Next, a citation determination support process executed by the citation determination support apparatus 100 of the first embodiment configured as described above will be described. FIG. 2 is a flowchart illustrating a procedure of the citation determination support process according to the first embodiment.

  When the user instructs execution of the quotation determination support process by a predetermined method via the input device 103, first, a quotation determination screen is displayed on the display device 104 by the output control unit 102h. FIG. 3 is a schematic diagram illustrating an example of a citation determination screen. When the “simple” button is clicked on this screen, the determination range is specified. Clicking the “Details” button on the citation determination screen makes various settings for searching the search database for managing the document data in the document data storage unit 101a, the language, the generation period of the cited document data, keywords, creator, and the like. A screen (not shown) for performing is displayed.

  In order to specify the determination range, the determination range specifying unit 102a reads the created paper data from the paper data storage unit 101c (step S11). Then, the determination range specifying unit 102a performs structural analysis of the structure of the paper data by a known method (step S12), and introduces parts (such as "Introduction" constituent parts) constituting the paper, text part, final part, etc. ( “Finally”, “Acknowledgment” components, etc.). Since the body part is the main part of the article data and is a constituent part that is highly likely to cite a third-party document, the determination range specifying unit 102a selects the constituent part obtained by the structural analysis. The body part is specified as the determination range (step S13).

  FIG. 4 is an explanatory diagram showing an example of a body part specified as a determination range in the paper data. In the case of the report shown in FIG. 4, since the content described in the answer column is a component corresponding to the text, the determination range specifying unit 102a specifies the description content of the answer column as the determination range. . When the determination range is specified in this way, the output control unit 102h displays the contents of the specified determination range in the determination range column of the citation determination screen as shown in FIG.

  Returning to FIG. 2, when the determination range is specified, the user clicks the “execute search” button on the quotation determination screen shown in FIG. When the “execute search” button is clicked, the input control unit 102g receives the event, whereby the comparison range specifying unit 102b performs the comparison range specifying process (step S14).

  FIG. 6 is a flowchart showing the procedure of the comparison range specifying process. First, the comparison range specifying unit 102b reads all the paper data submitted in the past stored in the paper data storage unit 101c (step S21). Next, the comparison range specifying unit 102b reads all 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 paper data and the acquired document data (document data, etc.) as the comparison range (step S23).

  Returning to FIG. 2, when the comparison range is specified, the similarity calculation unit 102c searches for data in the specified comparison range using the description content of the specified determination range as a search key (step S15). The similarity of the description content is calculated (step S16). Specifically, the similarity calculation unit 102c causes a search program or search engine using a known search technique, or a search instruction to be executed by specifying a search key for these search program or search engine. Here, as the similarity calculation logic, for example, known logic such as syntactic analysis of the description contents of the determination range of the article data and the description contents of the document data, and quantification of the degree of coincidence of each word or phrase is used. . Then, the document citation determination unit 102d determines whether or not the determination range cites a document in the comparison range by determining whether or not the calculated similarity is equal to or greater than a predetermined threshold (step S17). ).

  If the calculated similarity is smaller than the predetermined threshold (No in step S17), it is determined that the determination range does not cite literature data in the comparison range, and the process ends. Here, the predetermined threshold value can be arbitrarily determined according to the accuracy required for citation determination.

  On the other hand, when the calculated similarity is equal to or greater than the predetermined threshold (Yes in step S17), it is determined that the determination range is cited from the comparison range document data, and then the legality determination unit 102e. It is determined whether this citation is a legal citation (step S18). Here, the citation “legal” is a concept including that the citation is legal under the Copyright Act, or that the user has preset requirements. Specifically, when the legality determination unit 102e has a display of the book name near the lower part of the citation part of the reference data or the like in the determination range, there is a display of parentheses “” indicating the citation immediately before and after the citation part. If the quoted portion is displayed in a font different from the fonts of other portions to indicate that it is a quoted portion, it is determined that the quoted portion is legally quoted based on the copyright law. In addition to this, when there is a predetermined indication (for example, author name, author name, or publisher name) that confirms the legality of the citation near the lower part of the citation location such as literature data, the citation location is You may make it judge that it was quoted legally.

