Incorporating user motivations to design for video tagging

User video tagging can enhance the indexing of large collections of videos, or can provide the basis for personalizing output. However, before the benefits of tagging can be reaped, users must be motivated to provide videos with tags. This article describes a two-stage study that aimed at collecting the most important motivations for users to tag video material. First, focus groups with internet users were held to elicit all possible motivations to tag videos on the internet. Next, 125 persons ranked these motivations for two cases via an online survey and responded to statements that assessed their acceptance of personalized output, based on their tags. Motivations related to indexing appear to be far more important for people than motivations related to socializing or communication. Furthermore, people were moderately positive about personalized output, based on their tags. Finally, important user barriers to tagging are discussed.
