  By the way, in the above-described conventional technology, there is a problem that highly useful content cannot be appropriately presented. That is, even if the system presents content related to the content that the user is interested in, the related content is selected based on the history information of the user, which is not appropriate from the viewpoint of usability. There is a risk. In addition, the techniques disclosed in Patent Documents 2 to 4 cannot solve the above-described problems.

  Accordingly, the present invention has been made to solve the above-described problems of the conventional technology, and provides a content display method, a content display device, and a content display program capable of appropriately presenting highly useful content. The purpose is to provide.

  In order to solve the above-described problems and achieve the object, the disclosed content display method is based on a usage history database in which a computer stores history information of users who use content in association with the content. A selection step of selecting a content pattern in which the number of users who use all of the content included in the content pattern exceeds a predetermined number from content patterns that can be established as a combination of content included in the content set that is a set of content For each content pattern selected in the selection step, content that is used by the user at a higher usage than the predetermined usage is determined from among users who use all of the content included in the content pattern. Select users who used at a higher rate than A user selection step, be a requirement to perform a display step of displaying on the output section of the correspondence between the content utilized by the user selecting the user selected by the process and the user.

  According to the disclosed content display method, highly useful content can be appropriately presented. For example, a user can easily find hidden useful content or content that is likely to become a popular content in the future with reference to the usage patterns of powerful users.

  Exemplary embodiments of a content display method, a content display device, and a content display program according to the present invention will be described below in detail with reference to the accompanying drawings. In addition, as an example of the content display device, an “inter-content relationship display device” will be described. In the following, main terms used in the embodiment will be described first, and then the basic concept of the inter-content relationship display device in the embodiment 1 will be described. Next, an overview of the inter-content relationship display device in the first embodiment, the configuration of the inter-content relationship display device in the first embodiment, the processing procedure by the inter-content relationship display device in the first embodiment, and the effects of the first embodiment will be described in order. Finally, another embodiment will be described.

[Explanation of terms]
First, main terms used in the following examples will be described. “Content” refers to information itself. For example, in the Internet sales service, information related to a product provided to a user is “content”. For example, in an information sharing system in an organization, a material provided to a user is also “content”. As described above, the “content” is information itself that provides some content to the user.

  By the way, “content” generally forms a “content set” which is a set of a plurality of “contents”. For example, when “content” is information related to a specific product, the “content set” can be considered as a set of information related to a product including another product. Further, for example, when “content” is a proposal created for a specific customer in the organization, the “content set” can be considered as a collection of proposals including other customers. .

  If this is the case, when the user uses “content”, not only the “content” that the user is paying attention to, but also other “content” included in the “content set” It is desirable to be presented as “content” related to “content”. Of course, the related “content” is meaningless unless it is highly useful to the user. Therefore, the inter-content relationship display apparatus according to the first embodiment selects a related “content” using history information of other users.

  In the following embodiments, the related “content” is selected using the history information of the “evaluator” (corresponding to “user” described in the claims) who “evaluated” “content”. And present it to the user.

[Basic Concept of Content Relationship Display Device in Embodiment 1]
Next, the basic concept of the inter-content relationship display apparatus according to the first embodiment will be described with reference to FIGS. FIG. 1 is a diagram for explaining the basic concept of the inter-content relationship display apparatus according to the first embodiment. FIG. 2 is a diagram for explaining various databases. FIG. 3 is a diagram for explaining a specific example of processing of the inter-content relationship display apparatus. FIG. 4 is a diagram for explaining an example of obtaining an evaluation record corresponding to the designated usage mode. FIG. 5 is a diagram for explaining an example of calculating the evaluator's influential degree.

  As illustrated in FIG. 1, the inter-content relationship display apparatus according to the first embodiment includes an evaluation comment DB (DataBase), a usage pattern dictionary DB, and a content DB in a storage unit. Here, various databases will be briefly described with reference to FIG.

  The evaluation comment DB is a database that stores the history information of the evaluator who evaluated the content in association with the content. Specifically, the evaluation comment DB stores a content identifier for identifying content in association with an evaluator identifier for identifying an evaluator. As shown in FIG. 2, the evaluation comment DB in the first embodiment stores “content identifier” and “evaluator (identifier)” in association with each other and stores “evaluation comment” in association with each other. . For example, in the evaluation comment DB, “evaluator 1” evaluated the content identified by “content A.” The evaluation comment by “evaluator 1” is “Proposal of a new solution to a customer who is thinking about medical care” "It was helpful to me." Hereinafter, such association is referred to as an evaluation record. In the following description, even if the evaluator's evaluation comment is not stored in the evaluation comment DB, the evaluator treats the content as “evaluated”.

