R2 - A Natural Language Question-Answering System,
Abstract
An intelligent natural language question-answering system called the R2 system is described which exhibits a number of advanced features not found in other question-answering systems. This system is based upon a new high-order logical calculus that permits the representation of a wide range of natural language information. A number of examples are given showing how natural language information is represented in this high-order language. An example illustrating the question-answering ability of the system is also given in which a question is transformed into the high-order representation and the deductive steps necessary for generating the answer are performed.
