Abstract

A keyword generation apparatus, comprises a vocabulary acquisition unit that acquires a keyword uttered by a first user; a first positional information acquisition unit that acquires first positional information including information representing a location at which the first user has uttered the keyword; a storage unit that stores the first positional information and the keyword in association with each other; a second positional information acquisition unit that acquires second positional information including information representing a current position of a second user; and an extraction unit that extracts a keyword unique to a locality in which the second user is positioned from the storage unit based on the second positional information.

First claim

What is claimed is:

1 . A keyword generation apparatus, comprising:
a vocabulary acquisition unit that acquires a keyword uttered by a first user; a first positional information acquisition unit that acquires first positional information including information representing a location at which the first user has uttered the keyword; a storage unit that stores the first positional information and the keyword in association with each other; a second positional information acquisition unit that acquires second positional information including information representing a current position of a second user; and an extraction unit that extracts a keyword unique to a locality in which the second user is positioned from the storage unit based on the second positional information.

2 . The keyword generation apparatus according to claim 1 , wherein
when there is a keyword which is uttered by the first user and of which an occurrence is higher in the locality in which the second user is positioned than in another locality, the extraction unit preferentially extracts the keyword.

3 . The keyword generation apparatus according to claim 1 , further comprising a unit that stores data representing preferences of the second user, wherein
the extraction unit extracts a keyword compatible with the preferences of the second user.

4 . The keyword generation apparatus according to claim 1 , wherein
the first positional information further includes information related to a movement direction of the first user, and the storage unit further associates the movement direction with the keyword and stores the associated movement direction and keyword.

5 . The keyword generation apparatus according to claim 4 , wherein
the second positional information further includes information related to a movement direction of the second user, and the extraction unit extracts the keyword further based on the movement direction of the second user.

6 . The keyword generation apparatus according to claim 1 , wherein
the first positional information further includes information related to a destination of the first user, and the storage unit further associates the destination with the keyword and stores the associated destination and keyword.

7 . The keyword generation apparatus according to claim 6 , wherein
the second positional information further includes information related to a destination of the second user, and the extraction unit extracts the keyword further based on the destination of the second user.

8 . A dialogue text generation system, comprising:
the keyword generation apparatus according to claim 1 ; and a dialogue text generation apparatus that generates a dialogue text to be provided to a user, based on a keyword acquired by the keyword generation apparatus.

9 . A keyword generation apparatus, comprising:
a first acquisition unit that acquires keyword data associating a keyword uttered by a first user and first positional information including information representing a location at which the first user has uttered the keyword with each other; a second acquisition unit that acquires second positional information including information representing a current position of a second user; and an extraction unit that extracts a keyword unique to a locality in which the second user is positioned from the keyword data based on the second positional information.

10 . A keyword generation method, comprising the steps of:
acquiring a keyword uttered by a first user; acquiring first positional information including information representing a location at which the first user has uttered the keyword; storing the first positional information and the keyword in association with each other in a storage unit; acquiring second positional information including information representing a current position of a second user; and extracting a keyword unique to a locality in which the second user is positioned from the storage unit based on the second positional information.
