A Questioning-Answering Program for Simple Kernel Sentences (QUE2).
Alexander, Bill
QUE2 is a recently devised, natural language, questioning-answering program written in LISP1-5. It deals in simple, kernel sentences and employs the theory that the semantic content of a sentence is the set of relationships between conceptual objects (represented by the words in it), which the sentence and its structure imply. The data base of the program is an arbitrary list of simple kernel sentences. The lexicon is a list of pairs; the first element is the word itself, and the second element is its definition--the first element a relation and the second a list of all things which are in the given relation to the word being defined. The structure of the question is also a simple kernel sentence. Through a hierarchical set of functions, the program is capable of taking a kernel-sentence question and, based on its knowledge, providing a one-word answer (true, false, or don't know) accompanied by a copy of the internal semantic structure of the sentence, if any, from which the answer was deduced. The program's capabilities are not infinite, but further details could easily be added. Tables showing the data base, function truth tables, flow charts, and questions and answers are included along with a list of references. (VM)