  If it is determined that the citation in the determination range is a legal citation (step S18, Yes), the process ends.

  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 document data or the like (cited document data or cited paper data). It is acquired from the reference information (file name and title of document data, URL, folder name, etc.), the attribute of document data, the attribute of cited article data, etc. (step S19). Then, the output control unit 102h clearly indicates the part where the document data or the like is cited within the determination range on the quotation determination screen and displays the reference information (step S20).

  The processing from step S15 to S20 is repeatedly executed for all the data in the specified comparison range (No in step S20a). If the processing from step S15 to S20 has been executed for all the data in the specified comparison range (step S20a, Yes), the processing ends.

  In the present embodiment, the output control unit 102h first highlights a portion cited within the determination range by discoloration, inversion, or the like. FIG. 7 is a schematic diagram showing a state in which a quoted portion is highlighted within the determination range on the quote determination screen. In FIG. 7, the bold and underlined portion is the highlighted portion, that is, the quoted portion.

  Then, when the user instructs this citation location via the input device 103, the input control unit 102g accepts the instruction, and the output control unit 102h controls to display the reference information at the designated location. Yes.

  FIG. 8 is a schematic diagram showing a state in which the reference information is displayed on the citation determination screen. The example of FIG. 8 shows a case where 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 so as to display the citation source document data and the like. It is composed. This makes it possible for a professor or the like who makes a citation determination of article data to easily obtain the document data of the citation source.

  In the citation determination support apparatus 100 according to the first embodiment, the determination range specifying unit 102a specifies the text part that is easily cited without permission from the constituent parts constituting the article data. The accuracy can be further improved.

  Further, in the citation determination support apparatus 100 of the first embodiment, when it is determined that the determination range is quoting the comparison range, the legality determination unit 102e applies the reference range of the comparison range in the determination range and the vicinity thereof. Since it is determined whether or not the citation is a legal citation, it can be easily determined whether or not the citation of the document data is a legal citation prescribed in the Copyright Act. Accuracy can be improved.

  Moreover, in the quotation determination support apparatus 100 of Embodiment 1, the reference information acquisition unit 102f acquires reference information for referring to document data including a comparison range based on the document data, and compares the reference range of the document data. By outputting the reference information acquired in addition to the determination range of the determination target data quoting the document data, it is possible to easily refer to the document data.

If the similarity has not yet been reached (step S97, No), Among them, a character string corresponding to 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. Note that the specific method for specifying a character string for the limited number of characters is arbitrary, but as an example, a method of moving the limited number of characters as a unit (for example, when the limited number of characters = 32 characters) In the first, a character string from the first character to the 32nd character is used as a search key for the first time, and a character string from the 33rd character to the 64th character is used as a search key for the second time, and the search key is designated in the same manner. ), A method of moving one character unit (for example, in the case of the limit number of characters = 32 characters, the first character string is used as the search key from the first character to the 32nd character, and the second time is from the second character to the 33rd character) The search key is used as a search key, and the search key is designated in the same manner), or a method of moving by any number of characters (for example, when the limit number of characters = 32 characters and the number of arbitrary characters = 1). When using characters, the first character string from the first character to the 32nd character is used as the search key for the first time, and the character string from the 11th character to the 42nd character is used as the search key for the second time. Can be employed.

  On the other hand, if the last character string is reached as the determination range search key in step S97 (step S97, Yes), the search result with the highest appearance frequency is selected from the search results stored in the memory ( In step S99), the selected comparison range is a target of similarity calculation, and the similarity with the determination range is calculated.

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

[Embodiment 7]
Next, a seventh embodiment will be described. In this form, the legality determination means determines whether or not the determination range matches a predetermined citation format, and based on the determination result, whether or not the comparison range citation in the determination range is a legal citation. It is the form which determines whether. However, the configuration and processing according to the seventh embodiment are the same as the configuration and processing according to the first embodiment unless otherwise described, and the same configuration and processing are described in the first embodiment. The description is omitted by using the same name or symbol as used as necessary.

