29 is a flow chart showing the procedure of legality determination processing. When the legality determination process is activated, the legality determination unit 102e specifies the type of the article data to be determined (step SC1). For example, the type input screen (not shown) can be output and displayed on the display device 104, and the input of the type of article data to be determined can be received via the input device 103.

Next, the citation form DB 101 f is referred to based on the type specified in step SC 1, and a legal citation form corresponding to the type and a storage location of a document considered to be legal are acquired from the citation form DB 101 f (step SC 2).

Then, it is determined whether or not the citation which is determined in step SA8 that the reference data or the like in the comparison range is referred to is a citation conforming to the legal citation format acquired in step SC2 (step SC3). For example, when a proper citation form “” ”is used before or after a citation part, a citation part itself or a reference number to reference information indicating the citation source of the citation part immediately after the citation part is added If it is, or if the cited part is a citation from a document stored in the storage location of the document to be considered legal, it will be judged as a citation conforming to the legal citation form.

As a result, when it is determined that the content does not conform to the legal citation form (No in step SC3), the legality determination unit 102e causes the display device 104 to display an indication that the citation part is inappropriate. (Step SC4). For example, in the quotation determination screen shown in FIG. 7, it is assumed that the display of the cited part is reversed in black and white.

On the other hand, when it is determined that the document conforms to the legal citation form (step SC3, Yes), or after the process of step SC4, the legality determination unit 102e determines that the document data etc. in the comparison range is cited. It is determined whether a legitimacy determination has been made for all of the parts (step SC5).

As a result, when it is determined that the legality determination has not been performed for all of the cited parts (Step SC5, No), the legality determination unit 102e determines the legal citation form for the other cited parts for which the legality determination is not performed. It is determined whether or not the citation is in compliance with (step SC3). On the other hand, when it is determined that the legality determination has been performed for all of the quoted parts (Yes in step SC5), the legality determination unit 102e ends the legality determination process and returns to the main routine.

(effect)
Thus, in the quotation determination support apparatus 100 of the seventh embodiment, it is determined whether or not the determination range conforms to a predetermined citation form, and citation of the comparison range in the determination range is legal based on the determination result. Since it is determined whether or not it is a citation, the legitimacy of the citation can be easily determined based on a preset citation format.

In addition, since the citation form corresponding to the type of the article data is acquired from the citation form DB 101 f and it is determined whether the citation matches the acquired citation form, citation based on a citation form different for each type of the article data The legitimacy of can be determined.

Eighth Embodiment
An eighth embodiment will now be described. This form is a form which calculates the citation ratio which the description content quoted from the comparison range occupies among the description contents of the judgment range. However, the configuration and the process according to the eighth embodiment are the same as the configuration and the process according to the first embodiment except when particularly described, and the same configuration and the process in the first embodiment The description is abbreviate | omitted by using the same name or code | symbol as what was used as needed.

(Constitution)
FIG. 30 is a block diagram showing a functional configuration of the quotation decision support apparatus according to the eighth embodiment. The citation determination support apparatus 100 includes a citation ratio calculation unit 102t in the control unit 102 and a citation ratio DB 101g in the storage unit 101.

The citation ratio calculation unit 102t is a citation ratio calculation unit that calculates the citation ratio occupied by the description content cited from the comparison range among the description content of the determination range.

The quotation ratio DB 101 g is a quotation ratio storage unit that stores determination target data information that uniquely identifies determination target data and the quotation ratio calculated by the quotation ratio calculation unit 102 t in association with each other. FIG. 31 is a table exemplifying information stored in the citation ratio DB 101 g. As shown in FIG. 31, the citation ratio DB 101 g includes “thesis data information”, “document data information”, and “citation ratio” as data items, and information corresponding to these is stored in association with each other. The information stored in the item “dissertation data information” is determination target data information that uniquely identifies the dissertation data that is the determination target, and as shown in FIG. 31, for example, the student register number of the dissertation author and dissertation creation An identification number including a day is stored. The information stored in the item "document data information" is document data information that uniquely identifies the document data that is the citation source, and as shown in FIG. 31, for example, the document information of the document data is stored. The information stored in the item "quotation ratio" is information for specifying the citation ratio calculated by the citation ratio calculation unit 102t. As shown in FIG. 31, for example, the citation ratio of each document data in the article data And the numerical value which showed the total value of the said individual citation ratio in percentage is stored. The specific content of the citation ratio will be described later. These pieces of information are stored in the citation ratio DB 101 g in the citation determination support process described next.