  The usage pattern dictionary DB is a database that stores keywords indicating usage patterns of content. Specifically, as shown in FIG. 2, the usage pattern dictionary DB stores a usage pattern and a keyword in association with each other. Here, the usage mode is a mode in which a user who uses content uses the content. Referring to the example of FIG. 2, for example, “examination of proposal contents” is a usage form at a stage where a user examines contents proposed to a customer. In addition, for example, “material writing” refers to a usage form at a stage where a user creates a material that expresses proposal contents. The usage pattern dictionary DB stores a keyword of the usage pattern for each such usage pattern. For example, the usage pattern dictionary DB stores ““ concept ”,“ system configuration ”,..., As keywords of“ examination of proposal contents ”.

  The content DB is a database that stores content. Specifically, as shown in FIG. 2, the content DB stores an identifier for identifying content and a content body in association with each other. The content DB may store an electronic file as a “content body”, or may store a pointer indicating a storage location of the content.

  Returning to FIG. 1, the inter-content relationship display apparatus according to the first embodiment accepts specification of a content set and a usage pattern as illustrated in FIG. 1. That is, when the user inputs the specification of the content set and the usage form, the inter-content relationship display apparatus accepts the specification.

  Next, the inter-content relationship display apparatus according to the first embodiment acquires an evaluation record set corresponding to the usage pattern designated by the user from the evaluation comment DB (S1). Subsequently, the inter-content relationship display device acquires an evaluation record corresponding to the content set designated by the user from the acquired evaluation record set (S2). That is, the inter-content relationship display apparatus according to the first embodiment narrows down the evaluation comment DB that stores the evaluator's history information based on the usage form and the content set specified by the user, and only the corresponding evaluation records. To get.

  Subsequently, the inter-content relationship display apparatus according to the first embodiment selects a representative evaluator who can express the main content relationship (S3). Here, first, the relationship between contents is a content pattern that can be established as a combination of contents included in a content set. For example, when “content A” to “content D” are included in the content set, the combination of “content A” and “content B”, the combination of “content A” and “content C”, etc. It is a relationship. In other words, it can be said that the relationship between contents is a combination of groups of contents that may be related for the time being as the same group regardless of whether or not they are highly useful to users.

  Next, the relationship between main contents is a combination of contents that are often evaluated by a common evaluator among such contents relationships. Here, the common evaluator is an evaluator who has evaluated all of “content A” and “content B” included in the combination of “content A” and “content B”. In other words, the relationship between main contents is a relationship between contents highly evaluated by a common evaluator, and it can be said that the probability that it can be regarded as a group of related contents has increased.

  The representative evaluator who can express the relationship between the main contents is a leading evaluator among the evaluators who evaluated all the contents included in the relationship between the main contents. Here, an influential evaluator is an evaluator who tends to carefully select and evaluate popular content that is highly likely to be evaluated by many evaluators.

  A method for selecting a representative evaluator who can express the relationship between main contents will be described in detail. The inter-content relationship display apparatus according to the first embodiment selects a main inter-content relationship from among the inter-content relationships that can be established as a combination of the contents included in the evaluation record acquired in S2. That is, the inter-content relationship display device selects the inter-content relationship in which the number of evaluators who have evaluated all the contents included in the inter-content relationship exceeds a predetermined number.

  Subsequently, the inter-content relationship display device selects a leading evaluator as a representative evaluator from among evaluators who evaluated all the contents included in the main content relationship for each selected main content relationship. That is, the inter-content relationship display device selects an evaluator who has evaluated popular content evaluated by an evaluator with a higher number of evaluators than a predetermined number of evaluators at a ratio higher than a predetermined ratio.

  Then, the inter-content relationship display apparatus according to the first embodiment corresponds to the correspondence between the representative evaluator selected in S3 and the designated content (content included in the content set designated by the user) evaluated by the representative evaluator. Is displayed on the output section. For example, as shown in FIG. 1, the inter-content relationship display device displays evaluators and content as nodes and displays them as a bipartite graph that expresses correspondences as edges.

  Note that the inter-content relationship display apparatus according to the first embodiment presents content by receiving an input of a selection instruction for selecting the content displayed on the output unit at the output unit (S5).

[Specific Example of Processing of Content Relationship Display Device]
Now, a specific example of the inter-content relationship display apparatus that has been described with reference to FIG. 1 will be described with reference to FIG. In FIG. 3, an edge connecting an evaluator and content represents an evaluation record.

  As shown in FIG. 3, the inter-content relationship display apparatus according to the first embodiment accepts specification of a content set and a usage form. For example, the inter-content relationship display apparatus accepts “content A”, “content B”, “content C”, and “content D” as designations of content sets. Further, the inter-content relationship display apparatus accepts “usage form X” as designation of the use form.

