[1. Example of information provision processing]
First, with reference to FIG. 1, an information providing method performed by an information providing apparatus according to an embodiment will be described. FIG. 1 is a diagram for explaining an information providing method performed by an information providing apparatus according to an embodiment.

The information providing device 1 provides electronic commerce (EC) services. For example, the information providing device 1 executes information providing processing regarding a transaction object or transaction processing for a transaction object. Here, the transaction object is a product or a service. Note that the transaction objects traded in the electronic commerce service include the transaction objects traded in various modes such as an electronic shopping mall (online mall), an online shopping site, an auction site, and a flea market site.

The information providing device 1 stores transaction object information, which is information about the transaction object, and user information, which is information about the user U of the terminal device 2. The transaction object information includes various information regarding the transaction object. For example, the transaction object information includes various information used to provide information about the transaction object.

The transaction object information includes various information such as, for example, a sales source, a sales price, an image of a transaction object, a category, a title, a description, a payment method, a sales period, and the number of items sold. Further, the transaction object information includes, for example, information such as the sales history, browsing history, and user review history of the transaction object. In addition, transaction target information includes, for example, the number of reservations, orders, sales, order amount (sales), sales start date and time, number of views of information indicating the transaction target (number of PV (Page View)), transaction Contains information such as user reviews for the target.

Further, the user information includes, for example, user U's attribute information, behavior history in electronic commerce services, and the like. The attribute information includes various information such as information indicating demographic attributes such as age, gender, area of residence, and occupation, and information indicating psychographic attributes such as interests and lifestyle. The behavior history includes, for example, a viewing history of transaction target information in an electronic commerce service, a purchase history of transaction targets, and the like.

The information providing device 1 receives user reviews posted from each user U regarding the transaction object purchased by each user U (step S1). For example, the user U operates the terminal device 2 to enter review information regarding the evaluation of the transaction object purchased by the user U into the user review posting screen provided by the information providing device 1, and to set the information on the user review posting screen. button, etc. that appears. As a result, the user review information input by the user U is transmitted from the terminal device 2 to the information providing device 1.

The user review posting screen includes, for example, an overall evaluation value input area for inputting an overall evaluation value, a comment input area for inputting user U's comments, an item-specific evaluation selection area for inputting an item-specific evaluation, etc. It is included.

In the comprehensive evaluation value input area, for example, the comprehensive evaluation value of the transaction object by the user U is set. The overall evaluation score is, for example, a maximum of 5 points, and can be set up to the first decimal place. The comment input area includes an input frame for inputting user U's comment.

When the transaction object is shampoo, the items shown in the item-based evaluation selection area include, for example, comfort of use, hair finish, lathering, creaminess, moisturizing properties, and fragrance. In this case, the item-specific evaluation of the item "comfort" is selected by the user U from, for example, five options: very bad, bad, average, good, and very good. Further, the item-specific evaluation of the item "hair finish" is selected by the user U from among five options: moist, slightly moist, normal, slightly refreshing, and refreshing.

Further, the item-specific evaluation of the item "foaming" is selected by the user U from, for example, five options: very bad, bad, average, good, and very good. Further, the item-specific evaluation of the item "creaminess" is selected by the user U from, for example, five options: not very much, not at all, normal, yes, and very much.

Further, the item-specific evaluation of the item "moisturizing property" is selected by the user U from, for example, five options: very bad, bad, average, good, and very good. Further, the item-specific evaluation of the item "fragrance" is selected by the user U from, for example, five options: not very much, not at all, normal, yes, and very much.

The information providing device 1 calculates the evaluation value of each transaction target based on the user review submissions received from each user U (step S2). In the process of step S2, the information providing device 1 calculates the overall evaluation value, the evaluation value for each item, etc. of each transaction object. The comprehensive evaluation value is, for example, the average value of comprehensive evaluation values included in user reviews for the same transaction object. Each item-specific evaluation value is, for example, an average value of corresponding item-specific evaluation values among a plurality of item-specific evaluation values included in user reviews for the same transaction object.

For example, if the transaction object is shampoo and the item is "comfort," the evaluation value for each item is 1 point if "very bad" is selected, 2 points if "poor" is selected, If "fair" is selected, the score is 3 points, if "good" is selected, the score is 4 points, and if "very good" is selected, the score is 5 points. Then, three users U post user reviews for the transaction object, and the three users U's evaluation values for the item "comfort" are 4 points, 4 points, and 5 points. . In this case, the information providing device 1 sets the item-specific evaluation value of the item "comfort of use" for the transaction object to 4.33 points (=(4 points + 4 points + 5 points)/3).

If the transaction object is shampoo, there are multiple evaluation axes, such as an evaluation axis for the item ``comfort'', an evaluation axis for the item ``hair finish'', an evaluation axis for the item ``foaming'', and an evaluation axis for the item ``creaminess''. A plurality of evaluation axes including the evaluation axis are set. Note that the evaluation axis for the item "hair finish" may be divided into two evaluation axes: an evaluation axis for the item "refreshing" and an evaluation axis for the item "moist." The information providing device 1 specifies the position of each transaction object with respect to each of the plurality of evaluation axes by calculating the evaluation value for each item of each transaction object.

Note that the information providing device 1 may calculate the evaluation value for each item from the user U's comment input in the comment input area when the item evaluation is not set for the user U in the item evaluation input area. can. For example, the information providing device 1 morphologically analyzes the user U's comment, extracts information indicating the user U's evaluation of the item, and calculates an item-specific evaluation value from the extracted information indicating the evaluation.

After that, the information providing device 1 receives an information providing request from the terminal device 2 of the user U (step S3). For example, an information request may include a search query that includes a search keyword, a query that includes a URL (Uniform Resource Locator) that specifies a specific category or transaction target, or a request for content that is the top page of a site such as a shopping site. Requests that include a URL, but are not limited to these examples.

