Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some, not all, embodiments of the application.

[0029] In the traditional open-domain knowledge extraction methods, the extraction results are limited to the extracted text itself, and the implicit attribute relationship cannot be extracted. For example, if the text to be processed is "a certain A and a certain B have a daughter", the existing knowledge extraction methods cannot extract the implicit attribute relationship that "a certain A" and "a certain B" are husband and wife. In order to solve the hidden problems of knowledge extraction, the text generation method can be used for open domain knowledge extraction. However, this method is prone to many problems such as extraction errors and out-of-the-box problems, which leads to low extracti...

Abstract

The invention discloses a text data processing method and device, a storage medium and electronic equipment. The text data processing method comprises the steps of performing knowledge generation on a to-be-processed text to obtain a first candidate knowledge set; performing knowledge extraction on the to-be-processed text to obtain a second candidate knowledge set; and performing knowledge screening on the first candidate knowledge set and the second candidate knowledge set to obtain an extracted knowledge set. According to the invention, the accuracy of open domain knowledge extraction is improved.

Description

technical field [0001] The present application relates to the technical field of natural language processing, in particular to text data processing methods and devices, storage media and electronic equipment. Background technique [0002] Knowledge extraction refers to the extraction of data from different sources (including structured data and unstructured data) to form a knowledge set (structured data). Knowledge extraction can be divided into limited domain knowledge extraction and open domain knowledge extraction. However, some existing knowledge extraction methods have the problem of low accuracy. Contents of the invention [0003] In view of this, the present application provides a text data processing method and device, a storage medium and electronic equipment, so as to improve the accuracy of knowledge extraction. [0004] In the first aspect, a text data processing method is provided, and the text data processing method includes: performing knowledge generation...
