  1. Performance analysis of three semantic web prototype applications:GORouter, AllegroGraph and YeastHub. In this table, the AllegroGraph project used the disk approach to query "LUBM50, Lehigh U. Benchmark" datasets (about 6.88 million triples). The retrieval speed is about 0.04 million triples per second. The YeastHub project uses the main memory approach to query the UniProt data file (about 1.4 million triples).
