wordStats 介绍
The jQuery wordStats plugin tries to determine what a page is about by
computing the density of its keywords.
It uses a simple algorithm which adds a variable weight for each keyword
occurence, depending on its ‘position’ in the document.
There’s of course a system to exclude ‘stop words’ (frequent pronouns,
prepositions, adverbs and so on).
I use wordStats and jFeed to display a list of articles related to the
current document, seeRelated feeds
widget.
