A combination of “inventor” = “Sumio Fujita” in which the information 342A2 “Sumio Fujita” is set as an attribute, or “application” in which the attribute information 342A2 “○ □ × △” is set and input in the attribute item information 342A1 “applicant” For example, a combination of “applicant” = “◯ □ × Δ” in which attribute information 342A2 “◯ □ × Δ” is set as an attribute for “person”. The relevance level 1 information 343A3 is information regarding the relevance level of the combination of the attribute set 1 information 343A1 and the attribute set 2 information 343A2, that is, information regarding the relevance level of the attribute information 342A2 in different attribute items. For example, when different attribute items are Ai and Ak and the attributes of the attribute information 342A2 serving as the instance variables are Vj and Vl, the server processing unit 350 performs the association degree MI (Ai = Vj; Ak =) as follows. Vl) is calculated. That is, when different attribute items are Ai and Ak and the attributes of the attribute information 342A2 serving as the instance variables are Vj and Vl, the following Expression 4 is obtained.

(Equation 4)
p (Ak = Vl | Ai = Vj) = p (Ak = Vl ^ Ai = Vj) / p (Ak = Vl)
p (Ai = Vj | Ak = Vl) = p (Ak = Vl ^ Ai = Vj) / p (Ai = Vj)
MI (Ai = Vj; Ak = Vl)
= Log (p (Ak = Vl ^ Ai = Vj) / (p (Ai = Vj) * p (Ak = Vl))

  In this way, when the attribute information 342A2 that is different instance items are Ai and Ak and the attributes of the attribute information 342A2 are Vj and Vl, respectively, since Equation 4 is obtained, based on the attribute group information list table storage area 342, freq (Ai = Vj) and freq (Ak = Vl) are obtained. Further, freq (Ak = Vl ^ Ai = Vj) is the number of detected document information 341A in which the attribute item is Ai, Ak and the attribute information 342A2 has the attribute Vj, Vl. Therefore, f (Ak = Vl ^ Ai = Vj), which is the number of documents, is divided by the total number of document information 341A stored in the document information storage area 341, so that p (Ak = Vl ^ Ai = Vj) is obtained. Calculated. Thus, a pair of Ak = Vl and Ai = Vj in which the calculated relevance degree MI (Ai = Vj; Ak = Vl) is equal to or greater than a predetermined threshold is set as relevance degree 1 information 343A3. When Ai = Aj is attribute group 1 information 343A1 and Ak = Vl is attribute group 2 information 343A2, the value of p (Ak = Vl ^ Ai = Vj) calculated previously is set as relevance level 2 information 343A4. To do. Further, the value of p (Ak = Vl | Ai = Vj) is set as the relevance 3 information 343A5.

That is, the terminal device 200 notifies the terminal device 200 of various information for setting a keyword as a search condition at the time of document search, and controls the search means to perform a document search based on the set search condition. This search support means 352 includes search request information acquisition means 352A that also functions as keyword recognition means, information amount recognition means 352B, entropy recognition means 352C, relevance recognition means 352D, display control means 352E, and search control. Means 352F.

  The search request information acquisition unit 352A acquires search request information transmitted from the terminal device 200 and requesting the execution of a document search via the server communication unit 310. Then, the search request information acquisition unit 352A acquires attribute information 342A2 included in the search request information as a keyword. The acquired keyword is appropriately stored in the server storage unit 340. Further, the search request information acquisition unit 352A acquires information presentation request information for requesting presentation of information related to the attribute information 342A2 set and input as a keyword.

  The information amount recognition unit 352B recognizes the information amount of the keyword acquired by the search request information acquisition unit 352A, that is, the information amount of the attribute information 342A2 set as the keyword. This information amount is recognized by searching the attribute group information 342A having the same attribute information 342A2 based on the attribute group information list table storage area 342 and reading the information amount information 342A3 of the attribute group information 342A. . The recognized information amount information 342A3 is associated with the attribute information 342A2 that has been set and input, and is appropriately stored in the server storage unit 340. When the information amount recognition unit 352B cannot read the information amount information 342A3 by the search based on the attribute group information list table storage area 342, the document information 341A associated with the attribute information 342A2 set and input is obtained. It is determined that the document information is not stored in the document information storage area 341, and that is associated with the attribute information 342 A 2 that has been set and input, and stored in the server storage unit 340 as appropriate.

  The entropy recognizing unit 352C recognizes the entropy of the attribute item using the attribute item of the keyword acquired by the search request information acquiring unit 352A, that is, the attribute information 342A2 set as the keyword as an instance variable. The recognition of entropy is recognized by searching the attribute group information 342A having the same attribute information 342A2 based on the attribute group information list table storage area 342 and reading the entropy information 342A4 of the attribute group information 342A. The recognized entropy information 342A4 is appropriately stored in the server storage unit 340 in association with the attribute information 342A2 set or inputted or the attribute item information 342A1. If the entropy recognizing means 352C cannot read the entropy information 342A4 by the search based on the attribute group information list table storage area 342, the document information 341A associated with the attribute information 342A2 set and input is the document information. It is determined that there is no attribute item information 342A1 that is not stored in the storage area 341, or whose attribute information 342A2 is an instance variable, and is associated with the attribute information 342A2 that has been set and input or the corresponding attribute item information 342A1. The server storage unit 340 stores the information as appropriate.

  The degree-of-association recognition unit 352D recognizes the degree of association between the attribute information 342A2 set and input as a keyword and another attribute item that is different from the attribute item in which the attribute information 342A2 is an instance variable. The recognition of the degree of association is performed by searching for the associated attribute set information 343A having the same attribute information 342A2 as the set attribute information 342A2 based on the related attribute set list storage area 343, and relating the related attribute set information 343A. The degree 1 information 343A3, the degree of association 2 information 343A4, and the degree of association 3 information 343A5 are recognized by reading. The recognized relevance level 1 information 343A3, relevance level 2 information 343A4, and relevance level 3 information 343A5 are associated with the set-input attribute information 342A2 and stored in the server storage unit 340 as appropriate. When the relevance level recognition unit 352D cannot read the relevance level 1 information 343A3, the relevance level 2 information 343A4, and the relevance level 3 information 343A5 by the search based on the related attribute set list storage area 343, the setting input Attribute information that is set and input to the effect that it is determined that the document information 341A associated with the attribute information 342A2 is not stored in the document information storage area 341, or that there is no attribute information 342A2 associated with the attribute information 342A2. It is associated with 342A2 and stored in the server storage means 340 as appropriate. Further, the relevance recognition means 352D calculates the value of the function using at least one of these as an argument based on the relevance 1 information 343A3, relevance 2 information 343A4, and relevance 3 information 343A5. , The degree of association between the paired attribute information 342A2 is recognized. Specifically, the degree of association is calculated by the calculation shown in the following formula 5.

