The server device that communicates with the information processing device 200 may be a server device managed by each store or the like.

[0046] Next, the functional configuration of each device included in the information processing system 100 of this embodiment will be described with reference to Fig. 7. Fig. 7 is a diagram illustrating the function of each device included in the information processing system.

[0047] The information processing device 200 of this embodiment includes a visualization processing unit 250. The functions of the visualization processing unit 250 of this embodiment are realized by a CPU 201 included in the information processing device 200 reading and executing a program stored in a ROM 202, a RAM 203, or the like.

[0048] The visualization processing unit 250 includes an input receiving unit 251 , a vector conversion unit 252 , a group generation unit 253 , and a screen generation unit 254 .

[0049] The input receiving unit 251 receives various inputs to the information processing device 200. The vector conversion unit 252 converts the user characteristic information, store characteristic information, and product characteristic information into vector representations of the users, stores, and products based on the log information, and expresses them in a single vector space. In other words, the vector conversion unit 252 maps multiple types of entities onto a single vector space based on linking information that links the feature information of each entity.

[0050] More specifically, the vector conversion unit 252 maps multiple types of entities onto a vector space learned by one of the following methods.

[0051] Method 1: Item2Vec: Neural Item Embedding for Collaborative Filtering Method 2: Billion-scale Commodity Embedding for E-commerce Recommendation in Alibaba Method 3: DTCDR: A Framework for Dual-Target Cross-Domain Recommendation Method 4: Cross-Domain Recommendation: An Embedding and Mapping Approach

[0052] In this embodiment, when an entity is selected in a vector space in which multiple types of entities are mapped, the group generation unit 253 creates a group according to the selected entity. Furthermore, when a search condition for feature information is input, the group generation unit 253 may group entities identified from the search results based on the search condition into one group.

[0053] The screen generation unit 254 compresses the vector space onto which the multiple types of entities are mapped by the vector conversion unit 252 into a low-dimensional space (two or three dimensions), and generates screen data to be displayed on the terminal device 300.

[0054] Furthermore, the screen generation unit 254 controls the display of the terminal device 300 in response to various operations on the terminal device 300. In other words, the screen generation unit 254 is an example of a display control unit.

[0055] Next, a description will be given of the functions of the terminal device 300. The terminal device 300 of this embodiment has a communication control unit 310 and a display control unit 320. The communication control unit 310 controls communication between the terminal device 300 and the information processing device 200. The display control unit 320 controls display on a display device included in the terminal device 300.

[0056] Next, the processing of the information processing device 200 of this embodiment will be described with reference to Fig. 8. Fig. 8 is a flowchart illustrating the processing of the information processing device.

[0057] In the information processing device 200 of this embodiment, the input receiving unit 251 of the visualization processing unit 250 determines whether a display request for a vector space in which multiple types of entities are mapped has been received (step S801). If a display request has not been received in step S801, the information processing device 200 waits.

[0058] In step S801, when a display request is received, the visualization processing unit 250 visualizes the vector space and displays it on the terminal device 300 (step S802). In other words, the visualization processing unit 250 causes the screen generation unit 254 to generate screen data for displaying the vector space onto which multiple types of entities have been mapped by the vector conversion unit 252, and causes the terminal device 300 to display it.

[0059] Next, the visualization processing unit 250 determines whether or not an operation to select an entity has been performed on the terminal device 300 (step S803). If an operation to select an entity has not been performed in step S803, the visualization processing unit 250 may end the process.

[0060] In step S803, when an operation to select an entity is performed, the group generation unit 253 creates a group according to the selected entity (step S804).

[0061] Specifically, the group generation unit 253 may group together entities that are different in type from the selected entity and have affinity with the selected entity. The affinity entities may be entities whose distance from the selected entity is within a predetermined range in the vector space.

[0062] Next, the visualization processing unit 250 causes the screen generating unit 254 to generate screen data for displaying information related to the generated group, and causes the terminal device 300 to display the screen data (step S805).

[0063] Display examples of this embodiment will be described below with reference to Figures 9 and 10. Figure 9 is a first diagram showing a display example of a terminal device.

[0064] The screen 301 shown in FIG. 9 may be displayed on the terminal device 300 by, for example, the processing of step S802 in FIG.

[0065] On screen 301, multiple types of entities, such as users, stores, and products, are each mapped onto a single vector space.

[0066] The screen 301 also includes a display area 91, in which information indicating the correspondence between the types of entities mapped onto the vector space and the dots displayed on the screen 301 is displayed.

