The invention discloses a knowledge-intensive multi-document question-answering method and product based on multi-agent cooperation, and the method comprises the steps: 1, dynamically generating a multi-dimensional complementary expert role set based on the multi-view agent cooperation of roles, forming a candidate strategy set based on all expert roles, and selecting an optimal strategy for integrating knowledge through a voting mechanism; 2, constructing a closed-loop process of refinement of the reflection knowledge, extracting atomic facts through a sliding window and an reflection construction mechanism, and performing a recursive process of task
decomposition and knowledge
distillation to obtain essence knowledge; 3, based on the optimal strategy in the step 1 and the essence knowledge obtained in the step 2, cross-document comprehensive reasoning is achieved, and a final answer is generated. According to the method, the limitation of a single role
view angle is broken through, a high-quality knowledge basis is provided for subsequent reasoning, different types of knowledge-intensive cross-document tasks can be flexibly handled, dispersed and multi-source information is efficiently processed, and the method has wide application prospects and market value.
