Abstract
A question answering system includes a dangerous operation determination unit configured to determine whether question-answer pair data includes a dangerous operation, and an answer sentence replacement unit configured to replace, when it is determined that the dangerous operation is included, an answer sentence including a description of the dangerous operation included in a document by a replaced answer sentence depending on a classification of the dangerous operation, to thereby create replaced question-answer pair data.
Claims14
A question answering system that prevent the question answering system from suggesting a dangerous operation to a questioner, the question answering system comprising:
- a memory;
- and
- a central processing unit (CPU) that is communicatively coupled to the memory, wherein the CPU is configured to:
- receive a question from the questioner,
- identify, based on the question, a question pattern and an answer pattern corresponding to the question pattern from a description included in a document and convert the question pattern and answer pattern identified to create question-answer pair data including a question sentence and an answer sentence;
- and
- replace the question-answer pair data by replaced question-answer pair data including the question sentence and a replaced answer sentence,
- wherein the replaced question-answer pair data is determined by determining whether the answer sentence of the question-answer pair data includes the dangerous operation, and
- replacing, when it is determined that the dangerous operation is included in the answer sentence, the answer sentence including a description of the dangerous operation by the replaced answer sentence depending on a classification of the dangerous operation, to thereby create the replaced question-answer pair data.
A non-transitory computer readable medium storing instructions for preventing a question answering system from suggesting a dangerous operation to a questioner, the instructions when executed by a central processing unit of the question answering system cause the question answering system to execute a method comprising:
- receiving a question from the questioner;
- identifying, based on the question, a question pattern and an answer pattern corresponding to the question pattern from a description included in a document and converting the question pattern and answer pattern identified to create question-answer pair data including a question sentence and an answer sentence;
- and
- replacing the question-answer pair data by replaced question-answer pair data including the question sentence and a replaced answer sentence,
- wherein the replaced question-answer pair data is determined by determining whether the answer sentence of the question-answer pair data includes the dangerous operation, and
- replacing, when it is determined that the dangerous operation is included in the answer sentence, the answer sentence including a description of the dangerous operation by the replaced answer sentence depending on a classification of the dangerous operation, to thereby create the replaced question-answer pair data.
A question answering method for preventing a question answering system from suggesting a dangerous operation to a questioner, the question answering method comprising:
- receiving a question from the questioner;
- identifying, based on the question, a question pattern and an answer pattern corresponding to the question pattern from a description included in a document and converting the question pattern and answer pattern identified to create question-answer pair data including a question sentence and an answer sentence;
- and
- replacing the question-answer pair data by replaced question-answer pair data including the question sentence and a replaced answer sentence,
- wherein the replaced question-answer pair data is determined by:
- determining whether the answer sentence of the question-answer pair data includes the dangerous operation, and
- replacing, when it is determined that the dangerous operation is included in the answer sentence, the answer sentence including a description of the dangerous operation by the replaced answer sentence depending on a classification of the dangerous operation, to thereby create the replaced question-answer pair data.
