Problems solved by technology

[0003] However, there are still various problems and deficiencies in these traditional solutions for extracting entity-related information. In many cases, the performance requirements for extracting entity-related information cannot be met, which leads to poor user experience in applications such as entity recommendation.

Embodiment Construction

[0017] The principle and spirit of the present disclosure will be described below with reference to several exemplary embodiments shown in the accompanying drawings. It should be understood that these specific embodiments are described only to enable those skilled in the art to better understand and realize the present disclosure, rather than to limit the scope of the present disclosure in any way.

[0018] As mentioned above, traditional entity relationship extraction methods mainly include pure open extraction methods and structured extraction methods. However, there are some problems and deficiencies in these two traditional extraction methods. For example, the purely open extraction method is mainly used to process batch extraction of knowledge, but the extraction delay for new entities and new knowledge is relatively long, and the update time is long, so it cannot solve the problem of time-sensitive knowledge update. On the other hand, the main disadvantage of the struct...

Abstract

The embodiment of the invention provides a method and a device for extracting entity related information, an electronic device and a computer readable storage medium. In the method, a computing deviceobtains a plurality of candidate texts associated with a predetermined entity and a predetermined attribute. Further, the computing device determines at least one target text from the plurality of candidate texts based on semantics of an entity attribute pair formed by the predetermined entity and the predetermined attribute. Further, the computing device determines an attribute value of a predetermined attribute of the predetermined entity based on the at least one target text. According to the embodiment of the invention, the timeliness can be improved and the labor cost can be reduced whenthe entity related information is extracted.

Description

technical field [0001] Embodiments of the present disclosure generally relate to the technical field of information processing, and more particularly, relate to a method, device, electronic device, and computer-readable storage medium for extracting entity-related information. Background technique [0002] Traditionally, there are two ways to extract information about entities. One way is purely open extraction, which mainly includes open extraction for free text and semi-structured web pages. That is to say, in the free text and semi-structured webpages of the Internet, openly mine the relevant semantic relations between entities and entities, where semi-structured webpages refer to webpages with a certain structure, and this structural representation is based on hypertext Text Markup Language (HTML). For example, in the text "Yao Ming, born in Xuhui District, Shanghai on September 12, 1980", directly excavate (Yao Ming, date of birth, September 12, 1980) and (Yao Ming, p...
