Description

  The present invention relates to an information presentation device, an information presentation method, and an information presentation program, and more particularly to an information presentation device, an information presentation method, and an information presentation program for selecting a content desired by a user from stored content.

  Conventionally, as an information presentation device that selects and presents content desired by a user, a set of content that matches the user's request is generated from the stored content, and the set of generated content is sorted in dictionary order or price There is known an information presentation apparatus that sorts and presents according to some standard such as order.

  Specifically, for example, an EC (electronic commerce) site represented by Amazon (registered trademark: http://www.amazon.co.jp/) presents a content list narrowed down by a search keyword specified by the user. In this case, there is a method to present the contents list after sorting the relevant contents according to sales order, price order, release date order, title dictionary order, user preference order, content importance order, etc. Many have been adopted (hereinafter, this method is called a simple sorting method).

  Here, Patent Document 1 describes a technique relating to the combined use of the degree of matching (the degree of matching) of how much the search keyword matches the content and the sorting order such as sales order, price order, release date order, etc. Has been.

  Also, in this Patent Document 1, a method of sorting content that does not fall within the range of suitability specified in paragraph [0020] after removing it from the result, or the sorting order is the same as in paragraph [0023]. In such a case, a technique for displaying content with a high degree of fitness at the top is described.

  Patent Document 2 describes a method of sorting contents according to a user's search history.

  And in this patent document 2, after changing a search condition to paragraph [0037] and performing a search several times, based on the some search result memorize | stored in the search result memory | storage part, it is predetermined rank for every content. For each content on the basis of the method of sorting the content included within (for example, within the top five) and sorting in order from the content with the largest number of times counted, or a plurality of search results stored in the search result storage unit Each time the rank is added, and the total value obtained by adding the ranks, for example, in the case of ranking 2nd, 3rd, 1st in each of the three searches, the total value is calculated as 6 and A method of sorting in order from content of higher rank is described.

  Therefore, this Patent Document 2 describes a method of sorting higher the content presented so far.

Further, this Patent Document 2 also discloses a technique for separating unread content and read content into separate areas and displaying them as a technique for easily displaying unread content in paragraph [0050] or the like. Is also described.

  However, the conventional method (the above-described simple sorting method) for generating a content list by a sorting method prepared in advance is not always easy to use for the user and the service provider.

  This is because, for example, a case where the contents are sorted and presented in the sales order will be described as an example. Even if the search keyword is changed and the contents are searched, the popular contents are often presented at the top.

  For this reason, there is no desired content in the content list searched and presented by the search keyword KWD1, and even if the content is searched by changing to the search keyword KWD2, there is no significant change in the content presented at the top of the content list. A case has arisen.

  Therefore, from the user's standpoint, although the search keyword is changed in order to search for another content, there is no significant change in the content presented at the higher level, so the desired content cannot be found. There is a problem.

  Further, when considering from the service provider side, content that is easily presented to the user is biased to specific content.

  Although it is important for service providers to present more content in order to increase the sales of content, content that is positioned at the bottom of the ranking is generated due to the bias in the content introduced. There is a problem that it is difficult to increase sales.

  Here, the case where the content that can be presented by the simple sorting method is biased will be described in detail using a specific example.

  In the EC site as described above, a user designates a search keyword, and contents that match the designated search keyword are sorted in order of sales.

  Then, three search results are presented on one page.

  In this case, a certain user searches the content with the search keyword KWD1 and the content set R1 = {c1, c2, c3,..., C9} is obtained as a search result, and c1, c2, c3,. Suppose they are sorted in order.

  That is, when the first page of the search result is presented, c1, c2, and c3 are presented. When the second page is presented, c4, c5, and c6 are presented, and the third page is presented. When this is done, c7, c8, and c9 are presented.

  Here, at the stage where the first page of the search result is presented, the user searches by changing the search keyword to KWD2, and the content set R2 = {c1, c2, c3, c10, c11, c12} is obtained. Assume that sorting is performed in the order of c1, c2, c3, c10, c11, and c12.

  That is, when the first page of the search result is presented, c1, c2, and c3 are presented, and when the second page is presented, c10, c11, and c12 are presented.

  Here, when the intention of the user's search behavior is estimated, the search keyword is searched again with KWD1 after the search keyword is searched with KWD1, and the contents c1, c2, and c3 searched and presented with the search keyword KWD1 are displayed. Since it was not the desired content, it is presumed that the search keyword was changed and searched.

  However, when a search is subsequently performed using the search keyword KWD2 after a search using the search keyword KWD1, the conventional content search service presents c1, c2, and c3 as search results presented first.

  Thus, even if the search keyword is changed and searched, only the same content information can be obtained on the first page, and in order to obtain different content information, it is necessary to refer to the second and subsequent pages of the search page. There is.

