Description

  The present invention relates to a technical field of an information processing apparatus, an information processing method, and a program for presenting a desired search target to a user by performing a search process.

In recent years, a service that accumulates information (for example, recipe information) by posting of a general user and the like and provides a search service using the accumulated information as a search target has been widely used.
In such an information providing service, a user can obtain desired information by designating various search conditions.
For example, Patent Literature 1 describes that rankings are dynamically switched when a parameter is changed by operating a knob provided for each parameter.

JP 2005-235139 A

The search result obtained by using the search service can be regarded as a kind of ranking indicating the degree of matching with the search condition. In that case, it is conceivable to employ the configuration described in Patent Document 1 as a configuration in which a search result obtained by the user changes when the user changes the parameter.
However, depending on how each parameter is changed, there is a possibility that a search result desired by the user cannot be obtained.
For example, a change mode in which all parameters are set to the maximum value may not only result in no or less search results, but also may fail to obtain a characteristic search target.
Therefore, the present invention provides an environment in which a feature of a search result desired by a user can be designated as a search condition by a simple operation, and the possibility that the user cannot obtain a desired search result can be reduced. The purpose is to:

An information processing apparatus according to the present invention includes an evaluation information management unit that manages a plurality of evaluation axes and evaluation values assigned to each evaluation target, and a search condition of the evaluation target by specifying the evaluation axis and the evaluation value. A presentation control unit that performs control for presenting a settable search condition setting unit, and information of an evaluation value before change and an evaluation value after change for a target evaluation axis that is a target of a change operation that changes the search condition. A change information acquisition unit to be acquired, and the target evaluation axis so that the total value of the evaluation values of all the evaluation axes does not change by a predetermined value or more according to a difference between the evaluation value before the change and the evaluation value after the change. A search condition adjustment unit that adjusts the search condition by changing an evaluation value of an adjustment evaluation axis that is at least one of the other evaluation axes, and performs a search process based on the adjusted search condition to perform the evaluation. Search processing to extract And parts, in which comprises a.
Adjustment to change the evaluation value of the adjustment evaluation axis is performed to suppress the change amount of the total value of the evaluation values of all the evaluation axes, so that the characteristic of the set value (evaluation value) set by the user on the target evaluation axis is easily displayed. Search conditions are set.

The presentation control unit of the information processing device described above specifies the initial value of the evaluation value and presents the search condition setting unit, and the initial value is a numerical value based on an action history of a user who searches for the evaluation target. It may be.
For example, if three levels of “cheap (evaluation value = 3)”, “normal (evaluation value = 2)”, and “high (evaluation value = 1)” can be specified for the evaluation axis of “price”, the user When searching for a search target, the presentation control unit specifies “3” as the initial value (default value) of the evaluation axis of “price” in response to specifying the evaluation value = 3 indicating that it is cheaper every time. The search condition setting means is presented in a state where is set.

The search condition adjustment unit of the information processing apparatus described above may perform the adjustment so that the magnitude relationship between the evaluation values between the adjustment evaluation axes does not collapse.
When the user specifies a condition for searching for an evaluation target, that is, when specifying an evaluation value, it is conceivable to specify a plurality of items. In this case, according to this configuration, the evaluation value of the evaluation axis is adjusted so that the magnitude relationship set for the evaluation axes other than the target evaluation axis set as the user's operation target does not collapse.

The search condition adjustment unit of the information processing device described above may perform the adjustment so as not to change the ratio of the evaluation value between the adjustment evaluation axes.
When the search condition is set by the user performing an operation to specify the evaluation values of multiple evaluation axes, the setting must be made before changing the evaluation value of the target evaluation axis that is the next operation target The relationship between the already evaluated evaluation axes is maintained.

The search condition adjustment unit of the information processing device described above may determine the adjustment evaluation axis based on a relationship between the adjustment evaluation axis and the target evaluation axis.
A positive correlation or a negative correlation may be found between the evaluation values of a plurality of evaluation axes. For example, when the user performs a change operation using the evaluation axis A as the target evaluation axis in the evaluation axes A and B where a negative correlation is seen, the evaluation axis B is selected as the adjustment evaluation axis and the evaluation axis A is selected. It is conceivable to increase or decrease the evaluation value of the evaluation axis B in a direction opposite to the performed operation of increasing or decreasing the evaluation value.
When the user performs a change operation with the evaluation axis C as the target evaluation axis in the evaluation axes C and D where a positive correlation is seen, the evaluation axis D is selected as the adjustment evaluation axis and the evaluation value of the evaluation axis C is selected. The adjustment is performed in the same direction as the increase / decrease operation performed on the evaluation axis, and the evaluation value is adjusted in a direction different from that of the evaluation value increase / decrease operation performed on the evaluation axis C as the adjustment evaluation axis for the other evaluation axes. I do.

The change information acquisition unit of the information processing device described above specifies a plurality of the change operations received during the search process from the presentation of the search condition setting unit as a series of change operations, and the search condition adjustment unit In the case where adjustment is performed in accordance with the latest change operation in the series of change operations, at least a part of the evaluation axes set as target evaluation axes in each of the series of change operations is removed from the adjustment evaluation axis and the adjustment is performed. May be performed.
For example, evaluation axes A to E that can be set by the user as search conditions are prepared, the user performs a change operation using the evaluation axis A as the target evaluation axis, and then performs a change operation using the evaluation axis B as the target evaluation axis. Is performed, instead of changing the evaluation value of the evaluation axis B according to the operation, another evaluation axis is used as an adjustment evaluation axis so that the total value does not change more than a predetermined value. At this time, according to this configuration, the evaluation axis A is removed from the adjustment evaluation axis in order to maintain the evaluation value specified by the user in the change operation.

In the information processing apparatus described above, the adjustment evaluation axis may be all evaluation axes other than the target evaluation axis.
Regardless of whether or not the user has previously performed a change operation, all evaluation axes other than the target evaluation axis are to be adjusted as adjustment evaluation axes. For example, if the user changes the evaluation value of the evaluation axis B, which is originally desired to be changed after the user accidentally changes the evaluation value of the evaluation axis A, the evaluation axis A is also set as the adjusted evaluation axis. Accordingly, it is possible to set search conditions according to the user's intention.

The search processing unit of the information processing device described above, when there is the evaluation axis whose evaluation value is equal to or more than a predetermined value in the adjusted search condition, the evaluation axis in which the evaluation value is equal to or more than a predetermined value. A search condition evaluation axis may be determined, and the search processing may be performed based on the label information assigned to the search condition evaluation axis.
For example, when the evaluation value that can be taken in each evaluation axis is 0 to 100, the predetermined value is 80, and the evaluation value of the evaluation axis A exceeds 80 after adjustment, the evaluation axis A is used as the search condition evaluation axis. It is determined. Further, when the label of the evaluation axis A is “saving”, a search process is performed so that a recipe having a high evaluation value of “saving” is extracted as a search result.

The search processing unit of the information processing apparatus performs an AND search based on label information assigned to each of the plurality of search condition evaluation axes in the search process when a plurality of the search condition evaluation axes exist. You may.
For example, if the evaluation values that can be taken in each evaluation axis are 0 to 100, the predetermined value is 80, and the evaluation values of the evaluation axis A and the evaluation axis B exceed 80 after adjustment, the evaluation axes A and B Is determined as the search condition evaluation axis. Further, when the label of the evaluation axis A is set to “conserving” and the label of the evaluation axis B is set to “healthy”, a recipe having a high evaluation value of “saving” and “healthy” is extracted as a search result. Search processing using the label information of the evaluation axis is performed.

The information processing method according to the present invention includes an evaluation information management step of managing a plurality of evaluation axes and evaluation values assigned to each evaluation target, and a search condition of the evaluation target by designating the evaluation axis and the evaluation value. A presentation control step of performing control for presenting a settable search condition setting unit, and information of an evaluation value before change and an evaluation value after change for a target evaluation axis targeted for a change operation for changing the search condition. The change information acquisition step to be acquired and the target evaluation axis so that the total value of the evaluation values of all the evaluation axes does not change by a predetermined value or more according to the difference between the evaluation value before the change and the evaluation value after the change. A search condition adjusting step of adjusting the search condition by changing an evaluation value of an adjusted evaluation axis which is at least one of the other evaluation axes; and performing a search process based on the adjusted search condition. A search processing step of extracting the value target, those with a.
With this information processing method, an environment is provided in which the features of the search result desired by the user can be specified as search conditions by a simple operation.
A program according to the present invention is a program for causing an information processing apparatus to execute processing executed as the information processing method. These programs realize the above information processing apparatus.

