1. Something that happens : occurrence (Source: Merriam-Webster's Collegiate Dictionary. (
2. A happening or occurrence that does not persist in the relations of a thing, but occurs in a certain place during a particular interval of time. This is a widely used but very ambiguous conception. No agreement has been achieved with regard to its simple nature, its qualities, or its relations. Scholars are divided whether an event should be classified as an object, a fact, a state of affairs, or simply a change, whether it is universal or particular, and over the criteria to individuate events. (p.233 'event', The Blackwell Dictionary of Western Philosophy, 2004)
3. Generally regarded as either a change, usually of short duration, in the qualities or relations such as spatial relations of a thing, or as the possession of a property or relation by something at or for a time. Many of the problems about events concern how they are related to other things (p.129, The Routledge Dictionary of Philosophy, Fourth Edition)
4. From Wordnet (
  • Something that happens at a given place and time
  • A phenomenon located at a single point in space-time
  • A phenomenon that follows and is caused by some previous phenomenon
5. A wholeness type which has unity. It is not Open-ended in the sense that it has specified either starting or ending or middle(pass-by event) events. It can't change. It is state-less. It is not dissective. Every existence is an instance of an event. Any object cannot exist without participating in an event. For example, Mr. A, an instance of human cannot exist in the real world as it is alone, but must exist as a participant slot filler of an event/process instance with some action which he might be perfoming at all times. It is different from an instance of an action which is a process and is a part of an event instance. It is a bare event that exists independently of human recognition(before recognition). It follows B-series of time. (YAMATO,
6. A temporal slice of a processual (Wonderweb Deliverable 18, p.66.,
