The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application.

Research shows that the arrival of the big data era generates a large amount of real-time data streams with large volume, multiple types and various structures, and the data sources are complicated (different types of relational databases), and the structures are heterogeneous (SQL, NoSQL databases, text files, Hive big data and the like). The integration and fusion of multi-source heterogeneous data are an important ring in the entity linking process. Therefore, how to accurately determine the link result of the entity becomes a problem to be solved urgently.
Based on this, the embodiment of the application provides a management method for entity link relations, which is helpful for improving the accuracy of search results and saving the search time of users.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for managing an entity link relationship according to an embodiment of the present disclosure. As shown in fig. 1, a method for managing an entity link relationship provided in an embodiment of the present application includes:
s101, acquiring entity information of the entity to be linked, which is input by a user.
In the step, the entity information of the entity to be linked, which is input in the client by the user, is obtained.
Here, the entity information input by the user may be a sentence, a word, etc.
S102, acquiring a plurality of pieces of description information of the entity to be linked from different databases based on the entity information.
In this step, based on the entity information input by the user, a plurality of pieces of description information describing the entity to be linked, which the user wants to search, are acquired from different databases.
Here, there is heterogeneity between description information acquired from different databases, where heterogeneity means that different data sources have different representations of the same concept or attribute, and semantic heterogeneity exists, and for example, regarding the concept of "product", some data sources are represented by "product", some are represented by "article", and for example, regarding the category attribute of product, some data sources are represented by "belonging category", some are represented by "category", and some are represented by "classification", and further, there are problems such as cross-language of description information acquired from different databases.
S103, generating an entity link diagram of the entity to be linked based on the plurality of pieces of description information.
In this step, because the description information of the same entity has certain difference due to different databases, and certainly, the description information acquired by different databases has the problems of crossing and repetition, an entity link map corresponding to the entity to be linked needs to be generated based on the acquired pieces of description information in order to obtain more comprehensive description of the entity to be linked.
Here, the information in the entity link graph is generally based on a data specification as a premise, that is, in the case that information about attributes, name descriptions and the like of entities to be linked is consistent, it is determined whether a plurality of pieces of description information describe the same entity to be linked, and if so, the plurality of pieces of description information are converted into entity nodes and are fused. For example, there may be a product "name: apple, category: handset ", there may be a product" name: apple, category: fruit' and entity linking refers to judging whether a plurality of pieces of description information acquired from different databases refer to entities to be linked, and generating an entity link diagram corresponding to the entities to be linked after judgment.
S104, responding to a change instruction for changing the entity link diagram, and adjusting the link relation between each entity node in the entity link diagram according to the change operation indicated by the change instruction to obtain an adjusted entity link diagram.
In the step, in response to a received change instruction for changing the entity link diagram, according to a change operation indicated by the change instruction, the connection relationship between each entity node in the entity link diagram is adjusted, so that a query mode of 'searching and improving' is realized. Here, "search and improvement" means that, in the process of data query by a user, calibration optimization can be performed on the query result, the optimized query result is recorded, and the optimized query result is used in subsequent applications.
Here, the modification of the query result, that is, the modification of the generated entity link graph, may be a modification that a user perceives according to the user himself, for example, the user may select a corresponding entity node to be modified, and change a connection relationship between the entity nodes; or the client or the server detects the generated entity link diagram, that is, the connection relation between each entity node in the entity link diagram is automatically detected, and if the connection relation is found to have a problem, a change instruction is automatically generated.
In this way, the entity linking result of the data can be continuously optimized according to the use of the user, and no additional manpower and time investment is needed.
Further, when the modification operation includes a merge operation, step S104 includes: in response to the change instruction, determining at least two fusion nodes to be merged from the entity nodes in the entity link graph; taking any one to-be-merged fusion node of the at least two to-be-merged fusion nodes as a master fusion node, and taking other to-be-merged fusion nodes except the master fusion node of the at least two to-be-merged fusion nodes as slave fusion nodes; for each slave fusion node, connecting at least one original node to be merged with a link between the slave fusion nodes to the master fusion node; and deleting the slave fusion nodes to obtain the adjusted entity link graph.
In the step, in response to a change instruction, at least two fusion nodes to be merged are determined from entity nodes in a generated entity link graph, and any one of the two fusion nodes to be merged is taken as a main fusion node and is at least used; and taking the other fusion nodes to be merged except the main fusion node in the two fusion nodes to be merged as slave fusion nodes.
And aiming at each slave fusion node, connecting at least one original node to be merged, which has a link with the slave fusion node, to the master fusion node, and deleting the slave fusion node to obtain an adjusted entity link graph.
The management method of the entity link relation provided by the embodiment of the application obtains entity information of an entity to be linked, which is input by a user; acquiring a plurality of pieces of description information of the entity to be linked from different databases based on the entity information; generating an entity link graph of the entity to be linked based on the plurality of pieces of description information; responding to a change instruction which is applied to the entity link graph and used for changing the entity link graph, and adjusting the connection relation among all entity nodes in the entity link graph according to change operation indicated by the change instruction to obtain an adjusted entity link graph. Therefore, the generated entity link diagram can be changed, so that the entity link result is continuously optimized along with the use of the user, the accuracy of the search result is improved, and the search time of the user can be saved.
Referring to fig. 2, fig. 2 is a flowchart illustrating another entity link relationship management method according to an embodiment of the present application. As shown in fig. 2, a method for managing an entity link relationship provided in an embodiment of the present application includes:
