Principles for Annotation
Prefer Core Roles over Non-core Roles
Thus:
Dependency graph for sentence: Kim bought a house. Token bought is labeled POSSESSION-INIT and has an edge labeled possessor to token Kim and an edge labeled possessum to token house.
Dependency graph for sentence: Kim wants to swim. Token wants is labeled META-NORM and has an edge labeled participant to token Kim and an edge labeled scene to token swim.
Rather than:
Dependency graph for sentence: Kim bought a house. Token bought is labeled POSSESSION-INIT and has an edge labeled CAUSER to token Kim and an edge labeled possessum to token house.
Dependency graph for sentence: Kim wants to swim. Token wants is labeled META-NORM and has an edge labeled EXPERIENCER to token Kim and an edge labeled scene to token swim.
Try Adding Arguments
When not sure how to frame a predicate, it can help to think of additional
arguments that the predicate could have and that are just not realized in this
instance. For example, what is the role of It in It is not important? If we
add an argument, we might get It is not important for the process, where
INFLUENCE seems to fit with It as influence and the
process as influenced. Thus:
Dependency graph for sentence: It is not important. Token not is labeled NEG and has an edge labeled negated to token important. Token important is labeled INFLUENCE and has an edge labeled influence to token It and an edge labeled SCENE to token not.
Prefer to Avoid Stacking
If something could be framed with either a single frame or two stacked frames, prefer using a single frame.
Thus:
Dependency graph for sentence: Kim seems happy. Token seems is labeled MESSAGE and has an edge labeled topic to token Kim and an edge labeled message to token happy.
Rather than:
Dependency graph for sentence: Kim seems happy. Token seems is labeled META-REALITY and has an edge labeled participant to token Kim and an edge labeled scene to token happy.
Prefer More Specific Frames
If not sure which of two frames to use, tend to prefer the more specific one.
For example, if TIME and CONDITION would both fit and you feel that
CONDITION is more specific, prefer CONDITION:
Dependency graph for sentence: Then I would never talk to them about boa constrictors. Token Then is labeled CONDITION and has an edge labeled has-condition to token constrictors.
Similarly, if an argument can be seen as assigning a role to another argument,
it is better to use META than, e.g., SITUATION:
Dependency graph for sentence: He buried himself in the contemplation of his treasure. Token buried is labeled META-INIT and has an edge labeled participant to token himself and an edge labeled scene to token contemplation. Token contemplation is labeled MESSAGE-INIT and has an edge labeled EXPERIENCER to token himself and an edge labeled topic to token treasure.
Use Comments if Not Sure
You are encouraged to use comments to note down any doubts and thoughts.
Comments can be added to the end of any line using the # symbol:
[TIME] generally (19) # ?
[has-time] fair (20)
[has-time] to - middling (24)
Obliqueness
Some annotation rules make reference to obliqueness, a concept used to rank
dependents by the syntactic “coreness” of their role. For our purposes, nsubj
dependents are least oblique, followed by obj, followed by iobj, followed
by obl.
Terminology
This is a list of terms and how they are used in this manual (not necessarily in linguistics in general, though I try to be compatible with widespread usage).
| Term | Explanation |
|---|---|
| adjunct | D is an adjunct of H if D is a dependent of H and not an argument, thus is assigned a role not by H but only by the adjunct construction – this means it must have a non-core role |
| argument | D is an argument of H if D is a dependent of H and is assigned a role by it – this can be a core role or a non-core role |
| dependent | if D, H are predicates, D is said to be a dependent of H if there is an edge from D to H in the annotation (either syntactic or non-syntactic) |
| event | a synonym for eventuality; sometimes also used as a synonym for process; I try to avoid the term due to its ambiguity |
| eventuality | a state or process |
| head | H is a head of D iff D is a dependent of H |
| predicate | a content word (noun, verb, adjective, or adverb) that evokes a frame |
| process | a dynamic eventuality, i.e., a transition over time through two or more states |
| scene | a synonym for eventuality |
| situation | a synonym for eventuality |
| state | a static eventuality, thus a state of affairs that does not include change over time |
