Dataset Summary
This is a dataset for Named Entity Recognition (NER) in Catalan. It adapts AnCora corpus for Machine Learning and Language Model evaluation purposes.
AnCora corpus is used under CC-by licence.
This dataset was developed by BSC TeMU as part of the Projecte AINA, to enrich the Catalan Language Understanding Benchmark (CLUB).
Supported Tasks and Leaderboards
Named Entities Recognition, Language Model
Languages
The dataset is in Catalan (ca-CA).

Data Fields
Every file has two columns, with the word form or punctuation symbol in the first one and the corresponding IOB tag in the second one.
Data Splits
We took the original train, dev and test splits from the UD version of the corpus
- train: 10,630 examples
- validation: 1,429 examples
- test: 1,528 examples
Dataset Creation
Curation Rationale
We created this corpus to contribute to the development of language models in Catalan, a low-resource language.
Source Data
Initial Data Collection and Normalization
AnCora consists of a Catalan corpus (AnCora-CA) and a Spanish corpus (AnCora-ES), each of them of 500,000 tokens (some multi-word). The corpora are annotated for linguistic phenomena at different levels. AnCora corpus is mainly based on newswire texts. For more information, refer to Taulé, M., M.A. Martí, M. Recasens (2009): "AnCora: Multilevel Annotated Corpora for Catalan and Spanish”, Proceedings of 6th International Conference on language Resources and Evaluation.
Who are the source language producers?
Catalan AnCora corpus is compiled from articles from the following news outlets: EFE, ACN, El Periodico.
Annotations
Annotation process
We adapted the NER labels from AnCora corpus to a token-per-line, multi-column format.
Who are the annotators?
Original annotators from AnCora corpus.
Personal and Sensitive Information
No personal or sensitive information included.
Considerations for Using the Data
Social Impact of Dataset
We hope this corpus contributes to the development of language models in Catalan, a low-resource language.
