summarization_gl

Dataset Summary

summarization_gl is a Galician summarization dataset built from news articles and automatically extracted summaries from three Galician news sources:

Nós Diario
Que Pasa na Costa
Praza Pública

The dataset contains 80,829 instances in total. Each instance includes a news text and its associated summary.

Dataset Description

summarization_gl consists of pairs of:

summary: an automatically extracted summary
text: the corresponding full news article

The dataset includes materials from different news outlets with varying summary quality.

Dataset Structure

The dataset is distributed in JSONL format and is split into:

train: 56,600 instances
validation: 8,080 instances
test: 16,200 instances

The data in each split has been shuffled.

Each instance contains the following fields:

id: identifier of the summary-text pair; it typically indicates the news source and an internal numeric ID
summary: summary of the news article
text: full news article

Example

{
  "id": "NOS_58435",
  "summary": "O artista coruñés Pepe Galán leva desde os anos 70 vinculado o mundo da arte galega. Recoñecido popularmente polas súas esculturas e intervencións, cando se lle pregunta, prefire ser considerado como un \"artista multidisciplinar\" máis que cinguirse a unha única etiqueta como a de \"pintor\" ou \"escultor\".",
  "text": "Indo polas rúas da casa ao taller e do taller á casa, desprázome co ritmo de liturxia aprendida sobre o empedrado e o formigón... onde case sempre atopo algún dato, algunha novidade... Chega a ser unha relación familiar coa veciñanza e a cidade. Pola mañá gozo da paisaxe urbana mais non podo evitar ser crítico co deseño do espazo común..."
}

Intended Uses

This dataset can be used for:

fine-tuning summarization models for Galician
instruction tuning for summarization tasks
evaluation of summarization systems in Galician
research on low-resource summarization
experiments on summary quality, faithfulness, and domain adaptation in journalistic text

Limitations

The summaries were extracted automatically and are not uniformly high-quality.
Summary quality varies substantially depending on the source.
Many examples from Nós Diario are closer to article introductions or interview leads than to full summaries.
Many examples from Que Pasa na Costa are very short and may overemphasize the most click-attractive part of the article rather than the overall content.
The Praza Pública subset is of better quality, but the dataset as a whole is heterogeneous.
Because of this variability, the dataset may be more suitable for controlled experiments, filtering, or source-aware training than for direct use as a uniformly curated gold-standard summarization benchmark.

Data Format

The dataset is provided in JSONL format, with one JSON object per line.

Main fields:

summary (str): automatically extracted summary
text (str): corresponding news article
id (str, when available): identifier of the example