  Next, the inter-content relationship display apparatus according to the first embodiment acquires an evaluation record set corresponding to the usage pattern designated by the user from the evaluation comment DB (S1). For example, the inter-content relationship display apparatus acquires an evaluation record set corresponding to “usage form X”.

  A method for acquiring the evaluation record set will be specifically described. As shown in FIG. 4, when the usage form designated by the user is “examination of proposal contents”, the inter-content relationship display apparatus in the first embodiment uses the usage form “examination of proposal contents” from the usage form dictionary DB. The keyword “concept”, “system configuration”, etc. stored in association with are acquired. Then, the inter-content relationship display device searches for “evaluation comment” in the evaluation comment DB using the acquired keyword, and extracts an evaluation record corresponding to the evaluation comment including the keyword.

  For example, in the evaluation comment DB, “evaluator 1” evaluated the content identified by “content A.” The evaluation comment by “evaluator 1” is “Proposal of a new solution to a customer who is thinking about medical care” It memorizes an evaluation record “ Therefore, the inter-content relationship display apparatus extracts this as an evaluation record corresponding to an evaluation comment including the keyword “concept”. In addition, the evaluation comment DB “evaluator 1” evaluated the content identified by “content B.” The evaluation comment by “evaluator 1” is “expression of solution proposal materials to customers in the automotive industry. It memorizes an evaluation record “ Therefore, the inter-content relationship display device does not extract this as an evaluation record corresponding to an evaluation comment that does not include a keyword. In addition, the evaluation comment DB stores an evaluation record “evaluator 4 has evaluated the content identified by“ content B ”. There is no evaluation comment by“ evaluator 4 ”.” Therefore, the inter-content relationship display device does not extract this. The inter-content relationship display device makes the same determination for other evaluation records.

  Returning to FIG. 3, subsequently, the inter-content relationship display device acquires an evaluation record corresponding to the content set designated by the user from the acquired evaluation record set (S2). For example, the inter-content relationship display device selects evaluation records corresponding to the content sets “content A”, “content B”, “content C”, and “content D” specified by the user from the acquired evaluation record sets. get.

  Subsequently, the inter-content relationship display apparatus according to the first embodiment selects a representative evaluator who can express the main content relationship (S3). First, the inter-content relationship display device selects the inter-content relationship in which the number of evaluators who have evaluated all the contents included in the inter-content relationship exceeds a predetermined number. For example, the inter-content relationship display apparatus acquires six combinations such as “content A” and “content B”, “content A”, and “content C” as inter-content relationships.

  Subsequently, the inter-content relationship display device selects the inter-content relationship in which the number of evaluators who have evaluated all the contents included in the inter-content relationship exceeds a predetermined number. For example, it is assumed that the predetermined number is “1”. The evaluators who evaluated all of “content A” and “content B” are “evaluator 2” and “evaluator 3”, and the number of evaluators is “2”. The evaluator who evaluated all of “content A” and “content C” is only “evaluator 1”, and the number of evaluators is “1”. The evaluators who evaluated all of “content A” and “content D” are “evaluator 1” and “evaluator 3”, and the number of evaluators is “2”. There is no evaluator who evaluated all of “Content B” and “Content C”. The evaluator who evaluated all of “content C” and “content D” is only “evaluator 1”, and the number of evaluators is “1”. Therefore, the inter-content relationship display device selects “content A” and “content B”, and “content A” and “content D” as the inter-content relationship in which the number of evaluators exceeds “1”. That is, as shown in FIG. 3, the main content relationship is “content A” and “content B”, and “content A” and “content D”.

  Next, the content relationship display device evaluates, for each of the main content relationships, the popular content evaluated by the evaluator with a higher number of evaluators than the predetermined number of evaluators at a rate higher than the predetermined rate. Select a person. A method for selecting a representative evaluator will be specifically described. The inter-content relation display device counts the number of evaluators for each content based on the evaluation comment DB. For example, as shown in FIG. 5, the inter-content relationship display apparatus counts the number of evaluators for each content. Here, when the predetermined number of evaluators is “1”, contents other than “content C” and “content F” become popular contents.

  Subsequently, for each evaluator, the inter-content relationship display device counts the number of popular contents evaluated by the evaluator and the total number of contents evaluated by the evaluator. Then, the inter-content relationship display device calculates the influential degree of each evaluator by dividing the number of popular contents evaluated by the evaluator by the number of all contents evaluated by the evaluator. In other words, the ratio of the number of popular contents evaluated to the total number of contents evaluated is the influential degree. For example, regarding “evaluator 1”, the number of popular contents evaluated is “4”, and the total number of evaluated contents is “5”. For this reason, the inter-content relationship display device calculates the influential degree of “evaluator 1” as “0.80”. In addition, what was calculated by the other method may be used for an influential degree. For example, the ratio of the content to which the evaluation comment is given by the evaluator to the total content evaluated by the evaluator may be calculated and used as the influential degree.

