Description

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

JP, 2013-178831, A

When presenting a plurality of pieces of information to the user, the plurality of pieces of information are often ranked according to an index indicating whether the information is useful (or sought for) by the user and presented in accordance with the ranking. For example, when presenting a search result for a search query specified by a user, the degree of agreement with the search query or the number of views by other users (in other words, how much of a plurality of search results presented as search results The presentation priority is given to each search result on the basis of information such as whether or not the user of the user selects and browses, and the information is presented to the user.
Patent Document 1 describes that the order of presentation of keywords is determined by comparing the order information of keywords linked to each information to be provided.

  However, it is not always optimal to sequentially present a plurality of pieces of information based on priority information (order information) determined before presenting to the user. For example, from the user's behavior with respect to the information already browsed by the user, there is no appropriate information to be presented thereafter among the information waiting for the presentation order to be determined and to be browsed by the user. In some cases, 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, the present invention aims to present appropriate information to the user according to the user's information browsing.

An information processing apparatus according to the present invention comprises a content acquisition unit for acquiring a plurality of contents as condition conforming content based on a predetermined condition, a presentation priority setting unit for setting a presentation priority to the condition conformance content, and browsing of content A degree of interest calculation unit for calculating the degree of interest obtained by quantifying the user's interest according to the content acquisition unit, the first acquisition processing for additionally acquiring the condition-conforming content, and the degree of interest A second acquisition process of acquiring interest content different from the condition-matched content, and the presentation priority setting unit is configured to present the interest content earlier than at least a part of the already acquired condition-matched content. To set the presentation priority to be set.
When presenting a plurality of pieces of content in order, there is not much change in the determined presentation priority once the presentation priority of the content has been determined once. Therefore, even if the user's interest changes in the process of presenting the acquired content in accordance with the presentation priority or the user's interest can be newly grasped, the determined presentation priority is optimized ((10) It is difficult to say that the content is presented with high convenience for the user without re-setting.
Therefore, in the process of presenting content, the user's interest (interest) is measured and quantified as the degree of interest.
Then, the interest content newly acquired based on the degree of interest has, for example, a presentation priority higher than at least a part of the content (waiting content) which has been acquired but not yet presented to the user (ie, The presentation priority is reset so as to be inserted before the unpresented conditional content. Therefore, the presentation priority which can follow change of a user's interest is set suitably.

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

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

The degree-of-interest calculating unit of the above-described information processing apparatus may calculate the degree of interest according to the browsing of the contents of interest.
Thus, the degree of interest is further calculated for the contents of interest extracted according to the degree of interest of the user for the condition matching content. Then, the interest content is further obtained and presented based on the degree of interest in the interest content.

The above-described information processing apparatus further includes a common point extraction unit that extracts common points of the calculated content having a high degree of interest, and the content acquisition unit determines the interest content based on the common points in the second acquisition process. You may get
The user not only shows interest in one content (or one category), but also often shows interest in a plurality of contents (or categories). In such a case, in view of the interest in one content A, the contents of interest A1, A2, ... associated with the content A are presented, and then in view of the interest in the content B that the user showed interest in, In this case, even if the content of interest B1, B2,... Related to the content B is presented, although it is possible to satisfy the user to some extent, it may be difficult to present the content of interest with high satisfaction.
Therefore, the common points of the contents having a high degree of interest calculated until then are extracted, and the interesting contents are acquired based on the common points and presented to the user.

The presentation priority setting unit of the above-described information processing apparatus may perform the reconfiguration so that the content of interest is presented immediately after the content browsed by the user.
Thus, when the user performs an operation to display the next content, the interest content is presented immediately after the content being browsed. In other words, the interest content added prior to presenting the waiting ones of 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 a degree of interest larger than the maximum value of the degrees of interest calculated in a series of browsing sessions is calculated.
A series of browsing sessions are, for example, various processes (communications) exchanged in a series of time periods, such as from connection to a server to browse content and release of the connection.
It may be undesirable for the interest content to continue to increase as the standby content, as it causes an increase in the amount of communication of the user. In such a case, in the case of this configuration, since the second acquisition process for acquiring the content of interest is executed only when the degree of interest greater than the maximum value is calculated, an opportunity to execute the second acquisition process Is suppressed.

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

The degree-of-interest calculating unit of the above-described information processing apparatus may calculate the degree of interest based on a browsing time for the amount of information of content.
When content with a large amount of information and content with a small amount of information are mixed, it is inevitable that the browsing time of the 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 information amount of the content.

In the above-described information processing apparatus, the first acquisition process is executed in response to the number of already acquired and unviewed contents becoming less than a threshold, and the threshold is determined according to the browsing speed of the content. It may be set for each user.
The browsing speed is different for each user. Also, the threshold is provided to specify the timing at which the acquisition of the next condition-adapted content is started so that the user does not have to wait for acquisition of the content.
Therefore, it is considered that the threshold should be provided in consideration of different browsing speeds for each user.

In the above-described information processing apparatus, when presentation is possible such that a plurality of contents can be browsed at one time, the presentation priority setting unit is configured to present between the contents being presented in the reconfiguration. The presentation priority for the content of interest may be set.
That is, the interest content acquired by taking the user's interest into view is presented among the plurality of contents being browsed.

In the information processing method according to the present invention, 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 to the condition conforming content, and the condition conformance A first acquisition step of additionally acquiring content, an interest level calculation step of calculating an interest level quantified by user's interest according to browsing of the content, and an interest different from the condition matching content according to the interest level A second acquiring step of acquiring content, and resetting the presentation priority so that the interest content is presented earlier than at least a part of the acquired condition-matched content.
The information processing method provides an environment for presenting information appropriate for the user according to the user's information browsing.

A program according to the present invention is a program that causes an information processing apparatus to execute processing to be 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 in response to the user's information browsing.

<1. Overall configuration>

First, the entire 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) to be presented to the user.
Also, one content means one recipe, and one recipe contains information such as the cooking procedure, the used food, and the cooking utensil.
Then, as an information processing apparatus that provides information (recipe) to the user, the recipe management server 1 is taken as an example.
Further, as a portal site for providing a service capable of searching for a recipe or posting a recipe according to a search query specified by a user, a recipe site operated (managed) by the recipe management server 1 is exemplified.

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 via the communication network 2 in a mutually communicable state with the user terminals 3, 3, 3,... In addition, the recipe management server 1 includes a user DB (Database) 50 in which information on a user is stored, a recipe DB 51 in which information on a recipe is stored, a search DB 52 in which information on search queries and search results is stored, and a recipe site It is connected to a web page DB 53 in which web page data of various web pages are stored.
The recipe management server 1 and the user terminals 3, 3, 3,...

The recipe management server 1 executes a search process for searching for a recipe in accordance with a search query specified by the user. The search query is an example of the “predetermined condition” in the claims.
In addition, processing for transmitting the recipe group extracted as the 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 will be referred to as the “condition matching recipe”. The condition matching recipe is a specific example of "condition matching content" in the claims.

