JP6944360B2 - Devices, methods, and programs that control the presentation order of content - Google Patents

Description

The present invention relates to a technique for controlling the presentation order of contents.

By accessing a network such as the Internet, the user terminal can acquire one or more contents distributed, posted, or published on the network and display them on the display screen of the user terminal. An example of "content" is article content such as news. Further, the display screen of the user terminal may be referred to as a "browsing screen".

Here, when displaying a plurality of contents on the browsing screen of the user terminal, there is known a technique of rearranging the display order according to the click through rate (CTR) for the contents.

The CTR represents the ratio of the number of times the content is clicked (the number of clicks) to the number of times the content is displayed on the browsing screen (number of impressions). Therefore, the "CTR" can be said to be an example of an index indicating the degree of interest of the user in the content.

However, for example, even if an article similar to an article viewed by the user on the display screen (for example, content having a high CTR) is updated, the update may not be reflected in the display order on the display screen of the terminal.

Therefore, even if an article similar to an article having a high CTR viewed once on the browsing screen is updated, the user may not view the update. That is, an article having a high CTR, in other words, an article having a high degree of interest (or topicality), may lose the viewing opportunity by the user.

One of the objects of the present invention is to increase the viewing rate of content having a high degree of interest or topicality.

The device that controls the presentation order of the content according to one aspect scores a score for each of the similar contents that are similar to each other among the plurality of contents delivered to the network, based on the click rate and the passage of time from the delivery. A calculation unit to be calculated, and a control unit that adds the scores of other similar contents to the scores of the latest similar contents among the similar contents and controls the presentation order of the similar contents based on the scores of the similar contents. And.

According to one aspect of the present invention, it is possible to increase the viewing rate of content having a high degree of interest or topicality.

It is a figure which shows the 3rd screen display example of the similar article list in the user terminal which concerns on one Embodiment. It is a figure which shows the 4th screen display example of the similar article list in the user terminal which concerns on one Embodiment. It is a block diagram which shows an example of the hardware configuration of the computer which concerns on one Embodiment.

Regarding the technology for rearranging the display order of contents, for example, the priority is given by weighting the degree of relevance (in other words, the degree of similarity) between the information provided to the user and the freshness of the provided information. Let us consider a technology that calculates and provides information in the order of calculated priority.

However, this technique can only give priority to either the similarity or the freshness of information. Even if a parameter called CTR, which is an example of an index of the degree of interest of the user, is additionally applied to such a "weighted sum", the alternative is only an alternative.

Alternatively, for example, even if an attempt is made to increase the weight of similarity or freshness as the CTR is higher, if the similarity weighted by the CTR is higher, even an old article has a higher priority. Also, if the freshness weighted by the CTR is new, even articles with low similarity will have a high priority.

Therefore, it is difficult to give priority to providing new articles to users among related articles with a high CTR, or in other words, similar articles with a high degree of interest (or topicality).

Therefore, in the following embodiment, the device, method, and / or program capable of preferentially displaying the latest content among similar content groups having a high degree of interest (or topicality), for example, on the display screen of the user terminal. explain. For convenience, such preferential display control may be referred to as "presentation order control" or "display order optimization" of the content. "Display" is an example of "presentation".

In "display order optimization", for example, the degree of interest (or topicality) and freshness are reflected for each content similar to each other based on the CTR of the content such as an article and the passage of time of the content. A process of calculating the score may be included.

In addition, "display order optimization" includes, for example, a process of adding the score of another similar content to the score of the latest content in the similar content group (which may be referred to as "merging"). good.

Then, in the "display order optimization", for example, the display order of the individual similar contents displayed on the user terminal (for example, displayed in a list format) is controlled (for example, rearranged) according to the score of each similar content group. ) Processing may be included. The "display order" may be paraphrased as the "display rank".

Further, the specific mode and / or layout of the display of the similar content group in the list format is not limited. For example, a plurality of similar contents are displayed side by side in a tile shape (or grid shape) on the display screen (viewing screen) 50 of the user terminal 5 as described later with reference to FIGS. 6 and 8 to 12. Alternatively, they may be displayed side by side in other aspects and / or layouts.