When the information providing device 1 receives the information providing request from the terminal device 2, the information providing device 1 selects a plurality of evaluation axes to be included in the content provided to the user U based on the user information of the user U (step S4). For example, the information providing device 1 selects a plurality of evaluation axes as evaluation axes to be included in the content based on the user information of the user U from among the plurality of evaluation axes set for the transaction target group in response to the information provision request. .

When the transaction target category specified by the search keyword included in the search query is shampoo, the target category is shampoo, and the information providing device 1 selects the content from among the multiple evaluation axes set for the shampoo group. Select multiple evaluation dimensions to include. In the following, the category to be traded may be referred to as a target category, and the user U of the terminal device 2 who has transmitted the information provision request may be referred to as a content provision target user.

The information providing device 1 selects a plurality of evaluation axes to be included in the content from among the plurality of evaluation axes set for the transaction object group of the target category based on the user information of the content provision target user.

For example, assume that the transaction target group of the target category is the shampoo group. In this case, the information providing device 1 has an evaluation axis for the item "comfort", an evaluation axis for the item "hair finish", an evaluation axis for the item "foaming", an evaluation axis for the item "creaminess", and an evaluation axis for the item "moisturizing property". Select a plurality of evaluation axes to be included in the content from among the evaluation axis of the item "fragrance" and the evaluation axis of the item "fragrance".

For example, the information providing device 1 selects, from among these evaluation axes, a plurality of evaluation axes that are estimated to have a high level of interest of the content provision target user based on the user information of the content provision target user.

Here, the level of interest of the users to whom content is provided is ranked in the order of "hair finish", "foaming", "creaminess", "comfort", "fragrance", and "moisturizing". Suppose it becomes lower. In this case, the information providing device 1 selects, for example, the top three evaluation axes, that is, the evaluation axis for the item "hair finish", the evaluation axis for the item "foaming", and the evaluation axis for the item "creaminess". . In addition, when the evaluation axis of the item "hair finish" is divided into two, the information providing device 1 can divide the evaluation axis into two, for example, the top four evaluation axes, that is, the evaluation axis of the item "refreshing", the evaluation axis of the item "moist", Select the evaluation axis for the item "foaming" and the evaluation axis for the item "creaminess."

The level of interest of the user to whom the content is provided can be determined by, for example, the attribute information of the user to whom the content is provided, the purchase history of the transaction object by the user to whom the content is to be provided, the viewing history of the transaction object by the user to whom the content is to be provided, and an itemized evaluation based on user reviews. Estimated by the information providing device 1 based on at least one of the values. The item-by-item evaluation value based on the user review is, for example, the item-by-item evaluation value based on the user review of the content provision target user or the past user review by another user U whose attributes are similar to the content provision target user.

Further, the information providing device 1 can also select at least one evaluation axis among the plurality of evaluation axes as the evaluation axis to be included in the content based on the distribution of the evaluation values for each item. For example, the information providing device 1 may prioritize an evaluation axis with a wide distribution range of item-specific evaluation values and select it as an evaluation axis to be included in the content, or prioritize an evaluation axis with a high degree of dispersion of item-specific evaluation values and include it in the content. It can be selected as an evaluation axis.

Next, the information providing device 1 selects a plurality of transaction objects to be placed in the evaluation axis area, which is an area indicated by the plurality of evaluation axes selected in step S4 (step S5). For example, the information providing device 1 selects each of the plurality of transaction objects with a high ranking among the plurality of transaction objects included in the target category as a selected transaction object candidate that is a candidate for the selected transaction object. Then, the information providing device 1 selects a plurality of selected transaction object candidates that can be distributed and arranged in the evaluation axis area from among the selected plurality of selection transaction object candidates as a plurality of selected transaction object candidates.

Further, the information providing device 1 selects one or more transaction objects that the content provision target user has purchased in the past from among the plurality of transaction targets included in the target category, based on the user information of the content provision target user. .

Further, the information providing device 1 selects a reference transaction object that is a reference transaction object. The reference transaction object is, for example, a transaction object placed at the center of the evaluation axis area or a transaction object highlighted in the evaluation axis area as a reference transaction object. The information providing device 1 selects the transaction target as a reference transaction target based on, for example, the purchase history of the transaction target by the content provision target user, the viewing history of the transaction target by the content provision target user, or the user review history of the content provision target user. can do. The standard transaction object is one of the selected transaction objects.

Next, the information providing device 1 generates content to be provided to the content provision target user based on the plurality of evaluation axes selected in step S4 and the plurality of transaction objects selected in step S5 (step S6).

In the content generated in step S6, information on each of the plurality of transaction objects is arranged at a position within the evaluation axis area where the plurality of evaluation axes are shown and according to the evaluation value based on the user review. In this content, information on each of a plurality of transaction objects is arranged based on the reference transaction object selected in step S6.

The information providing device 1 provides the content generated in step S6 to the terminal device 2 (step S7). The terminal device 2 displays content provided from the information providing device 1. As a result, the user to whom the content is provided will be able to view the information on each evaluation axis of each transaction object from the content where the information of multiple transaction objects is arranged in the area corresponding to the evaluation value based on user reviews in the area where multiple evaluation axes are shown. The location can be easily determined. Therefore, it is possible to improve convenience when a content provision target user selects a transaction target from among a plurality of transaction targets.

The content shown in FIG. 1 includes an evaluation axis for the item "hair finish," an evaluation axis for the item "foaming," and an evaluation axis for the item "creaminess." The end of the evaluation axis for the item "foaming" and the end of the item "creaminess" are connected to the middle position of the evaluation axis for the item "hair finish". In addition, if the evaluation axis for the item "Hair finish" is divided into two, the evaluation axis for the item "Refreshing" and the evaluation axis for the item "Moist", in the evaluation axis area, the evaluation axis for the item "Refreshing" and the evaluation axis for the item The ends of the evaluation axis for the item "moistness", the evaluation axis for the item "foaming", and the evaluation axis for the item "creaminess" are connected.

