[0013] 1. Configuration of Information Providing System 100 The processing of an information provision system (referred to as "this system" where appropriate) 100 according to this embodiment will be described using Fig. 1. Fig. 1 is a diagram showing an example of the configuration of the information provision system 100 according to this embodiment. Below, the example of the configuration of this system 100, the processing of this system 100, the set matching technology applied in this system 100, and the effects of this system 100 will be described in that order.

[0014] (1-1. Configuration example of information provision system 100) 1 includes an information providing device 10, a user terminal 20, a website server 30, and a behavior information database 40. The information providing device 10, the user terminal 20, the website server 30, and the behavior information database 40 are communicably connected via a predetermined communication network (not shown) by wire or wirelessly. Note that the system 100 may include a plurality of information providing devices 10, a plurality of user terminals 20, a plurality of website servers 30, or a plurality of behavior information databases 40.

[0015] (1-1-1. Information provision device 10) The information providing device 10 is a device that transmits and receives data between the user terminal 20, the website server 30, and the behavior information database 40, and is realized by, for example, a server device or a cloud system. The example in Fig. 1 shows a case where the information providing device 10 is realized by a server device.

[0016] (1-1-2. User terminal 20) The user terminal 20 is a device (computer) used by a user U to browse web pages, conduct internet shopping on the web, etc. The user terminal 20 accepts operations by the user U. The user terminal 20 may be realized, for example, by a smartphone, a tablet terminal, a notebook PC (Personal Computer), a desktop PC, a mobile phone, a PDA (Personal Digital Assistant), etc. The example in FIG. 1 shows a case where the user terminal 20 is realized by a smartphone.

[0017] Hereinafter, the user terminal 20 may be referred to as the user U. That is, the user U may be read as the user terminal 20. The user U may also be used to represent multiple customers.

[0018] (1-1-3. Website Server 30) The website server 30 is a device that transmits and receives data to and from the information providing device 10 and the user terminal 20, and is realized, for example, by a server device or a cloud system. The example in FIG. 1 shows a case where the information providing device 10 is realized by a server device. The website server 30 is a device used by a service provider that provides services such as internet shopping to the user U on the web.

[0019] (1-1-4. Behavioral Information Database 40) The behavior information database 40 is a storage device that stores behavior information relating to hair behavior, which will be described later. The behavior information database 40 may store the behavior information as a part of the website server 30.

[0020] (1-2. Processing of Information Providing System 100) The following describes the processing of steps S1 to S7 as the processing of the information providing system 100. Note that the following steps S1 to S7 may be executed in a different order. Also, some of the processing of the following steps S1 to S7 may be omitted.

[0021] (1-2-1. Processing of step S1) In this system 100, first, a user U selects clothing items to purchase or consider purchasing via the user terminal 20, and transmits the selection of clothing items to the website server 30 (step S1). Here, clothing items refer to items such as clothes, footwear, and accessories provided to the user U by a business using the website server 30 of this system 100. For example, clothing items include clothing such as tops and bottoms, footwear such as shoes and socks, and accessories such as hats, glasses, gloves, rings, necklaces, earrings, and hair ornaments. Furthermore, clothing items may also be carrying items such as bags, backpacks, and waist pouches, and are not particularly limited.

[0022] (1-2-2. Processing of step S2) Secondly, in the present system 100, the information providing device 10 acquires product information about the clothing item selected by the user U from the website server 30 (step S2). Here, the product information is information about the clothing item, such as, but not limited to, a video image of the clothing item, the product name, the type and classification of the product, the price, the available sizes and colors, as well as the manufacturer name, the brand name, and related products. In the example of FIG. 1, the information providing device 10 acquires the product information from the website server 30, but it may also acquire the product information from the user terminal 20 or a terminal device or database (not shown).

