Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| Use cardinality-minimal explanations instead of inclusion-minimal explanations | Explanation problems for OMQA under existential rules · GF existential rules, data complexity | IS-MINEX complexity | Hurt |
| Use weight-minimal explanations instead of cardinality-minimal explanations | MINEX-REL, MINEX-IRREL, and MINEX-NEC · Existential-rule languages studied | computational complexity | Hurt |
| Use cardinality-minimal explanations instead of weight-minimal explanations | IS-MINEX and ALL-MINEX · Existential-rule languages studied | computational complexity | No clear effect |
| Add fact weights to express differing penalties | Preferred explanations for OMQA · Weight-minimal explanations | route preference: 14 | Helped |
