AI Technical Summary

Technical Problem

Existing technologies face difficulties in completing long-tail entities in natural resource knowledge graphs. The fine-tuning process is time-consuming and complex, resulting in poor knowledge graph completion effects.

Method used

A natural resource graph completion method based on a large model is adopted, which combines the reasoning ability of a large language model with the structured information of the natural resource knowledge graph. Through knowledge hints and structural prefix adapter processing, the completion ability of long-tail entities is improved and the consumption of fine-tuning resources is reduced.

Benefits of technology

It significantly improves the ability to complete long-tail entities and the reasoning accuracy of complex natural resource relationships, increases the efficiency of knowledge graph completion, enhances the adaptability to diverse natural resource scenarios, and reduces fine-tuning costs.

Abstract

本发明提出一种基于大模型的自然资源图谱补全方法,涉及自然资源的技术领域,首先输入查询三元组,根据所述查询三元组在自然资源知识图谱中进行检索,得到有序的候选实体;其次对所述查询三元组进行知识提示处理,得到提示文本;并提取所述自然资源知识图谱的结构信息,对所述结构信息进行知识前缀适配器处理,得到虚拟知识标记;最后将所述虚拟知识标记和所述提示文本作为输入提示,利用预设的大语言模型对所述候选实体进行重新排序,生成用于对自然资源知识图谱补全的回复内容。本发明有效增强了对长尾实体补全能力,减少了微调的资源消耗,提升知识图谱补全效果。
