This paper describes a method for definition question answering based on the use of surface text patterns. The method is specially suited to answer questions about person's po...
Abstract-- We introduce a distributed estimation algorithm for use by a collection of stochastically interacting agents. Each agent has both a discrete value and an estimate of the...
One of the main challenges in integrating two hierarchies is determining the correspondence between the edges of each hierarchy. Traditionally, this process, which we call hierarch...
Given a set P of n points in the plane, a Manhattan network of P is a network that contains a rectilinear shortest path between every pair of points of P. A minimum Manhattan netw...
Unsupervised learning algorithms have been derived for several statistical models of English grammar, but their computational complexity makes applying them to large data sets int...
