Problems solved by technology

[0003] Traditional information retrieval methods can only provide users with keyword search results. These search results are mostly flat document views, which do not dig out the entities in the information and the relationships between them, let alone display them intuitively. this relationship

Embodiment Construction

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0040] Such as figure 1 As shown, the embodiment of the present invention provides a method for constructing an entity relationship graph, and the method may include the following steps:

[0041] Step 101: configure multiple entities with related relationships in the same entity list; and configure related relationships of multiple entities in the same entity list in the relationship list.

[0042] Step 102: Obtain keywords input by the user.

Abstract

The invention provides an entity relation graph construction method and device. The method includes the steps that an entity list and a relation list are configured; a keyword input by a user is obtained; according to the keyword, a target entity list and a target relation list which correspond to the keyword are searched for; each target entity in all target entities included in the target entity list is abstracted into Json entity data, and the relation between two related target entities in the target relation list is abstracted into Json relation data; according to the abstracted Json entity data and the abstracted Json relation data, a target entity relation graph is constructed, wherein the constructed target entity relation graph includes all the target entities and the relations in all the target entities. According to the scheme, the entity relation graph can be constructed vividly, and the relations between the entities can be obviously displayed according to the entity relation graph.

Description

technical field [0001] The invention relates to the technical field of information retrieval, in particular to a method and device for constructing entity relationship graphs. Background technique [0002] With the continuous development of information technology, there are many types of entities in the tax industry, and the relationship between entities is intricate. When it is necessary to retrieve the relationship between entities, the current information retrieval method is to input a keyword so that the retrieval tool returns all documents related to the keyword according to the keyword. [0003] Traditional information retrieval methods can only provide users with keyword search results. These search results are mostly flat document views, which do not dig out the entities in the information and the relationships between them, let alone display them intuitively. this relationship. [0004] Therefore, it is necessary to provide a graph construction method capable of s...
