Written by Matt Biddulph del.icio.us tag stemmer, uses Porter stemming to show where you’ve made different del.icio.us tags with the same English word stem. You can use it to help clean up your personal fauxonomy.
The Porter stemming algorithm (or ‘Porter stemmer’) is a process for removing the commoner morphological and inflexional endings from words in English. Its main use is as part of a term normalisation process that is usually done when setting up Information Retrieval systems.
Update: Matt now has a intro page to the Tag Stemmer up : Stemming tags, and one website to the tune of another, with a notes & Links to demo expriement: “del.icio.us seamlessly embedded in the BBC Radio 3 website“. A kind of “Tag Explorer” : this page has been tagged with X & Y, see other pages you have tagged with X, see pages other have tagged with X.
