Timeliness Judgment (时效性判断)
Before including news, verify timeliness:
| Indicator |
Fresh |
Stale |
| Publish date |
Within 2 days |
Older than 7 days |
| Date string in URL |
Contains current date (2026-02-*) |
No date or old date |
| Source freshness |
News sites, blogs |
Static docs |
| Content keywords |
"今日", "最新", "just announced" |
"历史", "回顾", "总览" |
Priority: Prefer news with publish dates within 2 days. Stale news (>7 days) should be excluded.
Source attribution: Always include clickable source links.
Usage Guidelines
DO
