[Outline of Information Processing System 1]
An overview of the information processing system 1 according to the first embodiment of the present invention will be described. The information processing system 1 according to the present embodiment provides a web service that allows information posted by a user to be disclosed to other users so that the information can be shared among the users. Below, the case of the web service which makes a recipe shareable is demonstrated as an example.

A web service provided by the information processing system 1 will be described.
FIG. 1 and FIG. 2 are diagrams showing display screens of web service applications according to the present embodiment. The information processing system 1 provides two posting (recording) functions including a recipe posting function and a report posting function. Information posted by these two posting functions is released on the website and can be referred to by other users.

The recipe posting function is a function for posting a recipe newly created by the user. With this function, it is possible to post cooking titles, ingredients and their quantities, cooking methods, cooking results cooking images, and the like. Hereinafter, an image posted by the recipe posting function is referred to as a recipe image.
The report posting function is a function for posting a report. Here, the report indicates an impression of the recipe posted by the recipe posting function. With this function, it is possible to post the contents described in the cooking method, the comment on the dish itself, the cooking image of the cooking result, and the like. Hereinafter, an image posted by the report posting function is referred to as a report image. That is, the image has at least two uses, that is, for recipe submission and for report submission.

  The display screen G1-1 in FIG. 1 is a screen that is a basic operation when posting a dish cooked by the user. The display screen G1-2 is a screen that is displayed when the selection button G1-3 marked “Cooking dishes” is selected on the display screen G1-1. When the selection button G1-3 is selected, the information processing system 1 extracts candidate images to be posted on the website from the cooking images captured by the user, and uses each extracted image for its use. Is estimated.

  The display screen G2-1 in FIG. 2 is a screen displayed when the dish image P1 is selected on the display screen G1-2 in FIG. In this example, the dish image P1 is presumed to be for report posting. Therefore, the information processing system 1 shows an input image for creating a report as the display screen G2-1. In the example of FIG. 2, the display screen G <b> 2-1 includes a cooking image P <b> 1, a candidate display G <b> 2-12 for a recipe that triggers cooking (hereinafter referred to as a target recipe), and a selection button for creating a report. G2-11 is displayed. Note that the user can select a recipe different from the displayed target recipe candidate by selecting the selection button G2-13. Further, the user can select a use different from that for the report estimated by the information processing system 1 for the dish image P1 by selecting the selection button G2-14.

On the display screen G2-2, the user can post a report by inputting food impressions and the like in the report description field G2-22 and selecting the selection button G2-21. As a result, the report is published on the website.

  The display screen G2-3 is a screen displayed when the dish image P2 is selected on the display screen G1-2. Since the cooking image P2 is estimated to be used for posting a recipe, an input image for posting a recipe is displayed as the display screen G2-3. The display screen G2-3 displays a cooking image P2, an input scene G2-32 for inputting a recipe title, and a selection button G2-31 for posting a recipe. Note that the user can select a use different from the use estimated by the information processing system 1 for the dish image P2 by selecting the selection button G2-33.

  The display screen G2-4 is a screen displayed when the selection button G2-31 on the display screen G2-3 is selected. The display screen G2-4 is provided with a selection button G2-41 for posting a recipe. In the display screen G2-4, the user inputs items necessary for posting a recipe, such as adding how to make it as needed, and inputting a catch phrase and the history of the recipe, and selects the selection button G2-41. By selecting, a recipe can be posted. Thereby, the recipe is published on the website.

  The display screen G2-5 is an example of a screen that displays a record of dishes cooked by the user. The date and time of cooking and the cooked recipe are displayed side by side on the display screen G2-5. The recipes displayed here include recipes submitted with recipes and recipes submitted with reports. For example, when the dish image P1 is posted as a report by the operation of the selection button G2-21, the recipe for the dish shown in the dish image P1 is displayed. For example, when the recipe image is posted on the dish image P2 by operating the selection button G2-41, the recipe for the dish shown in the dish image P2 is displayed. On the display screen G2-5, a recipe post or a report post may not be displayed, but a dish that is estimated to be cooked may also be displayed as a recording candidate.

