- Migrated `audio_event_segments` to `has_or_had_segment` with range `AudioEventSegment` in VideoAudioAnnotation.yaml. - Removed deprecated slots: `approved_by`, `audio_event_segments`, `bay_number`, `box_number`, and `budget_status`. - Created new classes: `AudioEventSegment`, `BayNumber`, `BoxNumber`, and `BudgetStatus` to encapsulate previously slot-based data. - Introduced `has_or_had_auxiliary_entities` slot to replace `auxiliary_places` and `auxiliary_platforms`. - Archived removed slots to maintain historical context. - Updated LinkMLViewerPage to utilize new schema element popup for better navigation.

|
description: |
|
|
A temporal segment of audio containing a detected audio event (speech, music, silence, etc.).
|
|
|
|
MIGRATED from audio_event_segments slot (Rule 53).
|
|
Uses generic has_or_had_segment slot with range narrowed to AudioEventSegment.

|
|
A temporal segment of audio containing a detected audio event.
|
|
|
|
**DEFINITION**:
|
|
|
|
AudioEventSegment represents a bounded temporal portion of audio content
|
|
where a specific type of audio event has been detected. This includes:
|
|
- Speech segments (with optional speaker/language info)
|
|
- Music segments (with optional genre/type info)
|
|
- Silence segments (gaps between audio)
|
|
- Sound event segments (applause, laughter, ambient sounds)
|
|
- Noise segments (for quality assessment)
|
|
|
|
**RELATIONSHIP TO VideoTimeSegment**:
|
|
|
|
AudioEventSegment is a specialized sibling of VideoTimeSegment:
|
|
- Both extend CIDOC-CRM E52_Time-Span concept
|
|
- VideoTimeSegment: general video temporal segments
|
|
- AudioEventSegment: audio-specific event segments
|
|
|
|
**AUDIO EVENT TYPES**:
|
|
|
|
| Event Type | Description | Example |
|
|
|------------|-------------|---------|
|
|
| SPEECH | Human speech detected | Interview segment |
|
|
| MUSIC | Music detected | Background soundtrack |
|
|
| SILENCE | Very low or no audio | Gap between segments |
|
|
| SOUND_EVENT | Non-speech/music sounds | Applause, footsteps |
|
|
| NOISE | Noise/interference | Quality issue marker |
|
|
| MIXED | Multiple event types | Overlapping audio |
|
|
|
|
**HERITAGE USE CASES**:
|
|
|
|
| Content Type | Application |
|
|
|--------------|-------------|
|
|
| Oral histories | Speech segment identification |
|
|
| Virtual tours | Background music detection |
|
|
| Lecture recordings | Audience reaction segments |
|
|
| Conservation videos | Narration vs ambient sound |
|
|
| Archival footage | Audio quality assessment |
|
|
|
|
**PROVENANCE**:
|
|
|
|
Created as part of slot migration (Rule 53) from deprecated
|
|
`audio_event_segments` slot to generic `has_or_had_segment` pattern.

comments:
|
|
- Audio event segment for speech, music, silence, sound event detection
|
|
- Temporal boundaries with start/end seconds (primary) and ISO 8601 (secondary)
|
|
- Confidence scoring for AI-generated detections
|
|
- Part of Rule 53 slot migration from audio_event_segments
