Description

Information processing apparatus, information processing method, program, and storage medium

The present invention relates to a technical field regarding an information processing apparatus, an information processing method, a program, and a storage medium. Specifically, the present invention relates to various processes for presenting recipes to the user.

JP 2013-178831 A

When a plurality of pieces of information are presented to the user, a ranking is often given to the plurality of pieces of information based on an index indicating whether the information is useful (or the user is searching for) information, and the information is often presented according to the ranking. For example, when presenting a search result for a search query specified by a user, the degree of coincidence with the search query and the number of browsing by other users (in other words, how much of a plurality of search results presented as search results Based on information such as whether the user has selected and browsed, presentation priority is assigned to each search result and presented to the user.
Patent Document 1 describes that the order of information presentation is determined by comparing the ranking information of keywords associated with each piece of information to be provided.

However, it is not always optimal to present a plurality of pieces of information in order based on priority information (rank information) determined before presenting to the user. For example, from the user's behavior with respect to the information that the user has already browsed, there is no appropriate information to be presented later in the information waiting to be browsed by the user whose presentation order has already been determined. For example. In such a case, it may be difficult to satisfy the user only by presenting the information group whose presentation order has already been determined to the user according to the presentation order.

Therefore, an object of the present invention is to present appropriate information to the user according to the user's information browsing.

An information processing apparatus according to the present invention includes a content acquisition unit that acquires a plurality of contents as condition conforming content based on a predetermined condition, a presentation priority setting unit that sets a presentation priority for the condition conforming content, and content browsing An interest level calculation unit that calculates an interest level obtained by quantifying the user's interest in accordance with the content acquisition unit, wherein the content acquisition unit additionally acquires the condition-adapted content according to the interest level. A second acquisition process for acquiring content of interest different from the condition-adapted content, and the presentation priority setting unit presents the content of interest earlier than at least a part of the acquired condition-adapted content. Thus, the presentation priority is reset.
When a plurality of contents are presented in order, once the presentation priority of the contents is determined once, the determined presentation priority is not often changed. Therefore, even when the user's interest changes in the process of presenting the acquired content according to the presentation priority or when the user's interest can be newly grasped, the determined presentation priority is optimized ( It is difficult to say that the content is highly convenient for the user.
Therefore, the user's interest (interest) is measured in the process of presenting the content, and is expressed as a degree of interest.
Then, the content of interest newly acquired based on the interest level has a higher presentation priority than at least a part of content (standby content) that has been acquired and has not been presented to the user (that is, The presentation priority is reset (so that it is inserted before the unpresented conditional-conforming content). Therefore, the presentation priority that can follow the change in the user's interest is set as appropriate.

In the information processing apparatus described above, the degree of interest may be calculated for the category to which the content belongs.
Thereby, when the user shows an interest in one content, the degree of interest in the category to which the content belongs is calculated high.

In the information processing apparatus described above, the degree of interest may be calculated for content.
Accordingly, the content of interest corresponding to the specific information for each content is extracted and presented to the user.

The interest level calculation unit of the information processing apparatus described above may calculate the interest level according to the browsing of the content of interest.
As a result, the degree of interest is further calculated for the content of interest extracted according to the degree of interest of the user with respect to the condition-adapted content. Then, based on the degree of interest in the content of interest, the content of interest is further acquired and presented.

The information processing apparatus described above further includes a common point extraction unit that extracts a common point of the calculated content with a high degree of interest, and the content acquisition unit performs the content of interest based on the common point in the second acquisition process. May be obtained.
In many cases, a user is not only interested in one content (or one category) but also interested in a plurality of contents (or a plurality of categories). In such a case, in view of the interest in one content A, the interested content A1, A2,... Related to the content A is presented, and then in view of the interest in the content B that the user has shown interest in, In this case, even if the content of interest B1, B2,... Related to the content B is presented, the user can be satisfied to some extent, but it may be difficult to present the content of interest with a high degree of satisfaction.
Therefore, the common points of the content having a high degree of interest calculated so far are extracted, the content of interest is acquired based on the common points, and presented to the user.

The presentation priority setting unit of the information processing apparatus described above may perform the resetting so that the content of interest is presented immediately after the content being browsed by the user.
Thereby, when the user performs an operation of displaying the next content, the content of interest is presented immediately after the content being browsed. In other words, the content of interest added before presenting the waiting content among the condition-matching content is presented with the highest priority.

The content acquisition unit of the information processing apparatus described above may perform the second acquisition process when an interest level greater than the maximum value of the interest level calculated in a series of browsing sessions is calculated.
A series of browsing sessions is various processes (communications) exchanged in a series of periods, for example, from connection to a server for browsing content until connection is released.
It is not preferable that the content of interest continues to increase as standby content because it increases the amount of communication of the user. In such a case, in this configuration, the second acquisition process is executed only when the interest level larger than the maximum value is calculated, so that the second acquisition process is executed. Is suppressed.

The interest level calculation unit of the information processing apparatus described above may not use the browsing time in a state where a plurality of contents are presented to the user when the interest level is calculated based on the browsing time of the content. Good.
Thereby, the interest level can be calculated by a relatively light process of measuring the browsing time.

The degree-of-interest calculation unit of the information processing apparatus described above may calculate the degree of interest based on a browsing time with respect to an information amount of content.
When content with a large amount of information and content with a small amount of information coexist, it is inevitable that the viewing time of content with a large amount of information will be long. Therefore, the degree of interest is calculated based on the browsing time in consideration of the content information amount.

In the information processing apparatus described above, the first acquisition process is executed in response to the number of acquired and unviewed contents being less than a threshold value, and the threshold value is determined according to a content browsing speed. You may set for every user.
The browsing speed is different for each user. The threshold is provided for designating the timing for starting the acquisition of the next condition-conforming content so that the user does not have to wait for the content acquisition.
Therefore, it is considered that a threshold value should be provided in consideration of different browsing speeds for each user.

In the information processing apparatus described above, when the presentation that allows browsing of a plurality of contents at a time is possible, the presentation priority setting unit is configured to be presented between the contents being presented in the resetting. The presentation priority for the content of interest may be set.
That is, the content of interest that is acquired based on the user's interest is presented between the plurality of content being browsed.

The information processing method according to the present invention includes a content acquisition step of acquiring a plurality of contents as condition conforming content based on a predetermined condition, a presentation priority setting step of setting a presentation priority for the condition conforming content, and the condition conforming A first acquisition step of additionally acquiring content, an interest level calculating step of calculating an interest level obtained by quantifying the user's interest according to browsing of the content, and an interest different from the condition-adapted content according to the interest level A second acquisition step of acquiring content, and a step of resetting the presentation priority so that the content of interest is presented earlier than at least a part of the acquired condition-adapted content.
This information processing method provides an environment in which appropriate information is presented to the user according to the user's information browsing.

The program according to the present invention is a program that causes an information processing apparatus to execute processing executed as the information processing method. The above information processing apparatus is realized by these programs.
A storage medium according to the present invention is a storage medium storing the above program.

According to the present invention, appropriate information can be presented to the user according to the user's information browsing.

<1. Overall configuration>

First, the overall configuration in the embodiment of the present invention will be described.
In the following description, a cooking recipe (hereinafter simply referred to as a recipe) will be described as an example of information (content) presented to the user.
One content means one recipe, and one recipe includes information such as cooking procedures, ingredients used, and cooking utensils.
And the recipe management server 1 is mentioned as an example as an information processing apparatus which provides a user with information (recipe).
Furthermore, a recipe site operated (managed) by the recipe management server 1 is taken as an example of a portal site for providing a service capable of searching for a recipe or posting a recipe according to a search query designated by a user.

An overall configuration including a recipe management server 1 as an information processing apparatus of the present invention is shown in FIG.
The recipe management server 1 is connected to the user terminals 3, 3, 3,. The recipe management server 1 also includes a user DB (Database) 50 in which information about users is stored, a recipe DB 51 in which information on recipes is stored, a search DB 52 in which information on search queries and search results is stored, and a recipe site. Connected to a web page DB 53 in which web page data of various web pages to be stored is stored.
In the recipe management server 1, the user terminals 3, 3, 3... And each DB constitute a network system via the communication network 2.

The recipe management server 1 executes a search process for searching for a recipe according to a search query designated by the user. The search query is an example of a “predetermined condition” in the claims.
Moreover, the process which transmits the recipe group extracted as a search result to the user terminal 3 is performed. In the following description, the recipe extracted according to the search query designated by the user is referred to as “condition-matching recipe”. A condition-matching recipe is a specific example of “condition-matching content” in the claims.

