Raining Words

Try It

Description

`Raining Words' is designed to display high frequency words such that high frequency words are rendered larger and move more slowly than words with lower frequencies. The source HTML document (URL or local file) is read and reduced to the contents of an HTML element (e.g. <body>). It is then filtered using a stop-word list. The resulting text is then scanned for the top 20 high frequency words.

Note: The input text must be in HTML format. Otherwise, it will cause file type not match error.

Issues

This tool requires the JRE (v1.4.2 and up) in order to work properly.* This is likely to cause problems with OS X users using browsers other than Safari. By default, Firefox and other OS X web browsers use an older version of the JRE which is incompatible with this tool.* There is a solution that allows Firefox to use JRE 1.4.2+ which can be found here. Unfortunately this fix does not seem to work for the OS X version of Internet Explorer.

* This is only relevant if the desired output is Java.

Pseudocode

  • Obtain text string by URL which points to an HTMLtext
  • Extract text based on user specified HTML tag name
  • Tokenize text into words using taporware tokenizer
  • Sort and count words with the capitalization ignored
  • Extract words based on user specified criteria if necessary
  • Get th top 20 high frequency words and generate a java applet

Ways of Using

  • Enter a valid URL in the URL field
  • Enter the HTML element name in the corresponding field in which you want to investigate the text
  • Select which list you want to get and enter the corresponding text if necessary
  • If you want the results displayed in the same window with taporware interface, uncheck the check box - "Open results in new window"
  • Finally, click the "Submit" button
