A method and system for pronoun disambiguation adapts or learns from evaluating input by the user. The system stores pronoun information relating to pronoun usage for people, entities, and things that a user can use a pronoun to refer to in interacting with the system. The pronoun information is used by the system in a process that interprets the meaning of the pronoun in the context of the interaction with the user. The system and method include matching the pronoun reference input by the user to the likely person or thing based upon an evolving pronoun preference associated with the person, entity or thing. During each interaction, the system and method permit the user to verify that the system interpreted the pronoun as referring to the correct person, entity or thing and modifies the stored pronoun information to reflect the verified usage. The system and method can select pronoun preferences when a user adds an entry into their address book by searching for information that can indicate the proper pronoun preference for a given entry. The pronoun preference can be selected based upon information in the user's address book and/or other sources of pronoun information such as other users' address books and system databases.
