# Event ontology index

Sixteen ontologies turn event reporting into distinct, testable research variables.

Raw text does not tell a model whether an event is a threat, sanction, cyber technique, disaster, industry exposure or scheduled information release. These ontologies preserve those distinctions as stable categories that can be filtered, compared and tested through time. Each guide defines the classification boundary, exposes exact World V1.2 counts and uses three example usages to show what the ontology reveals. Start with the research question below, then inspect every category and download the underlying evidence.

[55 categories Flat 100.0% coverage IPTC News Genre Separate what happened from how the information was packaged before it enters an event study. See policy expectations resolve into results, obituaries isolate recycled history, and iPhone reporting move beyond previews. Explore ontology →](https://nosible.com/ontologies/iptc-genre)

See AI concentrate in fewer industries, chip shortages expose automakers, and property stress reach regional banks. Explore ontology →](https://nosible.com/ontologies/gics)

[300 categories 2 levels 7.8% coverage ICD-11 Chapters and Blocks Separate health reporting into clinically meaningful cohorts without relying on unstable disease-name keyword lists.
