Abstract
A relationship extracting apparatus acquires event information that indicates features of an event of interest, determine target duration based on one or more features of the event of interest, and extract one or more action-related relationships that exist during the target duration from object relationships information. The object relationship information indicates two or more action-related relationships between objects in association with time at which or during which the action-related relationship exists.
Claims20
A relationship extracting apparatus comprising:
- at least one memory that is configured to store instructions;
- and
- at least one processor that is configured to execute the instructions to:
- acquire event information that indicates one or more features of an event of interest;
- determine target duration based on the one or more features of the event of interest, the target duration including, as a part thereof, an event time at which or during which the event of interest occurs;
- and
- extract one or more action-related relationships that exist during the target duration from object relationships information, which indicates two or more action-related relationships between objects in association with time at which or during which the action-related relationship exists.
A relationship extracting method comprising:
- acquiring event information that indicates one or more features of an event of interest;
- determining target duration based on the one or more features of the event of interest, the target duration including, as a part thereof, an event time at which or during which the event of interest occurs;
- and
- extracting one or more action-related relationships that exist during the target duration from object relationships information, which indicates two or more action-related relationships between objects in association with time at which or during which the action-related relationship exists.
A non-transitory computer-readable storage medium storing a program that causes a computer to execute:
- acquiring event information that indicates one or more features of an event of interest;
- determining target duration based on the one or more features of the event of interest, the target duration including, as a part thereof, an event time at which or during which the event of interest occurs;
- and
- extracting one or more action-related relationships that exist during the target duration from object relationships information, which indicates two or more action-related relationships between objects in association with time at which or during which the action-related relationship exists.
