PageGuide user study — results
One row per answered task from the PageGuide web study, on the task selection the analysis
dashboard uses by default. rows.csv is the row-level data; the two behavior_*.csv files are
the aggregates plotted in the behavioural figures (mean, sd, se and n per cell). outcomes.csv
carries accuracy, localization F1 and its two halves, and the timing stages — mean, sd, se,
median and quartiles per cell.

Conditions
Every participant sees both arms, interleaved task by task:
nongrounding— the agent reports an answer with no evidence attached.grounding— the same claims, with citations into the page and saved image crops.
Task selection
Some tasks are excluded from their card by default. The figures and these files use the same selection, so they agree with the dashboard:
| Facet | Left out | Why |
|---|---|---|
| Find × Text | MARS-v1 | a disputed answer key |
| Find × Visual | MUFC-V1, PEDANT-V1 | two runs whose grounded locate time is ~14× the others while accuracy and localization stay flat |
| Guide × Text | gv2-ed05a7b6-kk24zp, gv2-ms9iw0pq-5kj5zr, gv2-msf02a2n-88li4p, gv2-msf5mo9m-qm5brt | three duplicate re-recordings, plus both recordings of the New York goal |
| Guide × Visual | gv2-msf1pyqv-omt0hz | a run whose ground truth blames one step under two error types, so no participant can score it in full |
What is not here
Participants' free-text notes are omitted, and session ids are replaced with a per-export
participant integer. Both are deliberate: the notes are the only column that can carry
something about a person rather than about a task.
Scoring
Localization quality is F1. For Find it is over the passages picked; for Guide it is the mean of an F1 over the error types named and an F1 over the steps blamed, with a correct "no error" scoring in full on a run that contains none. A null precision means the participant predicted nothing, which is zero true positives, so its F1 is 0 rather than missing.