Further, a plurality of evaluation axes forming an evaluation axis area included in the content are selected based on user information of the user to whom the content is provided. Therefore, content including a plurality of evaluation axes suitable for the user to whom the content is provided can be provided to the user to whom the content is to be provided. Thereby, it is possible to improve convenience when a content provision target user selects a transaction target from among a plurality of transaction targets.

The information on the transaction object included in the content includes, for example, information indicating the name and identification code of the transaction object, image information on the transaction object, information indicating the price of the transaction object, information indicating the evaluation by the user U of the transaction object, and It includes at least some information such as information regarding the characteristics of the transaction object. If the transaction object is a product, the identification code is the model number of the product. The information indicating the evaluation by the user U of the transaction object is, for example, the average value of the overall evaluation value of the transaction object, and may include the average value of the item-specific evaluation values of the transaction object.

The information providing device 1 can receive an operation to enlarge the evaluation axis area by a content providing target user. When the information providing device 1 receives an operation to enlarge the evaluation axis area by the content provision target user, the information providing device 1 reselects a plurality of transaction targets in accordance with the enlargement operation. The information providing device 1 causes the terminal device 2 to display information on a plurality of transaction targets reselected in response to the enlargement operation. Thereby, the information providing device 1 can provide the content provision user with information on a plurality of transaction objects according to the enlargement operation, and when the content provision user selects a transaction object from among the plurality of transaction objects. can improve the convenience of

Furthermore, the information providing device 1 may re-select a larger number of transaction objects than the number of transaction objects whose information was included in the content provided in step S7 as the plurality of transaction objects according to the enlargement operation. can. For example, the information providing device 1 can select more transaction objects as a plurality of transaction objects according to the enlargement operation as the enlarged display area becomes larger. As a result, content provision users can learn more information about transaction targets through the enlargement operation, which improves convenience when content provision users select transaction targets from among multiple transaction targets. I can do it.

You can choose one option.

The itemized evaluation selection area 551e is an area for inputting the itemized evaluation of the item "moisturizing property." In the item-specific evaluation selection area 551e, five options are shown as the item-specific evaluation for the item "foaming": very bad, bad, average, good, and very good, and the user U selects one from these five options. You can choose one option.

The item-specific evaluation selection area 551f is an area for inputting the item-specific evaluation of the item "fragrance." In the item-specific evaluation selection area 551f, five options are shown as the item-specific evaluation for the item "foaming": not at all, not at all, normal, yes, and very much, and the user U selects one from these five options. You can choose one option.

User U operates the terminal device 2, inputs the overall evaluation value in the overall evaluation value input area 52, inputs a comment and title in the comment input area 53 and title input area 54, and enters the item-based evaluation selection areas 551a to 551f. After selecting an option for each item, press the send button 56.

As a result, the user review information including the overall evaluation value, comment, title, and information on the options for each item input by the user U is transmitted from the terminal device 2 to the information providing device 1, and the user review for the transaction object is posted. will be held. User review information transmitted from the terminal device 2 is accepted by the reception unit 31 . The reception unit 31 causes the transaction target information storage unit 21 to store user review information that is user review information transmitted from the terminal device 2 .

Note that in the above example, there are five options for each item, and the evaluation is in five stages, but the number of options may be four or less, or six or more. That is, the evaluation of each item may be an evaluation of four stages or less, or may be an evaluation of six stages or more. Further, in the above example, the overall evaluation value is a perfect score of 5 points, but it may be a perfect score of 10 points, or a perfect score of 100 points. In the following, when each of the item-based evaluation selection areas 551a to 551f is shown without being individually distinguished, they may be referred to as item-based evaluation selection area 551.

The reception unit 31 also receives an operation by the user U to enlarge the evaluation axis area. The operation for enlarging the evaluation axis area by the user U is, for example, an operation for expanding the evaluation axis area around a portion of the evaluation axis area that corresponds to the operation by the user U.

For example, when the operation section of the terminal device 2 is a mouse, the point corresponding to the operation of the user U is a point specified by the user U's click operation, and when the operation section of the terminal device 2 is a touch panel, the point specified by the user U's operation is a point specified by the user U's click operation. This is the position between two fingers by the U pinch-out operation.

In addition, the enlargement rate of the evaluation axis area by the enlargement operation is, for example, the amount of rotation of a wheel by the user U when the operating section of the terminal device 2 is a mouse, and when the operating section of the terminal device 2 is a touch panel, the This is the amount of change in the distance between two fingers due to the pinch-out operation of U.

Further, the reception unit 31 receives selection by the user U of a category to be traded. For example, the reception unit 31 provides the terminal device 2 with content showing a category list, which is a list of categories to be traded. The terminal device 2 displays the content indicating the category list provided by the reception unit 31, and when a category is selected by user U's operation from among the plurality of categories included in the category list, information on the selected category is displayed. is transmitted to the information providing device 1. The information providing device 1 receives category information from the terminal device 2 to receive selection of a category to be traded by the user U.

[3.3.3. Specification part 32]
The specifying unit 32 specifies the position of each of the plurality of transaction objects with respect to each of the plurality of evaluation axes based on user reviews for each of the plurality of transaction objects. For each transaction object, evaluation axes for each item described above are set.

The specifying unit 32 performs, for each transaction object, a process of calculating an evaluation value for each item based on user review information for the same transaction object stored in the transaction object information storage section 21, for example. The specifying unit 32 then specifies a position corresponding to the calculated item-specific evaluation value as a position corresponding to the evaluation axis. For example, when the itemized evaluation value is "3", the identifying unit 32 identifies the position where the evaluation value is "3" on the evaluation axis as the position of the transaction target.

