Figure 2. Workflow of the Autonomous Knowledge Update Loop. (A) A Schedule Trigger (e.g., daily at 4:00 AM) initiates the loop; (B) Multi-source Data Ingestion collects heterogeneous data from various sources; (C) AI Validation & Processing performs pre-screening, cleaning, and formatting. Feedback from this stage is used to refine the data-processing workflow, ensuring increasingly reliable updates; (D) The curated data is embedded and indexed into the KAG Knowledge Base, completing the cycle and supporting continuous knowledge updates.
