Do you remember a website called newsmaps.com that disappeared around February 2002? Newsmaps was able to automatically organise collections of documents basing itself on the information that they contained. The result was visualised by means of a terrain map where the elevations corresponded to the most relevant words or items.Â
Newsmaps was based on technology developed years before at the Pacific Northwest National LaboratoryÂ called ThemeScape. Newsmaps gathered the most important news and distributed them in an attractive âtopographicâ map that you could interactively explore. You could find out what the world was talking about just at a glance.Â
Newsmaps, originally a product of Cartia.Inc was acquired by Aurigin, that changed the name of the product to Aureka. Currently it's used by Micropatents under the same name for exploring textual spaces built up of patents.
A similar idea was put into practice on March 30th 2004 also with a similar name. Newsmap is an on-line application that presents the most relevant news of the moment, extracted from the Google news aggregator. The technology that newsmap uses is none other than the well known treemaps (see articles 51 and 52).Â
Newsmap visually codes each piece of news using several visual variables.
Newsmap retains another of the most searched for qualities in information visualisation, that is embracing the focus of our attention without losing the context (seeing both the forest and the trees simultaneously or, more technically speaking, focus + context).
On the other hand, it's possible to filter the news by country so that you can see the aggregate of all of them or just the result generated in one country, for example USA or any of the 10 countries present. It's also possible to filter the news by its typology, for example searching for technological news in all or only in some of the countries.
Newsmap, that has won the Netvision 2004 award of Ars Electronica comes from the hard work of Marcos Weskamp and Dan Albritton whose objective is âto simply demonstrate visually the relationships between data and the unseen patterns in news media. It is not thought to display an unbiased view of the news, on the contrary it is thought to ironically accentuate the bias of itâ (see the explanation at the web).
Newsmaps and Newsmap are two attractive and possibly efficient ways (I don't know of any usability studies on them) of news visualisation or, for that matter, document visualisation. Their underlying technologies are well differentiated: ThemeScape and Treemaps, but the final result is a quick and intuitive exploration of the document space.
Newsmap is an example of the power of visualisation and shows how relatively simple technology can significantly contribute to easing the digestion of the cataract of information that falls on us daily.
