You Make me Feel like a Natural Question: Training QA Systems on Transformed Trivia Questions

Training question answering (QA) and information retrieval systems for web queries require large, expensive datasets that are difficult to annotate and time-consuming to gather.Moreover, while natural datasets of informationseeking questions are often prone to ambiguity or ill-formed, there are troves of freely available, carefully crafted question datasets for many languages.Thus, we automatically generate shorter, information-seeking questions, resembling web queries in the style of the Natural Questions (NQ) dataset from longer trivia data.Training a QA system on these transformed questions is a viable strategy for alternating to more expensive training setups showing the F1 score difference of less than six points and contrasting the final systems. 1