(processing)
Next, processing executed by the quotation determination support apparatus 100 of the eighth embodiment configured as described above will be described. The processing executed by the quotation determination support apparatus 100 of the eighth embodiment is roughly classified into a quotation determination support processing and a list display processing.

(Processing-quote judgment support process)
First, the quote determination support process will be described. FIG. 32 is a flowchart showing the procedure of the quotation determination support process of the eighth embodiment. The processes in steps SD1 to SD11 are the same as the processes in steps S11 to S20a described with reference to FIG. 2 in the first embodiment, and thus detailed description will be omitted.

When it is determined in step SD11 that all the processing in steps SD5 to SD10 is completed for all the data in the specified comparison range (Yes in step SD11), the citation ratio calculation unit 102t determines that the description content of the determination range is The citation ratio occupied by the description content cited from the comparison range is calculated (step SD12). The specific content of the citation ratio is arbitrary, and for example, the percentage of the number of characters of the citation part to the number of characters of the determination range is calculated as the citation ratio.

Then, the output control unit 102h causes the display device 104 to output and display the citation ratio calculated by the citation ratio calculation unit 102t, and associates the calculated citation ratio with the article data information specifying the article data to be determined. The citation ratio DB 101g is stored (step SD13). When there are citations from a plurality of document data, the individual citation ratio occupied by the description content citation from each document data and the total value of the respective citation ratios are calculated and stored in the citation ratio DB 101 g.

FIG. 33 is a diagram exemplifying a quoting determination screen when the quoting ratio is displayed. In the example of FIG. 33, the citation ratio calculated as a percentage of the number of characters of the quoted portion to the number of characters of the determination range is displayed in the upper right portion of the citation determination screen. In addition, when the description content of the judgment range is cited from a plurality of document data, as shown in FIG. 33, the total value of the citation ratio from each document data and the individual citation ratio from each document data are displayed together You may make it display, and you may make it display only the total value of the citation ratio from each literature data.

(Process-list display process)
Next, the list display process will be described. This list display process is a process of outputting article data information in the order based on the citation ratio of each article data. FIG. 34 is a flowchart showing the procedure of the list display process. The execution timing of the list display process is arbitrary, and is started, for example, when an instruction to execute the list display process is input via the input device 103.

When the list display process is activated, the output control unit 102h acquires the total value of all the article data information and the corresponding citation ratio from the citation ratio DB 101g (step SE1). Subsequently, the output control unit 102h sorts the acquired article data information in the descending order of the total value of the corresponding citation ratios, and causes the display device 104 to output and display the data (step SE2). FIG. 35 is a diagram showing a determination result screen displaying a list of article data information in descending order of the total value of the citation ratio. As shown in FIG. 35, thesis data information is displayed on the screen in descending order of the citation ratio. At this time, an individual citation ratio for each document data may be displayed together for each article data information.

(effect)
As described above, the quotation decision support apparatus 100 of the eighth embodiment calculates and outputs the citation ratio occupied by the description content cited from the comparison range among the description contents of the judgment range, and therefore the judgment material of the legitimacy of the quotation is Can be presented.

In addition, citation ratios are calculated for multiple article data, and article data information is output in the order based on the citation ratio for each article data, so that legality of citations in multiple article data is compared based on the citation proportions. It is possible to present the judgment material of

[Embodiment 9]
A ninth embodiment will now be described. This form is a form that determines whether citation source information that specifies document data that is a citation source of a citation part is included in the determination target data. However, the configuration and the process according to the ninth embodiment are the same as the configuration and the process according to the first embodiment except when particularly described, and the same configuration and the process in the first embodiment The description is abbreviate | omitted by using the same name or code | symbol as what was used as needed.

(Constitution)
FIG. 36 is a block diagram showing a functional configuration of the quotation decision support apparatus according to the ninth embodiment. The quotation determination support apparatus 100 includes an output mode DB 101 h in the storage unit 101.

