Task: Question Understanding
Input (English): In this section we present two datasets used in our experiments: The NowThisNews dataset, collected for the purpose of this paper, and The BreakingNews dataset BIBREF4 , publicly available dataset of news articles.

contains 4090 posts with associated videos from NowThisNews Facebook page collected between 07/2015 and 07/2016. For each post we collected its title and the number of views of the corresponding video, which we consider our popularity metric. Due to a fairly lengthy data collection process, we decided to normalize our data by first grouping posts according to their publication month and then labeling the posts for which the popularity metric exceeds the median monthly value as popular, the remaining part as unpopular. 
 Question: Where do they obtain the news videos from?
Output (English): Extractive
