Nathan (@nschneid) and I have been working on an extension to AMR for tense and aspect information. I am putting the basic guidelines here in the text, as well as attaching the slides we created as a PDF.
In addition to general feedback, our main questions/issues for discussion are the following:
How accessible are the annotations to potential annotators? (Especially aspect)
Do others agree with the intuitions behind the aspect annotations?
Since we distinguish between :temporary (for states) and :continuing (for events), should we add the basic distinction of states and events to the annotation? Or should we collapse the distinction into one notion of ongoingness? (This gets to a broader question of how much do annotators need to infer about the lexical information in the verb itself, and how it lends itself to different tense and aspect forms).
Thank you!

Past event:
grow-01 :time (b / before
:op1 (n / now))
“The fire grew.”
“The fire had grown.”
“The fire was growing.”
Present event
grow-01 :time (n / now)
“The fire is growing.” / "The fire grows." (?)
Future event
grow-01 :time (a / after
:op1 (n / now))
“The fire will grow.”
“The fire will have grown.”
For relations between two times:Simultaneous Relation:
evacuate-01 :time (a / arrive-01)
“The evacuation will happen while the firefighters arrive.”
Begin-on Relation:
evacuate-01 :time (s / since
:op1 (a / arrive-01))
evacuate-01 :time (s / since
:op1 (d / date-entity :time
"17:00"))
“The evacuation will happen when/as soon as the firefighters arrive.”
“The evacuation will be/start at 5:00.”
End-on Relation:
evacuate-01 :time (u / until :op1 (s / safe-01))
“They are evacuating until everyone is safe”
Subsequence Relation:
evacuate-01 :time (a / after :op1 (a2 / arrive-01))
“The evacuation will happen when/after the firefighters arrive.”
Precedence Relation:
evacuate-01 :time (b / before :op1 (a / arrive-01))
“The evacuation will have happened when the firefighters arrive.”
Contained Relation:
evacuate-01
:supertime (e2 / evening)
“They evacuated in the evening.”
Containing Relation:
evacuate-01 :subtime (d / date-entity :time "17:00")
“The evacuation was underway at 5:00.”
ASPECT
Generic / generalizing
(habitual over events / general over kinds; states excluded)
:general +
E.g.
Present generic / generalizing (events, kinds):
“I eat apples.” = “I am eating apples these days.”
(e / eat-01 :general +)
“Fires are devastating.” = “Fires devastate.”
(d / devastate-01 :general +)
Past imperfect (events, kinds):
“It used to rain a lot.”
(r / rain-01 :general + :time before-now)
“I used to live here.” = “I lived here.”
(l / live-01 :time (before-now))
E.g. :temporary +
“I live here.”
(l / live-01 :time (n / now))
“I am living here.”
(l / live-01 :time (n / now) :temporary +)
E.g. :continuing +
“The fire was grwing.”
(g / grow-01 :time (before-now) :continuing +)
“The citizens are evacuating.”
(e / evacuate-01 :time (n/now) :continuing +)
E.g.
“The fire had grown.” = “The fire grew”
(g / grow-01 :time (before-now))
“The fire has grown.”
(g / grow-01 :statustime (n / now) :continuing ?)
Past event in past (with progress?):
“As of 5:00, the fire had grown.”
(g / grow-01 :statustime (b / before-now :time (d / date-entity 5:00) :continuing ?))
