Abstract

The present invention provides a multi-document summary generation system and method based on entity orientation, which relates to the field of natural language processing. The first encoder is used to effectively analyze the model cross-document entity information and analyze the significance of the entity, and the second encoder is constructed in combination with the hierarchical self-attention mechanism to analyze the cross-document relationship. The hierarchical cross-attention mechanism is used to integrate the information of the entity, paragraph, document and token levels into the summary generation, so as to achieve the technical effect of being able to analyze the significant entities in the long text composed of multiple documents, improve the factual fidelity of the summary and reduce the hallucination problem.