(Equation 5)
f (Relevance 1 information, Relevance 2 information, Relevance 3 information)
= 1where relevance 1 information> threshold 1 AND relevance 2 information> threshold 2 AND relevance 3 information> threshold 3
0 otherwise

  When the display control unit 352E recognizes that the keyword is acquired by the search request information acquisition unit 352A, the display control unit 352E controls the terminal display unit 230 of the terminal device 200 to display information related to the attribute information 342A2 set as the keyword. In other words, the display control unit 352E uses the attribute information 342A3 set as a keyword based on the information amount of the information amount information 342A3 recognized by the information amount recognition unit 352B to be another instance variable in the attribute item that is an instance variable. The attribute information 342A2 is transmitted together with the information amount information 342A3 to the server communication means 310 and transmitted to the terminal device 200. This processing is received by the terminal device 200, so that the output control means 254 controls the terminal display means 230, and the attribute information 342A2 set as a keyword together with other attribute information 342A2 is listed in the order of the amount of information. In a state of display, processing for creating list display data based on a predetermined form stored in advance in the server storage unit 340 is performed. In this list display state, the attribute information 342A2 set as a keyword is displayed in a state different from the other attribute information 342A2, for example, visible from other attribute information 342A2, such as bold, flushing, color-coded display, icon attachment, etc. It is preferable to be in a state of being displayed in a highly displayable form. Further, the value of the information amount may be displayed together. Thus, the user can easily determine the standard of the number of document information 341A detected by the attribute information 342A2 set as the keyword.

  Further, the display control means 352E obtains attribute item information 342A1 of another attribute item different from the attribute item for which the attribute information 342A2 is an instance variable as information related to the attribute information 342A2 set as a keyword together with the entropy information 342A4. Processing for controlling the communication means 310 and transmitting to the terminal device 200 is performed. In this process, when the terminal device 200 receives, the output control unit 254 controls the terminal display unit 230, and the attribute items of the attribute information 342A2 set as keywords together with other attribute items in the order of entropy. In a state of displaying a list, processing for creating list display data based on a predetermined form is performed. The attribute information 342A2 is hierarchically arranged in the order of the amount of information among the attribute items displayed in a list in the order of the size of entropy by transmitting together with the data for list display corresponding to the information amount information 342A3 described above. It is possible to switch to a state displayed as a separate table instead of a hierarchy. Further, when the attribute item information 342A1 is selected by the input operation of the terminal input unit 220 in the attribute item list display state, the attribute information 342A2 serving as an instance variable is processed to be displayed as a list in the attribute item. Furthermore, the attribute information 342A2 displayed as a list is processed in a state in which the attribute information is displayed in an order corresponding to the amount of information. In a state where the attribute items are displayed in a list, the display is performed in a display form in which the visibility of the attribute items of the attribute information 342A2 set as keywords is higher than other attribute items, as in the case of the attribute information 342A2 list display. It is preferable to be in a state to be performed. Furthermore, the entropy value may be displayed together.

  Further, the display control means 352E relates to the attribute information 342A2 that is set and input as the information related to the attribute information 342A2 that is set and input as a keyword in another attribute item that is different from the attribute item that is the instance variable. The other attribute information 342A2 is transmitted to the terminal device 200 together with the relevance level information related to the relevance level calculated based on the relevance level 1 information, the relevance level 2 information, and the relevance level 3 information by the relevance level recognition unit 352D. This processing is received by the terminal device 200, so that the output control unit 254 controls the terminal display unit 230, and the other attribute information 342A2 related to the set and inputted attribute information 342A2 is used as the degree of association of the association degree information. Processing for creating list display data based on a predetermined form is performed in a state where the list is displayed in the order of the size of the values. Similarly, in the state where the list is displayed, the value of the degree of association may be displayed together. When the value of the degree of association is “0”, that is, when there is no attribute information 342A2 having a predetermined relationship, a process of creating and transmitting the information based on a predetermined form for displaying the fact is performed.

  Further, the display control unit 352E sets, based on the history information storage area 344, when the document search is performed in the past using the attribute information 342A2 as the information related to the attribute information 342A2 set and input as a keyword. The other attribute information 342A2 set and input as a keyword together with the input attribute information 342A2 is transmitted to the terminal device 200 together with the information amount information 342A3. When this processing is received by the terminal device 200, the output control means 254 controls the terminal display means 230, and the attribute information 342A2 set and inputted is displayed as a list of other attribute information 342A2 related as a history. A process for creating data for listing based on a predetermined form is performed. In this list display, for example, by performing an input operation using the terminal input unit 220, a list is displayed in the order of combinations with the highest frequency during document search, or a list is displayed in order of the information amount of the information amount information 342A3. It may be switchable. Thus, more information regarding the attribute information 342A2 can be provided.

  The display control means 352E, for example, displays a list display of attribute information 342A2 corresponding to these information amounts, a list display of attribute items corresponding to entropy, and a list display of other attribute information 342A2 corresponding to the degree of association, for example. The display screen is controlled so as to be switched and displayed by an input operation by the terminal input means 220.

  In addition to the attribute information 342A2 set and input as a keyword, the display control unit 352E causes the terminal display unit 230 to display a display prompting the user to set other attribute information 342A2 serving as a keyword for searching for documents. Take control. In addition to the transmission of the attribute information 342A2 and the attribute item information 342A1 described above, this control causes the information displayed on the terminal display unit 230 to be transmitted when the output control unit 254 of the terminal device 200 recognizes. As a display for prompting the user to set other attribute information 342A2 as a keyword for searching for a document, for example, an input operation for selecting attribute information 342A2 to be displayed in a list or a text input by an input operation by a terminal input unit For example, a text box that can be input is displayed together. Then, when other attribute information 342A2 is set and input as an additional keyword in the terminal device 200, the search request information acquisition unit 352A acquires other attribute information 342A2 as a keyword together with the attribute information 342A2 that has been previously set and input.

