1. A computer-implemented method for building a dynamic classification dictionary, the method comprising: analyzing author-generated classification information regarding a document with a content analysis server and assigning a set of first taxonomic nouns to characterize the document based upon the author-generated classification information; examining a user-generated tag from a client computer characterizing a portion of the document and assigning a set of second taxonomic nouns to characterize the document based upon the user-generated tag characterization; identifying a search term that resulted in the user accessing the document from a content provider site server and assigning a set of third taxonomic nouns to characterize the document based upon the search term; evaluating attributes related to the manner in which the user accesses the document from the content provider site server and assigning a set of fourth taxonomic nouns to characterize the document based upon the attributes related to the manner in which the document was accessed; processing the document with a content analysis server to extract a set of fifth taxonomic nouns to characterize the document based upon a predetermined pattern rule; aggregating the set of first taxonomic nouns, the set of second taxonomic nouns, the set of third taxonomic nouns, the set of fourth taxonomic nouns, and the set of fifth taxonomic nouns into a composite set of taxonomic nouns with a dictionary builder server; and building a dynamic classification dictionary with the dictionary builder server by storing the composite set of taxonomic nouns.