When presenting a condition-adapted recipe to the user, a predetermined number (for example, 20) of condition-adapted recipes are not sent to the user terminal 3 all at once. Send the recipe first. Then, in response to the number of unviewed recipes (unviewed condition-adjusted recipes already transmitted) being less than the threshold while the user is proceeding with browsing a predetermined number of condition-adapted recipes A predetermined number of condition-adapted recipes to be presented next are acquired from the extracted condition-adapted recipes and transmitted to the user terminal 3. In the following description, the threshold is referred to as “additional acquisition threshold”.
A specific example will be described. The recipe management server 1 transmits 20 items selected from 1000 condition conforming recipes to the user terminal 3. Then, 980 unacknowledged condition-matching recipes are sent in response to the fact that the number of condition-matching recipes that have been transmitted and have not been browsed is less than 5 as the additional acquisition threshold in the process of browsing the 20 condition-matching recipes. Select 20 new messages from and send them. By transmitting a predetermined number of recipes as appropriate from the condition-matching recipe as a search result, unnecessary communication amount can be reduced.
In the following description, a transmitted and unviewed recipe is described as a “standby recipe”. For example, when there are 20 recipes that have been transmitted and 15 recipes (recipes displayed on the screen of the user terminal 3) viewed by the user, there are 5 standby recipes.
The standby recipe is an example of “standby content” in the claims.

In addition, the recipe management server 1 performs a process for managing recipe information and a process for managing user information. Further, as a process for presenting appropriate information (recipe) to the user, a process for calculating the user's interest level with respect to the recipe or the cooking category is performed.
A specific configuration will be described later.

The configuration of the communication network 2 is not particularly limited. For example, the Internet, an intranet, an extranet, a LAN (Local Area Network), a CATV (Community Antenna TeleVision) communication network, a virtual private network (Virtual Private Network), a telephone line A network, a mobile communication network, a satellite communication network, etc. are assumed.
Various examples of transmission media constituting all or part of the communication network 2 are also envisaged. For example, IEEE (Institute of Electrical and Electronics Engineers) 1394, USB (Universal Serial Bus), power line carrier, telephone line, etc., infrared such as IrDA (Infrared Data Association), Bluetooth (registered trademark), 802.11 wireless It can also be used wirelessly, such as mobile phone networks, satellite lines, and digital terrestrial networks.

The user terminal 3 is a terminal used by a user who posts a recipe to the recipe management server 1 and a user who searches and browses recipe information managed by the recipe management server 1.
In the user terminal 3, various transmission / reception processes and display processes are executed as necessary. The user terminal 3 is, for example, a PC (Personal Computer), a feature phone, a PDA (Personal Digital Assistant) having a communication function, or a smart device such as a smartphone or a tablet terminal.

<2. Hardware configuration>

FIG. 2 is a diagram illustrating hardware of the recipe management server 1 and the user terminal 3 shown in FIG. 1, and hardware of the user DB 50, the recipe DB 51, the search DB 52, and the web page DB 53. A CPU (Central Processing Unit) 101 of a computer device in each server, terminal, or DB is loaded into a RAM (Random Access Memory) 103 from a program stored in a ROM (Read Only Memory) 102 or a storage unit 108. Various processes are executed according to the program. The RAM 103 also appropriately stores data necessary for the CPU 101 to execute various processes.

The CPU 101, ROM 102, and RAM 103 are connected to each other via a bus 104. An input / output interface 105 is also connected to the bus 104.
The input / output interface 105 includes an input unit 106 including a keyboard, a mouse, and a touch panel, a display including an LCD (Liquid Crystal Display), a CRT (Cathode Ray Tube) and an organic EL (Electroluminescence) panel, and an output including a speaker. A storage unit 108 configured by a unit 107, a HDD (Hard Disk Drive), a flash memory device, and the like, and a communication unit 109 that performs communication processing and communication between devices via the communication network 2 are connected.

A media drive 110 is also connected to the input / output interface 105 as necessary, and a removable medium 111 such as a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory is appropriately mounted, and information can be written to the removable medium 111. Reading is performed.

In such a computer apparatus, data and programs can be uploaded and downloaded through communication by the communication unit 109, and data and programs can be transferred via the removable medium 111.
The CPU 101 performs processing operations based on various programs, whereby information processing and communication described later are executed in each of the recipe management server 1, the user terminal 3, the user DB 50, the recipe DB 51, the search DB 52, and the web page DB 53.

In addition, each information processing apparatus which comprises the recipe management server 1, the user terminal 3, the user DB50, the recipe DB51, the search DB52, and the web page DB53 is not limited to a single computer apparatus as shown in FIG. Instead, it may be configured by a plurality of systemized computer devices. The plurality of computer devices may be systemized by a LAN or the like, or may be arranged in a remote place in a communicable state using a VPN (Virtual Private Network) using the Internet or the like. The plurality of information processing apparatuses may include an information processing apparatus as a server group (cloud) that can be used by the cloud computing service.

Note that the recipe management server 1, the user terminal 3, the user DB 50, the recipe DB 51, the search DB 52, and the web page DB 53 do not have to include all the above-described configurations (such as the CPU 101). For example, the user DB 50 may not include the input device 106, the output device 107, the media drive 110, and the like.

<3. Functional configuration>

As shown in FIG. 3, the recipe management server 1 includes a recipe management unit 1a, a user management unit 1b, a recipe acquisition unit 1c, a presentation priority setting unit 1d, an interest level calculation unit 1e, a common point extraction unit 1f, and a transmission control unit. 1g.

The recipe management unit 1a manages the recipe information posted by the user (information associated with the recipe title, the used ingredients, the cooking method, the cooking category information to which the recipe belongs, etc.) in the recipe DB 51. For example, a recipe of “vegetable curry” posted by a user is a recipe that belongs to the cooking category “curry”. , “Spinach”, seasonings (such as “salt” and “pepper”), and the like (for example, “carrero”) are associated and stored.

Also, the recipe management unit 1a manages a creation report posted for each recipe. The creation report is a report that describes the deliciousness and ease of cooking felt for other recipes when other users actually cook using the posted recipes. The creation report is associated with each recipe in the recipe DB 51 and managed.

The user management unit 1b performs various processes in order to manage information on users who use various services provided by the recipe management server 1.
For example, management is performed by associating a user ID that can uniquely identify a user with a name, age, gender, and contact information (such as a telephone number and an e-mail address) and storing them in the user DB 50. Moreover, the process which acquires user information from user DB50 is performed.

The recipe acquisition unit 1c performs a search process according to the search query, and extracts a condition-matching recipe as a search result. And the recipe acquisition part 1c performs the process which acquires a part from the extracted condition adaptation recipe. Specifically, a predetermined number of recipes (for example, 20 as described above) are acquired from the extracted condition-conforming recipes. The process of acquiring a predetermined number of recipes from the condition-matching recipe is referred to as “first acquisition process”. The first acquisition process is executed each time a recipe is browsed on the user terminal 3 and the number of standby content items is less than the additional acquisition threshold.

Moreover, the recipe acquisition part 1c performs the process which acquires the recipe which seems to be a user's interest as an interested recipe from the user's behavior with respect to the shown recipe. Specifically, a recipe is searched based on the degree of interest for each recipe estimated from the user's behavior, and the extracted search result is acquired as an interest recipe. In the following description, the process of acquiring a recipe based on the interest estimated from the user's behavior is referred to as “second acquisition process”.
The interest recipe is an example of “interesting content” in the claims.
The recipe acquisition unit 1c is a specific example of a “content acquisition unit” in the claims.

The presentation priority setting unit 1d sets the presentation priority for each recipe as content presented to the user.
The presentation priority of the condition-matching recipe is calculated based on the degree of matching with the search query designated by the user, the degree of popularity of the recipe, and the like.
In addition, the interest recipe presentation priority is calculated based on the interest level described below, the popularity level of the recipe, and the like.

The interest level calculation unit 1e calculates an interest level obtained by quantifying the user's level of interest based on the user's behavior with respect to the recipe.
The degree of interest may be given for each recipe, or may be given for each cooking category to which the recipe belongs. In the following description, both examples will be described.

The common point extraction unit 1f performs a process of extracting common points between recipes. Specifically, common points between recipes to which an interest level equal to or higher than a predetermined value is extracted. That is, as a pre-process for searching for a recipe that the user is likely to be interested in, elements common to the recipe that the user is interested in are extracted. Elements are extracted as keywords, for example.

The transmission control unit 1 g performs a process of transmitting the extracted recipe or the acquired recipe to the user terminal 3.
For example, web page data generated by including recipe information to be presented to the user is transmitted to the user terminal 3. In addition, when the recipe management server 1 receives a request for additional acquisition of a recipe to be displayed on the web page data, after executing various processes, information on the additional recipe is transmitted to the user terminal 3.
In addition, transmission of recipe information (or transmission of web page data including recipe information) is performed based on presentation priority information given to each recipe information.

