Bossam’s Performance over LUBM

January 24, 2007 Leave a comment Go to comments

Recently, a big performance-wise improvement was injected into Bossam. 😉 I performed a preliminary LUBM benchmark with Bossam and got a promising results. The machine was a notebook with a fast Intel Core Duo 1.8Ghz processor and 2 GB of RAM. I assigned 256MB heap memory for the Java machine (JDK 1.3.1) for the test. The test was done on two data sets: one with about 50,000 triples and another with 100,000 triples. As Bossam is the forward-chaining engine, it took a while to finish the full derivation phase. It took about 100 seconds for 100,000 triples and 22 seconds for 50,000 triples. The following chart shows the elapsed time for 13 LUBM queries. Answers were correct. I think the performance figure shown in the chart is not bad for a rule-based OWL reasoner. 🙂