  The search control unit 352F performs processing for causing the search unit 353 to search for document information 341A associated with the attribute information 352A2 set and input as a keyword. That is, the search control unit 352F includes the attribute information 352A2 acquired as a keyword by the search request information acquisition unit 352A, and the other attribute information 352A2 that is displayed as a list by the display control unit 352E and set and input as an additional keyword. The search request information is output to the search unit 353, and the search unit 353 is caused to search the document information 341A associated with the attribute information 352A2 as the bibliographic information.

  The search unit 353 searches the document information 341A based on a search command from the search control unit 352F of the document information 341A associated with the attribute information 352A2 set as the keyword. In this search, document information 341A associated with attribute information 352A2, which is a keyword output from the search control means 352F, is read from the document information storage area 341, and identification information 341A2 of the document information 341A is detected. Then, the search unit 353 outputs the identification information 341A2 of the detected document information 341A and information regarding the detected number to the document display control unit 354. Note that when the number detected is greater than a predetermined number, for example, more than a preset number or an upper limit number preset as a search condition, the search unit 353 also outputs a signal to that effect. Further, when the document information 341 </ b> A cannot be detected, the search unit 353 outputs a signal to that effect to the document display control unit 354.

  The document display control unit 354 appropriately processes the document information 341A detected by the search unit 353 to notify the terminal device 200, and generates search result information. That is, the search unit 353 can list the identification information 341A2 on the terminal display unit 230 so that it can be selected by an input operation on the terminal input unit 220 of the terminal device 200 based on, for example, a predetermined form stored in advance in the server storage unit 340. Generate search result information to be displayed. At the time of this list display, it is preferable that the number of detected document information 341A is also displayed. Further, the search result information is detected together with information amount information 342A3, entropy information 342A4 and relevance level 1 information 343A3, relevance level 2 information 343A4, and relevance level 3 information 343A5 of the attribute information 342A2 set and inputted as a keyword at the time of search. It is generated including the information amount information 342A3 of the attribute information 342A2 associated with the document information 341A. Note that the information amount information 342A3 of the attribute information 342A2 associated with the detected document information 341A is recognized by the information amount recognition unit 352B as described above. When the document display control unit 354 recognizes a signal indicating that the number of document information 341A is equal to or greater than a predetermined number, the list display of attribute information 342A2 corresponding to the information amount described above and the list display of attribute items corresponding to entropy are displayed. And a screen display of information related to the attribute information 342A2 displayed in the processing by the display control means 352E, such as a list display of other attribute information 342A2 corresponding to the degree of association, and further setting input of other attribute information 342A2 The search result information is generated in a switchable state on the screen display. When the document display control unit 354 recognizes a signal indicating that the document information 341A cannot be detected, the document display control unit 354 generates search result information of a predetermined form that can be displayed on the terminal display unit 230 of the terminal device 200. .

  The document display control unit 354 stores the generated search result information as appropriate in the server storage unit 340 and controls the server communication unit 310 to transmit the search result information to the terminal device 200 via the network 110. When the terminal apparatus 200 receives the search result information to be transmitted, the output control means 254 controls the terminal display means 230, and the identification information 341A2 of the document information 341A is set as the keyword information of the attribute information 342A2. The size of the quantity information 342A3, the size of the entropy information 342A4 of the attribute item corresponding to the attribute information 342A2, the size of the relevance 1 information 343A3, the relevance 2 information 343A4, the relevance 3 information 343A5, and the degree of relevance A list is displayed corresponding to the magnitude of the value as appropriate. Note that the search result information is processed so that the state of the list display can be switched as appropriate. That is, the condition under which the document information 341A is searched can be easily determined.

  Further, the document display control means 354 displays a signal indicating that a list is displayed on the terminal display means 230 of the terminal device 200 and predetermined identification information 341A2 is selected by an input operation on the terminal input means 220, and that browsing of the text information 341A1 is requested. When recognized via the network 110, the search means 353 searches the document information storage area 341 for text information 341A1 of the document information 341A associated with the identification information 341A2. Then, the document display control unit 354 processes the text information 341A1 detected by the search unit 353 so as to be displayed on the terminal display unit 230, and transmits it to the terminal device 200 via the network 110 by the server communication unit 310. The document display control unit 354 recognizes that the number of document information 341A desired by the user has been detected by recognizing the browsing request for the text information 341A1, and notifies the history information generation unit 351D of the table generation unit 351 to that effect. The generation request signal is output. When the history information generation unit 351D recognizes the generation request signal, the history information is generated or updated based on the user specific information included in the search request information as described above.

  The billing calculating means 355 pays the consideration for notifying the search result to the user who made the search request based on the search request information or the search result information searched by the search means 353 and transmitted by the document display control means 354. Calculate. The calculation of the price corresponds to, for example, the time when the terminal device 200 is connected to the server device 300 via the network 110, the search fee for executing the search, and the information amount of the document information 341A requested to be browsed by the search result. It is calculated based on the answer output fee. The amount of consideration is transmitted together with the search result information so as to be confirmed by the terminal device 200 by the document display control means 354.

  The settlement unit 356 performs a process for collecting the consideration calculated by the charging calculation unit 355. For example, an invoice is issued based on user-specific information for specifying a user who uses a document search using the terminal device 200 stored in advance in the server storage unit 340, Settlement processing using farm banking (Firm Banking: FB) built in so-called financial VAN, which is a value-added network (VAN) managed by a financial institution, or a server display that indicates settlement processing The information is displayed on the means 330 and the administrator is notified of guidance for prompting the settlement process.

