wordStats can analyze a block of text or an entire Web page, computing the most frequent word occurrence.
To prevent words like 'a', 'and', 'the', etc. to appear in the results, a list of stop words is provided with the plugin. Stop words for French and English are included.
wordStats most obvious usage is for tag extraction algorithms, but other usage scenarios like Twitter profile analysis, or Web page domain or category detection are not that far fetched.
