Looks at Sesame, Jena, and Allegro in working with large datasets

Primarily LUBM datasets, mentions University Ontology Benchmark

Metrics: Load time, repository size, response time

  • Cumulative load time: How long to long data and ontologies (hours!)
  • Query response time: Mean of execution time over four identical queries
  • Completeness: Complete iff returns all correct responses
  • Soundness: Sound iff only returns correct responses
  • Disk-Space usage: Amount of disk space used to load data and ontologies

Multiple styles of query used

  • Low volume, low complexity (Lehigh query 1)
  • High volume, low complexity (Lehigh query 2)
  • High complexity (Lehigh query 9)
  • High volume: Large portion of data returned in result set
  • Complexity: Substantial processing time required

Queries manually ported for different input languages