[Operation of Bibliographic Information Retrieval System]
Next, various operations in the above-described document information search system 100 will be described with reference to the drawings. FIG. 7 is a flowchart showing a processing operation for generating the attribute group information list table and the related attribute group list table. FIG. 8 is a flowchart showing a process for recognizing information related to attribute information, which is a part of an operation of a search process for searching for document information. FIG. 9 is a flowchart showing a document search process that is a part of an operation of a search process for searching for document information. FIG. 10 is a flowchart showing a process for acquiring text information based on a search result that is a part of an operation of a search process for searching for document information.

(Table generation process)
First, the processing operation for generating the attribute group information list table and the related attribute group list table in the table generation processing operation for constructing the server storage unit 340 of the server device 300 for document search will be described with reference to FIG.

  When the administrator of the document information search system 100 performs an input operation to register the document information 341A, that is, to store the document information 341A in the document information storage area 341, by the server input unit 320, the server processing unit 350 recognizes the table generation request. The means 351A recognizes a generation request signal indicating that it is a process request for generating various tables (step S101). By recognizing the generation request signal in step S101, the table generation request recognition unit 351A performs a process of causing the server display unit 330 to display a display screen for setting and inputting various setting items for table generation (step S102). .

  Then, when the administrator inputs the setting item according to the display screen, that is, when the attribute item which is the bibliographic information associated with the document information 341A to be registered and the attribute set in the attribute item are input, the attribute group information generating unit 351B The attribute item information 342A1 is generated from the input attribute item, the attribute information 342A2 is generated from the input attribute, and the attribute item information 342A1 and the attribute information 342A2 are associated as a pair, for example, in the attribute group information list table storage area 342 Store (step S103). Then, the attribute set information generation unit 351B recognizes that the registration of the pair of the attribute item information 342A1 and the attribute information 342A2 in the bibliographic information of all the document information 341A to be registered is completed by an input operation by the server input unit 320, for example. Then, the information amount calculation means 351B1 calculates the information amount of the attribute information 342A2 in each pair (step S104). The calculation of the information amount in step S104 calculates the attribute appearance probability for the attribute item based on Equation 1 described above, calculates the information amount in each pair based on Equation 2, and generates information amount information 342A3. The corresponding registered attribute item information 342A1 and attribute information 342A2 are registered in association with one data structure.

  Further, after the calculation of the information amount in step S104, the entropy calculation means 351B2 calculates the sum of the information amounts corresponding to the attribute information 342A2 serving as the instance variable for each attribute item to calculate the entropy of each attribute item. The entropy information 342A4 is generated (step S105). Then, the generated entropy information 342A4 is associated with the corresponding registered attribute item information 342A1, and attribute group information 342A is generated (step S106), and stored in the attribute group information list table storage area 342 (step S107).

  After this step S107, the degree-of-association information generation unit 351C uses the attribute group information list table storage area 342, and based on the information amount information 342A3, the degree of association described above in each combination of attribute information 342A2 in different attribute items, MI (Ai = Vj; Ak = Vl) is calculated, and the degree of relevance 1 information 343A3 is greater than a predetermined threshold (step S108). And it associates with the pair of attribute information 342A2 of the combination corresponding to the relevance 1 information 343A3. That is, the attribute information 342A2 of one attribute item is set as the attribute set 1 information 343A1, and the attribute information 342A2 of the other attribute item is set as the attribute set 2 information 343A2 to be constructed in one data structure. Furthermore, the value of p (Ak = Vl ^ Ai = Vj) calculated when calculating the relevance degree MI (Ai = Vj; Ak = Vl) to the predetermined pair of attribute group 1 information 343A1 and attribute group 2 information 343A2 2 The value of the information 343A4 and p (Ak = Vl | Ai = Vj) is set as the relevance level 3 information 343A5, and the related attribute set information 343A is generated in association with one data structure (step S109), and the related attribute set list storage area 343 (step S110), and the table generation process ends.

(Document search processing)
Next, an operation of a search process for searching for predetermined document information 341A in the document information search system 100 will be described with reference to FIGS.

  When searching for a document using the document information search system 100, first, a user appropriately inputs and operates the terminal input unit 220 of the terminal device 200 so that various types of information can be transmitted and received via the server device 300 and the network 110. The device 200 is connected. As this connection, for example, access to a homepage or the like in which the server device 300 that is built by installing application software for the server device in advance is resident can be exemplified. Then, the user appropriately inputs the terminal input unit 220 according to the screen display displayed on the terminal display unit 230, and inputs the bibliographic information associated with the document as a keyword for searching the document. By this input operation, the keyword setting unit 251 of the terminal processing unit 250 sets the attribute information 342A2, which is bibliographic information input from the terminal input unit 220, as a keyword (step S201).

  Thereafter, the terminal processing unit 250 appropriately operates the terminal input unit 220 according to the screen display, and determines whether or not a document search request has been input (step S202). The presence or absence of a document search request in step S202 can be exemplified by, for example, an input operation of a command button provided on the display screen of the terminal display unit 230 and prompting execution of search or command button prompting execution of information presentation. In step S202, if there is no document search request, the terminal processing unit 250 determines that the request setting unit 252 requests to present information related to the attribute information 342A2 set as a keyword. Information presentation request information to that effect is generated (step S203). On the other hand, if there is a document search request in step S202, the terminal processing unit requests the search of the document information 341A in which the attribute information 342A2 set as the keyword is associated as the bibliographic information by the request setting unit 252. And the search request information to that effect is generated (step S204). Then, after setting the request information by the request setting unit 252 in step S203 and step S204, the terminal processing unit 250 performs a process of causing the terminal communication unit 210 to transmit the request information to the server apparatus 300 via the network 110 (step). S205).

  Then, when the server device 300 receives the search request information and the information presentation request information transmitted from the terminal device 200 in step S205 (step S206), the search request information acquisition unit 352A of the server processing unit 350 receives the search request information acquisition unit 352A. The attribute information 342A2 set as a keyword included in the search request information and the information presentation request information is acquired (step S207). Based on the attribute information 342A2 acquired in step S207, the server processing unit 350 performs an information recognition process for recognizing information related to the attribute information 342A2.