(Constitution)
FIG. 24 is a block diagram illustrating a functional configuration of the citation determination support apparatus according to the seventh embodiment. 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 102s is a citation format setting unit that sets a citation format that serves as a reference when the legality of citations is determined.

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

(Processing-Citation determination support processing)
Next, a citation determination support process executed by the citation determination support apparatus 100 according to the seventh embodiment configured as described above will be described. FIG. 26 is a flowchart illustrating a procedure of citation determination support processing according to the seventh embodiment. Each process from step SA1 to step SA13 excluding step SA2 and step SA9 is the same as each process from step S11 to step S20a described with reference to FIG. Description is omitted.

  After reading the article data in step SA1 (step SA1), the citation format setting unit 102s sets the 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 for determining the legality of citations in article data. FIG. 27 is a flowchart showing the procedure of the citation format setting process.

  As shown in FIG. 27, when the citation format setting process is activated, the output control unit 102h outputs and displays a citation format setting input screen on the display device 104 (step SB1). FIG. 28 is a diagram illustrating a citation format setting input screen. As shown in FIG. 28, on 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 “legitimate document storage location” box to be specified, a confirmation button for instructing confirmation of input contents on the citation format setting input screen, an end button for instructing termination of citation format setting, and the like are displayed.

  When the quit 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, if the end button is not pressed and the end instruction of the citation format setting process is not instructed (No in step SB2), the citation format determination unit uses the input device 103 to select the type of article data (for example, Wait until “Law” or “Engineering” is selected (step SB3, No), and when the type of paper data is selected (step SB3, Yes), the selected type is temporarily stored in the RAM or the like. (Step SB4).

  Subsequently, the citation format setting unit 102s waits until an input content confirmation instruction is issued by pressing the confirmation button via the input device 103 (step SB5, No), and when the input content confirmation instruction is issued (step SB5). SB5, Yes), the citation format (for example, "" "," "" ", etc.) entered in the" citation format "box at that time, and storage of the document specified by" legitimate document storage location " A location (for example, “Z: ¥ quotation ¥ law ¥”, etc.) is acquired, and stored in the citation format DB 101f 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 or not an end instruction has been issued (step SB2).

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

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

  Next, the citation format DB 101f is referred to based on the type specified in step SC1, and the legal citation format corresponding to the type and the storage location of the document regarded as legal are acquired from the citation format DB 101f (step SC2).

  Then, it is determined whether or not the citation determined that the document data or the like in the comparison range is cited in step SA8 is a citation based on the legal citation format acquired in step SC2 (step SC3). For example, when the legitimate citation format ““ ”” is used before and after the citation, or when the citation is itself or immediately after the citation, a reference number is added to the reference information indicating the citation source of the citation. If it is a citation from a document stored in the document storage location where the citation is considered legal, it is determined that the citation conforms to a legal citation format.

  As a result, when it is determined that it does not conform to the legal citation format (No in step SC3), the legality determination unit 102e causes the display device 104 to output and display a display indicating that the quoting part is illegal. (Step SC4). For example, in the citation determination screen shown in FIG.

  On the other hand, when it is determined that it conforms to the legal citation format (step SC3, Yes), or after the processing of step SC4, the legality determination unit 102e determines that it has cited the document data in the comparison range. It is determined whether or not legality determination has been performed for all of the portions (step SC5).

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

(effect)
As described above, the citation determination support apparatus 100 according to the seventh embodiment determines whether or not the determination range matches a predetermined citation format, and based on the determination result, the citation of the comparison range in the determination range is legal. Since it is determined whether or not it is a citation, it is possible to easily determine the legality of the citation based on a preset citation format.

  In addition, the citation format corresponding to the type of the paper data is acquired from the citation format DB 101f, and it is determined whether or not the citation matches the acquired citation format. The legality of can be determined.

[Embodiment 8]
Next, an eighth embodiment will be described. This form is a form in which the citation ratio occupied by the description content cited from the comparison range is calculated from the description content of the determination range. However, the configuration and processing according to the eighth embodiment are the same as the configuration and processing according to the first embodiment unless otherwise described, and the same configuration and processing are described in the first embodiment. The description is omitted by using the same name or symbol as used as necessary.

