“The nature of meaning in the age of Google” a paper by my former professor, Terry Brooks.
“Google may index billions of Web pages, but it will never exhaust the store of meaning of the Web. The reason is that Google’s aggregation strategy is only one of many different strategies that could be applied to the semantic objects in public Web space. Hidden in the ‘dogs’ retrieval set of 14.5 million are special, singular, obscure, unpopular, etc., Web pages that await a different aggregation strategy that would expose their special meanings. To charge that Google has a bias against obscure websites… is to expect Google to be something other than Google. Google finds the common meanings. Many other meanings exist on the Web and await their aggregators.”