  That is, the amount of information related to the set attribute information 342A2, the entropy of the attribute item for which the attribute information 342A2 is an instance variable, the other attribute information 342A2 related to the attribute information 342A2, and the degree of association thereof, Recognition is performed based on the attribute group information 342A and the related attribute group information 343A in the storage unit 340 (step S208). Specifically, the information amount recognition unit 352B of the server processing unit 350 searches for attribute group information 342A having the same attribute information 342A2 as the attribute information 342A2 set and input, and recognizes the information amount from the attribute group information 342A. The information amount information 342A3 is read by the means 352B, and the entropy information 342A4 is read by the entropy recognition means 352C. Further, the server processing unit 350 uses the association level recognition unit 352D to set the attribute set 1 information 343A1 or the attribute set in which the same attribute information 342A2 as the set attribute information 342A2 is set based on the related attribute set list storage area 343. The related attribute group information 343A having the group 2 information 343A2 is searched, and the attribute information 2342 or the attribute group 1 information in which the other attribute information 342A2 which is the other of the set attribute information 342A2 is set, and the relevance degree 1 information 343A3, relevance level 2 information 343A4, and relevance level 3 information 343A5 are read. Then, as the degree of association of each attribute information 342A2, the degree-of-association recognition unit 352D calculates the degree of association of the other attribute information 342A2 related to the set and inputted attribute information 342A2 based on the above formula 5.

  After this step S208, the server processing unit 350 causes the display control unit 352E to display a list of attribute information 342A2 based on the amount of information and to display a list of attribute items based on entropy. Data and list display data for notifying attribute information 342A2 of other attribute items related to the attribute information 342A2 set and input in a list display are created (step S209). Further, the server processing unit 350 executes the process of presenting information related to the attribute information 342A2 set and input as a keyword by the charging calculation unit 355, for example, the time when the terminal device 200 is connected to the server device 300 via the network 110. Based on the information provision fee for the user, a consideration related to information provision is calculated for the user (step S210). Thereafter, the server processing unit 350 performs processing for transmitting the list display data created by the display control unit 352E together with information related to information provision to the terminal device 200 via the network 110 by the server communication unit 310. (Step S211).

  When the terminal communication unit 210 receives the data for list display and the information providing consideration transmitted in step S211 by the terminal communication unit 210 (step S212), the output control unit 254 of the terminal processing unit 250 uses the terminal display unit. 230 is appropriately controlled so that a list display of attribute information 342A2 corresponding to the amount of information, a list display of attribute items corresponding to entropy, and a list display of other attribute information 342A2 corresponding to the degree of association can be switched and displayed. A screen is displayed together with the amount (step S213). Then, the terminal processing unit 250 sets other attribute information 342A2 as an additional keyword based on a display prompting the user to set other attribute information 342A2 as a keyword for searching for documents on the screen display. It is determined whether or not (step S214). Examples of the setting input for the additional keyword include an input operation for selecting the attribute information 342A2 displayed in a list and a text input in a setting text box.

  If it is determined in step S214 that no additional keyword has been set and input, it is determined whether a search request has already been made to the server apparatus 300 (step S215). For example, it is determined whether or not the request information transmitted in step S205 is search request information. If it is determined in step S215 that a search request has already been made, the terminal processing means 250 sets a search command for executing a search for the document information 341A based on the search request information already transmitted (step S216). Then, the terminal communication unit 210 performs a process of transmitting to the server apparatus 300 via the network 110 (step S217). On the other hand, if it is determined in step S215 that the search is not requested, that is, only the presentation of information related to the attribute information 342A2 is requested, the terminal processing unit 250 uses the request setting unit 252 to set the attribute information 342A2 that has already been set as a keyword. Search request information for requesting a search for the document information 341A associated with the bibliographic information is generated (step S218). Thereafter, the process proceeds to step S217, and the terminal processing unit 250 transmits the generated search request information to the server device 300.

  On the other hand, when determining that an additional keyword is set and input in step S214, the terminal processing unit 250 sets the attribute information 342A2 set and input as an additional keyword by the keyword setting unit 251 (step S219). Furthermore, the terminal processing unit 250 determines whether a search request has already been made to the server device 300 (step S220). If it is determined in step S220 that a search request has already been made, the terminal processing unit 250 associates a plurality of pieces of attribute information 342A2 set as keywords and additional keywords in the already transmitted search request information as bibliographic information. A search command is set to cause the document information 341A to be searched under conditions based on the search request information that has already been transmitted (step S221). Thereafter, the process proceeds to step S217, and the terminal processing unit 250 transmits the generated search command to the server apparatus 300. On the other hand, if it is determined in step S220 that the search is not requested, that is, only the presentation of information related to the attribute information 342A2 is requested, the terminal processing unit 250 uses the request setting unit 252 to set the attribute information 342A2 already set as a keyword. At the same time, search request information for requesting a search for the literature information 341A in which the attribute information 342A2 set as the additional keyword is associated as the bibliographic information is generated (step S222). Thereafter, the process proceeds to step S217, and the terminal processing unit 250 transmits the generated search request information to the server device 300.

  When the server apparatus 300 receives the search command or the search request transmitted in step S217 by the server communication unit 310 (step S223), based on the search request information acquired by the search request information acquisition unit 352A of the server processing unit 350, The search control unit 352F controls to search the document information 341A in the search unit 353 (step S224). After the search process by the search unit 353, the server processing unit 350 generates search result information based on a predetermined form by the document display control unit 354. In addition, the server processing unit 350 performs processing for generating history information by recognizing the user-specific information that is the subject of the search request based on the search request information by the history information generation unit 351D (step S225). In the history information generation process, when history information having the same user-specific information has already been stored, the number of times of search in the number information of the history information is added by one. Furthermore, the attribute information 342A2 set as a keyword at the time of search is associated with the user-specific information, or if attribute information 342A2 having the same combination as the keyword at the time of search exists, a process such as adding once is performed. Update history information. If history information is not stored, new history information is generated and stored in the history information storage area 344. Further, the server processing unit 350 uses the accounting calculation unit 355 to answer, for example, the time when the terminal device 200 is connected to the server device 300 via the network 110, the search fee for executing the search, and the information amount of the search result. Based on the output fee or the like, a consideration related to notification of the search result is calculated for the user who has requested the search (step S226). Then, the server processing unit 350 performs processing for transmitting the search result information created by the document display control unit 354 together with information related to the search price to the terminal device 200 via the network 110 by the server communication unit 310 (step S227). ).

