[0045] The embodiments of the present disclosure provide a method for processing resource data, which can be applied to, for example, Figure 1In the application environment shown. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or can be placed on the cloud or other network servers. Among them, the terminal 102 can be, but is not limited to, various personal computers, laptop computers, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart in-vehicle devices, etc. The portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The server 104 can be implemented by an independent server or a server cluster composed of multiple servers.

[0046] In some embodiments of the present disclosure, as Figure 2 shown, a method for processing resource data is provided. Taking the example that this method is applied to Figure 1 the server in to process resource information for illustration. It can be understood that this method can be applied to the server, and can also be applied to a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. In a specific embodiment, the method may include the following steps:

[0047] S202: Obtain the resource information of at least one target object; wherein, the resource information includes the target user information in the target object and the resource data included in each target user.

[0048] The target object can be an enterprise in the enterprise equity scenario. The resource information includes the target user information in the target object and the resource data included in each target user. The target user can be a shareholder of the enterprise, and the target user information can be the basic information about the shareholder, such as whether the shareholder is a natural person or a legal person, the name, address, contact information, etc. of the shareholder. The resource data included in each target user can be the data related to equity owned by the shareholder, such as the equity share held by the shareholder and the equity trading history of the shareholder.

[0049] S204: Build a link based on the resource information. The nodes in the link include a root node and child nodes. The root node represents the target object, the child nodes represent the target users, and the links between the root node and the child nodes and the links between the child nodes represent the resource data included in the target users.

[0050] Figure 3Schematic diagram of a link in an embodiment. The link shows the context of the internal equity control relationship within an enterprise. Through the link, the associations based on resource data among the enterprise from the root node to the child nodes and among the shareholders can be clearly seen. The root node represents the target object, that is, the enterprise itself, namely point A, which is the starting point of the entire link. It extends outward with the enterprise as the core to display its internal equity structure. The child nodes represent the target users, that is, the shareholders of the enterprise, which can be points B, C, D, etc. in Figure 3 such as B, C, D, etc. Each child node corresponds to a shareholder. Through the link connections with the root node and other child nodes, the position and role of the shareholder in the enterprise's equity structure are reflected. The link between the root node and the child nodes reflects the equity relationship between the enterprise and the shareholders, which can include resource data such as the number and proportion of the enterprise's equity held by the shareholders. For example, the link between point A and point B may show that B holds 70% of the equity of enterprise A. The link between the child nodes shows the associations among the shareholders based on the equity resource data. For example, if shareholders B and C jointly hold the equity of another enterprise A, the link between them can reflect the equity cooperation or competition relationship, etc. in enterprise D.

[0051] S206: Obtain the target user corresponding to the target resource data based on the link.

[0052] Starting from the root node representing the enterprise, along the lines representing the equity relationship in the link, according to the target resource data, obtain the target user corresponding to the target resource data.

[0053] In the above method for processing resource data, by constructing a link, through continuous recursive penetration calculation, link-type data is formed until the final node is penetrated. All links are compared and judged to select the optimal path, and the target user corresponding to the target resource data is obtained based on the link. The relationships among the target users are fully considered, improving the accuracy of the calculation results of the control relationships among enterprises.

[0054] In some embodiments of the present disclosure, the obtaining of the resource information of at least one target object includes:

[0055] Label the target users in the resource information and the resource data included by the target users, and convert the resource data in different formats into a unified standard format to obtain the resource information after data cleaning.

[0056] Obtain the resource information of at least one target object, and label the target users in the resource information and the resource data included by the target users. For example, in the enterprise equity scenario, clearly label the identity information of each shareholder, as well as resource data such as the number of equity held, the equity proportion, and the equity change records. At the same time, for resource data in different formats, it will be converted into a unified standard format. Figure 4 Schematic diagram of resource data processing in an embodiment.

