Improving Tag-Clouds as Visual Information Retrieval InterfacesTagging-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.
Twine Launches A Smarter Way To Organize Your Online LifeOn the surface, Twine is a place to organize information you find or create on the Web-bookmarks, notes, videos, photos,contacts, tasks. You can also share that information with a private group or publicly. Once you ingest in all the information you want to organize, Twine applies a semantic analysis to it that creates tags for each document or video or photo.Erick Schonfeld