  This is a problem due to the fact that the contents are presented by sorting in a fixed manner using only the attributes of the contents without considering the situation such as the content presentation history and the user's search intention.

  Further, in Patent Document 1, in addition to sorting by a simple sorting method, sorting is performed with reference to the degree of matching between a search keyword and content.

  This case also has the same problems as the simple sorting described above.

  Specifically, for example, in a moving image content search service, let us consider a case where the content searched for “Horror” is not liked and the search is performed again using “Splatter”.

  In this case, if “horror” and “splatter” are interpreted as close meanings on the system side, the content sorted higher by “horror” is also sorted higher by “splatter”.

  However, from the user's point of view, even though the search method has been changed from “Horror” to “Splatter”, content similar to the content that appeared in “Horror” is preferentially displayed. Therefore, although the search keyword is changed in order to search for another content, there is no significant change in the content presented at the higher level, so the problem that the desired content cannot be found occurs. To do.

  In addition, as described in Patent Document 2, even if the method is to sort higher in the content that has been presented so far, similar to the simple sorting method and the method described in Patent Document 1, Although the search keyword is changed in order to search for the content, there is no significant change in the content presented at the higher level, which causes a problem that the desired content cannot be found.

  These methods of sorting the higher the content that has been presented so far are considered useful when analyzing the characteristics of the content. This is a technique that is not suitable for searching through window shopping.

  Further, Patent Document 2 describes a method of separately displaying unread content and read content in separate areas in order to clearly present unread content to the user. However, with this sorting method that separates unread and read content and displays different areas, there is a sufficient problem that the user refers only to unread content and does not refer to any read content.

  Further, from the user's perspective, even if the content is already read, there is a case where the content that has passed for a long time since the reference has been stored is weak, so that it may be desired to read it again.

  However, if the read content is separated from the unread content, the read content is displayed in the read content area even though the memory of the read content is weakened. It may be better to display it as if it were unread.

  Further, when considering from the service provider side, there is a possibility that the content that has been read once may be extremely reduced in the chances for the user to refer to it. That is, since it is assumed that the re-challenge opportunity obtained by re-reading the content that has already been read is lost, there is a problem that sales of the content are sluggish.

  The present invention has been made in view of the above problems, and an information presentation apparatus, an information presentation method, and information that can introduce a large amount of content to a user by preferentially presenting unpresented content. The purpose is to provide a program for presentation.

An information presentation apparatus, an information presentation method, and an information presentation program that can present content can be realized.

The best mode for carrying out the present invention will be described in detail with reference to the drawings.
[First Embodiment]
(1) Configuration of Information Presentation Device FIG. 1 is a configuration diagram of an information presentation device showing a first embodiment for carrying out the present invention.

  In the information presentation apparatus shown as the first embodiment, a content storage unit 1 that stores content information to be presented, a condition instruction unit 2 that determines conditions for selecting content, and a content selection condition determined by the condition instruction unit 2 The content list generation unit 3 that generates a content list from the contents stored in the content storage unit 1 and the content list generated by the content list generation unit 3 are presented to the user, and the user can browse the content. The content list presenting unit 4 for performing the above and the presentation history managing unit 5 for managing the content list generated by the content list generating unit 3 and the information presenting history in the content list presenting unit 4 are provided.

  The content list generation unit 3 finds whether the content selection condition determined by the condition instruction unit 2 is a content selection condition presented in the past, and the corresponding content selection condition is found by the condition verification unit 31. If there is no content, the content selection unit 32 that selects content that satisfies the content selection condition from the content stored in the content storage unit 1, and the content selected by the content selection unit 32 in order of popularity, price, dictionary, etc. The sort order determined by the base sorting unit 33 with reference to the presentation status of each content stored in the base sorting unit 32 and the presentation history management unit 5 is corrected, and the content not presented to the user is given priority. And a correction sorting unit 34 for correcting the sorting so as to present That.

The presentation history management unit 5 stores the content list generated by the content list generation unit 3 together with the content selection conditions, and further stores the content list presentation state and the user browsing history in the content list presentation unit 4 as presentation history information. A presentation history storage unit 51 that performs the extraction, a condition-designated presentation history extraction unit 52 that extracts a content set with a presentation order from the presentation history information stored in the presentation history storage unit 51 using a content selection condition as a key, and a presentation history storage Using the content as the key from the information stored in the unit 51, what number the search condition was sorted by which search condition, whether the content was presented to the user by the content list presentation unit 4, and further selected by the user And a content designation / presentation history extraction unit 53 for extracting information such as.
(2) Operation of Information Presentation Device FIG. 2 is a flowchart showing the operation of the information presentation device in the first embodiment of the present invention. The operation in the first embodiment will be described with reference to FIG.