[0023] At this time, the information providing device 10 may acquire user information of the user U from the user terminal 20. Here, the user information is information including user attributes such as the user U's gender, age, generation, occupation, annual income, place of residence, marital status, whether the user U has children, videos of the user U, categories of interest to the user U, and behavioral history such as the user U's search history and browsing history on websites, purchase history in internet shopping, and location information of the user U. Furthermore, the user information may be information including screen information of the user terminal 20, biometric information of the user U, and the like, and is not particularly limited.

[0024] (1-2-3. Processing of step S3) Third, in the present system 100, the information providing device 10 refers to the behavior information database 40 and acquires behavior information (step S3). Here, behavior information is information about hair behavior indicating the overall hairstyle, such as hairstyle and hair color. The behavior information may also be information about the hair behavior using a wig or toupee, and is not particularly limited. In the example of FIG. 1, the information providing device 10 acquires behavior information from the behavior information database 40, but it may also acquire behavior information from the website server 30 or a terminal device database (not shown).

[0025] (1-2-4. Processing of step S4) Fourth, in the present system 100, the information providing device 10 calculates a compatibility degree indicating the degree of compatibility between the clothing item selected by the user U and the hair style from the acquired product information and appearance information (step S4). For example, the information providing device 10 uses a machine learning model to calculate the compatibility degree so that it takes a numerical value between 0 and 1 depending on the degree of compatibility between the combination of the clothing item and the hair style. In this case, the information providing device 10 calculates the compatibility degree using a machine learning model such as a DNN (Deep Neural Network) that has been trained to output the compatibility degree for each combination of the clothing item and the hair style when the product information and appearance information related to the clothing item selected by the user U are input. Alternatively, the information providing device 10 may calculate the compatibility degree based on rules.

[0026] The above-mentioned step S4 will be described using a specific example. For example, the information providing device 10 can calculate the compatibility degree using a machine learning model trained for each user U, a machine learning model trained for each attribute of the user U, and a machine learning model trained for each situation of the user U, as shown below.

[0027] The information providing device 10 can calculate the degree of compatibility using a machine learning model trained for each user U. For example, the information providing device 10 causes the machine learning model to learn matching between clothes and hairstyles in images that the user U views on a social networking service (SNS) and has given high ratings such as "likes." As a result, the information providing device 10 can suggest a coordinating hairstyle and a salon when the user U selects clothes.

[0028] Furthermore, the information providing device 10 can calculate the compatibility degree using a machine learning model trained for each attribute, including the hobbies and preferences of the user U. For example, the information providing device 10 generates multiple machine learning models for a user who likes "XX (e.g., celebrity, era, type of drama (action, etc.))" and generates correct answer data for each machine learning model. Specifically, the information providing device 10 trains the machine learning model using images that have been "liked" by a subject who likes "XX" or images that match "XX" as correct answer data. As a result, when the user U accesses a website, the information providing device 10 can select a machine learning model that matches the user attributes of the user U and suggest a hairstyle that is deemed to have a high compatibility degree by the selected machine learning model.

[0029] Furthermore, the information providing device 10 can calculate the compatibility degree using a machine learning model trained for each situation of the user U. For example, for each corporate recruitment situation, such as new graduates, job changes, and mid-career recruitment, the information providing device 10 generates a machine learning model for each of new graduates, job changes, and mid-career recruitment, using images of candidates who passed the document screening during their job hunting activities as correct answer data. Therefore, for example, if the user U selects "job changes," the information providing device 10 can suggest a hairstyle that is appropriate for the document screening at the time of job change.

[0030] (1-2-5. Processing of step S5) Fifth, in the present system 100, the information providing device 10 generates information to be provided to the user U based on the calculated compatibility, the acquired appearance information, and the user information of the user U (step S5). Here, the provided information is information about the hair style identified from the hair style indicated by the appearance information, such as a hairstyle, hair color, etc. that matches the clothing item selected by the user U, and information about beauty salons, barber shops, etc. that can provide the hair style. At this time, the information providing device 10 identifies hair styles indicated by the appearance information that have a compatibility level equal to or greater than a predetermined threshold, and generates the provided information. For example, the information providing device 10 identifies an image of a hairstyle that has a compatibility level of "0.7" or higher with the top selected by the user U, and generates the provided information about the image and beauty salons that can provide the hairstyle indicated in the image.