The item-specific evaluation value of each transaction object is the average value of the item-specific evaluation values included in the user review information for the same transaction object, and may be referred to as the item-specific overall evaluation value below. The specifying unit 32 calculates an item-specific overall evaluation value for each transaction object and each item. Note that the specifying unit 32 determines the weight of the itemized evaluation value included in the user review information posted by the specific user U from the weight of the itemized evaluation value included in the user review information posted by other users U. It is also possible to calculate the average value of the evaluation values for each item by increasing the value.

Further, when the item-specific evaluation is not set for user U in the item-specific evaluation selection area 551, the specifying unit 32 calculates each item-specific evaluation value from the user U's comment input in the comment input area 53. You can also do it. For example, the specifying unit 32 morphologically analyzes the user U's comment, extracts information indicating the user U's evaluation of the item, and calculates an item-specific evaluation value from the extracted information indicating the evaluation.

In addition, the specifying unit 32 determines whether each transaction object It is also possible to calculate an item-specific overall evaluation value for each item. For example, the identifying unit 32 performs a transaction by weighting and adding the item-specific evaluation value input in the item-specific evaluation selection area 551 and the item-specific evaluation value calculated from the user U's comment input in the comment input area 53. It is also possible to calculate an item-specific overall evaluation value for each object and each item.

Furthermore, for transaction objects for which the item-specific evaluation selection area 551 is not set on the user review posting screen 50, the specifying unit 32 similarly determines each item-specific evaluation value from the user U's comments input in the comment input area 53. can be calculated.

Further, the specifying unit 32 can also determine, for each item, an individual evaluation value for each item, which is an evaluation value for each item based on past user reviews by other users U whose attributes are similar to the content provision target user. The individual item evaluation value is, for example, an item evaluation value for each item included in a past user review by another user U whose attributes are similar to the content provision target user.

The specifying unit 32 can also specify a position according to the individual evaluation value for each item as a position corresponding to the evaluation axis. For example, when the individual evaluation value for each item is 3, the identifying unit 32 identifies the position where the evaluation value is 3 on the evaluation axis as the position of the transaction target.

Note that the method of specifying the position of the transaction object on the evaluation axis by the specifying unit 32 is not limited to the example described above, and the specifying unit 32 can specify the position of the transaction object on the evaluation axis by various methods.

Further, the specifying unit 32 calculates a comprehensive evaluation value of each transaction target based on the user review information stored in the transaction target information storage unit 21. The comprehensive evaluation value is, for example, the average value of comprehensive evaluation values included in user reviews for the same transaction object.

[3.3.4. Selection section 33]
The selection unit 33 selects a plurality of evaluation axes and a plurality of transaction targets to be included in the content provided to the user U when the information provision request is accepted by the reception unit 31. For example, the selection unit 33 selects a category of transaction objects to be included in the content, and selects two or more evaluation axes based on user information from among a plurality of evaluation axes set for a group of transaction objects of the selected category. Further, the selection unit 33 selects a plurality of transaction objects to be included in the content from among the group of transaction objects in the selected category. Each selection method by the selection unit 33 will be explained below.

[3.3.4.1. Selection of categories of transactions to include in content]
The selection unit 33 selects a transaction target category to be included in the content to be provided to the content provision target user based on the information included in the information provision request received by the reception unit 31 and the user information of the content provision target user. Select a target category.

For example, when a transaction target category is specified in the information provision request received by the reception unit 31, the selection unit 33 selects the category specified in the information provision request as the target category. For example, if the transaction target category specified by the search keyword included in the search query is shampoo, the selection unit 33 selects shampoo as the target category.

Further, if the category to be traded is not specified in the information provision request received by the reception unit 31, the selection unit 33 selects the target category based on the user information of the content provision target user. For example, the selection unit 33 selects a category in which the content provision target user is interested as the target category, based on the user information of the content provision target user. The categories in which the content provision target user is interested are specified, for example, from the content provision target user's attribute information, purchase history, browsing history, and the like.

In addition, if there is a category that further subdivides the category of the transaction target group specified in the information provision request received by the reception unit 31, the selection unit 33 makes the information provision request based on the user information of the content provision target user. Narrowing down processing can be performed to select the category of the transaction object group to be included in the content from among the plurality of categories included in the category specified by .

Note that the method for selecting the category of the transaction object group to be included in the content is not limited to the above-mentioned example. For example, even if a transaction target category is specified in the information provision request, the selection unit 33 can select the target category based on the user information of the content provision target user. Further, the selection unit 33 can also select, for example, a randomly selected category as the target category, regardless of whether the transaction target category is specified in the information provision request. In the following, the category selected as the target category by the selection unit 33 may be referred to as the target category.

[3.3.4.2. Selection of evaluation axes to include in content]
The selection unit 33 selects an evaluation axis to be included in the content from among a plurality of evaluation axes set in the transaction target group of the target category. For example, when the target category is shampoo, the selection unit 33 selects an evaluation axis for the item "comfort", an evaluation axis for the item "hair finish", an evaluation axis for the item "foaming", and an evaluation axis for the item "creaminess". , a plurality of evaluation axes to be included in the content are selected from among the evaluation axis of the item "moisturizing property" and the evaluation axis of the item "fragrance".

For example, when the number of evaluation axes set for the transaction object group of the target category exceeds the number that can be arranged in the content, the selection unit 33 performs evaluation axes narrowing down processing and selects a plurality of evaluation axes to be included in the content. Even if the number of evaluation axes set for the transaction object group of the target category does not exceed the number that can be arranged in the content, the selection unit 33 performs evaluation axes narrowing processing to select multiple evaluation axes to be included in the content. You can choose. Note that the number of evaluation axes that can be arranged in the content is four, but it may be five or more, or three or less.

For example, the selection unit 33 performs a narrowing process to select a plurality of evaluation axes to be included in the content from among a plurality of evaluation axes set in the transaction target group of the target category, based on user information that is information of the content provision target user. I do.