  First, in step S101, the condition instruction unit 2 sets content selection conditions. Specifically, for example, as a method for setting the content selection condition, a method in which a user sets a search keyword, a method in which the system automatically sets using various recommendation engines such as collaborative filtering, and the like can be considered. Any method is acceptable.

  After setting the conditions, the process proceeds to step S102. In step S102, the condition collating unit 31 collates whether the content selection conditions set by the condition instructing unit 2 have been used in the past.

  This collation is performed via the condition designation presentation history extraction unit 52.

  The condition designation presentation history extraction unit 52 extracts a history related to the content selection condition from the presentation history stored in the presentation history storage unit 51. The range of the history to be verified is assumed to be within the same session, within a fixed time such as within 24 hours, or unlimited, etc., and the user basically assumes the history of the same user. It is assumed that the history range for collation is set by the service.

  When a history is found in the condition designation presentation history extraction unit 52, the content selection condition and the content with the presentation order are sent from the condition designation presentation history extraction unit 52 to the condition matching unit 31. In this case, the process proceeds to step S108.

  On the other hand, when the history is not found in the condition designation presentation history extraction unit 52, for example, information indicating that no empty set is found is sent from the condition designation presentation history extraction unit 52 to the condition matching unit 31. In that case, the process proceeds to step S103.

  Since the condition collating unit 31 determines that the content selection condition set by the condition instructing unit 2 has not been used in the past, in step S103, the content selecting unit 32 causes the content storage unit 1 to Then, the content that matches the content selection condition set by the condition instruction unit 2 is selected.

  Then, the content selection unit 32 sends the selected content to the base sorting unit 33, and proceeds to step S104.

  In step S104, the base sorting unit 33 sorts the content selected by the content selection unit 32 using a sorting method (called a base sorting method) such as a predetermined popularity order, price order, dictionary order, or the like. Then, the process proceeds to step S105.

  In the present invention, the sorting method used in the base sorting unit 33 does not affect the effects of the present invention, so any sorting method may be used.

  In step S <b> 105, the correction sorting unit 34 obtains a presentation history for each content sent from the base sorting unit 33. The content presentation history acquisition is performed via the content designation presentation history extraction unit 53.

  The content designation presentation history extraction unit 53 extracts the presentation history of each content from the presentation history stored in the presentation history storage unit 51. The range of the target history is assumed to be unlimited within a certain time, such as within 24 hours, within the same session, and the user basically targets the history of the same user.

  However, the range of the target history is merely an example and is not limited thereto, and the target history range is set by the service.

  In step S106, the correction sorting unit 34 refers to the presentation history of each content acquired via the content designation presentation history extraction unit 53, and sorts the content sorted by the base sorting unit 33 using the presentation history. Correct the order.

  In this correction, priority is given to content that has not been presented to the user, and correction is made so that the content is placed higher in the content list.

  Here, an example of a correction method in the correction sorting unit 34 is shown. The correction sorting unit 34 acquires a presentation history for each content to be presented via the content designation presentation history extraction unit 53 of the presentation history management unit 5. Then, the obtained presentation history is sorted in the order from the smallest history (in ascending order).

  As described above, the correction sorting unit 33 sorts the content with the same number of presentation histories by sorting with a stable algorithm such as the distribution counting sort, so that the order of sorting by the base sorting unit 33 is maintained.

  Here, the distribution count sort is a sort method that can be used when the data value is within a certain range, and is a sort method that converts the frequency distribution of the data into ranks and reinserts the data into the corresponding ranks. To tell.

  This correction sorting method (distribution counting sort) is an example, and another method is used to prioritize content that has not yet been presented to the user and place it at the top of the content list. Also good.

  In step S107, the content selection condition and the content set with a presentation order are stored in the presentation history storage unit 51.

  In step S108, the content list presentation unit 4 presents a content list. This list is generated in accordance with the presentation order sorted by the correction sorting unit 34 or the presentation order sent from the condition matching unit 31 and presented to the user.

  In addition, the content presented to the user on this content list page is recorded in the presentation history of the presentation history storage unit 51. If the content does not fit on one page due to the content presentation area, the content list page is divided into a plurality of pages.

  Further, when the content list page is divided into a plurality of pages, it is desirable to record that only the content included in the actually displayed content list page has been presented. Then, the process proceeds to step S109.

  If the page selection operation such as next page presentation / all page presentation occurs when the content selection or content list page is divided into a plurality of pages, the content list presentation unit 4 performs processing according to the user's interaction. I do.

  Then, the process proceeds to step S110, and the content of the interaction performed in step S109 is recorded in the presentation history storage unit 51.