[0031] The above-mentioned step S5 will be described using a specific example. For example, the information providing device 10 can generate information to be provided based on user information of a user U, or can generate information to be provided based on business information of a beauty salon or the like, as shown below.

[0032] The information providing device 10 can generate information to be provided based on user attributes indicated by the user information. For example, the information providing device 10 can identify the user U's hair color based on an image of the user U and suggest a group of hairstyles with relatively similar hair colors. The information providing device 10 can also preferentially suggest, among candidate hair styles, hairstyles similar to the preferred hairstyles registered in advance by the user U. Furthermore, even if the user U's hair style or preferences are unknown, the information providing device 10 can preferentially suggest images with hair colors relatively similar to the hair color of a product image selected by the user U on an internet shopping site. Therefore, the information providing device 10 can suggest highly similar hair styles from among the candidates identified from the style information based on the user attributes, etc.

[0033] Furthermore, the information providing device 10 can generate information to be provided based on the behavioral history indicated by the user information. For example, if the information providing device 10 can estimate the belongings of the user U based on the behavioral history such as the purchase history of the user U, it will suggest a hairstyle based on the belongings. Specifically, if the user U has a history of purchasing a "skirt," the information providing device 10 obtains from the website server 30 an image of the "T-shirt" selected by the user U and an image of a "skirt" previously purchased by the user U, and identifies hairstyles to be suggested by combining the "T-shirt" and the "skirt" with various hairstyles.

[0034] Furthermore, the information providing device 10 can generate provided information based on business information. For example, the information providing device 10 acquires information on beauty salons and the like as business information from the website server 30, and information on reservation sites for the beauty salons and the like, and generates suggested information including the acquired information. Therefore, the information providing device 10 can not only suggest a hairstyle that matches the clothes purchased by the user U, but also provide information on beauty salons and stylists who can achieve the hairstyle.

[0035] (1-2-6. Processing of step S6) In the present system 100, sixthly, the information providing device 10 transmits the generated information to the user terminal 20 of the user U (step S6). For example, the information providing device 10 transmits to the user terminal 20 of the user U information to be provided, including an image of a hairstyle whose compatibility with the top selected by the user U is 0.7 or higher and information on beauty salons that can provide the hairstyle shown in the image. At this time, the information providing device 10 can also provide the generated information to the user U by transmitting the information to the website server 30.

[0036] As in steps S1 to S6 described above, the information providing device 10 is a device that can analyze, for example, the hairstyle and hair color of a fashion model wearing an item of clothing selected by the user U, and provide hairstyle, stylist, and beauty salon information (information about beauty salons and barber shops). That is, when an item of clothing is selected in step S1 described above and the fashion model is wearing the selected item of clothing, the information providing device 10 can provide the user U with information about similar hairstyles, stylists who have posted the hairstyles, and the beauty salons to which the stylists belong, from the appearance information database 40. In this case, the information providing device 10 may provide reservation information, such as a reservation site for the beauty salon, as the beauty salon information. Furthermore, when the user U makes a reservation at the beauty salon and the treatment is actually performed, the information providing device 10 can also charge the beauty salon or stylist a customer referral fee.

[0037] (1-2-7. Processing of step S7) Seventh, in the present system 100, the information providing device 10 learns the calculated compatibility degree (step S7). For example, the information providing device 10 uses a machine learning model to learn using backpropagation or the like so that when information indicating a good compatibility between a clothing item selected by the user U and a hair style is input, the information providing device 10 outputs the compatibility degree of the hair style with the clothing item as a numerical value approaching "1." Furthermore, when information indicating a bad compatibility between a clothing item selected by the user U and a hair style is input, the information providing device 10 uses a machine learning model to learn using backpropagation or the like so that the information providing device 10 outputs the compatibility degree of the hair style with the clothing item as a numerical value approaching "0."