Next, estimation of the use of an image will be described.
The information processing system 1 performs estimation using, for example, machine learning. For example, the information processing system 1 has a browsing history of recipes by an unspecified number of users, a questionnaire result that asks whether each of the unspecified number of users has performed a cooking action based on a recipe on a website, etc. Get information about. Then, the information processing system 1 performs machine learning using the browsing history and the questionnaire result as teaching data, and generates information (probability model) indicating the relationship between the browsing history and the cooking behavior as the learning result.

  And the information processing system 1 estimates whether the said target user performed cooking action based on the recipe on a website by inputting the browsing history of a target user into the produced | generated probability model. Here, when the information processing system 1 estimates that the cooking action based on the recipe on the website is performed in the time zone when the dish image is captured, the information processing system 1 estimates the dish image for report posting. Moreover, when it is estimated that the cooking action based on the recipe on a website is not performed in the time slot | zone when the cooking image was imaged, the said cooking image is estimated as a recipe contribution.

  In this way, the information processing system 1 determines whether the target user has performed an action based on the posted information based on the learning result learned by machine learning and the action history of the target user on the website where the posted information is posted. Is estimated. Further, the information processing system 1 can estimate the use of the image based on the action history on the network. Thereby, since the user does not need to determine the use of the image by himself / herself, it becomes easy to post a recipe or report. Therefore, the information processing system 1 can activate posting to the website and enhance the web service provided by the information processing system 1.

  The menu posting unit 182 performs a process for posting a menu. “Posting” means that other users can refer to the data edited by the user. In other words, “posting” is to publish data. However, “posted” data may be set not to be disclosed. “Editing” includes creating new data, modifying or adding information of existing data, deleting existing data, and the like.

  For example, when newly creating menu data or menu attribute data, the menu posting unit 182 newly assigns a menu ID. Then, menu data and menu attribute data are newly created by associating various types of information input by the user with the numbered menu ID. The menu posting unit 182 transmits the created menu data and menu attribute data to the recipe management device 30 for storage.

For example, when correcting or adding information on existing menu data or menu attribute data, the menu posting unit 182 stores the menu data and menu attribute data related to the menu specified by the user in the recipe management device 30. Get from. And the menu contribution part 182 processes the acquired menu data and menu attribute data according to the instruction | indication by a user.

  The search operation unit 185 performs processing for searching menus and recipes. Specifically, the search operation unit 185 notifies the recipe management device 30 of the search conditions input by the user and requests a search. In addition to the input keyword, the search condition may include specification of a search target range. For example, the menu, recipe type, popularity, registration date, and contributor may be specified as search conditions, in addition to whether menu is a search target or recipe is a search target. The search operation unit 185 acquires a search result from the recipe management device 30. The search result may include, for example, menu data, menu attribute data, recipe data, recipe attribute data, and the like.

  The estimation assisting unit 186 performs processing on the terminal device 10 side for estimating the use of the captured image. Specifically, when the user inputs an operation for starting cooking recording, the estimation assisting unit 186 displays image information for estimation of an image related to cooking among images stored in the image data storage unit 171. The management device 30 is notified, and the usage estimation is requested.

The image to be used for the purpose of use estimation may be extracted by recognizing whether or not an image of foodstuffs, cooking utensils, or the like is included in the image using a known image recognition technique, for example.
Moreover, the estimation auxiliary | assistant part 186 starts the process which estimates the use of the imaged image not only when a user performs operation input which starts the recording of cooking, but other arbitrary timings, for example, an image When the image is captured, the process may be started. In this case, when it is determined that the captured image is an image related to cooking, the estimation assisting unit 186 notifies the recipe management apparatus 30 of the image information for estimation of the image, and requests the estimation of usage.

