[1-2. Select search conditions from image analysis results]
The information providing device 100 analyzes the images linked to the property and creates search conditions based on the object in the image and the characteristics of the image or object obtained as a result of the analysis of the image or object. (search conditions) and present them to the user.

For example, if the object of the image is an "image of the exterior" and the number of user views/browsing time for that image is large, the information providing apparatus 100 selects the search condition "property with popular exterior". Further, when the object of the image is an "image of a view" and the aesthetic score of the image is high, the information providing device 100 selects the search condition "property with a beautiful (good) view".

In addition, the information providing device 100 is configured such that the object of the image is an "image of a water area" such as a kitchen, toilet, bathroom, or washroom, and the image has a high aesthetic score and is viewed by a large number of users. If so, select the search condition ``properties with clean plumbing.'' At this time, the information providing device 100 specifically identifies the target object in the image that the user is viewing, and selects "property with a clean kitchen," "property with a clean toilet," and "property with a clean bathroom." Alternatively, search conditions such as "properties with clean washrooms" may be selected. That is, there are categories such as kitchen, toilet, bathroom, washroom, etc., and there is also a higher-level category "Water area", and it is possible to select search conditions for each category.

Alternatively, if the object of the image is a "storage image" such as a closet, closet, trunk room, etc., and the number of views by the user is large, the information providing device 100 selects the search condition "property with ample storage". Good too. Furthermore, if the image has a high aesthetic score and has been viewed by many users, the information providing device 100 may select the search condition of "property with beautiful storage."

Furthermore, if the object of the image is an "image of the exterior" or "image of the interior" of a used property, the aesthetic score of the image is high, and the number of views by the user is large, the information providing device 100 displays " You may also select the search condition "Properties that have been renovated within the past three years."

Note that the information providing apparatus 100 may classify images into "beautiful", "cool", etc. through crowdsourcing or the like, and may reflect this as the name of the search condition. For example, the information providing apparatus 100 may have the user manually classify images into "beautiful", "cool", etc., and may reflect this as the name of the search condition. Further, the information providing device 100 may aggregate the tags (or labels) such as "beautiful" and "cool" specified by each user for the image, and classify the tags into the category of the tag specified most frequently. Further, the information providing device 100 may combine word-of-mouth information about the property and comments from the trader and weight the certainty of the feature (adding points if the property has a "good view", etc.).

[1-3. Creation of property list based on aesthetic score]
The information providing device 100 analyzes images linked to properties and determines properties to be listed based on the object in the image and the aesthetic score of the image. For example, the information providing device 100 uses a model to select images that correspond to the "property appearance", takes the aesthetic score of each, and selects properties with images with high scores (within top XXX, above a threshold, etc.). The property to be listed. At this time, the information providing apparatus 100 uses the learning model to output the aesthetic score of the image of the property that corresponds to the search condition.

Properties to be listed include, for example, "properties with cool exteriors," "properties with beautiful views," "properties with beautiful plumbing," and "properties that have been renovated within the past three years."

It should be noted that relatively more properties that are 30 years old or older have low aesthetic scores. Additionally, properties that are over 30 years old may be avoided even if they have a high aesthetic score. Therefore, the information providing device 100 may exclude properties that are 30 years old or older regardless of the aesthetic score. In this case, the information providing device 100 obtains information that the property is 30 years or older from the property information of the property or by combining information included in the property information. Furthermore, regarding the aesthetics of an object, things such as "beautiful" based on an individual's sense (subjectivity) may be defined by a person, regardless of the aesthetic score.

(Aesthetic score according to this embodiment)
As the aesthetic score according to the present embodiment, the information providing device 100 calculates a score that takes into account both the technical aspects (image quality, etc.) and the aesthetic aspects (image content, etc.) of the image of the property, unlike conventional methods. . The aesthetic score according to this embodiment takes a value of 1 to 10. Although it depends on the domain of the data, as a guideline for the aesthetic score, 5.0 or less is considered low, and 5.5 or more is considered high. Note that if it is greater than 5.0 and less than 5.5, it is determined to be normal. The aesthetic score according to this embodiment is assumed to be used when it is desired to select only high-quality images from an unspecified number of images.

In this way, the information providing device 100 performs image analysis of properties and automatically generates classifications of properties such as those with cool appearance. That is, the information providing apparatus 100 performs category classification of images. For example, the information providing device 100 classifies images of properties into categories such as "water area", "exterior", "view", "cool", and "beautiful".

