From minimal logical forms for answer extraction to logical graphs for question answering

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


Many exciting things happened since I left the ExtrAns project at the University of Zurich. In this paper I present a very brief journal of the research that derived from my work at Zurich. My work combined a study of several representations of questions and answer sentences with the development of procedures to and the answer. The culmination of this work was the definition of the Logical Graphs (LGs), which are graph representations derived from ExtrAns' original Minimal Logical Forms (MLFs), and the development of a method for the automatic learning of question-answer patterns based on LGs. I hope the reader will enjoy reading this journey of ideas.
