To allow generating word vectors in an accurate manner with no need of restricting vocabularies in a word vector collection.SOLUTION: Disclosed is a vector generation device 10 for generating vectors expressing an input sentence P, and when a defined sentence consideration context coding section 280 generates vector series expressing the input sentence P based on vectors against each word included in the input sentence P, it generates the vector series expressing the input sentence P using a defined sentence Dof an index word y, as to a word which is the index word stored in a dictionary DB from amongst the words included in the input sentence P, based on the dictionary DB 230 in which a pair of an index word y and a defined sentence Dwhich is a sentence to define the index word y is stored.SELECTED DRAWING: Figure 1