As web page data, URL (Uniform Resource Locator) information of a web page and arrangement information of objects (parts such as images, texts, and banners) arranged on each web page are stored. The arrangement information is information that describes the arrangement mode (position, size, color, etc.) of each object on the web page.

An example of web page data displayed on the user terminal 3 is shown in FIG.
FIG. 4 is an example of a search result presentation page in which a recipe (condition-matching recipe) corresponding to a search query designated by the user is presented as a search result.
The search result presentation page can be viewed using the web browser 4 operating on the user terminal 3.

The web browser 4 is provided with a web page display field 5, and various operators (buttons and input fields) 6, 6, 6.
A web page display field 5 on which a search result presentation page is displayed includes a search query input field 7 for performing a search and a search button 8 for transmitting a search request to the recipe management server 1 and a recipe group as a search result. Is displayed. The web browser 4 may be configured so that recipes are displayed one by one in the web page display field 5.
One piece of recipe information includes, for example, image information indicating a completed drawing of the recipe, text information indicating ingredients, cooking procedures, and the like.

The recipes displayed in the web page display field 5 include those that have already been displayed and those that are not. In the following description, for the sake of convenience of explanation, what has been displayed (that is, what is estimated to have been browsed by the user) will be referred to as a browsing recipe 9, and what has not yet been displayed will be referred to as a standby recipe 10. However, the browsing recipe 9 and the standby recipe 10 are distinguished for explanation, but there is actually no change such as a change in status.
4, recipes that can be browsed among recipes presented as search results are displayed as browse recipes 9, 9, 9,. The user performs a scroll operation (hereinafter referred to as a feed operation) for moving the recipe information upward in order to view an unviewed recipe. Further, in order to browse again the recipe that has already been browsed and has disappeared upward in the web page display field 5, a scroll operation (hereinafter referred to as a return operation) for moving the recipe information downward is performed.
Further, as shown in FIGS. 5A and 5B, recipes that the user has not browsed yet are arranged as standby recipes 10, 10, 10... Below the browsing recipes 9, 9, 9. . Although the standby recipe 10 is not actually arranged below the browsing recipe 9, it can be understood that it is virtually arranged in an invisible state, so such an expression is used. . The same applies to the following description.

As shown in FIG. 4, among the four recipes displayed in the web page display field 5, three are in a state where all information can be browsed and are referred to as browsing recipes 9, 9, 9. The remaining one is in a state where a part of the recipe information can be browsed.
As for a recipe that only a part of the recipe information can be browsed, a part of the recipe information can be browsed, so it may be a browsing recipe 9 as shown in FIG. 5A, and not all information can be browsed. As shown in FIG. 5B, the standby recipe 10 may be used. When a recipe that allows only part of the recipe information to be viewed is the standby recipe 10, the recipe changes from the standby recipe 10 to the browsed recipe 9 when the user can browse all of the recipe information.
Further, when the recipe information once browsed by the user's return operation (that is, the browse recipe 9) is moved below the web page display column 5, even if it is at the position of the standby recipe 10, it has already been browsed. Since it is a recipe, it becomes the browsing recipe 9.

In addition, the recipe management server 1 is provided with various units necessary for realizing a function for transmitting and receiving various types of information and an authentication process for a user login operation. The authentication process is a process of collating the user ID (Identification) and the login password as login information transmitted from the user terminal 3 with the authentication information stored in the user DB 50.

Each function as the recipe management server 1 is a function realized by processing executed by the CPU 101 in the information processing apparatus according to the program. However, all or some of the processes described below may be realized by hardware.

Further, when each function is realized by software, each function need not be realized by an independent program. Processing of a plurality of functions may be executed by one program, or one function may be realized by cooperation of a plurality of program modules.
Each function may be distributed among a plurality of information processing apparatuses. Furthermore, one of the functions may be realized by a plurality of information processing apparatuses.

<4. DB>

Each DB managed by the recipe management server 1 will be described. Each DB shown below may be realized in any form as long as the recipe management server 1 is accessible. For example, all the DBs may be formed in the storage unit in the same system as the recipe management server 1, or a part or all of each DB may be separated, or a computer system such as a remote place May be provided. Of course, each DB does not need to be formed in one device (for example, one HDD). Each DB does not need to be configured as a single DB. For example, information stored as the user DB 50 may be stored and managed by a plurality of user DBs (for example, a login user DB and a transaction user DB). Each DB described below is merely an example of a storage unit for information related to the processing of the embodiment in the form of one DB.

[4-1. User DB]
The user DB 50 stores information on users who receive services provided by the recipe management server 1. For example, personal information such as a login password, name, age, sex, and mail address is stored in association with one user ID (Identification) that can identify one user.

In addition, the user DB 50 may store preference information for each user. The preference information is the user's favorite ingredients (favorable ingredients) or disliked ingredients (non-favorable ingredients) determined by the recipe management server 1 according to the user's behavior. The preference information is used when the user performs a recipe search.
In each example described below, user information is used to infer the user's interest (interest) for the recipe. The user information for estimating the interest is the browsing speed on the web page, and the information is stored in the user DB 50.
Further, when the above-described additional acquisition threshold is a numerical value corresponding to the browsing speed for each user, the threshold is also stored in the user DB 50.

[4-2. Recipe DB]
The recipe DB 51 is a DB that stores recipe information posted by the user. Specifically, for each recipe ID that can identify each recipe, a user ID that identifies the user who posted the recipe, post date information, cooking category information to which the recipe belongs, and ingredients used in the recipe (amount) Etc.), recipe recipes, image information such as cooking images (finished cooking images and cooking images), and other users who actually used the recipe (created dishes) A creation report ID that identifies the created creation report is associated with and stored.

Furthermore, each recipe ID is associated with information on the procedure outline content indicating the outline of the cooking procedure of the recipe.

In addition, URL (Uniform Resource Locator) information of a recipe detail page may be associated with the recipe ID and stored.
Further, the recipe DB 51 stores information on creation reports posted for each recipe. As the information of the created report, text information indicating the report content, a user ID that can identify the poster, posting date information, and the like are stored.

[4-3. Search DB]
The search DB 52 is a DB that stores search results corresponding to the search query. Specifically, multiple recipes are linked and stored as search results according to a search query such as a dish name such as “curry” or “hamburg” or an ingredient name such as “mushroom” or “tomato”. .
In order not to execute the search process each time according to the user's search operation, the search process using the search query is periodically executed in advance, and the search result extracted as a result is linked to the search keyword. And stored in the search DB 52.

[4-4. Web page DB]
The web page DB 53 stores data of various web pages that the recipe management server 1 provides to the user. Specifically, it is web page data such as a recipe search page, a special feature page, a search result presentation page, a recipe detail page, and a user page.
The information stored in the web page DB 53 may be stored in a structured document file such as HTML (Hyper Text Markup Language) or XHTML (Extensible HyperText Markup Language).

<5. Flow of processing>

[5-1. Overall flow]
First, an example of the flow of various processes performed between the user terminal 3 and the recipe management server 1 will be described with reference to FIG.
In response to the user performing an operation for displaying a login screen using the user terminal 3, the user terminal 3 executes a request process for login screen information (that is, web page data for displaying the login screen) in step S101. To do.

When a login screen information request is transmitted from the user terminal 3 to the recipe management server 1 by the login screen information request process, the recipe management server 1 executes a login screen information transmission process in step S201.
Thereby, for example, a web page corresponding to the login screen information (web page data) of the recipe site received from the recipe management server 1 is displayed on the user terminal 3.

Next, in step S102, the user terminal 3 executes login information transmission processing for transmitting login information (user ID and login password) according to the user input operation to the recipe management server 1.

When the login information is transmitted from the user terminal 3 to the recipe management server 1, the recipe management server 1 executes an authentication process in step S202, and executes an authentication result notification process in step S203.
Specifically, the recipe management server 1 compares the user ID and password input on the user terminal 3 with information stored in the user DB 50 to determine whether the user can log in, and authenticates the login permission information. As a result, the user terminal 3 is notified. In addition, while transmitting an authentication result to the user terminal 3, you may transmit the web page data of the top page of a recipe site. Thereby, user authentication is performed and the top page of the recipe site is displayed on the user terminal 3.

Note that a series of flows shown in FIG. 6 shows a case where it is determined that login is possible in the authentication processing in step S202. If it is determined in step S202 that login is not possible, the user terminal 3 executes the process of step S102 again, and the recipe management server 1 executes the process of step S202 accordingly.

The user who has successfully logged in then enters a search query to search for the recipe he is looking for. In response, the user terminal 3 executes a search query transmission process in step S103.

