## Dataset Description

- **Paper:** [DACSA: A large-scale Dataset for Automatic summarization of Catalan and Spanish newspaper Articles](https://aclanthology.org/2022.naacl-main.434/)
- **Point of Contact:** [Vicent Ahuir](mailto:viahes@dsic.upv.es)

### Dataset Summary

The Dataset for Automatic summarization of Catalan and Spanish newspaper
Articles (DACSA) corpus. It is a high-quality large-scale corpus that can be
used to train summarization models for Catalan and Spanish. The data provides
pairs of news article and its summary from different newspapers for both, the
Catalan and the Spanish languages. Regarding the Catalan set, there are 725,184
sample pairs from 9 newspapers, regarding the Spanish set, the corpus provides
2,120,649 sample pairs from 21 newspapers.

### Languages

-  `catalan`
-  `spanish`

### Download

```python

import datasets

ACCESS_TOKEN = "hf_read_access_token"

ds_es = datasets.load_dataset("ELiRF/dacsa", "spanish", token=ACCESS_TOKEN)
ds_ca = datasets.load_dataset("ELiRF/dacsa", "catalan", token=ACCESS_TOKEN)
```

## Dataset Structure

### Data Fields
-  'id': A string representing the article ID.
-  'summary': A string containing the article summary.
-  'article' : A string containing the article text. 


### Data Splits

Four splits are provided for each language set
- **train**: samples for training models
- **validation**: samples for adjusting and validating models
- **test.i**: test samples from newspapers present in _train_ and _validation_ splits
- **test.ni**: test samples from newspapers not present in training and validation splits

The _validation_ and _test-i_ splits contain a uniform distribution of samples
from each newspaper source.

Languages     | ISO 639-1 Code | Train   | Val   | Test.i | Test.ni | Total   |
--------------|----------------|---------|-------|--------|---------|---------|
Catalan       | ca             | 636596  | 35376 | 35376  | 17836   | 725184  |
Spanish       | es             | 1802919 | 104052 | 104052 | 109626 | 2120649 |

    abstract = "The application of supervised methods to automatic summarization requires the availability of adequate corpora consisting of a set of document-summary pairs. As in most Natural Language Processing tasks, the great majority of available datasets for summarization are in English, making it difficult to develop automatic summarization models for other languages. Although Spanish is gradually forming part of some recent summarization corpora, it is not the same for minority languages such as Catalan.In this work, we describe the construction of a corpus of Catalan and Spanish newspapers, the Dataset for Automatic summarization of Catalan and Spanish newspaper Articles (DACSA) corpus. It is a high-quality large-scale corpus that can be used to train summarization models for Catalan and Spanish.We have carried out an analysis of the corpus, both in terms of the style of the summaries and the difficulty of the summarization task. In particular, we have used a set of well-known metrics in the summarization field in order to characterize the corpus. Additionally, for benchmarking purposes, we have evaluated the performances of some extractive and abstractive summarization systems on the DACSA corpus.",
