constantly seek new ways to attract large shares of online attention by
keeping their users engaged. A common challenge is to identify which
aspects of online interaction influence user engagement the most. In this
article, through an analysis of a news article collection obtained from
Yahoo! News US, we demonstrate that news articles exhibit considerable
variation in terms of the sentimentality and polarity of their content,
depending on factors like news provider and genre. Moreover, through
a laboratory study, we observe the effect of sentimentality and polarity
of news and comments on a set of subjective and objective measures of
engagement. In particular, we show that attention, affect, and gaze differ
across news of varying interestingness. As part of our study, we also
explore methods that exploit the sentiments expressed in user comments
to reorder the lists of comments displayed in news pages. Our results
indicate that user engagement can be predicted if we account for the
sentimentality and polarity of the content, as well as other factors that
drive attention and inspire human curiosity},