(Constitution)
FIG. 30 is a block diagram illustrating a functional configuration of the citation determination support apparatus according to the eighth embodiment. In the citation determination support apparatus 100, the control unit 102 includes a citation rate calculation unit 102t, and the storage unit 101 includes a citation rate DB 101g.

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

  The quotation ratio DB 101g is a quotation ratio storage unit that stores determination target data information for uniquely identifying determination target data and the quotation ratio calculated by the quotation ratio calculation unit 102t in association with each other. FIG. 31 is a table illustrating information stored in the citation ratio DB 101g. As shown in FIG. 31, the citation ratio DB 101g includes “article data information”, “literature 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 “thesis data information” is judgment target data information for uniquely identifying the judgment subject paper data, and as shown in FIG. An identification number including the 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. For example, document information of the document data is stored as illustrated in FIG. 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, individual citation ratios from each document data in the article data. And a numerical value indicating the total value of the individual citation ratios as a percentage. The specific content of the quoting ratio will be described later. These pieces of information are stored in the quotation ratio DB 101g in the quotation determination support process described below.

(processing)
Next, processing executed by the quotation determination support apparatus 100 according to Embodiment 8 configured as described above will be described. The processes executed by the quotation determination support apparatus 100 according to the eighth embodiment are roughly classified into a quotation determination support process and a list display process.

(Processing-Citation determination support processing)
First, the quotation determination support process will be described. FIG. 32 is a flowchart illustrating the procedure of the citation determination support process according to the eighth embodiment. Since each process from step SD1 to step SD11 is the same as each process from step S11 to step S20a described with reference to FIG. 2 in the first embodiment, detailed description thereof is omitted.

  In step SD11, when it is determined that the processing from steps SD5 to SD10 has been completed for all of the specified comparison range data (step SD11, Yes), the citation ratio calculation unit 102t includes the description contents of the determination range. Then, the quoting ratio occupied by the description content quoted from the comparison range is calculated (step SD12). The specific content of the quoting ratio is arbitrary. For example, the percentage of the number of characters in the citation portion with respect to the number of characters in the determination range is calculated as the quoting ratio.

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

  FIG. 33 is a diagram exemplifying a citation determination screen when the citation ratio is output and displayed. In the example of FIG. 33, the quoting ratio calculated as a percentage of the number of characters in the citation part with respect to the number of characters in the determination range is displayed in the upper right part of the citation determination screen. In addition, when the description contents of the judgment range are 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. Only the total value of the citation ratios from each document data may be displayed.

(Processing-List display processing)
Next, list display processing will be described. This list display process is a process of outputting the 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 activated when, for example, 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 descending order of the total value of the corresponding citation ratios, and outputs and displays them on the display device 104 (step SE2). FIG. 35 is a diagram illustrating a determination result screen that displays a list of article data information in descending order of the total citation ratio. As shown in FIG. 35, the article data information is displayed on the screen in descending order of the citation rate. At this time, individual citation ratios for each document data may be displayed together for each piece of paper data information.

(effect)
As described above, the citation determination support apparatus 100 according to the eighth embodiment calculates and outputs the citation ratio occupied by the description content quoted from the comparison range in the description content of the determination range. Can be presented.

  In addition, the citation ratio is calculated for multiple paper data, and the paper data information is output in the order based on the citation ratio for each paper data, so that the legality of citations in multiple paper data can be compared based on the citation ratio. The judgment materials can be presented.

[Embodiment 9]
Next, Embodiment 9 will be described. This form is a form in which it is determined whether or not the citation source information that identifies the document data that is the citation source of the cited part is included in the determination target data. However, the configuration and processing according to the ninth embodiment are the same as the configuration and processing according to the first embodiment unless otherwise described, and the same configuration and processing are described in the first embodiment. The description is omitted by using the same name or symbol as used as necessary.

