ScienceDaily (Aug. 16, 2012) Inspired by a system for categorising books proposed by an Indian librarian more than 50 years ago, a team of EU-funded researchers have developed a new kind of internet search that takes into account factors such as opinion, bias, context, time and location. The new technology, which could soon be in use commercially, can display trends in public opinion about a topic, company or person over time -- and it can even be used to predict the future.
'Do a search for the word "climate" on Google or another search engine and what you will get back is basically a list of results featuring that word: there's no categorisation, no specific order, no context. Current search engines do not take into account the dimensions of diversity: factors such as when the information was published, if there is a bias toward one opinion or another inherent in the content and structure, who published it and when,' explains Fausto Giunchiglia, a professor of computer science at the University of Trento in Italy.
But can search technology be made to identify and embrace diversity? Can a search engine tell you, for example, how public opinion about climate change has changed over the last decade? Or how hot the weather will be a century from now, by aggregating current and past estimates from different sources?
It seems that it can, thanks to a pioneering combination of modern science and a decades-old classification method, brought together by European researchers in the LivingKnowledge (1) project. Supported by EUR 4.8 million in funding from the European Commission, the LivingKnowledge team, coordinated by Prof. Giunchiglia, adopted a multidisciplinary approach to developing new search technology, drawing on fields as diverse as computer science, social science, semiotics and library science.
