This application discloses an AI-based secure grading
system and method based on scoring points, belonging to the field of computer-aided education technology. The
system includes: a question
bank data interface module, which organizes question
bank data hierarchically, labels each scoring point with a preset
score, and associates the data with exam type identifiers; a
scoring rule configuration layer, which maintains independent scoring meta-rules for each exam type; a scoring prompt word construction module, which establishes a cross-layer index association from the question
bank layer to the configuration layer through exam type identifiers, loads scoring meta-rules, and assembles them into structured prompt words; a concurrent scheduling and secure call module, including
semaphore rate limiting,
exponential backoff retry, and concurrent scheduling; a post-
processing score clamping module, which sequentially executes scoring point-level and total
score clamping, followed by
automatic filtering at multiple confidence levels, without requiring manual intervention throughout the process; and a scoring output module, which outputs the grading results after security
verification. This application adapts to the scoring logic of different exams through cross-layer index association, combined with multi-level security clamping and
fully automatic confidence filtering, to achieve universal AI-based secure grading.
