Methodology

The 222 countries and territories covered are treated under identical rules: the same detection thresholds, the same topic families, the same barometers. No country is favoured in the ranking, and the Global Front Page deliberately caps each country's representation to avoid any centralisation.

Terra-Orb only reads public content: RSS/Atom feeds, sitemaps, public pages, public social media accounts, structured data. No paywall bypassing, no classified data, no closed databases. robots.txt directives are respected.

Every ranked article carries the reason for its score: freshness, pick-up by other media, source reliability, intensity, reach, and topic clarity. Every early signal shows its deviation from normal, its spread speed and its confidence level. Nothing is a black box.

Only publications from the last 24 hours are retained. Articles covering the same information are grouped into a single event: the wall displays the original and counts the pick-ups, without duplicating.

Ranking, dating, geography and signals rely on verifiable rules, not on a generative model. AI only steps in to translate headlines and write summaries based solely on aggregated figures — never to invent facts.

Projections at 6, 24 and 72 hours are statistical extrapolations with a confidence level attached, not predictions. Early signals are probabilistic: a signal may not be confirmed, and Terra-Orb then displays it as such.
