Abstract
A system for changing a natural language sentence input by a user. The sentence expresses an operation specification which is translated to an operation specification command in a machine language for an operation specification object such as database. The system has a function to define specific items necessary for changing the natural language input sentence to the operation specification command without forcing the user to decide complicated definitions related to the operation specification object. The system refers to an operation specification object information table which stores at least one of the following acquired from the user: (1) A unit word or an interrogative word (phrase) with respect to each of the items in the database; (2) An explanatory sentence with respect to each of the items in the database; and (3) An item pair which is specifiable as a join condition of each of the items in the database.
