Abstract

We propose a novel support system for evaluating the trustworthiness of video clips on a video sharing Web site. Our system is used for analyzing comments, posted by users, of a video clip and generating visuals for aiding a user in judging if a video clip is trustworthy or not. Our system is used for representing the changes in the positive and negative levels of comments by generating two types of time-related graphs. One is related to playback time, and the other is related to the date of a posted comment. We realized the prototype system and discussed the capability of our system.