When presenting the condition matching recipe to the user, instead of transmitting all the extracted condition matching recipes (for example, 1000) to the user terminal 3 at one time, a predetermined number (for example, 20) of the condition matching Send the recipe first. Then, in response to the number of unviewed recipes (unviewed ones among the already sent condition matching recipes) becoming less than the threshold while the user proceeds to browse the predetermined number of condition matching recipes. The predetermined number of condition matching recipes to be presented next are acquired from the extracted condition matching recipes and transmitted to the user terminal 3. In the following description, the threshold is referred to as "additional acquisition threshold".
A specific example is given and demonstrated. The recipe management server 1 transmits 20 selected from the 1000 condition matching recipes to the user terminal 3. Then, in the process of browsing the 20 condition matching recipes by the user, 980 condition matching recipes not sent according to the condition of the already sent and unread condition matching recipes becoming less than the additional acquisition threshold of 5 cases. Select 20 new items from and send. By transmitting a predetermined number of recipes appropriately from the condition matching recipe as the search result, unnecessary communication amount can be reduced.
In the following description, transmitted and unviewed recipes will be referred to as "waiting recipes". For example, if there are 20 transmitted recipes and there are 15 recipes read by the user (recipes displayed on the screen of the user terminal 3), the number of waiting recipes is 5.
The standby recipe is an example of “standby content” in the claims.

The recipe management server 1 also performs processing for managing recipe information and processing for managing user information. Further, as processing for presenting information (recipe) suitable for the user, processing for calculating the degree of interest of the user with respect to the recipe and the food category is performed.
The specific configuration will be described later.

The configuration of the communication network 2 is not particularly limited. For example, the Internet, intranet, extranet, LAN (Local Area Network), CATV (Community Antenna TeleVision) communication network, Virtual Private Network, telephone line A network, a mobile communication network, a satellite communication network, etc. are assumed.
Also, various examples are assumed for transmission media that constitute all or part of the communication network 2. For example, even if wired such as IEEE (Institute of Electrical and Electronics Engineers) 1394, USB (Universal Serial Bus), power line carrier, telephone line, 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 links, and terrestrial digital networks.

The user terminal 3 is a terminal used by a user who posts a recipe to the recipe management server 1 or a user who searches and browses recipe information managed by the recipe management server 1.
The user terminal 3 executes various transmission / reception processing, display processing, and the like as needed. The user terminal 3 is, for example, a PC (Personal Computer) having a communication function, a feature phone, a PDA (Personal Digital Assistant), 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. The central processing unit (CPU) 101 of the computer apparatus in each server or terminal or DB is a program stored in a read only memory (ROM) 102 or loaded from a storage unit 108 into a random access memory (RAM) 103. Execute various processes according to the program. The RAM 103 also stores data necessary for the CPU 101 to execute various processes.

The CPU 101, the ROM 102, and the RAM 103 are mutually connected 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, a touch panel and the like, a display including an LCD (Liquid Crystal Display), a CRT (Cathode Ray Tube), an organic EL (Electroluminescence) panel and the like, and a speaker. A storage unit 108 configured of a unit 107, an HDD (Hard Disk Drive), a flash memory device, and the like, and a communication unit 109 for performing 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 removable media 111 such as a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory are appropriately attached. Reading is performed.

In such a computer device, upload and download of data and programs can be performed by communication by the communication unit 109, and data and programs can be delivered via the removable medium 111.
Information processing and communication to be 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 by the CPU 101 performing processing operations based on various programs.

  Each information processing apparatus constituting 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 is limited to a single computer apparatus as shown in FIG. Alternatively, it may be configured by a plurality of computerized computer systems. The plurality of computer devices may be systemized by a LAN or the like, or may be remotely located in a communicable state by 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 a cloud computing service.

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 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 degree calculation unit 1e, a common point extraction unit 1f, and a transmission control unit. It is equipped with 1g.

  The recipe management unit 1a manages recipe information (information in which a recipe title, used ingredients, a cooking method, cooking category information to which a recipe belongs, and the like are linked) posted by the user, and stored in the recipe DB 51. For example, a recipe of "vegetable curry" submitted by a certain user is a recipe belonging to the cooking category "curry", and as ingredients used information, "potato", "carrot", "onion", "onion", "broccoli", "tomato" , "Spinach", seasonings ("salt", "peel", etc.) and things similar thereto (eg, "curry roux", etc.) are linked and stored.

  Also, the recipe management unit 1a manages a creation report posted for each recipe. The creation report is a report in which the taste and convenience of the dish felt for the recipe when another user actually cooks using the posted recipe. The creation report is linked to each recipe of the recipe DB 51 and managed.

The user management unit 1 b performs various processes to manage information of users who use various services provided by the recipe management server 1.
For example, management is performed by associating a name, an age, a gender, a contact address (such as a telephone number or an e-mail address) with a user ID that can uniquely identify a user, and storing the result in the user DB 50. Further, processing for acquiring user information from the user DB 50 is performed.

  The recipe acquisition unit 1 c performs a search process according to the search query, and extracts a condition matching recipe as a search result. Then, the recipe acquisition unit 1 c executes a process of acquiring a part of the extracted condition matching recipe. Specifically, a predetermined number (for example, twenty cases as described above) of recipes are acquired from the extracted condition matching 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 processing is executed each time the browsing of the recipe proceeds on the user terminal 3 and the number of standby contents becomes less than the additional acquisition threshold.

In addition, the recipe acquisition unit 1 c executes a process of acquiring a recipe that is likely to be of interest to the user from the behavior of the user with respect to the presented recipe as a recipe of interest. Specifically, the recipe is searched based on the degree of interest of each recipe inferred from the behavior of the user, and the extracted search result is acquired as the interest recipe. In the following description, the process of acquiring a recipe based on the interest inferred from the behavior of the user will be referred to as “second acquisition process”.
The interest recipe is an example of “interest content” in the claims.
The recipe acquisition unit 1 c is a specific example of the “content acquisition unit” in the claims.

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

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

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

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 an additional acquisition request of a recipe to be displayed on the web page data, after executing various processes, information of the additional recipe is transmitted to the user terminal 3.
The transmission of the recipe information (or the transmission of web page data including the recipe information) is performed based on the presentation priority information given to each of the recipe information.

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

An example of the 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 specified by the user is presented as a search result.
The search result presentation page can be browsed 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.
In the web page display column 5 in which the search result presentation page is displayed, together with the search query input column 7 for performing a search and the search button 8 for transmitting a search request to the recipe management server 1, a recipe group as a search result Is displayed. The web browser 4 may be configured such that the recipes are displayed one by one in the web page display field 5.
One piece of recipe information is configured by, for example, image information indicating a completed drawing of a recipe, text information indicating materials, cooking procedures, and the like.

