/Presentation :"Google News automatically groups news tories with similar content and places them based on algorithmic results into clusters. In Newsmap, the size of each cell is determined by the amount of related articles that exist inside each news cluster that the Google News Aggregator presents. In that way users can quickly identify which news stories have been given the most coverage, viewing the map by region, topic or time. Through that process it still accentuates the importance of a given article.Newsmap also allows to compare the news landscape among several countries, making it possible to differentiate which countries give more coverage to, for example, more national news than international or sports rather than businessCurrently, the internet presents a highly disorganized collage of information. Many of us are working in an information-soaked world. There is too much of everything. We are subject everywhere to a sensory overload of images, bombarded with information; in magazines and advertisements, on TV, radio, in the cityscape. The internet is a wonderful communication tool, but day after day we find ourselves constantly dealing with information overload. Today, the internet presents a new challenge, the wide and unregulated distribution of information requires new visual paradigms to organize, simplify and analyze large amounts of data. New user interface challenges are arising to deal with all that overwhelming quantity of information."Website (source) : http://newsmap.jp/Voir aussi :http://www.multimedialab.be/cours/interfaces/visualisation.htm /
