Amara Hub

DataTrust Africa: Speech Corpus of Public Radio Recordings from Northern Uganda

This is an open-access corpus of short clips of public radio content from Mega 100 FM, Q FM, Radio Pacis and Radio Rupiny in Northern Uganda. As of now, the online corpus has over 350 clips of recordings in English. We also hope to add finely-annotated transcripts to them. The dataset is for use in NLP research and non-commercial use. Upcoming datasets to look out for from Amara Hub are public radio recordings in other languages spoken in the region like Acholi, Lango, Lugbara and Akaramajong.

SI-NLI

SI-NLI (Slovene Natural Language Inference Dataset) contains 5,937 human-created Slovene sentence pairs (premise and hypothesis) that are manually labeled with the labels "entailment", "contradiction", and "neutral". We created the dataset using sentences that appear in the Slovenian reference corpus ccKres (http://hdl.handle.net/11356/1034). Annotators were tasked to modify the hypothesis in a candidate pair in a way that reflects one of the labels. The dataset is balanced since the annotators created three modifications (entailment, contradiction, neutral) for each candidate sentence pair. The dataset is split into train, validation, and test sets, with sizes of 4,392, 547, and 998. We used Slovenian pre-trained language models to create splits, thereby ensuring that difficult and easy instances are evenly distributed in all three subsets. The dataset is released in a tabular TSV format. The README.txt file contains a description of the attributes. Only the hypothesis and premise are given in the test set (i.e. no annotations) since SI-NLI is integrated into the Slovene evaluation framework SloBENCH (https://slobench.cjvt.si/). If you use the dataset to train your models, please consider submitting the test set predictions to SloBENCH to get the evaluation score and see how it compares to others.
