    description: "Base class for entities detected through automated analysis processes.\n\
      \n**DEFINITION**:\n\nDetectedEntity represents items identified by automated\
      \ analysis pipelines\n(computer vision, NLP, audio analysis, etc.). Each detected\
      \ entity captures:\n- What was detected (via has_type → specific Type\
      \ class)\n- Detection confidence (probability score)\n- Temporal/spatial location\
      \ (timestamps, bounding boxes)\n\n**CRITICAL: DETECTION vs TYPE**\n\n| Aspect\
      \ | DetectedEntity (This Class) | *Type Classes (Categories) |\n|--------|----------------------------|---------------------------|\n\
      | **Nature** | Detection result | Classification |\n| **Examples** | \"Transition\
      \ at 00:03:15\" | FADE_IN, CUT, DISSOLVE |\n| **Properties** | Confidence, timestamps\
      \ | Semantic metadata |\n| **Cardinality** | Many instances per video | ~20-30\
      \ types |\n\n**USE CASE - Video Annotation**:\n\n```\nVideoAnnotation\n  │\n\
      \  └── has_detected → DetectedEntity[]\n        ├── has_type →\
      \ TransitionType (FADE_IN, CUT, etc.)\n        ├── confidence_score → 0.95\n\
      \        ├── start_time → \"00:03:15\"\n        └── end_time → \"00:03:17\"\n\
      ```\n\n**USE CASE - Text Detection**:\n\n```\nVideoAnnotation\n  │\n  └── has_detected\
      \ → DetectedEntity[]\n        ├── has_type → TextType (TITLE, CAPTION,\
      \ etc.)\n        ├── confidence_score → 0.87\n        ├── has_geographic_extent\
      \ → [x1, y1, x2, y2]\n        └── has_label → \"Museum Tour\"\n```\n\n\
      **ONTOLOGY ALIGNMENT**:\n\n- **PROV-O Entity**: Detected entities are generated\
      \ by activities\n- **W3C Web Annotation**: Compatible with annotation body/target\
      \ patterns\n- **CIDOC-CRM E73_Information_Object**: Information derived from\
      \ sources\n\n**RELATIONSHIP TO SLOTS**:\n\n- `has_detected`: Links from\
      \ VideoAnnotation → DetectedEntity[]\n- `has_type`: Links DetectedEntity\
      \ → TransitionType, TextType, etc.\n- Uses shared slots for identifier, label,\
      \ confidence\n"

    comments:
    - Base class for automated detection results
    - Use has_type to link to specific Type classes (TransitionType, TextType)
    - 'Captures detection metadata: confidence (via generated_by), timestamps,
      bounding boxes'
    - Generated by detection activities (prov:wasGeneratedBy pattern)
    - 'Rule 39 compliant: uses has_* slot naming (migrated from has_or_had_*)'
    - 'MIGRATED 2026-01-19: confidence_score → generated_by + ConfidenceScore'
