=== Temporal reasoning ===
{{further|Spatial–temporal reasoning}}
Temporal reasoning is the ability to make presumptions about humans' knowledge of times, durations and time intervals. For example, if an individual knows that Mozart was born after Haydn and died earlier than him, they can use their temporal reasoning knowledge to deduce that Mozart had died younger than Haydn. The inferences involved reduce themselves to solving systems of linear inequalities.<ref>{{Cite web|url = http://www-formal.stanford.edu/leora/commonsense/|title = Temporal reasoning}}</ref>

To integrate that kind of reasoning with concrete purposes, such as [[natural-language understanding|natural language interpretation]], is more challenging, because natural language expressions have context dependent interpretation.<ref>Liu, Hugo, and Push Singh.