Hereinafter, an example of a device, a method, and a program for controlling or optimizing the display order of contents will be described with reference to the drawings. In the following, as the "content" whose display order is controlled, the content including the "article" will be described as an example. In addition, "content containing an article" may be abbreviated as "article content" or simply "article". Article content may include image data such as photographs and / or video.

(Configuration example of display order optimization device)
FIG. 1 is a block diagram showing a configuration example of a device 1 for controlling or optimizing the display order of contents (for example, articles) according to an embodiment. The device 1 may be referred to as a "display order optimization device 1".

The display order optimization device 1 is exemplified by an article collection unit 11, a similar article determination unit 12, an article data holding unit 13, an article CTR calculation unit 14, an article CTR holding unit 15, a score calculation unit 16, and a score holding unit 17. , The display order management unit 18 and the display result collection unit 19 may be provided.

The article collection unit 11 collects articles (data) published (may be referred to as "posting" or "distribution") on a network 3 such as the Internet. Article data may be distributed, for example, by one or more servers located in network 3.

Therefore, collecting article data by the article collecting unit 11 may include accessing one or more servers. Accessing the server may include, for example, accessing a DNS (Domain Name System) server. The term "delivery" may be paraphrased into other terms such as "public" or "published".

The article data collected by the article collecting unit 11 is stored in, for example, the article data holding unit 13. The collection range of articles may be predetermined. For example, the article collection unit 11 may access an IP (Internet Protocol) address corresponding to each domain name to collect articles based on a predetermined list of a plurality of domain names. The list of domain names is an example of setting information that defines the range of article collection sources (in other words, article distribution sources).

The similar article determination unit 12 performs similarity determination on, for example, the article group stored in the article data holding unit 13. The period of articles (which may also be referred to as a "time range") that are candidates for similarity determination may be determined for each article genre, such as politics, economy, entertainment, or gourmet.

For example, for a genre in which the freshness of an article (in other words, breaking news) is considered important, such as breaking news of sports results, a shorter time range may be set than in other genres. The method of similarity determination is not limited. Further, the target of the similarity determination may be the text of the article, the title of the article, or both the text and the title.

Further, the similar article determination unit 12 determines one representative article from the article group determined to be similar to each other (hereinafter, may be abbreviated as "similar article group") (even if it is referred to as "selection"). Good). The rules for selecting representative articles (which may be paraphrased as "conditions" or "policies") are not limited.

As a non-limiting example, representative articles may be selected in the order of (1) → (2) below.
(1) Articles with the latest article generation date and time from the same distribution source (2) Articles with the latest article generation date and time from other distribution sources

Figure 2 shows an example of selecting representative articles. FIG. 2 exemplifies three articles A, B, and C of the same distribution source, which are determined to be similar to each other. In the example of FIG. 2, since the generation date and time of the article A is the latest among the three articles A, B, and C, the similar article determination unit 12 selects the article A as the representative article.

In addition, for example, in the genre such as entertainment and / or gourmet, there may be a need for articles from other distributors, such as wanting to compare various articles, so representative articles are listed in the order of (2) → (1) above. It may be selected.

The "source" of an article may be identified by the domain name of the source of the article, as a non-limiting example. In addition, the "article generation date and time" may be treated as the same as the delivery date and time (or publication date and time) for convenience. If the delivery date and time (or publication date and time) can be specified in the collected article data, the delivery date and time (or publication date and time) may be used as a reference.

For example, the similar article determination unit 12 may specify the delivery date / time (or publication date / time) from the RSS (rich site summary) tag of the collected article data. When the delivery date and time cannot be specified, the similar article determination unit 12 may treat the date and time when the RSS tag is acquired as the delivery date and time (or the publication date and time).

The article data holding unit 13 holds the article data collected by the article collecting unit 11.

The article CTR calculation unit 14 calculates the CRT (clicks / impressions) based on, for example, the number of clicks and the number of impressions (imp) for the article aggregated by the display result totaling unit 19.

As described above, "CTR" represents the ratio of the number of times the content is clicked (the number of clicks) to the number of times the content is displayed on the browsing screen 50 (the number of impressions), and indicates the degree of interest of the user in the article. This is an example of the index shown. “Click” is an example of a user's selection operation on the browsing screen 50. Therefore, the "click count" by the user may be paraphrased as the "selection count" by the user. The calculated CRT may be stored in association with the article, for example, in the article CTR holding unit 15.