<3. Functional configuration of recipe management server>

As shown in FIG. 3, the recipe management server 1 includes a recipe management unit 1a, a change information acquisition unit 1b, a search condition adjustment unit 1c, a search processing unit 1d, and a presentation control unit 1e.

The recipe management unit 1a manages the recipe information by performing a process of storing the recipe information posted by the user in the recipe DB 51, a process of acquiring specific recipe information from the recipe DB 51, and the like.
The recipe information is information in which the recipe title, the ingredients used, the cooking method, the cooking utensil to be used, the category information to which the recipe belongs, the evaluation information assigned to the recipe, and the like are associated with the identification information identifying the user who posted the recipe information. It is.

  For example, a recipe of “vegetable curry” posted by a user is a recipe belonging to the category “curry rice”, and as used ingredient information, “potato”, “carrot”, “onion”, “broccoli”, “tomato” , "Spinach", seasonings (such as "salt" and "pepper"), and equivalents (such as "curry roux") are linked and stored as recipe information. In addition, as cooking utensils used when using recipes, for example, information such as "bowl" and "pot" is linked, and further, cutlery information such as utensils "spoon" used when eating is included. It may be linked. Further, an evaluation axis and an evaluation value are linked to the recipe information. The evaluation axis and the evaluation value are information used for the user to grasp what kind of recipe the recipe is and information used for searching for recipe information. “Evaluation axis” can be paraphrased as “evaluation item”.

Various examples can be considered for calculating the evaluation value. For example, it may be an evaluation value selected by the user who posts the recipe. Further, the evaluation value may be an evaluation value selected by a user who actually uses the posted recipe. Further, the evaluation value may be an evaluation value automatically given from information on the ingredients used or information on the cooking procedure.
Of course, the evaluation value may be determined by integrating these various information. Further, the evaluation value does not need to be fixed all the time after the numerical value is provided for the first time, and may be periodically re-evaluated and a new evaluation value may be provided.

  In addition, the recipe management unit 1a manages user evaluation information for the posted recipe. As the evaluation information, there is a created report including an impression and an evaluation value when the recipe is actually used. The creation report is managed in association with each recipe in the recipe DB 51.

When the user performs an operation for changing a search condition, the change information obtaining unit 1b performs a process of obtaining (receiving) information related to the change. In the following description, information relating to the change is simply referred to as “change information”.
This will be specifically described with reference to FIG.

The recipe management server 1 provides a search environment by presenting a search condition setting area 10 as shown in FIG. 4 to a user who searches for a recipe.
The search condition setting area 10 as shown in FIG. 4 is arranged at a predetermined location on a web page, for example, and is readable and operable by the user.

The search condition setting area 10 includes a tendency setting area 11 and a narrowing condition setting area 12.
The tendency setting area 11 is for specifying the tendency of the recipe to be searched, and includes, for example, a plurality of evaluation axes 13, 13,.

  Each evaluation axis 13 includes a knob 13a that indicates an evaluation value by position and a label 13b that indicates the type of the evaluation axis 13. The knob 13a displays a numerical value from 0 to 100 representing an evaluation value for the evaluation axis 13. The display mode of the numbers is an example, and may be displayed as 0 to 1, or may be set to a different numerical range for each evaluation axis 13. Of course, it may be represented by a binary value of 0 and 1, or a ternary value of 0, 1 and 2.

The user can change the tendency of the recipe to be searched by performing an operation of moving the knob 13a. In other words, the search conditions can be changed.
The change information acquisition unit 1b, for example, changes the evaluation value of the evaluation axis 13 to which the “saving” label has been assigned from “90” to “100”, and in response to the evaluation axis (object evaluation axis) ), And a process of acquiring the evaluation value (90) before the change and the evaluation value (100) after the change. Such processing may be realized, for example, by executing a program such as JS (JavaScript) added to web page data presented to the user.

One or more condition input fields 14, 14,... Are arranged in the refinement condition setting area 12. Each condition input column 14 is provided for setting conditions for further narrowing down recipes whose trends are specified using the tendency setting area 11. Each of the condition input fields 14 can input a character string, for example. FIG. 4 shows that a user who wants to search for a recipe using “spinach”, which is a surplus ingredient in the refrigerator, and who has a feeling that he wants to eat “curry and rice” has a narrowing-down condition. The example which was set is shown.
In the example shown in FIG. 4, a plurality of condition input fields 14 are provided so that a plurality of used ingredients can be designated. Furthermore, a configuration in which conditions for narrowing down the search results may be set in addition to the above may be possible. For example, there may be provided an input field in which an unused ingredient can be specified, or a radio button capable of selecting one of a main dish and a side dish may be provided.

  When the user changes the evaluation value of one evaluation axis 13 by operating the knob 13a, the search condition adjusting unit 1c executes a process of adjusting the evaluation value of another search axis 13. Such a process is performed, for example, so that the sum of the evaluation values of all the evaluation axes 13 is not too large or too small. Specific processing contents will be described later.

The search processing unit 1d executes a process of searching for a recipe according to a search condition specified by the user.
For example, a search button 15 is arranged in the search condition setting area 10 shown in FIG. By pressing the search button 15 after setting the search conditions, the user can cause the recipe management server 1 to execute a recipe search according to the set search conditions.

  Specifically, when the search button 15 is pressed under the search conditions shown in FIG. 4, the genre of the recipe is “curry and rice” and includes at least “spinach” as a used ingredient, and further includes “ A search process is performed to extract recipes that are “conservative” and “low-priced”.

The presentation control unit 1e performs a process of presenting a user with a web page in which search conditions can be set as shown in FIG. 4, a process of presenting a search result to the user, and the like. In addition, a process of transmitting web page data requested by the user terminal 3 is performed.
Therefore, the presentation control unit 1e may be a communication control unit that performs various communication processes performed by the recipe management server 1.

The recipe management server 1 may further include a user management unit that manages user information, an authentication processing unit that performs an authentication process for a user's login operation, and the like.

<4. DB>

[4-1. User DB]
The user DB 50 stores information of a user who receives a service provided by the recipe management server 1. For example, personal information such as a login password, name, age, gender, and mail address is stored in association with one user ID (Identification) that can identify one user. Further, preference information for each user may be stored. The preference information includes information on the user's favorite ingredients (preferred ingredients) and disliked ingredients (non-preferred ingredients) determined by the recipe management server 1 according to the user's behavior such as search and browsing of recipe information and dish information. The user's favorite ingredients (preferred ingredients) and disliked ingredients (non-preferred ingredients) determined by the recipe management server 1 based on posted information (text information, tag information, image information, etc.) related to the user. Further, the preference information may be information arbitrarily registered by the user.

[4-2. Recipe DB]
The recipe DB 51 is a DB that stores information on recipes posted by users. Specifically, for a recipe ID capable of identifying each recipe, a user ID for specifying a user who has posted the recipe, posted date and time information, category information to which the recipe belongs, and information on ingredients used in the recipe (such as the amount of ingredients) ), The recipe cooking procedure, image information such as a cooking image (image of a completed dish or an image of a cooking being cooked), evaluation information of the recipe, and actual use of the recipe (the cooking ) A creation report ID that identifies a creation report posted by another user is stored in association with the created report ID.
As described above, the evaluation information of the recipe may be set by the user who has posted the recipe, or may be set by the user who has used the recipe. Further, the evaluation information may be accumulated by both users. For example, initially, when a recipe is posted, an evaluation value for each evaluation axis is set by a user who has posted the recipe, and as the number of users who actually use the recipe increases, an evaluation value set by a user using the recipe is set. You may.

Further, URL (Uniform Resource Locator) information of the recipe detail page may be stored in association with the recipe ID.
Further, the recipe DB 51 stores information of a created report posted for each recipe. As the information of the creation report, text data indicating the contents of the report, an image of cooked food, a user ID capable of identifying a contributor, posting date and time information, and an evaluation value for each evaluation axis of the recipe are stored.