  Returning to FIG. 3, in this way, the inter-content relationship display device sets a ratio higher than a predetermined ratio for popular content evaluated by evaluators with a higher number of evaluators than a predetermined number of evaluators for each of the main content relationships. Select the evaluator evaluated in. That is, the inter-content relationship display device selects at least one evaluator having a high degree of influence as a representative evaluator for each main content relationship. For example, the inter-content relation display device compares the influential degree of “evaluator 1” with the influential degree of “evaluator 3” for the main inter-content relations “content A” and “content D”, and the influential degree is high. “Evaluator 1” is selected as the representative evaluator. On the other hand, the inter-content relation display device compares the influential degree of “evaluator 2” with the influential degree of “evaluator 3” for the main inter-content relations “content A” and “content B”. “Evaluator 2” is selected as the representative evaluator.

  Then, the inter-content relationship display device in the first embodiment displays the correspondence between the representative evaluator selected in S3 and the designated content evaluated by the representative evaluator on the output unit (S4). For example, as shown in FIG. 3, the inter-content relationship display device expresses “evaluator 1” and “evaluator 2” and designated contents “content A” to “content D” as nodes, and the correspondence relationship. Is displayed by a bipartite graph that expresses

[Procedure for Processing by the Content Relationship Display Device in Embodiment 1]
Next, a processing procedure performed by the inter-content relationship display apparatus according to the first embodiment will be described with reference to FIGS. FIG. 9 is a diagram for explaining the flow of generation of secondary data. FIG. 10 is a diagram for explaining the flow of the usage mode estimation process. FIG. 11 is a diagram for explaining the flow of the evaluator's influential degree calculation process. FIG. 12 is a diagram for explaining the flow of display processing of the content set designated by the user. FIG. 13 is a diagram for explaining the flow of the representative evaluator extraction process.

[Flow of secondary data generation]
As shown in FIG. 9, first, the inter-content relationship display device 10 uses the evaluation comment DB 21 and the usage pattern dictionary DB 22 to infer the usage pattern of all evaluation records stored in the evaluation comment DB 21 and uses the content. Store in the form DB 24 (step S101). Subsequently, the inter-content relationship display device 10 calculates the influential degree of all evaluators for each usage form based on all evaluation records stored in the content usage form DB 24 and stores it in the evaluator influential degree DB 26 (step). S102).

[Flow of guessing process of usage type]
Next, the process of step S101 in FIG. 9 will be described in detail. As shown in FIG. 10, the inter-content relationship display device 10 first acquires one evaluation record from the evaluation comment DB 21 (step S101-1). Next, the inter-content relationship display apparatus 10 acquires one usage pattern and a keyword of the usage pattern from the usage pattern dictionary DB 22 (step S101-2).

  Then, the inter-content relationship display apparatus 10 determines whether or not the evaluation comment of the evaluation record acquired in step S101-1 includes the keyword acquired in step S101-2 (step S101-3). As a result of the determination, if it is included (Yes at Step S101-3), the inter-content relationship display device 10 identifies the evaluation record, the identifier that identifies the content, the identifier that identifies the evaluator, and the acquired usage. The form is stored in the content usage form DB 24. On the other hand, if it is not included as a result of the determination (No at Step S101-3), the process proceeds to Step S101-5.

  Thereafter, the inter-content relationship display apparatus 10 determines whether or not all usage forms have been acquired from the usage form dictionary DB 22 (step S101-5), and if not acquired (No in step S101-5), The process returns to step S101-2. On the other hand, if acquired (Yes at Step S101-5), the inter-content relationship display apparatus 10 determines whether or not all evaluation records have been acquired from the evaluation comment DB 21 (Step S101-6). If not acquired (No at Step S101-6), the process returns to Step S101-1. On the other hand, if acquired (Yes at step S101-6), the process is terminated.

[Flow of process for calculating evaluator's influential degree]
Next, the process of step S102 in FIG. 9 will be described in detail. As illustrated in FIG. 11, the inter-content relationship display apparatus 10 acquires all evaluation records corresponding to one usage mode (denoted u) from the content usage mode DB 24 (step S102-1). Next, the inter-content relationship display apparatus 10 aggregates the number of evaluators of each content using the evaluation record acquired in step S102-1, and the content set D (the number of evaluators is a predetermined number α or more). u, α) is extracted (step S102-2).

  Subsequently, the inter-content relationship display device 10 determines whether or not the content set D (u, α) is not an empty set (at least one content evaluated by more than α evaluators exists) (step) S102-3). As a result of the determination, if the content set D (u, α) is not an empty set (No at Step S102-3), the inter-content relationship display device 10 adds the evaluation record acquired from the content set D (u, α). The content set V (u, α, e) evaluated by the included evaluator (e) is extracted (step S102-4).