[0038] (1-3. Set matching technology applied in the information provision system 100) Here, the set matching technology applied in the information provision system 100 described above will be described in detail. A technology called set matching is known as an example of a technology for calculating a score indicating the degree of harmony between sets (hereinafter referred to as a "matching score" as appropriate) based on a set of information indicating feature quantities such as images. Set matching is a technology that uses, for example, deep learning, and estimates that the higher the matching score, the higher the compatibility between the sets. Therefore, set matching can quantitatively evaluate the compatibility between the sets. The calculation of a matching score using set matching is disclosed, for example, in "Exchangeable Deep Neural Networks for Set-to-Set Matching and Learning" by Y. Saito, T. Nakamura, H. Hachiya, and K. Fukumizu. Note that set matching is just an example, and embodiments are not limited to those using this technology.

[0039] The information providing device 10 calculates a matching score (compatibility) for each combination of clothing item and hair style by applying a technique for calculating matching scores between sets, such as set matching. Specifically, the information providing device 10 calculates the compatibility between the hair style and each clothing item selected by the user U. At this time, the information providing device 10 can estimate that the higher the compatibility, the higher the compatibility between the clothing item selected by the user U and the hair style. Therefore, the information providing device 10 identifies the hair style that has been calculated to have the highest compatibility for one clothing item. Furthermore, the information providing device 10 estimates that the identified hair style for one clothing item is the hair style with the highest compatibility among the hair styles included in the style information. This allows the information providing device 10 to quantitatively determine the compatibility between the clothing item and the hair style, rather than relying on the user U's subjective judgment of appearance, etc.

[0040] The information providing device 10 also trains the machine learning model as follows. For example, the information providing device 10 identifies images posted on an SNS that have been favorably rated by the user U. Next, the information providing device 10 identifies the hair style and clothing item in the identified image. At this time, the information providing device 10 may use various identification models or may obtain identification results through crowdsourcing, etc. The information providing device 10 uses the above identification result as correct answer data. Alternatively, the information providing device 10 may use the results of identification from images posted by the user U as correct answer data. The information providing device 10 then trains the machine learning model so that it outputs a high score when a hair style and clothing item that are correct answer data are input, and outputs a low score when a hair style and clothing item that are not included in the correct answer data are input. At this time, the information providing device 10 may generate such a machine learning model for each attribute of the user U or for each situation of the user. Furthermore, the information providing device 10 may reflect the degree of compatibility taking into account multiple perspectives by employing manipulation of the output values ​​of multiple models as the output of the machine learning model.

[0041] (1-4. Effects of the information provision system 100) As described above, in the information providing system 100, the information providing device 10 acquires product information regarding clothing items selected by the user U, calculates a compatibility score indicating the degree of compatibility between the clothing items selected by the user U and a hair style based on the product information, and generates information to be provided to the user U based on the compatibility score. The information providing device 10 calculates the compatibility score using a machine learning model that has learned the degree of compatibility between a hair style and clothing items worn by a subject with that hair style. Therefore, the system 100 can estimate a hairstyle that matches the clothing viewed by the user U or the clothing the user U wishes to purchase, and suggest hairstyles and stylists to the user U. Furthermore, the system 100 can estimate hairstyles that go well with accessories, shoes, bags, etc., in addition to the clothing selected by the user U, and suggest hairstyles and stylists to the user U. In other words, the system 100 can provide useful information to the user U on an EC (electronic commerce) site or the like.

[0042] Furthermore, in the present system 100, the information providing device 10 further acquires user information about the user U who selected the clothing item, identifies the hair style based on the acquired user information, and generates information to be provided. The information providing device 10 also generates information to be provided that includes business information about businesses that can provide hair styles. Therefore, the present system 100 can suggest to the user U hairstyles that go well with clothes that are highly rated on social media or clothes worn by celebrities, etc., and can also make more specific suggestions, such as suggestions about stylists who can achieve the hairstyles. In other words, the present system 100 can provide more specific and useful information to the user U of an e-commerce site, etc.