[4-3. Search DB]
The search DB 52 is a DB in which search results corresponding to search conditions are stored. More specifically, according to search conditions such as a dish name such as "curry rice" or "hamburger" or an ingredient name such as "mushroom" or "tomato", and further, according to search conditions such as an evaluation axis and an evaluation value, a plurality of Are associated and stored as search results.
For example, a search process is executed according to a search condition specified by the user, and a search result extracted as a result is associated with the search condition and stored in the search DB 52. By performing the linking in this manner, when a new search request is issued, the opportunity to present the search result using the previous search result without executing the search process increases.
Note that a search process based on the search condition may be periodically executed in advance, and the search result extracted as a result may be stored in the search DB 52 in association with the search condition.

[4-4. History DB]
The history DB 53 stores various histories related to user operations.
Specifically, for each operation performed by the user, the user ID, the history ID, the operation type, and the operation target (the recipe ID to be viewed in the case of “recipe viewing operation” or “recipe printing operation”, “web page Is an operation for browsing the web page, information for identifying the target web page, a “posting operation” is a posted recipe ID or a created report ID, and a “user information changing operation” is a change target. Item name), operation date and time, operation result (login permission / non-permission for “login operation”, change permission / prohibition for “user information change operation”, etc.) are stored.
Further, in the present embodiment, the operation of changing the search condition (hereinafter simply referred to as “change operation”) performed between the time when the search condition setting area 10 is presented to the user and the time when the search button 15 is pressed is performed. It is stored as a series of change operations. In the following description, an example in which processing is performed based on a series of change operations will be described.

[4-5. Web page DB]
The web page DB 54 stores data of various web pages provided by the recipe management server 1 to the user. Specifically, it is web page data such as a recipe search page, a special feature page, a search result page, a recipe detail page, and a user page. Web page data relating to the web page in which the search condition setting area 10 shown in FIG. 4 is arranged is also stored in the web page DB 54.
As the web page data, URL (Uniform Resource Locator) information of the web page and arrangement information of an object (image, text, banner, etc.) arranged on each web page are stored. The arrangement information is information in which the arrangement mode (position, size, color, etc.) of each object on the web page is described.
The information stored in the web page DB 54 may be stored in a structured document file such as HTML (Hyper Text Markup Language) or XHTML (Extensible HyperText Markup Language).

[4-6. DB Mode]
These DBs (user DB 50, recipe DB 51, search DB 52, history DB 53, web page DB 54) are in any form as long as each information processing device constituting the recipe management server 1 is accessible as needed. It may be realized by. For example, all of the DBs (user DB 50, recipe DB 51, search DB 52, history DB 53, web page DB 54) may be formed in a storage unit in the same system as the recipe management server 1, or each DB (user DB 50, recipe Part or all of the DB 51, the search DB 52, the history DB 53, and the web page DB 54) may be provided in a computer system such as a separate or remote location. Of course, it is not necessary that each DB (user DB 50, recipe DB 51, search DB 52, history DB 53, web page DB 54) be formed in one device (for example, one HDD or the like). Further, each of the DBs (the user DB 50, the recipe DB 51, the search DB 52, the history DB 53, and the web page DB 54) does not need to be configured as one DB. For example, information stored in 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 storing preference information on recipes). Each of the DBs described below (user DB 50, recipe DB 51, search DB 52, history DB 53, web page DB 54) is merely an example of a storage unit of information related to the processing of the embodiment in the form of one DB. Absent.

<5. Processing Flow>

Various processes executed by the recipe management server 1 will be described.

[5-1. Overall flow]
First, with reference to FIG. 5, each process executed by the recipe management server 1 and the user terminal 3 and data transmitted and received between both information processing terminals will be described.

  When the user performs an operation of requesting a web page for logging in to a recipe site in order to enjoy various services provided by the recipe management server 1, the user terminal 3 logs in in step S101 in response to the operation. Execute screen information request processing. With this process, the user terminal 3 requests the web page data as the login screen from the recipe management server 1.

Recipe management server 1 having received the request for the login screen information executes a process of acquiring login screen information (web page data) from web page DB 54 and transmitting it to user terminal 3 in step S201.
Thereby, for example, a web page corresponding to the login screen information (web page data) of the recipe site received from the recipe management server 1 is displayed on the user terminal 3.
At this time, the recipe management server 1 may store the fact that the login screen is displayed on the user terminal 3 as a history (that is, a browsing history of the login screen).

  Next, in step S102, the user terminal 3 executes a login information transmission process of transmitting login information (user ID and login password) input by a user operation to the recipe management server 1.

In response to the login information being transmitted from the user terminal 3 to the recipe management server 1, the recipe management server 1 executes an authentication process in step S202, executes a process of storing a login history in step S203, and executes step S204. Executes an authentication result notifying process.
Specifically, the recipe management server 1 compares the user ID and the password input on the user terminal 3 with the information stored in the user DB 50 to determine whether or not the user can log in, and stores the log in / out information as a history. The information is stored in the history DB 53 as information, and the login availability information is notified to the user terminal 3 as an authentication result. The authentication result may be transmitted to the user terminal 3 and the web page data of the top page of the recipe site may be transmitted. Thereby, the user is authenticated and the top page of the recipe site is displayed on the user terminal 3.

  Note that a series of flows illustrated in FIG. 5 illustrates a case where it is determined that the login is permitted in the authentication processing in step S202. If it is determined in step S202 that the login is impossible, the user terminal 3 executes the processing of step S102 again in response to the user's login information input operation, and the recipe management server 1 executes the processing of step S202 in response to this.

  Next, when the user performs an operation for displaying a search condition setting screen for setting a search condition in order to search for a recipe, the user terminal 3 changes the search condition setting screen to a recipe management server in step S103. 1 is performed. By this processing, a search condition setting screen request is transmitted from the user terminal 3 to the recipe management server 1.

In response to the request, the recipe management server 1 acquires search condition setting screen information (web page data) from the web page DB 54 and executes a process of transmitting the information to the user terminal 3 (step S205).
By this processing, for example, a web page (for example, a web page shown in FIG. 4) on which a search condition for searching for a recipe desired by the user can be set is displayed on the user terminal 3 from the recipe management server 1.

When the user performs an operation of changing the search condition, the user terminal 3 executes a process of receiving the change operation in step S104 and transmitting the change information to the recipe management server 1. This processing is executed, for example, by the user sliding the knob 13a shown in FIG.
The change information transmitted to the recipe management server 1 includes information for specifying an evaluation axis (hereinafter, referred to as a “target evaluation axis”) subjected to the user's change operation, an evaluation value before the change, and an evaluation after the change. Value information.
However, the evaluation value before the change is the initial value of the evaluation value (for example, 50 which is the middle value of 0 to 100) or the evaluation value after the change specified by the change operation performed before that. Since the information can be already known by the recipe management server 1, the information need not be received from the user terminal 3.
Further, instead of the evaluation value after the change, a change value, that is, a value (that is, a change amount) that can specify how much the user has moved the evaluation value by the change operation may be transmitted.

  The timing at which the change information is transmitted to the recipe management server 1 is, for example, the timing at which the slide operation on the selected knob 13a is completed, that is, the timing at which the drag operation (the operation of sliding the knob 13a) is completed. Alternatively, the timing may be provided at regular intervals, including during the drag operation.

Recipe management server 1 that has received the change information executes search condition adjustment processing in step S206. This process is a process for preventing the search condition from being changed to an inappropriate one by the change of the evaluation value performed by the user.
The change to an inappropriate one is, for example, a change to a search condition that significantly reduces search results, or a change in all evaluation values to a maximum value (100 in the example of FIG. 4). It is shown that.

Specifically, in step S206, a process of automatically adjusting the evaluation values of the other evaluation axes according to the change operation performed by the user is performed. This prevents the search condition from becoming inappropriate.
The detailed processing content of step S206 will be described later.

The recipe management server 1 transmits the adjustment information to the user terminal 3 by executing the processing of step S206. As the adjustment information, adjustment information on an evaluation axis that has been adjusted (hereinafter, referred to as an “adjustment evaluation axis”) is transmitted to the user terminal 3. Thereby, the adjusted evaluation value is presented on the search condition setting screen displayed on the user terminal 3.
The user terminal 3 performs the process of step S104 each time the user performs the change operation, and the recipe management server 1 performs the process of step S206 accordingly.
By executing these series of processes one or more times, the user can set search conditions on the search condition setting screen.

  Subsequently, when the user presses the search button 15 according to the determined search condition, the user terminal 3 executes a search operation accepting process of step S105. In this process, the determined search condition is transmitted to the recipe management server 1 and the execution of the search process according to the search condition is requested to the recipe management server 1.

