Use ‘tag clouds’ to analyze documents

Tag Crowd is a site that lets you create tag clouds for any document. Tag clouds are those clusters of variously sized words you see on many blogs and on Web sites such as Flickr. Usually, they are used to display the labels attached to blog posts or images and their frequency. But Tag Crowd does something different — it uses tag clouds as tools for document analysis. Two obvious uses for this are:

  • Analyze your own writing to reduce repetition of words.
  • Analyze someone else’s writing to pinpoint key themes.

It is easy to use. Simply paste text or upload a document. Below is a tag cloud I created using the text of the Declaration of Independence.
