KNOWPLAN is a knowledge-driven AI system for smart degree pathway planning. It consists of two stages: curriculum reconstruction and degree path optimization. The curriculum reconstruction stage uses CatalogBrowse to extract information from university catalogs, departmental pages, JSON endpoints, and PDFs, using deterministic parsing and finite atomic catalog obligations to build a curriculum graph. The degree path optimization stage uses DegreeMap, which consumes the output of CatalogBrowse, compiles it into a typed requirement hypergraph, and optimizes personalized utility and option value using CP-SAT. Experimental results show that KNOWPLAN achieves 96.2% inventory recall and 88.7% masked-source recovery at 47% less source access than an exhaustive crawler. Blogger's Review: KNOWPLAN is an innovative AI system that uses knowledge-driven methods to optimize degree planning, with high practical value and broad application prospects.