The output processing unit 187 controls screen display and audio output. For example, the output processing unit 187 displays a screen for providing various functions of an information search service such as user authentication, menu, recipe, report editing, posting, and search on the display unit 16 or provides various functions. The audio is reproduced by the audio reproduction unit 15.

  The report editing unit 333 edits report data. The report editing unit 333 performs the same process on the report data as the menu editing unit 331 performs on the menu data and the menu attribute data.

  The search keyword acquisition unit 334 acquires a search keyword. Specifically, first, the extraction unit 335 acquires an input keyword and a search condition from the terminal device 10. Next, the search keyword acquisition unit 334 refers to the input keyword and corrects fluctuations and errors. Hereinafter, the corrected character string is referred to as a “first search keyword”. Next, the search keyword acquisition unit 334 refers to the ingredient data and the dish data, and acquires the ingredient, the ingredient belonging to the dish, the same kind ingredient, the belonging dish, and the same kind dish indicated by the first search keyword. That is, the name of the belonging food, the same kind of food, the belonging food, and the same kind of food is acquired as a search keyword. Hereinafter, a search keyword that is secondary specified from the first search keyword, such as the name of the belonging food, the same kind of food, the belonging food, and the same kind of food, is referred to as a “second search keyword”. Thus, the first search keyword and the second search keyword are specified as the search keyword. Hereinafter, the search result based on the first search keyword is referred to as “first search result”, and the search result based on the second search keyword is referred to as “second search result”. If these are not distinguished, they are simply referred to as “search results”.

  The extraction unit 335 searches for menus and recipes. Specifically, first, the extraction unit 335 refers to the menu attribute data and the recipe attribute data, and for example, the menu attribute data and the recipe attribute data include the first search keyword or the second search keyword in the menu name information and the recipe name information. To extract. Further, the extraction unit 335 extracts menu data and recipe data associated with the extracted menu attribute data and recipe attribute data by the menu ID and recipe ID.

In addition to the input keyword, the extraction unit 335 extracts only data satisfying the search condition when a search condition is separately specified. In addition, the extraction unit 335 extracts only permitted data according to the member setting.

  The history management unit 336 manages action history data. Specifically, when the history management unit 336 acquires an input keyword from the terminal device 10, the history management unit 336 newly assigns an action history ID. Then, the action history data is generated by associating the numbered action history ID with the first search keyword, the user ID, the platform ID, and the like, and stored in the action history data storage unit 328. Thereafter, when a selection is made on the search result, selection result information and selection date information are described in the action history data. Moreover, end date information is described at the end of browsing.

  The learning unit 337 refers to the behavior history data and the performance information, and uses the teaching data as data indicating the correspondence between the behavior histories of many users on the website and the actual behavior (actual performance) of each user. Perform machine learning. Specifically, for each of the behaviors indicated by the behavior history, data indicating the value of the behavior estimation parameter calculated from the behavior history and the value corresponding to the actual result are used as teaching data. Thereby, the machine history learns the relationship between the action history related to the browsing of the recipe and whether or not to perform the cooking action based on the recipe. For machine learning, for example, an arbitrary algorithm such as a neural network (deep learning) or a support vector machine may be used. Hereinafter, as an example, a case where a probability model is generated by machine learning will be described. In this case, the learning unit 337 generates a probability model by machine learning. The learning unit 337 outputs the behavior estimation data indicating the probability model to the behavior estimation data storage unit 329.

  Note that the learning unit 337 may use any information that can be calculated based on the behavior history as the behavior estimation parameter. For example, the learning unit 337 includes a time difference between a recipe browsing start time and an image capturing time, a platform used for browsing the recipe, whether the recipe is registered as a favorite, a time zone when the recipe is browsed, The length of the recipe browsing time, the recipe browsing order in browsing one session, the number of reports submitted to the recipe, and the like may be used as the action parameters.