The "number of impressions" is not counted when the application used for viewing the article content on the user terminal 5 only acquires the article content. On the other hand, when the same article content is displayed a plurality of times on the same user terminal 5, it is counted in the "impression number". Therefore, the "number of impressions" may be treated as the number of views by the user.

Further, the application used for browsing the article content on the user terminal 5 may be abbreviated as "browsing application" or "terminal application" for convenience. The "browser" may be regarded as a kind of "browsing application".

The score calculation unit 16 calculates the score for all the articles for which a certain time has passed since they were displayed, and also determines the threshold value of the CTR. The calculated score may be stored in the score holding unit 17 in association with the article, for example.

For the calculation of the score, for example, a function in which the score changes (for example, decreases) with the passage of time may be used. In this case, the score reflects the freshness of the article (which may be referred to as the "trend") over time. Therefore, the score may be referred to as a "trend score" for convenience.

As a non-limiting example, a function that linearly decreases the score with the passage of time may be used for the calculation of the trend score, as shown by the solid line A in FIG. 3, and the dotted line B in FIG. As shown in, a function may be used in which the score decreases exponentially with the passage of time. In other words, the amount of change (decrease) in the trend score may be constant or may change with the passage of time.

Further, the score calculation unit 16 increases the trend score of articles whose CTR is equal to or higher than the threshold value by, for example, determining the threshold value of the CTR calculated by the article CTR calculation unit 14 for each article, and obtains the trend score of articles whose CTR is less than the threshold value. Decrease. For the CTR threshold value, for example, a common value may be set regardless of the genre of the article, or a different value may be set for each genre of the article.

The increase or decrease of the trend score according to the threshold value determination result of the CTR may be performed, for example, by adding or subtracting a specific value (a predetermined value or a variable value) to the trend score, or already. It may be performed by changing the amount of decrease of the above-mentioned function with the passage of time.

As a non-limiting example, FIG. 4 shows an example in which the trend score is increased or decreased with respect to the function shown by the solid line A in FIG. As illustrated in FIG. 3, the score calculation unit 16 may increase the trend score of a certain article after the timing when it is determined that the CTR of the article is equal to or higher than the threshold value. On the other hand, the score calculation unit 16 may reduce the trend score of the article after the timing when it is determined that the CTR of the article is less than the threshold value.

A common value may be set for the amount of increase and decrease of the trend score regardless of the genre of the article, or a different value may be set for each genre of the article.

The score holding unit 17 holds a calculated trend score for each similar article, for example.

The display order management unit 18 is an example of a “control unit” that controls the presentation order of each similar article based on the trend score of each similar article. However, all or part of the above-mentioned article collection unit 11, similar article judgment unit 12, article data holding unit 13, article CTR calculation unit 14, article CTR holding unit 15, and score holding unit 17 are managed in display order. A "control unit" may be formed together with the unit 18.

In other words, any of the functions of the display order management unit 18, the article collection unit 11, the similar article determination unit 12, the article data holding unit 13, the article CTR calculation unit 14, the article CTR holding unit 15, and the score holding unit 17. One or more functions may be integrated into a "control unit".

The display order management unit 18 adds, for example, the trend score of another similar article to the trend score of the representative article among the similar article group based on the trend score of each similar article stored in the score holding unit 17. ..

FIG. 5 shows an example of adding the trend score by the display order management unit 18. FIG. 5 shows an example in which the trend score of the article A selected as the representative article is “3” and the trend scores of the similar articles B and C are “2” and “1”, respectively.

In the example of FIG. 5, the display order management unit 18 adds the trend score of the representative article A = 3, the trend score of the similar article B = 2, and the trend score of the similar article C = 2. As a result, the trend score of the representative article A becomes 3 + 2 + 1 = 6. Therefore, the trend scores of Article A, Article B, and Article C are "6", "2", and "1", respectively.

In this way, by adding the trend score of other similar articles to the trend score of the representative article in the similar article group, the trend score of the latest article in the similar article group has a high degree of interest or topicality. It is "raised" according to the trend (in other words, the excitement). Therefore, for example, the priority order of the representative article can be appropriately set according to the degree of interest or the degree of topicality, as compared with the case of adding a predetermined value to the trend score of the representative article.