The recipes displayed in the web page display field 5 include those which have already been displayed and those which have not. In the following description, for convenience of explanation, those which have been displayed (that is, those which are presumed to have been browsed by the user) are described as the viewing recipe 9 and those which have not been displayed yet are described as the standby recipe 10. However, although the browsing recipe 9 and the standby recipe 10 are distinguished in the explanation, there is no change such as a change in the status in practice.
Among the recipes presented as the search results, the viewable recipes are displayed as browsing recipes 9, 9, 9,... In FIG. The user performs a scroll operation (hereinafter, referred to as a feed operation) for moving the recipe information upward to browse the unviewed recipe. Also, in order to browse again the recipe that has already been viewed and has disappeared to the upper side of the web page display field 5, a scroll operation to move the recipe information downward (hereinafter, referred to as a return operation) is performed.
Also, as shown in FIGS. 5A and 5B, below the browsing recipes 9, 9, 9,..., Recipes that the user has not yet browsed are arranged as standby recipes 10, 10, 10,. . Although the standby recipe 10 is not actually disposed below the viewing recipe 9, it can be regarded as being virtually disposed in an invisible state, so such a representation is used. . The same applies to the following description.

As shown in FIG. 4, among the four recipes displayed in the web page display column 5, three cases are in a state where all information can be browsed, and are regarded as browse recipes 9, 9, 9. In addition, one remaining case is in a state where a part of the recipe information can be viewed.
With regard to a recipe in which only a portion of the recipe information can be viewed, since a portion can be viewed, it may be a viewing recipe 9 as shown in FIG. 5A, or all information can not be viewed, As shown in FIG. 5B, it may be a standby recipe 10. In the case where the recipe which can be browsed only by a part of the recipe information is regarded as the standby recipe 10, the standby recipe 10 changes to the browsing recipe 9 when the user can browse all the recipe information.
Also, if the recipe information (i.e., viewing recipe 9) once viewed by the user's return operation has moved to the lower part of the web page display field 5, the location has already been viewed even at the position of the standby recipe 10. Since it is a recipe, it becomes browsing recipe 9.

  The recipe management server 1 is additionally provided with functions necessary to transmit and receive various types of information, and to perform an authentication process in response to a user's login operation. The authentication process is a process of collating the user ID (Identification) as the login information transmitted from the user terminal 3 and the login password 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 a program. However, the processing of all or part of each configuration described below may be realized by hardware.

When each function is realized by software, each function does not have to 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.
In addition, each function may be distributed to a plurality of information processing apparatuses. Furthermore, one of the functions may be realized by a plurality of information processing apparatuses.

<4. DB>

The respective DBs 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 made accessible. For example, all of each DB may be formed in a storage unit in the same system as the recipe management server 1, or all or part of each DB may be separated, or a computer system such as a remote place May be provided. Of course, each DB does not have to be formed in one device (for example, one HDD). Further, each DB does not have to be configured as one DB. For example, information stored as the user DB 50 may be stored and managed by a plurality of user DBs (for example, a user DB for login and a user DB for transaction). Each DB described below is merely an example of storage units of 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 the service provided by the recipe management server 1. For example, personal information such as a login password, a name, an age, a gender, and an e-mail address is linked and stored for one user ID (Identification) that can specify one user.

In addition, preference information for each user may be stored in the user DB 50. The preference information is the user's favorite food (preferred food) or disliked food (non-preferred food) determined by the recipe management server 1 according to the behavior of the user. The preference information is used when the user performs a recipe search.
In each of the examples described below, user information is used to infer the user's interest in the recipe. The user information for estimating the interest is, for example, the browsing speed in the web page, and such information is stored in the user DB 50.
When the above-mentioned additional acquisition threshold is a numerical value according 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 in which information of a recipe posted by a user is stored. Specifically, for the recipe ID that can identify each recipe, a user ID specifying a user who has posted the recipe, posting date information, cooking category information to which the recipe belongs, and used food information of the recipe (quantity Image information such as the cooking procedure of the recipe and the cooking image (a finished cooking image or a cooking image during cooking), etc., and by other users who have actually used the recipe (created cooking) A creation report ID specifying the posted creation report is linked and stored.

  Further, each recipe ID is associated with information of procedure outline content indicating an outline of a cooking procedure of the recipe.

In addition, URL (Uniform Resource Locator) information of a detailed page of a recipe may be associated with the recipe ID and stored.
Furthermore, the recipe DB 51 stores information of a creation report posted for each recipe. As the information of the creation report, text information indicating the contents of the report, a user ID capable of identifying the poster, posting date information, and the like are stored.

[4-3. Search DB]
The search DB 52 is a DB in which search results corresponding to the search query are stored. Specifically, a plurality of recipes are linked and stored as search results according to search names such as food names such as "curry" and "hamburger" and food names such as "mushroom" and "tomato" .
In order to avoid executing 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 provided to the user by the recipe management server 1. Specifically, it is web page data such as a recipe search page, a 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 as a structured document file such as Hyper Text Markup Language (HTML) or Extensible Hyper Text Markup Language (XHTML), for example.

<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 to display the login screen using the user terminal 3, the user terminal 3 executes processing for requesting login screen information (that is, web page data for displaying the login screen) in step S101. Do.

When the 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 the login screen information transmission process in step S201.
Thus, 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 a login information transmission process of transmitting login information (user ID and login password) corresponding to the user's input operation to the recipe management server 1.

When 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 the information stored in the user DB 50 to determine whether or not the user can login, and authenticates the login availability information. As a result, the user terminal 3 is notified. The authentication result may be sent to the user terminal 3 and the webpage data of the top page of the recipe site may be sent. As a result, user authentication is performed, and the top page of the recipe site is displayed on the user terminal 3.

  A series of flows shown in FIG. 6 show the case where it is determined that login is possible in the authentication process of 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 in response to this, the recipe management server 1 executes the process of step S202.

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

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

Subsequently, in step S205, the recipe management server 1 performs processing of setting a presentation priority for 1000 recipes extracted as a search result. The presentation priority is given a higher value as the recipe is more suitable for presentation to the user. For example, it is conceivable to consider a search query specified by the user. Specifically, when the user specifies "chicken" as part of the search query, the presentation priority is set higher for the recipe used as the main food than the recipe using the "chicken" as the non-main food May be
Moreover, it is conceivable that it is based on the user's favorite food. A higher priority may be set for a recipe that uses more user's favorite food as a used food. In addition, the information of the favorite food and the non-favored food is stored in the user DB 50.
In addition, a recipe that uses seasonal ingredients according to the season may have a higher presentation priority, or a recipe with a greater number of views from other users or creation report postings may have a higher presentation priority. May be set, or the higher the presentation priority may be set for the recipe having the greater number of browsing in the latest predetermined time (predetermined period). Of course, the presentation priority may be set in consideration of these factors in a combined manner, or the presentation priority may be set by other factors. Here, only an example is given.