For example, the selection unit 33 calculates the interest score of the content provision target user for each of the plurality of evaluation axes set for the transaction target group of the target category, and selects the plurality of content provision target users based on the calculated interest score. You can select the evaluation axis. The interest score is calculated, for example, based on the user information of the content provision target user. The interest score of the content provision target user is calculated such that, for example, the transaction target that the content provision target user frequently views is higher, and the transaction target that the content provision target user purchases more times is higher.

The selection unit 33 can select a plurality of evaluation axes to be included in the content, for example, by selecting a predetermined number of evaluation axes in descending order of interest score. Further, the selection unit 33 can also select a plurality of evaluation axes to be included in the content by selecting an evaluation axis with an interest score equal to or higher than a predetermined value.

Further, the selection unit 33 selects a plurality of evaluation axes set for the transaction target group of the target category based on, for example, the attributes of the content provision target user or the purchase history of the transaction target by user U, and user review information. It is also possible to select at least one evaluation axis from among them.

For example, the selection unit 33 uses the item-based evaluation value based on past user reviews by other users U whose attributes are similar to the content provision target user as the evaluation value for determination, and selects the items set in the transaction target group of the target category. Narrowing down processing can be performed to select at least one evaluation axis from a plurality of evaluation axes. The selection unit 33 can perform, for example, a narrowing process that prioritizes and selects evaluation axes with high item-specific evaluation values based on past user reviews by other users U whose attributes are similar to the content provision target user.

In addition, the selection unit 33 uses, as determination evaluation values, item-specific evaluation values based on user reviews of transaction objects purchased in the past by other users U whose attributes are similar to the content provision target user, and selects the transaction object of the target category. Narrowing down processing can be performed to select at least one evaluation axis from a plurality of evaluation axes set in a group. The selection unit 33 performs, for example, a narrowing process that prioritizes and selects evaluation axes with high item-specific evaluation values based on user reviews of transaction objects purchased in the past by other users U whose attributes are similar to the content provision target user. be able to.

In addition, the selection unit 33 selects a plurality of evaluation axes set for the transaction object group of the target category, using the item-by-item evaluation value based on the user review of the transaction object purchased in the past by the content provision target user as the evaluation value for judgment. Narrowing down processing can be performed to select at least one evaluation axis from among the following. For example, the selection unit 33 can perform a narrowing process of preferentially selecting evaluation axes with high item-specific evaluation values based on user reviews of transaction objects purchased by the content provision target user in the past.

In addition, the selection unit 33 selects at least one evaluation axis from among the plurality of evaluation axes set for the group of transaction objects in the target category, using the item-specific evaluation value based on the user review for the transaction object in the target category as the evaluation value for judgment. Narrowing down processing can be performed to select evaluation axes. For example, the selection unit 33 can perform a narrowing process of preferentially selecting evaluation axes with high item-specific evaluation values based on user reviews for transaction objects in a specific category.

In addition, the selection unit 33 uses the average value of the evaluation values for each item as the evaluation value for judgment, and selects an evaluation axis with a higher evaluation value for judgment from among the plurality of evaluation axes set for the transaction target group of the target category. It is also possible to perform narrowing down processing.

Further, the selection unit 33 can select at least one evaluation axis from among the plurality of evaluation axes set for the transaction object group of the target category, based on the distribution of the evaluation values for each item. For example, the selection unit 33 can preferentially select an evaluation axis with a wide distribution range of item-specific evaluation values among a plurality of evaluation axes set for the target category. Further, the selection unit 33 can perform a narrowing process of preferentially selecting an evaluation axis with a high degree of dispersion of item-specific evaluation values from among a plurality of evaluation axes set for the transaction target group of the target category.

Further, the selection unit 33 can select a plurality of evaluation axes including two evaluation axes whose evaluation criteria have a predetermined relationship with each other. The predetermined relationship is a relationship in which the evaluation criteria are reciprocal or a relationship in which the evaluation criteria are related. For example, when the transaction object group of the target category is shampoo, the evaluation axis of the item "foaming" and the evaluation axis of the item "creamy" are in a relationship in which their evaluation criteria are related. Note that a relationship in which the evaluation criteria are reciprocal is not limited to a relationship in which the evaluation criteria are reciprocal, but includes a relationship in which the degree of reciprocity between the evaluation criteria is greater than or equal to a predetermined value. The selection unit 33 divides the evaluation axis of the item "hair finish" into two, an evaluation axis of the item "refreshing" and an evaluation axis of the item "moist", and divides the evaluation axis of the item "hair finish" into two, and the two have a predetermined relationship with each other's evaluation criteria. It can also be selected as one evaluation axis. The evaluation axis for the item "moist" and the evaluation axis for the item "refreshing" have a reciprocal relationship in their evaluation criteria.

For example, when there are three or more sets of two evaluation axes whose evaluation criteria have a predetermined relationship with each other, the selection unit 33 can select the two evaluation axes having higher evaluation values preferentially. In the following, an evaluation axis selected from a plurality of evaluation axes set for a target category may be referred to as a target evaluation axis.

For example, the selection unit 33 selects two evaluation axes in which the vectors of terms corresponding to the evaluation axes are in opposite directions to each other as evaluation axes whose evaluation criteria are in a reciprocal relationship, and Two evaluation axes whose vectors are similar can be selected as evaluation axes whose evaluation criteria are related to each other.

The selection unit 33 generates a vector of terms corresponding to the evaluation axis by natural language processing using, for example, W2V (Word2Vec). For example, the selection unit 33 uses two or more terms that satisfy predetermined conditions as learning data and performs learning so that the vectors of the two or more terms are similar to each other to generate an interest model. Two or more terms that satisfy predetermined conditions are, for example, multiple search keywords included in the same search query, or multiple search queries sent from the terminal device 2 by the same user U within a predetermined time. is a search keyword included in .