The output mode DB 101 h is an output mode information storage unit that stores the degree of similarity of the determination range and the output mode by the display device 104 in association with each other. FIG. 37 is a table exemplifying information stored in the output mode DB 101 h. As shown in FIG. 37, the output mode DB 101 h includes “similarity S [%]” and “output mode” as data items, and information corresponding to these is stored in association with each other. The information stored corresponding to the item "Similarity S [%]" is information for specifying the similarity of the determination range, and information for specifying the range of the similarity serving as the reference for the quotation determination (in FIG. 37, " 0 ≦ S <20 ”,“ 20 ≦ S <80 ”, etc. are stored. Although the range of similarity is divided into three levels in FIG. 37, it may be divided into two levels, or four or more levels. The information stored corresponding to the item “output mode” is information for specifying the output mode by the display device 104, and information for specifying the mode to be output according to the degree of similarity is stored. In the example of FIG. 37, when the similarity is less than 20%, the character output mode is “normal” because the possibility of citation is considered low, and when the similarity is 20% or more and less than 80%, the citation is Since there is a possibility, the output mode of the character is "bold", and when the similarity is 80% or more, the output mode of the character is "reverse" because the possibility of quoting is high. Further, the item “output mode” may store color information specifying a character color or a background color of a character, font information specifying a font of a character, and the like. The storage method and storage timing of the information stored in the output aspect DB 101 h can be arbitrarily stored in the output aspect DB 101 h via, for example, the input device 103 in advance.

(processing)
Next, the citation determination support process executed by citation determination support apparatus 100 of the ninth embodiment configured as described above will be described. FIG. 38 is a flowchart of the quotation determination support process of the ninth embodiment. Steps SF1, step SF5, step SF8, step SF9, step SF12, and steps SF15 to SF17 are the steps S11, S14, S15, and S16 described with reference to FIG. 2 in the first embodiment, respectively. Steps S18 and S19 to S20a are the same as the processes described above, and thus detailed description will be omitted.

After reading the article data in step SF1 (step SF1), the output control unit 102h causes the display device 104 to output and display the article data (step SF2). FIG. 39 is a diagram showing article data displayed on the citation determination screen on the display device 104. As shown in FIG. In the example shown in FIG. 39, the output control unit 102h causes the paper data display area 105, the range setting slider 106, the entire view 107, and the document data display area 108 to be displayed on the quotation determination screen. The paper data display area 105 is an area for displaying paper data to be judged. The range setting slider 106 sets a determination range in the article data to be determined, and an area sandwiched between the upper range setting slider 106 a and the lower range setting slider 106 b is set as the determination range. The whole view 107 is an area for displaying the display range of the paper data display area 105, the judgment range, and the approximate position of the cited part in the whole of the paper data to be judged. The document data display area 108 is an area for displaying the content of the cited document data. As shown in FIG. 39, in step SF2, the contents of the article data are displayed in the article data display area 105, and the display range of the article data display area 105 is displayed in the entire view 107 as a rectangular frame.

Referring back to FIG. 38, the determination range specifying unit 102a determines whether an instruction input of the determination range is input through the input device 103 (step SF3), and determines that an instruction input of the determination range is input (step SF3). , Yes), the range instructed by the instruction input is specified as the determination range (step SF4). In the example shown in FIG. 39, the range between the upper and lower range setting sliders 106 among the article data to be determined is specified as the determination range. In addition, as illustrated in FIG. 39, the output control unit 102h causes the region outside the determination range to be displayed by hatching in the entire view 107.

Referring back to FIG. 38, after the comparison range is specified in step SF5, the document reference determination unit 102d determines whether the threshold of similarity is input through the input device 103 (step SF6), and the similarity When it is determined that the threshold is input (Yes in step SF6), the document reference determination unit 102d sets the input threshold as a threshold of similarity in the reference determination (step SF7). In addition, the input method of a threshold is arbitrary, for example, an input box of a threshold can be displayed on a quotation determination screen (illustration omitted), and the numerical value input into the said input box via the input device 103 can be set as a threshold. . Alternatively, a threshold setting slider may be displayed on the quotation determination screen (not shown), and a value corresponding to the position of the setting slider whose position has been changed via the input device 103 may be set as the threshold.

After the similarity calculation unit 102c calculates the similarity in step SF9 (step SF9), the output control unit 102h acquires an output mode corresponding to the calculated similarity from the output mode DB 101h (step SF10), The determination range is output and displayed on the display device 104 based on the acquired output mode (step SF11). In the example of FIG. 39, the characters in the article data display area 105 are displayed based on the output aspect acquired from the output aspect DB 101 h illustrated in FIG. 37 corresponding to the calculated similarity. That is, a portion with a similarity of less than 20% is displayed normally, a portion with a similarity of 20% or more and less than 80% is displayed in bold, and a portion with a similarity of 80% or more is displayed in reverse. In addition, a portion having a similarity of 20% or more is hatched by cross lines in the entire view 107. This makes it possible for the user to roughly grasp the range occupied by the part that can be cited in the entire article data.

