Sofos: Demonstrating the Challenges of Materialized View Selection on Knowledge Graphs
Summary: Demonstrates materialized view selection challenges for RDF/SPARQL by adapting relational cost models to the RDF graph model and proposing new RDF-specific models. Sofos compares these models on real RDF analytics, revealing pitfalls, tradeoffs in time, memory, and query characteristics. (summarized by gpt-5-nano on Feb 09 2026)