The selection unit 33 inputs terms corresponding to the evaluation axes into the generated interest model, and performs a process for each evaluation axis to obtain a vector output from the interest model as a vector of terms corresponding to the evaluation axis. , obtain a vector of terms corresponding to each evaluation axis. For example, if the transaction target is shampoo, terms that correspond to the evaluation axis include "comfort," "hair finish," "foaming," "creaminess," "moisturizing properties," and "fragrance." It is.

The selection unit 33 is configured, for example, by a DSSM (Deep Structured An interest model that outputs a vector (for example, a distributed expression) from information indicating a target such as a search keyword is generated using Semantic Model technology. Note that the method for generating an interest model that outputs a vector from information indicating an object is not limited to the example described above.

Note that two evaluation axes whose evaluation criteria have a predetermined relationship may be set in advance without using vectors of terms corresponding to the evaluation axes.

[3.3.4.3. Selection of transaction objects to include in content]
The selection unit 33 selects a plurality of transaction objects to be placed in an evaluation axis area, which is an area indicated by a plurality of object evaluation axes. In the following, a transaction object selected as a transaction object placed in the evaluation axis area may be referred to as a selected transaction object.

The selection unit 33 selects, for example, each of the plurality of transaction objects that are ranked high among the plurality of transaction objects included in the group of transaction objects in the target category, as selected transaction object candidates that are candidates for the selected transaction object. The selection unit 33 calculates the content by scoring using at least one of information such as the interest level of the user to whom the content is provided, the number of sales per unit period, the comprehensive evaluation value per unit period, and the price. A predetermined number of transaction objects with the highest scores are selected as selected transaction object candidates.

Then, the selection unit 33 can select, as the plurality of selected transaction objects, a plurality of selected transaction object candidates that are distributed and arranged in the evaluation axis region from among the selected plurality of selected transaction object candidates.

For example, the selection unit 33 divides the evaluation axis region into a plurality of regions, and determines a plurality of selected transaction objects such that each of the plurality of divided regions includes at most one selected transaction object. When two or more selected transaction target candidates are included in one divided area, the selection unit 33 selects the selected transaction target candidate with the highest score as the selected transaction target. Note that the selection unit 33 does not determine a selected transaction object in a divided area that does not include even one selected transaction object.

Further, the selection unit 33 selects the selected transaction object candidates in descending order of the score, and if the selected transaction object candidate is not located within a preset range including the position of the selected selected transaction object candidate within the evaluation axis area, It is also possible to determine the selected selection transaction object candidate as the selection transaction object.

In addition, the selection unit 33 divides the evaluation axis area into a plurality of areas, and randomly selects a transaction object without using the above-mentioned score so that each of the plurality of divided areas includes one selected transaction object. can also be determined.

In addition, there are four evaluation axes included in the evaluation axis area, the evaluation value for each item is 1, 2, 3, 4, or 5, and the position of the transaction object is (v1, v2, v3, v4). Suppose that it is shown as In (v1, v2, v3, v4), v1, v2, v3, v4 are evaluation values for each item in the four evaluation axes of the transaction object. In this case, for example, the selection unit 33 may decide as the selected transaction object a transaction object at a specific position in the evaluation axis area, such as (5, 0, 0, 1) or (4, 3, 2, 1). You can also do it.

Further, the selection unit 33 selects selected transaction objects such that the number of selected transaction objects is a predetermined number or less than a predetermined number. Thereby, it is possible to suppress the amount of transaction target information placed in the content from becoming too large.

Further, the selection unit 33 selects one or more transaction objects that the content provision target user has purchased in the past from among the plurality of transaction targets included in the target category, based on the user information of the content provision target user.

Further, the selection unit 33 selects a reference transaction object that is a reference transaction object. The reference transaction object is, for example, a transaction object placed at the center of the evaluation axis area or a transaction object highlighted in the evaluation axis area as a reference transaction object.

The selection unit 33 can select a reference transaction target based on the purchase history of the content provision target user. For example, the selection unit 33 can prioritize a transaction object with a higher number of purchases or purchase frequency among a plurality of transaction objects purchased by the content provision target user, and select the transaction object as the reference transaction object. Moreover, the selection unit 33 can prioritize the transaction object whose purchase time is newer among the plurality of transaction objects purchased by the content provision target user, and select the transaction object as the reference transaction object.

Further, the selection unit 33 can also select a reference transaction target based on the browsing history of the content provision target user. For example, the selection unit 33 can prioritize and select a transaction object with a higher selection frequency or selection frequency as a reference transaction object among a plurality of transaction objects selected by the content provision target user. Moreover, the selection unit 33 can prioritize and select a transaction object with a newer selection time as a reference transaction object among the plurality of transaction objects selected by the content provision target user.

Further, the selection unit 33 can also select a reference transaction target based on the user review history of the content provision target user. For example, the selection unit 33 can select, as the reference transaction object, a transaction object whose evaluation value according to the user review by the content provision target user is the center evaluation value of the area.

Further, the selection unit 33 selects, for example, a transaction object whose overall evaluation value for each item is at a medium position on each of a plurality of evaluation axes among a plurality of transaction objects that the content provision target user has purchased or viewed in the past, as a reference transaction. You can also select it as a target. For example, when the overall evaluation value for each item is a 5-level evaluation from 1 to 5, the average evaluation value for each item is a value within the range of 2.5 to 3.5. It is not limited to , and may be a value within the range of 2.8 to 3.2, or may be 3.

[3.3.4.4. Re-selection of transaction target according to enlargement operation]
When the receiving unit 31 receives an operation to enlarge the evaluation axis area, the selection unit 33 reselects a plurality of transaction targets in accordance with the enlargement operation.

For example, the selection unit 33 can reselect a larger number of transaction objects as the plurality of transaction objects corresponding to the enlargement operation than the number of transaction objects whose information was included in the content before the enlargement operation. For example, the selection unit 33 can select more transaction objects as the plurality of transaction objects according to the enlargement operation, as the enlargement rate of the enlarged area is larger.

