Tag clouds – data visualisation

A tag cloud or word cloud is a visual representation of the relative word content of a website or feed. The word cloud displayed in this post is computer-generated every 6 hours to display the most frequently appearing words in headlines concerned with the ‘environment’ from 12 international news organisations. Each organisation is likely to have some bias in its reporting of environment-related news but word cloud analysis helps reveal the predominantly important issues or stories of the day. Another simple word cloud is implemented at Eurovision Song Contest Voting, where over 100 sites are polled every 30 minutes. These are simple implementations of a much larger project we are currently involved with.
