(1-1. Agent function)
Hereinafter, the agent function, which is one of the information processing according to the embodiment, will be described. The agent function is an extended function that provides property information from a different perspective from the user's search conditions for property information that matches the search conditions specified by the user. Hereinafter, the flow of using the agent function according to the embodiment will be described with reference to the transition of the image displayed on the terminal device 10. FIG. 2 is a diagram showing an example of an image display in the terminal device according to the embodiment. The processing by the terminal device 10 shown in FIGS. 1 and 2 is realized by a dedicated application installed in advance in the terminal device 10 in order to use the information providing service provided by the information processing device 100.

When the terminal device 10 receives the designation of the search condition for specifying the property from the user U01, the terminal device 10 transmits the search condition specified by the user U01 to the information processing device 100. The search conditions include search keywords, areas, lines or stations, other basic conditions, and detailed conditions other than the basic conditions. The basic conditions include conditions such as rent, floor plan, occupied area, time on foot from the nearest station, property type, age, age, and property type. In addition, detailed conditions include building structure, bathroom and toilet, kitchen, storage, veranda, security, equipment, parking lot and bicycle parking lot, number of floors, equipment, communication, occupancy conditions, etc. Conditions are included.

When the information processing device 100 receives the search condition from the terminal device 10, the information processing device 100 searches for the property information that matches the search condition, and sends the searched property information to the terminal device 10 to provide the property information to the user U01. Step S11).

For example, as shown in FIG. 2, the terminal device 10 displays the property information received from the information processing device 100 as the search result in the search result display window W1.

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

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

For example, as shown in FIG. 2, the terminal device 10 displays the property information provided to the user U01 by using the agent function in the agent function corresponding window W3. In the agent function corresponding window W3 shown in FIG. 2, a plurality of property information is displayed in association with a plurality of evaluation axes. Further, in the agent function compatible window W3 shown in FIG. 2, heading information indicating "comprehensive evaluation", which is one of the evaluation axes, heading information indicating "building / room", which is one of the evaluation axes, and evaluation. Heading information indicating "location / environment", which is one of the axes, is displayed.

(1-1-1. Property evaluation score)
Hereinafter, a method for calculating a property evaluation score for evaluating a property for each of a plurality of evaluation axes will be described. FIG. 3 is a diagram showing an outline of a method for calculating a property evaluation score according to an embodiment. FIG. 3 illustrates a method of calculating a score for a 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 for each property from a plurality of service users through an 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 viewpoint included in the collected review information as a plurality of evaluation axes as an evaluation index of the property. For example, as shown in FIG. 3, the information processing apparatus 100 can use the "building / room" and "location / environment" included in the review information as the evaluation axis. Further, the information processing apparatus 100 may use information derived from the viewpoint included in the review information as an evaluation axis.

Further, the information processing apparatus 100 aggregates review information for each evaluation axis, and calculates a property evaluation score for evaluating each property that matches the search conditions for each of the plurality of evaluation axes based on the plurality of evaluation elements. do. Evaluation factors include points, number of comment posts, number of comment characters, number of positive words, user attributes, posting freshness, and number of users. The evaluation element may include elements other than those shown in FIG. In this way, the information processing apparatus 100 can calculate an unbiased and complex 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 comments posted corresponds to the information on the number of comments posted by the service user for each viewpoint on the target property. The number of comment characters corresponds to the information on the number of characters of comments posted for each viewpoint for the target property. The number of positive words corresponds to the number of positive expressions included in the comments posted to the service user for each viewpoint. The user attribute corresponds to the information related to the attribute of the user who posted the review information. Posting freshness corresponds to the time stamp (date and time information) when the review information was posted. The number of users corresponds to the number of users for each viewpoint that posted a review.

Among the above-mentioned evaluation elements, the number of comment characters, the number of positive words, the user attributes, and the freshness of posting are coefficiented as weighting elements for weighting the score.

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

Regarding the number of positive words, when the number of positive expressions included in the comment is 5, the coefficient information preset in association with the number of positive expressions, such as coefficient 1.3, is used. It can be made into a coefficient by substituting.

The coefficient information associated with the number of positive words in advance may be changed according to the user. For example, the information processing apparatus 100 labels the property information provided to the service user in advance via the agent function compatible window W3. As the label given to the property information, for example, a positive expression for the property can be arbitrarily extracted from the review information. Examples of labels include "good manners of residents", "equipment enhancement", and "well-managed and well-cleaned". The information processing apparatus 100 receives an evaluation from a service user for a property for each property information via the agent function compatible window W3. Further, the information processing apparatus 100 records the evaluation of the property information for each service user in association with the label attached to the property information. Then, when the information processing apparatus 100 calculates the above-mentioned property evaluation score for each evaluation axis, the information processing apparatus 100 specifies the number of positive words based on the positive words corresponding to the service users. 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 in the review contributor (for example, the user ID: "U001" or "U002" user shown in FIG. 3), the coefficient It can be made into a coefficient by substituting it with the coefficient information set in advance in association with the information related to the user attribute, such as 1.5.