  Specifically, for example, when a page turning operation occurs as an interaction from the user, the content list presentation unit 4 updates the content list page and records information indicating that the content is presented in the presentation history storage unit 51. To do.

  As another example, when the user selects the detailed information presentation of content from the content included in the content list page, information indicating that the content has been presented in detail is recorded in the presentation history storage unit 51. To do.

  Then, the process proceeds to step S111, and if the user changes the content selection condition so as to change the way of searching for the content, the process returns to step S101. Otherwise, the process returns to step S108, and the content list is continuously displayed to the user. Present.

Here, the determination is made based on whether or not the content selection condition has been changed. However, in the present embodiment, the determination is not limited to this, and a determination as to whether or not to stop the content selection is further provided. May be.
(3) Effects of the First Embodiment As described above, in the information presentation apparatus according to the present invention, the content is sorted based on the content presentation history, and the content that has been presented under another content selection condition has priority during sorting. The order can be lowered and the priority order of unpresented content can be increased.

  By adopting this mechanism, the user can know different types of content by changing the selection method.

Furthermore, from the viewpoint of the service provider, more content can be presented to the user, so that not only popular content but also so-called long tail products can be introduced to the user, and the user's access to the service is activated. This has the effect of increasing the number of content users of the entire service.
(4) Examples
[Example 1 of the first embodiment]
A first example will be described as a first example in the first embodiment.
(4-1) First Example FIG. 3 shows an example of content information stored in the content storage unit 1. In the example of FIG. 3, content data 100 in which video content is the presentation target content is stored in the content storage unit 1. The content data 100 stores attribute values such as a content ID (identifier), a title, a genre, a recommendation degree, and a popularity degree for each content.

  The content data 100 is an example of content information stored in the content storage unit 1, and the storage form is not limited to the embodiment as long as the content search is possible. It may be.

  FIG. 4 shows an example of presentation history information stored in the presentation history storage unit 51. FIG. 4 is an example of a case where the presentation history information 101 when the user browses the content data 100 shown in FIG. 3 is stored. In the example of FIG. 4, the presentation history information 101 includes a content selection condition-content list correspondence table 1011 and a content-history correspondence table 1012.

  The content selection condition-content list correspondence table 1011 stores a content selection condition for each user and a content list under the content selection condition.

  The content-history correspondence table 1012 stores the number of times of presentation of each content and the number of times of browsing detailed information for each user. Note that the browsing history information 101 shown in FIG. 4 is an example in the embodiment of the present invention. The content list generated by the content list generation unit 3 is stored together with the content selection conditions, and the content list is displayed by the content list presentation unit 4. Any form can be used as long as the state and the user's browsing history can be stored.

  Next, the operation of the first embodiment will be described with reference to the flowchart of FIG.

  Here, content data 100 is stored in the content storage unit 1, presentation history information 101 is stored in the presentation history storage unit 51, and the user USER-01 uses the information presentation device. It will be explained as a thing.

  First, in step S101, the condition instructing unit 2 sets “genre = animation” as a content selection condition by the user, and proceeds to step S102.

  In step S102, the condition collating unit 31 collates whether the content selection condition “genre = animation” set in the condition instructing unit 2 has been used in the past. This collation is performed via the condition designation presentation history extraction unit 52.

  In this case, the condition-designated presentation history extraction unit 52 refers to the content selection condition-content list correspondence table 1011 in the presentation history information 101 stored in the presentation history storage unit 51 and uses the content as the presentation history of the user USER-01. The selection condition “genre = animation” and the content list (in order of presentation) “CONT-01, CONT-2, CONT-03” are sent to the condition matching unit 31 and the process proceeds to step S108.

  In step S108, the content list presentation unit 4 presents a content list. This list is generated according to the order sent from the condition matching unit 31.

  FIG. 5 shows a case where a presentation example of this content list is displayed on an information presentation screen (not shown). In addition, the fact that the contents CONT1-01, CONT-02, and CONT-03 are presented in the presentation history of the presentation history storage unit 51 is also recorded. FIG. 6 shows an example of the presentation history information 102 recorded and stored in the presentation history storage unit 51 (step S110).

  Here, when the user tries to change the way of searching for content, the process returns to step S101 via step S111.

  In step S101, the condition instructing unit 2 changes the content selection condition to “popularity = A” by the user and proceeds to step S102 to perform the second process.

  Then, the condition collating unit 31 collates with the condition instructing unit 2 whether or not the content selection condition “popularity = A” set again has been used in the past. This collation is performed via the condition designation presentation history extraction unit 52.

