LACRIMALit Ontology of Crisis

An event-centric model of crisis in Greek and Roman antiquity, built as a CIDOC-CRM extension.

Overview

LACRIMALit models crisis as an event rather than as a subject heading. An event is an action carried out by one or more agents that changes the state of a cultural, social or physical system; it has a location, a beginning and an end, causes, consequences, predecessors, successors and sub-events. The ontology is built as a domain extension of CIDOC-CRM's E7_Activity, with cause and consequence properties added, since CIDOC does not supply them.

Crises are typed into six spheres: environmental, financial, migrant, military, political and public health — each with its own subtypes, so that a Naval_Battle is a Battle with exactly one sea location.

It comes from the LACRIMALit project (2022–2025, funded by HFRI, PI Melina Tamiolaki, hosted at IMS-FORTH), and it is published as a journal article.

Example queries

What are the political crisis types?

PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX lac:  <http://ontologia.fr/OTB/lac#>

SELECT DISTINCT ?crisisName
WHERE {
  ?crisis rdfs:subClassOf* lac:Political_Crisis .
  ?crisis rdfs:label ?crisisName .
  FILTER (lang(?crisisName) = 'en')
}
ORDER BY ?crisisName

This is the first of six competency questions the ontology was built to answer. It returns the political crisis types: civil war, conspiracy, coup d'état, defection, exile, murder, ostracism, revolt, sedition and others.
