Abstract from the paper

Social tagging systems allow users to upload and assign keywords to digital resources. Thus a body of user annotated resources gradually evolves: Users can share resources, re-find their own resources or use the systems as search engines for items added by the whole user population. In this paper we want to contribute towards a better understanding of usage patterns within social tagging systems by presenting results from a survey of 142 users of the systems Flickr, Youtube, Delicious and Connotea. Data was gathered partly by using the Mechanical Turk service, and partly via an announcement on the Connotea blog. Our study reveals differences of user motivation and tag usage between systems. While resource sharing emerges as an all-embracing intra-system motivation, users differ with respect to social spheres of sharing. Based on our results which we integrated with earlier research from Cool and Belkin 2002, we propose a model of information behaviour in social tagging systems.

Summary

Social Tagging is easy

• Professional Indexing is costly and suffer from low coverage
• Non-textual media are hard to index
• Shorter cognitive process than categorization

Why people use tags

A MTurk user study (qualitative). Two motivation for tagging: (Results are same as the assumptions)

• Personal Information Management (Delicious, Connotea)
• Resource Sharing (Flickr, Youtube)

Social Tagging and Perceptions of IR

• Search other collections ( Youtube, Flickr)
• Tags perceived as helpful for IR (Youtube, Flickr)
• Search own collection (Delicious, Connotea)