  The estimation unit 338 executes image usage estimation processing. In the image usage estimation process, the estimation unit 338 estimates the user's behavior based on the result of machine learning by the learning unit 337, and estimates the usage of the image. Specifically, when the estimation unit 338 receives the estimation image information from the terminal device 10 and receives an estimation request for image usage, the estimation unit 338 refers to the estimation image information. Then, user action history data indicated by the imaging user information is extracted from the action history data storage unit 328. Furthermore, the estimation unit 338 extracts behavior history data indicating the behavior history of a predetermined period before the image capturing time, and sets it as an analysis target. The extracted behavior history data indicates the behavior history before the image is captured, and is useful for estimating the user's behavior immediately before the image is captured. Here, in order to simplify the description, a case will be described in which the behavior history immediately before the image capturing time is selected as the analysis target among the behavior histories before the image capturing time. However, there may be a plurality of behavior histories to be analyzed. The behavior history to be analyzed may include not only the behavior history before the image capturing time but also the behavior history after. In this case, the estimation result associated with the image may be narrowed down by adopting the estimation result with the highest likelihood among the estimation results based on each action history.

  The estimation unit 338 calculates a behavior estimation parameter based on the behavior history to be analyzed and the estimation image information. The estimation unit 338 acquires the estimation result by inputting the calculated behavior estimation parameter to the probability model indicated by the behavior estimation data. Then, the estimation unit 338 transmits estimation result information indicating the estimation result to the terminal device 10. The estimation result information includes image ID, user ID, information indicating whether cooking has been performed with reference to a recipe (that is, whether the report is for posting, or for recipe posting). In addition, since the estimation result is obtained for each action history, when it is estimated that the report is for posting, it is determined which recipe is referred to. Accordingly, the estimation result can include the recipe ID of the referenced recipe.

  As described above, as the behavior estimation parameter, the time difference between the recipe browsing start time and the image capturing time, the platform used for browsing the recipe, the time zone when the recipe was browsed, and whether it is registered as a favorite No, the length of the recipe browsing time, the browsing order of recipes in one session browsing, the number of reports submitted to the recipe, and the like can be used.

  For example, the elapsed time from the recipe browsing start time has a correlation with whether or not a cooking action based on the recipe is performed. Specifically, if the time has not elapsed since browsing the recipe, the possibility of cooking based on the recipe is high. On the other hand, if a long time has elapsed since browsing the recipe, it is assumed that the possibility of cooking based on the recipe decreases. Therefore, by including the elapsed time from the recipe browsing start time, that is, the time difference between the recipe browsing start time and the image capturing time, in the behavior estimation parameter, more accurate estimation can be performed.

  For example, the platform on which the recipe is used for browsing correlates with whether or not the cooking action based on the recipe is performed. Specifically, the user layer differs depending on the model of the terminal device 10 to be used and the type of OS. In other words, the platform can determine to some extent whether or not the user is actively cooking. Further, in the case of a desktop personal computer, the installation location is limited, so that it is difficult to place the recipe in a kitchen or other place where it is easy to view the recipe. Therefore, more accurate estimation can be performed by including the platform used for browsing the recipe in the behavior estimation parameter.

  Further, for example, the time period when the recipe is browsed is correlated with whether or not the cooking action based on the recipe is performed. Specifically, it is conceivable that recipes that are referenced in a predetermined time zone before dinner such as from 16:00 to 17:00 tend to be cooked as dinner of the day. Therefore, more accurate estimation can be performed by including the time zone in which the recipe is browsed in the behavior estimation parameter.

  For example, whether or not a recipe is registered as a favorite has a correlation with whether or not a cooking action based on the recipe is performed. Specifically, it is conceivable that recipes registered as favorites tend to have many recipes registered by the user for cooking. That is, there is a high possibility that a favorite registered recipe is actually cooked. Therefore, more accurate estimation can be performed by including in the behavior estimation parameter whether the recipe is registered as a favorite.

Further, for example, the number of report posts is correlated with whether or not cooking behavior based on a recipe is performed. For example, recipes with a large number of report submissions have a track record of cooking by many users for reasons such as being easy to make and delicious, and are likely to be cooked in the future.
Therefore, more accurate estimation can be performed by including the number of recipe posts in the behavior estimation parameter.

