THE STANDARD / 03
Label standard
A shared, machine-readable label keeps origin disclosures consistent across independent blogs.
PGC
Professional content
Requires a separate application and approval before use. Detailed eligibility criteria are set in the alliance policy.
UGC
User content
A content category declared by the author under the alliance standard.
AIGC
L0 — L4
Five levels are declared per article. Formal level definitions await alliance approval; the system supports configurable policy.
Add a marker to every article page
Replace UGC below with the relevant category. An RSS category such as ketrust:UGC also works; the article page takes priority.
<meta name="ketrust:label" content="UGC">Or use a visible element:
<span data-ketrust-label="AIGC-L2">AIGC L2</span>Labels are public disclosures. The platform polls RSS and checks article pages.
What happens after labeling?
- We poll the RSS feeds of verified blogs for new and updated posts.
- Missing labels appear in the dashboard and trigger email when mail is configured.
- Labeled posts with readable text enter Alibaba Cloud AIGC detection. Results are displayed separately from author labels.
Confidence reflects the detector's suspicion of AI generation. It is not the percentage written by AI.
