(1-1. Agent function)
An agent function, which is one of information processing according to the embodiment, will be described below. The agent function is an extended function that provides information on properties that match search conditions specified by the user from a perspective different from the user's search conditions. Hereinafter, the flow of using the agent function according to the embodiment will be described with transition of images displayed on the terminal device 10 . FIG. 2 is a diagram illustrating an example of image display on the terminal device according to the embodiment. The processing by the terminal device 10 shown in FIGS. 1 and 2 is implemented by a dedicated application or the like pre-installed in the terminal device 10 in order to use the information providing service provided by the information processing device 100. FIG.

When the terminal device 10 receives from the user U01 designation of search conditions for specifying a property, the terminal device 10 transmits the search conditions designated by the user U01 to the information processing apparatus 100. FIG. The search conditions include search keywords, areas, routes or stations, other basic conditions, and detailed conditions other than the basic conditions. The basic conditions include conditions such as rent, floor plan, exclusive area, walking time from the nearest station, property type, building age, building age, property type, and the like. Further, detailed conditions include building structure, bathrooms and toilets, kitchens, storage, verandas, security, facilities, parking and bicycle parking lots, number of floors, fixtures, communication, occupancy conditions, etc. includes the conditions of

Upon receiving the search conditions from the terminal device 10, the information processing device 100 searches for property information that matches the search conditions, and provides the property information to the user U01 by transmitting the searched property information to the terminal device 10 ( step S11).

For example, as shown in FIG. 2, on the terminal device 10, the property information received from the information processing device 100 is displayed in a search result display window W1 as a search result. The search result display window W1 includes property information on properties that match the search conditions, a condition change button BT1 for changing the search conditions, an agent function use button BT2 for using the agent function, and the like.

Further, for example, as shown in FIG. 2, in the terminal device 10, a pop-up window W2 about the agent function is superimposed on the search result display window W1 in response to the operation of the agent function use button BT2. The pop-up window W2 includes an explanation of the agent function, a confirmation button BT3 for accepting a final confirmation from the user U01 as to whether or not to use the agent function, and the like. When the terminal device 10 detects that the confirmation button BT3 has been operated, the terminal device 10 transmits a request to use the agent function to the information processing device 100 .

Returning to FIG. 1, when the information processing apparatus 100 receives a request for use of the agent function from the terminal device 10, the information processing apparatus 100 searches for multiple properties (an example of a “transaction target”) that match the search conditions for each of multiple evaluation axes. A property evaluation score for evaluation is calculated (step S12).

Subsequently, the information processing apparatus 100 selects properties for each of the plurality of evaluation axes based on the calculated property evaluation scores (step S13). Then, the information processing device 100 provides the user U01 with information on the property selected based on the property evaluation score by transmitting property information, which is information on the selected property, to the terminal device 10 (step S14).

For example, as shown in FIG. 2, on the terminal device 10, the property information provided to the user U01 by using the agent function is displayed in the window W3 corresponding to the agent function. In the window W3 corresponding to the agent function shown in FIG. 2, a plurality of items of property information are displayed in association with a plurality of evaluation axes. In addition, the window W3 corresponding to the agent function shown in FIG. Heading information indicating "location/environment", which is one of the axes, is displayed.

(1-1-1. Property evaluation score)
A method of calculating a property evaluation score for evaluating a property for each of a plurality of evaluation axes will be described below. FIG. 3 is a diagram showing an outline of a method for calculating a property evaluation score according to the embodiment. FIG. 3 illustrates a method of calculating the score for the condominium EX1 included in a plurality of properties that match the search conditions.

The information processing apparatus 100 collects review information (so-called word-of-mouth information) posted on each property from a plurality of service users through the information providing service, and records the collected review information. As shown in FIG. 3, the review information includes score information and comment information posted by the service user for each viewpoint in association with the posting date and time.

The information processing apparatus 100 can use the viewpoints included in the collected review information as a plurality of evaluation axes used as property evaluation indices. For example, as shown in FIG. 3, the information processing apparatus 100 can use "building/room" and "location/environment" included in the review information as evaluation axes. Further, the information processing apparatus 100 may use information derived from the viewpoint included in the review information as an evaluation axis.

