- Removed obsolete slots: `has_or_had_custodian_observation`, `provider`, and `specificity_annotation`. - Updated `has_or_had_score` slot to use `SpecificityScore` class and modified its description and examples. - Added new slots: `end_seconds`, `end_time`, `has_archive_path`, `has_or_had_custodian_name`, `protocol_name`, and `protocol_version`. - Introduced a script `check_annotation_types.py` to validate the presence and structure of `custodian_types` in YAML files. - Added a script `update_specificity.py` to automate updates related to `SpecificityAnnotation` to `SpecificityScore`.

description: '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.
