The use of ‘tag clouds’ in text presentation/analysis/indexing?

Marcia Zeng posted today the following message to the NKOS (Networked Knowledge Organization Systems) list:

    Everyone knows about the ‘tag cloud’ approach when showing popular tags. How about using this same idea for presenting keywords in documents and making a dynamic cloud which matches a particular event? Here are some examples I found interesting.

    The tag cloud shows the popularity, frequency, and trends in the usages of words within speeches, official documents, declarations, and letters written by the Presidents of the US between 1776 – 2007 AD.

    Microsoft’s evolution, in keywords
    At both case, there is a timeline on the top. Move the slider around for a unique glimpse into the document of a particular time.