Receiving the search request, the recipe management server 1 executes a search process in step S207, and extracts a recipe according to the search condition specified by the user as a search result.
In the search process, for example, a process of searching for a recipe based on search conditions set in a radar chart as shown in FIG. 4 is executed. For example, each recipe managed by the recipe management server 1 has information capable of constructing a radar chart shown in FIG. 4 for each recipe, and a recipe whose radar chart shape is similar to a search condition is extracted as a search result. I do.

The recipe in which the shape of the radar chart is similar to the search condition may be, for example, a recipe having a similar shape, or an evaluation axis having a prominent evaluation value (in FIG. 4, an evaluation axis labeled “saving” or “ An evaluation axis labeled “low price” may be the same recipe. Conversely, an evaluation axis with a low evaluation value (such as an evaluation axis labeled “luxury” in FIG. 4) may be the same recipe.
Further, by using information obtained by adding the difference between each evaluation value in the search condition and the recipe to be searched, it may be determined whether the recipe is similar or the variance value is calculated from the difference between each evaluation value. Thereby, the determination may be made.
In step S207, a search result associated with the search condition set by the user may be obtained from the search DB 52, so that the search result may be used as a substitute for the search process.

  Next, the recipe management server 1 executes a process of storing the information of the search history in the history DB 53 in step S208, and transmits the information of the search result to the user terminal 3 in step S209. The information transmitted to the user terminal 3 is, for example, search result screen data (web page data) in which search results are arranged.

The user terminal 3 performs a process of displaying a search result screen on the user terminal 3 according to the received search result screen data. This allows the user to browse the recipe information extracted according to the search conditions set by the user.
After the process of step S106, the user selects one of the recipes displayed as the search results, performs an operation of displaying a detailed screen, or displays other search results without being satisfied with the search results. It is possible to perform an operation for requesting a search condition setting screen again in order to set search conditions for obtaining.
The user terminal 3 executes an appropriate process in response to such an operation, and the recipe management server 1 executes an appropriate process in response to various requests from the user terminal 3. A detailed description of these processes will be omitted.

[5-2. Search condition adjustment processing]
An example of the search condition adjustment processing shown in step S206 of FIG. 5 will be described with reference to FIG.
In step S301, the recipe management server 1 executes a process of acquiring change information. As described above, the change information is information for specifying the target evaluation axis that has been the target of the user's change operation, and information on the evaluation value of the target evaluation axis before and after the change.

In step S302, the recipe management server 1 executes a difference calculation process.
A specific example will be described.
FIG. 7A shows the search condition setting area 10 arranged on the search condition setting screen presented to the user. In this example, the evaluation values of the six evaluation axes 13 can be specified as search conditions. The six evaluation axes 13 are an evaluation axis 13A representing a “short-time” degree, an evaluation axis 13B representing a “health” degree, an evaluation axis 13C representing a “easy” degree, an evaluation axis 13D representing a “luxury” degree, The evaluation axis 13E indicates a "low price" degree, and the evaluation axis 13F indicates a "fullness" degree. The evaluation shaft 13A includes a knob 13Aa and a label 13Ab. The evaluation shaft 13B includes a knob 13Ba and a label 13Bb. The evaluation shaft 13C includes a knob 13Ca and a label 13Cb. The evaluation shaft 13D includes a knob 13Da and a label 13Db. The evaluation shaft 13E includes a knob 13Ea and a label 13Eb. The evaluation shaft 13F includes a knob 13Fa and a label 13Fb.

FIG. 7B is a diagram illustrating a state in which the user has performed a change operation to change the evaluation value of the evaluation axis 13A from “50” to “100” from the state illustrated in FIG. 7A.
In the state shown in FIG. 7A, the total evaluation value obtained by adding the evaluation values of the evaluation axes 13A to 13F is “300”. In the state shown in FIG. 7B, the total evaluation value is “350”.
Therefore, in the difference calculation process of step S302, “50” obtained by subtracting the total evaluation value “300” before the change from the total evaluation value “350” after the change is calculated as the difference value.

Subsequently, in step S303, the recipe management server 1 executes a process of calculating an adjustment amount.
The adjustment amount is a numerical value calculated to prevent the total evaluation value from changing by a predetermined value or more.
For example, when the predetermined value is “0”, it means that the adjustment amount is calculated so that the total evaluation value before and after the change becomes the same value. Therefore, in the above example, since the total evaluation value before the change is “300”, the adjustment amount is calculated so that the total evaluation value after the change becomes “300”. Since the total evaluation value after the change is set to “350” by the operation of the user, the adjustment amount is calculated to be “−50”.
This means that the evaluation values of the evaluation axes (evaluation axes 13B to 13F) other than the target evaluation axis (evaluation axis 13A) are subtracted by "50" by automatic adjustment.

In step S304, the recipe management server 1 determines which evaluation axis of the evaluation value is to be automatically adjusted. The evaluation axis targeted for automatic adjustment is referred to as “adjustment evaluation axis”.
Several examples can be given for the determination of the adjustment evaluation axis.

Subsequently, in step S305, the recipe management server 1 performs a process of calculating an adjusted evaluation value for each adjustment evaluation axis.
Some examples of the processes in steps S304 and S305 will be described with reference to the drawings.

First, a first example will be described with reference to FIG. 8A.
The first example is an example in which all evaluation axes except the target evaluation axis are used as adjustment evaluation axes. That is, five evaluation axes 13B to 13F are set as adjustment evaluation axes (step S304).
Further, in step S305, a process of uniformly adding or subtracting the same value to the adjustment evaluation axis is performed. That is, since the adjustment amount “−50” is achieved using the five adjustment evaluation axes, the adjustment amount of the evaluation value per adjustment evaluation axis may be set to “−10”. Therefore, the evaluation axis 13B achieves the adjustment amount “−10” by changing from “30” to “20”. The evaluation axis 13C achieves the adjustment amount “−10” by changing from “50” to “40”. The evaluation axis 13D achieves the adjustment amount “−10” by changing from “70” to “60”. The evaluation axis 13E achieves the adjustment amount “−10” by changing from “30” to “20”. The evaluation axis 13F achieves the adjustment amount “−10” by changing from “70” to “60”.

  The recipe management server 1 transmits the adjustment information to the user terminal 3 in step S306. The information transmitted to the user terminal 3 may be, for example, a numerical value after adjustment or a numerical value indicating the adjustment amount for each evaluation axis. Taking the evaluation axis 13B as an example, a value of “20” may be transmitted as an adjusted numerical value, or a value of “−10” may be transmitted as an adjustment amount of the evaluation axis 13B.

Another example of the process in step S305 will be described with reference to FIG. 8B.
After setting all evaluation axes other than the target evaluation axis as the adjustment evaluation axes in step S304, the recipe management server 1 calculates the adjusted evaluation values for each adjustment evaluation axis in step S305. The evaluation value is calculated such that the evaluation value after the adjustment with respect to the evaluation value before the adjustment of the axis has a fixed ratio.

  Specifically, the sum of the evaluation values of the evaluation axes 13B to 13F shown in FIG. 7B is “250”, and the adjustment amount is “−50”. Therefore, by adjusting “250” to 80% (ie, subtracting 20%), the adjustment amount “−50” can be achieved.

This can be realized by subtracting 20% of each evaluation value for each of the evaluation axes 13B to 13F. That is, with respect to the evaluation axis 13B, 20% is subtracted from the evaluation value “30” before the adjustment to obtain “24”. For the evaluation axis 13C, 20% is subtracted from the evaluation value “50” before adjustment to “40”. With respect to the evaluation axis 13D, 20% is subtracted from the evaluation value "70" before adjustment to be "56". With respect to the evaluation axis 13E, 20% is subtracted from the evaluation value “30” before the adjustment, and is set to “24”. With respect to the evaluation axis 13F, 20% is subtracted from the evaluation value "70" before adjustment to be "56".
Thus, the total value of the adjusted evaluation values on the evaluation axes 13B to 13F is set to “200 (= 24 + 40 + 56 + 24 + 56)”. In other words, the adjustment amount “−50” is achieved.

