Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0022] Optionally, the virtual item recommendation method provided in this embodiment can be applied to a hardware environment consisting of a terminal and a server.

[0024] The virtual item recommendation method of the embodiment of the present application can be executed by a server, a terminal, or a server and a terminal together. The terminal can also execute the virtual item recommendation method of the embodiment of the present application by a client installed thereon.

[0025] Taking the method for recommending virtual items in this embodiment executed by the server as an example, Figure 1 The following is a flowchart of a method for recommending virtual items provided in an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0026] Step S102, constructing multiple virtual items in the metaverse;

[0027] The execution subject of the virtual item recommendation method provided in the present application is a virtual item recommendation device, and the virtual item recommendation device can be a hardware device such as a terminal device or a server, or software installed on a hardware device.

[0028] The embodiment of the present application is explained by taking the server as the execution subject as an example. The server can be an independent server, or it can be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (Content Delivery Network, CDN), and big data and artificial intelligence platforms. The embodiment of the present application can acquire and process relevant data based on artificial intelligence technology. Among them, artificial intelligence (Artificial Intelligence, AI) is the theory, method, technology and application system that uses digital computers or machines controlled by digital computers to simulate, extend and expand human intelligence, perceive the environment, acquire knowledge and use knowledge to obtain the best results.

[0029] Step S104, determining style type information corresponding to each virtual item;

[0030] Step S106, constructing a virtual item association graph according to the plurality of virtual items and the style type information corresponding to each virtual item;

[0031] Step S108, recommending a target virtual item from among multiple virtual items to a target virtual object in the metaverse according to the virtual item association graph.

[0032] In an alternative embodiment, Figure 2 A flowchart of a clothing recommendation method provided in a specific embodiment of the present application is shown as follows: Figure 2 As shown, taking clothing recommendations in the metaverse as an example, by establishing a knowledge graph of clothing, a clothing store in the metaverse is constructed, and AI clothing recommendations are made to users based on their active preferences or dressing habits.

[0033] Through the virtual item recommendation method provided in the embodiment of the present application, virtual items are first constructed in the metaverse, and then a virtual item association map is constructed based on the virtual items and the corresponding style types. Virtual objects in the metaverse are recommended based on the virtual item association map, which solves the technical problem that virtual items cannot be accurately recommended to users due to the large number of virtual items in the metaverse.

[0034] In an optional embodiment of the present case, the above step S102 includes: taking each virtual item among the multiple virtual items as the first virtual item, and obtaining item information corresponding to the first virtual item; wherein the item information at least includes style type information corresponding to the first virtual item; using a preset three-dimensional modeling model in the metaverse, constructing an initial three-dimensional model of the first virtual item according to the item information; generating the first virtual item by rendering the initial three-dimensional model; wherein the first virtual item carries the style type information corresponding to the first virtual item.

[0035] Optionally, the item information in this embodiment further includes size information corresponding to the first virtual item, weight information corresponding to the first virtual item, material information corresponding to the first virtual item, and process information corresponding to the first virtual item.

[0036] In this embodiment, virtual items take clothing in the Metaverse as an example. For each piece of clothing, its specific production is firstly to create clothing through the artist's description, and then to construct the specific clothing through 3D modeling, rendering and other technologies in the Metaverse, and then display it to the user. Moreover, in addition to the appearance, style, version, size, actual texture, weight, materials, etc., each piece of clothing is different in terms of craftsmanship. The specific influencing factors are determined by the corresponding technical process supplier to set different item information.

[0037] Furthermore, before the above step S108, it also includes: taking each virtual item among the multiple virtual items as a second virtual item, and determining item information corresponding to the second virtual item; constructing at least one virtual sensor module according to at least one item information type corresponding to the item information of the second virtual item, so that when the second virtual item is displayed on the target virtual object, the item information corresponding to the second virtual item is sent to the target virtual object through the at least one virtual sensor module.

[0038] As we all know, the metaverse is a virtual world that is linked and created by scientific and technological means, mapped and interacted with the real world, and has a digital living space for a new social system. The metaverse is essentially a virtualization and digitization process of the real world, which virtualizes the characters in the real world into virtual characters in the metaverse. In reality, when users enter a clothing store to try on clothes, they pay great attention to the feeling of the clothes to the users. Users experience the texture and comfort of the clothes through perception. However, in the metaverse, multiple sensor modules can be constructed according to the information type of the item information. For example, if the information type of the item information is weight information, a sensor module for measuring weight information is constructed; for another example, if the information type of the item information is material information, a sensor module for measuring the material of the item is constructed, and so on. After sending the item information to the virtual object through at least one sensor module, it is equivalent to that the virtual character in the metaverse can also perceive the texture and comfort of the clothes. Users can achieve completely different effects for each piece of clothing through various sensors and metaverse hardware technology, thereby improving the experience of virtual characters trying on clothes.

[0039] In an optional embodiment of the present case, the above-mentioned step S106 includes: extracting each first entity corresponding to each virtual item, and extracting each second entity corresponding to the style type information corresponding to each virtual item; by performing knowledge fusion on at least two second entities with the same style type, so as to obtain at least one third entity corresponding to the style type information corresponding to multiple virtual items; wherein the number corresponding to the at least one third entity is less than or equal to the number corresponding to the second entity; taking at least one third entity as at least one main node, and taking the second entity corresponding to the virtual item associated with each third entity as a child node, and using directed edges to represent the association relationship between at least one main node and the child nodes associated with each main node, so as to construct a virtual item association graph.

