Abstract
A question and answer device 100 that generates answer data in response to question data includes a question determination unit 10 that receives a predetermined question type into which a feature of the question data is classified and the passage data matching the question data, determines whether machine reading is necessary on the basis of the question type, sets the passage data as the answer data when determining that the machine reading is not necessary, and sets answer text data extracted from the passage data by the machine reading as the answer data on the basis of the question data and the passage data when determining that the machine reading is necessary.
Claims11
A question and answer device that generates answer data in response to question data,
- the question and answer device comprising:
- question determination circuitry that receives a predetermined question type into which a feature of the question data is classified and passage data that matches the question data, determines whether machine reading is necessary on a basis of the question type, sets the passage data as the answer data when determining that the machine reading is not necessary, and sets answer text data extracted from the passage data by the machine reading on a basis of the question data and the passage data when determining that the machine reading is necessary.
A question and answer method implemented by a question and answer device that generates answer data in response to question data,
- the question and answer method comprising:
- receiving a predetermined question type into which a feature of the question data is classified, and passage data that matches the question data;
- determining whether machine reading is necessary, on a basis of the question type;
