ABSTRACT:
An input device (12) receives a natural language or conversational statement in the form of a character string (1). A processor (14) performs a natural language analysis (2) to convert the input natural language into a command language instruction for a computer program. A morphological analysis (3) compares words of the input character string with contents of a dictionary (10) to convert the input words into preselected words indicated by the dictionary which are output as another character string. In a semantic or syntax analysis (4; FIG. 9), one of the inputted and another character strings are analyzed to generate a corresponding chained functions structure (FIGS. 2, 3). From knowledge (FIG. 5, 7) described by the plurality of chained function structures and from rules stored in knowledge memory (11), a new character string is generated. If the new character string is in command language, the command is executed (7). If the new character string is not in command language, it is reanalyzed (8, 9) to generate yet another character string. In this manner, instructions can be input by a user in any of a multiplicity of national languages in conversational format and converted into appropriate command instructions for an executed computer program.
