The Structure of Collaborative Tagging Systems
Collaborative tagging describes the process by which many users add metadata in the form of keywords to shared content. Recently, collaborative tagging has grown in popularity on the web, on sites that allow users to tag bookmarks, photographs and other content. In this paper we analyze the structure of collaborative tagging systems as well as their dynamical aspects. Specifically, we discovered regularities in user activity, tag frequencies, kinds of tags used, bursts of popularity in bookmarking and a remarkable stability in the relative proportions of tags within a given url. We also present a dynamical model of collaborative tagging that predicts these stable patterns and relates them to imitation and shared knowledge.

Improving Tag-Clouds as Visual Information Retrieval Interfaces
Tagging-based systems enable users to categorize web resources by means of tags (freely chosen keywords), in order to re-finding these resources later. Tagging is implicitly also a social indexing process, since users share their tags and resources, constructing a social tag index, so-called folksonomy. At the same time of tagging-based system, has been popularised an interface model for visual information retrieval known as Tag-Cloud. In this model, the most frequently used tags are displayed in alphabetical order. This paper presents a novel approach to Tag-Cloud’s tags selection, and proposes the use of clustering algorithms for visual layout, with the aim of improve browsing experience. The results suggest that presented approach reduces the semantic density of tag set, and improves the visual consistency of Tag-Cloud layout.

The ESP Game
The ESP Game is a two-player game. Each time you play you are randomly paired with another player whose identity you don't know. You can't communicate with your partner, and the only thing you have in common with them is that you can both see the same image. The goal is to guess what your partner is typing on each image. Once you both type the same word(s), you get a new image. Each time you type a word or phrase, you must press enter on your keyboard to submit it to the game. You can type as many guesses as you want, and as soon as a single guess of yours is equal to a guess that your partner has made, you get a new image. You have two and a half minutes to agree on 15 images.
Some images have taboo words, which you can't use; nor can you use any plural, singular, or word related to a taboo word. If one of the taboos for an image is the name of a color, you cannot use any other color as a guess. If you feel that an image is too hard, you can ask to pass by clicking the yellow pass button on the lower right corner. Clicking the button will generate a message on your partner's screen, letting them know that you want to pass. You cannot pass on an image until both you and your partner have hit the pass button.
