Introduction to classification

A Brief History of Classification by Christine Connors, TriviumRLG LLC (Jan 10)

Humans have been classifying for as long as they have used a written language. One of the earliest examples is Pinakes at the Library of Alexandra. This short history takes us up to Ranganathan's Colon Classification in the 1900s, and observes that the first enterprise use was by publishers of indexes. On the web we have seen the classification structures of the Yahoo directory and the Open Directory Project. Today, "Pattern matching is the basis for much of what occurs in these systems for rules based categorization."