  Note that, in the above example, an example in which the “predetermined value” used in the calculation of the adjustment amount in step S303 is “0”, but another value may be used. For example, the predetermined value may be “20”. In this case, if the difference between the total evaluation value before the change and the total evaluation value after the change is “less than 20”, the automatic adjustment is unnecessary. For example, if the total evaluation value before the change is “300” and the total evaluation value after the user's change operation is “310”, no change of a predetermined value (= 20) or more has occurred. The adjustment amount calculated in step S303 is set to “0”, and the execution of each processing in steps S304 to S305 is omitted. In the transmission processing in step S306, it is sufficient that notification that adjustment is unnecessary can be made. For this purpose, information of an unadjusted evaluation value may be transmitted as an adjusted evaluation value, and the adjustment amount may be changed. Information indicating “0” may be transmitted, or information indicating that no adjustment is performed may be transmitted.

In addition, regarding calculating the adjustment amount so that the “evaluation value before change and the evaluation value after change are equal to or more than a predetermined value”, when the user displays the “evaluation value before change” on the search condition setting screen, May be the evaluation values in the initial state of each evaluation axis (ie, the state in which the user has not performed the operation of changing the evaluation value after displaying the search condition setting screen).
For example, when the user performs a change operation of adding the evaluation value “10” to the evaluation axis 13A, the change operation does not change the evaluation value before and after the change by a predetermined value (= 20) or more, so the adjustment amount is not changed. It will be "0". However, when such a change operation of adding the evaluation value “10” is performed continuously, the automatic adjustment of the evaluation value is performed despite the evaluation values of all the evaluation axes 13A to 13F being “100”. A situation that does not occur may occur. That is, there is a possibility that an inappropriate search condition such that the search result is extremely small can be set.
Therefore, by making the “evaluation value before change” the “evaluation value in the initial state”, according to the previous example, the “initial value” is obtained when a change operation to add the evaluation value “10” is performed twice. The evaluation value changes from the "evaluation value in the state" to a predetermined value (= 20) or more, and the evaluation value is automatically adjusted appropriately.
This can prevent the search condition from becoming inappropriate.

Note that the state shown in FIG. 7B shows a state in which only the change by the user's change operation is reflected in the state (initial state) shown in FIG. 7A. When the result of the search condition adjustment process executed by the recipe management server 1 is reflected in the search condition setting area 10 at substantially the same time that the change due to the change operation is reflected in the search condition setting area 10, FIG. 7B may be presented to the user for a very short time, or the state shown in FIG. 7B may not be presented to the user. In that case, the search condition setting area 10 presented to the user in response to the user performing the change operation is in the state shown in FIG. 8A or the like.

[5-3. Second example of search condition adjustment processing]
In the second example of the search condition adjustment processing and a third example described later, the adjustment of the evaluation value is performed by focusing on the relationship between the evaluation axes.
The state shown in FIG. 9A is an example in which the evaluation value is adjusted in consideration of the negative correlation between the evaluation axes. The state shown in FIG. 9B is an example in which the evaluation value is adjusted in consideration of both the positive correlation and the negative correlation between the evaluation axes.

Each process executed by the recipe management server 1 in the second example of the search condition adjusting process will be described with reference to FIG.
Note that, in the second example of the search condition adjustment processing, the recipe management server 1 performs the search in response to the user performing a change operation for changing the search condition to the state illustrated in FIG. 7B in the state illustrated in FIG. 7A. The condition is automatically adjusted to change to the state shown in FIG. 9A.

The recipe management server 1 performs each processing of steps S301 to S303. This process is similar to the process described with reference to FIG. 6, and will not be described in detail.
After calculating the adjustment amount as “−50”, in step S307, the recipe management server 1 sets an evaluation axis having a negative correlation with the target evaluation axis as the adjustment evaluation axis. That is, the target evaluation axis and the adjustment evaluation axis selected here have a negative correlation.

The negative correlation will be specifically described.
For example, in the example shown in FIG. 9A, the evaluation axis 13A is set as the target evaluation axis, and the evaluation axis 13D is set as the adjustment evaluation axis. That is, there is a negative correlation between the evaluation axis 13A in which the label 13Ab is set to “short time” and the evaluation axis 13D in which the label 13Db is set to “luxury”.
Whether or not there is a negative correlation between the evaluation axes is determined based on the tendency seen in the recipe group managed by the recipe management server 1. Therefore, in the example shown in FIG. 9A, many recipes with a short cooking time have a poor sense of quality, and many high-quality recipes do not require a short cooking time. The axis 13A and the evaluation axis 13D are determined to have a negative correlation.

In step S305, the recipe management server 1 calculates the adjusted evaluation value of the adjustment evaluation axis (that is, the evaluation axis 13D). In the process of step S303, since the adjustment amount is calculated as “−50”, the adjusted evaluation value of the adjustment evaluation axis is calculated as “20” obtained by subtracting 50.
As a result, it is possible to avoid a state in which the evaluation values of the contradictory evaluation axes are mutually the maximum value (= 100). That is, it is possible to prevent the search condition from becoming inappropriate.
Subsequently, the recipe management server 1 transmits the adjustment information in step S306.

[5-4. Third example of search condition adjustment processing]
A third example of the search condition adjustment processing will be described with reference to FIGS. 9B and 11.
Note that, in the third example of the search condition adjustment process, the recipe management server 1 performs the search in response to the user performing a change operation for changing the search condition to the state illustrated in FIG. 7B in the state illustrated in FIG. 7A. The condition is automatically adjusted to change to the state shown in FIG. 9B.

The recipe management server 1 calculates the adjustment amount based on the change information by executing the processes of steps S301 to S303. The adjustment amount is set to “−50”.
Next, in step S308, the recipe management server 1 sets an evaluation axis having a positive correlation with the target evaluation axis as a first adjustment evaluation axis.
This will be specifically described with reference to FIG. 9B. In the example shown in FIG. 9B, it is assumed that the evaluation axis 13A and the evaluation axis 13C have a positive correlation. That is, there is a positive correlation between the evaluation axis 13A in which the label portion 13Ab is set to “short time” and the evaluation axis 13C in which the label portion 13Cb is set to “easy”. This means that many recipes with a short cooking time have a high evaluation value with ease, and many recipes with a short cooking time have a low evaluation value with ease. I have.

  Such positive correlation information and negative correlation information between evaluation axes may be stored in any of the DBs used by the recipe management server 1.

In step S309, the recipe management server 1 performs a process of calculating an adjusted evaluation value of the first adjustment evaluation axis (the evaluation axis 13C). In the example shown in FIG. 9B, the evaluation value of the target evaluation axis (evaluation axis 13A) has been increased by “50” from “50” to “100”, so that the first adjustment evaluation axis is also increased by “50”. (Evaluation value “50” to evaluation value “100”).
There are several examples of the processing in step S309. For example, the evaluation value of the first adjustment evaluation axis may be adjusted so that the increase rate of the target evaluation axis is equal to the increase rate of the first adjustment evaluation axis.

In step S310, the recipe management server 1 sets an evaluation axis having a negative correlation with the target evaluation axis as the second adjustment evaluation axis. As in the previous example, the evaluation axis where a negative correlation is observed is the evaluation axis 13D. That is, the second adjustment evaluation axis is the evaluation axis 13D.
Next, in step S311, the recipe management server 1 calculates an adjusted evaluation value of the second adjustment evaluation axis (evaluation axis 13D). In this process, if the adjustment amount (= −50) calculated in step S303 can be achieved, the recipe management server 1 performs a process of transmitting adjustment information to the user terminal 3 in step S306, and performs a search condition adjustment process. To end.

  In the example shown in FIG. 9B, since the value is increased by “50” in the first adjustment evaluation axis, it is necessary to subtract “100” from the second adjustment evaluation axis in order to achieve the adjustment amount “−50”. Since the evaluation value of the second adjustment evaluation axis before the adjustment is “70”, the adjustment amount “−50” cannot be achieved. In that case, it is preferable to execute each processing shown in FIG. 12 after the processing in step S311.

After the processing in step S311, the recipe management server 1 determines in step S312 whether adjustment of another evaluation axis is necessary. The other evaluation axes are other evaluation axes (evaluation axes 13B, 13E, 13F) excluding the target evaluation axis (evaluation axis 13A), the first evaluation axis (evaluation axis 13C), and the second evaluation axis (evaluation axis 13D). ).
In FIG. 9B, the adjustment amount for the first adjustment evaluation axis is “+50”, and the adjustment amount for the second adjustment evaluation axis is “−70”. Since the total adjustment amount on the first adjustment evaluation axis and the second adjustment evaluation axis is “−20”, there is a deviation from the adjustment amount “−50” calculated in step S303.
In such a case, it is determined in the determination processing in step S312 that adjustment of another evaluation axis is necessary.