At this time, the information providing device 100 evaluates the "cleanliness of water areas", "beautiful appearance", etc. of the classified images based on the aesthetic score related to "cleanliness", and groups the evaluation results. The property is then proposed to the user as a "property with beautiful properties." As a result, the information providing device 100 can provide properties with good cost performance, such as properties with clean plumbing such as kitchens even though they are used properties. The information providing device 100 determines what property images to classify into what kind of property based on rules.

Furthermore, when presenting an image of the exterior of a property, for example, the information providing device 100 excludes images of the exterior of a property that is 30 years old or older from being presented. The property may be a single-family house or a rental condominium/apartment.

Furthermore, if the information providing device 100 is old and has a poor exterior aesthetic score but a high interior aesthetic score, it is determined that the value of renovation is high. The information providing device 100 can suggest a property as a recommended property if the property has a high renovation value and the rent etc. are lower than the market price due to the age of the property. Furthermore, the information providing device 100 can perform a relative evaluation of each part of each property, such as whether the interior is clean or the kitchen and other plumbing areas are clean.

At this time, the information providing device 100 determines whether to classify the image based on the relative difference in aesthetic scores. Note that the information providing device 100 may calculate the aesthetic score using the image of the property as it is, or may apply lens correction to the image of the property to calculate the aesthetic score in its actual state.

Note that the information providing device 100 creates a model for estimating and classifying a category for each property image based on a combination of the property image and a category (for example, “beautiful exterior”) resulting from the image classification. / May be updated. Further, the information providing apparatus 100 may create a model for each attribute of the target property or for each user attribute. Furthermore, the information providing device 100 may create a model that outputs the aesthetic score of the image when an image is input.

Furthermore, the information providing device 100 estimates the user's preference conditions based on the commonality of characteristics (for example, "beautiful exterior") of properties that the user often views (frequently), and calculates the estimated preference conditions. Suggest properties that match your criteria.

For example, the information providing device 100 determines "location", "tower apartment", "rent/price", "5th floor", "location", "tower apartment", "rent/price", "5th floor It estimates whether the user is interested in the following, ``Has a garden,'' ``Size of balcony,'' ``Year of construction,'' etc. Alternatively, the information providing device 100 estimates whether the user is interested in "water" as a feature of each part of the property.

Then, the information providing device 100 displays an image of the appearance of the property when the user is interested in the entire property (the property itself), or an image of that part when the user is interested in a specific part (part) of the property. Present beautiful properties (properties with high aesthetic scores).

Further, the information providing device 100 may propose an AND condition (combination) of tags. For example, if the information providing device 100 estimates that the user is interested in the "bath" and "exterior" of the property from the image of the property that the user is viewing, the information providing device 100 may determine that the "bath" and "exterior" are both beautiful. Suggest properties.

Furthermore, the information providing apparatus 100 may increase the threshold value for determining a property to be proposed. For example, if the information providing device 100 estimates that the user is interested in "clean restrooms," it sets the aesthetic score threshold for "toilet" higher than normal (or average) and suggests properties that are higher than the threshold value. You can do it like this.

(Control unit 130)
Returning to FIG. 4, the explanation will be continued. The control unit 130 is a controller, and uses, for example, a CPU (Central Processing Unit), an MPU (Micro Processing Unit), an ASIC (Application Specific Integrated Circuit), or an FPGA (Field Programmable Gate Array) to control the information providing apparatus 100. This is achieved by executing various programs (corresponding to an example of an information processing program) stored in an internal storage device using a storage area such as a RAM as a work area. In the example shown in FIG. 4, the control unit 130 includes an acquisition unit 131, a calculation unit 132, a totaling unit 133, a determination unit 134, and a provision unit 135.

(Acquisition unit 131)
The acquisition unit 131 acquires a search query input by the user U. For example, when the user U inputs a search query into a search engine or the like and performs a keyword search, the acquisition unit 131 acquires the search query via the communication unit 110. That is, the acquisition unit 131 acquires, via the communication unit 110, a keyword input by the user U into a search window of a search engine, site, or application.

Further, the acquisition unit 131 acquires an image of the property via the communication unit 110. For example, the acquisition unit 131 receives, via the communication unit 110, posting of images of properties from real estate agents and the like who buy, sell, exchange, rent, manage, and act as agents or intermediaries for real estate. Alternatively, the acquisition unit 131 receives, from the terminal of the user U, an image of a property owned by the user U or a designation of an image of a property that the user U is interested in via the communication unit 110. , obtain images of those properties. Note that the image of the property may be an image of a specific part (site) of the property.

