基于大语言模型的灌浆工程知识服务系统
Grouting works knowledge service system based on large language model
摘要
Abstract
Professional information acquisition in grouting engineering currently relies on manual processing of di-verse texts,resulting in high labor costs and low efficiency.To address these challenges,it is essential to develop a knowledge service system based on large language model.The construction of this service system hinges on provi-ding high-quality text for fine-tuning large language model and managing the inherent timeliness and information security risks of specific engineering texts.To overcome these challenges,a hybrid strategy dataset construction method is proposed,based on universal grouting construction specifications.By incorporating self-checking chain of thought and scoring strategies,the quality limitations of traditional data generation are addressed,ensuring the provision of high-quality data necessary for fine-tuning the large language model.Additionally,LangChain is em-ployed to build a retrieval augmented generation framework for grouting engineering.By incorporating an embedded local knowledge base,this framework ensures the isolation of specific grouting text and models,guaranteeing infor-mation security.To meet the timeliness requirements of specific engineering texts,a staged update approach is a-dopted.Professional tests demonstrate that the Qwen-7B-Grout model,fine-tuned using our proposed methods,achieves 100％accuracy in the judgment of grouting-specific issues and 80％accuracy in fill-in-the-blank ques-tions.The knowledge service system based on large language model proposed in this study not only facilitates gener-al grouting knowledge Q&A but also realizes efficient retrieval augmented generation of engineering documents.In conclusion,this system significantly improves production efficiency and reduces labor costs,offering new intelligent assistance for grouting design and construction management.关键词