In addition, the information processing apparatus 100 aggregates the review information for each evaluation axis, and calculates a property evaluation score for evaluating each property that matches the search condition for each of the plurality of evaluation axes based on the plurality of evaluation elements. do. The evaluation elements include points, the number of posted comments, the number of comment characters, the number of positive words, user attributes, freshness of posts, and the number of users. Note that the evaluation elements may include elements other than those shown in FIG. In this way, the information processing apparatus 100 can calculate an unbiased composite score based on various factors.

The score corresponds to the information of the score given by the service user for each viewpoint for the target property. The number of posted comments corresponds to information on the number of comments posted by service users for each viewpoint regarding the target property. The comment character count corresponds to information on the character count of the comment posted for each viewpoint regarding the target property. The number of positive words corresponds to the number of positive expressions included in comments posted to service users for each point of view. The user attribute corresponds to information on the attribute of the user who posted the review information. Posting freshness corresponds to a time stamp (date and time information) when review information is posted. The number of users corresponds to the number of users for each viewpoint who posted reviews.

Of the evaluation factors described above, the number of comment characters, the number of positive words, the user attribute, and the post freshness are converted into coefficients as weighting factors for weighting the score.

Regarding the number of characters in the comment, for example, when the number of characters is 50 or more, the number of characters can be converted into a coefficient by replacing it with coefficient information preset in association with the number of characters, such as a coefficient of 1.5.

Regarding the number of positive words, if the number of occurrences of positive expressions included in the comment is 5, the coefficient information preset in association with the number of occurrences of positive expressions, such as a coefficient of 1.3, is used. It can be factorized by replacing.

Note that the coefficient information associated in advance with the number of positive words may be changed according to the user. For example, the information processing apparatus 100 pre-labels the property information to be provided to the service user via the agent function corresponding window W3. For the label given to the property information, for example, positive expressions for the property can be arbitrarily extracted from review information. Examples of labels include "Good Manners of Residents", "Enriched Facilities", and "Good Management and Cleaning". The information processing apparatus 100 receives an evaluation of the property from the service user for each property information via the window W3 corresponding to the agent function. The information processing apparatus 100 also records the evaluation of the property information for each service user in association with the label attached to the property information. Then, the information processing apparatus 100 specifies the number of positive words based on the positive words corresponding to the service user when calculating the property evaluation score described above for each evaluation axis. In this way, the information processing apparatus 100 can adjust the evaluation of the positive expression included in the comment according to the user.

Regarding the user attribute, if only one resident of the property to be scored is included among the review posters (for example, users with user IDs “U001” and “U002” shown in FIG. 3), the coefficient It can be converted to a coefficient by replacing it with coefficient information that is preset in association with information about user attributes, such as 1.5.

Regarding post freshness, if all posts are made in the current year, it is converted to a coefficient by replacing it with coefficient information preset in association with the time stamp (date and time information), such as a coefficient of 1.0. can.

Note that the method of converting the evaluation factors into coefficients is not limited to the example described above, and any method can be used. In addition, for the above-mentioned evaluation elements, for example, there is an upper limit such as score, and the corresponding value falls within a certain range, and the corresponding value does not fall within a certain range, such as the number of comments. Contains possible elements. Therefore, the information processing apparatus 100 may standardize the values corresponding to all the evaluation factors using the Z value or the like so that all the evaluation factors can be scored using the same scale.

In addition, the information processing apparatus 100 calculates scores using different evaluation logics for each evaluation axis. For example, the evaluation logic can be changed by changing the coefficient information associated with the above-described evaluation factors for each evaluation axis. Thereby, the information processing apparatus 100 can calculate an appropriate score for the transaction object for each evaluation axis.

Then, the information processing apparatus 100 calculates the property evaluation score for each evaluation axis for the property to be scored, for example, by multiplying the values corresponding to the plurality of evaluation elements. For example, in FIG. 3, for the property to be scored "Mansion EX1", the property evaluation score corresponding to the comprehensive evaluation, the property evaluation score corresponding to "building/room", and the property evaluation score corresponding to "location/environment" A property evaluation score and the like are shown. Note that the overall evaluation corresponds to the sum of scores corresponding to each evaluation axis. In this manner, the information processing apparatus 100 performs scoring for all properties that match the search conditions.

Further, the information processing apparatus 100 may select property information of a property whose property evaluation score is equal to or higher than a predetermined threshold from among a plurality of properties that match the search condition. Thereby, the information processing apparatus 100 can select useful information for the service user.