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

  The output mode DB 101h is output mode information storage means for storing the similarity of the determination range and the output mode by the display device 104 in association with each other. FIG. 37 is a table illustrating information stored in the output mode DB 101h. As shown in FIG. 37, the output mode DB 101h includes “similarity S [%]” and “output mode” as data items, and information corresponding to these items is stored in association with each other. The information stored corresponding to the item “similarity S [%]” is information that specifies the similarity of the determination range, and information that specifies the range of similarity that serves as a reference for citation determination (in FIG. 37, “ 0 ≦ S <20 ”,“ 20 ≦ S <80 ”, etc.) are stored. In FIG. 37, the range of similarity is divided into three stages, but it may be divided into two stages or four or more stages. The information stored corresponding to the item “output mode” is information for specifying the output mode by the display device 104, and stores information for specifying the mode to be output according to the degree of similarity. In the example of FIG. 37, since it is considered that the possibility of citation is low when the similarity is less than 20%, the character output mode is “normal”, and when the similarity is 20% or more and less than 80%, Since there is a possibility, the character output mode is “bold”, and when the similarity is 80% or more, the character output mode is “inverted” because the possibility of citation is high. In addition, the item “output mode” may store color information specifying the character color and the background color of the character, font information specifying the font of the character, and the like. The storage method and the storage timing of the information stored in the output mode DB 101h are arbitrary, and can be stored in the output mode DB 101h via the input device 103 in advance, for example.

(processing)
Next, a citation determination support process executed by the citation determination support apparatus 100 of Embodiment 9 configured as described above will be described. FIG. 38 is a flowchart illustrating the procedure of the citation determination support process according to the ninth embodiment. Note that step SF1, step SF5, step SF8, step SF9, step SF12, and step SF15 to step SF17 are respectively step S11, step S14, step S15, and step S16 described with reference to FIG. 2 in the first embodiment. , Step S18 and Step S19 to Step S20a are the same as the respective processes, and detailed description thereof is omitted.

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

  Returning to FIG. 38, the determination range specifying unit 102a determines whether or not a determination range instruction is input via the input device 103 (step SF3), and determines that a determination range instruction is input (step SF3). , Yes), the range specified 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 in the paper data to be determined is specified as the determination range. In addition, as illustrated in FIG. 39, the output control unit 102h displays an area outside the determination range by hatching in the overall view 107.

  Returning to FIG. 38, after the comparison range is specified in step SF5, the document citation determination unit 102d determines whether or not a similarity threshold value is input via the input device 103 (step SF6). When it is determined that a threshold value has been input (step SF6, Yes), the document citation determination unit 102d sets the input threshold value as a similarity threshold value in citation determination (step SF7). The threshold value input method is arbitrary. For example, a threshold value input box can be displayed on the citation determination screen (not shown), and a numerical value input to the input box via the input device 103 can be set as the threshold value. . Alternatively, a threshold setting slider can 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 can 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). Based on the acquired output mode, the determination range is output and displayed on the display device 104 (step SF11). In the example of FIG. 39, characters in the paper data display area 105 are displayed based on the output mode acquired from the output mode DB 101h 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 highlighted. In addition, a portion having a similarity of 20% or more is displayed by crossing hatching in the overall view 107. As a result, the user can roughly grasp the range occupied by the portion that may be cited in the entire paper data.

  Returning to FIG. 38, when the legality determination unit 102e determines in step SF12 that the citation of the determination range is not a legal citation (No in step SF12), the legality determination unit 102e determines that the citation is not legal. It is determined whether or not the citation source information that identifies the document data that is the citation source of the portion is included in the paper data to be determined (step SF13). The specific content of the citation source information is arbitrary. For example, information such as the author's name, publication year, title, publication magazine, number of volumes, and location page of the citation source information can be used as the citation source information. In addition, the criterion for determining whether or not the citation source information is included is arbitrary. For example, whether or not the citation source information is described immediately after the citation location, or the note number described immediately after the citation location is indicated. Correspondingly, the determination can be made based on whether or not the citation information is described at the end of the article data.

