Using Textual Patterns to Learn Expected Event Frequencies
Jonathan A.R. Gordon, Lenhart K. Schubert · UR Research (University of Rochester) · 2012
Commonsense reasoning requires knowledge about the frequency with which ordinary events and activities occur: How often do people eat a sandwich, go to sleep, write a book, or get married? This paper introduces work to ac-quire a knowledge base pairing factoids about such events with frequency categories learned from simple textual patterns. We are releas-ing a collection of the resulting event frequen-cies, which are evaluated for accuracy, and we demonstrate an initial application of the results to the problem of knowledge refinement. 1
