Remember Northern Light? That was the search engine that did an amazing job of dynamically clustering search results into folders based on their topic or area. That same type of functionality is now open sourced at Carrot2. Jon Lehto, of Monster.com, who pointed this out to me, notes that Carrot2 ” builds categories from search results (configurable number), and the user doesn’t need to ‘own’ the search data.”

BTW, Northern Light is still around, although not for public Web searching. Instead “Northern Light provides strategic research portals to global organizations.”