In step S313, the recipe management server 1 sets an evaluation axis not selected as the adjustment evaluation axis (that is, the evaluation axes 13B, 13E, and 13F) as a new adjustment evaluation axis, and in step S314, sets a new adjustment evaluation axis. Calculate the adjusted evaluation value.
In the example of FIG. 9B, the adjustment value “−50” calculated in step S303 can be achieved by changing the evaluation value to “−10” for each new adjustment evaluation axis.
Therefore, the evaluation value of the evaluation axis 13B is adjusted from “30” to “20”, the evaluation value of the evaluation axis 13E is adjusted from “30” to “20”, and the evaluation value of the evaluation axis 13F is set to “70”. To "60".
In summary, as for each evaluation value after executing the search condition adjustment processing, the evaluation axis 13A is set to “100”, the evaluation axis 13B is set to “20”, the evaluation axis 13C is set to “100”, and the evaluation axis 13D is set to “100”. It is set to "0", the evaluation axis 13E is set to "20", and the evaluation axis 13F is set to "60". The total evaluation value of each evaluation axis is “300”, which is equal to the total evaluation value before the user's change operation.

Finally, the recipe management server 1 transmits the adjustment information to the user terminal 3 in step S306, and ends the series of processes illustrated in FIGS. In addition, even when it is determined in step S312 that adjustment of another evaluation axis is unnecessary, the recipe management server 1 finally transmits the adjustment information to the user terminal 3 in step S306, and ends the search condition adjustment processing.
Note that each process illustrated in FIG. 12 may be executed after the process in step S305 in FIG.

[5-5. Fourth example of search condition adjustment processing]
A fourth example of the search condition adjustment processing will be described with reference to FIG.
In the fourth example of the search condition adjustment processing, a plurality of change operations performed from when the search condition setting screen is presented to the user until the search request is received are treated as a series of change operations.

The recipe management server 1 calculates the adjustment amount according to the search condition changing operation performed by the user by executing the processes of steps S301 to S303.
Subsequently, in step S315, the recipe management server 1 determines whether a page transition has occurred since the previous change operation.
If no page transition has occurred since the previous change operation, the recipe management server 1 executes the current change operation (the change operation for which change information was acquired in step S301) in a series of subsequent change operations. Is determined and stored.

A specific example will be described. After the search condition setting screen in which the state shown in FIG. 7A is set to the initial state is presented, it is assumed that the user wants to search for a healthy cooking recipe with a short cooking time. In that case, the user operates the knob 13Aa of the search axis 13A to perform a change operation to increase the evaluation value from “50”, and then operates the knob 13Ba of the search axis 13B to obtain the evaluation value. It is conceivable to perform a change operation to increase the value from “30”.
Here, a change operation on the search axis 13A is referred to as a "first change operation", and a change operation on the search axis 13B is referred to as a "second change operation". It is considered that it is not preferable for the user that the evaluation value set by the user in the first change operation is adjusted (changed) by the search condition adjustment processing executed in response to the second change operation.
This example is to avoid such a state.

  If the current change operation is a series of change operations following the previous change operation, in step S317, the recipe management server 1 sets an evaluation axis other than the target evaluation axis in the series of change operations as an adjustment evaluation axis. That is, in the above example, the evaluation axis 13A, which is the target evaluation axis of the first change operation, and the evaluation axis 13B, which is the target evaluation axis of the current change operation (second change operation), are removed, and the other evaluation axes are removed. Is set as the target evaluation axis.

  Subsequently, in step S305, the recipe management server 1 calculates an adjusted evaluation value for each adjustment evaluation axis. This process is the same as the process described with reference to FIG. However, instead of the process shown in FIG. 7, various processes described in FIGS. 10 to 12 may be executed.

  After calculating the adjusted evaluation value of the adjustment evaluation axis, the recipe management server 1 transmits the adjustment information to the user terminal 3 in step S306.

If it is determined in step S315 that the page has changed from the previous change operation, that is, if the current change operation is the first change operation performed after the search condition setting screen is presented to the user, the recipe management server In step S318, information regarding the current change operation is stored as a new change operation in step S318, and all evaluation axes other than the target evaluation axis can be set as adjustment evaluation axes in step S304. Of course, some of them may be used as the adjustment evaluation axis.
Next, the recipe management server 1 executes each processing of steps S305 and S306.

  By executing each process shown in FIG. 13, the adjustment axis once changed by the user is excluded from the evaluation axis to be adjusted, and the user's set value is retained.

In addition, when all the evaluation axes that can be changed are set as the target evaluation axes by performing a series of change operations, there is a possibility that there is no evaluation axis that can be set as the adjustment evaluation axis. In this case, for example, it is conceivable that an adjustment evaluation axis other than the target evaluation axis in the previous change operation and the current change operation is used. As a result, the target evaluation axis of the change operation performed at the beginning of the series of change operations can be set as the adjustment evaluation axis, and an inappropriate search condition that maximizes all the evaluation values can be set. Can be prevented from being set.

[5-6. Search query setting process]
In each of the above-described examples, an example of searching for a recipe having a similar radar chart shape in the search processing of step S207 in FIG. 5 has been described, but other examples are also conceivable.
This will be specifically described with reference to FIG.

In this example, a search query is set according to each evaluation value.
In step S401, the recipe management server 1 performs a process of specifying at least a part of the evaluation axis as a search condition evaluation axis based on the obtained search condition.
The search condition evaluation axis is an evaluation axis in which text information posted on the label section 13b is used as a search query. For example, in the example shown in FIG. 8A, the evaluation axis 13A (evaluation value “100”) having the highest evaluation value compared to the other evaluation axes is set as the search condition evaluation axis. In specifying the search condition evaluation axis, a threshold may be used. For example, when the threshold is set to “80”, an evaluation axis having an evaluation value equal to or larger than the threshold may be specified as the search condition evaluation axis.

  After specifying the search condition evaluation axis, the recipe management server 1 acquires the label information of the search condition evaluation axis in step S402. In the example of FIG. 8A, a character string “short time” which is text information displayed on the label unit 13Ab is acquired as label information.

  In step S403, the recipe management server 1 executes a process of generating a search query. In this process, a search query including the label information acquired in step S402 is generated. For example, a character string “short time” extracted from FIG. 8A and narrowing conditions (for example, genre information “curry rice” and used food information “spinach”) shown in FIG. 4 are used for the search query. Specifically, a character string of “curry rice spinach short time” is generated as a search query.

  The recipe management server 1 executes the search processing of step S207 using the generated search query. Thereby, the search for the recipe information according to the search condition set by the user is performed.

  Note that a plurality of search condition evaluation axes may be specified in the process of step S401, and a plurality of label information may be acquired in step S402. In that case, in step S403, a search query for performing an AND search such as "short term easy" is generated.

When specifying the search condition evaluation axis in step S401, the evaluation axis with the lowest evaluation value may be set as the search condition evaluation axis. In the example shown in FIG. 8A, the evaluation axis 13B and the evaluation axis 13E are used as search condition evaluation axes. In that case, the character strings "healthy" and "low price" are extracted in step S402, and the character strings "healthy" and "low price" are included in generating the search query in step S403. It is conceivable to search for no recipe. That is, a search condition evaluation axis is used to obtain a character string used for a so-called NOT search.
Of course, both the evaluation axis with the higher evaluation value and the evaluation axis with the lower evaluation value may be specified as the search condition evaluation axis.

[5-7. Initial evaluation value determination processing]
When the search condition setting screen is presented to the user, the radar chart displayed in the trend setting area 11 of the search condition setting area 10 arranged in the screen has the initial value (initial evaluation value) of each evaluation value. The state is set (initial state). Here, an example in which each initial evaluation value is determined according to the user will be described with reference to FIG.

The recipe management server 1 acquires the history information of the user in step S501.
The user's history information may be, for example, a recipe browsing history, a recipe usage history, or a user's browsing history of another web page. Further, it may be a history of search conditions specified by the user, or may be information such as products and ingredients purchased by the user. The use of a recipe may be estimated based on a creation report posted by a user who has actually created a dish using the recipe, or may be estimated based on the length of time for viewing the recipe.

