Access to the web containing UGC is known to follow a heavy-tailed distribution. For example, the top 10% of the videos in a normal video-on-demand...

In this paper, an error analysis based on boundary error popularity (frequency) including semantic boundary categorization is applied in the context of the news story segmentation task from TRECVID. Clusters of systems were defined based on the input resources they used including video, audio and automatic speech recognition.
