PosterSentry Training Data

Human-validated training dataset for PosterSentry, the multimodal scientific poster classifier used in the posters.science quality control pipeline.

Developed by the FAIR Data Innovations Hub at the California Medical Innovations Institute (CalMI²).

Version

Version	Date	Notes
1.0.0	2026-08-18	Human-validated labels: every document was independently rated by three reviewers (Krippendorff's alpha 0.79) and the 430 contested documents were settled in a blinded adjudication review. Rows now carry document identifiers, DOIs, and label provenance. This is the corpus the published PosterSentry model is trained on.

The earlier unversioned release (April 2026) used heuristic repository labels and is superseded.

Dataset Description

Text extracted from real scientific documents, zero synthetic data. Every sample comes from an actual PDF downloaded from Zenodo or Figshare as part of the posters.science corpus, and every label was validated by people.

The corpus holds 3,298 documents: 1,651 posters and 1,647 non-posters (near-balanced by construction of the candidate pools, not by resampling).

Labeling

1. Survey: Three reviewers independently classified 3,486 candidate documents (poster, non-poster, or unsure) at survey.posters.science, casting 10,458 votes with an inter-rater Krippendorff's alpha of 0.79.
2. Adjudication: The 430 documents without a unanimous panel (369 decided two to one, 61 exact ties) were adjudicated in a blinded review: each document image was re-examined in randomized order without access to the panel votes or any model output.
3. Deduplication: 181 near-duplicate documents (matching normalized 300-character text prefixes) and 7 documents with unavailable PDFs were removed, leaving the 3,298 documents published here.

Non-posters include multi-page papers, conference proceedings, abstract books, newsletters, flyers, slide decks, and other documents mislabeled as "posters" in repository metadata.

Files

File	Description	Rows
poster_sentry_train.ndjson	Human-validated training corpus (text, labels, identifiers)	3,298

Format

NDJSON (newline-delimited JSON), one document per row:

{"id": "fxd4ylwf0byrtj307b5k3kpm", "doi": "10.5281/zenodo.1234567", "source": "zenodo", "text": "TITLE: Effects of Temperature on Enzyme Kinetics ...", "label": "poster", "label_source": "unanimous_panel"}

Field	Description
id	Survey document identifier (matches the paper's supplementary files)
doi	DOI of the source repository record (Zenodo or Figshare)
source	zenodo or figshare
text	First-page text extracted with PyMuPDF, whitespace-normalized, truncated to 4,000 characters
label	poster or non_poster (human-validated)
label_source	unanimous_panel (all non-unsure votes identical) or adjudicated (settled in the blinded review)

Label Distribution

Label	Count
poster	1,651
non_poster	1,647

By provenance: 2,875 documents carry a unanimous panel label and 423 an adjudicated label. Every row carries a DOI.

Usage

Load directly with HuggingFace datasets

from datasets import load_dataset

ds = load_dataset("fairdataihub/poster-sentry-training-data")
print(ds["train"][0])
# {"id": "...", "doi": "...", "source": "zenodo", "text": "TITLE: ...", "label": "poster", "label_source": "unanimous_panel"}

Use for PubGuard doc_type training

The poster texts in this dataset are also used by PubGuard to train its poster document-type classification head.