  Further, for example, the order of browsing the recipe in browsing one session correlates with whether or not the cooking action based on the recipe is performed. Specifically, when a user searches for a recipe for a dinner menu tonight, the recipe search tends to end when the dinner menu is determined. That is, in browsing one session, it is assumed that the recipe browsed in the second half is more likely to be actually cooked than the recipe browsed in the first half. Therefore, more accurate estimation can be performed by including the recipe browsing order in the browsing of one session in the action estimation parameter.

Further, for example, the length of the recipe browsing time is correlated with whether or not the cooking action based on the recipe is performed. Specifically, it is conceivable that the recipe that the user actually wants to cook tends to be referred to for a longer time compared to a recipe that is merely viewed. That is, if the recipe browsing time is long, the possibility of cooking is high, and if the recipe browsing time is short, the possibility of cooking is low. Therefore, more accurate estimation can be performed by including the length of the recipe browsing time in the behavior estimation parameter.
The above is the description of the configuration of the recipe management device 30.

[Configuration of User Management Device 50]
Next, the configuration of the user management device 50 will be described.

Further, the user management side control unit 53 may be realized as an integrated circuit such as an ASIC. The user management side control unit 53 includes a user management unit 531.

The user management unit 531 manages user data. The user management unit 531 generates user data and stores the user data in the user data storage unit 521, reads the user data from the user data storage unit 521, and provides the user data to the terminal device 10 or the recipe management device 30. Further, when the user management device 50 obtains a user authentication request from the terminal device 10, the user management device 50 collates the user ID and password of the user data stored in the user data storage unit 521 with the user ID and password included in the authentication request. And authenticate the user. The user management unit 531 provides user data to the terminal device 10 of the authenticated user.

FIG. 18 is a sequence chart showing the flow of image use estimation processing by the information processing system 1.

(Step S <b> 10) The terminal device 10 extracts an image related to cooking from the stock of the captured images. Thereafter, the information processing system 1 advances the processing to step S11.
(Step S11) The terminal apparatus 10 acquires image information for estimation including an image ID, imaging user information, and imaging time information for the extracted image. Thereafter, the information processing system 1 advances the processing to step S12.
(Step S12) The terminal device 10 acquires image information for estimation. Thereafter, the information processing system 1 advances the processing to step S13.
(Step S <b> 13) The recipe management device 30 extracts action history data to be analyzed based on the estimation image information received from the terminal device 10. Thereafter, the information processing system 1 advances the processing to step S14.
(Step S14) The recipe management device 30 refers to the behavior history data to be analyzed and calculates a behavior estimation parameter. Then, the user's behavior is estimated based on the calculated estimation parameter and the probability model. That is, the use of the image is estimated. Thereafter, the information processing system 1 advances the processing to step S15.
(Step S <b> 15) The recipe management device 30 transmits estimation result information to the terminal device 10. Thereafter, the information processing system 1 advances the processing to step S16.
(Step S16) The recipe management device 30 describes the estimation result indicated by the estimation result information in the estimated use information of the image data. For example, thereafter, the information processing system 1 ends the process described in this flowchart.
The above is the description of the operation of the information processing system 1 in the image usage estimation process.

  Here, a specific example of the process of step S13 will be described. Here, as an example, a case will be described in which a time difference between a recipe browsing start time and an image capturing time is used as a behavior estimation parameter.

