PURPOSE: A Japanese adnominal postposition recovery method is provided to translate Korean text into more natural Japanese text by processing the Japanese adnominal postposition. CONSTITUTION: The method comprises steps of obtaining a possibility of a certain noun appearance with an adnominal postposition by using combination force among words, statistical probability value obtained via a corpus learning when the noun makes a compound noun in the outer layer, and obtaining a possibility of two noun semantic code combination appearance with the adnominal postposition by using the combination force of the adnominal postposition according to a semantic relation, statistical probability value obtained via the corpus learning. The combination force among words includes pre-directional combination force and post-directional combination force. The pre-directional combination force is a probability that the adnominal postposition is inserted prior to the noun when the noun is a latter noun in the compound noun. The post-directional combination force is a probability that the adnominal postposition is inserted posterior to the noun when the noun is a former noun in the compound noun.
