Abstract

In this paper, we report on a study that explores the contribution of social tags, professional metadata and automatically generated metadata to the retrieval process. In this study, 194 participants tagged a total of 115 videos, while another 140 participants searched the video collection for answers to eight questions. The results show that in the current context, social tags yield effective retrieval process, whereas automatically generated metadata do not. To put this result in perspective, participants' search strategies were primarily guided by the search tasks, instead of metadata elements. We have found some evidence social tagging is effective, as the same terminology was used the retrieval process as in the process of assigning metadata.