  When the terminal communication unit 210 receives the search result information and information related to the search price transmitted in step S227 (step S228), the terminal display unit 230 is appropriately set by the output control unit 254 of the terminal processing unit 250. Control is performed to display a list of identification information 341A2 that can be selected by an input operation at the terminal input means 220 (step S229). When this list is displayed, a list is displayed corresponding to the information related to the attribute information 342A2 set as a keyword. For example, based on the information related to the attribute information 342A2 received from the server device in step S212, a list is displayed in an order corresponding to the magnitude of the information amount, the magnitude of the entropy, and the magnitude of the degree of relevance.

  Thereafter, the terminal processing unit 250 determines whether or not a browsing request for the text information 341A1 of the document information 341A is input (step S230). For example, it is determined whether or not the identification information 341A2 such as the publication number of the document information 341A displayed in a list is selected by the input operation by the terminal input unit 220. When recognizing that there is no text browsing request in step S230, the terminal processing means 250 determines whether or not an information presentation request process or a document search process end request regarding the attribute information 342A2 has been input (step S231). ). If it is determined in step S231 that an end request has not been input, the process proceeds to step S230. On the other hand, if it is determined in step S231 that an end request has been input, the process ends.

  On the other hand, when recognizing that there is a body text browsing request in step S230, the terminal processing unit 250 requests the server device 300 to distribute the requested body information 341A1 including the identification information 341A2 requested by the request setting unit 252. Setting is performed (step S232), and processing for transmission to the server device 300 is performed (step S233).

  When the server apparatus 300 receives the distribution request for the text transmitted in step S233 by the server communication unit 310 (step S234), the server processing unit 350 uses the search unit 353 to search for the text information of the document information 341A associated with the identification information 341A2. 341A1 is retrieved from the literature information storage area 341. Then, the document display control means 354 processes the text information 341A1 detected by the search means 353 based on a predetermined form so that it can be browsed by the terminal display means 230 (step S235). Further, the server processing unit 350 uses the accounting calculation unit 355 to answer, for example, the time when the terminal device 200 is connected to the server device 300 via the network 110, the search fee for executing the search, and the information amount of the search result. Based on the output fee or the like, a consideration relating to the notification of the text search result is calculated for the user (step S236). Then, the server processing unit 350 performs processing for transmitting the text information 341A1 processed by the document display control unit 354 to be displayed together with information related to the text search value to the terminal device 200 via the network 110 by the server communication unit 310. (Step S237).

  When the terminal device 200 receives the text information 341A1 and the information related to the text search price transmitted in step S237 by the terminal communication means 210 (step S238), the output control means 254 of the terminal processing means 250 causes the terminal display means 230 to be changed. The text information 341A1 is displayed together with the amount of consideration by appropriately controlling (step S239), and the process proceeds to step S231.

  On the other hand, in the server apparatus 300, after transmitting the text information 341A1 and the information related to the text search in step S237, the settlement means 356 performs processing for collecting the price calculated by the billing calculation means 355. For example, the user is identified from the user-specific information of the search request information and the information presentation request information stored in advance in the server storage unit 340, and an invoice is issued based on the customer information or so-called via the network 110 Processing such as settlement processing using farm banking built in the financial VAN, or displaying notification that settlement processing is to be performed on the server display means 330 and notifying the administrator of guidance for settlement processing (step S240) Then, the processing in the server device 300 ends.

[Effects of Embodiment]
As described above, in the above embodiment, all the attribute items in all the document information 341A stored in the document information storage area 341 of the server storage unit 340 as search targets and the attributes in which attributes are set for these attribute items, respectively. Information amount information related to the information amount obtained by multiplying the logarithm of the appearance probability for each attribute item 342A2 for each attribute item by -1 for the combination of information 342A2 stored in the attribute group information list table storage unit 342 of the server storage unit 340 342A3 is recognized by the information amount recognition means 352B. Then, the display control unit 352E causes the terminal display unit 230 to display a list of attribute information 342A2 that is an instance variable for each attribute item as a keyword for searching the document information 341A in the order corresponding to the amount of information. I have control. For this reason, the attribute information 342A2 that can be set and input as a keyword for document search is displayed in a list in a state that significantly corresponds to the value of the appearance probability in the attribute item, and the user can use the attribute information for document search. If any attribute information 342A2 is set and inputted as 342A2, it can be easily determined whether the document information 341A can be detected in an appropriate number. Accordingly, it is possible to reduce the number of search conditions to be set and the number of searches to be performed so that the user can search for an appropriate number of document information 341A desired by the user, the load of the setting input operation by the user can be reduced, and the user can search for documents well. Can provide good support. As a result, the use can be easily expanded.

  Furthermore, the entropy information relating to the entropy of the attribute item obtained by adding the information amount of the information amount information 342A3 of each attribute information 342A2 for each attribute item is stored by the entropy recognition unit 352C in the attribute group information list table storage unit 342 of the server storage unit 340. 342A4 is recognized. The display control unit 352E controls the terminal display unit 230 to display a list of the attribute item information 342A1 in the order corresponding to the recognized entropy size. Therefore, the attribute information 342A2 that can be set and input as a keyword for document search is displayed in a list even in a state corresponding to the appearance probability in the attribute item, and the attribute information 342A2 for detecting the desired document information 341A in an appropriate number is displayed. Users can judge more easily. Further, the display control unit 352E controls the superiority of the attribute items corresponding to the entropy size, that is, the terminal display unit 230 displays a list of the attribute information 342A2 in order. Therefore, the user can more easily determine the attribute information 342A2 for detecting the desired document information 341A with a more appropriate number.

  In addition, when an attribute item displayed in a list corresponding to the size of entropy is selected, attribute information 342A2 serving as an instance variable can be displayed as a list in the attribute item. For this reason, it is possible to easily select attribute information 342A2 to be set as a keyword for detecting a proper number of document information 341A desired by the user by a simple operation, and for a better search. Can provide support.

