Critical Label and Three-Hour Badge

It is the high importance mark given to disasters, wars, or very vital policy changes that could deeply affect society.

The critical label prevents the most vital news in the feed from getting lost. These items go above the standard 99 ceiling and directly receive 100 points. A news item with a critical label is displayed in your app with a protected badge for 3 hours. A critical item starts at the very top but decays at the same speed; its privilege is its starting point, not durability.

Example: A major earthquake news item being published with a red critical label and carrying a badge for three hours.

The probability of encountering critical news in the real feed is only around 4-5%. To be able to detect this rare situation, a balanced weight system was applied during model training by increasing the weight of the rare class by approximately 10 times. The critical badge disappears at the end of 3 hours. The score, however, does not freeze at any point: it decays at the same speed as other items from the first moment and drops to around 97 in 40 minutes. Still, since it starts from 100, it stays above an ordinary item of the same age; the temporary noise during the day does not bury a vital development.
