# Dataset Card for CEIL
 
## Dataset Description

- **Website:** https://aina.bsc.es
- **Point of Contact:** [Carlos Rodríguez-Penagos](carlos.rodriguez1@bsc.es)

### 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](https://creativecommons.org/licenses/by/4.0/) licence. 

This dataset was developed by [BSC LangTech Unit](https://langtech.bsc.es/) as part of the [Projecte AINA](https://politiquesdigitals.gencat.cat/ca/economia/catalonia-ai/aina/), to enrich the [Catalan Language Understanding Benchmark (CLUB)](https://club.aina.bsc.es/).


### Supported Tasks and Leaderboards

Named Entities Recognition, Language Model

### Languages

The dataset is in Catalan (`ca-CA`).

## Dataset Structure

### Data Instances

Three two-column files, one for each split.

### 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

#### Who are the source language producers?

Annotation Subcontracted to M47Labs.

Guidelines available at Zenodo: XXXXXXXXX

### Annotations

#### Annotation process

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

#### Who are the annotators?

Original annotators from 

### 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.