  The condition designation presentation history extraction unit 52 refers to the content selection condition-content list correspondence table 1011 (FIG. 4) in the presentation history information 101 stored in the presentation history storage unit 51, and adds content to the presentation history of the user USER-01. Confirm that there is no selection condition “popularity = A”.

  Then, the condition designation presentation history extraction unit 52 sends an empty set indicating that no condition has been found to the condition matching unit 31, and proceeds to step S103.

  In step S103, the content selection unit 32 selects the content of “popularity = A” from the content information 100 (FIG. 3) stored in the content storage unit 1. In this case, contents CONT-01, CONT-04, CONT-07, CONT-10, and CONT-11 are selected, and the selected contents are sent to the base sorting unit 33, and the process proceeds to step S104.

  In step S104, it is assumed that the base sorting unit 33 is defined as sorting in the dictionary order of titles, for example, as a base sorting method.

  In this case, the contents are CONT-01 (title = Alps girl), CONT-07 (title = Gots), CONT-10 (title = football legs vs Sakura), CONT-11 (professional baseball digest), CONT-04 ( Sorted in the order of demons. Then, the base sorting unit 33 sends the sorted content information to the correction sorting unit 34, and the process proceeds to step S105.

  In step S105, the correction sorting unit 34 extracts the content designation presentation history extraction unit for each content (CONT-01, CONT-07, CONT-10, CONT-11, CONT-04) sent from the base sorting unit 33. The presentation history is acquired via 53.

  In this case, the content designation presentation history extraction unit 53 refers to the content-history correspondence table 1022 (FIG. 6) of the presentation history information 102, and the content of the presentation history “CONT-01 is the number of presentations twice, the browsing history. Once, CONT-04 obtains a presentation history such as “the number of presentations is 0, the browsing history is 0”, and the process proceeds to step S106.

  In step S106, the correction sorting unit 34 refers to the presentation history of each content acquired via the content designation presentation history extraction unit 53, and corrects the sorting order using the presentation history for the content sorted by the base sorting unit 33. I do.

  In this correction, the content that has not been presented to the user is prioritized so that the content is placed at the top of the content list.

  Here, an example of the correction method performed by the correction sorting unit 34 is shown.

  The correction sorting unit 34 acquires the presentation history of USER-01 for each content to be presented via the content designation presentation history extraction unit 53 of the presentation history management unit 5.

  Here, CONT-01 = 2 times of presentation, CONT-07 = 0 times of presentation, CONT-10 = 0 times of presentation, CONT-11 = 0 times of presentation, and CONT-04 = 0 times of presentation are acquired. . Then, the obtained presentation history is sorted in ascending order (in ascending order), the presentation order of CONT-01 with two presentations is lowered, and CONT-07, CONT-10, CONT-11, CONT-04, CONT- Rearrange 01.

  Note that this correction sorting method is an example, and another method may be used to prioritize content that has not been presented to the user and place it at the top of the content list. Then, the process proceeds to step S107.

  In step S <b> 107, the result of sorting in the correction sorting unit 34 is stored in the presentation history storage unit 51. Here, the browsing history information 103 stored in the presentation history storage unit 51 is shown in FIG. 7 as an example. Then, the process proceeds to the second step S108.

  Here, the content list presentation unit 4 presents a content list. This content list is generated according to the order sent from the correction sorting unit 34.

  Further, the fact that the contents CONT-07, CONT-10, CONT-11, CONT-04, and CONT-01 are presented together is recorded in the presentation history of the presentation history storage unit 51.

  FIG. 8 shows a case where an example of presentation of this content list is displayed on an information presentation screen (not shown).

  In the example of FIG. 8 displayed on the information presentation screen (not shown), the selection condition is “popularity = A” and CONT-01 that has been presented to the user USER-01 in the past is listed. A content list is generated so that unpresented content that has been presented at the bottom and content that has not been browsed are presented at the top of the list.

  As described above, in the information presenting device according to the present invention, the contents are sorted based on the presentation history of the contents, and the contents that have been presented under another content selection condition are reduced in priority at the time of sorting, and the priorities of the unpresented contents are displayed. Can be increased.

By adopting this mechanism, the user can know different types of content by changing the selection method. Furthermore, from the viewpoint of the service provider, more content can be presented to the user, so that not only the best selling content but also so-called long tail products can be introduced to the user, and the user's access to the service can be activated. This has the effect of increasing the number of content users of the entire service.
[Variation in the first embodiment]
In the first embodiment of the present invention, the content list generation unit 3 that generates the content list may consider variations due to some configuration changes in the sorting method in which the content is sorted.

  Specifically, for example, as a variation of one configuration, a configuration in which the content list generation unit 3 does not include the base sorting unit 33 is also conceivable. Here, FIG. 9 shows a configuration diagram in which the base sorting unit 33 is not provided.

