Winograd Schema Challenge: A Step beyond the Turing Test

The well-known Turing test was first proposed by Alan Turing (1950) as a practical way to defuse what seemed to him to be a pointless argument about whether or not machines could think. He put forward that, instead of formulating such a vague question, we should ask whether a machine would be capable of producing behavior that we would say required thought in people. The sort of behavior he had in mind was participating in a natural conversation in English over a teletype in what he called the Imitation Game. The idea, roughly, was the following: if an interrogator was unable to tell after a long, free flowing and unrestricted conversation with a machine whether s/he was dealing with a person or a machine, then we should be prepared to say that the machine was thinking. The Turing test does have some troubling aspects though.

Once upon a Time in 1954…

Die Grenzen meiner Sprache bedeuten die Grenzen meiner Welt

(The limits of my language are the limits of my world)

Ludwig Wittgenstein, Tractatus Logico-Philosophicus

… In a cold day of January it took place in Washington DC the Georgetown-IBM experiment, the first and most influential demonstration of automatic translation performed throughout the history. Developed jointly by the University of Georgetown and IBM, the experiment implied the automatic translation of more than 60 sentences from Russian into English. The sentences were chosen precisely; there was no syntactic analysis, which could manage to identify the sentence structure. The approach was mainly lexicographic, based on dictionaries in which a certain word had a link to some particular rules.

That episode was a success. Story has it that the level of euphoria amongst the researchers was such that it was stated that within three or five years the problem of the automatic translation would be solved… That was more than 60 years ago and the language problem –the comprehension and generation of messages by the machine- is still pending. Probably this is the last frontier which separates the human intelligence from the artificial intelligence.

Die Grenzen meiner Sprache bedeuten die Grenzen meiner Welt

(Los límites de mi lenguaje son los límites de mi mundo)

Ludwig Wittgenstein, Tractatus logico-philosophicus

… En un frío día de enero tenía lugar en Washington D.C. el experimento Georgetown-IBM, la primera y más influyente demostración de traducción automatizada de la historia. Desarrollado conjuntamente por la Universidad de Georgetown e IBM, el experimento implicaba la traducción automatizada de más de 60 oraciones del ruso al inglés. Las oraciones se escogieron de manera precisa; no había ningún análisis sintáctico que pudiera llegar a detectar la estructura de la oración. El enfoque fue eminentemente lexicográfico, basado en diccionarios en los que una palabra determinada tenía una conexión con unas reglas específicas.

Aquello fue un éxito y, cuenta la historia que, tal fue la euforia entre los investigadores, que se llegó a afirmar que en un plazo de entre tres y cinco años el problema de la traducción automatizada quedaría resuelto… Eso fue hace algo más de 60 años y el problema del lenguaje, de la comprensión y generación de mensajes por parte de una máquina, aún está sin resolver. Probablemente es la última barrera que separa a la inteligencia humana de la inteligencia artificial.
