Temporal relations refer to the relationship between events or actions that occur at different points in time. The constituents of temporal relations can be understood through three key elements:
Time intervals: These are the periods of time between two events or actions. They can be measured in units such as seconds, minutes, hours, days, weeks, months, or years.
Event sequences: These are the orderings of events or actions in time. For example, event A may occur before event B, or event C may occur simultaneously with event D.
Causality: This refers to the relationship between events or actions where one event or action causes another. For example, if event E causes event F, then F cannot occur before E.
Together, these three constituents of temporal relations help us understand the relationships between events or actions that occur at different points in time. By analyzing these relationships, we can better understand the causes and effects of different events, and how they relate to each other over time.
