Entity knowledge automatic extraction method, computer device and computer readable medium

Abstract

The invention provides an automatic entity knowledge extraction method, a computer device and a computer readable medium. The entity knowledge automatic extraction method comprises the steps that an input text H0 is input into the first K layers of a BERT model composed of N layers to be processed, and a context representation vector HK is output in the Kth layer; the HK is input into the remaining N-K layers of the BERT model for the first time due to a first task to be processed, at the moment when a context representation vector is output on the Nth layer, each layer of the remaining N-K layers processes input on the basis of a first mask matrix, and a first layer entity is obtained on the basis of first layer entity recognition; and inputting the HK into the residual N-K layers of the BERT model again for processing due to a second task, processing the input of each layer of the residual N-K layers on the basis of a second mask matrix at the moment when the context representation vector is output at the Nth layer, and performing second layer entity identification to obtain a second layer entity. Therefore, the feature extraction capability of the BERT model on the entity knowledge can be improved.

Description

Technical field [0001] The present invention relates to the field of text processing, and more particularly to an entity knowledge automatic extraction method and a computer device, a computer readable medium. Background technique [0002] As an important task in natural language processing, information extraction is a text processing technology for extracting meaningful entities, attributes, relationships, events such as original unstructured natural language text. In official document writing, its physical knowledge has an important role, can assist official writing, such as content review. The current entity knowledge automatic extraction method still has a low accuracy and difficulty optimization. Therefore, it is necessary to propose an improved entity knowledge automatic extraction method. Inventive content [0003] It is an object of the present invention to provide an entity knowledge automatic extraction method and a computer device, a computer readable medium, which ca...