In step S204, the recipe management server 1 executes a search process using a search query. Thereby, the recipe group according to the search query designated by the user is extracted as a search result. As an example, an example in which 1000 recipes are searched as search results will be described. In the subsequent processing, specific examples will be described as appropriate.

Subsequently, in step S205, the recipe management server 1 performs a process of setting a presentation priority for 1000 recipes extracted as search results. As the presentation priority, a higher value is assigned to a recipe suitable for presentation to the user. For example, consider a search query specified by the user. Specifically, if the user specifies “chicken” as part of the search query, the recipe that uses “chicken” as the non-main ingredient has a higher presentation priority than the recipe that uses it as the main ingredient. May be.
Moreover, it can be based on the user's favorite food. A higher presentation priority may be set for a recipe that uses more of the user's favorite ingredients as used ingredients. In addition, the information of a favorite food material and a non-taste food material is memorize | stored in user DB50.
In addition, recipes that use seasonal ingredients according to the season may be set to a higher presentation priority, or recipes that have a higher number of views from other users or submissions of created reports have a higher presentation priority. May be set, or a higher presentation priority may be set for a recipe having a larger number of browsing in the most recent predetermined time (predetermined period). Of course, the presentation priority may be set considering these factors in combination, or the presentation priority may be set by other factors. Here, only an example is described.

In the subsequent step S206, the recipe management server 1 that has set the presentation priority for each recipe acquires a predetermined number (for example, 20) of recipes in descending order of the presentation priority from the extracted 1000 recipes, and as a search result. A process of transmitting to the user terminal 3 is executed.
Thereby, 20 pieces of recipe information are transmitted to the user terminal 3, and at least a part (for example, 3) of recipes are presented (displayed) on the web browser 4. In other words, of the 20 recipes received by the user terminal 3, 3 are the browsing recipes 9 and 17 are the standby recipes 10. Note that when the user performs a scroll operation and browses the recipes one after another, the number of browsing recipes 9 increases and the number of standby recipes 10 decreases.

Subsequently, in response to the user performing an operation indicating interest (interest) with respect to any one of the browsing recipes 9, the user terminal 3 executes processing for transmitting interest information in step S <b> 104. .
The interest information transmitted to the recipe management server 1 includes at least information for identifying a target recipe (for example, recipe ID) and information for identifying an operation type (that is, what operation has been performed as an operation indicating interest). It is.

Here, some specific examples of operations indicating interest (hereinafter, interest operations) are shown.
(1) Recipe detail page browsing operation (2) Favorite registration operation (3) Printing operation (4) Highlight operation (5) Click operation (6) Predetermined browsing time elapses

The recipe as a search result presented on the user terminal 3 is presented with an outline of the recipe as shown in FIGS. Therefore, when the user actually tries to use (cook) a recipe that the user is interested in, the recipe detail page is often browsed to browse the cooking procedure.
Therefore, an operation for browsing the recipe detail page is an interest operation.

In addition, a recipe that is considered to be browsed again later is highly likely to be registered as a favorite recipe so that it is not necessary to perform a search operation again.
Therefore, the favorite registration operation is also regarded as an interest operation.

And the printing operation of the recipe detail page is very likely to be performed when actually thinking about using the recipe. The printing operation is also an interest operation.

Furthermore, it is highly likely that an operation for highlighting text information related to a recipe (an operation for selecting a part of text) is performed while browsing the information on the recipe. Since it can be said that browsing the text is an interest in the recipe, the highlight operation is an interest operation.

Of the web page display field 5 of the web browser 4, the portion where the recipe information is displayed (the click operation on the region of the browsing recipe 9 in FIG. 4 may also be performed while browsing the information on the recipe). Therefore, the click operation is also an interest operation.
In addition, not only when a page transition occurs due to a user's click operation, but also when the user terminal 3 does not perform any processing (that is, nothing happens when clicked), it is regarded as an interest operation. The

Moreover, when the time which browses a recipe passes predetermined time (predetermined browsing time), it can be said that interest with respect to the said recipe is high. The elapse of the predetermined browsing time may be determined without the user performing an operation using an input device such as a mouse, but is defined as an interest operation for convenience.
Note that the user may leave the user terminal 3 while displaying the browsing recipe 9. In this case, there is a possibility that a predetermined browsing time elapses while the same browsing recipe 9 is continuously displayed on the screen of the user terminal 3, and it is determined that the recipe is interested. In order to avoid this, it is in a state where the user can browse the browsing recipe 9 displayed on the user terminal 3 by determining whether the user operates the mouse or the keyboard (for example, the cursor is moving). It may be determined whether or not. In addition, when a plurality of software programs including the web browser 4 are operating on the user terminal 3 (however, something that is displayed on the screen), the web browser 4 on which the browsing recipe 9 is displayed is displayed. The presence / absence of the operation of interest may be determined based on whether or not it is in an active state.
By determining whether or not the user has actually browsed the recipe, it is possible to grasp an appropriate browsing time, and accordingly, it is possible to appropriately estimate the presence and degree of interest.

Interest information is transmitted to the recipe management server 1 each time the user performs each interest operation described above.
For example, when the user browses the recipe detail page and performs a print operation, the interest information based on the interest operation of (1) is transmitted to the recipe management server 1 according to the browsing of the recipe detail page, and the subsequent print operation is performed. The interest information based on the interest operation (3) is transmitted to the recipe management server 1.

Returning to the description of FIG.
The recipe management server 1 that has received interest information indicating what interest operation has been performed on which recipe executes a process of calculating an interest level in step S207.
The interest level calculation process is a process for calculating the interest level for the browsing recipe 9 and is executed each time the interest information is received. A specific example will be described later.

After calculating the interest level, the recipe management server 1 executes a second acquisition process in step S208. As described above, the second acquisition process is a process of acquiring an interest recipe in which the user's interest is estimated. Specific examples will be described later.

Then, the recipe management server 1 performs the process which sets a presentation priority to the acquired interested recipe in step S209. The presentation priority of the interested recipe set here is set to a value higher than a part of recipes that have already been transmitted to the user terminal 3.
And the recipe management server 1 performs the transmission control process which transmits the information which tied the interested recipe and the presentation priority to the user terminal 3 in step S210.
This will be specifically described with reference to FIG.
In the state shown in FIG. 7, a part of the condition conforming recipes 11, 11... And the interested recipes 12, 12,. It is arranged below. In the standby recipes 10, 10,..., The recipes of interest 12, 12,. In other words, the interest recipes 11, 11,... Acquired by the second acquisition process are set to the highest presentation priority among the standby recipes 10, 10,.
Therefore, when the user performs a scroll operation (feed operation), the standby recipe 10 as the interested recipe 12 can be browsed first.

Returning to the description of FIG.
The user may perform a scroll operation in order to browse the standby recipe 10 in the process of browsing the condition-adapted recipe or the interest recipe transmitted to the user terminal 3.
In response to the user's scroll operation, the user terminal 3 accepts the scroll operation in step S105. For example, by accepting a scroll operation that is a feed operation, some standby recipes 10 are presented as browsing recipes 9 in the web page display field 5 of the web browser 4.
As browsing of the standby recipe 10 progresses (that is, when the standby recipe 10 changes to the browsing recipe 9), the number of standby recipes 10 decreases. Then, in response to the number of standby recipes 10 becoming less than the additional acquisition threshold (for example, 5), the user terminal 3 executes a process of transmitting a recipe addition request to the recipe management server 1.

In step S211, the recipe management server 1 that has received the recipe addition request confirms whether there is an unsent condition-matching recipe. In this example, since only 20 out of 1000 condition conforming recipes have been sent, there are 980 untransmitted recipes.
Therefore, in step S212, the recipe management server 1 acquires 20 of the 980 unsent condition-matching recipes based on the presentation priority.
Subsequently, the recipe management server 1 executes a process of transmitting the acquired 20 condition-matching recipes to the user terminal 3 in step S213.
Thereby, in the user terminal 3, 20 standby recipes 10 waiting for user browsing are added.

The flow of a series of processes shown in FIG. 6 is merely an example, and the flow of the same process is not necessarily the same.

[5-2. Recipe management server processing]
An example of the flow of processing executed by the recipe management server 1 to realize the above overall flow will be described with reference to FIG.

The recipe management server 1 receives various types of information from the user terminal 3 and executes corresponding processes. Therefore, the recipe management server 1 executes a monitoring loop process for monitoring whether various types of information have been received.
Specifically, as shown in FIG. 8, by repeatedly executing the processes of steps S301, S311, S321, and S331, whether or not login information is received, whether or not a search query is received, whether or not a recipe addition request is received, and interest information Monitors whether or not it is received. If it is determined that any information has been received, the corresponding processing is executed.

