个人简介
Over the last fifteen years, Broder pioneered several algorithms systems and concepts fundamental to the science and technology of the WWW. Some of the highlights include: In 1997, Broder led the development of the first practical solution for finding near-duplicate documents on web-scale using "shingling" to reduce the problem to a set-intersection problem and "min-hashing" or to construct "sketches" of sets. This was a pioneering effort in the area of locality-sensitive hashing. In 1998, he co-invented the first practical test to prevent robots from masquerading as human and access web sites, often referred to as CAPTCHA. In 2000, Broder, then at AltaVista, together with colleagues from IBM and DEC SRC, conducted the first large-scale analysis of the Web graph, and identified the bow-tie model of the web graph. Around 2001–2002, Broder published an opinion piece where he qualified the differences between classical information retrieval and Web search and introduced a now widely accepted classification of web queries into navigational, information, and transactional.