  The inter-content relationship display apparatus 10 determines whether the content set V (u, α, e) is not an empty set (e is evaluating at least one content evaluated by α or more evaluators). Is determined (step S102-5). As a result of the determination, if the content set V (u, α, e) is not an empty set (No at Step S102-5), the inter-content relationship display device 10 determines the efficiencies S (u) of the evaluator e in the usage mode u. , α, e) is calculated and stored in the evaluator competency DB 26 (step S102-6).

  Here, the inter-content relationship display apparatus 10 sets the number of contents in the content set V (u, α, e) to | V (u, α, e) | 0, e) |, | V (u, α, e) | ÷ | V (u, 0, e) | This value shows a higher value as the evaluator evaluates the content having a larger number of evaluators at a higher ratio. Alternatively, the weight a (u, c) of the content c is set so that the content evaluated by many evaluators shows a higher value, and (Σa (u, c)) ÷ | V (u, 0, e) | (C∈V (u, α, e)) may be used as the power S (u, α, e). a (u, c) is, for example, a threshold number sequence of the number of evaluators n (n1, n2,..., nk = α) (n1> n2>...> nk = α) and a weight number sequence w (w1, w2,. , wk) (w1> w2>...> wk) and if the number of evaluators of c in u is n (x) or more, a (u, c) = w (x). Alternatively, the logarithm of the number of evaluators of c in u may be a (u, c).

  Subsequently, the inter-content relationship display apparatus 10 determines whether or not the influential degrees of all evaluators have been calculated (step S102-7). If not calculated (No at Step S102-7), the process returns to Step S102-4. On the other hand, when it is calculated (Yes at Step S102-7), the inter-content relationship display device 10 determines whether or not all usage forms have been acquired (Step S102-8). If not acquired (No at Step S102-8), the process returns to Step S102-1. If acquired (Yes at step S102-8), the process is terminated. This completes the secondary data generation process.

[Flow of display processing of content set specified by user]
Next, the flow of the designated content display process will be described. As illustrated in FIG. 12, in the inter-content relationship display device 10, the evaluation record acquisition unit 31 acquires a specified usage form and a specified content set by being input by a user (step S <b> 201).

  Subsequently, the evaluation record acquisition unit 31 acquires an evaluation record set corresponding to the usage mode designated by the user from the content usage mode DB 24 (step S202).

  The main content relationship selection unit 32 and the representative evaluator selection unit 33 can represent the main content relationship (a combination of content having many common evaluators) based on the evaluation record set and the evaluator's influentiality. An evaluator is extracted (step S203).

  Next, the bipartite graph display unit 34 displays the correspondence between the representative evaluator and the designated content in the form of a bipartite graph (step S204). When the bipartite graph display unit 34 receives a content browsing instruction from a user referring to the bipartite graph, the bipartite graph display unit 34 acquires the content for which the browsing instruction has been received from the content DB 23 and presents the content to the user (step S205). .

[Flow of representative evaluator extraction process]
Next, the process of step S203 in FIG. 12 will be described in detail. As illustrated in FIG. 13, the main content relationship selection unit 32 creates a set (P) of content pairs that have been evaluated by the common evaluator based on the evaluation record set acquired in step S202 ( Step S203-1).

  Subsequently, the main content relationship selection unit 32 sorts P in descending order of the number of common evaluators (step S203-2). Then, the main content relationship selection unit 32 initializes the representative evaluator set W to an empty set (step S203-3).

  Next, the representative evaluator selection unit 33 acquires the first content pair (referred to as r) of P (step S203-4). Hereinafter, the common evaluator set for r is B (r).

  The representative evaluator selection unit 33 determines that the product set of B (r) and W is an empty set (no common evaluator of r has been selected as a representative evaluator yet) (step S203— 5), the evaluator with the highest influential value in the common evaluator set B (r) is added to W (step S203-6).

  Then, the representative evaluator selection unit 33 excludes r from P (step S203-7), and when P is not an empty set (all content pairs have not yet been acquired) (No at step S203-8). The process returns to step S203-4. On the other hand, if P is an empty set (Yes at step S203-8), the process ends.

[How to display a bipartite graph]
By the way, below, the display method of the bipartite graph by the content relationship display apparatus in Example 1 is illustrated. FIG. 14 is a diagram for explaining an example of a content-evaluator relationship display method. FIG. 15 is a flowchart for explaining the display method. FIG. 16 is a diagram for explaining an example of a content-evaluator relationship display method. FIG. 17 is a flowchart for explaining the display method. FIG. 18 is a diagram for explaining an example of a content-evaluator relationship display method. FIG. 19 is a flowchart for explaining the display method. FIG. 20 is a diagram for explaining an example of a content-evaluator relationship display method. FIG. 21 is a flowchart for explaining the display method. FIG. 22 is a diagram for explaining an example of a content-evaluator relationship display method. FIG. 23 is a flowchart for explaining the display method.

