Dataset Description

Website: https://aina.bsc.es
Point of Contact: Carlos Rodríguez-Penagos

Dataset Summary

(Catalan Entity Identification and Linking).This is a dataset for complex Named Entity Recognition (NER) created by the AINA project in the BSC for Machine Learning and Language Model evaluation purposes in Catalan. It contains 9 main types and 52 subtypes on all kinds of short texts, with almost 59K documents.

[CEIL corpus] is used under CC-by licence.

This dataset was developed by BSC LangTech Unit 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

80/20 Train and development sets, balanced for all NERC tags. Test set incloudes documents that contain overall all the possible types in the corpus.

Dataset Creation

Curation Rationale

We created this corpus to contribute to the development of language models in Catalan.

Source Data

Documents were gathered from various online sources:

Tweets about different topics, such as catalan independence, coronavirus, benidormfest, vaccines, etc.
Newswire from nacio digital (Motor) Vilaweb (opinion pieces), Agencia Catalana de Noticies (Economy and Memoria Histórica)
Various threads from RacoCatalá forum
Viquipedia articles (woman bios, film synopses, etc.)
OTHER: Parliament proceedings, restaurant online reviews, etc.

Initial Data Collection and Normalization

The word tokenization used to convert offset annotations into CONLL files was done using spacy

Annotations

Annotation process

We adapted the NER labels from to a token-per-line, multi-column format.

Who are the annotators?

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.
