摘要

•Graph summarization overcomes negative impact of RDF graphs’ size on query processing•Grouping (GBS) and Query (QBS) Graph Summarization create compact RDF representations•GBS reduces RDF graph sizes but may not ensure query answer completeness•QBS generates lossless RDF representations while preserving query answer completeness•Experimental studies on real-world RDF graphs suggest QBS speeds up query processing
