Abstract

The invention discloses a text language association relationship labeling method and device. The close relevance of each information extraction subtask of the text language is utilized; a composite labeling method independent of a specific model is designed; a plurality of text language information extraction tasks can be naturally fused; joint learning and integrated training of multiple text language association tasks are achieved, for example, joint learning supporting named entity recognition and named entity standardization, joint learning supporting named entity recognition and entity relationship extraction, joint learning supporting named entity recognition and entity disambiguation and the like. According to the text language association relationship composite labeling method provided by the invention, the close association among the sub-tasks of text language information extraction is fully utilized, and complete joint learning is realized, so that information sharing among the associated tasks can be mutually promoted, and the accuracy and recall rate of text language information extraction are improved on the whole.

Description

technical field [0001] The invention belongs to the field of information technology, and relates to information extraction of text language assisted by computer intelligence technology. Specifically, it involves the use of the close relevance of the sub-tasks of text language information extraction, designing a composite labeling method to naturally integrate multiple text language information extraction tasks, and realizing joint learning and integrated training of multiple text language related tasks. It enables information sharing and mutual promotion between related tasks, and improves the accuracy and recall rate of text language information extraction. Background technique [0002] As the main form of expression of natural language, text language is an important carrier of information. In today's era of information explosion, how to extract useful structured information from massive unstructured texts is the key to data intelligence. Information extraction in text la...
