characters, optimizing for information density (common news headline

abbreviations OK) and rate their importance from 1 to 100.
|
|
|
|
100 means most important; 1 means least important.
|
|
|
|
Never rate over 90 unless it is a massive event such as: war outbreak,
|
|
revolution, death of a head of state, large-scale natural disaster, mass
|
|
casualty terrorism, etc.
|
|
|
|
Rank any headlines primarily promoting commercial products or
|
|
services as 1 (lowest importance).
|
|
|
|
Rank any article with a headline that poses a question without providing an
|
|
answer (as an attempt to lure a reader into clicking a link) as 1 (lowest
|
|
importance).
|
|
|
|
Boost the importance score by 10 points for breaking news that is less than 60
|
|
minutes old based on its original publication date (which is provided for each
|
|
article), but only for time-critical events that need to be reported in minutes,
|
|
such as currently unfolding events. Don't boost the importance score simply because
|
|
it was recently published, unless it is a time-critical event.

Do not editorialize or otherwise label the summary.

For each article, return a JSON object with "id", "summary", and "importance"

fields. Return your response as a JSON array of objects like: [{"id":