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

Subsequently, in response to the user performing an operation indicating an interest (interest) in any of the browsing recipes 9, the user terminal 3 executes a process of transmitting interest information in step S104. .
The interest information transmitted to the recipe management server 1 includes at least information specifying a target recipe (for example, recipe ID) and information specifying an operation type (that is, what operation was performed as an operation indicating interest). Be

Here, some specific examples of operations indicating interest (hereinafter, interest operations) will be shown.
(1) Recipe detailed page browsing operation (2) favorite registration operation (3) printing operation (4) highlight operation (5) click operation (6) predetermined browsing time lapse

As a recipe as a search result presented on the user terminal 3, an outline of the recipe is presented as shown in FIG. 4 and FIG. Therefore, when the user actually uses (cooks) a recipe of interest, he often browses the recipe detail page to browse the cooking procedure.
Therefore, the operation of browsing the recipe detail page is considered to be the operation of interest.

In addition, there is a high possibility that a recipe which is considered to be browsed later may be registered as a favorite recipe so that the search operation does not have to be performed again.
Therefore, the operation of interest is also made with respect to the favorite registration operation.

  Then, the printing operation of the recipe detail page is very likely to be performed when it is intended to actually use the recipe. The printing operation is also an operation of interest.

  Furthermore, an operation of highlighting text information and the like related to a recipe (operation of selecting a part of text) is likely to be performed in a state where information of the recipe is browsed. The highlight operation is an operation of interest because it can be said that viewing the text is in a state of interest in the recipe.

A portion of the web page display column 5 of the web browser 4 where the recipe information is displayed (a click operation on the region of the viewing recipe 9 in FIG. 4 may be similarly performed in a state where the information of the recipe is viewed) Therefore, the click operation is also an operation of interest.
In addition to the case where a page transition occurs due to the user's click operation, the user terminal 3 performs no processing (that is, nothing happens when clicked). Ru.

Moreover, when the time while browsing the recipe has passed a predetermined time (predetermined browsing time), it can be said that the interest in the recipe is high. Although the predetermined browsing time lapse may be determined without the user performing an operation using an input device such as a mouse, it is defined as an interest operation for the sake of convenience.
The user may leave the user terminal 3 with the browsing recipe 9 being displayed. In this case, while the same browsing recipe 9 continues to be displayed on the screen of the user terminal 3, a predetermined browsing time may elapse, and it may be determined that the recipe is of interest. In order to avoid this, the user can view the browsing recipe 9 displayed on the user terminal 3 by determining whether the user is operating the mouse or the keyboard (for example, whether the cursor is moving or the like). It may be determined whether or not. In addition, when a plurality of software programs including the web browser 4 (provided that something is displayed on the screen) is operating on the user terminal 3, the web browser 4 on which the browsing recipe 9 is displayed is The presence or absence of the operation of interest may be determined based on whether or not it is in the active state.
By determining whether the user has actually browsed the recipe, it is possible to grasp an appropriate browsing time, and in turn, it is possible to appropriately estimate the presence or absence and the degree of interest.

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

It returns to the explanation of FIG.
In step S207, the recipe management server 1 that receives the interest information indicating what kind of interest operation has been performed for which recipe performs a process of calculating the degree of interest.
The degree-of-interest calculation process is a process of calculating the degree of interest for the browsing recipe 9 and is executed each time interest information is received. Specific examples will be described later.

  After calculating the degree of interest, 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 inferred. A specific example will be described later.

Subsequently, in step S209, the recipe management server 1 executes a process of setting a presentation priority to the acquired interest recipe. The presentation priority of the interest recipe set here is set to a value higher than a part of the recipes already transmitted to the user terminal 3.
Then, in step S210, the recipe management server 1 executes a transmission control process of transmitting, to the user terminal 3, information in which the interest recipe and the presentation priority are linked.
This will be specifically described with reference to FIG.
In the state shown in FIG. 7, a part of the condition matching recipes 11, 11,... And the interest recipes 12, 12,. Is located below. In the standby recipes 10, 10, ..., the interest recipes 12, 12, ... are arranged above the condition matching recipes 11, 11, .... 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 interest recipe 12 can first be viewed.

Return to the explanation of FIG.
The user may perform a scroll operation to browse the standby recipe 10 in the process of browsing the condition matching recipe, the interest recipe, and the like transmitted to the user terminal 3.
The user terminal 3 accepts the scroll operation in step S105 in accordance with the scroll operation of the user. For example, a part of standby recipes 10 is presented as a viewing recipe 9 in the web page display field 5 of the web browser 4 by accepting a scroll operation as a sending operation.
As the reading of the waiting recipe 10 proceeds (that is, as the waiting recipe 10 changes to the browsing recipe 9), the number of waiting recipes 10 decreases. Then, in response to the number of standby recipes 10 becoming less than the additional acquisition threshold (for example, five), 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 the presence / absence of the unsent condition matching recipe. In this example, since only 20 of the 1000 condition matching recipes are sent, 980 unsent recipes exist.
Therefore, in step S212, the recipe management server 1 acquires 20 of the 980 unsent condition-adapted recipes based on the presentation priority.
Subsequently, in step S213, the recipe management server 1 executes a process of transmitting the acquired twenty condition matching recipes to the user terminal 3.
Thereby, in the user terminal 3, 20 waiting recipes 10 waiting for browsing of the user are added.

The flow of the 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. Processing of recipe management server]
An example of the flow of processing executed by the recipe management server 1 in order to realize the above-described entire 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 processing corresponding to each of them. Therefore, the recipe management server 1 executes monitoring loop processing to monitor whether or not various information has been received.
Specifically, as shown in FIG. 8, by repeatedly executing the processes of steps S301, S311, S321, and S331, the presence or absence of reception of login information, the presence or absence of reception of a search query, the presence or absence of reception of a recipe addition request, interest information Monitor the reception of When it is determined that any information has been received, the corresponding processing is executed.

For example, the recipe management server 1 that has checked the reception status of the login information in step S301 executes the processing in steps S302 and S303 only when it is determined that it 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 notifies the user terminal 3 of the authentication result in the subsequent step S303. Run.
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 executes the search process according to the search query in step S312 to acquire the condition matching recipe as the search result, and the condition in the subsequent step S313. Perform processing to set the presentation priority for each matching recipe.
The condition matching recipe includes a recipe that draws the user's interest, but also a recipe that does not draw the user's interest very much. It is desirable for the recipe management server 1 to set the presentation priority higher for recipes that attract the user's interest. For this purpose, the recipe management server 1 may calculate the presentation priority using information specific to the user (e.g., preference information, information on owned cooking appliances, etc.).

Then, in step S 314, the recipe management server 1 executes a process of transmitting a part (20 cases in the above example) of the condition matching recipes to the user terminal 3.
After the process of step S314, the recipe management server 1 returns to the monitoring loop process again.
When there are few condition matching recipes, it is also conceivable to transmit all the condition matching recipes extracted as the search result in the process of step S314.

