“…This problem happens because ontologies use the Description Logics (DL) [1] as their formal basis, which is a decidable fragment of the first-order logic that only uses unary (concepts) and binary (roles) predicates. Therefore, ontologies do not naturally support representations for inputs such as "I slept well from 23:00 to J o u r n a l P r e -p r o o f Journal Pre-proof 04:00", "I had a posttraumatic stress disorder after my car accident", and "I had a heart attack in 1999"; while the current temporal extensions that are still compatible with the current ontology resources (e.g., reasoners and DL formalism) are limited in aspects related to uncertain time, the evolution of events, and relations between time concepts [2]. This lack of expressive and standards-compatible temporal representations restricts the range of reasoning processes because several time aspects, which are usually embedded in knowledge domains (e.g., health and education) [3], cannot be employed.…”