[0057] In some embodiments of the present disclosure, the process of constructing the link includes:

[0058] Obtain a first correspondence and a second correspondence, where the first correspondence includes a first target user corresponding to the target object, and the second correspondence includes a second target user corresponding to the first target user;

[0059] Obtain the resource data included in the first target user and the second target user;

[0060] Construct a link based on the resource data, the first correspondence, and the second correspondence.

[0061] The first correspondence includes the correspondence between the target object and the corresponding first target user. For example, for enterprise A, its first target users may be shareholders B, C, and D, and a first correspondence between enterprise A and shareholders B, C, and D is established. The second correspondence includes the correspondence between the first target user and the second target user. The first target user can be a direct shareholder, and the second target user can be a shareholder of the direct shareholder, or a subject having a controlling relationship with the direct shareholder. For example, shareholder B may include shareholders E and F, then the relationship between B and E, F is the second correspondence. According to the obtained resource data, the first correspondence, and the second correspondence, a link is constructed. Taking the target object as the root node, the first target user and the second target user as child nodes, and connecting them with a link. At the same time, the corresponding resource data is reflected in the link. Connect enterprise A, shareholder B, and shareholder E with a line, and mark resource data such as the equity ratio next to the line, thus constructing a link that can clearly show the control relationship between enterprises.

[0062] In some embodiments of the present disclosure, the obtaining of the target user corresponding to the target resource data based on the link includes:

[0063] Identify from the root node upwards to determine the upper-level node of each node;

[0064] When there is a link between the target node and multiple nodes, determine the upper-level node of the target node based on the resource data represented by the link;

[0065] When the target node has no upper-level node, the target node is the target user corresponding to the target resource data.

[0066] In the enterprise - to - enterprise control relationship link, the root node represents the entire enterprise. According to the hierarchical relationship, the upper - level node of each node can be determined one by one from bottom to top. For example, in the enterprise equity link, start from the bottom - most shareholder node and find its direct shareholding party, which is the upper - level node. For instance, if the bottom - most shareholder E holds a part of the shares of shareholder B, then shareholder B is the upper - level node of shareholder E. When a target node has links with multiple nodes, it is necessary to determine its upper - level node based on the resource data represented by the links. In the enterprise equity scenario, the resource data mainly refers to information such as shareholding ratios. For example, if the target node shareholder D has links with both shareholder H and shareholder I, then it is necessary to judge according to the resource data such as the shareholding ratios between shareholder D and shareholder H, and shareholder D and shareholder I respectively. If shareholder H has a higher shareholding ratio in shareholder I and is more dominant in the control relationship, then shareholder H is determined as the upper - level node of shareholder I.

[0067] In some embodiments of the present disclosure, the sub - nodes include leaf nodes and intermediate nodes;

[0068] The leaf nodes include target users whose resource data cannot be split, and the intermediate nodes include target users whose resource data can be split.

[0069] As the nodes representing target users in the link, the sub - nodes are further divided into leaf nodes and intermediate nodes. Leaf nodes refer to target users whose resource data cannot be split. In terms of enterprise equity, they are those shareholders who cannot be further traced to their underlying shareholders or controlling entities. Intermediate nodes represent target users whose resource data can be split. Corresponding to enterprise equity, they are those shareholders who have other shareholders or controlling entities behind them.

[0070] In some embodiments of the present disclosure, the method further includes:

[0071] When the resource data of the intermediate node is greater than the first threshold, the intermediate node is the target user;

[0072] When the resource data of the intermediate node is less than the first threshold, based on the link, all the nodes of the target object are determined, and the target resource data of the target objects included in different nodes is calculated by the multiplication method;

[0073] Based on the target resource data, the target user is obtained.

[0074] When the resource data owned by an intermediate node is greater than a preset first threshold, this intermediate node is directly identified as the target user. If the resource data of the intermediate node is less than the first threshold, at this time, it is necessary to determine all nodes of the target object based on the constructed link, and then calculate the target resource data of the target object included in different nodes by means of multiplication. After calculating the target resource data of each node, the target user is determined according to these data. Figure 5 It is a schematic diagram of resource data processing in an embodiment.