Then, the display order management unit 18 controls the display order of the similar article group displayed in a list format on the browsing screen 50 of the user terminal 5 based on the trend score of each similar article. For example, the display order management unit 18 sorts similar articles in descending order of the trend score.

FIG. 6 shows an example in which a plurality of similar articles A to F provided in a list format to the user terminal 5 are sorted in descending order of their respective trend scores. However, the display order management unit 18 may sort similar articles in ascending order of the trend score. Further, the display order management unit 18 may sort similar articles according to other rules regarding the trend score, which are different from the descending order and the ascending order.

The display order between similar articles (for example, articles B and C) having the same trend score may be the same order, or may be determined to be different order according to some rule. Further, when presenting a similar article group in a list format, sorting the similar pseudo-group according to the trend score may be regarded as presenting the similar pseudo-group in a ranking format ranked by the trend score.

The display result totaling unit 19 acquires information (for example, a log) related to the browsing history from the terminal application used for browsing the article content on the user terminal 5, for example. Information on the browsing history may be acquired from a plurality of user terminals 5.

In addition, the display result aggregation unit 19 aggregates the acquired browsing history information, and acquires, for example, the number of impressions and the number of clicks used in the calculation of CTR for each article content.

The user terminal 5 can access the display order optimization device 1 via, for example, a wireless or wired access network. Therefore, the information regarding the browsing history may be provided to the display order optimization device 1 from the user terminal 5 via the access network, for example. Further, information such as a list of similar articles addressed to the user terminal 5 may be provided from the display order optimization device 1 to the user terminal 5 via the access network.

(Operation example)
Hereinafter, an operation example of the display order optimization device 1 described above will be described with reference to the flowchart of FIG. 7.

The article collecting unit 11 collects articles published (or posted) on the network 3, and stores the collected articles in, for example, the article data holding unit 13 (step S11).

The similar article determination unit 12 performs similarity determination on the article group stored in the article data holding unit 13 (step S12), and as described in FIG. 2, the article group determined to be similar to each other (similar articles). One representative article is determined in the group) (step S13).

On the other hand, the CTR calculation unit 14 calculates the CTR for each similar article based on the aggregation result by the display result aggregation unit 19, associates the calculated CTR with the corresponding similar article, and stores the calculated CTR in, for example, the article CTR holding unit 15. (Step S14).

The score calculation unit 16 calculates the trend score and determines the CTR threshold value for all similar articles for which a certain time has passed since they were displayed, as described in FIGS. 3 and 4, for example. S15 and S16).

As a result of the threshold value determination, the score calculation unit 16 increases the trend score for similar articles whose CTR is equal to or higher than the threshold value (YES in step S16) (step S17). On the other hand, for similar articles whose CTR is less than the threshold value (NO in step S16), the score calculation unit 16 reduces the trend score (step S18).

Next, the display order management unit 18 adds the trend scores of other similar articles to the trend scores of the representative articles in the similar article group, as described in FIG. 5 for example (step S19).

Then, as shown in FIG. 6, the display order management unit 18 sorts the display order of the similar article group in the descending order of each trend score (step S20), and lists the sorted similar article group, for example. Output to the user terminal 5 in the format (step S21). Similar articles are displayed on the display screen 50 of the user terminal 5 by, for example, a terminal application.

The display order optimization device 1 periodically repeats the processes of steps S11 to S21 illustrated in FIG. 7 (for example, every few minutes to several tens of minutes). The cycle of repetition may be set to a different cycle for each genre of articles. For example, for a genre that has a need for breaking news, such as breaking news of sports results, a shorter cycle may be set than for other genres.

As described above, according to the above-described embodiment, the display order of the latest articles (for example, the latest articles having a common topic) similar to the articles having a high degree of interest or topicality whose CTR is equal to or higher than the threshold value can be increased. In other words, the latest article of an article having a high degree of interest or topicality can be displayed on the browsing screen 50 of the user terminal 5 at a position (prominent position) that is more noticeable than other articles.

