1. A method of interacting with a user on a computer system,
the method comprising:
interacting with the user to identify an entity that the user does
not want;
setting an anti-entity value based on the identified entity without
setting values for entities that were not presented to the user while
interacting with the user;
using the anti-entity value to clarify ambiguous input from the
user by reducing a likelihood that the entity represented by the anti-
entity value will be considered as having been referenced in the
ambiguous input.
15. A computer-readable medium having computer-executable
instructions for performing steps comprising:
receiving an indication that a user wants to exclude an item from
consideration without receiving an indication that a user has selected
an item;
setting a value to reduce the likelihood that ambiguous input is
interpreted as including a reference to the item;
providing a response to the user;
after providing the response, receiving ambiguous input that can
be interpreted as having a reference to the item; and
accessing the value to determine how to interpret the ambiguous
input.