  In the case of the configuration shown in FIG. 9, the content selected by the content selection unit 32 is sent directly to the correction sorting unit 34, and the content is sorted by the correction sorting unit 34.

  In this case, the function of sorting the contents based on the presentation history of the contents, which is a feature of the present invention, is provided in the correction sorting unit 34. Therefore, even in the configuration shown in FIG. be able to.

  As another variation, in the first embodiment of the present invention, as the presentation history managed by the presentation history management unit 5, the last presentation date and time of each content is recorded together, and the content is corrected by the correction sorting unit 34. When sorting the content, it may be configured such that the content with the latest final presentation date / time is less likely to be presented, and the content with the oldest final presentation date / time is more easily presented than the content with the new final presentation date / time.

  By taking such a form, it becomes possible to present in order from the content with the lightest memory of the user in the next priority of the content that the user does not know at all.

  As another variation, in the first embodiment of the present invention, the presentation history managed by the presentation history management unit 5 is recorded according to the importance of each content for each user, and the correction sorting unit 34 When sorting content, a form in which content with high importance of content is more easily presented than content with low importance of content may be considered.

  Specifically, for example, when correction sorting is performed, content is scored in proportion to the presentation history, and sorting is performed in ascending order of content score. This variation is realized by providing a mechanism such as reducing the number according to the importance of the content.

  However, the content importance reflection method described here is merely an example, and the present invention is not limited to this, and other reflection methods may be used.

  The content importance input methods include a method in which the user explicitly inputs, a method in which the user's access history and preference information are automatically generated, and a method in which the importance of purchased content is extremely reduced. However, any method including other methods may be used.

  As another variation, in the first embodiment of the present invention, the correction sorting unit 34 performs correction so that content that has not been presented to the user is prioritized and placed higher in the content list. In this case, a configuration in which content that has been presented to the user is deleted from the content list is conceivable.

In this case, the amount of calculation is generally reduced by deleting content that exceeds a certain threshold as compared with the amount of calculation for sorting the content. Therefore, this variation applies the information presenting apparatus of the present invention particularly in a large-scale service. It becomes effective when.
[Example 2 of the first embodiment]
As a second example in the first embodiment, a second example will be described.
(4-2) Second Example In the second example, in a portal site or the like on the Internet, a content provider that provides content while holding the content right, and content provided by a plurality of content providers A secondary service that provides value-added services to the primary service provider and the primary service provider's content providing service that enables content search by integrating the attribute information of each content, etc. A case where a service is provided by a provider will be described.

  The primary service provider is assumed to be a service provider that provides a content providing service using conventional technology, and manages the content storage unit 1, the condition instruction unit 2, the content selection unit 32, and the base sorting unit 33, and arbitrarily selects them. The search keyword is selected and the contents are sorted according to popularity, price, dictionary, etc., and a list of contents is provided to the user.

  The secondary service provider provides an additional function to the content providing service provided by the primary service provider, and manages the condition matching unit 31, the correction sorting unit 34, the content list presentation unit 4, and the presentation history management unit 5. In consideration of situations such as content presentation history and user content selection history, for example, content that is not presented to the user is preferentially presented, and content is presented in the same order under the same content selection conditions. As such, it provides the added value of properly presenting content.

  From the user's point of view, by using the content providing service provided by the secondary service provider, it is possible to obtain higher convenience than the service provided by the primary service provider.

  Thus, it is considered that by providing a highly convenient service, the secondary service provider can obtain compensation from the user.

  From the point of view of the primary service provider, the content service channel is granted by permitting the use of content to secondary service providers for users who want to use highly convenient services even if they pay a fee. There is an advantage that can be expanded.

  In addition, a form in which the primary service provider does not provide the content providing service directly to the user but only provides the content to the secondary service provider is also conceivable.

In this case, from the secondary service provider, the primary service provider will do the work of collecting content from multiple content providers and unifying the attribute information of various types of content. Therefore, it is possible to maintain functions specialized for users.
(5) Other Embodiments (5-1) Second Embodiment FIG. 10 is a configuration diagram of an information presentation apparatus showing a second embodiment for carrying out the present invention.

  The information presentation apparatus according to the second embodiment is characterized by further including a correction sorting control unit 6 that controls whether the correction sorting unit 34 is operable in addition to the configuration of the first embodiment.

  The correction sorting control unit 6 sorts the content based on the function of the correction sorting unit 34, that is, the content presentation history, and the content that has been presented under another content selection condition is lowered in priority at the time of sorting. To control whether or not to activate the function of increasing the priority of

  FIG. 11 is a flowchart showing the operation of the second embodiment. In addition to the flowchart showing the operation of the first embodiment, the flowchart showing the operation of the second embodiment further includes step S112 for determining whether or not correction sorting is possible between step S104 and step S105. It is characterized by that.