Therefore, it is possible to give an incentive for browsing to both users who have not browsed articles with a high degree of interest or topicality and users who have browsed articles in the past. Therefore, it is possible to suppress the loss of browsing opportunities even though the article has a high degree of interest or topicality, which contributes to an increase in the article browsing rate and, in turn, promotion of usage.

(Screen display example of similar articles)
Next, a screen display example of a similar article group (similar article list) on the user terminal 5 will be described with reference to FIGS. 8 to 12. Note that FIGS. 8 to 12 show a screen display example of an article list including six similar articles as a non-limiting example.

(First screen display example)
FIG. 8 is a diagram showing a first screen display example of a similar article list. In FIG. 8, as a non-limiting example, among a plurality of similar articles A to F displayed in a list format on the display screen 50 of the user terminal 5, tags are added to articles A to C having a CTR equal to or higher than the threshold value. An example is shown.

For example, articles A to C may be tagged with information indicating that the article has a high degree of interest or topicality, such as "commonly seen". The tag may be added by, for example, the display management unit 18 (the same applies hereinafter). The information indicating that the article has a high degree of interest or topicality may be explicit information or implicit information.

By attaching such a tag to similar articles whose CTR is above the threshold value, the latest articles of articles with a high degree of interest or topicality can be displayed in a position that is easily noticed by the user, and in addition, the degree of interest or topicality can be displayed. You can make it easier for users to pay attention to expensive articles.

Therefore, it is possible to give the user an incentive to browse articles with a high degree of interest or topicality, and for example, it is possible to further increase the browsing rate of articles with a high degree of interest or topicality.

(Second screen display example)
9 and 10 are diagrams showing a second screen display example of a similar article list. As a non-limiting example, FIG. 9 shows an example in which tags are added to articles A to D that have been replaced with representative articles among a plurality of similar articles A to F. As a non-limiting example, FIG. 10 shows an example in which articles A and B that have been replaced with representative articles are tagged among a plurality of similar articles A to F. The screen display example of FIG. 10 may be regarded as a modification of the screen display example of FIG.

For example, when the similar article selected as the representative article in step S13 of FIG. 7 is replaced with another similar article, the display order management unit 18 newly selects the similar article as the representative article (in other words, after the replacement). Add a tag to the representative article).

For example, the display order management unit 18 indicates that a similar article newly selected as a representative article has "replaced" or "updated" to an article (representative article) having a high degree of interest or topicality. A tag including the above may be added. The "information indicating that there has been an update" may be explicit information or implicit information.

The "information indicating that there was an update" indicates the timing of the "update", such as "there was an update within XX hours (or within YY minutes)", for example, as shown in FIG. Time information may be included. Further, as shown in FIG. 10, for example, information without time information such as "attention" and / or "latest" may be included in "information indicating that there has been an update".

When there are a plurality of similar articles that have been replaced with the representative articles, the display order management unit 18 determines the articles to be tagged according to a predetermined rule (for example, threshold determination of the trend score). good.

By tagging as illustrated in FIGS. 9 and 10, in addition to being able to display articles with a high degree of interest or topicality in a position that is easily visible to the user, articles with a high degree of interest or topicality have been updated. It can be made easier for the user to notice.

Therefore, it is possible to give the user an incentive to browse articles with a high degree of interest or topicality, and for example, it is possible to further increase the browsing rate of articles with a high degree of interest or topicality.

(Third screen display example)
FIG. 11 is a diagram showing a third screen display example of a similar article list. In FIG. 11, as a non-limiting example, among a plurality of similar articles A to F, the representative articles are replaced, and the articles A and B whose distribution sources are the same before and after the replacement are tagged. An example is shown.

The fact that the representative article has been replaced and the distribution source of the article is the same before and after the replacement means that the representative article has been updated and the updated article is continuous information from the article before the update (in other words). , Follow-up). Whether or not the article distribution source is the same before and after the update (replacement) may be identified based on, for example, the domain name indicating the article distribution source.

Therefore, for example, if the similar article selected as the representative article in step S13 of FIG. 7 is replaced with another similar article and the distribution source is the same domain name before and after the replacement, the display order management unit 18 will post the replacement. Add a tag to the representative article of.

