Answering Comparison Questions in SHAKEN: A Progress Report

Abstract

An important class of questions for knowledge based systems concern comparisons, such as How is X like Y? and How are X and Y different? This paper describes how we have used a cognitive simulation of analogical processing to answer such questions, to support domain experts in entering new knowledge. We outline techniques for case construction and summarization of comparison results that have been developed and refined based on an independent formative evaluation. In addition to these techniques, we discuss the role of the comparison system in SHAKEN, the larger system in which they are embedded, and our plans for further improvements.