The acquisition unit 131 also acquires user information regarding the user U via the communication unit 110. For example, the acquisition unit 131 acquires identification information indicating the user U (user ID, etc.), location information of the user U, attribute information of the user U, etc. from the terminal device 10 of the user U. Further, the acquisition unit 131 may acquire identification information indicating the user U, attribute information of the user U, etc. at the time of user U's user registration. The acquisition unit 131 then registers the user information in the user information database 121 of the storage unit 120.

Further, the acquisition unit 131 acquires various types of history information (log data) indicating the behavior of the user U via the communication unit 110. For example, the acquisition unit 131 acquires various types of history information indicating the behavior of the user U from the terminal device 10 of the user U or from various servers based on the user ID or the like. The acquisition unit 131 then registers various types of history information in the history information database 122 of the storage unit 120.

(Calculation unit 132)
The calculation unit 132 calculates the aesthetic score of the image linked to the property.

Further, the calculation unit 132 may calculate the aesthetic score of the image of only the property viewed by the user.

(Tally unit 133)
The aggregation unit 133 aggregates the characteristics of properties viewed by the user. For example, the tallying unit 133 extracts points of interest from images of properties viewed by the user, tags them as features of the image, and tallies tags indicating features of the images viewed by the user. Then, the aggregation unit 133 estimates the commonality of the features of the images that the users are viewing.

Note that the aggregation unit 133 also functions as a specifying unit that specifies a tendency of images (or a tendency of image characteristics) whose viewing mode satisfies a predetermined condition among images registered for each property. Further, the identification unit (aggregation unit 133) identifies the aesthetic score of the image viewed by the user. For example, the identification unit (aggregation unit 133) identifies a “tendency” of images that are frequently viewed, such as “water areas” being more common and “balconies” being more common. Alternatively, the identification unit (aggregation unit 133) identifies trends in information such as “water area”, “balcony”, “aesthetic score”, etc. that accompany the image. The aesthetic score of the image may be an aesthetic score assigned to the image in advance (for example, an existing aesthetic score set by another system, etc.). Furthermore, the aggregation unit 133 also functions as an extraction unit that extracts the characteristics of each property image from an unspecified number of property images, regardless of whether the user has viewed the images.

Further, the aggregation unit 133 may create/update a model that estimates and classifies categories for each property image. For example, the aggregation unit 133 performs machine learning using the property image and the category of the image as input data, and creates/updates a model that estimates and classifies the category of the property image. Furthermore, the aggregation unit 133 may create a model that outputs the aesthetic score of the image when an image is input.

(Decision unit 134)

That is, the determining unit 134 selects an image according to the tag using the model, and determines as a property to be listed a property whose aesthetic score of the selected image satisfies a predetermined condition. Further, the determining unit 134 uses the learning model to output the aesthetic score of the image of the property that corresponds to the search condition.

Further, if it is estimated that the user is interested in a specific part of the property based on the object in the image of the property viewed by the user, the determining unit 134 lists the property according to the search condition regarding the specific part. The property is determined to be For example, if it is estimated that the user is interested in the exterior of the property based on the object in the image of the property that the user has viewed, the determining unit 134 selects a property that meets the search conditions regarding the visual aspect of the exterior. Decide as a property to list. Furthermore, when listing properties according to the search conditions regarding the visual appearance of the exterior, the determining unit 134 excludes properties whose building age is equal to or greater than a predetermined threshold (for example, properties that are 30 years old or older) from the list. do. Further, when it is estimated that the user is interested in the plumbing of the property based on the object in the image of the property viewed by the user, the determining unit 134 lists properties that meet the search conditions regarding the plumbing. Determine as. Further, if it is estimated that the user is interested in storage of the property based on the object in the image of the property viewed by the user, the determining unit 134 determines the property that meets the search conditions regarding storage as the property to be listed. do.

At this time, the determining unit 134 selects an image corresponding to a specific part of the property using the model, and lists properties with images with high scores based on the aesthetic score of the image of the selected specific part. It may be determined as

For example, the determining unit 134 uses a model to select an image that corresponds to the exterior of the property, and based on the aesthetic score of the selected exterior image, determines the property with the image with the highest score as the property to be listed. At this time, when determining a property to list based on the aesthetic score of the image of the exterior of the property, the determining unit 134 selects a property whose building age is at least a predetermined threshold (for example, a property which is 30 years old or older). Exclude from target.

Further, the determining unit 134 selects images corresponding to the water area of the property using the model, and determines the property with the image with the top score as the property to be listed based on the aesthetic score of the selected image of the water area. .

Further, the determining unit 134 uses the model to select an image corresponding to a storage property, and based on the aesthetic score of the selected storage image, determines the property of the image with the top score as the property to be listed.