As an example, the evaluation value of each evaluation axis set by the user for searching the previous recipe is acquired as the history information.
Subsequently, in step S502, the recipe management server 1 sets an initial evaluation value.
When each evaluation value set at the time of the previous recipe search is obtained, the obtained evaluation value is set as an initial evaluation value as it is.

  Note that the evaluation values set in the latest plurality of recipe searches may be acquired as history information, and the average of the acquired evaluation values may be used in calculating the initial evaluation values.

As another example, the user may acquire the history information searched for “easy recipe” and set the initial evaluation value of the evaluation axis 13C of “easy” to a higher value accordingly.

<6. Various modifications>

[6-1. Modification 1]
A modified example in the search query setting process will be described.
In the process of specifying the search condition evaluation axis in step S401 shown in FIG. 14, the evaluation axis for which the user has set the evaluation value, that is, the target evaluation axis may be considered.
For example, in the example illustrated in FIG. 9B, the evaluation value of the evaluation axis 13A has been changed to “100” by the user's changing operation. That is, it can be inferred that the user has an intention to search for a recipe that can be cooked in a “short time”.
On the other hand, the search axis 13C has the evaluation value adjusted to “100” by the processing of steps S308 and S309 shown in FIG.

  In view of the difference between the evaluation axis 13A and the evaluation axis 13C, it can be seen that a search query including only “easiness” is not preferable. Also, a search query including “short time” is likely to be a search query that meets the user's intention.

Therefore, in the processing of step S401 shown in FIG. 14, at least the target evaluation axis which is the target of the user's change operation and which has a high evaluation value (or has a low evaluation value) is set as a search condition evaluation axis. It is desirable to specify. In addition, among the adjustment evaluation axes, an evaluation axis having a higher (or lower) evaluation value may be used as a search condition evaluation axis.
This makes it possible to generate a search query that matches the user's search intention.

[6-2. Modification 2]
In each of the above-described examples, each time the user's change operation is completed, the search condition adjustment processing illustrated in FIG. 6 and the like is performed. As another conceivable example, the search condition adjusting process is performed periodically (for example, every 100 msec) even while the user is performing the change operation, in other words, while the user is moving the knob 13a. May be performed. The user can know in real time how the evaluation values of the other evaluation axes change according to his / her change operation, and can perform an appropriate change operation in consideration of the change.

[6-3. Modification 3]
A modified example of the radar chart displayed in the trend setting area 11 of the search condition setting area 10 will be described with reference to FIG.
The format of the graph or figure displayed in the trend setting area 11 may be a line graph as shown in FIG. 16A or a bar graph.
Further, as shown in FIG. 16B, a label portion and an input field in which an evaluation value can be input may be arranged.
Further, it may be like a pie chart.
Such a display mode makes it possible to clarify the magnitude relationship between the evaluation values between the evaluation axes, so that the user can easily understand what the search condition set by himself / herself is. Become.

[6-4. Modification 4]
When performing the search condition adjustment process, it may be performed while determining whether or not a certain number or more of search results can be obtained.
For example, when the user performs an operation of changing the search condition from the state illustrated in FIG. 7A to the state illustrated in FIG. 7B, consider a case where the search condition adjustment processing is performed to adjust the search condition to the state illustrated in FIG. 9B. .
At this time, the search processing to be performed when the state is adjusted to the state illustrated in FIG. 9B is actually executed as the pre-processing. Further, it is determined whether or not the search result obtained as a result of performing the search processing is appropriate. For example, when five or more search results have been obtained, it is determined that a search result useful for the user can be presented. In this case, the adjusted search conditions are presented to the user by reflecting the adjusted search conditions in the trend setting area 11 of the search condition setting area 10.

  On the other hand, when it is difficult to present a search result useful to the user, such as when the number of search results is less than five, each evaluation value is adjusted again. For example, a search condition adjustment process for adjusting the search condition to the state shown in FIG. 9A is performed. Further, similarly to the above-described processing, it is determined whether or not the readjusted search condition is useful for the user, and whether or not the readjusted search condition is applied is determined.

Thus, it is ensured that the adjusted search condition presented to the user is a search condition that can obtain a certain degree of search result. That is, it is possible to increase the possibility that a search condition appropriate for the user is presented to the user, and to further increase the possibility that the user can obtain a desired search result when the user performs a search operation. it can.

[6-5. Modification 5]
One or more evaluation axes set in the recipe may be different for each recipe. For example, a certain recipe may have an evaluation axis whose label information is “full”, but another recipe may not have the evaluation axis.
When the search process is performed when the evaluation axes provided for each recipe are different, a recipe in which at least one evaluation axis matches the evaluation axis specified by the search condition is set as a search target. Further, a recipe along the tendency of each evaluation value under the specified search condition is extracted as a search result on the matching evaluation axis.
In addition, since the search conditions manually set by the user, that is, the target evaluation axis, are important elements for specifying the recipe desired by the user, at least recipes without the target evaluation axis are excluded from the search target. You may.

[6-6. Others]
In each of the above-described examples, an example of searching for a recipe of a dish has been described, but other search targets may be used. For example, a search condition setting area 10 as shown in FIG. 4 may be presented to the user for setting search conditions for searching various web page data.
In addition, the various modes exemplified above may be used as a system for searching for a used car that meets a user's request.
The search condition setting area as shown in FIG. 4 is most suitable when the user does not want to search for a specific thing, but wants to perform a search in which only a rough direction is determined. In this case, by setting an evaluation axis and an evaluation value for evaluating the tendency of each search object, it is possible to set various search conditions and execute the search processing described above.

  As an example of performing a search by determining only a rough direction, the present invention can also be applied to a case of searching for a picture or music, a matching system for a marriage partner, and the like. For example, in matching a marriage partner, it is difficult to find a perfect user having all the factors, and an evaluation axis having a low priority (such as “height”) is automatically determined according to the priority of the user. By performing the adjustment, it is possible to match an optimal partner for the user.

The various examples described above can be appropriately combined unless the combination is impossible.

<7. Summary>

As described in each of the above-described examples, an evaluation information management unit (recipe management unit 1a) that manages a plurality of evaluation axes and evaluation values assigned to each evaluation target (for example, a recipe), and specifies an evaluation axis and an evaluation value. The presentation control unit 1e that performs control for presenting a search condition setting unit (trend setting area 11) that can set a search condition of an evaluation target by performing the search operation, and a target evaluation axis that is a target of a change operation that changes the search condition. A change information acquisition unit 1b for acquiring information on the evaluation value before the change and the evaluation value after the change, and the sum of the evaluation values of all the evaluation axes according to the difference between the evaluation value before the change and the evaluation value after the change A search condition adjustment unit 1c that adjusts a search condition by changing an evaluation value of an adjustment evaluation axis that is at least one of the evaluation axes other than the target evaluation axis so that the value does not change by a predetermined value or more; Search based on criteria Includes a search processing unit 1d to extract the evaluation performed sense, the.
Adjustment to change the evaluation value of the adjustment evaluation axis is performed to suppress the change amount of the total value of the evaluation values of all the evaluation axes, so that the characteristic of the set value (evaluation value) set by the user on the target evaluation axis is easily displayed. Search conditions are set.
For example, when the evaluation value of the evaluation axis 13A is increased from 50 to 60, the difference from the evaluation value of another evaluation axis (for example, 50 which is an initial value) becomes 10 if the evaluation value is not changed, and the search condition in which the feature is hard to appear is obtained. Becomes However, as a process for adjusting the search condition, by performing a process of reducing the evaluation value of the other evaluation axis from 50 to 40 instead of increasing the evaluation value of the evaluation axis 13A, the difference from the other evaluation axis is reduced by 20. Thus, a search condition with more emphasized features can be automatically set.
In particular, by adjusting the change amount of the total value of the evaluation values to be small, for example, a search condition that maximizes the evaluation values of all the evaluation axes, in other words, there is a corresponding evaluation target as a search result. It is not possible to specify search conditions that would otherwise or significantly reduce. As a result, an appropriate search condition that enables presentation of some search results is set, and it is possible to avoid an undesirable situation in which search results cannot be obtained. In such a case, in order to obtain search results appropriately, the user may manually perform a setting to lower the evaluation value of another evaluation axis instead of increasing the evaluation value of some evaluation axis. Can be However, according to this configuration, such setting is automatically performed, thereby improving convenience.
In addition, the trend setting area 11 presented to the user in the various examples described above allows the search condition to be changed by a simple operation, and reduces the operation burden on the user when setting the search condition. Is possible.