Furthermore, the recipe management server 1 having 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 at the user terminal 3 becoming less than the additional acquisition threshold.
If there is an unsent condition matching recipe, the recipe management server 1 executes a first acquisition process of acquiring a predetermined number of recipes from the unsent condition matching recipe in step S323. However, if the number of unsent condition matching recipes does not reach a 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 the 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.

Further, the recipe management server 1 that has received the interest information in step S331 executes a process of calculating the degree of interest in step S332.
Two examples of the interest level calculation process will be described based on FIG. 9 and FIG.

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

Subsequently, in step S403, the recipe management server 1 calculates the degree of interest, and executes a process to be applied to the target recipe. With regard to the assignment of the interest level, the calculated interest level may be assigned as it is, or one obtained by adding the interest level calculated this time to the interest level given so far may be reassigned.
The degree of interest calculated may be changed according to the type of the interest operation performed by the user. For example, the level of interest is calculated so that the operation (recipe detailed page browsing operation) as described in the above (1) where a strong interest in the recipe is inferred or the operation (favorite registration operation) as (2) May be Further, the operation (click operation) as described in the above (5) or the like may be calculated to have a low degree of interest.

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

In step S502, the largest cooking category may be the target category, or the smallest cooking category may be the target category. For example, the cooking category "curry" belongs to the cooking category "Indian curry" and the cooking category "Japanese style curry" as lower categories. Under the cooking category "Indian curry", the cooking category "Kima curry" and the cooking category "Mutton curry" belong. The recipe "Kima curry from my home" is a recipe belonging to the cooking category "curry", is a recipe belonging to the cooking category "India curry", and is also a recipe belonging to the cooking category "Kima curry".
Therefore, the target category may be the cooking category "curry", the cooking category "indian curry", or the cooking category "key ma curry".
In addition, when acquiring the interest recipe described later, if the number of interest recipes is too large, it is desirable to set the lower food category as the target category, and conversely, when the number of interest recipes is too small, the upper ranks It is desirable to target the food category of

  The recipe management server 1 specifying the target category specifies the operation type of the interest operation 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.

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

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

If there is a recipe whose degree of interest has newly reached a predetermined value or more in the immediately preceding step S332, the recipe management server 1 has an interest based on the recipe (that is, a recipe whose degree of interest has newly reached a predetermined value or more) in step S602. Execute processing to acquire a recipe.
For example, other recipes which the user who browsed the recipe tends to browse, recipes registered in the favorite, and the like are searched and acquired.
In addition, a recipe having a common keyword such as ingredients, cooking methods, and cooking utensils included in the recipe is searched and acquired.

The recipe acquired by the second acquisition process may be a condition matching recipe already extracted based on the search query of the user.
For example, when the condition matching recipe acquired in step S312 in FIG. 8 includes recipe A and recipe B, the presentation priority of recipe A is the first, and the presentation priority of recipe B is the 900th. The recipe B is presented to the user at a considerable later date, and the possibility of the user actually browsing is low.
However, if the recipe B is acquired as the interest recipe in step S602 of FIG. 11, the recipe B can be regarded as a recipe that is highly likely to be of interest to the user. Then, in the process to be described later, the recipe B is set to a presentation priority higher than the 900th and presented to the user.

~ 5-2-4. Second example of second acquisition process ~
Next, a second example of the second acquisition process (FIG. 12) will be described.
In the second example of the second acquisition process, the interest recipe is acquired based on the common points of the high interest recipes.
First, in step S701, the recipe management server 1 acquires a recipe whose degree of interest has reached a predetermined value or more. This process is a process performed based on the degree of interest set after the user last designated the search query, and when the user designates another search query again, the degree of interest set in the recipe is It is reset (ie, there is no recipe whose degree of interest is higher than a predetermined value).
However, if multiple search operations with different search queries are close to the latest time zone, the degree of interest may not be reset.

  Subsequently, in step S702, the recipe management server 1 executes processing for extracting common points between recipes. The common points between the recipes are, for example, food materials, utensils, and cooking methods, and can be obtained, for example, by text analysis of recipe information. Of course, these pieces of information may be linked to the recipe in advance and managed as keywords. When managing the association 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 an interest recipe.

To 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 using the user terminal 3, the same session is made while performing some operation continuously (or without passing a non-operation time longer than a predetermined time) . For example, if a recipe search is performed one day later after searching for a recipe, each session is a separate session.
Alternatively, the operation of browsing a plurality of recipes presented in response to one search operation may be the same session. In this case, when a recipe search is performed using different keywords, it is considered as another session. The same session at this time can be described 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. Do.
When the maximum value of the degree of interest is updated, the recipe management server 1 executes a process of storing the updated maximum value of the degree of interest in step S803.
Then, in step S804, the recipe management server 1 acquires an interest recipe corresponding to the recipe to which the updated degree of interest is given.
The interest recipe may be acquired based on a keyword such as a food, a cooking method, or a cookware included in the information of the recipe to which the degree of interest given the maximum value is given as in the first example of the second acquisition processing Alternatively, as in the second example of the second acquisition process, acquisition may be performed based on common points extracted from a plurality of recipes (for example, top three among recipes having a large degree of interest).

It returns to the explanation of FIG. 8 again.
The recipe management server 1 which has calculated the interest level calculated based on the user's interest operation and acquired the interest recipe based on the interest level sets the priority of the interest recipe in the subsequent step S334. Run.
In the presentation priority setting process for the interest recipe, for example, the interest recipes 12, 12,... Are arranged above the standby recipes 10, 10,. Set the presentation priority as follows.
The recipe management server 1 having set the presentation priority executes transmission control processing in the subsequent step S335. In this process, information on the recipe of interest and information on the given presentation priority are transmitted to the user terminal 3. On the user terminal 3, a display based on the presentation priority is performed.
After the process of step S335, the recipe management server 1 returns to the monitoring loop process again.

  The processes in steps S301, S311, S321, and S331 as the monitoring loop process shown in FIG. 8 are merely examples, and other than this, the presence or absence of the web page data request, the presence or absence of the user information change request, etc. The process of confirming the may be included in the monitoring loop process.

  Here, regarding the presentation priority setting process for the interest recipe, two other examples other than those described in FIG. 7 will be described.

To 5-2-6. First Example of Presentation Priority Setting Process for Interesting Recipes ~
In the first example (FIG. 14, FIG. 15) of the presentation priority setting process for the interest recipe, the presentation priority is set such that the interest recipe 12 is displayed between the displayed recipes.
FIG. 14 shows a state before the transmission control process of step S335 (FIG. 8) is performed. That is, condition matching recipes 11, 11,... With presentation priorities 121, 92, 84, 81, 74, 67, 66,. It is done. It is assumed that a recipe with a high presentation priority value is preferentially presented to the user.

