UnverifiedKnowledge base retrieval finds the most relevant document fragments by computing the cosine similarity between the query vector and document vectors, then passes them to a large model to generate an answer.77% similarUnverifiedThe knowledge generalization mechanism enables Procedural Graphs to identify common patterns across tasks and reuse optimized graph structure fragments to achieve knowledge transfer.74% similarUnverifiedReranking models score the query and document together, capturing finer-grained relevance signals, but inference must be run in real time at query time, resulting in higher latency.72% similarUnverifiedThe ordering of the system should reflect the change frequency of each part, a principle that applies to prompt caching and to any optimization mechanism based on prefix matching.72% similarUnverifiedThe ontology layer has an advantage in reasoning explainability over pure vector retrieval, as the system can derive conclusions step by step along semantic relationship chains with each step traceable.71% similar
