Time is a semantic category that indicates when a given event occurs. It may be expressed by attributes or by relations.
Time attributes
The values for the attribute time are the following:
- The UNL representation indicates the time rather than the grammatical tense of a form.
- There is no simple one-to-one relationship between tense forms and time. In English, for instance, the present (grammatical tense) may be used to represent the future (time)
- Iām going home tomorrow = go.@future.@recent (and not go.@present)
- @present is used to indicate an action at the present, and not habits, routines and statements
- I'm in Frankfurt. = @present
- I always come to school by cycle. = no time information
- The sun sets in the Occident. = no time information
- Time values may be combined.
- I'm going home tomorrow = go.@future.@recent
- I had been there = @past.@anterior
Time relations
Time may be expressed by the following relations:
Examples
- do now = tim(do,now)
- do since yesterday = tmf(do, yesterday)
- do until tomorrow = tmt(do, tomorrow)
- from yesterday to tomorrow = fmt(yesterday, tomorrow)
- do while walk = dur(do, walk)