[0043] Furthermore, in the present system 100, the information providing device 10 calculates the compatibility level using a machine learning model that has learned the compatibility level between a hair style and a clothing item worn by a subject with that hair style. The information providing device 10 calculates the compatibility level using a machine learning model that has learned the compatibility level using video images including clothing items and hair styles, a machine learning model that has learned the compatibility level for each user U, a machine learning model that has learned the compatibility level for each attribute of user U, or a machine learning model that has learned the compatibility level for each situation of user U. Therefore, the present system 100 generates various machine learning models trained using corrective data collected from social media, television, movies, etc., and can suggest hairstyles to user U with higher accuracy. In other words, the present system 100 enables more specific and useful information to be provided to user U on e-commerce sites, etc., with high accuracy.

Note that the internal configuration of the control unit 13 is not limited to the configuration shown in Fig. 2, and may be other configurations as long as they perform the information processing described below. Furthermore, the connection relationship between the processing units included in the control unit 13 is not limited to the connection relationship shown in Fig. 2, and may be other connection relationships.

[0061] (2-3-1. Acquisition part 13a) The acquisition unit 13a acquires product information related to clothing and accessories selected by the user. For example, the acquisition unit 13a acquires, from the website server 30, information related to the products selected by the user U, such as clothes, footwear, and accessories.

[0062] The acquiring unit 13a also acquires appearance information related to hair appearance. For example, the acquiring unit 13a acquires, as appearance information, information on hair appearance indicating general hairstyles such as hairstyle and hair color from the appearance information database 40. At this time, the acquiring unit 13a may acquire, from the appearance information database 40, appearance information associated by a service provider in the website server 30. The acquiring unit 13a may also acquire, from the website server 30, appearance information including hair appearances that have been registered in advance as hair appearances that are highly compatible with each clothing item.

[0063] The acquisition unit 13a also acquires user information about the user U who selected the clothing item. For example, the acquisition unit 13a acquires user information from the user terminal 20 of the user U, such as user attributes including the user U's video images, categories of interest, etc., and the user U's behavioral history such as search history, browsing history, purchase history, location information, etc.

[0064] Furthermore, the acquisition unit 13a may acquire business information including information on registered beauty salons and stylists from the website server 30. The acquisition unit 13a can also acquire business information including information on beauty salons and stylists associated with hair styles from the style information database 40.

[0065] The acquiring unit 13a stores the acquired product information in the product information storage unit 12a. The acquiring unit 13a also stores the acquired behavior information and business information in the behavior information storage unit 12b. Furthermore, the acquiring unit 13a can also store the acquired user information in the storage unit 12.

[0066] (2-3-2. Calculation unit 13b) The calculation unit 13b calculates a compatibility degree indicating the degree of compatibility between a combination of a clothing item and a hair style based on the item information. For example, the calculation method will be described. The calculation unit 13b calculates the compatibility degree using a machine learning model that has learned the degree of compatibility between a combination of a hair style and a clothing item worn by a subject having the hair style. As a specific example, the calculation unit 13b calculates the compatibility degree using a machine learning model such as a DNN that has been trained to output the compatibility degree for each hair style with the clothing item when the item information and style information selected by the user U are input. Alternatively, the calculation unit 13b may calculate the compatibility degree for each hair style with the clothing item selected by the user U based on a rule.

[0067] Regarding the calculated numerical value, the calculation unit 13b calculates the compatibility degree so that it takes a numerical value between 0 and 1 according to the degree of compatibility for each hair style. The calculation unit 13b may also calculate the compatibility degree so that it takes a numerical value between 0 and 100% according to the degree of compatibility for each hair style, and the range and unit of the calculated numerical value are not particularly limited.

[0068] To explain this using a specific example, if the compatibility between item I and hairstyle H1 is "0.9," the compatibility between item I and hairstyle H2 is "0.8," and the compatibility between item I and hairstyle H3 is "0.7," the calculation unit 13b estimates that hairstyle H1, which has the highest compatibility, has a high compatibility with item I. This allows the calculation unit 13b to appropriately optimize the combination of clothing items and hair styles.

