Embodiment Construction

[0067] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0068] figure 1 It is a flow chart of the method for solving the entity alignment problem in the knowledge map of the present invention. The method of this embodiment can be executed by the device for solving the entity alignment problem in the knowledge map, which can be implemented by software and integrated into the terminal device (for example, a notebook) where the search engine client (such as 360 search, etc.) is located. , pad, mobile phone, etc.).

[0069] When constructing or updating a knowledge graph, in the process of data fusion, it is necessary to solve the problem of entity alignment, that is, to judge whether different entities actually describe the same thing. Such as figure 1 As shown, the present invention provides a method for solving the entity alignment problem in the knowledge map, the method comprising:

Abstract

The invention provides a mapping Knowledge Domain entity alignment problem solving method and device; the method comprises the following steps: comparing two or more entities of same specific names with multi senses in the encyclopedia; determining whether the two or more entities of same specific names belong to the same entity or not. The method and device can effectively solve the entity alignment problems in the existing artificial solving mode, thus saving cost, and greatly improving efficiency.

Description

technical field [0001] The present invention relates to the technical field of communication networks, in particular to a method and device for solving the problem of entity alignment in knowledge graphs. Background technique [0002] With the rapid development of the Internet, in order to obtain information and learn knowledge more conveniently and clearly, search engine services are more frequently used for information search and query. In the field of knowledge graphs, we are faced with the problem of entity alignment. The so-called entity alignment refers to how to determine whether the entities (concepts) extracted from different web pages are the same. "Entity" can be a thing in reality, or a concept, and so on. For example, a company is an entity, and a term is also an entity. When data obtained from different channels are adjusted and updated, because different data describe the same thing in different ways, or for the same thing, different data sources describe i...
