Taxonomy

Event categories & story themes — at a glance

Every Event in GDELT Cloud carries a structured classification so you can filter, route, and reason over global news the same way an analyst does. Three lenses sit on top of the article stream: Conflict events (ACLED-style), CAMEO+ events across ten structural domains, and Stories — daily clusters with scope and theme tags.

Conflict · ACLED-style

Political violence, demonstrations & strategic developments

Each conflict event is coded with a 3-level hierarchy — disorder type → event type → sub-event type — plus actor pair, geography, fatalities, and a Goldstein-style cooperation/conflict reading. We follow the ACLED codebook independently; we don't license or redistribute ACLED data.

Disorder

Political violence

Armed conflict, attacks, explosions, and targeted violence by armed actors.

Battles

Armed combat between organized groups.

Armed clashGovernment regains territoryNon-state actor overtakes territory
Explosions / Remote violence

Attacks using weapons that allow distance between attacker and target.

Air/drone strikeShelling/artillery/missile attackRemote explosive/landmine/IEDSuicide bombGrenadeChemical weapon
Violence against civilians

Deliberate violence by armed actors targeting unarmed non-combatants.

AttackAbduction/forced disappearanceSexual violence
Disorder

Demonstrations

Organized protests, riots, and crowd-driven violence.

Protests

Organized demonstrations.

Peaceful protestProtest with interventionExcessive force against protesters
Riots

Collective violence, often spontaneous.

Violent demonstrationMob violence
Disorder

Strategic developments

Concrete actions that change the conflict landscape without a battle.

Strategic developments

Confirmed structural changes — agreements, arrests, base establishment, territorial handovers.

AgreementArrestsHeadquarters or base establishedLooting/property destructionNon-violent transfer of territoryChange to group/activityDisrupted weapons useOther
Actor types

Each event records up to two actors with normalized type codes 1–8: state forces, rebel groups, political militias, identity militias, rioters, protesters, civilians, and external/other forces. The interaction field encodes the pair as a normalized label like State forces–Rebel groups or Protesters only.

Geography & precision

Country (ISO-3) is always present. Region, admin1, admin2, named place, and decimal lat/lng narrow further when the source supports it. A geo_precision code (1–3) tells you whether the location is exact, approximate, or only known at the province level.

CAMEO+ · 10 structural domains

Beyond conflict — the structural signals that move geopolitics & markets

CAMEO+ extends the classic CAMEO political-event taxonomy and ACLED conflict layer into the structural domains that shape geopolitics, markets, and instability — economic shocks, corporate moves, technology jumps, infrastructure events, climate hazards, public health, demographic flows, and the information space.

Metrics

Numbers that turn events into signals

Beyond the categorical taxonomy, every event carries domain-aware numeric metrics. Together they let you score, rank, and route events into agentic workflows — from market-impact alerts to humanitarian briefings.

Goldstein scale
−10 to +10

Cooperation-to-conflict spectrum for political and conflict events. Negative is conflictual, positive is cooperative.

Magnitude
0 to 10

Domain-specific severity. For economic events, 10 is a sovereign default; for environment, a major catastrophe; for technology, a frontier capability jump.

Systemic importance
0 to 10

How many states, populations, or sectors the event materially affects. Cross-border crises rate higher.

Propagation potential
0 to 10

Speed and likelihood of cascading effects — viral disinformation, cyber events, and supply-chain shocks rate highest.

Market sensitivity
0 to 10

How much the event tends to move financial markets. Macro and policy actions dominate; cultural events rate low.

Stories

Daily article clusters with scope & theme

A Story is a daily cluster of articles that converge on a single narrative. Stories carry a free-text label, a scope band (how widely the narrative is being covered), and a thematic category drawn from the same structural domains as Events. Story categories are emitted by the clustering layer — they're not a fixed enum, but cluster around recurring buckets.

Scope levels

Each Story is tagged with one of four geographic scope bands. Use scope to filter for breaking-local versus internationally-covered narratives.

Local

A single city or sub-national area, with sources rooted to that place.

National

Coverage spans a single country and its national press.

Regional

A multi-country region — e.g. the Sahel, the Levant, Southeast Asia.

International

Major outlets across multiple regions are converging on the story.

Theme buckets we surface

Categories are not a closed list — the clustering layer can emit fresh labels for novel narratives — but most stories land in one of these recurring buckets.

Conflict & SecurityDiplomacy & PoliticsEconomy & MarketsEnergy & InfrastructureClimate & EnvironmentHealth & DiseaseMigration & DemographicsTechnology & AIInformation & MediaCrime & Justice

Stories link back to the Events generated from their cluster — so you can pivot from a structured Conflict or CAMEO+ event into the article-level evidence that produced it, and out again into the cluster of related stories that touched on the same narrative.