[0069] Furthermore, the learning data of the machine learning model used by the calculation unit 13b will be explained. The calculation unit 13b calculates the compatibility degree using a machine learning model that has learned the degree of compatibility from videos including clothing accessories and hairstyles. As a specific example, the calculation unit 13b calculates the compatibility degree using a machine learning model that has learned the degree of compatibility from videos, still images, etc. in which clothing accessories and hairstyles are simultaneously shown, collected from websites, SNS, television, movies, etc.

[0070] Furthermore, to explain the type of machine learning model used by the calculation unit 13b, the calculation unit 13b calculates the degree of compatibility using a machine learning model that has learned the degree of compatibility for each user U. As a specific example, the calculation unit 13b calculates the degree of compatibility using a machine learning model that has learned matching between clothes and hairstyles in images that the user U has viewed on an SNS and given high ratings such as "likes."

[0071] Furthermore, the calculation unit 13b calculates the compatibility degree using a machine learning model that has learned the degree of compatibility for each attribute of the user U. As a specific example, the calculation unit 13b calculates the compatibility degree using a plurality of machine learning models generated for each user attribute including the age of the user U and hobbies and preferences such as favorite entertainers and types of dramas.

[0072] Furthermore, the calculation unit 13b calculates the degree of compatibility using a machine learning model that has learned the degree of compatibility for each situation of the user U. As a specific example, the information providing device 10 calculates the degree of compatibility for each situation, such as new graduate, job change, mid-career recruitment, etc., using a machine learning model that has learned images of candidates who passed document screening during their job hunting activities.

[0073] The calculation unit 13b acquires item information related to the clothing item selected by the user U from the item information storage unit 12a. The calculation unit 13b also acquires hair style information indicating the hair style from the style information storage unit 12b. Meanwhile, the calculation unit 13b stores the calculated compatibility degree in the compatibility degree information storage unit 12c.

[0074] (2-3-3. Generation unit 13c) The generation unit 13c generates information to be provided to the user U based on the calculated compatibility. For example, the generation unit 13c identifies hair styles having a compatibility level equal to or higher than a predetermined threshold among the hair styles indicated by the acquired hair style information, and generates information to be provided. To explain using a specific example, the generation unit 13c identifies hairstyles H1, H2, H3, ..., which are hair styles for an item I that is a top clothing item, and identifies hairstyles H1, H2, and H3 having a compatibility level equal to or higher than "0.7" with the item I, and generates information to be provided that includes images of the hairstyles H1, H2, and H3.

[0075] Furthermore, the generation unit 13c identifies the hair style based on the acquired user information of the user U and generates information to be provided. For example, the generation unit 13c identifies a hair style registered as a preference of the user U from among hair styles having a compatibility degree equal to or greater than a predetermined threshold, and generates information to be provided that includes the hair style.

[0076] Furthermore, the generation unit 13c generates provided information including business information about businesses that can provide hair styles. For example, the generation unit 13c generates provided information that includes information about a beauty salon or stylist that provided an image of a hair style with a compatibility level equal to or higher than a predetermined threshold. In this case, the generation unit 13c may generate information that includes a link to the reservation page of the beauty salon or stylist as information about the beauty salon or stylist. In addition, when a user U makes a reservation at the beauty salon or stylist and the treatment is actually performed, the generation unit 13c can also generate information about a customer referral fee to be charged to the beauty salon or stylist according to the number of users U.

[0077] The generating unit 13c acquires the compatibility information from the compatibility information storage unit 12c, and stores the generated provided information in the provided information storage unit 12d.

[0078] (2-3-4. Transmitting unit 13d) The transmitting unit 13d transmits the information to be provided generated by the generating unit 13c to the user U. For example, the transmitting unit 13d transmits to the user terminal 20 of the user U an image including a hair style whose compatibility with an article of clothing selected by the user U is equal to or greater than a predetermined threshold. At this time, the transmitting unit 13d may transmit, together with the image including the hair style, images of beauty salons, stylists, etc. that can provide the hair style, as well as business information such as available appointment dates.

