measurementThe IKEDS framework evaluation utilized a financial investment dataset comprising 47 decision scenarios derived from historical market data spanning 2015 to 2023, including asset allocation, M&A analyses, and ESG investment screening.

claimThe IKEDS framework shows stronger performance advantages for governance assessment scenarios compared to environmental impact evaluation scenarios, as governance assessment tends to be more structured and rule-based.

referenceThe RAG-Only baseline system used in the IKEDS framework evaluation utilizes identical retrieval and generation components to the IKEDS framework but treats all knowledge as unstructured text without structured knowledge representation.

claimThe IKEDS framework evaluation assessed knowledge relevance, explanation quality (comprehensibility, completeness, and traceability), cross-domain integration, and adaptability (learning efficiency and knowledge transfer).

measurementThe IKEDS framework evaluation utilized a healthcare management dataset comprising 53 scenarios based on anonymized operational data from three healthcare organizations, covering resource allocation, clinical pathway selection, and quality improvement initiatives.

claimThe IKEDS framework evaluation methodology ensured that all baseline systems (KG-Only, RAG-Only, and Parallel-KG-RAG) had access to identical knowledge sources and computational resources to ensure observed performance differences reflected architectural advantages rather than disparities in underlying data or resources.

claimThe IKEDS framework's efficiency advantage stems from its ability to leverage structured knowledge to guide learning, which reduces the need for extensive examples.
