Why we have records -- surrogates for the desired object
Build indexes. The better the surrogate, the better the results
OCLC, Z39.50 gets us LC and OhioLINK, Biblios.net, Open Library
These are all Human-Generated records
“Catalogers” -> “Descriptionists”
Use taxonomies and ontologies to create the surrogate records
“Metadata” -- what is known -- to “Data” what is sought
Google’s experiment in computational analytics
Relying on the text of the item itself to be the descriptive surrogate; Examines every word
Amazon’s “Key Phrases” techniques -- Capitalized Phrases and Statistically Impossible Phrases form the surrogate
Which is better?