[0079] The transmitting unit 13d acquires the provided information from the provided information storage unit 12d. The transmitting unit 13d may also transmit the provided information to the website server 30 or a business terminal / database (not shown). For example, when a user U makes a reservation at the beauty salon or the like and the treatment is actually performed, the transmitting unit 13d may transmit information regarding a customer referral fee to be charged to the beauty salon or the like or the stylist.

[0080] (2-3-5. Learning section 13e) The learning unit 13e learns the machine learning model so as to output the compatibility of each hair style with the clothing item when the product information and style information selected by the user U are input. At this time, the learning unit 13e may learn the machine learning model by backpropagation or the like.

[0081] For example, the learning unit 13e trains the machine learning model so that when information indicating that the combination of a clothing item selected by user U and a hair style is compatible is input to the machine learning model for each user U, the attributes of user U, and the situation of user U, the compatibility of the hair style with the clothing item is output as a number approaching "1."

[0082] On the other hand, the learning unit 13e trains the machine learning model so that when information indicating that the combination of the clothing item selected by user U and the hair style is incompatible is input to the machine learning model for each user U, the attributes of user U, and the situation of user U, the compatibility of the hair style with the clothing item is output as a number approaching "0".

[0083] [3. Specific examples of information provision processing] Next, a specific example of the information provision process according to the embodiment will be described. Below, the learning process of the machine learning model and the process of generating the information to be provided will be described, and then a specific example of the information to be provided that is transmitted to the user terminal 20 of the user U will be described.

[0084] (3-1. Learning process of machine learning model) The learning process of the machine learning model according to the embodiment will be described. By executing this process, the information providing device 10 can generate a trained machine learning model to be used in the process of generating information to be provided, which will be described later. Below, the supervised data collection process, image data extraction process, and image data learning process will be described in this order.

[0085] (3-1-1. Correct data collection process) First, the information providing device 10 collects correct data from SNS. Here, the collected correct data is, for example, an image in which a hairstyle and clothing are photographed at the same time, and an image whose evaluation satisfies a predetermined condition. More specifically, the collected correct data is an image posted by a predetermined person, an image with more than a predetermined number of "likes," an image with more than a predetermined number of comments or favorable content, etc. Similarly, the information providing device 10 can also collect correct data from moving images such as television commercials and movies.

[0086] (3-1-2. Image data extraction process) Next, the information providing device 10 extracts hair parts and clothing parts (e.g., body parts, belongings) from the collected correct answer data image. At this time, the information providing device 10 may extract clothing parts by tops, bottoms, accessories, bag, etc.

[0087] (3-1-3. Image data learning processing) Then, the information providing device 10 trains the machine learning model so that when a combination of an image of a hair part and an image of each clothing part extracted from the same image (i.e., a combination that is likely to be well-rated) is input, the machine learning model outputs information indicating a high compatibility (e.g., a score of 1). Furthermore, when a combination of an image of a hair part and an image of a clothing part extracted from a different image (i.e., a combination that is not known to be well-rated) is input, the information providing device 10 trains the machine learning model so that the model outputs information indicating a low compatibility (e.g., a score of 0 or a random number equal to or less than a predetermined value (0.7)). Through the above-described processing, the information providing device 10 generates a machine learning model that has learned the above-described set matching.

[0088] (3-2. Generation process of provided information) The process of generating information to be provided according to the embodiment will be described below. By executing this process, the information providing device 10 can provide hairstyles posted by hairdressers, and when a user U selects a hairstyle, it can provide a reservation service for the beauty salon to which the selected hairdresser belongs (hairdresser reservation service). Below, the product information acquisition process, candidate information generation process, aspect identification process, and provided information transmission process will be described in this order.