  First, the display example of FIG. 14 will be described. The bipartite graph display unit 34 according to the first embodiment displays the representative evaluator and the designated content in the form of a bipartite graph that expresses the correspondence between the representative evaluator and the designated content with an edge. . In addition, when the bipartite graph display unit 34 represents the representative evaluator as a node, the bipartite graph display unit 34 compares the efficiencies between the representative evaluators based on the evaluator inefficiency DB 26, and determines the evaluator with the higher influential degree. Display with emphasis over the evaluator who has the lower power. For example, it is emphasized by a change in size or color and displayed so that a powerful evaluator can understand at a glance.

  In addition, the bipartite graph display unit 34 compares the number of evaluators between the designated contents based on the evaluator number DB 25 when expressing the designated content with nodes, and evaluates the content having the larger number of evaluators. Display with emphasis over the smaller content. For example, it is emphasized by a change in size or color and displayed so that popular content (content with a large number of evaluators) can be seen at a glance.

  Specifically, as shown in FIG. 15, the bipartite graph display unit 34 first acquires a representative evaluator (step S <b> 301), and based on the evaluator influential DB 26, determines the influential degree between the representative evaluators. Compare (step S302). And the bipartite graph display part 34 emphasizes and displays the evaluator with a higher influential degree than the evaluator with a lower influential degree (step S303). Subsequently, the bipartite graph display unit 34 acquires the designated content (step S304), and compares the number of evaluators between the designated content based on the evaluator number DB 25 (step S305). Then, the bipartite graph display unit 34 displays the content with the larger number of evaluators more emphasized than the content with the smaller number of evaluators (step S306).

  According to this display method, the inter-content relationship display device 10 presents a content usage pattern of a powerful evaluator (an evaluator whose most evaluated content is a popular content evaluated by many evaluators). Is possible. For this reason, the user can easily find hidden useful content or content that is likely to become popular in the future with reference to the usage patterns of leading evaluators. In addition, since it is possible to present a usage pattern of a powerful evaluator in the usage mode specified by the user, it becomes easy for the user to find useful content in a problem during use.

  Next, the display example of FIG. 16 will be described. The first display control unit 35 according to the first embodiment displays peripheral content (evaluation content not included in the designated content) of the evaluator designated by the user.

  Specifically, as shown in FIG. 17, the evaluator selection instruction receiving unit 35a receives an input of a selection instruction for selecting an evaluator displayed on the output unit 12 (Yes in step S401). Then, the peripheral content addition display unit 35b acquires content (peripheral content) that is evaluated by the evaluator selected by the selection instruction and is not yet displayed on the output unit 12 based on the evaluation comment DB 21. (Step S402).

  The peripheral content addition display unit 35b adds and displays the acquired peripheral content as a node in the bipartite graph (step S403), and adds the correspondence between the evaluator and the added peripheral content as an edge. It is displayed (step S404).

  According to this display method, the inter-content relationship display apparatus 10 can present peripheral content that is content evaluated by a powerful evaluator and is not included in the designated content set. This makes it easy for the user to find useful content that has not been specified.

  Next, the display example of FIG. 18 will be described. The second display control unit 36 according to the first embodiment reselects and re-displays the representative evaluator based on the designated content set edited by the user's instruction.

  Specifically, as shown in FIG. 19, the evaluator selection instruction receiving unit 36 a receives an input of a selection instruction for selecting an evaluator displayed on the output unit 12 in the output unit 12 (Yes in step S <b> 501). Alternatively, the content deletion instruction receiving unit 36b receives an input of a deletion instruction for deleting the content displayed on the output unit 12 in the output unit 12 (Yes in step S501).

  Then, when the input of the selection instruction is received by the evaluator selection instruction receiving unit 36a, the new content set acquisition unit 36c acquires the peripheral content of the selected evaluator based on the evaluation comment DB 21 (step S502). Then, the new content set acquisition unit 36 c acquires a content set including peripheral content as a new content set and re-inputs it to the evaluation record acquisition unit 31.

  On the other hand, the new content set acquisition unit 36c acquires a content set that does not include the deleted content as a new content set and receives an evaluation record when the input of the deletion instruction is received by the content deletion instruction reception unit 36b. Re-input to part 31.

