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_textis the source sentencetgt_textis the target sentencecosine_scoreis 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)
