Robots learn language


"(PhysOrg.com) -- Communication is a vital part of any task that has to be done by more than one individual. That is why humans in every corner of the world have created their own complex languages that help us share the goal. As it turns out, we are not alone in that need, or in our ability to create a language of our own.
Researchers at the University of Queensland and Queensland University of Technology have created a pair of robots who are creating their own language. The bots, which are being taught how to speak but not given specific languages, are learning to create a lexicon of their own.
The bots, which have been aptly named Lingodroids, consist of a fairly basic setup when it comes to hardware. The robot consists of a  that has been equipped with a camera, a laser range finder, and a sonar setup that allows for the mapping and avoidance of obstacle. In order to allow them to talk, they are also equipped with a  and speakers.
The Lingodroids develop language in the way that most human languages have probably developed, but making up words to name the places that they visit, and then share that name with the other around you. The bots basically find something that they have not seen in the past, create a word based on a random combination of , and then tell the other  the word that they have just created. Then the robots memory files will link to the word to that specific location.
Currently the robots are learning new words by , and can only name locations, but the researchers hope that in the future these Lingodroids will be able to create a more complex language.

How to Talk with a Dolphin

"A DIVER carrying a computer that tries to recognise dolphin sounds and generate responses in real time will soon attempt to communicate with wild dolphins off the coast of Florida. If the bid is successful, it will be a big step towards two-way communication between humans and dolphins."

A Universal Philosophical Refutation

A philosopher once had the following dream:
First, Aristotle appeared, and the philosopher said to him, "Could you give me a fifteen-minute capsule sketch of your entire philosophy?" To the philosopher's surprise, Aristotle gave him an excellent exposition in which he compressed an enormous amount of material into a mere fifteen minutes. But then the philosopher raised a certain objection which Aristotle couldn't answer. Confounded, Aristotle disappeared.
Then Plato appeared. The same thing happened again, and the philosophers' objection to Plato was the same as his objection to Aristotle. Plato also couldn't answer it and disappeared.
Then all the famous philosophers of history appeared one-by-one and our philosopher refuted every one with the same objection.
After the last philosopher vanished, our philosopher said to himself, "I know I'm asleep and dreaming all this. Yet I've found a universal refutation for all philosophical systems! Tomorrow when I wake up, I will probably have forgotten it, and the world will really miss something!" With an iron effort, the philosopher forced himself to wake up, rush over to his desk, and write down his universal refutation. Then he jumped back into bed with a sigh of relief.
The next morning when he awoke, he went over to the desk to see what he had written.

It was, "That's what you say."

"New Words" by George Orwell

From an unpublished essay by G. Orwell, written around 1940:
"At present the formation of new words is a slow process (I have read somewhere that English gains about six and loses about four words a year) and no new words are deliberately coined except as names for material objects. Abstract words are never coined at all, though old words (e.g. “condition”, “reflex”, etc.) are sometimes twisted into new meanings for scientific purposes. What I am going to suggest here is that it would be quite feasible to invent a vocabulary, perhaps amounting to several thousands of words, which would deal with parts of our experience now practically unamenable to language. There are several objections to the idea, and I will deal with these as they arise. The first step is to indicate the kind of purpose for which new words are needed."
