What is TagCrowd?

“TagCrowd is a web application for visualizing word frequencies in any text by creating what is popularly known as a word cloud, text cloud or tag cloud.

It was created by Daniel Steinbock, a doctoral student in Design and Education at Stanford University.

A word cloud is a beautiful, informative image that communicates much in a single glance. TagCrowd specializes in making your word clouds easy to read, analyze and compare, for a variety of useful purposes:

  • as topic summaries for speeches and written works
  • as blog tool or website analysis for search engine optimization (SEO)
  • for visual analysis of qualitative data
  • as brand clouds that let companies see how they are perceived by the world
  • for data mining a text corpus
  • for helping writers and students reflect on their work
  • as name tags for conferences, cocktail parties or wherever new collaborations start
  • as resumes in a single glance
  • as visual poetry

The list goes on and continues to grow.”

A sample TagCrowd which compares the State of the Union Address, 2002 -v- 2011 gives you an idea of the uses for this powerful application:-

 

TagCrowd utilises Porter Stemming Algorithm “a stemmer” (invented by Dr. Martin Porter 1980)  which is the de facto standard process of reducing words to their stem (or root) to find the frequency of words.

I particularly like TagCrowd because it enables you to link to a URL to extract text or to upload a file or to copy/paste your text, allowing you choices about how to enter your text.  In fact you can copy/paste up to 6Mb of text and you can also join words together by inserting a tilde character to keep, for example, place names as one entry.

As someone who loves words as well as visual imagery, this is a perfect tool.