(1-1-2. Posting method of property information)
A method of displaying property information selected based on property evaluation scores will be described below. After calculating the score for each evaluation axis, the information processing apparatus 100 selects a property for each of the plurality of evaluation axes from among the plurality of properties that match the search condition based on the calculated score. Then, the information processing apparatus 100 provides the user U01 of the terminal device 10 with list information in which the property information of the selected property is associated with each of the headline information indicating a plurality of evaluation axes. Thereby, the information processing apparatus 100 can provide the service user with information on the transaction object in an easy-to-understand manner.

The information processing apparatus 100 may rearrange the display position of the headline information indicating the evaluation axis based on the user context of the user U01 who is the provision destination when displaying the property information in the list information. For example, the information processing apparatus 100 can estimate the search conditions that the user U01 of the provision destination attaches importance to when searching for properties, based on the search history when searching for properties using the information providing service. For example, it can be estimated that the more frequently a condition is used as a search condition, the more important it is. In addition, for example, the index corresponding to the sorting method that is selected frequently when sorting the display order of search results (for example, "highest evaluation", "latest posting date", etc.) ), it can be estimated that the more important the conditions are.

Then, for example, when the agent function-compatible window W3 supports upward scrolling, the information processing apparatus 100 shifts the evaluation axis corresponding to the search condition of importance to the agent function-compatible window W3 and the other evaluation axes. Change the display position of the heading information from the default position so that it is displayed relatively higher than For example, in the example shown in FIG. 2, in the window W3 corresponding to the agent function displayed on the terminal device 10, headline information indicating "comprehensive evaluation", which is one of the evaluation axes, is displayed at the top. In the example shown in FIG. 2, under the heading information of "Comprehensive Evaluation", heading information indicating "Building/Room", which is one of the evaluation axes, is displayed. In the example shown in FIG. 2, the headline information of "location/environment", which is one of the evaluation axes, is displayed under the headline information of "building/room". When it is difficult to specify the context of the user U01 due to insufficient data samples or the like, the information processing apparatus 100 can determine the display position of the headline position indicating the evaluation axis at a predetermined default position. In this manner, the information processing apparatus 100 can provide property information in accordance with the service user's tendency to search, hobbies, and preferences.

In addition, the information processing apparatus 100 displays headline information indicating an evaluation axis for which the difference between the highest score and the lowest property evaluation score calculated for each evaluation axis is equal to or greater than a predetermined threshold among the plurality of evaluation axes. It may be posted with priority. Thereby, the information processing apparatus 100 can present to the user an evaluation axis having a difference between pieces of property information as much as possible.

Further, when displaying the property information of the selected property in association with each of the plurality of heading information indicating the evaluation axis, the information processing apparatus 100 associates the property information with the heading information indicating the evaluation axis based on the property evaluation score. The display positions of the property information to be displayed may be rearranged. For example, when the information processing apparatus 100 is configured to be browseable by moving the property information displayed in the list information in the left direction (when it supports left scrolling), the higher the property evaluation score, the higher the property information of the property. The display position is changed so that it is displayed on the left relative to the property information of other properties toward the window W3 corresponding to the agent function. The information processing apparatus 100 can arbitrarily determine the display position of the property information according to the scroll direction when viewing the property information. Thereby, the information processing apparatus 100 can present property information in order from, for example, property information presumed to be useful to the service user.

(1-2. Property selection based on trend of rent trends)
Further, when the information processing apparatus 100 selects a property to be displayed in the list information described above from among a plurality of properties that match the search conditions specified by the user U01, the rent associated with each of the plurality of properties (" Based on the results of comparing trends in trends in average rents calculated from "amounts tied to each transaction target" and trends in trends in rents for each property, properties that meet prescribed conditions are selected. good too. In this way, the information processing apparatus 100 can provide the user with useful information for evaluating the property information by selecting the property information based on the tendency of the price transition.

An example of a property selection method based on rent transition trends will be described below with reference to FIG. FIG. 4 is a diagram illustrating an example of rent transitions according to the embodiment. In FIG. 4, the transition of the past average rent of a plurality of properties in the target region (area) specified as the search condition by the user U01 and the transition of the past rent of the target property to be scored are shown in a comparable manner. It is

The information processing device 100 provides financial benefit to the service user based on the comparison result between the average rent increase rate in the most recent fixed period and the rent increase rate in the most recent fixed period for each property to be scored. properties can be selected. Specifically, with reference to the example shown in FIG. 4, the information processing apparatus 100 calculates the average rent increase rate in the target area based on the average rent from 2015 to 2021. Further, as shown in FIG. 4, the information processing apparatus 100 calculates the rent increase rate of the target property based on the rent from 2015 to 2021.