FIG. 15 shows the state after the transmission control process of step S335 (FIG. 8) is performed. That is, the presentation priority = 91, 90, 89, 88, ... is set for the interest recipe 12, 12, ..., and the condition matching recipe 11 and the presentation priority are set to the presentation priority = 92. It is arrange | positioned so that it may be inserted between the condition matching recipes 11 made into = 84.
In other words, the presentation priorities of the recipes of interest 12, 12, ... are arranged between the recipe of presentation priority = 92 and the recipe of presentation priority = 84 displayed in the web page display column 5. Thus, the presentation priority is set (step S334 in FIG. 8).

To 5-2-7. Second Example of Presentation Priority Setting Process for Interesting Recipes ~
Next, a second example (FIGS. 14 and 16) of the presentation priority setting process for the interest recipe will be described.
In the second example of the presentation priority setting process for the interest recipe, a new presentation priority is also set for the recipe already transmitted to the user terminal 3.
The description of the state (FIG. 14) before the transmission control process of step S335 (FIG. 8) is performed will be omitted.
The state after the transmission control process of step S335 (FIG. 8) is performed is shown in FIG. As in the condition matching recipe 11 in which the presentation priority shown in FIG. 16 is updated to 81 → 90, a new presentation priority is also set for the recipe already transmitted to the user terminal 3.
Then, the condition matching recipe 11 whose presentation priority is updated as 81 → 90 is rearranged above the condition matching recipe 11 whose presentation priority is 84. That is, also regarding the recipe already transmitted to the user terminal 3, the layout change according to the new presentation priority is performed, and the user browses in the order based on the new presentation priority.

In the presentation priority setting process for the interest recipe in step S335 (FIG. 8), the presentation priority may be reset including the viewing recipes 9, 9,... Already browsed by the user.
Further, in this case, the browsing recipes 9, 9, ... may be rearranged based on the new presentation priority, or may not be rearranged.
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 column 5 are rearranged. It may change. This makes it possible to highlight a recipe that is meaningful to the user and attract the user's attention.
In addition, if the browsing recipes 9, 9, ... are not rearranged based on the new presentation priority, the user is looking for the browsing recipe 9 already browsed when the user browses the browsing recipe 9 by return operation. There is no need to know where the viewing recipe 9 has been placed by relocation.

[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 the user's operation. The transmission process of the interest information performed by the user terminal 3 is executed by, for example, a program attached to the web page data transmitted by the recipe management server 1 to the user terminal 3. In other words, the web page data is programmed so that the user terminal 3 transmits the interest information based on various conditions.
In addition, when dedicated application software is executed on the user terminal 3, a program defining various processing contents to be executed by the user terminal 3 may be incorporated in the application software.

Here, an example will be described as to what conditions are met when the interest information based on the viewing time (interest information sent when the above (6) is satisfied) is satisfied.
In the first example, the browsing time in a state in which the number of recipes displayed in the web page display field 5 is plural is not used to determine whether or not to transmit interest information.
Specifically, it is unclear which recipe is being viewed, regardless of how much the user's viewing time is increased in the state as shown in FIGS. 7 and 14 to 16. Time based interest information 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 field 5, the browsing time is measured and, as necessary, interest information based on the browsing time is transmitted.

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

Subsequently, in step S903, the user terminal 3 performs a process of setting a predetermined browsing time. The predetermined browsing time set here is a threshold for determining whether to transmit interest information. That is, the predetermined browsing time is set according to the amount of information of the recipe acquired in the previous process.
After setting the predetermined browsing time, the recipe management server 1 determines in step S904 whether or not the browsing time for the target recipe has exceeded the predetermined browsing time.
If the predetermined browsing time has been exceeded (is elapsed), the user terminal 3 executes a process of transmitting the interest information based on the browsing 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 a change in the browsing target (that is, has the user browsed another recipe).
If it is determined that the user has browsed another recipe (the browsing target recipe has changed), the user terminal 3 executes the process of step S901 again.
In addition, when the browse target recipe is the same, the user terminal 3 continuously executes the processes of steps S904 and S906.

In addition, although the example which the user terminal 3 performs each process shown in FIG. 18 was mentioned 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 having received the interest information executes the processing of steps S902 and S903 from the information 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 it is determined whether or not a predetermined browsing time in step S904 has elapsed.
Then, if the predetermined browsing time has elapsed, the recipe management server 1 transmits the interest recipe to the user terminal 3 by executing the processing of steps S332 to S335 in FIG. 8.

<6. Modified example>

[6-1. First Modified Example]
A modification of the series of processes of 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 checks whether reception of login information, reception of search query, reception of waiting recipe number information, and reception of interest information are performed in monitoring loop processing that is continuously executed.

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

The recipe management server 1 that has received the information on the number of waiting recipes in step S321 'acquires the additional acquisition threshold according to the user in step S325. The information on the additional acquisition threshold is stored, for example, in the user DB 50.
The additional acquisition threshold is set in accordance with the browsing speed of the user. That is, it is desirable to set the additional acquisition threshold high for users with a high browsing speed and to set low for the users with a low browsing speed.

Subsequently, in step S256, the recipe management server 1 determines whether the number of standby recipes received from the user terminal 3 is less than the additional acquisition threshold. 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 checks in step S322 whether or not there is a condition matching recipe that has not been transmitted, and then executes the first acquisition process of step S323.
The processes in steps S322 to S324 are the same as the processes described in FIG.

6-2. Second Modified Example]
Although the recipe management server 1 executes each process of FIGS. 8 and 19 in each example described above, a web page with a program described so that the user terminal 3 executes a part of the process is provided. The user terminal 3 may execute the partial process 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 of step S332.
In this case, the calculated degree of interest information is transmitted to the recipe management server 1. Then, the recipe management server 1 confirms whether or not the degree of interest information has been received in the monitoring loop process.

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

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 used. It is also conceivable that dedicated application software executes a part of each process executed by the recipe management server 1 without using it.
Specifically, the dedicated application software may execute the process of step S332 of FIG. 8 and the processes of steps S325 and S326 of FIG. 19 in the same manner as described above.

6-3. Third Modified Example]
In each of the examples described above, an example in which the presentation priority is set for the interest recipe acquired in the second acquisition processing and transmitted to the user terminal 3 has been described, but a part of the interest recipe for which the presentation priority is set is further described. You may select and send.
For example, when a large number (for example, 100 cases) of interest recipes are acquired, if all are transmitted to the user terminal 3 (ie, presented to the user), recipe information (condition matching recipe) including a search query specified by the user ) May not be displayed in the web page display field 5 in the middle.

Therefore, a predetermined number of recipes with high presentation priority may be transmitted to the user terminal 3 from among the recipes of interest.
Moreover, you may transmit the recipe whose presentation priority is a fixed value or more to the user terminal 3 out of the interest recipe.
Furthermore, the number of recipes to be transmitted to the user terminal 3 may be changed according to the degree of interest. For example, when the degree of interest can be taken from 0 to 100, the number of transmissions of the interest recipe based on the target recipe with 80 or more interest is 10, and the target recipe with 50 or more interest The number of transmissions of interest recipes based on may be five.

