All Finished

Well I’m all finished.  Handed in my report, I’m pleased with all I’ve accomplished through this project.

Here is the Abstract for the report:

Through discussion and analysis of current research in collaborative tagging systems, an emerging area of research was discovered, improving accessibility and search of visual resources through tagging.  Of particular interest were two tagging projects ESP Game and Steve.Museum, where users were encouraged to tag images to improve accessibility and search of images.  VideoTag extends this research by harnessing the user motivations of Play and Competition to increase and improve the meta data of a selection of YouTube videos through tagging. 

The VideoTag tagging experiment consisted of a one player game where users were encouraged to tag a selection of sixty carefully chosen, funny or interesting YouTube Videos.  The videos were separated over five difficulty levels.  Gameplay was carefully planned in order to encourage users to tag the videos more descriptively, using tags of a subordinate rather than basic cognitive level.  The experiment was uncontrolled with random users being attracted to the game through promotion on various Web 2.0 sites.

Analysis of the results focused on whether a game environment is beneficial to encouraging users to tag videos.  Quantitative methods of analysis found VideoTag to be successful at increasing the amount of tags per video compared to YouTube.   A long tail effect was found to present in the tag data which allowed for qualitative analysis of the quality of the tags entered based on their cognitive level.  

As only a small selection of videos were used, tag data generated by the VideoTag experiment is not sufficient to test whether the data can improve search for those selected videos, or create descriptions to improve accessibility for visually impaired users.  Analysis and evaluation does discuss how VideoTag proves as a concept, game based tagging could be used to improve accessibility and search and there is scope for future research .
