Exemplary embodiments include a name disambiguation method, including identifying a plurality of names of persons in text received in the computer system, each of the plurality of names including a start and an end position, a family name and a given name, for each of the plurality of names of persons in the text, retrieving personal identification information from a global directory as a candidate for a name match, retrieving personal identification information from a private directory as a candidate for the name match, comparing the private directory personal identification information with the global directory personal identification information, eliminating the personal identification information from the private directory, retrieving frequencies of communications associated with the personal identification information from the private directory and displaying related information for each of the plurality of names of persons in the text.