  Here, the description of the same process in the same step is omitted, and the operation of the added step S112 will be described.

  In this step S112, it is determined whether or not correction sorting is performed according to the correction sorting control unit 6.

  If the correction sorting control unit 6 determines to perform correction sorting, the process proceeds to step S105.

  Then, as described in the explanation of the operation of the first embodiment after step S105, the correction sorting is performed, the contents are sorted based on the presentation history of the contents, and the contents that have been presented under the different content selection conditions are Decrease the priority when sorting and increase the priority of unpresented content.

  On the other hand, if the correction sorting control unit 6 determines not to perform correction sorting, the process proceeds to step S108.

  In step S108, the content list presentation unit 4 generates a content list and presents the content list in the arrangement order sorted according to the base sorting condition in step S104.

  Note that a user, a service provider, an information presentation device, and the like can be considered as the main body that inputs the correction sorting permission / inhibition to the correction sorting control unit 6.

  Here, a case where the user himself / herself can make correction sorting will be described.

  When searching for content, there are cases where the user wants to search for content based on a fixed index (base sorting method) while searching for content while looking for as much content as possible. .

  An example of a case where the user wants to search for content while analyzing the tendency of the content based on the determined index (base sorting method) includes a case where a survey is being performed. The former is also the case where the method of searching for the desired content is clearly determined, such as searching in order of popularity.

  In this way, when the user's purpose is in these cases, the user can realize his / her favorite searching method by explicitly inputting that correction correction is not performed through the correction sorting control method.

  On the other hand, if there is no way to search for the desired content as in the former case, it seems that this is the case where the user wants to search for a favorite content while viewing as much content as possible. In this case, the user can enter new contents as the operation is performed by inputting to perform correction sorting by the correction sorting control method.

  Next, a case where the information presentation apparatus itself inputs whether correction sorting is possible will be described.

  As a case where the information presenting apparatus itself inputs, it is conceivable to input whether or not correction sorting is possible based on the TAT (turn around time) of the information presenting apparatus and the machine load.

  For example, when the information presentation apparatus determines that the TAT of the information presentation apparatus is reduced due to concentration of access or the like, the correction sorting control unit 6 reduces the load on the information presentation apparatus and improves the TAT. Is input that no correction sorting is performed.

  Then, when TAT is improved, the correction sorting control unit 6 is instructed to perform correction sorting.

  By controlling in this way, it becomes possible to prevent the service quality of the information presentation apparatus from deteriorating.

  As described above, according to the second embodiment, in the information presentation apparatus according to the second embodiment, for example, when a user wants to sort and browse content by using an index with a purpose such as content analysis. In the conventional method, a list of contents is presented by a desired sorting method. On the other hand, when searching for contents while viewing as many contents as possible, various kinds of contents are added to the contents list by performing correction sorting. It can be presented.

  Further, as shown in the second embodiment, it is possible to determine whether or not to perform correction sorting in consideration of the processing load on the information presentation apparatus side.

That is, it is possible to control whether or not content sorting based on the content presentation history is performed in accordance with the situation of the user's judgment and the information presentation device side load.
(5-2) Third Embodiment FIG. 12 is a configuration diagram of an information presentation apparatus showing a third embodiment for carrying out the present invention.

In the information presentation device according to the third embodiment, in addition to the configuration of the first embodiment, the presentation history for correcting the presentation history information stored in the presentation history storage unit 51 in the presentation history management unit 5 A correction unit 54 is further provided.
[Example 1 of the third embodiment]
A third example of the third embodiment will be described.
(5-2-1) Third Example In the third example, the presentation history correction unit 54 passes a certain period of time since the last use of the presentation histories stored in the presentation history storage unit 51. Delete the presentation history.

  Therefore, by providing the presentation history correction unit 54, even the content once presented can be presented to the user again after a certain period (history deletion period).

  That is, even content that has been presented to the user once and has not been selected by the user is given the opportunity to be presented to the user again after the history deletion period.

  Although various patterns can be considered for this history deletion period depending on the application service, the length of the period is not particularly limited in the implementation of the present invention. For example, it is usually possible to set a period of 1 day (24 hours) to 1 week, but if the service provider wants to introduce as much content as possible to the user, the history deletion period is set to 1 It is also possible to set a long period such as a week or a month.

