Abstract:
Much of interpersonal communication is linguistic, and people exchange linguistic information primarily through speech and through graphical symbolic representation of speech utterances, i.e., writing, printing, typing, etc. In the modern digital age we can represent written communication as sequences of bits grouped into Unicode points, a means which is capable of representing many if not most of the world's extant languages. But much of the world's recorded information is still in visual rather than digital Unicode form; it is in books, newspapers, manuscripts, and letters; on post-its, whiteboards, street signs, or video captions. It may also be in the form of a gesture on a touch pad or mobile phone screen, to allow an alternative method of text entry than a keyboard. The conversion of all of these representations to Unicode for use in the digital world is generally known as Optical Character Recognition (OCR). How might an OCR system be designed to handle all of the world's languages? I'll explain some challenges that make this nontrivial and describe an approach we're exploring at Google.