Referring back to FIG. 38, when it is determined in step SF12 that the citation of the determination range is not a legitimate citation by the legality determination unit 102e (No in step SF12), the citation determination unit 102e determines that the citation is not legal. It is determined whether the citation source information specifying the document data which is the citation source of the part is included in the article data to be determined (step SF13). The specific content of the citation source information is optional. For example, information such as the author name of the citation source document, year of publication, title, published magazine, number of volumes, location page, etc. can be used as the citation source information. In addition, a criterion for determining whether or not citation source information is included is optional, for example, whether citation source information is described immediately after the citation, or in a note number described immediately after the citation. Correspondingly, determination can be made based on whether citation information is described at the end of the article data.

As a result, when it is determined that citation source information is included in the article data to be determined (Yes in step SF13), the output control unit 102h causes the display device 104 to output and display the citation source information (step SF14). . The method and procedure for causing the display device 104 to output and display the quotation source information are arbitrary, and for example, an instruction input to display the quotation source information corresponding to the citation portion determined not to be a legal quotation is input via the input device 103 If it does, the citation source information corresponding to the citation part is displayed. In addition, when there are a plurality of citation parts determined not to be a legal citation, the citation source information corresponding to the citation part selected from among the plurality of citation parts is displayed by an instruction input via the input device 103. . FIG. 40 is a diagram showing a quotation determination screen on which quotation source information is displayed. As shown in FIG. 40, in the thesis data display area 105 of the citation determination screen, the citation source information corresponding to the designated citation portion (“○○○, ΔΔΔ at the bottom of the displayed paper data Δ, “××××××”, □□ magazine, Volume O, Δ page − Δ page ”portion is highlighted (in FIG. 40, inverted display).

After displaying the citation source information in this way (step SF14), or when it is determined in step SF13 that the citation source information is not included in the article data (step SF13, No), the reference information acquisition unit 102f references the reference information. It acquires (step SF15).

(effect)
As described above, in the quotation determination support apparatus 100 of the ninth embodiment, it is determined whether or not the citation source information specifying the document data which is the citation source of the citation part is included in the article data. It is possible to obtain judgmental materials in determining the legitimacy of citation based on

In addition, since the range designated via the input device 103 is specified as the determination range from the article data, it is possible to limit the target for which the quotation determination is performed, and to reduce the load associated with the determination process.

In addition, when the similarity is equal to or greater than the predetermined threshold input through the input device 103, it is determined that the determination range refers to the comparison range, so an optimum threshold is set according to the purpose of the determination. The determination based on the threshold can be performed.

In addition, since the output mode corresponding to the similarity calculated by the similarity calculation unit 102c is acquired from the output mode DB 101h, and the determination range is output in the acquired output mode, the user can easily grasp the similarity. The judgment range can be output with.

Tenth Embodiment
A tenth embodiment will now be described. In this embodiment, when citation source information specifying document data is included in the determination target data, it is determined that the document data specified based on the citation source information is stored in the document data storage unit The document data is specified as a comparison range. However, the configuration and processing according to the tenth embodiment are the same as the configuration and processing according to the first embodiment except when particularly described, and the same configuration and processing in the first embodiment The description is abbreviate | omitted by using the same name or code | symbol as what was used as needed.

(Processing-quote judgment support process)
A quote determination support process executed by the quote determination support apparatus 100 of the tenth embodiment will be described. FIG. 41 is a flowchart of the quotation determination support process of the tenth embodiment. The processes of steps SG1 to SG12 excluding step SG11 are the same as the processes of steps S11 to S20a described with reference to FIG. 2 in the first embodiment, and thus detailed description will be omitted. .

In step SG10, after the reference data and the like are explicitly cited in the determination range and the reference information is displayed (step SG10), the comparison range specification unit 102b displays the cited reference data. The bibliographic information (for example, author name, publication year, title, publication magazine, URL, etc.) of the document data and the storage location (for example, folder name) of the document data are stored in the document list while being stored in the document data storage unit 101a. The information is stored in the unit 101b (step SG11). Thereafter, it is determined whether or not the processing from step SG5 to step SG11 has been executed for all the data in the specified comparison range (step SG12).

(Process-comparison range identification process)
Here, the comparison range identification process executed in step SG4 of the quote determination support process will be described. FIG. 42 is a flowchart showing the procedure of the comparison and determination process of the tenth embodiment. The processes in steps SH5 to SH7 are the same as the processes in steps S21 to S23 described with reference to FIG. 6 in the first embodiment, and thus detailed description will be omitted.

