Abstract. Tagging has been popularized by Web 2.0 sites as a way to describe resources. Typically, tagging has been done in an explicit way in which users directly describe with tags the resources in which they are interested. However in today’s ubiquitous computing environments, it is possible to implicitly tag resources. This paper: (1) introduces the concept of explicit and implicit tagging for user models in two domains: Web 2.0 and mobile phone usage, respectively; and (2) compares the characteristics of both tagging mechanisms. Results indicate that the use of tags in both approaches is very similar, whereas the statistical characteristics of the common-interest networks are different.