In addition, regarding the freshness of posting, if the posted year is all this year, it is converted into a coefficient by replacing it with the coefficient information preset in association with the time stamp (date and time information) such as coefficient 1.0. can.

The coefficienting method of the evaluation element is not limited to the above-mentioned example, and any method can be used. In addition, the above-mentioned evaluation elements include elements such as points that have an upper limit and the corresponding values fall within a certain range, and elements such as the number of comments that the corresponding values do not fall within a certain range. Contains possible elements. Therefore, the information processing apparatus 100 may standardize the values corresponding to all the evaluation elements by using the Z value or the like so that all the evaluation elements can be scored on the same scale.

Further, the information processing apparatus 100 calculates the score by an evaluation logic different for each evaluation axis. For example, the evaluation logic can be changed by changing the coefficient information associated with the evaluation element described above for each evaluation axis. As a result, the information processing apparatus 100 can calculate an appropriate score for the transaction target 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, "Condominium EX1", the property evaluation score corresponding to the comprehensive evaluation, the property evaluation score corresponding to the "building / room", and the "location / environment" are supported. The property evaluation score etc. are shown. The comprehensive evaluation corresponds to the total value of the scores corresponding to each evaluation axis. In this way, the information processing apparatus 100 scores all the 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 value from a plurality of properties that match the search conditions. As a result, the information processing apparatus 100 can select useful information for the service user.

(1-1-2. How to post property information)
Hereinafter, the display method of the property information selected based on the property evaluation score will be described. The information processing apparatus 100 calculates a score for each evaluation axis, and then selects a property for each of a plurality of evaluation axes from a plurality of properties that match the search conditions based on the calculated score. Then, the information processing device 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 heading information indicating the plurality of evaluation axes and posted. As a result, the information processing apparatus 100 can provide the service user with information regarding the transaction target in an easy-to-understand manner.

When posting the property information with respect to the list information, the information processing apparatus 100 may rearrange the display position of the heading information indicating the evaluation axis based on the user context of the user U01 who is the provider. For example, the information processing apparatus 100 can estimate the search conditions that the provider user U01 places importance on in the property search based on the search history when the property is searched using the information providing service. For example, it can be estimated that the more frequently used as a search condition, the more important the search condition is. In addition, for example, an index corresponding to a sorting method having a large number of selections of the sorting method selected when sorting the display order of search results (for example, "highest evaluation order" or "newest publication date"", etc. ), It can be estimated that the condition is more important.

Then, in the information processing apparatus 100, for example, when the agent function compatible window W3 supports upward scrolling, the evaluation axis corresponding to the important search condition moves toward the agent function compatible window W3 and other evaluation axes. Change the display position of the heading information from the default position so that it is displayed relatively at the top. For example, in the example shown in FIG. 2, in the agent function corresponding window W3 displayed on the terminal device 10, the heading information indicating "comprehensive evaluation", which is one of the evaluation axes, is displayed at the top. Further, in the example shown in FIG. 2, the heading information indicating "building / room", which is one of the evaluation axes, is displayed under the heading information of "comprehensive evaluation". Further, in the example shown in FIG. 2, it is shown that the heading information of "location / environment", which is one of the evaluation axes, is displayed under the heading information of "building / room". When it is difficult to specify the context of the user U01 due to a shortage of data samples or the like, the information processing apparatus 100 can determine the display position of the heading position indicating the evaluation axis to a predetermined predetermined position. In this way, the information processing apparatus 100 can provide property information according to the search tendency, hobbies, and tastes of service users.

Further, the information processing apparatus 100 provides heading information indicating an evaluation axis in which the difference between the highest score and the lowest score of the property evaluation score calculated for each evaluation axis is equal to or greater than a predetermined threshold value among the plurality of evaluation axes. You may post it with priority. As a result, the information processing apparatus 100 can present the user with an evaluation axis having a disparity between the property information as much as possible.

Further, when the information processing apparatus 100 posts the property information of the selected property in association with each of the heading information indicating the plurality of evaluation axes, 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 position of the property information to be displayed may be rearranged. For example, when the information processing device 100 is configured to be viewable by moving the property information posted in the list information to the left (when it supports left scrolling), the property information of the property having a higher property evaluation score is higher. The display position is changed so that it is displayed on the left side of the property information of other properties toward the agent function compatible window W3. The information processing device 100 can arbitrarily determine the display position of the property information according to the scroll direction when browsing the property information. As a result, the information processing apparatus 100 can present, for example, property information that is presumed to be useful to the service user in order.

