“…Even if our sample size is very small, the results point in the same direction as previous studies, e.g. [5] compared tags with the page text and back and forward link page text, and found that in 20% of the cases tags provided search data not provided by other sources.…”

“…It is interesting that, especially in a multilingual context, such a high percentage of overlap exists between natural language and controlled vocabularies. In [5] authors report that the folksonomy set overlapped with the indexer set on average 19.5%. Table 4 shows that 58% of all users had clicked on tags while searching for resources, whereas 42% never used tags.…”

“…Vander Wal [2] observed that tagging could be used to compensate for missing terms in a taxonomy and Lin et al [3] and Al-Khalifa et al [4] explored the overlap of tags with controlled vocabularies and automatic indexing. Sen et al have studied the quality of tags and tagclouds in [5], Farooq et al [6] focus on folksonomies adding intellectual value to a tagging system, whereas Heymann et al [7] observe that tags are present in the page text of 50% of annotated pages and in 16% of the titles.…”

Abstract. In this study, over a period of six months, we gathered empirical data from more than 200 users on a learning resource portal with a social bookmarking and tagging feature. Our aim was to study the interrelation of conventional metadata and social tags on the one hand, and their interaction with the environment, which can be understood as the repository, its resources and all stakeholders that included the managers, metadata indexers and the whole community of users. We found an interplay between tags and descriptors and showed how tags can enrich and add value to multilingual controlled vocabularies in various ways. We also showed that, even if many tags can be seen as redundant in terms of the existing LOM, some of them can become a useful source of metadata for repository owners, and help them better understand users' needs and demands.

“…We measured tag quality using collective opinion of the user community. We were able to do this because MovieLens includes an interface that lets users rate tags as "thumbs up" (good tag, I agree) or "thumbs down" (poor tag, I don't agree) for a tag [16]. Over 90% of tags in MovieLens have been rated.…”

Recommender systems try to address the "new user problem" by quickly and painlessly learning user preferences so that users can begin receiving recommendations as soon as possible. We take an expanded perspective on the new user experience, seeing it as an opportunity to elicit valuable contributions to the community and shape subsequent user behavior. We conducted a field experiment in MovieLens where we imposed additional work on new users: not only did they have to rate movies, they also had to enter varying numbers of tags. While requiring more work led to fewer users completing the entry process, the benefits were significant: the remaining users produced a large volume of tags initially, and continued to enter tags at a much higher rate than a control group. Further, their rating behavior was not depressed. Our results suggest that careful design of the initial user experience can lead to significant benefits for an online community.
