Clustering

A technique the search engines use to group different pages from the same domain in their search results pages. Without clustering, the top spots for certain search terms are often completely dominated by one site. Clusters usually consist of one or two pages from one domain with a link that says something like “More results from pandecta.com”. The term differs from terms like classification, taxonomy building, tagging, etc. in that it is fully automated. Further human intervention is not needed.