For example, the recipe management server 1 that has confirmed whether or not the login information has been received in step S301 executes the processes in steps S302 and S303 only when it is determined that the login information has been received.
That is, the recipe management server 1 executes a process of checking the login information input by the user with the authentication information stored in the user DB 50 in step S302, and in the subsequent step S303, notifies the user terminal 3 of the authentication result. Execute.
After the process of step S303, the recipe management server 1 returns to the monitoring loop process again.

In addition, the recipe management server 1 that has determined that the search query has been received in step S311 acquires a condition-matching recipe as a search result by executing a search process according to the search query in step S312, and in the subsequent step S313, the condition Processing to set the presentation priority for each conforming recipe is performed.
The condition-matching recipe includes a recipe that attracts the user's interest, and a recipe that does not attract the user's interest so much. It is desirable that the recipe management server 1 sets a higher presentation priority for a recipe that attracts the user's interest. For this reason, the recipe management server 1 may calculate the presentation priority using information specific to the user (for example, preference information or possessed cooking utensil information).

Then, in step S314, the recipe management server 1 executes a process of transmitting a part of the condition-adapted recipe (20 in the previous example) to the user terminal 3.
After the process of step S314, the recipe management server 1 returns to the monitoring loop process again.
If there are few condition-adapted recipes, it is also conceivable to transmit all condition-adapted recipes extracted as search results in the process of step S314.

Furthermore, the recipe management server 1 that has received the recipe addition request in step S321 executes a process of determining whether or not there is an unsent condition-matching recipe in step S322. As described above, this process is executed in response to the standby recipe being less than the additional acquisition threshold in the user terminal 3.
If there is an unsent condition-matching recipe, the recipe management server 1 executes a first acquisition process for acquiring a predetermined number of recipes from the unsent condition-matching recipe in step S323. However, if the number of unsent condition-matching recipes is less than the predetermined number, all unsent condition-matching recipes are acquired.
Subsequently, in step S324, the recipe management server 1 executes a process of transmitting a predetermined number (or all remaining) condition-matching recipes to the user terminal 3.
After the process of step S324, the recipe management server 1 returns to the monitoring loop process again.

Moreover, the recipe management server 1 which received the interest information in step S331 performs the process which calculates an interest degree in step S332.
Two examples of the interest level calculation processing will be described with reference to FIGS.

~ 5-2-1. First example of interest calculation processing
In the first example of interest level calculation processing (FIG. 9), the recipe management server 1 specifies a recipe (target recipe) that is a target of interest level calculation in step S401, and specifies an operation type of the interested operation in step S402. Execute the process.
The information on the target recipe and the information on the operation type of the operation of interest are transmitted from the user terminal 3 in step S104 of FIG. 6, for example. The operation type is a print operation, a highlight operation, or the like as described above.

Subsequently, in step S403, the recipe management server 1 calculates a degree of interest and executes a process that is given to the target recipe. As for the degree of interest, the calculated degree of interest may be given as it is, or a value obtained by adding the degree of interest calculated this time to the degree of interest given so far may be given again.
Note that the interest level calculated according to the type of interest operation performed by the user may be changed. For example, an operation such as the above-described (1) (recipe detail page browsing operation) or an operation (2) (favorite registration operation) in which strong interest in the recipe is estimated is calculated with a high degree of interest. May be. In addition, the operation (click operation) as described in (5) above may be calculated with a low interest level.

~ 5-2-2. Second example of interest calculation processing
Next, a second example (FIG. 10) of the interest level calculation process will be described.
The recipe management server 1 identifies the target recipe in step S501, and identifies the cooking category to which the target recipe belongs in step S502 as the target category.
The process in step S501 is the same as the process in step S401.

In step S502, the largest cooking category may be set as the target category, and the smallest cooking category may be set as the target category. For example, the cooking category “Curry” includes a cooking category “Indian curry” and a cooking category “Japanese curry” as subordinate categories. Under the cooking category “Indian curry”, the cooking category “Kima Curry” and the cooking category “Mutton Curry” belong. The recipe “My Home Keema Curry” is a recipe belonging to the cooking category “Curry”, a recipe belonging to the cooking category “Indian Curry”, and a recipe belonging to the cooking category “Kema Curry”.
Therefore, the target category may be the cooking category “curry”, the cooking category “Indian curry”, or the cooking category “Kemah curry”.
In addition, when the number of interested recipes is too large when acquiring the recipe of interest described later, it is desirable to set the lower-level cooking category as the target category, and conversely, when the number of interested recipes is too small, It is desirable that the cooking category is the target category.

The recipe management server 1 that has identified the target category identifies the operation type of the operation of interest in step S503 (same as step S402). Subsequently, in step S504, the recipe management server 1 performs a process of calculating the degree of interest and assigning it to the target category.

Returning to the description of FIG.
The recipe management server 1 that has calculated the degree of interest executes the second acquisition process in the subsequent step S333.
Here, three examples of the second acquisition process will be described.

5-2-3. First example of the second acquisition process
In the first example (FIG. 11) of the second acquisition process, a second acquisition process (that is, a process of acquiring an interest recipe) based on a recipe having an interest level equal to or greater than a predetermined value is executed.
In step S601, the recipe management server 1 determines whether there is a recipe in which the interest level set in the interest level calculation process (step S332) performed immediately before is newly equal to or greater than a predetermined value.

In a case where there is a recipe whose interest level newly becomes a predetermined value or more in the immediately preceding step S332, the recipe management server 1 in step S602, interests based on the recipe (that is, a recipe whose interest level newly becomes a predetermined value or more). Execute the process to get the recipe.
For example, the user who browsed the recipe searches for and acquires other recipes that are likely to be browsed or recipes registered in favorites.
In addition, recipes having common keywords such as ingredients, cooking methods, and cooking utensils included in the recipe are retrieved and acquired.

The recipe acquired by the second acquisition process may be a condition-adapted recipe that has already been extracted based on the user's search query.
For example, the condition-adapted recipe acquired in step S312 of FIG. 8 includes recipe A and recipe B, and the recipe A presentation priority is first and the recipe B presentation priority is 900. The recipe B is presented to the user considerably later, and the possibility that the user actually browses is low.
However, when the recipe B is acquired as an interest recipe in step S602 in FIG. 11, the recipe B can be regarded as a recipe that is likely to be of interest to the user. And the presentation priority higher than 900th is set by the process mentioned later, and the recipe B is shown to a user.

5-2-4. Second example of the second acquisition process
Next, a second example (FIG. 12) of the second acquisition process will be described.
In the second example of the second acquisition process, the interested recipe is acquired based on the common points of the highly interested recipe.
First, in step S701, the recipe management server 1 acquires a recipe whose interest level has reached a predetermined value or more. This process is a process performed based on the interest level set after the user last specified a search query. When the user specifies another search query again, the interest level set in the recipe is It is reset (that is, there are no recipes whose interest level is equal to or higher than a predetermined value).
However, when a plurality of search operations with different search queries are close to the latest time zone, the interest level need not be reset.

Subsequently, in step S702, the recipe management server 1 executes a process for extracting common points between recipes. Common points between recipes are, for example, ingredients used, utensils, cooking methods, and the like, and can be obtained, for example, by text analysis of recipe information. Of course, these pieces of information may be managed in association with recipes in advance as keywords. When the association management is performed in advance as a keyword, it is not necessary to analyze the text information, so that the processing load can be reduced.

Next, in step S703, the recipe management server 1 performs a search process using a keyword based on the common points, and acquires a recipe of interest.

5-2-5. Third example of second acquisition process
Next, a third example (FIG. 13) of the second acquisition process will be described.
In step S801, the recipe management server 1 acquires the maximum value of the degree of interest calculated in the same session.
Here, the same session will be described.
When the user uses the service of the recipe management server 1 by using the user terminal 3, the session is the same as long as the user performs some operation continuously (or without any operation time longer than a predetermined time). . For example, after searching for a recipe, when searching for a recipe again one day later, the sessions are different from each other.
Alternatively, an operation for browsing a plurality of recipes presented in response to a single search operation may be set as the same session. In this case, when a recipe search is performed using different keywords, the session is determined as another session. The same session at this time can be rephrased as a series of browsing sessions.

The recipe management server 1 that has acquired the maximum value of the interest level in the same session determines whether or not the interest level assigned in the interest level calculation process (step S332) performed immediately before has updated the maximum value in the subsequent step S802. To do.
When the maximum value of the interest level is updated, the recipe management server 1 executes a process of storing the updated maximum value of the interest level in step S803.
And the recipe management server 1 acquires the interest recipe according to the recipe to which the updated interest level was provided in step S804.
The interest recipe may be acquired based on keywords such as ingredients, cooking methods, and cooking utensils included in the recipe information to which the degree of interest set to the maximum value is given as in the first example of the second acquisition process. Then, as in the second example of the second acquisition process, it may be acquired based on common points extracted from a plurality of recipes (for example, the top three of the recipes with a high degree of interest).