  As a result, when it is determined that the citation source information is included in the paper data to be determined (step SF13, Yes), the output control unit 102h outputs and displays the citation source information on the display device 104 (step SF14). . The method and procedure for outputting and displaying the citation source information on the display device 104 is arbitrary. For example, an instruction input for displaying the citation source information corresponding to the citation portion determined not to be a legal citation is input via the input device 103. If it is, the citation source information corresponding to the citation part is displayed. Further, when there are a plurality of citation parts determined not to be legal citations, the citation source information corresponding to the citation part selected from the plurality of citation parts is displayed by an instruction input via the input device 103. . FIG. 40 is a diagram illustrating a citation determination screen on which citation source information is displayed. As shown in FIG. 40, in the article data display area 105 of the citation determination screen, the citation source information corresponding to the designated citation part (“XXXXX, △△△ at the bottom of the displayed article data) is displayed. Δ, “XXX × XXX”, □□ Magazine, Vol. ○, △ Page- □ Page ”) is highlighted (inverted display in FIG. 40).

  After the citation source information is displayed in this way (step SF14), or when it is determined in step SF13 that the citation source information is not included in the paper data (step SF13, No), the reference information acquisition unit 102f displays the reference information. Obtain (step SF15).

(effect)
As described above, in the citation determination support apparatus 100 according to the ninth embodiment, since it is determined whether or not the citation source information for identifying the document data that is the citation source of the citation portion is included in the paper data, the presence or absence of the citation source information. Based on the above, it is possible to obtain a judgment material for judging the legality of the citation.

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

  In addition, when the similarity is equal to or higher than a predetermined threshold value input via the input device 103, it is determined that the determination range refers to the comparison range. Therefore, an optimal threshold value is set according to the purpose of the determination. The determination based on the threshold value can be performed.

  Moreover, 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 mode in which the user can easily grasp the similarity Can output the judgment range.

[Embodiment 10]
Next, Embodiment 10 will be described. In this form, when the citation source information for specifying the 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 In this mode, 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 unless otherwise described, and the same configuration and processing are described in the first embodiment. The description is omitted by using the same name or symbol as used as necessary.

(Processing-Citation determination support processing)
A citation determination support process executed by the citation determination support apparatus 100 of the tenth embodiment will be described. FIG. 41 is a flowchart illustrating the procedure of the citation determination support process according to the tenth embodiment. Since each process from step SG1 to step SG12 excluding step SG11 is the same as each process from step S11 to step S20a described with reference to FIG. 2 in the first embodiment, detailed description thereof is omitted. .

  In step SG10, after clearly showing on the citation determination screen the portion where the document data or the like is cited within the determination range, and displaying the reference information (step SG10), the comparison range specifying unit 102b converts the cited document data. The bibliographic information (for example, author name, publication year, title, published 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. Store 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).

(Processing-Comparison range identification processing)
Here, the comparison range specifying process executed in step SG4 of the citation determination support process will be described. FIG. 42 is a flowchart illustrating a comparison determination process according to the tenth embodiment. Since each process from step SH5 to step SH7 is the same as each process from step S21 to step S23 described with reference to FIG. 6 in the first embodiment, detailed description thereof is omitted.

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

  As a result, when the citation source information is included (step SH1, Yes), the comparison range specifying unit 102b refers to the document list storage unit 101b, and the 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 the bibliographic information is stored in the document list storage unit 101b (step SH2, Yes), the comparison range specifying unit 102b stores the document stored in the storage location stored in association with the bibliographic information. 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 the citation information is not included in the paper data (step SH1, No), or bibliographic information corresponding to the citation information is not stored in the document list storage unit 101b in step SH2. (Step SH2, No), the comparison range specifying unit 102b reads all the paper data submitted in the past stored in the paper 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.

Although the embodiments of the present invention have been described above, the specific configuration and means of the present invention are arbitrarily modified and improved within the scope of the technical idea of each invention described in the claims. be able to. Hereinafter, such a modification 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 specified in advance as the search key does not exceed the limited number of characters. You can also

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

  The similarity calculation process in Modification 1 will be described. FIG. 22 is a flowchart illustrating a procedure of similarity calculation processing according to the first modification.

  First, the similarity calculation unit 102r performs text mining processing such as morphological analysis on the data of the description contents in the determination range, and divides the data into words having a number of characters within the limited number of characters (step S111). Then, the similarity calculation unit 102r calculates the appearance frequency for 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 having the highest appearance frequency as a search key (step S114).