FIG. 19 is a diagram illustrating a learning result indicated by the behavior estimation data.
In the example shown in FIG. 19, time difference information, recipe posting use estimation probability information, and report posting use estimation probability information are associated with each other as a learning result.
The time difference information is information indicating a difference between the recipe browsing start time and the imaging time when the dish image is captured.
The recipe posting use estimation probability information is information indicating the probability that the use of the dish image is for recipe posting. In other words, the recipe posting use estimation probability information is information indicating the probability of being newly cooked without being based on a recipe.
The report posting use estimation probability information is information indicating the probability that the use of the dish image is for report posting. In other words, the report posting use estimated probability information is information indicating the probability of cooking based on the recipe.
By referring to such a learning result, the terminal device 10 and the recipe management device 30 can determine the target based on the time difference between the time when the target user starts browsing the recipe and the time when the dish image is captured. User behavior can be estimated. Therefore, the use of the dish image can be specified.

FIG. 20 is a flowchart showing the process flow of step S13.
(Step S20) The recipe management device 30 specifies the image capturing time TA from the image information for estimation. Thereafter, the information processing system 1 advances the processing to step S21.
(Step S21) The recipe management device 30 extracts a recipe browsing start time TB based on the behavior history data to be analyzed. Thereafter, the information processing system 1 advances the processing to step S22.
(Step S22) The recipe management device 30 calculates the difference (TA−TB) between the imaging time TA and the browsing start time TB. Next, the recipe management apparatus 30 inputs a difference (TA-TB) to the probability model that is the learning result. The recipe management device 30 acquires an estimated probability for each action. For example, by using the difference (TA-TB) as input as the time difference information shown in FIG. 19, recipe posting use estimation probability information and report posting use estimation probability information can be acquired. Then, the information processing system 1 identifies an action with the highest estimated probability. For example, if the probability estimated for report submission is the highest (step S23; YES), the process proceeds to step S23. For example, when the probability estimated for recipe submission is the highest (step S23; NO), the process proceeds to step S24.
(Step S23) The recipe management device 30 estimates the use of the image as a report posting. Thereafter, the information processing system 1 ends the processing described in this flowchart.
(Step S <b> 24) The recipe management device 30 estimates that the use of the image is for recipe submission. Thereafter, the information processing system 1 ends the processing described in this flowchart.
The above is the description of the operation of the information processing system 1.

Further, for example, each configuration described in the above-described embodiment can be provided in a separate device. For example, the configuration of the recipe management device 30 may be provided in the terminal device 10, or a part or all of the configuration of the terminal device 10 may be provided in the recipe management device 30.

In the above-described embodiment, the web service that publishes the recipe and its report has been described. However, the present invention is not limited to this. The information processing system 1 can be applied to, for example, a web service that posts a travel plan and its report.
In addition, although embodiment mentioned above demonstrated the case where the information which can be calculated based on action history was used as a parameter for action estimation, it is not restricted to this. Arbitrary information may be used for the behavior estimation parameter. For example, information that can be calculated based on the user's attribute information or the type of the object captured in the image may be used. For example, a user's member setting, sex, age, whether or not a cooking utensil is shown, and the like may be used as behavior estimation parameters. For example, image continuity may be used as a behavior estimation parameter. For example, when an image is taken with the intention of posting a recipe, the image may be taken at each step of the cooking procedure. For this reason, for example, by using the interval between image capturing times as a behavior estimation parameter, it is possible to accurately estimate whether or not it is for recipe posting.

  In the above-described embodiment, the case has been described in which the behavior estimation result is used for image usage estimation, but the behavior estimation result may be used for other purposes. For example, an advertisement of a recipe related to a recipe estimated to be cooked or a recommended cooking utensil may be presented according to the estimation result of the behavior.

For example, it may be estimated that cooking is performed by arranging the viewed recipes. And when it is estimated that cooking has been performed by arranging, the recipe posting screen is displayed, and information on the recipe viewed at the time of arranging may be input to each item for posting. . This makes it easier to post recipes. Further, it may be estimated that neither the recipe submission nor the report submission is performed. For example, information indicating whether the image capturing location is the user's home or outside is used as the behavior estimation parameter. And when it is outside a house, you may determine with it not being the image which the user cooked. Note that the location of the user's house may be specified by referring to the user attribute information, or the location where the dish image is repeatedly captured may be specified as the location of the house.
