13. At least one non-transitory computer-readable medium storing computer-readable instructions that, when executed by one or more computing devices, cause at least one of the one or more computing devices to: generate a set of demographic nouns corresponding to a user based on one or more of: registration information provided by the user or data derived from an analysis of a connection of the user; generate one or more sets of taxonomic nouns corresponding to the user, wherein the one or more sets of taxonomic nouns comprise one or more of: a set of first taxonomic nouns based upon classification information generated by an author of at least one document in a set of documents; a set of second taxonomic nouns based upon one or more user-generated tags characterizing at least a portion of at least one document in the set of documents; a set of third taxonomic based upon one or more search terms utilized by the user to access at least one document in the set of documents; or a set of fourth taxonomic nouns based upon the attributes related to a method of access of at least one document in the set of documents; generate a set of fifth taxonomic nouns corresponding to the user by processing at least one document in the set of documents based upon one or more pattern rules and a dictionary of known terms, wherein the one or more pattern rules specify a method of extracting terms from the at least one document; aggregate at least one of the one or more sets of taxonomic nouns with the set of fifth taxonomic nouns into a composite set of taxonomic nouns corresponding to the user; and generate a value index corresponding to the user based at least in part on a comparison between: a quantity of nouns in the set of demographic nouns corresponding to the user and the composite set of taxonomic nouns corresponding to the user, and one or more quantities of nouns in one or more sets of demographic nouns corresponding to one or more other users and one or more composite sets of taxonomic nouns corresponding to the one or more other users.
17. The at least one non-transitory computer-readable medium of claim 13 , wherein the instructions that, when executed by at least one of the one or more computing devices, cause at least one of the one or more computing devices to generate a set of fifth taxonomic nouns by processing at least one document in the set of documents based upon one or more pattern rules and a dictionary of known terms further cause at least one of the one or more computing devices to: apply the one or more pattern rules to free form text of the at least one document to extract one or more terms; compare the one or more terms to the dictionary of known terms to identify matching terms; and assign the matching terms to the set of fifth taxonomic nouns.