6-4. Fourth Modified Example]
The interest recipe may be obtained from among the condition matching recipes. That is, among the condition matching recipes acquired according to the search query designated by the user, a recipe which is estimated to be highly interested according to the user operation may be acquired as an interest recipe.
Thus, only the recipe including 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, in response to the reception of the interest information, the recipe management server 1 resets the presentation priority of each recipe already extracted as the condition matching recipe.

<7. Summary>

As described in each embodiment and modification, a recipe acquisition unit as a content acquisition unit that acquires a plurality of recipes (content) as a condition matching recipe (condition meeting content) based on a predetermined condition (for example, a search query) 1c, a presentation priority setting unit 1d that sets a presentation priority to a condition matching recipe, and an interest degree calculation unit 1e that calculates an interest degree obtained by quantifying the user's interest according to browsing of the recipe; The acquisition unit 1c performs a first acquisition process of additionally acquiring a condition matching recipe and a second acquisition process of acquiring an interest recipe (interest 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 interest recipe is presented earlier than at least a part of the condition matching recipe.
The first acquisition processing is executed, for example, in response to the number of waiting recipes which are unviewed recipes among the transmitted recipes becoming less than the threshold (additional acquisition threshold).
When presenting a plurality of recipes in order, there is not much change in the determined presentation priority after the presentation priority of the recipe has been determined once. Therefore, even if the user's interest changes in the process of presenting the acquired recipe according to the presentation priority, or if the user's interest can be newly grasped, the determined presentation There is no need to optimize (re-set) the priority, and it can not be said that the recipe presentation that is convenient for the user is made.
Therefore, in the process of presenting the recipe, the user's interest (interest) is measured and quantified as the 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. Also, by measuring the degree of interest, it is possible to newly acquire an interest recipe that is likely to be highly interesting to the user.
Then, the newly acquired interest recipe based on the degree of interest has a higher presentation priority than at least a part of the condition matching recipe (for example, is inserted before the waiting condition matching recipe) The presentation priority is reset. That is, the presentation priority which can follow change of a user's interest is set suitably.
Therefore, since the user is automatically presented with his / her interest of interest recipes one after another, there is less need to perform additional operations and the like for performing a new search. Then, since the interest recipe is presented prior to the waiting recipe, it is possible to perform a recipe presentation that quickly reflects the user's interest. Then, since the interest recipe considered to be desired by the user is presented before all of the condition matching recipes are transmitted to the user terminal 3, the reduction of communication volume and information is more than transmitting all the condition matching recipes to the user terminal 3. It is possible to reduce the processing load on the processing apparatus (the recipe management server 1 and the user terminal 3).
In addition, because interest recipes and condition matching recipes are additionally acquired before all the waiting recipes are viewed, browsing of the recipes is finished, and waiting time occurs until the next recipe is presented. Can be suppressed.
Note that the interest recipe transmitted to the user terminal 3 is presented before at least one of a large number of standby recipes, so that the user browses the interest recipe before browsing all the standby recipes. The effect of being able to For example, if there are 900 standby recipes, the 900th interest recipe may be presented out of the 900 and the remaining standby recipes may be presented 901th.
However, in order to further enhance the effect, it is desirable that the interest recipe is set to have a presentation priority higher than at least half of the waiting recipes. Of course, in order to achieve the highest effect, it is desirable to set a higher presentation priority than all the standby recipes.
At this time, in the case where a recipe in which a part is viewable (that is, a recipe in which a part is displayed in the web page display column 5) is used as a view recipe, the partially viewable recipe is completely After being displayed, the recipe of interest is displayed. By starting the presentation (display) of the interest recipe next to the partially viewable recipe, the user can browse the recipe group naturally.
On the other hand, when the recipe which can be partially browsed is a standby recipe, the recipe of interest can be appealed to the user by presenting the recipe of interest while the recipe which can be partially browsed is moved downward. it can.

It is also conceivable that the user terminal 3 executes many of the various processes described above.
For example, the user terminal 3 transmits a plurality of recipe acquisition requests to the recipe management server 1 based on a search query or the like specified by the user. Then, the recipe received from the recipe management server 1 is acquired as a condition matching recipe.
Then, the user terminal 3 gives presentation priority to the condition matching recipe, and performs control to present the recipe on the screen of the user terminal 3 or the like.
When the user performs an operation of browsing a 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 the condition matching recipe from the recipe management server 1 when the number of unread standby recipes decreases. That is, the first acquisition process is performed.
Also, the user terminal 3 acquires an interest recipe from the recipe management server 1 according to the degree of interest of the recipe. That is, the second acquisition process is performed.
The user terminal 3 gives presentation priority to the condition matching recipe and the interest recipe again, and displays the same on the screen of the user terminal 3 or the like.
Even when many processes are performed by the user terminal 3 as described above, 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 (dish category) to which the recipe belongs.
Thus, when the user shows an interest in one recipe, the degree of interest in the food category to which the recipe belongs is calculated to be high.
Therefore, it is possible to easily identify a food category (field) that is intriguing to the user, and it is possible to grasp the user's interest in other recipes only by grasping the interest in a few recipes.
In addition, in the process of presenting an interest recipe belonging to the same food category according to a recipe in which the user is interested, further measuring which recipe the user shows interest among the interest recipes belonging to the food category In the case of calculating the degree of interest, it is possible to calculate the degree of interest while maintaining fairness among the interest recipes.
Specifically, for example, when the degree of interest in recipe A (that is, the degree of interest in food category X to which recipe A belongs) is 50 points, the interest levels of other recipes B, C, D belonging to food category X Also 50 points. Therefore, when calculating which of the recipes A, B, C, and D (all are recipes belonging to the food category X) have a high degree of interest, only the recipe A that the user indicated interest has Recalculation is not started in a high state, but recalculation is started in the state of the same 50 points for all of the recipes A, B, C, D. Therefore, fairness among the recipes A, B, C, D Calculation of the degree of association can be performed while

Furthermore, as described in the first example of the interest level calculation process, the interest level may be calculated for the recipe.
Thereby, the interest recipe corresponding to the recipe-specific information is extracted and presented to the user.
Therefore, it is possible to present the user with an interest recipe according to the characteristics of each recipe regardless of the food category.
In particular, since it is possible to present a plurality of interest recipes across food categories, flexible interest is achieved regardless of predetermined categories (including not only food categories but also categories divided according to cooking methods etc.) It is possible to present a recipe.
Therefore, it is possible to appropriately present a recipe with high user interest.

