### Dataset Summary |
|
|
|
MasakhaNER is the first large publicly available high-quality dataset for named entity recognition (NER) in ten African languages. |
|
|
|
Named entities are phrases that contain the names of persons, organizations, locations, times and quantities. Example: |
|
|
|
[PER Wolff] , currently a journalist in [LOC Argentina] , played with [PER Del Bosque] in the final years of the seventies in [ORG Real Madrid] . |
|
|
|
MasakhaNER is a named entity dataset consisting of PER, ORG, LOC, and DATE entities annotated by Masakhane for ten African languages: |
|
- Amharic |
|
- Hausa |
|
- Igbo |
|
- Kinyarwanda |
|
- Luganda |
|
- Luo |
|
- Nigerian-Pidgin |
|
- Swahili |
|
- Wolof |
|
- Yoruba |
|
|
|
The train/validation/test sets are available for all the ten languages. |
|
|
|
For more details see https://arxiv.org/abs/2103.11811 |
|
|
|
|
|
### Supported Tasks and Leaderboards |
|
|
|
[More Information Needed] |
|
|
|
- `named-entity-recognition`: The performance in this task is measured with [F1](https://huggingface.co/metrics/f1) (higher is better). A named entity is correct only if it is an exact match of the corresponding entity in the data. |
|
|
|
### Languages |
|
|
|
There are ten languages available : |
|
- Amharic (amh) |
|
- Hausa (hau) |
|
- Igbo (ibo) |
|
- Kinyarwanda (kin) |
|
- Luganda (kin) |
|
- Luo (luo) |
|
- Nigerian-Pidgin (pcm) |
|
- Swahili (swa) |
|
- Wolof (wol) |
|
- Yoruba (yor) |
|
|
|
## Dataset Structure |
|
|
|
### Data Instances |
|
|
|
The examples look like this for Yorùbá: |
|
|
|
``` |
|
from datasets import load_dataset |
|
data = load_dataset('masakhaner', 'yor') |
|
|
|
# Please, specify the language code |
|
|
|
# A data point consists of sentences seperated by empty line and tab-seperated tokens and tags. |
|
{'id': '0', |
|
'ner_tags': [B-DATE, I-DATE, 0, 0, 0, 0, 0, B-PER, I-PER, I-PER, O, O, O, O], |
|
'tokens': ['Wákàtí', 'méje', 'ti', 'ré', 'kọjá', 'lọ', 'tí', 'Luis', 'Carlos', 'Díaz', 'ti', 'di', 'awati', '.'] |
|
} |
|
``` |
|
|
|
### 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", |
|
``` |
|
|
|
In the NER tags, 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 & time (DATE). |
|
|
|
It is assumed that named entities are non-recursive and non-overlapping. In case a named entity is embedded in another named entity usually, only the top level entity is marked. |
|
|
|
### Data Splits |
|
|
|
For all languages, there are three splits. |
|
|
|
The original splits were named `train`, `dev` and `test` and they correspond to the `train`, `validation` and `test` splits. |
|
|
|
The splits have the following sizes : |
|
|
|
| Language | train | validation | test | |
|
|-----------------|------:|-----------:|-----:| |
|
| Amharic | 1750 | 250 | 500 | |
|
| Hausa | 1903 | 272 | 545 | |
|
| Igbo | 2233 | 319 | 638 | |
|
| Kinyarwanda | 2110 | 301 | 604 | |
|
| Luganda | 2003 | 200 | 401 | |
|
| Luo | 644 | 92 | 185 | |
|
| Nigerian-Pidgin | 2100 | 300 | 600 | |
|
| Swahili | 2104 | 300 | 602 | |
|
| Wolof | 1871 | 267 | 536 | |
|
| Yoruba | 2124 | 303 | 608 | |
|
|
|
## Dataset Creation |
|
|
|
### Curation Rationale |
|
|
|
The dataset was introduced to introduce new resources to ten languages that were under-served for natural language processing. |
|
|
|
[More Information Needed] |
|
|
|
### Source Data |
|
|
|
The source of the data is from the news domain, details can be found here https://arxiv.org/abs/2103.11811 |
|
|
|
#### Initial Data Collection and Normalization |
|
|
|
The articles were word-tokenized, information on the exact pre-processing pipeline is unavailable. |
|
|
|
#### Who are the source language producers? |
|
|
|
The source language was produced by journalists and writers employed by the news agency and newspaper mentioned above. |
|
|
|
### Annotations |
|
|
|
#### Annotation process |
|
|
|
Details can be found here https://arxiv.org/abs/2103.11811 |
|
|
|
#### Who are the annotators? |
|
|
|
Annotators were recruited from [Masakhane](https://www.masakhane.io/) |
|
|
|
### Personal and Sensitive Information |
|
|
|
The data is sourced from newspaper source and only contains mentions of public figures or individuals |
