About

The dataset was obtained from the South African government magazine Vuk'uzenzele, created by the Government Communication and Information System (GCIS). The original raw PDFS were obtatined from the Vuk'uzenzele website.

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)

Available pairings

The alignment direction is bidrectional, i.e. xho-zul is zul-xho

Datasets

The datasets consist of pairwise sentence aligned data. There are 55 distinct datasets of paired sentences. The data is obtained by comparing 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)