Note that this history deletion period can be set according to the method of setting all the history deletion periods, the method of setting the history deletion period for each content, the method of changing the history deletion period according to the season, or the number of days from the content registration date. Various methods such as a method of changing the deletion period are conceivable, and the present invention is not limited to these methods.
[Example 2 of the third embodiment]
The fourth example of the third embodiment will be described.
(5-2-2) Fourth Example In the fourth example, the presentation history correction unit 54, from the presentation history stored in the presentation history storage unit 51, according to the special intention of the service provider, Delete the presentation history for specific content.

  Therefore, by providing the presentation history correction unit 54, it is possible to easily present the content that the service provider wants to strongly recommend to the user even after the content has been presented once.

  That is, since the presentation history related to specific content can be deleted by the presentation history correction unit 54, the following service operation can be performed.

  For example, in a portal site on the Internet, the service provider that operates the portal is different from the content provider that manages the content provided on the portal, and the service provider takes content from multiple content providers and portals. There is a case of building a site.

  In this case, from the viewpoint of the content provider, in order to improve the sales of the content to be provided, it is a good idea to present it to the user as much as possible.

  Based on this, by receiving an additional fee from the content provider who wants to expose as much content as possible, the service provider explicitly deletes the presentation history for the content owned by the content provider, and the content provider Make it easy to present the contents of the provider.

Various methods such as a method of deleting all of the presentation histories at once and a method of deleting the presentation history in a period shorter than a normal deletion period can be considered. The service operation described above is only one example of the third embodiment, and the third embodiment is not limited to the fourth example.
[Example 3 of the third embodiment]
A fifth example of the third embodiment will be described.
(5-2-3) Fifth Example In the fifth example, the presentation history correction unit 54, from the presentation history stored in the presentation history storage unit 51, for the special intention of the service provider, Delete the presentation history related to specific content selection conditions. Alternatively, the presentation history correction unit 54 explicitly describes the presentation history intended by the service provider for the specific content selection condition.

  Specifically, for example, in a portal site on the Internet, there are cases where a service provider operating a portal arbitrarily controls the order of content presentation when searching for content using a certain search keyword.

In such a case, by providing the presentation history correction unit 54, the service provider can unconditionally delete the presentation history of the selection conditions so that the order in which the service provider intended the content is presented. The content list can be presented in the intended order.
[Example 4 of the third embodiment]
The sixth example of the third embodiment will be described.
(5-2-4) Sixth Example In the sixth example, the presentation history correction unit 54 is stored in the presentation history storage unit 51 according to the size of the presentation history stored in the presentation history storage unit 51. Delete the presentation history.

  Specifically, for example, when the size of the presentation history stored in the presentation history storage unit 51 exceeds a set threshold value, the information presentation device determines and deletes the presentation history.

  The threshold may be a case where the threshold is set for the entire information presenting apparatus or a case where the threshold is set for each user. However, any method including other methods may be used.

In addition, the method of determining the presentation history to be deleted may be a method of deleting from the old presentation history or a method of deleting from a less important presentation history, but also this method, including other methods, It may be a simple method.
[Example 5 of the third embodiment]
The fifth example of the third embodiment, which is the seventh example, will be described.
(5-2-5) Seventh Example In the seventh example, in a portal site on the Internet, a service provider that operates a portal, etc., and a content provider that manages content provided on the portal, However, the service provider will explain a case where a portal site is constructed by depositing content from a plurality of content providers.

  In this case, the service provider usually collects the value from the content provider by presenting the content owned by the content provider to the user, or the content provider or the user uses the content. Profit is gained by collecting consideration from the user.

  In the information presentation apparatus according to the seventh embodiment, when the service provider collects additional consideration from the content provider who desires to present more content to the user, the service provider passes the presentation history correction unit 54 to The presentation history stored in the presentation history storage unit 51 related to the content owned by the content provider is deleted.

As a result, in the seventh embodiment, it becomes possible to easily present the content of the content provider who has collected additional consideration to the user.
[Example 6 of the third embodiment]
An eighth example according to the sixth embodiment will be described.
(5-2-6) Eighth Example In the third example, in a portal site on the Internet, a service provider that operates a portal, etc., and a content provider that manages content provided on the portal, However, the service provider will explain a case where a portal site is constructed by depositing content from a plurality of content providers.

  In this case, the content provider pays the service provider when the content entrusted to the service provider is presented to the user, or pays the service provider when the user uses the content. By paying, the user can provide the owned content to the user.

  In the information presentation apparatus according to the eighth embodiment, when the content provider wants to present more content to the user, the content provider pays an additional fee to the service provider, thereby providing the information via the presentation history correction unit 54. The presentation history stored in the presentation history storage unit 51 related to the content owned by the content provider is deleted.

Thus, in the seventh embodiment, it is possible to make it easier for the user to present the owned content by paying additional consideration. The entity that instructs the presentation history correction unit 54 to delete the history may be either a service provider or a content provider.