  Then, the main content relationship selection unit 32 reselects the main content relationship in the new content set (step S503), and the representative evaluator selection unit 33 reselects the representative evaluator (step S504). Then, the bipartite graph display unit 34 redisplays the correspondence relationship between the reselected evaluator and the content evaluated by the evaluator on the output unit 12 (step S505).

  According to this display method, the user edits the designated content by adding the peripheral content of the evaluator designated by the user or deleting the content judged not useful by the user. The inter-content relationship display device 10 can select and present a powerful evaluator based on the content set selected by the user. For this reason, the user selects useful content to some extent with reference to the usage patterns of leading evaluators, and then uses another evaluator who is more suitable for expressing the relationship between the main contents of the selected content set as a clue. Useful content can be found.

  Next, the display example of FIG. 20 will be described. The third display control unit 37 according to the first embodiment inputs the specific content of interest by the user, and displays the evaluator selected by the user from the list of evaluators of the content of interest added to the bipartite graph.

  Specifically, as shown in FIG. 21, the content selection instruction accepting unit 37a accepts an input of a content selection instruction for selecting the content (target content) displayed on the output unit 12 (Yes in step S601). ).

  Then, the attention content evaluator acquisition unit 37b acquires the evaluator who evaluated the attention content and the content evaluated by the evaluator based on the evaluation comment DB 21 (step S602).

  Then, the evaluator influential order display unit 37c displays, for each evaluator of the content of interest, the correspondence between the evaluator, the influential degree, and the evaluation content on the output unit 12 in descending order of the influential degree (step S603). That is, the evaluator influential order display unit 37c displays a list of evaluators of the content that the user pays attention to in the order of evaluators with the highest influential degree. The list includes an identifier for identifying an evaluator, a degree of influence, and a list of evaluation contents included in the designated content set.

  Subsequently, the evaluator selection instruction accepting unit 37d accepts an input of a selection instruction for selecting an evaluator in the list displayed on the output unit 12 in the output unit 12 (Yes in step S604). Then, the evaluator addition display unit 37e adds and displays the selected evaluator as a node (step S605), and adds and displays the correspondence between the evaluator and the evaluation content as an edge (step S606). .

  According to this display method, the evaluator selected by the user from the evaluators of the content of interest can be added to the bipartite graph. For this reason, when it is determined that one content is useful, the user selects an evaluator who tends to evaluate the content more suitable for his / her interest from the evaluators of the content, and evaluates the evaluation. It will be possible to discover useful content with reference to the usage patterns of the users.

  Next, the display example of FIG. 22 will be described. The fourth display control unit 38 according to the first embodiment can switch the display to a partial graph format in which the content is represented by a node and the relationship between main contents is represented by an edge. In addition, the fourth display control unit 38 adds the evaluator selected by the user from the list of common evaluators of the relationship between the attention contents, to the bipartite graph, by designating the relationship between the attention contents. indicate.

  Specifically, as shown in FIG. 23, the non-display instruction receiving unit 38a receives a non-display instruction instructing not to display the evaluator displayed on the output unit 12 in the output unit 12 (Yes in step S701). .

  Then, the inter-content relationship display unit 38b displays only the correspondence between the content and the content on the output unit 12 (step S702). That is, the content relationship display unit 38b switches to a partial graph format display in which the content is represented by a node and the main content relationship is represented by an edge in accordance with a user instruction.

  Then, the inter-content relationship selection instruction accepting unit 38c accepts an input of a correspondence selection instruction for selecting the correspondence displayed on the output unit 12 in the output unit 12 (Yes in step S703).

  Then, based on the evaluation comment DB 21, the attention content relationship evaluator acquisition unit 38 d acquires the evaluator who evaluated all of the selected correspondence content and the content evaluated by the evaluator (step S 704).

  Subsequently, the evaluator influential order display unit 38e displays, for each acquired evaluator, the correspondence between the evaluator, the influential degree, and the evaluation content on the output unit 12 in descending order of influential degree (step S705). . That is, the evaluator influential order display unit 38e displays a list of common evaluators of the relationship between contents that the user pays attention to in order of evaluators with the highest influential degree. The list includes a list of evaluation contents included in the identification name of the evaluator, the degree of influence, and the specified content set.

  Next, the evaluator selection instruction accepting unit 38f accepts an input of a selection instruction for selecting an evaluator displayed on the output unit 12 in the output unit 12 (Yes in step S706).

  Then, the evaluator addition display unit 38g adds and displays the selected evaluator as a node (step S707), and adds and displays the correspondence between the evaluator and the content as an edge (step S708).

  According to this display method, the evaluator selected by the user from the common evaluators of the relationship between the contents of interest can be added to the bipartite graph. For this reason, when it is determined that two specific contents are useful, the user tends to evaluate the contents more suitable for his / her interest from among the evaluators using both of the contents. By selecting an evaluator and referring to the usage pattern of the evaluator, useful content can be found.

