This invention discloses an automatic roadmap construction method for engineering problem solving based on a large language model. The invention constructs a skill point repository dataset and an expert-verified roadmap dataset. An automatic roadmap construction model is built based on these datasets. A pre-defined complex engineering problem is input into the automatic roadmap construction model. An initialization agent generates an initial roadmap. A knowledge agent enhances the initial roadmap by combining internal and external knowledge. A logical critique agent and a granular critique agent critique the logical structure and task node decomposition granularity of the roadmap, respectively. A revision agent improves the roadmap based on the critique results. The improved roadmap is evaluated, and if it reaches a preset passing score, a structured roadmap for solving the complex engineering problem is output. This invention effectively addresses the shortcomings of existing technologies in cultivating the ability to solve complex engineering problems.

This invention relates to the fields of artificial intelligence and natural language processing technology, and discloses a question-answering method and system for tunnel surrounding rock that integrates knowledge graphs and semantic retrieval. It aims to solve the problems of missing logical connections, insufficient authority, and semantic bias in existing methods. The solution mainly includes: constructing an industry-standard question-answering pair dataset, a vector index library, and a knowledge graph entity library; receiving user queries and extracting key entities and intent tags; performing a three-hop neighborhood traversal to generate a structured logical chain, and simultaneously performing semantic similarity retrieval to recall semantically relevant text fragments; using the structured logical chain to perform background completion and conflict verification on the recalled fragments, and fusing the processed fragments with the structured logical chain to form a fused evidence chain; applying compliance constraints to the fused evidence chain to generate the final answer. This invention achieves deep logical reconstruction and accurate semantic matching, effectively suppressing knowledge illusions, and is particularly suitable for tunnel surrounding rock engineering design.