When the comparison range identification process is activated, the comparison range identification unit 102b identifies the document data cited in the article data based on the result of the structural analysis of the article data performed in step SG2 of the quotation determination support process. It is determined whether the citation source information is included in the article data (step SH1).

As a result, when the citation source information is included (step SH1, Yes), the comparison range specification unit 102b refers to the document list storage unit 101b, and bibliographic information corresponding to the citation source information is stored in the document list storage unit 101b. It is determined whether or not it is stored (step SH2). As a result, when bibliographic information is stored in the document list storage unit 101b (Yes in step SH2), the comparison range specification unit 102b stores the documents stored in the storage location stored in association with the bibliographic information. The data is read from the document data storage unit 101a (step SH3), and the read document data is specified as a comparison range (SH4).

On the other hand, when it is determined in step SH1 that citation source information is not included in the article data (No in step SH1), or in step SH2, bibliographic information corresponding to the citation source information is not stored in the document list storage unit 101b. If it is determined that the result is (step SH2, No), the comparison range specification unit 102b reads all the thesis data submitted in the past stored in the thesis data storage unit 101c (step SH5).

After the process of step SH4 or step SH7, the comparison range specifying unit 102b ends the comparison range specifying process and returns to the main routine.

(effect)
Thus, in the quotation determination support apparatus 100 of the tenth embodiment, the document data storage unit 101 a stores the document data determined by the document quotation determination unit 102 d as being cited in the determination range. In addition, when citation source information that specifies document data is included in the article data, when it is determined that the document data specified based on the citation source information is stored in the document data storage unit 101a, Identify literature data as a comparison range. As a result, the comparison range can be limited to the document data already stored in the document data storage unit 101a, and the load in searching the content of the determination range from the data of the comparison range can be reduced.

[Modification 1 to Embodiment 6]
Although the embodiments according to the present invention have been described above, the specific configuration and means of the present invention can be modified and improved arbitrarily within the scope of the technical idea of each invention described in the claims. be able to. Hereinafter, such a modified example will be described.

In the sixth embodiment, the similarity calculation unit 102r performs processing when the character string of the search key exceeds the limited number of characters, but performs processing so that the character string designated as the search key does not exceed the limited number of characters in advance. You can also

That is, in the similarity calculation unit 102r, the determination range is analyzed by text mining processing using morphological analysis etc. and divided into words of a character string less than the limited number of characters, and a word appearing a predetermined number or more is designated as a search key Search multiple times from the comparison range for each word. Then, the similarity calculation unit 102r is a target of a comparison range for calculating the similarity between the comparison range of the search result whose appearance frequency is larger than a predetermined value among the search results of a plurality of times and the description content of the determination range. It may be configured to be determined as

The similarity calculation process in the first modification will be described. FIG. 22 is a flowchart illustrating the procedure of the similarity calculation process of the first modification.

First, the similarity calculation unit 102r performs text mining processing such as morphological analysis on data of the description content of the determination range, and divides the data into words having the number of characters within the limited number of characters (step S111). Then, the similarity calculation unit 102r calculates the appearance frequency of each word (step S112), and sorts the words in descending order of appearance frequency (step S113). Then, the similarity calculation unit 102r designates a word with the highest appearance frequency as a search key (step S114).

Next, the similarity calculation unit 102r searches the comparison range with the designated search key (step S115), and stores the search result in the memory (step S116).

Next, the similarity calculation unit 102r determines whether the search process has been performed for all the words whose appearance frequency is a predetermined number or more (step S117). Then, when the similarity calculation unit 102 r determines that the search processing has not been performed on all the words having the appearance frequency of the predetermined number or more (No at step S 117), the word having the next highest appearance frequency is Designating as a search key (step S118), the search process of steps S115 and S116 is repeatedly executed.

On the other hand, when it is determined in step S117 that the similarity calculation unit 102r has completed the search processing for all the words having the appearance frequency of a predetermined number or more (Yes in step S117), a plurality of words stored in the memory The comparison range as the search result having the highest frequency of appearance among the search results of is selected (step S119). Thereby, the selected comparison range becomes an object of similarity calculation, and the similarity with the determination range is calculated.

As described above, according to the first modification of the sixth embodiment, a search result having a high appearance frequency is automatically specified, and this search result is automatically set as a comparison range used for similarity calculation. The comparison range that matches with can be extracted automatically and the citation determination can be performed, and the accuracy of the citation determination can be further improved. In addition, it is also possible to search in advance using words less than the limited number of characters from the description content of the determination range as the search key. In this case, the accuracy of the quotation determination can be improved regardless of the limited number of characters of the search key. it can.

