Scenario CaseFull-media Knowledge Base
Unified retrieval for text, image, audio, and video
Different media require different parsing paths, but the results need one retrievable, traceable, evaluable knowledge layer.
Decision Boundaries
- Batch small archives; use queues for constant media inflow.
- Prefer local inference for sensitive material.
- Keep source, timestamp, and original location.
Text parsing
Preserve headings, paragraphs, tables, and document structure.
Image understanding
Generate descriptions, tags, and classifications.
Audio/video processing
Transcribe audio and combine keyframes with subtitles.
Unified retrieval
Text queries can hit documents, images, videos, and transcripts.