In addition, in reselecting the transaction object, the selection unit 33 can preferentially select a transaction object with a higher ranking, or preferentially select a transaction object that the content provision target user has purchased in the past. .

Note that when the information provision request is received by the reception unit 31, the selection unit 33 selects transaction object candidates that are transaction object candidates to be placed in the evaluation axis area by a selection method similar to the selection method of the selected transaction object. You can select multiple items.

The selection unit 33 ranks each candidate for transaction according to the expansion rate of the evaluation axis area, and selects a plurality of candidates for transaction that have a rank equal to or higher than the expansion rate of the evaluation axis area among the multiple candidates for transaction. It can also be selected as a selected transaction target.

The rank according to the expansion rate of the evaluation axis area is, for example, 1 when the expansion rate of the evaluation axis area is the initial value (1x), 2 when the expansion rate of the evaluation axis area is 2x, and For example, when the expansion rate of the evaluation axis area is 2 times, it is set to 3. Regarding the rank according to the expansion rate of the evaluation axis area, for example, the smaller the value, the higher the rank.

[3.3.5. Providing Department 34]
The providing unit 34 selects a position within the area where the two or more evaluation axes selected by the selection unit 33 are shown and specified by the specifying unit 32 according to the evaluation value based on the user review. Generate content that arranges information on multiple transaction targets.

The information on the transaction object included in the content includes, for example, information indicating the name and identification code of the transaction object, image information on the transaction object, information indicating the price of the transaction object, and the like. If the transaction object is a product, the identification code is the model number of the product.

When two evaluation axes whose evaluation criteria have a predetermined relationship with each other are selected by the selection unit 33, the providing unit 34 selects two evaluation axes with high evaluation values based on user reviews in the evaluation axis area. The two directions are arranged in opposite directions.

Furthermore, the providing unit 34 highlights information on transaction objects that the content provision target user has purchased in the past, information on standard transaction objects, and the like out of information on a plurality of transaction objects included in the content. For example, highlighting can be done by increasing the size of the transaction target information compared to other transaction target information, increasing the thickness of the frame surrounding the transaction target information, or changing the color of the frame surrounding the transaction target information. Alternatively, this can be done by making the color within the frame a more noticeable color. Note that the highlighted display may be performed by blinking the information on the transaction target.

The providing unit 34 provides the generated content to the content provision target user by transmitting the generated content to the content provision target user's terminal device 2. The terminal device 2 displays content provided from the information providing device 1. Such content is content in which information on a plurality of transaction objects is arranged in a region where a plurality of evaluation axes are shown, at positions corresponding to evaluation values based on user reviews. Thereby, the content provision target user can easily grasp the position of each transaction target on each evaluation axis. Therefore, the information providing device 1 can improve convenience when a content provision target user selects a transaction target from among a plurality of transaction targets.

Further, as described above, the plurality of evaluation axes forming the evaluation axis area included in the content are selected based on the user information of the user to whom the content is provided. Therefore, content including a plurality of evaluation axes suitable for the user to whom the content is provided can be provided to the user to whom the content is to be provided. Thereby, the information providing device 1 can improve convenience when a content provision target user selects a transaction target from among a plurality of transaction targets.

FIG. 6 is a diagram showing an example of content provided by the information providing device 1 and displayed on the terminal device 2 according to the embodiment. In the content 60 shown in FIG. 6, an evaluation axis area 61 is formed by an evaluation axis for the item "moist", an evaluation axis for the item "refreshing", an evaluation axis for the item "foaming", and an evaluation axis for the item "creamy". .

The evaluation axis for the item "Moist" and the evaluation axis for the item "Refreshing" have a reciprocal relationship in their evaluation criteria, and these evaluation axes have high evaluation values based on user reviews in the evaluation axis area 61. are arranged so that their directions are opposite to each other. In addition, the evaluation axis for the item "foaming" and the evaluation axis for the item "creamy" have a relationship in which their evaluation criteria are related, and in the evaluation axis area 61, these evaluation axes have high evaluation values based on user reviews. are arranged so that their directions are opposite to each other.

In the content 60 shown in FIG. 6, information on each of product A, product B, product C, product D, product E, product F, product G, product H, and product I is stored in the evaluation axis area 61 as information on multiple transaction targets. It is located in

Product F is a transaction object that the content provision target user purchased in the past, and product H is a reference transaction object. Information on product F and information on product H are highlighted. Information on product F and information on product H are highlighted in different ways. In the example shown in FIG. 6, the information on product F is indicated by hatching in an emphasis color, and the information on product H is emphasized by increasing the thickness of the frame. Note that the information on product F and the information on product H only need to be highlighted in different ways, and are not limited to the example shown in FIG. 6. Note that the information on the reference transaction object does not need to be highlighted.

Product H is a standard transaction object as described above, and is placed in the center area of the evaluation axis area 61. In the example shown in FIG. 6, the product H is a transaction object whose evaluation value according to the user review by the content provision target user is the center evaluation value of the area.

The base point, which is the point where the evaluation axes are connected to each other, is, for example, the end or center of the evaluation axes. The end of the evaluation axis whose end is connected to the base point is the position where the evaluation value is the lowest on the evaluation axis, for example, the position where the median value of the evaluation values or the average value of the evaluation values is. Further, the central portion of the evaluation axis to which the central portion is connected is a position where the evaluation value is intermediate on the evaluation axis, for example, a position where the evaluation value is the median value or the average value of the evaluation values. That is, the base point, which is the point where each evaluation axis intersects, is a position where each evaluation value is intermediate.