[0089] (3-2-1. Product information acquisition process) First, the information providing device 10 is a server that provides information about, for example, beauty salons. On the other hand, the website server 30 is a server for a website that is, for example, an e-commerce site for clothing and accessories. Here, a user U refers to the website that is an e-commerce site for clothing and accessories. At this time, the website server 30 transmits an image of the product (clothing) that the user U has searched for and selected to the information providing device 10. That is, through the above-described process, the information providing device 10 acquires an image (item information) of the clothing and accessories selected by the user U.

[0090] (3-2-2. Candidate information generation process) Next, the information providing device 10 generates an image by cutting out the product portion from the acquired image, and generates candidate information by combining each hairstyle with the image cut out from the product portion. At this time, the information providing device 10 may accept the hairstyle image (style information) from each hairdresser, or may acquire it from the style information database 40 that collects hairstyle images.

[0091] (3-2-3. Mode Identification Processing) Next, the information providing device 10 inputs each of the generated candidate information into the machine learning model, and identifies hairstyles included in the candidate information whose output scores exceed a predetermined threshold. That is, through the above-described process, the information providing device 10 identifies hair styles that are highly compatible with the clothing item selected by the user U.

[0092] (3-2-4. Provision information transmission process) Then, the information providing device 10 generates information to be provided by adding a link to a reservation page to the image of the identified hairstyle, and transmits one or more pieces of generated information to the website server 30. As a result, the website server 30 can provide the user U with information such as, "Here is a hairstyle that goes well with this outfit. Would you like to make a reservation?" At this time, the information providing device 10 can also transmit the information to be provided directly to the user terminal 20 of the user U.

[0093] (3-3. Specific examples of information provided) A specific example of the information to be provided according to the embodiment will be described with reference to Fig. 7. Fig. 7 is a diagram showing a specific example of the information providing process according to the embodiment. Below, a specific example of the information to be provided that is transmitted to and displayed on the user terminal 20 of the user U will be described.

[0094] (3-3-1. Display screen W1) First, we will explain the display screen W1 related to clothing or other accessories selected by user U as information to be displayed on user terminal 20 of user U. Display screen W1 displays an image I1 of a dress (item I), which is the accessory selected by user U on the EC site, and a screen I2 including the product name, price, available sizes and colors of the accessory, as well as an "Add to Cart" button for transitioning to a purchase screen. At this time, user U can view information about hairstyles and beauty salons on display screen W2, which will be described later, and then decide whether or not to purchase the dress.

[0095] (3-3-2. Display screen W2) Next, we will explain the display screen W2, which contains information displayed on the user terminal 20 of the user U, such as hair styles and other hair styles corresponding to the clothing and accessories selected by the user U, as well as business information such as beauty salons. The display screen W2 displays hairstyle images H1, H2, and H3 as "hairstyles that go well with this item," along with screens B1, B2, and B3 showing information about beauty salons X, Y, and Z that offer each hairstyle. By clicking on the hairstyle images H1, H2, and H3, the user U can view an enlarged image of each hairstyle or details about the hairstyle. Furthermore, by clicking on screens B1, B2, and B3 showing information about beauty salons X, Y, and Z, the user U can view information about each beauty salon and its associated hairdresser, or transition to a screen for making a reservation at the beauty salon.

[0096] [4. Information provision process flow] The procedure of information processing of the information providing device 10 according to the embodiment will be described with reference to Fig. 8.

The secondary storage device 1050 may be an internal storage device or an external storage device. The secondary storage device 1050 may also be a removable storage medium such as a USB memory or an SD (Secure Digital) memory card. The secondary storage device 1050 may also be cloud storage (online storage), a NAS (Network Attached Storage), a file server, or the like.

[0116] The output I / F 1060 is an interface for transmitting information to be output to an output device 1010 that outputs various types of information, such as a display, a projector, a printer, etc., and is realized by a connector conforming to a standard such as USB (Universal Serial Bus), DVI (Digital Visual Interface), or HDMI (High Definition Multimedia Interface), etc. The input I / F 1070 is an interface for receiving information from various input devices 1020, such as a mouse, a keyboard, a keypad, a button, a scanner, etc., and is realized by a USB, etc.
