Both on input and output side additional challenges appear when working on speech rather than text i. On the processing side, different human languages bring a different set of difficulties and techniques developed for one language e. English will need modifications to use for another language e. The growth of NLP is aided by advances in Artificial Intelligence especially Machine Learning and Neural Networks and Computational Linguistics besides the increase in computer processing speeds and storage space. Input recognition The input recognition has 2 main areas i.
The technology to understand the images of typed or printed text is called Optical Character Recognition OCR and is fairly common. It may compare the image to a stored character image on the pixel by pixel basis or on the basis of features. In fact, technology has advanced to an extent that various free online tools are available.
One obvious use is to convert the printed text of books and newspapers to electronic form including a text of yesteryears.
- Machine learning has been used to automatically translate long-lost languages.
- Product details.
- Applied Functional Analysis.
The output is editable as well as searchable. The technology can also find pieces of texts in images e. One area of research is handwriting recognition. Decoding text from handwritten pages uses OCR but needs the additional input of the same handwriting that is used as the target data.
This is used to "train" the underlying Neural network to improve accuracy.
Hasta la vista, robot voice
This feature is available in various versions of Windows, OS, Linux etc. The more common handwriting recognition use case is the online part where a person feeds data into a tablet or a laptop using a stylus or finger. This looks like a natural method to use but accuracy and speed have limited its use to small inputs. Speech recognition is more challenging than text recognition as it has to deal with factors e.
Some research is also happening on use of natural languages as programming languages e. Wolfram Mathematica. In the near future, systems based on deep learning will help diagnose diseases and recommend treatments. Yet despite these impressive advances, one fundamental capability remains elusive: language. If AI is to be truly transformative, this must change. Even though AlphaGo cannot speak, it contains technology that might lead to greater language understanding.
It will help determine whether we have machines we can easily communicate with—machines that become an intimate part of our everyday life—or whether AI systems remain mysterious black boxes, even as they become more autonomous. Perhaps the same techniques that let AlphaGo conquer Go will finally enable computers to master language, or perhaps something else will also be required.
But without language understanding, the impact of AI will be different. Of course, we can still have immensely powerful and intelligent software like AlphaGo. But our relationship with AI may be far less collaborative and perhaps far less friendly.
I wanted to visit the researchers who are making remarkable progress on practical applications of AI and who are now trying to give machines greater understanding of language. With curly white hair and a bushy mustache, he looks the part of a venerable academic, and he has an infectious enthusiasm. Back in , Winograd made one of the earliest efforts to teach a machine to talk intelligently. Incredible strides were being made in AI, and others at MIT were building complex computer vision systems and futuristic robot arms.
Not everyone was convinced that language could be so easily mastered, though. But there was reason to be optimistic, too.

Called ELIZA, it was programmed to act like a cartoon psychotherapist, repeating key parts of a statement or asking questions to encourage further conversation. Weizenbaum was shocked when some subjects began confessing their darkest secrets to his machine. Winograd wanted to create something that really seemed to understand language. He began by reducing the scope of the problem. SHRDLU a nonsense word formed by the second column of keys on a Linotype machine could describe the objects, answer questions about their relationships, and make changes to the block world in response to typed commands.
But it was just an illusion. Just a few years later, he had given up, and eventually he abandoned AI altogether to focus on other areas of research. Winograd concluded that it would be impossible to give machines true language understanding using the tools available then. This is precisely why, before the match between Sedol and AlphaGo, many experts were dubious that machines would master Go. But even as Dreyfus was making that argument, a few researchers were, in fact, developing an approach that would eventually give machines this kind of intelligence. Taking loose inspiration from neuroscience, they were experimenting with artificial neural networks—layers of mathematically simulated neurons that could be trained to fire in response to certain inputs.
To begin with, these systems were painfully slow, and the approach was dismissed as impractical for logic and reasoning. Proponents maintained that neural networks would eventually let machines to do much, much more. One day, they claimed, the technology would even understand language. Over the past few years, neural networks have become vastly more complex and powerful. The approach has benefited from key mathematical refinements and, more important, faster computer hardware and oodles of data.
By , researchers at the University of Toronto had shown that a many-layered deep-learning network could recognize speech with record accuracy. And then in , the same group won a machine-vision contest using a deep-learning algorithm that was astonishingly accurate.

A deep-learning neural network recognizes objects in images using a simple trick. A layer of simulated neurons receives input in the form of an image, and some of those neurons will fire in response to the intensity of individual pixels. Create account. A twitter account will soon be launched! This year, on the theme of "Artificial Intelligence and Cognition". The conference cycle has now a brand new website , although only in French for now.