As described in the example of the initial evaluation value determination process, the presentation control unit 1e specifies the initial value of the evaluation value and presents the search condition setting unit, and the initial value is the action history of the user who searches for the evaluation target. May be a numerical value based on
For example, if three levels of “cheap (evaluation value = 3)”, “normal (evaluation value = 2)”, and “high (evaluation value = 1)” can be specified for the evaluation axis of “price”, the user When searching for a search target, the presentation control unit specifies “3” as the initial value (default value) of the evaluation axis of “price” in response to specifying the evaluation value = 3 indicating that it is cheaper every time. The search condition setting means is presented in a state where is set.
Therefore, since the search condition setting means is presented in a state where the search condition according to the user's usual action is specified in advance, the user does not need to reset the evaluation value of each evaluation axis so as to change the usual search condition. It can be specified. That is, it is possible to reduce the complexity of the input operation (operation for setting the evaluation value).

As described in the example of the search condition adjustment processing, the search condition adjustment unit 1c may perform the adjustment so that the magnitude relation of the evaluation values between the adjustment evaluation axes does not collapse.
When the user specifies a condition for searching for an evaluation target, that is, when specifying an evaluation value, it is conceivable to specify a plurality of items. In this case, according to this configuration, the evaluation value of the evaluation axis is adjusted so that the magnitude relationship set for the evaluation axes other than the target evaluation axis set as the user's operation target does not collapse.
Thus, when the user specifies the evaluation values of a plurality of evaluation axes in order to set the condition that he / she wants to search, the user sets the next evaluation axis while inheriting the characteristics of the search conditions that have been set so far. This provides an environment for setting evaluation conditions that is easy to use.

As described in the example of the search condition adjustment processing, the search condition adjustment unit 1c may perform the adjustment so as not to change the ratio of the evaluation value between the adjustment evaluation axes.
When the search condition is set by the user performing an operation to specify the evaluation values of multiple evaluation axes, the setting must be made before changing the evaluation value of the target evaluation axis that is the next operation target The relationship between the already evaluated evaluation axes is maintained.
Thus, the user can set the evaluation value of the next evaluation axis while maintaining a predetermined ratio so that the relationship between the evaluation axes set up to that point is not lost. In other words, it is possible to provide a search condition setting unit that can easily provide the characteristics of the search condition.

As described in the second and third examples of the search condition adjusting process, the search condition adjusting unit 1c may determine the adjustment evaluation axis based on the relationship between each adjustment evaluation axis and the target evaluation axis. .
A positive correlation or a negative correlation may be found between the evaluation values of a plurality of evaluation axes. For example, when the user performs a change operation using the evaluation axis 13A as the target evaluation axis in the evaluation axes 13A and 13B where a negative correlation is seen, the evaluation axis 13B is selected as the adjustment evaluation axis, and the evaluation axis 13A is selected. It is conceivable to increase or decrease the evaluation value of the evaluation axis 13B in a direction opposite to the performed operation of increasing or decreasing the evaluation value.
Further, in the evaluation axes 13C and 13D where a positive correlation is seen, when the user performs a change operation with the evaluation axis 13C as the target evaluation axis, the evaluation axis 13D is selected as the adjustment evaluation axis and the evaluation value of the evaluation axis 13C is selected. The adjustment is performed in the same direction as the increase / decrease operation performed on the evaluation axis, and the evaluation value is adjusted in a direction different from the evaluation value increase / decrease operation performed on the evaluation axis 13C as the adjustment evaluation axis for the other evaluation axes. I do.
As a result, evaluation axes other than the target evaluation axis are not uniformly determined and adjusted as adjustment evaluation axes, but are adjusted appropriately based on the relationship between evaluation axes. This can be performed with a simple operation.
Note that the evaluation axis having a positive correlation is, for example, an evaluation axis of “luxury” and “price” or an evaluation axis of “deliciousness” and “low price” when the evaluation target is a recipe. . The evaluation axes having a negative correlation include, for example, the evaluation axes of “easiness” and “luxury” and the evaluation axes of “snacking feeling” and “fullness”. Of course, depending on the recipe, such a correlation is not always applied. However, when the correlation between the evaluation axes is viewed as a whole when viewed as a whole recipe, it is referred to as “an evaluation axis having a correlation”. I have.

As described in the fourth example of the search condition adjusting process, the change information acquiring unit 1b specifies a plurality of change operations received from the presentation of the search condition setting unit to the search process as a series of change operations, and performs the search. When performing adjustment according to the latest change operation in the series of change operations, the condition adjustment unit 1c removes at least a part of the evaluation axes set as the target evaluation axes in each of the series of change operations from the adjustment evaluation axis. May be adjusted.
For example, evaluation axes 13A to 13E that can be set by the user as search conditions are prepared, the user performs a change operation using the evaluation axis 13A as a target evaluation axis, and then performs a change operation using the evaluation axis 13B as a target evaluation axis. Is performed, instead of changing the evaluation value of the evaluation axis 13B according to the operation, another evaluation axis is used as an adjustment evaluation axis so that the total value does not change more than a predetermined value. At this time, according to this configuration, the evaluation axis 13A is removed from the adjustment evaluation axis in order to maintain the evaluation value specified by the user in the change operation.
Thus, it is possible to prevent the once set evaluation axis from being changed when another evaluation axis is changed, and to provide a user-friendly search condition setting unit.

As described in the example of the search condition adjustment processing and the like, the adjustment evaluation axis may be all evaluation axes other than the target evaluation axis.
Regardless of whether or not the user has previously performed a change operation, all evaluation axes other than the target evaluation axis are to be adjusted as adjustment evaluation axes. For example, when the user accidentally changes the evaluation value of the evaluation axis 13A and then changes the evaluation value of the evaluation axis 13B that the user originally wanted to change, the evaluation axis 13A is also set as the adjustment evaluation axis. Accordingly, it is possible to set search conditions according to the user's intention.
This makes it possible to set search conditions according to the user's intention.
In addition, after the user performs an operation of changing the evaluation value of the evaluation axis, by performing a specific operation such as pressing a reset button, all the evaluation axes other than the target evaluation axis are set as the adjusted evaluation axes. You may comprise.

As described in the example of the search query setting process, the search processing unit 1d determines that the evaluation value is equal to or more than the predetermined value when there is an evaluation axis whose evaluation value is equal to or more than the predetermined value in the adjusted search condition. The evaluation axis may be determined as the search condition evaluation axis, and the search processing may be performed based on the label information assigned to the search condition evaluation axis.
For example, when the evaluation value that can be taken in each evaluation axis is 0 to 100, the predetermined value is 80, and the evaluation value of the evaluation axis 13A exceeds 80 after adjustment, the evaluation axis 13A is used as the search condition evaluation axis. It is determined. Further, when the label of the evaluation axis 13A is set to "saving", a search process is performed so that a recipe having a high evaluation value of "saving" is extracted as a search result.
As a result, the user performs a search process reflecting the characteristics of the search condition set by a simple operation of changing each evaluation value, and can obtain a corresponding search result. That is, a desired recipe can be searched without performing a character input operation for inputting a search character string or the like, and convenience can be improved.

As described in the example of the search query setting process, when there are a plurality of search condition evaluation axes, the search processing unit 1d performs an AND search based on the label information assigned to each of the plurality of search condition evaluation axes. May be performed.
For example, if the evaluation values that can be taken on each evaluation axis are 0 to 100, the predetermined value is 80, and the evaluation values of the evaluation axes 13A and 13B exceed 80 after adjustment, the evaluation axes 13A and 13B Is determined as the search condition evaluation axis. Further, when the label of the evaluation axis 13A is set to "conserving" and the label of the evaluation axis 13B is set to "healthy", a recipe having a high evaluation value for "saving" and "healthy" is extracted as a search result. Search processing using the label information of the evaluation axis is performed.
This makes it possible to execute a simple search process on a seemingly complicated search condition in which respective evaluation values specified by the user are set for a plurality of evaluation axes, thereby obtaining a recipe desired by the user. , So that the processing load can be reduced.
Further, when a search operation using label information assigned to a plurality of evaluation axes is desired to be performed, it is only necessary to perform a simple operation of setting the evaluation value of the corresponding search axis to a predetermined value or more. Reduction can be achieved.