  Further, when the attribute information 342A2 set and input as a keyword acquired by the search request information acquisition unit 352A is recognized for presentation of information related to the attribute information 342A2 for document search, the information amount information is received by the relevance recognition unit 352D. Based on 342A3, relevance information on the degree of relevance in a combination of other attribute information 342A2 that becomes an instance variable with an attribute item different from the attribute item of the input attribute information 342A2 and the input attribute information 342A2 recognize. Then, the display control means 352E causes the attribute information 342A2 in the other attribute items to become other keywords for searching for documents related to the attribute information 342A2 set and input in the order corresponding to the magnitude of the degree of association. A list is displayed on the terminal display unit 230 as the attribute information 342A2. Therefore, it is possible to easily select other attribute information 342A2 to be set and input as an additional keyword for narrowing down the document information 341A desired by the user in an appropriate number, and to select the desired document information in a more appropriate number. The user can more easily determine the attribute information 342A2 for detecting 341A, and can provide good support that allows the user to search for documents well.

  In addition, as the degree of relevance based on the amount of information, calculation based on Equation 4 described above, relevance 1 information 343A3, relevance 2 information 343A4 and relevance 3 information 343A5 are calculated, and based on these, the relevance is recognized. Yes. For this reason, the relevance between the different attribute items of the attribute information 342A2 associated with the document information 341A can be appropriately obtained by a simple calculation, and a good search result desired by the user can be easily obtained.

  Further, based on the calculated relevance level 1 information 343A3, relevance level 2 information 343A4, and relevance level 3 information 343A5, the relevance level of the attribute information 342A2 between the different attribute items is calculated based on the above-described formula 5. . For this reason, the relevance between different attribute items of the attribute information 342A2 associated with the document information 341A can be more appropriately obtained by a simple calculation, and a good search result desired by the user can be easily obtained. Furthermore, as shown in Equation 5, when the magnitude of the argument is determined based on a predetermined threshold value and a predetermined related state cannot be obtained, the related degree is set to “0” and there is no relevance. For this reason, since the combination of the attribute information 342A2 having low relevance is excluded, a document search with a more appropriate number can be easily obtained.

  Then, an attribute group information list table storage area 342 for storing attribute group information 342A in which the information amount information 342A3 obtained by calculating the information amount in advance is associated with the corresponding attribute information 342A2 is constructed, and this attribute group information list table The information amount recognition unit 352B reads and recognizes the information amount information 342A3 from the storage area 342. For this reason, it is not necessary to calculate the amount of information every time information on the attribute information 342A2 is notified for supporting document search, and the processing speed can be easily increased. Furthermore, as the relevance level, a relevance attribute group in which relevance level 1 information 343A3, relevance level 2 information 343A4, and relevance level 3 information 343A5, which are arguments calculated in advance by Equation 4, are associated with combinations of attribute information 342A2 in different attribute items. The related attribute set list storage area 343 for storing the information 343A is constructed, and based on the related degree 1 information 343A3, the related degree 2 information 343A4, and the related degree 3 information 343A5 in the related attribute set information 343A of the related attribute set list storage area 343. This is calculated by Equation 5. For this reason, the relevance can be calculated at a relatively high speed, and the processing efficiency can be easily improved.

  Further, the server processing unit 350 is provided with table generation means 351 for generating an attribute group information list table and a related attribute group list table used for presenting various information related to the attribute information 342A2. For this reason, even in a configuration in which a plurality of document information 341A associated with a plurality of attribute information 342A2 is a search target, table generation for presentation of various types of information can be facilitated, and system construction can be facilitated.

  In addition, the attribute information 342A2 displayed in a list can be selected as other attribute information 342A2 for document search by an input operation in the terminal input unit 220. For this reason, it becomes easy to set other attribute information 342A2 for narrowing down to detect an appropriate number of document information 341A desired by the user as an additional keyword, and provide support for better search. it can.

  The search control unit 352F that has recognized the search request controls the search unit 353 to perform a document search. For this reason, the present invention can be applied not only to searching for documents but also to displaying the attribute information 342A2 in a list so that the user can recognize various information related to the attribute information 342A2, thereby improving versatility.

  In addition, as a list display of the detected document information 341A, identification information 341A2 such as a publication number is displayed as a list. For this reason, only the necessary text information 341A1 having a relatively large amount of information needs to be acquired separately, the load of transmission and display processing for displaying the search result is reduced, and the speed can be easily increased. Can be simplified, and the user can easily recognize the detection state.

  Furthermore, when displaying various information related to the attribute information 342A2 and displaying a list of the detected document information 341A, values such as information amount, entropy, and degree of association that cause ordering are also displayed. For this reason, it becomes easier to determine the state and selection of information related to the attribute information 342A2, and the detection conditions of documents, and the like, and better support can be provided.

  In addition, a system configuration is adopted in which the server apparatus 300 appropriately processes according to a request from the terminal apparatus 200 connected via the network 110 to present information on the attribute information 342A2 and report a document search result. For this reason, even with the simple configuration of the terminal device 200, the state of the attribute information 342A2 and the literature search can be easily performed, and the use can be easily expanded. Furthermore, the server apparatus 300 can manage the document information 341A and the bibliographic information with a large capacity in an integrated manner, and data can be easily updated, so that the operational manageability can be easily improved. Therefore, even if a mobile phone or the like having a relatively small processing capability is used, a search can be easily performed and the use can be easily expanded.

  And it is comprised so that the presentation process and search process of the information regarding attribute information 342A2 can be performed as a program in a personal computer or the like. For this reason, by using a recording medium in which the program is incorporated or the program is recorded, the above processing can be easily obtained, and the use can be easily expanded.

[Modification of Embodiment]
Note that the present invention is not limited to the above-described embodiment, and includes the following modifications as long as the object of the present invention can be achieved.

  For example, although the system configuration has been described, a single personal computer is used to appropriately search the document information 341A from the recording medium that is the document information storage area 341, or the document information storage area 341 is connected via the network 110. The server device 300 is configured to perform a document search process based on control from the terminal device 200 as a configuration in which the terminal device 200 is provided with the search support unit 352, or the table generation unit 351 and the search support unit 352. The server storage unit 340 may be separated from the server device 300 and configured as a separate server device via the network 110. .

