Ontology field guide
By NOSIBLE Research
World Geography
World Geography shows where an event occurs, allowing local shocks and cross-border propagation to be measured separately through time.
A source location is not an event location. A London publisher can report an attack in Yemen, a factory stoppage in Germany or a freight response in India. Collapsing those places into the publisher's country destroys the transmission path. World Geography assigns each event a continent, region and country using stable geographic labels. The resulting path follows the reported event itself through time.[1][2]
Researchers can use the hierarchy to construct local cohorts, measure geographic diffusion and join events to country, port, trade or asset exposures. The field does not identify publisher domicile, issuer revenue geography or causal spillovers. This guide provides the full structure, World base rates, a Red Sea shipping study and data for testing geographic event signals against independently defined exposures.

Foundations
World Geography classifies event locations without inferring source or issuer exposure
The ontology follows a three-level continent, region and country hierarchy grounded in ISO country codes and United Nations regional groupings. Stable country labels support joins across time, while the parent path allows aggregation when a country sample is too sparse. Repeated regional labels on different paths remain explicit in the explorer.[1][2]
World assigns the event location. It does not identify publisher location, exchange venue, company domicile or economic exposure. A factory event in Germany can affect suppliers and securities elsewhere. Join each event location to a separate, point-in-time exposure map before testing spillovers.
Categories
World Geography organises 231 categories into continents, regions and countries
The hierarchy contains six continent roots, regional groupings and 194 country leaves across three levels. Every World event receives one geographic path. The explorer exposes definitions, stable codes, full paths and World V1.2 counts. Search and bounded expansion keep the full geography accessible without separate country pages.[1][2]

Example Usage: Red Sea reporting expands from three regions to six as carriers reroute shipping
The cohort contains 1,766 English-language events that mention a Red Sea, Houthi, Bab el-Mandeb or Suez identifier and a maritime-shipping term. Outside-Middle-East event share rises from 27.9% during initial attacks to 46.7% during carrier rerouting. Effective regions rise from 2.95 to 5.56, revealing diffusion that global counts miss.[3]
Carrier rerouting provides the mechanism for geographic diffusion. Weekly changes in operational and ticker-linked financial coverage show a weak six-week relationship (r = 0.17), but the lag-adjusted test is not significant (p = 0.119). The evidence supports broader regional exposure, not a stable propagation delay, trade effect or price response.[4][5][6]
Monthly coverage divides the fixed Red Sea shipping cohort by all English World events. Regional measures use shares within that cohort. The lead test compares weekly changes in same-region normalized rates and corrects for selecting the strongest lag. The study establishes reporting diffusion, not trade, inflation, freight-rate or return effects. Those remain separate questions for external economic data and cannot be inferred from coverage alone.

Example Usage: March banking stress cuts North America’s share as Western Europe quadruples
March 2023 banking stress begins as a North American event and rapidly acquires a European dimension. Normalized coverage rises from 546 to 917 events per million after 13 March. North America falls from 79.7% to 47.1% of assigned geography, while Western Europe rises from 9.8% to 40.4%.[7]
The geographic mix distinguishes local failure from cross-border transmission. Silicon Valley Bank and Signature Bank drive the first phase; Credit Suisse dominates the next. Effective regional concentration rises from 1.54 to 2.58 regions. That change separates liquidity stress from a cross-border banking-risk regime before price, funding and policy tests.[8]
- Western Europe
- +30.6pp
- North America
- -32.6pp
- Effective regions
- +1.04
- Normalized coverage
- +371 per million
The fixed cohort explicitly names Silicon Valley Bank, Signature Bank, First Republic or Credit Suisse. It contains 123 assigned events before 13 March and 940 afterwards across the matched North American and European stress phases in March.

Example Usage: COVID-19 coverage moves from East Asia into North America and South Asia
COVID-19 reporting moves decisively out of East Asia as global transmission accelerates. East Asia falls from 40.9% to 3.7% of assigned geography after 20 February 2020. North America rises from 18.8% to 48.9%, South Asia reaches 18.8%, and normalized cohort coverage increases from 33,683 to 409,295 events per million.[9]
The result measures a shift in reporting geography, not wider regional diversity. Attention moves toward North America, South Asia and Western Europe as transmission accelerates. Geography labels expose that redistribution and create region-specific event clocks for testing travel restrictions, supply-chain disruption, policy responses and cross-market transmission around the pandemic declaration in early 2020.[10]
- East Asia
- -37.2pp
- North America
- +30.1pp
- South Asia
- +8.1pp
- Normalized coverage
- +375,612 per million
The fixed English cohort requires COVID, COVID-19, coronavirus or SARS-CoV-2. Weekly shares use Geography-assigned cohort events; normalized attention divides by all English World events. The pre-registered boundary is 20 February 2020.
