# PaperLens-Vision

Vision version of the **OpenReview-ICLR** and **arXiv** PaperLens datasets.

Each row is one unique paper. We release **all** extracted papers — not every paper here is used in our downstream training/eval sets. The papers that *are* used are denoted by the `references` field, which lists every internal `(release_name, release_split)` pair the paper belongs to (a single paper can belong to multiple). [`reconstruction.py`](https://github.com/zlab-princeton/PaperLens/blob/main/paperlens-training-and-inference/scripts/reconstruction.py) reads this field to materialize the original sharegpt `data.json` for any of the ~20 publishable vision keys.

## Configs (subsets)

- `arxiv` — papers from arxiv (per_venue + 21k families + residual + the arxiv side of combined).
- `openreview-iclr` — papers from ICLR via OpenReview (balanced_original + max_rejects + train_50pct/75pct + the iclr side of combined).

```python
from datasets import load_dataset
ds_arxiv = load_dataset("skonan/PaperLens-Vision", "arxiv",           split="papers")
ds_iclr  = load_dataset("skonan/PaperLens-Vision", "openreview-iclr", split="papers")
```

## Schema

| field | type | description |
|---|---|---|
| `paper_id` | `string` | arXiv id or OpenReview submission id |
| `title` | `string` | paper title |
| `content` | `string` | prompt-stripped body (title + abstract + `<image>` placeholders (one per page)) |
| `metadata` | `string` | JSON blob — venue, year, authors, ratings, decision, … |
| `label` | `string` | `"Accept"` or `"Reject"` |
| `references` | `list<list<string>>` | each entry is `[release_name, release_split]` — the internal splits this paper belongs to |
| `images` | `list<struct<bytes,path>>` | one PNG per page, bytes inline |

## Reconstructing the sharegpt `data.json` files

[`reconstruction.py`](https://github.com/zlab-princeton/PaperLens/blob/main/paperlens-training-and-inference/scripts/reconstruction.py) rebuilds any of the publishable internal keys (e.g. `arxiv_50_50_21k_vision_..._y24up_test`) byte-identically from this dataset. Setup + run:

```bash
git clone https://github.com/zlab-princeton/PaperLens.git
cd PaperLens/paperlens-training-and-inference
uv sync

# arxiv training set
uv run python scripts/reconstruction.py \
    --hf_vision_repo skonan/PaperLens-Vision \
    --dataset_keys arxiv_50_50_balanced_per_venue_vision_wmetadata_filtered24480_train

# openreview-iclr training set
uv run python scripts/reconstruction.py \
    --hf_vision_repo skonan/PaperLens-Vision \
    --dataset_keys iclr_2020_2023_2025_2026_85_5_10_balanced_original_vision_labelfix_v7_filtered_filtered24480_train
```

Reconstructed files land in `./data/` by default (override with `--data_root <path>`): `data/<dataset_key>/data.json` (sharegpt rows) and `data/dataset_info.json` (LlamaFactory entry), and `data/images_{arxiv,iclr}/<paper_id>/page_*.png` for the per-page PNGs.

The release ships a `manifest.json` sidecar mapping each internal `dataset_info.json` key → `(release_name, release_split, columns, file_name)`, so reconstruction reproduces conversations, `_metadata`, `accept_reject_label` (where applicable), and image bytes exactly.

> ⚠️ Reconstructing the full vision tree produces one PNG per page, creating over 1M files for the whole release — run on a fileset with inode headroom.
