Claim 8:
9. 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 partially omitted query by:
performing at least one of i) a syntax analysis such as a dependency analysis, ii) a phrase structure analysis of the query, or iii) a pattern matching based on a predetermined marker to determine a part to be omitted from the query,
setting a granularity of the part to be omitted from the query, and
omitting a part of the query,

use a neural network model to generate a restored query by restoring the partially omitted query using a word included in a prescribed lexical set, and
use a difference between the restored query and the query to update a parameter of the neural network model.