Next, the information processing apparatus 100 compares, for example, the average rent increase rate in the target area shown in FIG. 4 with the rent increase rate of the target property shown in FIG. As a result of the comparison, if the rent increase rate of the target property shown in FIG. 4 is lower than the average rent increase rate in the target area shown in FIG. Select as a property that is economically beneficial to That is, the information processing apparatus 100 selects the target property shown in FIG. 4 as a property with a relatively low rent. As a result, the information processing apparatus 100 can individually select property information that is advantageous in terms of money from among a plurality of transaction targets that match the search conditions, using the increase rate of the money as a criterion.

Alternatively, the information processing apparatus 100 may determine the average rent decrease rate in the most recent fixed period regarding a plurality of properties that match the search condition specified by the user U01, and the rent decrease rate in the most recent fixed period for each property to be scored. Based on the result of comparison with, the service user can select a property that is profitable in terms of money.

Specifically, with reference to the example shown in FIG. 4, the information processing apparatus 100 calculates the average rent decrease rate in the target area based on the average rent from 2015 to 2021. In addition, as shown in FIG. 4, the information processing apparatus 100 calculates the rent decrease rate of the target property based on the rent from 2015 to 2021.

Next, the information processing apparatus 100 compares, for example, the average rent decrease rate in the target area shown in FIG. 4 with the rent decrease rate of the target property shown in FIG. As a result of the comparison, if the rent decrease rate of the target property shown in FIG. 4 is larger than the average rent decrease rate in the target area shown in FIG. Select as a property that is economically beneficial to That is, the information processing apparatus 100 selects the target property shown in FIG. 4 as a property with a relatively low rent. As a result, the information processing apparatus 100 can individually select a transaction target having a superior monetary value from among a plurality of transaction targets that match the search condition, using the declining rate of the amount as a criterion. In addition, when the information processing device 100 selects a property using the above-described drop rate as an evaluation index of a property that is financially beneficial to the service user, even if the drop rate is a predetermined threshold or more as a condition good.

Note that the information processing apparatus 100 may use an index obtained by normalizing the average rent when calculating the rate of increase or decrease of the average rent in the target area. Similarly, the information processing apparatus 100 may use an index obtained by normalizing the rent of the target property when calculating the rate of increase or decrease of the rent of the target property.

Then, the information processing apparatus 100 displays list information in which the property information of the property selected as the property that is financially beneficial to the service user is associated with the headline information indicating that the property is financially beneficial to the service user. offer. Thereby, the information processing apparatus 100 can provide the user with useful information in an easy-to-understand manner. FIG. 5 is a diagram showing another example of image display on the terminal device according to the embodiment.

In the example shown in FIG. 5, instead of the headline information indicating the "comprehensive evaluation", headline information indicating that the service user is profitable in terms of money (for example, "value property in terms of rent change") is displayed. The point displayed on the terminal device 10 is different from the example shown in FIG. In the same manner as in the method of posting property information described above, the information processing apparatus 100 displays headline information indicating an evaluation axis based on the user context of the user U01 who is the provision destination when posting property information in the list information. You can rearrange the positions.

In addition, when displaying the property information of the selected property in association with headline information indicating that it is financially beneficial to the service user, the information processing apparatus 100 does not depend on the magnitude of the financial benefit to the service user. Based on this, the display positions of the property information displayed in association with the headline information may be rearranged. For example, when the information processing apparatus 100 is configured so that property information displayed in the list information can be browsed by moving it in the left direction (if it supports left scrolling), the information processing apparatus 100 can select properties that are highly profitable for the service user in monetary terms. The display position of property information is changed so that it is displayed on the left relative to the property information of other properties toward the window W3 corresponding to the agent function. The information processing apparatus 100 can arbitrarily determine the display position of the property information according to the scroll direction when viewing the property information.

As described above, the information processing apparatus 100 according to the embodiment can provide the user with useful information for evaluating properties that are transaction targets.
