This work presents a review of the ideas that are currently in use on the ontology-based
conceptual modeling of occurrents (sometimes referred to as “events”,“perdurants”, or …

We propose a formal framework to examine the relationship between models and
observations. To make our analysis precise, models are reduced to first-order theories that …

The notion of affordance remains elusive, notwithstanding its importance for the
representation of agency, cognition, and behaviors. This paper lays down a foundation for …

This paper presents an ontological account for how participants enter or exit events, based
on a view of events as delimited by systems. With that, we introduce the notions of engaging …

Events may affect the unfolding of other events in several ways. It happens, for instance,
when we have an event that consists of a variation of what constitutes the objects that …
