Knowledge systems
Search, knowledge graphs and RAG: how to compare approaches using questions, sources and explicit limitations.
RSSWhere to start
Begin with questions people need to answer, then identify the documents or relationships that support each answer. This category compares representations of knowledge without assuming that one database fits every task. Keep relevant text distinct from sufficient evidence. Evaluate source freshness, access permissions and the ability to say that the answer is unknown. Use the same questions to compare an ordinary search baseline, semantic retrieval and explicit relationships. The linked AI and reliability guides connect these choices to task acceptance and maintainability.
