Manual Tagging - limitations

Manual Tagging: “Ian Black of Autonomy says that the Auutonomy project head at Ford’s training department says “Metadata is for the birds” because his department generates 5 million new objects per month, too much for manual tagging. Autonomy wants to provide systems that push info to users without requiring them to interact with it beforehand.
Eric Bonabeau of Icosystem says that we tend to believe that the future is present in the mass of data and we just need to find it. But we use existing patterns to search the data, which can’t turn up new patterns. Humans are amazing pattern-detecting machines but we’re terrible at exploring alternatives.”
