Abstract
A negative example degree calculation apparatus 10 is provided with a purpose inference unit 11 that infers a purpose for which a user used an item in the past from relational data specifying the item used by the user in the past and purpose information indicating a use purpose of the item by the user, and a negative example degree computation unit 12 that computes a negative example degree indicating a possibility of the item not being selected by the user, based on the inferred purpose and the purpose information.
Claims21
A negative example degree calculation apparatus comprising:
- a purpose inference unit configured to infer a purpose for which a user used an item in the past from relational data specifying the item used by the user in the past and purpose information indicating a use purpose of the item by the user;
- and
- a negative example degree computation unit configured to compute a negative example degree indicating a possibility of the item not being selected by the user, based on the inferred purpose and the purpose information.
A negative example degree calculation method comprising:
- inferring a purpose for which a user used an item in the past from relational data specifying the item used by the user in the past and purpose information indicating a use purpose of the item by the user;
- and
- computing a negative example degree indicating a possibility of the item not being selected by the user, based on the inferred purpose and the purpose information.
A non-transitory computer readable recording medium that includes a program recorded thereon, the program including instructions that cause a computer to carry out:
- inferring a purpose for which a user used an item in the past from relational data specifying the item used by the user in the past and purpose information indicating a use purpose of the item by the user;
- and
- computing a negative example degree indicating a possibility of the item not being selected by the user, based on the inferred purpose and the purpose information.
