Rated Tags: Adding Rating Capability to Collaborative Tagging

Collaborative tagging is a popular way to organize content. But sometimes it is also used as a way to express opinions, which is normally done through rating- or text review systems. This paper will demonstrate that there is a gap between rating- and text review systems, that limits the ability of users to find the desired item. A novel concept based on collaborative tagging is presented, which is designed to bridge this gap. This concept, named Rated Tags, uses a hybrid approach to combine tagging-, rating- and review functionality. A key element of Rated Tags is the combination of a traditional user generated tag and a 5-star rating scale. Such a tag is called rated tag. We will discuss the design and the challenges of Rated Tags in detail and demonstrate its application based on a prototype. Furthermore we will show that similar related works suffer from an ambiguity problem, which was avoided in Rated Tags.