[0040] The core of this application is to realize AI outfit recommendation by combining various technologies such as the Metaverse Knowledge Graph. For the acquired virtual item data, named entity recognition is used to extract the entity corresponding to each virtual item (i.e., the first entity mentioned above), and the entity corresponding to the style type of each virtual item (i.e., the second entity mentioned above). For entities of the same style type, i.e., repeated third entities, knowledge fusion is performed to detect several style types corresponding to multiple virtual items. Then, one style type is used as the main node, and the virtual items belonging to this style type are used as child nodes. The relationship between the main node and the child nodes is represented by directed edges, thereby constructing a knowledge graph of virtual items (i.e., the above-mentioned virtual item association graph).

[0041] In a specific example of this embodiment, taking the virtual item as clothing in the metaverse as an example, Figure 3 The clothing atlas provided in the embodiments of the present application, such as Figure 3 As shown, in the knowledge graph, clothing categories are used as the main nodes in the knowledge graph, and specific sub-nodes are expanded based on these main nodes. Each sub-node is a specific clothing item.

[0042] For example, the style types include leisure, sports, current trends (fashion), accessories, shoes and boots, etc., which are not listed exhaustively; it should be noted that due to space limitations, Figure 3 Only some clothing categories are shown in the table. For example, uniforms are divided into men's uniforms and women's uniforms. There are many types of uniforms here, including evening gowns, social clothes, tuxedos, etc., and only gender classification is done here; the current trend is divided into suits, single items, customization, etc. Due to the special clothing of the times, the trend is temporarily divided into suits, single items and designer's ingenuity customization; leisure is divided into bottoms, suits, tops, etc.; sports are divided into lower body sportswear, upper body sportswear, etc.

[0043] Furthermore, after constructing a virtual item association graph according to multiple virtual items and style type information corresponding to each virtual item, it also includes: establishing a virtual shop in the metaverse according to the virtual item association graph, so that multiple virtual items in the virtual item association graph can be virtually traded in the virtual shop; after receiving a virtual item transaction request from a target virtual object, executing an operation corresponding to the virtual item transaction request based on the blockchain in the virtual shop.

[0044] In this embodiment, the virtual item association graph constructed in combination with the knowledge graph is used to place these virtual items in the constructed virtual store, such as Figure 3 The Metaverse clothing store shown in the figure, after the knowledge graph is established, there will be corresponding specific clothing and matching in the clothing model associated with the knowledge graph. The constructed clothing model is combined with blockchain technology to realize the clothing store in the Metaverse. You can choose your favorite clothing in the store. The underlying structure of the clothing is the clothing model associated with the knowledge graph.

[0045] Furthermore, after receiving a virtual item transaction request from a virtual object, the blockchain technology can be used to realize the transaction of virtual items in the virtual shop in the metaverse.

[0046] In an optional embodiment of the present case, the above-mentioned step S108 includes: receiving a first selection instruction from the target virtual object; wherein the first selection instruction is used to instruct the selection of a specified style type from a plurality of style types in a virtual item association map; in response to the first selection instruction, searching for a plurality of third virtual items associated with the specified style type from the virtual item association map, and displaying the plurality of third virtual items; receiving a second selection instruction from the target virtual object; wherein the second selection instruction is used to instruct the selection of a target virtual item from a plurality of third virtual items; in response to the second selection instruction, recommending the target virtual item to the target virtual object.

[0047] In this embodiment, virtual items can be recommended based on the user's own preferences. Taking clothing as an example, Xiao Ming likes to wear casual clothing, and the node in the knowledge graph of casual clothing is selected. After selection, the favorite clothing can be viewed in the model store of the metaverse (i.e., the above-mentioned virtual store).

[0048] In an optional embodiment of the present case, the above-mentioned step S108 includes: obtaining item label information corresponding to the fourth virtual item in the virtual item association map used by the target virtual object within a historical preset time period; wherein the item label information is used to identify the style type information corresponding to the fourth virtual item, and the item label information corresponds to the style type information one-to-one; counting the frequency of each item label within the historical preset time period; determining the target style type corresponding to the item label with the highest frequency; searching for multiple virtual items corresponding to the target style type from the virtual item association map, and recommending the multiple virtual items corresponding to the target style type to the target virtual object.

[0049] In this embodiment, AI recommendations are derived from the usage records of virtual items over a period of time in the virtual object's history to learn the user's habits and preferences, and then make recommendations for the user.

[0050] In specific implementation, the user's clothing outfits for one month are recorded, and clothing combinations are recommended based on the user's recent dressing habits. Every time the user chooses clothes in the Metaverse clothing store, a clothing label will be added. This label corresponds to the clothing model associated with the knowledge graph, which is the main node on the knowledge graph - the clothing category. Automatic clothing combinations are recommended to users based on the number of times the label is added.

[0051] For example, in the past month, a user wore sportswear the most, so the AI ​​system would recommend the user the main nodes related to sports. The main nodes would be expanded one by one, and finally the expanded related clothing would be presented to the user to achieve the purpose of recommendation.

[0052] Because many clothes and clothing in reality cannot be made so detailed, but 3D modeling rendering and painters can show the clothing in the metaverse, which will surely cause a fashion trend in the metaverse, and there will inevitably be clothing matching recommendations. This application will use knowledge graphs and metaverse AI blockchain and other technologies to realize this creativity.

[0053] Through the above-mentioned implementation steps, the embodiment of the present application integrates the knowledge graph with blockchain and other technologies in the metaverse, expands the content creation of the metaverse, and provides a metaverse solution. It can at least solve the problem of too many types of clothing in the metaverse, which is complicated and difficult to meet user selection, and solve the problem that people / users in the metaverse have difficulty in making decisions about the various clothing combinations in the metaverse.