[Effect of Example 1]
As described above, the inter-content relationship display apparatus according to the first exemplary embodiment is configured to display content that is often used by a common evaluator from combinations of content in a content set (specified content set) specified by a user. Select combinations (relationships between main contents). Furthermore, the inter-content relationship display device extracts evaluators (potential evaluators) who tend to carefully select and use popular contents (contents that are likely to be used by many evaluators). The inter-content relationship display device includes two parts in which an edge (corresponding to an evaluation comment) connects a node representing content and a node representing a representative evaluator (a leading evaluator included in a common evaluator of the relationship between main contents). Express with graphs.

  For this reason, according to the inter-content relationship display device in the first embodiment, it is possible to appropriately present highly useful content to the user. That is, according to the inter-content relationship display device in the first embodiment, the usage pattern of content of a powerful evaluator (evaluator who is a popular content evaluated by many evaluators) is visualized. It becomes possible to present. For this reason, the user can easily find hidden useful content or content that is likely to become popular in the future with reference to the usage patterns of leading evaluators. In addition, the effect for each display method when visualizing and presenting is as described in the description of the display method of the bipartite graph.

  Further, the inter-content relationship display apparatus according to the first embodiment accepts designation of a usage form (designated usage form) from a user. Then, the inter-content relationship display device extracts a prominent evaluator in the designated usage form based on an evaluation record having an evaluation comment including a keyword relating to the designated usage form, and selects a main inter-content relation in the designated usage form.

  For this reason, according to the inter-content relationship display device in the first embodiment, it is possible to present a usage pattern of a powerful evaluator in the usage mode specified by the user. For this reason, it becomes easy for a user to find useful content in the subject at the time of utilization.

  Furthermore, when the user selects content, for example, it is assumed that there is one content that the user has determined to be useful. According to the inter-content relationship display apparatus in the first embodiment, the user selects a representative evaluator who tends to have a relationship with content close to the user's interest from representative evaluators having a relationship with the content of interest. Can do. Therefore, the user can examine useful contents from other contents related to the representative evaluator. This makes it possible to efficiently discover content useful for the user.

[Other embodiments]
Although the embodiments of the present invention have been described so far, the present invention may be implemented in various different forms other than the embodiments described above.

  So far, as the first embodiment, a case has been described in which the inter-content relationship display device is applied to a system in which an evaluator evaluates content. However, the present invention is not limited to this, and the inter-content relationship display device can be similarly applied to any system as long as the system uses the content.

  For example, an inter-content relationship display device is designed to improve the efficiency of work and improve the quality of deliverables by sharing documents created in the work of the organization with members within the organization and sharing them with each other. It is thought that it will be utilized in a simple information sharing system.

  In other words, in an organization that provides services and solutions to customers, another member can use proposals and other materials created by a member of an organization for a specific customer using an information sharing system. Something is shared in a form. It is expected to improve the efficiency of material creation for customers with similar characteristics and to achieve uniform material quality at a high level (FIG. 24).

  In such information sharing, the usage (usage characteristics) of the shared material differs depending on the user (FIG. 25). For example, there are users who obtain a large number of shared materials at random and then select useful content by examining the contents of the obtained shared materials. In addition, there are users who obtain the shared material after referring to the reputation and titles heard by the people in advance and identifying the shared material that is likely to be useful. The usage history of the latter user's shared material is helpful in searching for useful content, but the usage history of the former user is not very helpful.

  Furthermore, the usage form of the shared material greatly depends on the problem that the user has when accessing the information sharing system (FIG. 26). For example, when a solution (such as an information system with a configuration suitable for solving a customer's problems) is proposed to the customer according to the vague needs of the customer, the content of the shared material ( Based on the idea and system configuration that is the basis of the proposal, it is possible to use it as an example of an expression format for expressing the proposal contents in an easy-to-understand manner at the stage of writing the material.

  For this reason, in such an information sharing system, it has been difficult for the user to efficiently find useful related content only by conventional related content recommendation. In other words, even if some related content of the content currently focused on is recommended, there is a possibility that the usage history of the user who is not helpful in searching for useful content is the basis. Also, not all content is useful for the problem at that time of the user. For this reason, users do not search for useful content by referring to the contents of each content, profile information added to each content (metadata describing the characteristics of the material), evaluation information of other users, etc. I didn't.

  If the inter-content relationship display device is applied to such an information sharing system, highly useful content can be appropriately presented to the user. That is, according to the inter-content relationship display device, it is possible to visualize and present the usage pattern of the content of a powerful user (a user who is a popular content that is used by many users). It becomes possible. For this reason, the user can easily find hidden useful content or content that is likely to become popular in the future with reference to the usage patterns of leading evaluators.
