Abstract: | We aim to conduct a dialogue with a machine in a natural manner without having to learn an artificial language. With the goal of supplying a natural language interface to a variety of operating systems, we have developed a TURBO-PROLOG ®-based system called NLDOS that facilitates the communication with the well known operating system MS-DOS®. NLDOS is capable of understanding English requests, providing an automatic spelling correction facility, resolving ambiguity, and discovering and locating logical errors. © 1993 John Wiley & Sons, Inc. |
