Dataset Card for Hausa VOA NER Corpus

Dataset Summary

The Hausa VOA NER is a named entity recognition (NER) dataset for Hausa language based on the VOA Hausa news corpus.

Supported Tasks and Leaderboards

Languages

The language supported is Hausa.

Dataset Structure

Data Instances

A data point consists of sentences seperated by empty line and tab-seperated tokens and tags. {'id': '0', 'ner_tags': [B-PER, 0, 0, B-LOC, 0], 'tokens': ['Trump', 'ya', 'ce', 'Rasha', 'ma'] }

Data Fields

• id: id of the sample
• tokens: the tokens of the example text
• ner_tags: the NER tags of each token

The NER tags correspond to this list:

"O", "B-PER", "I-PER", "B-ORG", "I-ORG", "B-LOC", "I-LOC", "B-DATE", "I-DATE",

The NER tags have the same format as in the CoNLL shared task: a B denotes the first item of a phrase and an I any non-initial word. There are four types of phrases: person names (PER), organizations (ORG), locations (LOC) and dates & times (DATE). (O) is used for tokens not considered part of any named entity.

Data Splits

Training (1,014 sentences), validation (145 sentences) and test split (291 sentences)

Dataset Creation

Curation Rationale

The data was created to help introduce resources to new language - Hausa.
