Base Claim:
1. An electronic apparatus comprising: a computer readable storage medium and program instructions stored on the computer readable storage medium; and a processor communicatively coupled to the computer readable storage medium and configured to execute the program instructions to perform a method comprising: receiving an input character string from a user; retrieving, in response to input of a character string by a user, conversion candidates associated with the input character string, each conversion candidate having a first rank, wherein the input character string is a mail address and each conversion candidate is a nickname or a name, wherein the first rank is based on a first count corresponding to a total number of users who transmitted mails to the mail address using each nickname or name, wherein the first rank is further based on a second count corresponding to a total number of mails transmitted to the mail address using each nickname or name by the user; displaying, when a plurality of the conversion candidates are present, the plurality of conversion candidates within a corresponding plurality of regions on a map, wherein conversion candidates that have a higher first count occupy larger regions on the map, wherein a first region associated with a conversion candidate having a highest first count comprises 50% of the map, wherein a second region associated with a conversion candidate having a second highest first count comprises 30% of the map, wherein a third region associated with a conversion candidate having a third highest first count comprises 20% of the map, and wherein the plurality of regions on the map are further colored with chroma ordered according to the second count; and displaying, in response to a user selecting a particular region of the plurality of regions on the map with a user input device, information associated with the conversion candidate corresponding to the particular selected region.

Claim 2:
2. The electronic apparatus of claim 1 , wherein the first rank is further based on a third count corresponding to a number of mails transmitted for a respective sender-receiver pair of mail addresses; wherein the first rank is further based on a fourth count corresponding to a number of mails transmitted by senders belonging to a same organization as the user; and wherein the first rank is further based on a fifth count corresponding to a number of branches in a tree structure representing an organizational hierarchy between an organization of the user and an organization of a second user associated with the input character string.