As in the sixth embodiment, the similarity calculation is performed so that the process of this modification is performed only when an error notification that the number of characters of the search key exceeds the number of restricted characters is received from the search engine or the like. The unit 102r may be configured.

[Modification 2 to Embodiments 5 and 6]
In the sixth embodiment, when the similarity calculating unit 102r calculates the similarity between the determination range and the comparison range, processing is performed in the case where the search key exceeds the limited number of characters. The present invention can also be applied to the processing of the comparison range identification unit 102 q in the fifth embodiment.

That is, although the WEB page is searched using the task sentence extracted from the article data as a search key, in the case of a long sentence in which the task sentence exceeds the limited number of characters, the search engine etc. An error notification is sent. For this reason, when the comparison range specifying unit 102 q receives an error notification that the search key exceeds the number of restricted characters, like the similarity calculation unit 102 r of the sixth embodiment, among the extracted task sentences, A search key is specified by the character string for the limited number of characters, and the search is performed multiple times while shifting the character string of the task sentence as the search key. Then, the comparison range specification unit 102 q may be configured to determine the cited document data specified by the URL with the highest appearance frequency among the plurality of URLs output as the search result as the comparison range.

FIG. 23 is a flowchart illustrating the procedure of comparison range identification processing of the second modification. First, the task extracting unit 102p analyzes the structure of the article data as the determination target to extract task sentences (step S131). Next, the comparison range specifying unit 102 q searches for the corresponding WEB page from the WEB site 131 on the Internet 130, the file server 133, and the like using the extracted task sentence as a search key (step S132).

Then, the comparison range specifying unit 102 q determines whether an error notification that the search key has exceeded the limit number of characters has been received (step S 133).

When the error notification that the search key has exceeded the limit number of characters has not been received (step S133, No), the comparison range specifying unit 102q selects the URL of the search result (step S141), and Similar to the fifth aspect, the cited reference data specified by the URL of the search result is specified as the comparison range.

On the other hand, in step S133, when an error notification that the search key has exceeded the limited number of characters is received (Yes in step S133), the comparison range specifying unit 102q acquires the limited number of characters from the received error notification. (Step S134).

Then, the comparison range specifying unit 102q designates a character string of a range for the limited number of characters from the top of the task sentence as a search key (step S135), and searches the WEB page using this search key (step S136). The comparison range specifying unit 102 q stores the URL, which is the search result, in the memory (step S 137).

Then, the comparison range specifying unit 102q determines whether the final character string has been reached as a search key for the task sentence (step S138), and if it has not reached yet (step S138, No), Among them, a character string for the next limited number of characters is designated as a search key (step S139), and the processes of steps S136 and S137 are repeatedly executed.

On the other hand, when the final character string is reached as the search key of the task sentence in step S138 (step S138, Yes), the URL of the search result having the highest frequency of appearance among the URLs of the search results stored in the memory. Is selected (step S140), and cited reference data specified by the URL of the selected WEB page is specified as the comparison range.

Therefore, according to the second modification, when the search key exceeds the limited number of characters, the character string of the limited number of characters in the task sentence designates the search key, and the character string of the task sentence as the search key Since the search is performed several times while shifting the key, it is possible to specify an appropriate comparison range of cited reference data according to the content of the dissertation, regardless of the limited number of characters of the search key. It can be improved.

[Modification 3 to Embodiments 5 and 6]
Furthermore, the process as described in the first modification of the comparison range specifying unit 102q according to the fifth embodiment, that is, the task sentence is divided into words such that the character string specified in advance as a search key does not exceed the limited number of characters. Then, the search may be configured by specifying it as a search key.

[Modification to Embodiment 7]
In the above-described seventh embodiment, determination of the legitimacy of citation is performed for a portion where the similarity calculated by the similarity calculation unit 102 c is determined to be equal to or higher than a predetermined threshold. It may be configured to perform legality determination of For example, if the article data to be judged contains a reference symbol (for example, "", "", etc.) corresponding to the type of the article data, citation in the article data is legal. It may be configured to determine the effect. In addition, the file name of the thesis data may be output and displayed on the display device 104 in an output mode based on the determination result. For example, the file name of the article data whose citation is determined to be inappropriate may be displayed in reverse in black and white so as to be distinguishable from the file name of the article data determined to be appropriate.
