Search matches, labeled occurrences, and events

State what you count. The same paragraph can contain several string matches and several descriptions of one event.

One line counted in four units

…一生懸命にのぼAった甲斐があって…それからあのぼ×んやり光っている…この分でのぼCって行けば…自分ののぼAった後をつけて…よじのぼBって来る…ここへまでのぼAって来た…せっせとのぼBって参ります…

A: Kandata’s climb · B: the sinners’ climb · C: conditional · ×: not movement

grep -cF ‘のぼ’: lines
1 line (5 in the whole file)
grep -oF ‘のぼ’: search matches
7 matches (12 in the whole file)
Annotation: movement expressions
6, excluding あのぼんやり (×)
Events
A judgment: Kandata’s climb (A, described three times) and the sinners’ climb (B, described twice). のぼって行けば (C) is a condition, not a climb that happened

Text: an excerpt from line 11 of story.txt (one paragraph of part 二), the Soranoha plaintext of 「蜘蛛の糸」.

Before reporting a number, state the unit, included rows or passages, and source version.

How do individual passages change the count?
Passage Search match Labeled occurrence Event
あのぼんやり光っている (part 二) Yes: のぼ is part of あのぼんやり Not a movement expression None
この分でのぼって行けば (part 二) Yes Up; “Not stated whether it happens” (Uu); evidence: conditional ば None: Kandata predicts climbing out
のぼれなくなってしまいました (part 二) Yes Up; “Does not happen / did not happen” (CT-); evidence: のぼれなく None: he cannot climb further
ややしばらくのぼる中に and 一生懸命にのぼった甲斐があって (part 二) Yes: each contains のぼ Two rows: up, “Happens / happened” (CT+) One climb, described twice

A token is a unit produced by a text analyzer; its boundaries depend on the analyzer and dictionary. Our movement expressions may span several tokens.

When you cannot choose a label

“Not stated whether it happens” (Uu) means the narrator does not state whether the movement happens. Use “Defer judgment” when you cannot choose a label.

Keep the row for that passage. If you cannot choose a label for Direction or “Does the movement happen?”, enter “Defer judgment” in that field and write your reason in Evidence.

Problem What to do
Not enough context Read the full paragraph
The text does not state who moves Leave Actor blank; write the wording you checked in Evidence
You cannot choose a label using the criteria Enter “Defer judgment”; write what needs clarification in the criteria
You and another reader disagree Check the evidence for each judgment in the text

If you exclude rows with deferred judgments from a count, also report how many rows you excluded. If different possible labels change the result, give the count for each case.

Compare independent labels

Compare labels recorded before discussion; keep later revisions separately.

How is inter-annotator agreement measured?

Inter-annotator agreement (IAA) quantifies how consistently annotators apply the same criteria. Raw agreement is matching labels divided by occurrences compared, calculated separately for each field:

Field Example
Direction 5 matching labels out of 5: 100%
Movement judgment 3 matching labels out of 5: 60%

For each field, compare only rows where both readers supplied a label. Report deferrals and unfinished rows separately; two deferrals do not count as matching judgments. Uu is a completed judgment.

Agreement quantifies consistency, not correctness. Five selected examples cannot establish reliability. For larger samples, chance-corrected measures such as Cohen’s κ account for agreement expected from label frequencies; choose a measure suited to the task and annotator count.