Returning to the description of FIG.
The recipe management server 1 that has calculated the interest level calculated based on the user's interest operation and has acquired the interest recipe based on the interest level presents the priority setting process for setting the priority of the interested recipe in subsequent step S334. Execute.
In the presentation priority setting process for the interested recipe, for example, as shown in FIG. 7, the interested recipes 12, 12,... The presentation priority is set as follows.
In step S335, the recipe management server 1 that has set the presentation priority executes transmission control processing. In this process, information on the recipe of interest and information on the assigned presentation priority are transmitted to the user terminal 3. On the user terminal 3, a display based on the presentation priority is made.
After the process of step S335, the recipe management server 1 returns to the monitoring loop process again.

Note that the processing of steps S301, S311, S321, and S331 as the monitoring loop processing shown in FIG. 8 is merely an example, and other than this, whether or not a web page data request is received, whether or not there is a user information change request, or the like The process for confirming the above may be included in the monitoring loop process.

Here, two other examples of the presentation priority setting process for the recipe of interest other than those described with reference to FIG. 7 will be described.

5-2-6. First example of presentation priority setting process for a recipe of interest
In the first example of the presentation priority setting process for the recipe of interest (FIGS. 14 and 15), the presentation priority is set so that the recipe of interest 12 is displayed between the displayed recipes.
FIG. 14 shows a state before the transmission control process in step S335 (FIG. 8) is performed. That is, the condition conforming recipes 11, 11,... With the presentation priorities 121, 92, 84, 81, 74, 67, 66,. Has been. In addition, the recipe with a higher presentation priority value is preferentially presented to the user.

FIG. 15 shows a state after the transmission control process in step S335 (FIG. 8) is performed. In other words, the presentation priority = 91, 90, 89, 88,... Is set for the interested recipes 12, 12,. = 84 is arranged so as to be inserted between the condition-matching recipes 11.
In other words, the presentation priority of the interested recipes 12, 12,... Is arranged between the recipe with presentation priority = 92 and the recipe with presentation priority = 84 displayed in the web page display field 5. Thus, the presentation priority is set (step S334 in FIG. 8).

5-2-7. Second example of the presentation priority setting process for a recipe of interest
Next, a second example (FIGS. 14 and 16) of the presentation priority setting process for the recipe of interest will be described.
In the second example of the presentation priority setting process for the recipe of interest, a new presentation priority is also set for a recipe that has already been transmitted to the user terminal 3.
The description of the state (FIG. 14) before the transmission control process in step S335 (FIG. 8) is omitted.
FIG. 16 shows a state after the transmission control process in step S335 (FIG. 8) is performed. A new presentation priority is also set for a recipe that has already been transmitted to the user terminal 3 like the condition-matching recipe 11 in which the presentation priority shown in FIG. 16 is updated as 81 → 90.
The condition-adapted recipe 11 whose presentation priority is updated as 81 → 90 is rearranged above the condition-adapted recipe 11 whose presentation priority is 84. That is, the rearrangement according to the new presentation priority is also performed on the recipe that has already been transmitted to the user terminal 3 and viewed by the user in the order based on the new presentation priority.

In the presentation priority setting process for the recipe of interest in step S335 (FIG. 8), the presentation priority may be reset including the browsing recipes 9, 9,.
In that case, the browsing recipes 9, 9,... May be rearranged based on the new presentation priority, or may not be re-performed.
When the browsing recipes 9, 9,... Are rearranged based on the new presentation priority, the browsing recipes 9, 9,... Already displayed on the web page display field 5 are rearranged. May change. As a result, a recipe meaningful to the user is conspicuous and the user's eyes can be drawn.
Further, when the browsing recipes 9, 9,... Are not rearranged based on the new presentation priority, the user is looking for browsing the browsing recipes 9 that have already been browsed by a return operation. It is not lost where the browsing recipe 9 is arranged by rearrangement.

[5-3. First example of interest information based on browsing time]
As described above, the user terminal 3 transmits various types of interest information according to user operations. The interest information transmission process performed by the user terminal 3 is executed by, for example, a program attached to the web page data transmitted from the recipe management server 1 to the user terminal 3. In other words, a program is added to the web page data so that the user terminal 3 transmits the interest information based on various conditions.
When dedicated application software is executed on the user terminal 3, a program that defines various processing contents executed by the user terminal 3 may be incorporated in the application software.

Here, an example will be described as to what condition the interest information based on the browsing time (interest information transmitted when the above-described (6) is satisfied) is transmitted.
In the first example, the browsing time in a state where the number of recipes displayed in the web page display field 5 is plural is not used for determining whether or not to transmit the interest information.
Specifically, since it is unclear which recipe is being viewed no matter how much the user's viewing time increases in the state shown in FIG. 7 or FIGS. Interest information based on time is not sent.
On the other hand, as shown in FIG. 17, in the state where only one recipe is displayed in the web page display column 5, the browsing time is measured and the interest information based on the browsing time is transmitted as necessary.

[5-4. Second example of interest information based on browsing time]
A second example of what conditions the interest information based on the browsing time is transmitted will be described.
In the second example, when the user terminal 3 transmits the interest information based on the browsing time by the program attached to the web page data, it is based on the information amount (amount) of the recipe.
FIG. 18 shows the flow of processing to be executed by the user terminal 3 by the program attached to the web page data.
In step S901, the user terminal 3 executes a process of specifying a recipe to be browsed.
Subsequently, in step S902, the user terminal 3 specifies the amount of recipe information. The information amount of the recipe is, for example, the number of characters or the number of images of text information included in the recipe information, and is information used for estimating how long it takes to browse.

Subsequently, in step S903, the user terminal 3 performs processing for setting a predetermined browsing time. The predetermined browsing time set here is a threshold for determining whether or not to transmit interest information. That is, the predetermined browsing time is set according to the amount of recipe information acquired in the previous process.
After setting the predetermined browsing time, the recipe management server 1 determines in step S904 whether the browsing time for the target recipe has exceeded the predetermined browsing time.
If the predetermined viewing time has been exceeded (elapsed), the user terminal 3 executes processing for transmitting interest information based on the viewing time in step S905.

On the other hand, when it is determined that the predetermined browsing time has not been exceeded, the user terminal 3 determines in step S906 whether there is no change in the browsing target (that is, whether the user has started browsing other recipes).
When it is determined that the user has browsed another recipe (the recipe to be browsed has changed), the user terminal 3 executes the process of step S901 again.
Moreover, when the browsing object recipe is the same, the user terminal 3 performs the process of step S904 and S906 continuously.

In addition, although the example which performs each process shown in FIG. 18 by the user terminal 3 was given here, the recipe management server 1 may perform a part of process instead.
For example, the user terminal 3 may periodically execute the process of step S905 after executing the process of step S901.
On the other hand, the recipe management server 1 that has received the interest information performs the processing of steps S902 and S903 from the information for specifying the browsing target received from the user terminal 3, thereby specifying the information amount of the browsing target recipe and the predetermined browsing time. The setting is performed, and the process of determining whether or not the predetermined browsing time in step S904 has elapsed has been executed.
And when the predetermined browsing time has passed, the recipe management server 1 transmits an interest recipe to the user terminal 3 by performing the process of step S332 thru | or S335 of FIG.

<6. Modification>

[6-1. First Modification]
A modification of the series of processes in FIG. 8 executed by the recipe management server 1 will be described with reference to FIG.
In this modification, an example in which the first acquisition process is performed according to the browsing speed for each user will be described.
The recipe management server 1 confirms whether or not login information has been received, whether or not a search query has been received, whether or not standby recipe number information has been received, and whether or not interest information has been received, in a continuously executed monitoring loop process.

As shown in FIG. 19, steps S301 to S303, steps S311 to S314, and steps S331 to S335 are the same as the steps shown in FIG.
Therefore, here, the processing when the recipe management server 1 receives the number of standby recipes in step S321 ′ will be mainly described.
The user terminal 3 is configured to transmit information on the number of standby recipes to the recipe management server 1. The information on the number of standby recipes may be transmitted when the number of standby recipes changes, or may be transmitted every certain time (for example, every second).

In step S325, the recipe management server 1 that has received the standby recipe number information in step S321 ′ acquires an additional acquisition threshold corresponding to the user. The information about the additional acquisition threshold is stored in the user DB 50, for example.
The additional acquisition threshold is set according to the viewing speed of the user. That is, it is desirable to set the additional acquisition threshold value high for users with a high browsing speed and set the additional acquisition threshold value low for a user with a low browsing speed.

