Experiment on Small Heterogeneous Datasources

This experiments are made following this details.

Methods Comparison

Total time

It is the total query answering time.

The materialization (MATREF) takes 2min6s (126 082ms) to compute and contains 2 049 385 triples. The saturated materialization (MATSAT) takes 4min35s (275 126ms) to compute and contains 3 395 853 triples.

Rewritings Processing Time

Rewritings processing is the part of query answering that concerns only rewriting building and rewriting optimization. It doesn't includes the query plan optimization and evaluation.

rewriting-processing-time.png

Query Plan Processing Time

Query plan processing time are the sum of query plan optimization and query plan evaluation. Since the two method returns minimal equivalent rewriting set, we expect that there is no time different between the two method at this step.
