Title
Natural language interface for an expert system
Source
Expert systems. 15(1998) no.4, S.233-239
Year
1998
Abstract
Presents a complete analysis of the underlying principles of natural language interfaces from the screen manager to the parser / understander. The main focus is on the design and development of a subsystem for understanding natural language input in an expert system. Considers that fast response time and user friendliness are the most important considerations in the design. The screen manager provides an easy editing capability for users and the spelling correction system can detect most spelling errors and correct them automatically, quickly and effectively. The Lexical Functional Grammar (LFG) parser and the understander are designed to handle most types of simple sentences, fragments, and ellipses
