# About
The dataset was obtained from the South African government magazine Vuk'uzenzele, created by the [Government Communication and Information System (GCIS)](https://www.gcis.gov.za/). 
The original raw PDFS were obtatined from the [Vuk'uzenzele website](https://www.vukuzenzele.gov.za/).

The datasets contain government magazine editions in 11 languages, namely:

|  Language  | Code  |  Language  | Code |
|------------|-------|------------|-------|
| English    | (eng) | Sepedi     | (sep) |
| Afrikaans  | (afr) | Setswana   | (tsn) |
| isiNdebele | (nbl) | Siswati    | (ssw) |
| isiXhosa   | (xho) | Tshivenda  | (ven) |
| isiZulu    | (zul) | Xitstonga  | (tso) |
| Sesotho    | (nso) |


# Datasets
The datasets consist of pairwise sentence aligned data. There are 55 distinct datasets of paired sentences.
The data is obtained by comparing [LASER](https://github.com/facebookresearch/LASER) embeddings of sentence tokens between 2 languages. If the similarity is high, the sentences are deemed semantic equivalents of one another and the observation is outputted. 

Naming convention:  
The naming structure of the pairwise_sentence_aligned folder is `aligned-{src_lang_code}-{tgt_lang_code}.csv`.  
For example, `aligned-afr-zul.csv` is the aligned sentences between Afrikaans and isiZulu. 

The data is in .csv format and the columns are `src_text`,`tgt_text`,`cosine_score` where:  
- `src_text` is the source sentence
- `tgt_text` is the target sentence
- `cosine_score` is the cosine similarity score obtained by comparing the sentence embeddings, it ranges from 0 to 1

**Note:** The notion of source (src) and target (tgt) are only necessary for distinction between the languages used in the aligned pair, as the sentence semantics should be bidirectional. (hallo <-> sawubona)
