Statement Predicates
Evaluation methods for determining semantic relationships between predicates used in FCP statements.
Fide-OwlEquivalentProperty-StatementPredicate-v1
Determine whether two predicates used in FCP statements are semantically equivalent across vocabularies.
Are https://schema.org/worksFor and https://dbpedia.org/ontology/employer interchangeable when used as statement predicates? This method evaluates owl:equivalentProperty claims between predicate Fide IDs.
Fide-OwlEquivalentProperty-StatementPredicate-v1:Subject
The statement claim being evaluated. Raw identifiers must be full IRIs for all statement parts.
The Object is always the primary predicate you want to resolve to; the Subject is the predicate requiring alignment.
| Statement Part | Raw Identifier | Fide ID |
|---|---|---|
| Subject | https://dbpedia.org/ontology/employer | did:fide:0x65 |
| Predicate | http://www.w3.org/2002/07/owl#equivalentProperty | did:fide:0x65 |
| Object | https://schema.org/worksFor | did:fide:0x65 |
Evaluation
The evaluation statement structure.
| Statement Part | Raw Identifier | Fide ID |
|---|---|---|
| Subject | Statement: Fide-OwlEquivalentProperty-StatementPredicate-v1:Subject | did:fide:0x60 |
| Predicate | Fide-OwlEquivalentProperty-StatementPredicate-v1 EvaluationMethod (e.g., GitHub spec link) | did:fide:0xe5 |
| Object | Verdict: -1, 0, or 1 | did:fide:0x66 |
Evaluation Criteria
| Verdict | Meaning | Criteria |
|---|---|---|
1 | Equivalent | The predicates are interchangeable in all normal use cases. Authoritative sources (Schema.org, DBpedia, W3C specs) document the alignment. |
0 | Uncertain | The equivalence is domain-dependent or context-specific. Edge cases exist where the predicates diverge. |
-1 | Not Equivalent | The predicates have fundamentally different semantics, different domains, or different ranges. |
Fide-OwlInverseOf-StatementPredicate-v1
Determine whether two predicates used in FCP statements describe the same relationship from opposite directions.
Are https://schema.org/worksFor and https://schema.org/employee inverses? If Alice worksFor ACME, then ACME employee Alice — the same semantic fact, expressed from different sides.
Fide-OwlInverseOf-StatementPredicate-v1:Subject
The statement claim being evaluated. Raw identifiers must be full IRIs for all statement parts.
The Object is always the primary predicate you want to use as the reference direction; the Subject is the inverse predicate requiring alignment.
| Statement Part | Raw Identifier | Fide ID |
|---|---|---|
| Subject | https://schema.org/employee | did:fide:0x65 |
| Predicate | http://www.w3.org/2002/07/owl#inverseOf | did:fide:0x65 |
| Object | https://schema.org/worksFor | did:fide:0x65 |
Evaluation
The evaluation statement structure.
| Statement Part | Raw Identifier | Fide ID |
|---|---|---|
| Subject | Statement: Fide-OwlInverseOf-StatementPredicate-v1:Subject | did:fide:0x60 |
| Predicate | Fide-OwlInverseOf-StatementPredicate-v1 EvaluationMethod (e.g., GitHub spec link) | did:fide:0xe5 |
| Object | Verdict: -1, 0, or 1 | did:fide:0x66 |
Evaluation Criteria
| Verdict | Meaning | Criteria |
|---|---|---|
1 | Inverse | The predicates describe the same relationship with subject and object swapped. Authoritative sources document this inverse relationship. |
0 | Uncertain | The inverse relationship is partial or domain-dependent. |
-1 | Not Inverse | The predicates are unrelated or describe fundamentally different relationships. |
