Abstract

To address the problems of redundant information, insufficient semantic coverage, and nonstandard expressions in automatic Chinese patent title generation, this study proposes a Multi-Stage Generation and Multi-Dimensional Quality Evaluation method (MG-MQE) . The proposed method first performs key sentence extraction and abstract fusion to filter and condense lengthy patent texts, enhancing the relevance and compactness of input information. It then employs a fine-tuned pre-trained model to generate multiple candidate titles. Subsequently, it introduces a multi-dimensional scoring mechanism combining a discriminative model and linguistic rules to comprehensively evaluate the candidates in terms of semantic quality and linguistic conformity, thereby selecting the optimal title. Experimental results on a self-constructed patent draft–title dataset show that MG-MQE achieves ROUGE-1, ROUGE-2, and ROUGE-L scores of 0.7784, 0.6076, and 0.7465, respectively, significantly outperforming various baseline models. The findings demonstrate that the proposed method effectively improves the quality of automatic patent title generation and provides a feasible approach for intelligent patent document drafting.
