The embodiment of the invention discloses a structured entity recording method and device, a server and a storage medium. The structured entity recording method comprises the steps that candidate entities related to structured entities to be recorded are selected from a knowledge graph, the structured entities to be recorded are determined as associated entities according to priori attribute information of the type to which the candidate entities belong and a preset model, the associated entities and the candidate entities are merged, and the associated entities are recorded into the knowledgegraph. According to the embodiment of the invention, the problems are solved that when an existing knowledge map records entities, since entity analysis is conducted on existing entities in the knowledge graph once in the process of adding one entity, the calculation amount is large, the consumed time is long, and the accuracy of entity analysis is not high; the candidate entities are selected, and then prior knowledge is utilized to fuse the preset model so that the efficiency and accuracy of entity association can be effectively improved; the calculation amount is reduced, and therefore theknowledge graph can easily and efficiently record the structured entities.

A method, device and apparatus for combining different instances describing the same entity. The method comprises: acquiring a connection diagram comprising a plurality of instances (S110), wherein different nodes in the connection diagram indicate different instances, and connecting lines between the nodes indicates an instance relationship between the instances corresponding to the nodes; identifying, from the connection diagram and on the basis of the instance relationship, different instances describing the same entity, merging the nodes corresponding to the identified instances and updating the connection diagram (S120); identifying from the updated connection diagram a pair of instances having an undiscovered instance relationship existing therebetween, and adding a connecting line so as to connect the nodes corresponding to the pair of instances (S130); and iteratively executing the steps of updating the connection diagram on the basis of the instance relationships and adding connecting lines in the updated connection diagrams, until a specified condition is satisfied (S140). The method can more fully identify different instances describing the same entity.

The invention relates to a data processing method and device, electronic equipment and a storage medium. The method comprises the following steps: converting attribute information of each node in a target knowledge graph network into space vector characteristics represented by numerical values to obtain an entity attribute characteristic matrix; Obtaining a Laplacian matrix representing an entityrelationship graph of each node in the target knowledge graph network; Determining the final vector space representation of each node in the target knowledge map network according to the entity attribute feature matrix and the Laplace matrix; Calculating the final vector similarity between every two nodes in the target knowledge graph network; And fusing the node pairs of which the vector similarity calculation results are greater than a preset threshold value. According to the method, the attribute information and the adjacency information of the entities in the knowledge graph are used for learning entity vector space representation, more comprehensive and accurate vector representation can be obtained, and the problem of inaccurate entity similarity calculation caused by entity attribute loss and attribute value change is avoided.

The invention provides a cross-community potential person relationship analysis method based on weak trusted data. The method does not depend on a character attribute label unsupervised entity identification method to extract an entity; the similarity of user nodes in different attribute communities is measured by using a hierarchical structure, a multilayer graph is constructed to encode the structural similarity, and a structural network relation graph formed by clustering different characteristics by users with multiple identity characteristics is generated for the nodes, so that potentialperson relations which are uncorrelated on the network and may be similar in reality are discovered. Besides, based on a user correlation coefficient algorithm, the method has obvious advantages in discovering the potential relationship between two user nodes without direct edge connection, and is high in accuracy.

The invention discloses a method and apparatus for combining different examples for describing the same entity and equipment. The method comprises the steps that a connection drawing including multiple examples is acquired, wherein different nodes in the connection drawing represent different examples, the connecting lines among the nodes represent the example relation of the corresponding examples; the different examples for describing the same entity in the connection drawing are identified based on the example relation, the nodes corresponding to the identified examples are combined, and the connection drawing is updated; example pairs having no example relation are identified in the updated connection drawing, and the connecting lines for connecting nodes corresponding to the example pairs are added; the step of updating the connection drawing based on the example relation and the step of adding the connecting lines in the updated connection drawing are executed in an iterated mode till the specified conditions are met. The example pairs describing the same entity can be more fully excavated by utilizing the method, the apparatus and the equipment.
