Title Network News Comment Research—the correlation between news factors and comment elements
Abstract
With the rapid development of network news and comments, the correlation between news factors and comment elements is increasingly becoming a project worthy of research. Based on news factors and comment elements, this paper discusses the correlation between network news and its comments in terms of time, location and theme. From the perspective of comment elements, this paper makes theoretical assumptions on the correlation between comment bursting point and news publish time, reviewer’s geographical distribution and news locality, as well as comment theme and news theme. Finally, it comes to a conclusion through empirical analysis verifying the correctness of those assumptions, so that to provide reference and guidance for the future development of network news and comments.