Subsequently, in Step S256, the recipe management server 1 determines whether or not the number of standby recipes received from the user terminal 3 is less than the additional acquisition threshold value. If it is not less than the additional acquisition threshold, the recipe management server 1 returns to the monitoring loop process without executing the first acquisition process.
On the other hand, if it is less than the additional acquisition threshold value, the recipe management server 1 executes the first acquisition process of step S323 after confirming whether or not there is an unsent condition-matching recipe in step S322.
Each process of steps S322 to S324 is the same process as each process described with reference to FIG.

[6-2. Second Modification]
In each example described above, an example in which the recipe management server 1 executes each process of FIG. 8 and FIG. 19 is shown. However, a web page with a program described so that the user terminal 3 executes some processes. The user terminal 3 may execute the part of the processing by executing data on the user terminal 3.

Specifically, this will be described with reference to FIG.
For example, the user terminal 3 may execute the interest level calculation process in step S332.
In this case, the interest level information calculated to the recipe management server 1 is transmitted. And the recipe management server 1 confirms the presence or absence of reception of interest level information in a monitoring loop process.

Each process shown in FIG. 19 will also be described.
For example, the user terminal 3 may execute the additional acquisition threshold acquisition process in step S325 and the determination process of whether the number of standby recipes in step S326 is less than the additional acquisition threshold.
In this case, a recipe addition request is transmitted to the recipe management server 1. Then, the recipe management server 1 confirms whether or not a recipe addition request has been received in the monitoring loop process.

Further, when the user terminal 3 is a terminal such as a mobile phone, and dedicated application software for using various services provided by the recipe site is installed in the terminal, the program attached to the web page data is It is also conceivable that the dedicated application software executes a part of each process executed by the recipe management server 1 without using it.
Specifically, as described above, the dedicated application software may execute the processing in step S332 in FIG. 8, the processing in steps S325 and S326 in FIG.

[6-3. Third Modification]
In each example described above, an example in which the presentation priority is set for the interested recipe acquired in the second acquisition process and transmitted to the user terminal 3 has been described. You may select and send.
For example, when a large number (for example, 100) of recipes of interest are acquired, if all of them are transmitted to the user terminal 3 (ie, presented to the user), recipe information including a search query designated by the user (condition-matching recipe) ) May not be displayed in the web page display field 5 in a short time.

Therefore, a predetermined number of recipes with high presentation priority may be transmitted to the user terminal 3 from the recipes of interest.
Moreover, you may transmit the recipe whose presentation priority is more than a fixed value from the interested recipes to the user terminal 3.
Further, the number of recipes transmitted to the user terminal 3 may be changed depending on the degree of interest. For example, when the interest level can take a value from 0 to 100, the number of transmissions of the interest recipe based on the target recipe with the interest level of 80 or more is 10 and the target recipe with the interest level of 50 or more It is good also considering the number of transmissions of the interest recipe based on this as five.

[6-4. Fourth Modification]
The interest recipe may be acquired from the condition-adapted recipe. That is, a recipe that is presumed to be highly interested in response to a user operation may be acquired as a recipe of interest from among the condition-matching recipes acquired in response to a search query specified by the user.
Thereby, only the recipe containing the search query designated by the user is presented, and the presentation priority of the condition-matching recipe is changed and presented each time according to the user's operation. That is, the recipe management server 1 resets the presentation priority of each recipe that has already been extracted as a condition-matching recipe in response to receiving the interest information.

<7. Summary>

As described in each embodiment and modification, a recipe acquisition unit as a content acquisition unit that acquires a plurality of recipes (contents) as condition-adapted recipes (condition-adapted content) based on a predetermined condition (for example, a search query) 1c, a presentation priority setting unit 1d that sets a presentation priority for a condition-matching recipe, and an interest level calculation unit 1e that calculates an interest level obtained by quantifying the user's interest according to the recipe browsing. The acquisition unit 1c executes and presents a first acquisition process for additionally acquiring a condition-matching recipe and a second acquisition process for acquiring an interest recipe (interesting content) different from the condition-matching recipe according to the degree of interest. The priority setting unit 1d resets the presentation priority so that the interested recipe is presented earlier than at least a part of the condition-matching recipe.
The first acquisition process is executed, for example, in response to the number of standby recipes that are unviewed recipes among the transmitted recipes being less than a threshold value (additional acquisition threshold value).
In the case of presenting a plurality of recipes in order, once the presentation priority of the recipe is determined once, the determined presentation priority is not often changed. Therefore, even if the user's interest (interest) changes in the process of presenting the acquired recipe according to the presentation priority, or even if the user's interest (interest) can be newly grasped, the determined presentation The priority is not optimized (reset), and it is difficult to say that the recipe is highly convenient for the user.
Therefore, the user's interest (interest) is measured in the process of presenting the recipe, and is expressed as a degree of interest.
By measuring (calculating) the degree of interest in the presentation process, it is possible to obtain information for appropriately changing the recipe presentation priority. Further, by measuring the degree of interest, it is possible to newly acquire an interest recipe that is likely to be of interest to the user.
Then, the newly acquired interest recipe based on the interest level has a higher presentation priority than at least a part of the condition conforming recipe (for example, inserted before the waiting condition conforming recipe). The presentation priority is reset. That is, the presentation priority that can follow the change in the user's interest is set as appropriate.
Accordingly, since the user is automatically presented with interest recipes one after another, there is little need to perform an additional operation for performing a new search. And since an interest recipe is shown before the waiting recipe, the recipe presentation which reflected a user's interest rapidly can be performed. And since all the recipes of interest considered to be desired by the user are presented before all of the condition-adapted recipes are transmitted to the user terminal 3, the amount of communication is reduced and the information is less than when all condition-adapted recipes are transmitted to the user terminal 3 It is possible to reduce the processing load on the processing device (recipe management server 1 or user terminal 3).
In addition, since the recipe of interest and the condition-adapted recipe are additionally acquired before all the waiting recipes are browsed, waiting for the recipe to be finished and waiting until the next recipe is presented. Can be suppressed.
Note that the recipe of interest transmitted to the user terminal 3 is presented before at least one of the many standby recipes, so that the user can browse the recipe of interest before browsing all the standby recipes. The effect of being able to be obtained. For example, when there are 900 standby recipes, the interested recipe may be presented 900th of the 900 recipes, and the remaining standby recipes may be presented 901st.
However, in order to further enhance the effect, it is desirable that the recipes of interest have a higher presentation priority than at least half of the standby recipes. Of course, in order to enhance the most effect, it is desirable to set a higher presentation priority than all standby recipes.
At this time, when a recipe that is partially viewable (that is, a recipe that is partially displayed in the web page display field 5) is used as a browse recipe, the partially viewable recipe is completely displayed by the feed operation. After being displayed, the recipe of interest is displayed. By starting presentation (display) of the recipe of interest next to a partially viewable recipe, the user can browse the recipe group naturally.
On the other hand, when a partially viewable recipe is used as a standby recipe, the recipe of interest may be presented to the user while the partially viewable recipe moves downward and the recipe of interest is presented in between. it can.

A case where many of the various processes described above are executed on the user terminal 3 side is also conceivable.
For example, the user terminal 3 transmits a plurality of recipe acquisition requests to the recipe management server 1 based on a search query designated by the user. Then, the recipe received from the recipe management server 1 is acquired as a condition-matching recipe.
And the user terminal 3 gives presentation priority to a condition adaptation recipe, and performs control which is shown on the screen of the user terminal 3 or the like.
When the user performs an operation of browsing the recipe displayed on the user terminal 3, the user terminal 3 calculates the degree of interest corresponding to the operation for each recipe.
The user terminal 3 additionally acquires a condition-matching recipe from the recipe management server 1 when the number of unread browsing recipes decreases. That is, the first acquisition process is executed.
Moreover, the user terminal 3 acquires an interest recipe from the recipe management server 1 according to the interest degree of a recipe. That is, the second acquisition process is executed.
The user terminal 3 gives the presentation priority again to the condition-matching recipe and the interest recipe, and displays it on the screen of the user terminal 3 or the like.
Thus, even when many processes are performed in the user terminal 3, the various effects described above can be achieved.

