PROBLEM TO BE SOLVED: To solve the problem that translation with high accuracy cannot be performed in a conventional case.SOLUTION: A model for allowing translation with high accuracy is learned by a learning device equipped with: a syntax analyzer which performs syntax analysis of a target language sentence which each of one or more translation sentences has, and acquires a binary tree of the target language sentence having one or more target language part structures; an original language element acquisition part which acquires one or more elements of an original language; an original language part structure acquisition part which acquires one or more original language part structures including a parent node having a phrase label and two child nodes having the phrase label or elements of the original language by using structures indicated by one or more target language part structures which the binary tree of the target language sentence has; a label giving part which gives rearrangement labels to the one or more original language part structures; a model construction part which constructs one or more syntax analysis models having probability information of appearance of labelled original language part structures by using one or more labelled original language part structures; and a storage part which stores the binary tree of the original language sentence having the one or more syntax analysis models.