(1-2. Property selection based on rent trends)
Further, when the information processing apparatus 100 selects a property to be posted in the above-mentioned list information from a plurality of properties that match the search conditions specified by the user U01, the rent associated with each of the plurality of properties ("" Select a property that meets the specified conditions based on the comparison result between the trend of average rent transition calculated from the example of "amount associated with each transaction target") and the trend of rent transition for each property. May be good. As described above, the information processing apparatus 100 can provide useful information to the service user in evaluating the property information by selecting the property information according to the tendency of the change in the amount of money. In addition, the tendency of the average rent calculated from the rent associated with each of the above-mentioned multiple properties is the aggregation and processing of the rent associated with each of the multiple properties that match the search conditions specified by the service user. This is an example of statistical information about the entire multiple properties obtained. In addition, the above-mentioned tendency of rent transition for each property is an example of statistical information for each property obtained by individually totaling and processing rents associated with properties that match the search conditions.

Hereinafter, an example of a property selection method based on the tendency of rent transition will be described with reference to FIG. FIG. 4 is a diagram showing an example of rent transition according to the embodiment. In FIG. 4, the transition of the past average rent of a plurality of properties in the target area (area) designated 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. Has been done.

The information processing device 100 is financially beneficial to service users based on the result of comparison between the rate of increase in average rent over the most recent fixed period and the rate of increase in rent for each property to be scored over the most recent fixed period. You can select various properties. More specifically, the information processing apparatus 100 calculates the rate of increase in the average rent in the target area based on the average rent from 2015 to 2021 with reference to the example shown in FIG. Further, as shown in FIG. 4, the information processing apparatus 100 calculates the rate of increase in the rent of the target property based on the rent from 2015 to 2021.

Next, the information processing apparatus 100 compares, for example, the rate of increase in the average rent in the target area shown in FIG. 4 with the rate of increase in the rent of the target property shown in FIG. As a result of comparison, when the rate of increase in rent of the target property shown in FIG. 4 is lower than the rate of increase in average rent in the target area shown in FIG. 4, the information processing apparatus 100 uses the target property shown in FIG. 4 as a service user. Select as a property that is financially beneficial to you. That is, the information processing apparatus 100 selects the target property shown in FIG. 4 as a property with a low rent. As a result, the information processing apparatus 100 can individually select property information having an advantage in terms of money from a plurality of transaction targets that match the search conditions, using the rate of increase in the amount of money as a measure.

Alternatively, the information processing apparatus 100 has a rate of decrease in average rent for a plurality of properties that match the search conditions specified by the user U01 in the latest fixed period, and a rate of decrease in rent for each property to be scored in the latest fixed period. Based on the comparison result with, it is possible to select a property that is financially beneficial to the service user.

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

Next, the information processing apparatus 100 compares, for example, the rate of decrease in average rent in the target area shown in FIG. 4 with the rate of decrease in rent of the target property shown in FIG. As a result of comparison, when the rate of decrease in rent of the target property shown in FIG. 4 is larger than the rate of decrease in average rent in the target area shown in FIG. 4, the information processing apparatus 100 uses the target property shown in FIG. 4 as a service user. Select as a property that is financially beneficial to you. That is, the information processing apparatus 100 selects the target property shown in FIG. 4 as a property with a low rent. As a result, the information processing apparatus 100 can individually select a transaction target having a monetary advantage from a plurality of transaction targets that match the search conditions, using the rate of decrease in the amount as a measure. In addition, when the information processing apparatus 100 selects a property using the above-mentioned decline rate as an evaluation index of a property that is financially beneficial to the service user, the condition is that the decline rate is equal to or higher than a predetermined threshold value. good.

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

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

In the example shown in FIG. 5, instead of the heading information indicating "comprehensive evaluation", the heading information indicating that the service user is financially beneficial (for example, "property that is advantageous from the viewpoint of rent transition") is used. The point displayed on the terminal device 10 is different from the example shown in FIG. Similar to the method of posting property information described above, the information processing apparatus 100 displays heading information indicating an evaluation axis based on the user context of user U01, which is a provider, when posting property information for list information. You may rearrange the positions.

Further, when the information processing apparatus 100 posts the property information of the selected property in association with the heading information indicating that it is financially beneficial to the service user, the amount of monetary profit for the service user is increased or decreased. Based on this, the display position of the property information to be displayed in association with the heading information may be rearranged. For example, when the information processing device 100 is configured to be viewable by moving the property information posted in the list information to the left (when it supports left scrolling), the property has a large monetary profit for the service user. The more the property information is, the more the display position is changed so that it is displayed on the left side of the property information of other properties toward the agent function compatible window W3. The information processing device 100 can arbitrarily determine the display position of the property information according to the scroll direction when browsing the property information.

As described above, the information processing apparatus 100 according to the embodiment can provide useful information to the user in evaluating the property to be traded.
