The Rating Game

This CGI script was written to go along with my May 1997 WebTechniques column Sifting the Wheat from the Chaff. It demonstrations a way of rating Web pages automatically for information content. To use it, enter a full URL in the text field below and press Rate. After some processing, the script will report a variety of rating indexes. Since some sites customize themselves according to browser, you can impersonate various browsers to see how the ratings change.

This script isn't fast, so be patient. In order minimize system load, the script currently only descends one level of links.

Explain the ratings.