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

  Next, the similarity calculation unit 102r determines whether or not a search process has been performed for all words having an appearance frequency equal to or greater than a predetermined number (step S117). If the similarity calculation unit 102r determines that the search processing has not yet been performed for all the words having the appearance frequency equal to or greater than the predetermined number (No in step S117), the word having the next highest appearance frequency is selected. The search key is designated (step S118), and the search processing of steps S115 and S116 is repeatedly executed.

  On the other hand, in step S117, when the similarity calculation unit 102r determines that the search processing has been completed for all words having an appearance frequency equal to or greater than the predetermined number (step S117, Yes), the similarity calculation unit 102r stores a plurality of items stored in the memory. The comparison range as the search result having the highest appearance frequency is selected from the search results (step S119). As a result, the selected comparison range becomes a target 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. It is possible to automatically extract a comparison range that matches the above and perform citation determination, thereby further improving the accuracy of citation determination. In addition, it is possible to perform a search in advance using a search key with words that are equal to or less than the limit number of characters in the description contents of the determination range. it can.

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

[Modification 2 to Embodiments 5 and 6]
In the sixth embodiment, when the similarity calculation unit 102r calculates the similarity between the determination range and the comparison range, the process is performed when the search key exceeds the limit number of characters. It can also be applied to the processing of the comparison range specifying unit 102q in the fifth embodiment.

  In other words, the WEB page is searched using the assignment sentence extracted from the article data as a search key. However, if the assignment sentence is a long sentence exceeding the limit number of characters, the search engine explained in the sixth embodiment. An error notification is sent. For this reason, when the comparison range specifying unit 102q receives an error notification that the search key exceeds the limit number of characters, the comparison range specifying unit 102q, in the extracted task sentence, similarly to the similarity calculation unit 102r of the sixth embodiment. A search key is designated by a character string corresponding to the limit number of characters, and a search is performed a plurality of times while shifting the character string of the task sentence as the search key. Then, the comparison range specifying unit 102q may be configured to determine the cited document data specified by the URL with the highest appearance frequency from the plurality of URLs output as the search results as the comparison range.

  FIG. 23 is a flowchart illustrating a procedure of comparison range specifying processing according to the second modification. First, the task extraction unit 102p performs structural analysis on the paper data that is a determination target, and extracts a task sentence (step S131). Next, the comparison range specifying unit 102q searches for a corresponding WEB page from the WEB site 131, the file server 133, or the like on the Internet 130 using the extracted task sentence as a search key (step S132).

  Then, the comparison range specifying unit 102q determines whether or not an error notification indicating that the search key exceeds the limit number of characters has been received (step S133).

  If the error notification indicating that the search key exceeds the limit number of characters has not been received (step S133, No), the comparison range specifying unit 102q selects the search result URL (step S141), and As in the fifth aspect, the cited document data specified by the URL of the search result is specified as the comparison range.

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

  Then, the comparison range specifying unit 102q designates a character string in the range of the limited number of characters from the beginning of the task sentence as a search key (step S135), and searches the WEB page with this search key (step S136). The comparison range specifying unit 102q stores the URL that is the search result in the memory (step S137).

  Then, the comparison range specifying unit 102q determines whether or not the final character string has been reached as the assignment key for the assignment sentence (step S138), and if it has not been reached yet (step S138, No), Among them, a character string corresponding to 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, in step S138, when the final character string is reached as the search key for the task sentence (step S138, Yes), the URL of the search result with the highest appearance frequency among the search result URLs stored in the memory. Is selected (step S140), and the cited document data designated 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 limit number of characters, the search key is specified by a character string corresponding to the limit number of characters in the task sentence, and the character string of the task sentence as the search key Since the search is performed multiple times while shifting, it is possible to specify an appropriate comparison range of cited reference data according to the content of the article data, regardless of the limited number of characters in the search key, and to improve the accuracy of citation determination. Can be improved.

[Modification 3 with respect to Embodiments 5 and 6]
Further, the comparison range specifying unit 102q according to the fifth embodiment performs processing as described in the first modification, that is, the task sentence is divided into words so that the character string designated as a search key in advance does not exceed the limit number of characters. Then, the search may be performed by designating it as a search key.