For example, the display order management unit 18 attaches a tag including information indicating that there is "continuous" information (follow-up report) from before the replacement to the representative article of the same distribution source after the replacement, as shown in FIG. You can do it. The "information indicating that there is continuous information" may be explicit information or implicit information.

The "information indicating that there is continuous information" includes time information such as "follow-up information from XX hours ago (or YY minutes ago)", as in the second screen display example described above. It may be.

By tagging as illustrated in FIG. 11, in addition to being able to display articles with a high degree of interest or topicality in a position that is easily visible to the user, the user can be informed that there was a follow-up report on the article with a high degree of interest or topicality. Can be noticed.

Therefore, it is possible to give the user an incentive to browse articles with a high degree of interest or topicality, and for example, it is possible to further increase the browsing rate of articles with a high degree of interest or topicality.

(Fourth screen display example)
FIG. 12 is a diagram showing a fourth screen display example of a similar article list. As a non-limiting example, FIG. 12 shows an example in which similar articles A to F are displayed side by side in chronological order according to their respective delivery times.

For example, in step S20 of FIG. 7, the display order management unit 18 sorts a plurality of similar articles in descending order of trend score and in order of newest delivery date and time. Further, the display order management unit 18 may attach a tag indicating time information according to the delivery date and time to each of the similar articles. For example, as shown in FIG. 12, the display order management unit 18 may attach a tag including information indicating how many minutes or hours before the current time to each of the similar articles.

With such tagging, in addition to being able to display articles with a high degree of interest or topic in a position that is easily visible to the user, the freshness of the articles with a high degree of interest or topic is intuitive to the user at a glance. It will be easier to understand.

Therefore, it is possible to give the user an incentive to browse articles with a high degree of interest or topicality, and for example, it is possible to further increase the browsing rate of articles with a high degree of interest or topicality.

(Supplementary information about tags)
The above-mentioned "tag" may be referred to by another name such as "mark" or "label". In addition, the "tag" may be highlighted for the article to be given. Highlighting may include, for example, making the color, shape, and / or font of the tag different from the article. In addition, the position where the tag is attached may be a position where the correspondence with the article can be visually recognized, for example, a position near the article, or a part or all of the tag to the extent that it does not interfere with the viewing of the article. May overlap the article.

(Summary of effects of the embodiment)
According to the above-described embodiment, the score is calculated based on the click rate and the passage of time for each of a plurality of similar articles having a CTR equal to or higher than the threshold value and having a high degree of interest or topicality, and is the latest among the similar articles. Add the scores of other similar articles to the scores of the representative articles of.

As a result, the trend score of the latest article among similar articles is "raised" according to the degree of interest or topicality (in other words, excitement). Therefore, for example, rather than adding a predetermined value to the score of the latest article, the priority order of the representative article can be appropriately set according to the degree of interest or the degree of topicality.

Then, by controlling the presentation order of each similar article based on the score of each similar article, for example, the display order of the latest article (for example, the latest article having a common topic) in the similar article group. Can be raised. In other words, the latest article of an article having a high degree of interest or topicality can be displayed on the browsing screen 50 of the user terminal 5 at a position that is more noticeable than other articles.

Therefore, it is possible to give an incentive for browsing to both users who have not browsed articles with a high degree of interest or topicality and users who have browsed articles in the past. Therefore, it is possible to suppress the loss of browsing opportunities even though the article has a high degree of interest or topicality, which contributes to an increase in the article browsing rate and, in turn, promotion of usage.

In addition, in the score calculation of each similar article, the score of the content whose CTR is above the threshold is increased, and the score of the content whose CTR is below the threshold is decreased. The higher the display order, the higher the display order. Therefore, the above-mentioned effects can be achieved by simple score control.

The increase and decrease of the score can be realized, for example, by changing the degree of decrease of the function whose score decreases with the passage of time. In this case, a more flexible or more flexible setting can be made with respect to the control of the display order as compared with a simple fixed amount reduction of the score (in other words, a linear reduction).

In addition, in selecting representative articles, by prioritizing articles from the same distribution source over articles from different distribution sources, for example, the display order of the latest follow-up reports by the same distribution source for articles with a high degree of interest or topicality can be determined. Can be enhanced over articles from different sources.
