Components:
Allen relationship [meets
1
], effective time period, episode, object,
representation.
temporal extent state transformation taxonomy, {
lengthen
}
Mechanics:
those temporal extent state transformations that increase the number
of clock ticks within the effective time period of an episode.
Semantics:
the temporal extent state transformation that enlarges the effective
time period of an episode.
Components:
clock tick, effective time period, episode, object.
temporal extent state transformation taxonomy, {merge}
Mechanics:
the temporal extent state transformation that adds the representation
of an object to an effective time period that [meets
1
] the effective time
period of an earlier episode of that object, and that also [meets] the effective
time period of a later episode of that object.
Semantics:
the temporal extent state transformation that transforms two adjacent
episodes of the same object into one episode.
Components:
effective time period, episode, Allen relationship [meets], Allen
relationship [meets
1
], object, representation, temporally adjacent.
temporal extent state transformation taxonomy, {
modify
}
Mechanics:
those temporal extent state transformations that increase or decrease
the number of clock ticks occupied by an object, but that neither increase nor
decrease the number of episodes that represent that object.
Semantics:
those temporal extent state transformations that add or remove clock
ticks from one or more episodes.
Components:
clock tick, episode, object, represent.
temporal extent state transformation taxonomy, {shorten backwards}
Mechanics:
the temporal extent state transformation that removes the
representation of an object from one or more contiguous clock ticks that
were the latest clock ticks of an episode of that object.
Semantics:
the temporal extent state transformation that removes the effective
time period of an episode from a later time period.
Components:
clock tick, contiguous, effective time, episode, object,
representation.
temporal extent state transformation taxonomy, {shorten forwards}
Mechanics:
the temporal extent state transformation that removes the
representation of an object from one or more contiguous clock ticks that
were the earliest clock ticks of an episode of that object.
Semantics:
the temporal extent state transformation that removes the effective
time period of an episode from an earlier time period.
Components:
clock tick, effective time, episode, object, representation.
temporal extent state transformation taxonomy, {
shorten
}
Mechanics:
those temporal extent state transformations that reduce the
number of clock ticks within the effective time period of an episode of that
object.
Semantics:
the temporal extent state transformation that reduces the effective
time period of an episode.
Components:
clock tick, effective time period, episode, object.
