摘要:
A cross-language relevance determination device includes: a database that stores data including a plurality of sentences; a relation determination unit that calculates the number of times a specific word has appeared between input two words in the database, and that determines whether the two words are conceptually in a hierarchical relation or in a parallel relation on the basis of a position of a coordinate having the calculated number of times as a coordinate value in an imaginary space having an axis that represents the number of appearances of the specific word.
