# QE4PE Pretask

The goal of the `pretask` is to familiarize translators with the GroTE interface, indentify potential issue and inform the modality assignment for the `main` task to ensure a uniform distribution of editing times across modalities. Refer to the [translators' guidelines](./pretask_eng-nld_guidelines.pdf) for additional details about the task.

## Inputs

The `pretask` uses six documents ranging 6-10 from the same `wmt23` collection of the `main` task that were matching all the `main` task requirements, but were not selected for the main collection.
We use the `supervised` highlights produced by XCOMET-XXL to familiarize translators with editing highlighted texts with highlights being assumed to be of a good but not "perfect" quality (as opposed to `oracle`). Word-level error spans are extended to match closest word boundaries whenever necessary.

## Main Task Assignments

From the `pretask` results, we create 3 groups per translation direction representing faster (1), average (2) and slower (3) translators by splitting the time-ranked list of translators in three blocks of equal size. In every block, we assign a modality to each translator randomly (random seed = 42). All gaps >5 minutes in the logs are omitted from the calculation to account for accidental AFK time during logging.

The final assignments (also in `main_task_assignments.json` for machine-readable format) are:
