A meaning vector calculation part 32 calculates a word meaning vector for each of the plural word division candidates, based on the plural word division candidates. A synonym pair acquisition part 34 selects word division candidates in which, meaning similarity calculated based on the meaning vector is equal to or higher than a threshold, and a sound similarity distance calculated based on reading of the word is equal to or lower than a threshold, for each of the word division candidates which are the normal notation words, from the word division candidates, then, acquires a pair of the word division candidate being the normal notation word, and the selected word division candidate as a synonym pair.SELECTED DRAWING: Figure 1 |