  Then, when the keyword is set, the other attribute information 342A2 is displayed as a list based on the size of the information amount and the size of the entropy. However, the present invention is not limited to this. For example, the number of document information 341A associated with the keyword acquired by the search request information acquisition unit 352A as attribute information 342A by the display control unit 352E and the number of document information 341A associated with other attribute information 342A2 in the attribute item. May be recognized and displayed in a list in the order of the size. In this case, information regarding the number counted in advance may be stored in association with the attribute group information 342A and read from the attribute group information list table storage area 342. Even in this case, the counted numbers may be displayed together as a list. Even in the configuration in which the attribute information 342A2 is displayed as a list based on the size of the number of the related document information 341A, the same effects as the above-described embodiment can be obtained. Further, since it is based on the number of related literature information 341A, the amount of information stored in the arithmetic processing and attribute group information list table storage area 342 can be reduced, and the processing speed and configuration can be simplified easily.

  In addition, the display control means 352E appropriately performed the description display of the attribute information 342A2 corresponding to the information amount, the attribute item corresponding to entropy, and the other attribute information 342A2 corresponding to the degree of association. However, these screen displays may be displayed by changing the display area by scrolling, switching display by selection, or displaying in any display form. Further, only one of these displays or a combination thereof may be displayed. It should be noted that only the screen display that displays the attribute information 342A2 in the other attribute items in the order corresponding to the set input keyword and corresponding to the magnitude of the degree of relevance is displayed, so that the user or bibliography who is unfamiliar with the input operation Even a user who is not very knowledgeable of information can easily recognize the attribute information 342A2 to be set for narrowing down.

  Furthermore, the display control means 352E is not limited to a configuration that displays a list of related combinations of the attribute information 342A2 based on the relevance level 1 information 343A, the relevance level 2 information 343A4, and the relevance level 3 information 343A5, but at least any one of them. A list may be displayed based on only.

  Further, the control for displaying a list on the terminal display unit 230 has been described. However, the display is not limited to the display. For example, the output can be performed by a printing device (not shown) connected to the terminal device 200 by an input operation by the terminal input unit 220. Or audio output may be possible.

  Further, the data structure having the attribute item information 342A, the attribute information 342A2, the information amount information 342A3, and the entropy information 342A4 has been described as the attribute group information 342A. For example, the entropy information 342A4 is constructed as a separate table associated with the attribute item information 342A1. For example, the information information 342A3 corresponding to the attribute information 342A2 can be read.

  In addition, an attribute group information list table and a related attribute group list table are constructed in advance, and information on the attribute information 342A2 set as a keyword is presented, that is, a list of attribute information 342A2 corresponding to the information amount, an attribute item corresponding to entropy In the above description, the list display of other attribute information 342A2 corresponding to the degree of association is performed, and the like. However, the amount of information, entropy, and degree of association may be calculated each time information related to the attribute information 342A2 is presented. . That is, the information amount calculation unit 351B1 of the table generation unit 351 and the information amount recognition unit 352B of the search support unit 352 are configured as one configuration, and the entropy calculation unit 351B2 and the entropy recognition unit 352C are configured as a single configuration, and the relevance information generation The means 351C and the relevance level recognition means 352D may be configured as one. According to such a configuration, the configuration for storing the attribute group information list table storage area 342 and the related attribute group list storage region 343 is unnecessary, the capacity of the server storage unit 340 can be effectively used, and the configuration can be simplified. It is done.

  Then, the relevance degree of the attribute information 342A2 in the different attribute items is calculated and recognized based on the equations 4 and 5, but the relevance information regarding the calculated relevance degree is associated with the related attribute group information 343A in advance in the server storage. It is good also as a structure which memorize | stores in the means 340 and recognizes a related degree based on related attribute group information 343A. Furthermore, the appearance probability of the combination of the attribute information 342A2 is calculated, and the appearance probability is set as the relevance level, or any one of the relevance level 1 information 343A3, the relevance level 2 information 343A4, and the relevance level 3 information 343A5 is set as the relevance level. The degree of association may be recognized by any method, not limited to the calculations of equations 4 and 5. Further, based on the relevance level 1 information 343A3, the relevance level 2 information 343A4, and the relevance level 3 information 343A5, the relevance degree is recognized by calculation in Equation 5, but the relevance degree is recognized in advance and the related attribute set information 343A is obtained. You may associate as relevance information. According to this configuration, the processing speed can be further increased. In addition, it is good also as a ratio with respect to the total number of the literature information 341A in the number of the collections of the literature information 341A with which the combination of attribute information 342A2 was linked | related as an appearance probability of the combination of attribute information 342A2. According to this configuration, the degree of association of the attribute information 343A2 can be easily calculated.

  In addition, the list is displayed corresponding to the degree of the degree of association of the attribute information 342A2 in different attribute items, but is not limited thereto. For example, as a list display of other attribute information 342A2 related to the set and inputted attribute information 342A2, the order of the amount of information of the other attribute information 342A2 or the entropy of the attribute item of the other attribute information 342A2 The same effect can be obtained even if the list is displayed in the order corresponding to the size.

  Further, when other attribute information 342A2 is displayed as a list, any other attribute information 342A2 may be selected as an additional keyword to display a list in a display form indicating that the number of documents to be detected is reduced. Good. With this configuration, it is possible to easily make a determination for allowing a user to retrieve a document by an appropriate number. Then, the number of documents to be detected may be displayed together as a display form indicating that the number is reduced. With this configuration, it is possible to search the desired document information 341A by an appropriate number with a minimum input operation, and it is possible to provide support for better document search.

  In addition, as a list display of the detected document information 341A, identification information 341A2 such as a publication number is displayed as a list. However, the text information 341A1 may be transmitted and the text information 341A1 may be displayed as a list. That is, since it is possible to search by narrowing down to several cases, it is possible to display a list of several cases. As a result, an operation for selecting the identification information 341A2 and acquiring the text information 341A1 becomes unnecessary, and the document information 341A can be acquired satisfactorily.

  Further, the list display of the document information 341A is not limited to the configuration in which the information amount of the keyword attribute information 342A and the order of the values of the degree of association are displayed, but for example, the sum of the information amount of each attribute information 342A2 May be displayed in a list corresponding to the total amount of information.
