Polish Comma Placement Test A
Subtask 6: Polish Comma Placement
Introduction and motivation
Polish comma placement depends on syntactic structure, including clause boundaries, subordination, coordination and certain participial constructions. Deciding whether a comma is needed at a given boundary often requires understanding the relationship between the surrounding phrases, rather than only the adjacent words.
The task evaluates punctuation decisions at predefined insertion positions, separating comma placement from unrestricted text editing.
Subtask description
The input is a Polish sentence in the sentence_with_positions field. Numbered markers such as [1], [2] and [3] indicate possible positions for commas. The model must determine which marked boundaries require a comma under standard Polish punctuation rules in that context.
Return the marker indices, not comma characters or a rewritten sentence. A sentence may require commas at several marked positions or at none of them. Unmarked positions are outside the scope of the task. Each number identifies a position within that sentence.
Dataset
The test-A dataset consists of 1,759 sentences based on the Polish CDSCorpus. Each sentence has between six and ten numbered candidate boundaries and includes a range of syntactic constructions. Markers are numbered consecutively within each item, starting at 1.
Input format
Each record supplies an id and the sentence_with_positions string:
{
"id": "a89c964e-6112-4979-8279-75250db45426",
"sentence_with_positions": "Bańki [1] mydlane [2] są puszczane przez [3] dziewczynkę w sukience [4] na trawie [5] a [6] za [7] nią stoi druga dziewczynka."
}
Model answer
The response is a JSON object with two fields:
commas: an array of integer indices marking required commas;optional: an array of integer indices identifying positions where a comma is permissible but not required.
For the example above:
{
"commas": [5],
"optional": []
}
List the indices in ascending order without duplicates. Use empty arrays where appropriate. Do not insert punctuation into the sentence or report character offsets.
Evaluation
The main metric is Exact Set Accuracy for required comma positions. The commas field is correct only when its indices exactly match the reference set. Missing a required position or adding an incorrect required position makes the item incorrect. Evaluation uses the marker numbers, not offsets in the sentence.
The optional field records permissible but non-obligatory comma positions separately from required positions.
Submission format
Submit one JSON object per line, holding id (the input item's id) followed by the answer fields: commas and optional. For the input example above, the line is:
{"id": "a89c964e-6112-4979-8279-75250db45426", "commas": [5], "optional": []}
The schema of these lines is output_schema.json, which is published beside inputs.jsonl. On the endpoint route the platform builds these lines from the model's answers, adding the id. A participant uploading a file must produce the same lines.
An example item
{
"id": "039275e7-33f4-421b-918d-25438ffe0a41",
"sentence_with_positions": "Aparat [1] fotograficzny [2] jest trzymany [3] w [4] rękach przez mężczyznę z [5] tatuażem [6] na prawej [7] ręce."
}
Prompt template
Each item's fields fill the placeholders, and the result is sent as the only user message: there is no system message.
Jesteś ekspertem od interpunkcji języka polskiego.
W zdaniu miejsca, w których może stać przecinek, są oznaczone numerami: [1], [2], [3], …
Twoim zadaniem jest wskazać wszystkie oznaczone miejsca, w których zgodnie z zasadami interpunkcji polskiej powinien stać przecinek.
Zasady:
1. W "commas" podaj numery wszystkich miejsc, w których przecinek jest wymagany, w kolejności rosnącej.
2. W "optional" podaj numery miejsc, w których przecinek jest dopuszczalny, ale nie wymagany, w kolejności rosnącej.
3. Jeżeli w żadnym oznaczonym miejscu przecinek nie jest wymagany, zwróć pustą listę w "commas".
4. Zwróć wyłącznie obiekt JSON w postaci: {"commas": [...], "optional": [...]}
5. Nie dodawaj wyjaśnień, komentarzy ani całego zdania.
Zdanie: {{ sentence_with_positions }}
