1. A method for discovering terminology unique to a distinct subset of a general population, said terminology comprised of new terms as well as unique and obscure usages of previously known terms, said method comprising: a. analyzing a first collection of communications to identify at least one of: a source of communication and an instance of communication fit for consumption by said general population; b. accessing a database of communications, based on said at least one of: a source of communication and an instance of communication, either extracted from said first collection or obtained from said source of communication; c. creating a first usage dictionary, from said database of communications, said first usage dictionary comprising terms, definitions corresponding to term usages, and frequencies corresponding to term usage; d. creating a second usage dictionary from a second collection of communications intended for consumption by said distinct subset of said general population, said second usage dictionary comprising terms, definitions corresponding to term usages, and frequencies corresponding to term usage; e. comparing said second usage dictionary with said first usage dictionary to determine, for said first and second collections of communications: existence of terms not shared in common, differences in usage of terms shared in common, and disparities in frequencies of usages of terms shared in common; and f. establishing terminology unique to said distinct subset of said general population, based on said comparative differences between usage dictionaries.