Furthermore, as described in the processing of the recipe management server, the interest level calculation unit 1e may calculate the interest level according to the viewing of the interest recipe.
Thereby, the degree of interest is further calculated for the interest recipe extracted according to the degree of interest of the user for the condition matching recipe. Then, the interest recipe is further acquired and presented based on the degree of interest in the interest recipe.
For example, for a user who is determined to be highly interested in a recipe related to "curry", recipes related to "key ma curry", "mutton curry", "western curry" and the like are presented as interesting recipes. Then, when the degree of interest in the concerned interest recipe (such as a recipe related to "key ma curry" or "mutton curry") is calculated again, for example, it is determined that the degree of interest for "ki ma curry" is high, the recipe related to "key ma curry" As such, recipes such as “Kizuma curry of eggplant” and “Kima curry of tomato” are extracted as interesting recipes.
That is, as the user's interest is inferred, the range of the recipe acquired as the interest recipe is narrowed and deepened. In other words, the field (cooking category) of the recipe that the user wants to know is automatically identified.
As a result, it is possible to properly present the information (recipe) that the user has requested, and to present information (recipe) of specialized contents.

Then, as described in the second example of the second acquisition process, the method further includes the common point extraction unit 1 f that extracts common points of recipes having high calculated degrees of interest, and the recipe acquisition unit 1 c performs the second acquisition process. An interest recipe may be obtained based on the common points.
Users often show interest not only for one recipe (or one food category) but also for multiple recipes (or multiple food categories). In such a case, in view of the interest in one recipe A, the interest recipes A1, A2,... Associated with the recipe A are presented, and then in view of the interest in the recipe B that the user showed interest, Even when the interest recipes B1, B2,... Associated with the recipe B are presented this time, although it is possible to satisfy the user to some extent, it may be difficult to present a highly satisfying interest recipe.
Therefore, common points of recipes having a high degree of interest calculated until then are extracted, and an interest recipe is acquired based on the common points and presented to the user.
Specifically, when the user shows a high interest in "Aki Ayako's curry" and "Aki Ayako's gratin", the user has a common point "Autumn" without being caught in the "curry" category or the "Gratin" category. You can pay attention to "Saiko". In this case, a search process or the like is performed with "Akiko" as a keyword, and a recipe related to "Akiko" is acquired as an interest recipe. In other words, it is possible to properly present a recipe with high user interest.
As a result, it is possible to increase the possibility that the user can be presented with a recipe (in other words, a recipe that greatly satisfies the user) including a keyword (food or the like) in which the user is highly interested.

In addition, as described in the entire flow (in particular, FIG. 7), the presentation priority setting unit 1d resets the presentation priority so that the recipe of interest is presented immediately after the recipe viewed by the user. You may go.
Thereby, when the user performs an operation of displaying the next recipe, the interest recipe is presented immediately after the recipe being browsed. In other words, the interest recipe added before presenting the waiting ones among the condition matching recipes is presented with the highest priority.
Therefore, the user can immediately view the interest recipe acquired as a result of capturing the user's interest. Also, by displaying the recipe of interest immediately after the recipe being browsed, the recipe of interest can be browsed without performing an operation to return to the previous time or the like.

In addition, as described in the third example of the second acquisition process, the recipe acquisition unit 1c performs the second acquisition process when the degree of interest is calculated to be larger than the maximum value of the degrees of interest calculated in the series of browsing sessions. You may
A series of browsing sessions (the same session) are, for example, various processes (communications) exchanged in a series of time periods such as connection to a server for browsing a recipe and disconnection of the connection.
It may be undesirable for the interest recipe to continue to increase as a standby recipe, as it causes an increase in the user's communication traffic. In such a case, in the case of this configuration, the second acquisition process is performed to execute the second acquisition process for acquiring the interest recipe only when the degree of interest greater than the maximum value is calculated. Is suppressed.
Therefore, since the process of acquiring the interest recipe is not executed, 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 viewing time, the interest level calculating unit 1 e presents the user with a plurality of recipes when calculating the level of interest based on the viewing time of the recipe. The browsing time in the state may not be used.
Thereby, the degree of interest can be calculated by a relatively light process of measuring the browsing time.
Therefore, acquisition of the interest recipe, which is the subsequent process, can be performed promptly.
In addition, by not using time zones presenting a plurality of recipes for calculation of the degree of interest, it is possible to more reliably determine a recipe in which the user is interested.

Furthermore, as described in the second example of the interest information based on the viewing time, the interest level calculation unit 1e may calculate the degree of interest based on the viewing time for the information amount of the recipe.
When a recipe with a large amount of information and a recipe with a small amount of information are mixed, it is inevitable that the browsing time of the recipe with a large amount of information is 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 properly calculated regardless of the amount of information of the recipe.

Then, as described in the first modification, the first acquisition process is executed in response to the fact that the number of already-acquired and unviewed recipes is less than the additional acquisition threshold, and the additional acquisition threshold is , 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 is provided to designate the timing for starting acquisition of the next condition matching recipe so that the user does not have to wait for acquisition of a recipe.
Therefore, it is considered that the additional acquisition threshold should be provided in consideration of different browsing speeds for each user.
According to this configuration, since the additional acquisition threshold is set according to the browsing speed of the user, it is possible to reduce the possibility of the user waiting for the acquisition of the recipe.
That is, since the additional acquisition threshold is set larger for a user who has a high browsing speed, a sufficient amount of recipe for the user is not yet viewed (waiting recipe), and a time for waiting for acquisition of a recipe occurs. It is possible to suppress the
On the other hand, since it is not necessary to set an unnecessarily large additional acquisition threshold for a user who has a slow browsing speed, it is not necessary to perform communication for which the waiting recipe is excessive for the user, and the amount of communication can be suppressed.

Furthermore, as described in the first example (FIG. 15) and the second example (FIG. 16) of the presentation priority setting process for the interest recipe, when presentation is possible such that a plurality of recipes can be viewed at one time, The presentation priority setting unit 1d may set the presentation priority for the interest recipe so as to be presented during the recipe being presented in the reconfiguration.
That is, the interest recipe acquired by taking into account the user's interest is presented among the plurality of recipes being browsed.
Therefore, the presentation reflecting the change of the user's interest etc. is performed immediately. Also, recipes which are likely to be of high interest to the user are presented on the screen without the user performing a scroll operation or the like.

In each of the above examples, a recipe is given as an example of content to be presented to the user, and a recipe management server 1 is given as an example of an apparatus for providing information to the user, but these are merely examples.
For example, various web pages may be content, and a search engine server for searching various web pages may provide information.
In addition, each piece of writing in a social network in which a plurality of users transmit information may be regarded as content, and the server device providing the function of searching for the writing may be a device providing the information.
Other examples of content and information providing devices (information processing devices) in various forms are conceivable.

Although the example of additionally acquiring the condition-conforming content (executing the first acquisition process) has been described on the condition that the number of unviewed content is less than the threshold, the additional acquisition is performed according to other conditions. It is also good.
For example, the next first acquisition processing may be executed on condition that the user continues to browse the contents after a predetermined time has elapsed since the previous acquisition of the condition-adapted content (or additional acquisition).
