Abstract

Most Web 2.0 applications let users associate textual information with multimedia content. Despite each application's lack of editorial control, these textual features are still the primary source of information for many relevant services such as search. Previous efforts in assessing the quality of these features target, mostly, single applications, and mainly focus on tags, thus neglecting the potential of other features. The current study assesses and compares the quality of four textual features (title, tags, description, and comments) for supporting information services using data from YouTube, YahooVideo, and LastFM.