[0067] Furthermore, the screen 301 of this embodiment displays an input field 92. In this embodiment, when identification information of an entity that serves as a search key is entered in the input field 92 and a search button is operated, information indicating the position of the entity whose identification information has been entered in the vector space displayed on the screen 301 may be displayed.

[0068] More specifically, for example, when a store ID is entered in the input field 92 as identification information for specifying an entity, the dot corresponding to the entered store ID may be displayed in a different manner from other dots on the screen 301. In this way, the user of the terminal device 300 can visually grasp the degree of affinity between the desired entity and other entities.

[0069] In addition, in this embodiment, when a dot is selected on the screen 301, feature information of the entity corresponding to the selected dot may be displayed on the screen 301.

[0070] In FIG. 9, display area 93 is an example of a display area that is displayed when dot D1 is selected, display area 94 is an example of a display area that is displayed when dot D2 is selected, and display area 95 is an example of a display area that is displayed when dot D3 is selected.

[0071] The type of entity indicated by the dot D1 is a user. The dot D1 also indicates a user identified by the user ID "a." Therefore, the display area 93 displays the user characteristic information associated with the user ID "a."

[0072] The type of entity indicated by dot D2 is a store. Dot D2 also indicates a store identified by store ID "3." Therefore, the display area 94 displays store characteristic information associated with store ID "3."

[0073] The type of entity indicated by the dot D3 is a product. The dot D3 also indicates a product identified by the product ID "11." Therefore, the display area 95 displays the product feature information associated with the product ID "11."

[0074] In this embodiment, when an entity is selected, the feature information of the selected entity is displayed. Therefore, according to this embodiment, the user of the terminal device 300 can understand the features of the selected entity.

[0075] In this embodiment, the screen 301 may include an operation button for instructing the generation of a group including a selected dot. In this case, when an operation for selecting a dot is performed on the screen 301 and then an operation for instructing the generation of a group is performed, the information processing device 200 may generate a group including an entity corresponding to the selected dot and entities that have a high affinity with this entity.

[0076] When a group is generated, the information processing device 200 may hold, as group information, a list of identification information for identifying entities included in the group.

[0077] In this way, by generating a group including the selected entity, it is possible to allow the user of the terminal device 300 to know, for example, stores, products, etc. that have a high affinity with a certain user.

[0078] In this embodiment, for example, when an instruction to create a group is received, the types of entities included in the group may be identified, which makes it possible to identify users whose attributes are similar to those of a certain user.

[0079] Furthermore, in this embodiment, when entities are grouped, the terminal device 300 may display the results of statistical processing performed on the feature information of each of the grouped entities as information about the group.

[0080] 10 is a second diagram showing an example of a display on the terminal device 300. The screen 302 shown in FIG. 10 may be displayed on the terminal device 300 by, for example, the processing in step S805 in FIG.

[0081] The screen 302 includes display areas 101 and 102. The display area 101 may display a list of generated groups. The display area 102 may display information about a group selected from the list displayed in the display area 101.

[0082] In the example of FIG. 10, "Group AB" is selected from the list of groups displayed in display area 101, and information about group AB is displayed in display area 102.

[0083] Specifically, the information about the group may be, for example, information indicating the number of users who have purchased a certain product, the total purchase amount of the product for each user, etc. By displaying such information, the user of the terminal device 300 can understand the affinity between the product characteristics indicated by the product characteristic information and the user characteristics indicated by the user characteristic information. Therefore, it is possible to provide the user of the terminal device 300 with information about suppliers, etc., and to propose campaigns, etc.

[0084] Furthermore, the information about the group may include the number of visitors by age group at a certain store. By displaying such information, the user of the terminal device 300 can understand the affinity between the store characteristics indicated by the store characteristic information and the user characteristics indicated by the user characteristic information. Therefore, in this embodiment, the user of the terminal device 300 can be assisted in appropriately using outdoor advertisements near the store and advertisements at the store entrance and inside the store.

[0085] In this embodiment, the entity types are users, stores, and products, but the entity types in this embodiment are not limited to these. The entity types in this embodiment may be any type as long as linking information linking the feature information of each entity can be obtained.

[0086] 9 and 10 are displayed on the terminal device 300 in this embodiment, but the present invention is not limited to this. The screens 301 and 302 may be displayed on the display device 205 of the information processing device 200.

[0087] As described above, according to this embodiment, if the user of the terminal device 300 is a store manager or the like, he or she can acquire hypotheses for improving stocking amounts and shelf allocations.

[0088] Although the present invention has been described above based on the embodiments, the present invention is not limited to the requirements shown in the above embodiments. These requirements can be changed without departing from the spirit of the present invention, and can be appropriately determined depending on the application form. [Explanation of symbols]