Further, as described in the second example of the interest level calculation process, the interest level may be calculated for the category (cooking category) to which the recipe belongs.
Thereby, when the user shows interest in one recipe, the degree of interest in the cooking category to which the recipe belongs is calculated high.
Accordingly, it is possible to easily identify a cooking category (field) that attracts the user's interest, and it is possible to grasp the user's interest in other recipes only by grasping the interest in a few recipes.
Further, in the process of presenting the recipe of interest belonging to the same cooking category according to the recipe that the user is interested in, it is further measured which recipe the user shows interest in the recipe of interest belonging to the same cooking category. When the interest level is calculated (that is, the interest level is calculated), the interest level can be calculated while maintaining fairness between the recipes of interest.
Specifically, for example, when the degree of interest in the recipe A (that is, the degree of interest in the cooking category X to which the recipe A belongs) is 50 points, the degree of interest in the other recipes B, C, and D belonging to the cooking category X Is also 50 points. Therefore, when calculating which recipe's interest level is high among recipes A, B, C, and D (all recipes belonging to the cooking category X), only the recipe A in which the user has shown interest is shown. Since the recalculation is not started in a high state, and the recalculation is started with the same 50 points in all of recipes A, B, C, and D, fairness between recipes A, B, C, and D The degree of relevance can be calculated while maintaining.

Furthermore, as described in the first example of the interest level calculation process, the interest level may be calculated for the recipe.
Thereby, the interested recipe according to the recipe-specific information is extracted and presented to the user.
Therefore, the interested recipe according to the feature for each recipe can be presented to the user without being bound by the cooking category.
In particular, since multiple recipes of interest across food categories can be presented, flexible interest regardless of predetermined categories (including not only cooking categories but also categories divided by cooking methods, etc.) It becomes possible to present a recipe.
Therefore, it is possible to appropriately present a recipe that is highly interested by the user.

Furthermore, as described in the process of the recipe management server, the interest level calculation unit 1e may calculate the interest level according to the browsing of the interested recipe.
Thereby, the degree of interest is further calculated for the interest recipe extracted according to the degree of interest of the user with respect to the condition-adapted recipe. Further, an interest recipe is acquired and presented based on the interest level for the interest recipe.
For example, for a user who is determined to have a high interest in a recipe related to “curry”, a recipe related to “Kema Curry”, “Mutton Curry”, “European Curry”, etc. is presented as an interest recipe. Then, the interest level for the interested recipe (recipe for “Kima Curry”, “Mutton Curry”, etc.) is calculated again. For example, if it is determined that the interest level for “Kema Curry” is high, As such, recipes such as “Zushi Keema Curry” and “Tomato Keema Curry” are extracted as recipes of interest.
That is, as the user's interest is estimated, the range of recipes acquired as the interest recipe is narrowed and deepened. In other words, the recipe field (cooking category) that the user wants to know is automatically specified.
Thereby, the information (recipe) that the user has requested can be appropriately presented, and information (recipe) with specialized contents can be presented.

And as demonstrated in the 2nd example of the 2nd acquisition processing, it is further provided with the common point extraction part 1f which extracts the common point of the recipe with the high degree of interest calculated, and the recipe acquisition part 1c is in the 2nd acquisition processing. An interest recipe may be acquired based on the common points.
In many cases, the user is not only interested in one recipe (or one cooking category) but also interested in a plurality of recipes (or a plurality of cooking categories). In such a case, in view of the interest in one recipe A, the interested recipes A1, A2,... Related to the recipe A are presented, and then in view of the interest in the recipe B that the user has shown interest in, In this case, even if the interested recipes B1, B2,... Related to the recipe B are presented, the user may be satisfied to some extent, but it may be difficult to present the interested recipe with a high degree of satisfaction.
Therefore, common points of recipes with a high degree of interest calculated so far are extracted, an interest recipe is acquired based on the common points, and presented to the user.
Specifically, if the user shows a high level of interest in the “autumn eggplant curry” and the “autumn eggplant gratin”, they are not caught in the “curry” category or the “gratin” category. You can pay attention to "Reiko". In this case, a search process or the like is performed using “Akiko” as a keyword, and a recipe related to “Akiko” is acquired as an interest recipe. In other words, it is possible to appropriately present a recipe with high user interest.
Thereby, it is possible to increase the possibility that a recipe (in other words, a recipe that greatly satisfies the user) including a keyword (foodstuff or the like) that is highly interested by the user is presented to the user.

In addition, as described in the overall flow (particularly FIG. 7), the presentation priority setting unit 1d resets the presentation priority so that the recipe of interest is presented immediately after the recipe that the user is browsing. You may go.
Thereby, when the user performs an operation of displaying the next recipe, the interested recipe is presented immediately after the recipe being browsed. In other words, the recipe of interest added before presenting the waiting condition among the condition-matching recipes is presented with the highest priority.
Accordingly, the user can immediately view the recipe of interest acquired as a result of drawing out the user's interest. Further, by displaying the interested recipe immediately after the recipe being browsed, the interested recipe can be browsed without performing an operation of returning to the previous recipe.

Further, as described in the third example of the second acquisition process, the recipe acquisition unit 1c performs the second acquisition process when an interest level greater than the maximum interest level calculated in a series of browsing sessions is calculated. May be performed.
A series of browsing sessions (same sessions) are various processes (communications) exchanged in a series of periods, for example, from connection to a server to browse recipes until connection is released.
Continuing to increase the number of recipes of interest as standby recipes may be undesirable because it increases the amount of user communication. In such a case, with the present configuration, the second acquisition process is executed to execute the second acquisition process for acquiring the interested recipe only when the interest level greater than the maximum value is calculated. Is suppressed.
Accordingly, the interest recipe acquisition process is not executed in a dark manner, and the amount of communication can be reduced. Further, in each information processing apparatus, it is possible to reduce the processing load for communication and acquisition processing.

Furthermore, as described in the first example of the interest information based on the browsing time, the interest level calculation unit 1e presents a plurality of recipes to the user when calculating the interest level based on the browsing time of the recipe. The viewing time in the state may not be used.
Thereby, the interest level can be calculated by a relatively light process of measuring the browsing time.
Accordingly, it is possible to quickly acquire an interest recipe as a subsequent process.
In addition, by not using the time period in which a plurality of recipes are presented for calculating the degree of interest, it becomes possible to more reliably determine the recipe in which the user is interested.

Furthermore, as described in the second example of the interest information based on the browsing time, the interest level calculation unit 1e may calculate the interest level based on the browsing time with respect to the information amount of the recipe.
When recipes with a large amount of information and recipes with a small amount of information coexist, it is inevitable that the browsing time for recipes with a large amount of information will be long. Therefore, the degree of interest is calculated based on the browsing time in consideration of the information amount of the recipe.
Therefore, the degree of interest can be calculated appropriately regardless of the amount of recipe information.

Then, as described in the first modification, the first acquisition process is executed in response to the number of recipes that have been acquired and that have not been browsed being less than the additional acquisition threshold. It may be set for each user according to the browsing speed of the recipe.
The browsing speed is different for each user. Further, the additional acquisition threshold value is provided for designating the timing for starting the acquisition of the next condition-adapted recipe so that the user does not have to wait for the acquisition of the recipe.
Therefore, it is considered that an additional acquisition threshold should be provided in consideration of different browsing speeds for each user.
According to this structure, since an additional acquisition threshold value is set according to a user's browsing speed, possibility that a user will wait for acquisition of a recipe can be reduced.
That is, since the additional acquisition threshold is set larger for a user with a high browsing speed, a sufficient amount of recipes for the user becomes unviewed (standby recipe), and there is a time for waiting for acquisition of the recipe. Can be suppressed.
On the other hand, since it is not necessary to set an unnecessarily large additional acquisition threshold for a user whose browsing speed is slow, it is not necessary to perform communication in which the standby recipe is excessive for the user, and the amount of communication can be suppressed.

Further, as described in the first example (FIG. 15) and the second example (FIG. 16) of the presentation priority setting process for the recipe of interest, when it is possible to present a plurality of recipes at a time, In the resetting, the presentation priority setting unit 1d may set the presentation priority for the recipe of interest so as to be presented between the recipes being presented.
In other words, the recipe of interest that has been acquired based on the user's interest is presented between the plurality of recipes being browsed.
Therefore, the presentation reflecting the change in the user's interest and the like is immediately performed. In addition, recipes that the user is likely to be interested in are displayed on the screen one after another without scrolling the user.

In each of the above examples, a recipe is given as an example of the content presented to the user, and the recipe management server 1 is given as an example of an apparatus that provides information to the user. However, these are just examples.
For example, a device in which various web pages are used as contents and a search engine server for searching for various web pages provides information may be used.
In addition, each writing in a social network in which a plurality of users transmit information may be content, and a server device that provides a function for searching for the writing may be a device that provides information.
In addition, examples of various forms of content and information providing apparatuses (information processing apparatuses) are conceivable.

In addition, the condition acquisition content is additionally acquired on the condition that the number of unviewed contents is less than the threshold (execution of the first acquisition process) has been described. However, additional acquisition is performed according to other conditions. Also good.
For example, the following first acquisition process may be executed on condition that the user continues to browse the content after a predetermined time has elapsed since the previous acquisition of the condition conforming content (or additional acquisition).
