Abstract
A question generation device includes: generating means which uses a query and a relevant document including an answer to the query as input and, using a machine learning model having been learned in advance, generates a revised query in which a potentially defective portion of the query is supplemented with a word included in a prescribed lexical set.
Claims12
A question generation device, comprising:
- a processor;
- and
- a memory storing program instructions that cause the processor to use a query and a relevant document including an answer to the query as input and, using a machine learning model having been learned in advance, generate a revised query in which a potentially defective portion of the query is supplemented with a word included in a prescribed lexical set.
A question generation device, comprising:
- a processor;
- and
- a memory storing program instructions that cause the processor to use a query and a relevant document including an answer to the query as input to generate a defective query by omitting a part of the query, use a neural network model to generate a restored query by restoring the defective query using a word included in a prescribed lexical set, and use an error between the restored query and the query to update a parameter of the neural network model.
A question generation method performed by a computer, the method comprising using a query and a relevant document including an answer to the query as input and, using a machine learning model having been learned in advance, generating a revised query in which a potentially defective portion of the query is supplemented with a word included in a prescribed lexical set.
