Searching handwritten manuscripts

Ian Austen, A New Script for Searching Texts Written by Hand, New York Times, December 30, 2004. Excerpt: '"There is an enormous amount of handwritten stuff locked away in many archives, libraries and museums," said R. Manmatha, a research assistant professor with the Center for Intelligent Information Retrieval at the University of Massachusetts, Amherst. "Most of the time when people do research they just ignore this stuff because it's not accessible."...To develop their system, Dr. Manmatha and his students obtained about 1,000 pages of George Washington's correspondence that had been scanned from microfilm by the Library of Congress....The breakthrough came from looking at research into how people read, Dr. Manmatha said. Rather than analyzing individual letters, he said, people look at words and even parts of sentences as whole units....Even after training, the resulting software lacks the accuracy of programs used to read and digitize printed books, Dr. Manmatha said. But that it is not a significant problem. "That's the difference between having to recognize a thing and having to search it," he said. "You don't have to get every word right." Right now, Dr. Manmatha believes that the system is about 65 percent accurate....Though no library or archive has yet approached Dr. Manmatha about the system, he will brief Google about it early next year. With sufficient funds for software development and document scanning, Dr. Manmatha said, it may be possible within a decade for people to search historical manuscripts from home as easily as they now locate anything else on the Web.'
