| Property | Range | Description |
|---|---|---|
| affectsConcept inherited | Concept | Links a semantic change event to the term/concept undergoing change. |
| controlledForArtifacts inherited | boolean | Boolean: whether detection method controlled for frequency/polysemy artifacts. |
| evidencedBy inherited | disposition | Links semantic change event to documentary evidence supporting its identification. |
| hasCause inherited | — | Links semantic change to its driving cause (external or internal). |
| hasConfidence inherited | float | Researcher's confidence in the semantic change annotation (0.0-1.0). |
| hasControlCondition inherited | — | Reference to control/null condition for validating genuine vs. artifact change. |
| hasDescription inherited | string | Human-readable description of the semantic change event. |
| hasEndYear inherited | integer | Calendar year when semantic change completed or stabilized (for query convenience). |
| hasExecutionTrace inherited | Activity | Retrospective provenance: WHAT was actually detected. |
| hasFromMeaning inherited | Concept | The original or source meaning before the semantic change. |
| hasProcessSpecification inherited | Plan | Prospective provenance: HOW change should be detected. |
| hasSentimentDirection inherited | string | Direction of sentiment change: pejoration, amelioration, or neutral. |
| hasStartYear inherited | integer | Calendar year when semantic change began (for query convenience). |
| hasTemporalScale inherited | string | Scale of temporal span: centuries, decades, years, months. |
| hasTextualEvidence inherited | — | Links to specific text segment providing evidence for semantic change. |
| hasToMeaning inherited | Concept | The new or target meaning after the semantic change. |
| hasURIStability inherited | float | Measure of identifier consistency (0.0-1.0); 1.0 = no URI changes. |
| hasWorkflowStructure inherited | Plan | Links semantic change detection to process design (prospective provenance). |
| isSynthetic inherited | boolean | Boolean: whether this is synthetic (simulated) or authentic (real) semantic change. |
| occursDuringInterval inherited | Interval | Links semantic change event to the temporal interval when it occurred. |
| occursInDomain inherited | Concept | The disciplinary or discourse domain where semantic change occurs. |
| passesControlTest inherited | boolean | Boolean: whether change observed in genuine but not control condition. |
| usesDetectionMethod inherited | DetectionMethod | The computational method used to detect/measure this semantic change. |
| usesExternalKnowledgeBase inherited | — | External knowledge source consulted for semantic correspondence. |
