Sketches are commonly used in the early stages of design. Our previous system allows users to sketch mechanical systems that the computer interprets. However, some parts of the mechanical system might be too hard or too complicated to express in…

The goal of the work reported here is to capture the commonsense knowledge of non-expert human contributors. Achieving this goal will enable more intelligent human-computer interfaces and pave the way for computers to reason about our world. In the domain…

En este trabajo se ha desarrollado un sistema para la resolución computacional de la anáfora generada en el uso del lenguaje natural por pronombres (personales y demostrativos) y anáforas adjetivas en los diálogos. El método propuesto se basa en el…

En este artículo se presenta un sistema de aprendizaje supervisado para la desambiguación del sentido de las palabras. Dicho sistema se basa en los modelos de probabilidad condicional de máxima entropía. El conocimiento lingüístico se adquiere a partir de un…

The program described here takes as its input a collection of lines, vertices and surfaces describing a scene, and analyzes the scene into a composition of three-dimensional objects. The program does not need to know the form (model, or pattern)…

Knowledge-intensive processes are widely used to recover from errors, handle exceptional cases and complaints, and to improve or adapt a process itself. In this context, evolved Business-Process Reengineering (BPR) techniques are changing to give some answers to this reality. In…

This thesis explores how doctors and nurses use documents to share their knowledge within and across healthcare settings. In addressing this question I draw on a 15-month, multi-sited ethnographic study in several pediatric health care settings, following patients from primary…

This is a reprint of page proofs of Chapter 12 of Perceptrons, M. Minsky and S. Papert, MIT Press 1968, (we hope). It replaces A.I. Memo No. 156 dated March 1968. The perceptron and convergence theorems of Chapter 11 are…

This memo describes PROGRAMMER, a parser for natural language. It consists of a language for writing grammars in the form of programs, and an interpreter which can use these grammars to parse sentence. PROGRAMMER is one part of an integrated…

This paper presents a knowledge-based approach to facilitate the engineering design
process relating to spacecrafts. Because the design evolves over a long time and typically
involves individuals working at different locations and frequently for different
organizations, the degree of collaboration…
