BUTT, Sabur et al. Transformer-Based Extractive Social Media Question Answering on TweetQA. Comp. y Sist. [online]. 2021, vol.25, n.1, pp.23-32. Epub 13-Set-2021. ISSN 2007-9737. https://doi.org/10.13053/cys-25-1-3897.
The paper tackles the problem of question answering on social media data through an extractive approach. The task of question answering consists in obtaining an answer from the context given the context and a question. Our approach uses transformer models, which were fine-tuned on SQuAD. Usually, SQuAD is used for extractive question answering for comparing the results with human judgments in social media TweetQA dataset. Our experiments on multiple transformer models indicate the importance of application of pre-processing in the question answering on social media data and elucidates that extractive question answering fine-tuning even on other type of data can significantly improve the results reducing the gap with human evaluation. We use ROUGE, METEOR, and BLEU metrics.
