IT IS WELL KNOWN that Western languages are 50% redundant. Experiment shows that if an average person guesses the successive words in a completely unknown sentence he has to be told only half of them. Experiment shows that this also applies to guessing the successive word-ideas in a foreign language. | Mechanical Translation vol.3 no.2 November 1956 pp. 38-39 Stochastic Methods of Mechanical Translation Gilbert W. King International Telemeter Corp. Los Angeles California IT IS WELL KNOWN that Western languages are 50 redundant. Experiment shows that if an average person guesses the successive words in a completely unknown sentence he has to be told only half of them. Experiment shows that this also applies to guessing the successive word-ideas in a foreign language. How can this fact be used in machine translation It is clear that the success of the human in achieving a probability of .50 in anticipating the words in a sentence is largely due to his experience and the real meanings of the words already discovered. One cannot yet profitably discuss a machine with these capabilities. However a machine translator has a much easier problem - it does not have to make a choice from the wide field of all possible words but is given in fact the word in the foreign language and only has to select One from a few possible meanings. In machine translation the procedure has to be generalized from guessing merely the next word. The machine may start anywhere in the sentence and skip around looking for clues. The procedure for estimating the probabilities and selecting the highest may be classified into several types depending on the type of hardware in the particular machine-translating system to be used. It is appropriate to describe briefly the system currently planned and under construction. The central feature is a high-density store. This ultimately will have a capacity of one billion bits and a random access time of 20 milliseconds. Information from the store is delivered to a high-speed data processor. A text reader supplies the input and a high-speed printer delivers the output. The store serves as a dictionary which is quite different from an ordinary manual type. Basically of course the store contains the foreign words and their equivalents. The capacity is so large