Thereby, in the information providing device 1, the position where the evaluation on each of the plurality of evaluation axes is medium can be set as the center position of the evaluation axis area 61. In this case, the evaluation axis area 61 is an area of average or higher evaluation in each evaluation axis. For example, if the evaluation value for each item is in five stages from 1 to 5, the evaluation value for each item from 3 to 5 is This is an area of evaluation values, and does not include areas of evaluation values for each item that are less than 3.

Furthermore, the evaluation values at the end points of the evaluation axis for the item ``moist'' and the evaluation axis for the item ``refreshing'', which are obtained by dividing the evaluation axis for the item ``hair finish'' into two, are the evaluation values for the evaluation axis for the item ``hair finish''. median of the values, but is not limited to such examples.

Further, the base point, which is the point where each evaluation axis intersects, may be the evaluation value of the reference transaction object in each evaluation axis. Thereby, in the information providing device 1, the reference transaction object can be placed at the center of the evaluation axis area 61.

Note that the base point, which is the point to which each evaluation axis is connected, may be the position where each item-specific evaluation value is the lowest. The lowest position of the evaluation value for each item is 1 when the evaluation value for each item is in five stages from 1 to 5. Further, the base point, which is the point where each evaluation axis intersects, may be a position of a different evaluation value for each evaluation axis.

Further, the providing unit 34 may use, for example, an item evaluation value according to a user review by a content provision target user for the reference transaction object or an item evaluation value according to user reviews of a plurality of users U for the reference transaction object as a base point. can.

Furthermore, when the number of evaluation axes shown in the evaluation axis area 61 is two, the providing unit 34 can also arrange these two evaluation axes in the content 60 in a state where they are perpendicular to each other. For example, the providing unit 34 may be placed in the content 60 in a state where these two evaluation axes are perpendicular to each other at the center of the two evaluation axes.

Further, the position of the reference transaction object may be a position shifted from the center area of the evaluation axis area 61. In this case, the providing unit 34 can, for example, place the position of the reference transaction object in the central area of the content 60 instead of the position of the base point.

In the example shown in FIG. 6, each transaction object is placed at one position within the evaluation axis area 61, but the same transaction object may be placed at multiple positions within the evaluation axis area 61. For example, information about a product that foams very well and is very creamy is located at the position with the highest evaluation value on the evaluation axis for the item "foaming" and at the position where the evaluation value on the evaluation axis for the item "creaminess" is the highest. Placed.

When the enlargement operation is accepted by the reception unit 31, the providing unit 34 enlarges and displays information on the plurality of transaction targets corresponding to the enlargement operation selected by the selection unit 33 in the evaluation axis area 61 according to the enlargement operation. The content 60 placed in the area is generated. The providing unit 34 then transmits the generated content 60 to the terminal device 2. Thereby, the providing unit 34 can provide the content provision target user with the content 60 in which information on a plurality of transaction targets is arranged in an area that is enlarged and displayed in accordance with the enlargement operation.

FIG. 7 is a diagram showing an example of a state when the content 60 shown in FIG. 6 is enlarged. The example shown in FIG. 7 shows how the evaluation axis area 61 has been expanded around the information of product F. Compared to the state shown in FIG. information, product K information, product L information, and product M information have been added.

In this way, the information on the plurality of transaction objects corresponding to the enlargement operation selected by the selection unit 33 is, for example, the information on the plurality of transaction objects whose information was included in the content 60 before the enlargement operation in the area after the enlargement operation. This is information about a larger number of transaction objects than the number of transactions. As a result, the content provision user can learn more detailed information about the transaction object by zooming in, and the convenience for the content provision user when selecting the transaction object from among multiple transaction objects can be improved. can.

Further, the providing unit 34 can also increase the number of types of information on a plurality of transaction objects arranged in the evaluation axis area 61, for example, compared to the content 60 before the enlargement operation. The types of information on the transaction object include, for example, specific information indicating the name and identification code of the transaction object, image information on the transaction object, price information indicating the price of the transaction object, evaluation information indicating the evaluation by the user U of the transaction object, There is characteristic information regarding the characteristics of the transaction object. The evaluation information includes, for example, at least one of information on the overall evaluation value of the transaction object and information on the evaluation value for each item.

For example, assume that the information to be traded in the content 60 before the enlargement operation is specific information, image information, and price information. In this case, the providing unit 34 adds evaluation information, characteristic information, and the like, in addition to specific information, image information, and price information, as the types of information on the plurality of reselected transaction targets, for example. In other words, the providing unit 34 causes the content 60 after the enlargement operation to have a larger amount of transaction target information than the content 60 before the enlargement operation. As a result, the content provision user can learn more detailed information about the transaction object by zooming in, and the convenience for the content provision user when selecting the transaction object from among multiple transaction objects can be improved. can.

[4. Processing procedure]
Next, a procedure of information processing by the processing unit 12 of the information providing device 1 according to the embodiment will be explained. FIG. 8 is a flowchart showing an example of the flow of information processing by the processing unit 12 of the information providing device 1 according to the embodiment.

As shown in FIG. 8, the processing unit 12 determines whether the position determination timing has arrived (step S10).

When it is determined that there is an enlargement operation (step S17: Yes), the processing unit 12 reselects a plurality of transaction objects to be placed in an enlarged area that is an area enlarged by the enlargement operation, and selects the plurality of transaction objects that are reselected. The content 60 including the information in the enlarged area is transmitted to the terminal device 2 (step S18).

When the process of step S18 is completed, or when it is determined that there is no enlargement operation (step S17: No), the processing unit 12 determines whether or not the operation end timing has come (step S19). For example, when the power of the information providing device 1 is turned off, or when it is determined that an end operation has been performed by operating an operation section (not shown) of the information providing device 1, the processing section 12 determines the operation end timing. It is determined that it has become.

If the processing unit 12 determines that the operation end timing has not come (step S19: No), the process proceeds to step S10, and if it determines that the operation end timing has come (step S19: Yes), the process proceeds to FIG. The indicated process ends.
