| # ConceptNet |
|
|
| Commonsense relation prediction tasks derived from ConceptNet 5.7 (English subset), encoded as ILP problems. Each task targets one ConceptNet relation type; the background knowledge provides the other nine relations restricted to the same entity set, enabling reasoning across relation types. |
|
|
| Entities are filtered to those appearing in at least 3 triples; each relation is capped at 2000 positive examples. Negatives are sampled from the cross-product of entities appearing in background knowledge. |
|
|
| **Tasks:** 10 (`r001_at_location` through `r010_used_for`) |
|
|
| | Task | Relation | Description | |
| |------|----------|-------------| |
| | `r001_at_location` | `AtLocation` | Typical location where a concept can be found | |
| | `r002_capable_of` | `CapableOf` | Actions a concept is capable of performing | |
| | `r003_causes` | `Causes` | Events or states that a concept causes | |
| | `r004_has_a` | `HasA` | Things a concept possesses or contains | |
| | `r005_has_prerequisite` | `HasPrerequisite` | Prerequisites required before an action | |
| | `r006_has_property` | `HasProperty` | Properties or attributes of a concept | |
| | `r007_is_a` | `IsA` | Hypernym or category membership | |
| | `r008_part_of` | `PartOf` | Meronymy: concept is part of a larger entity | |
| | `r009_receives_action` | `ReceivesAction` | Actions that can be done to a concept | |
| | `r010_used_for` | `UsedFor` | Purpose or function of a concept | |
|
|
| **Head relation:** `f(Concept1, Concept2)` — the target ConceptNet relation holds between `Concept1` and `Concept2`. |
|
|
| **Background relations:** For each task, the other nine ConceptNet relations serve as background. Each is a binary relation over concepts: |
|
|
| | Relation | Arity | Description | |
| |----------|-------|-------------| |
| | `at_location(C1, C2)` | 2 | `C1` is typically found at location `C2` | |
| | `capable_of(C1, C2)` | 2 | `C1` is capable of `C2` | |
| | `causes(C1, C2)` | 2 | `C1` causes `C2` | |
| | `has_a(C1, C2)` | 2 | `C1` has `C2` | |
| | `has_prerequisite(C1, C2)` | 2 | `C1` has prerequisite `C2` | |
| | `has_property(C1, C2)` | 2 | `C1` has property `C2` | |
| | `is_a(C1, C2)` | 2 | `C1` is a kind of `C2` | |
| | `part_of(C1, C2)` | 2 | `C1` is part of `C2` | |
| | `receives_action(C1, C2)` | 2 | `C1` receives action `C2` | |
| | `used_for(C1, C2)` | 2 | `C1` is used for `C2` | |
|
|
| (The relation being predicted is excluded from the background for that task.) |
