LivingKnowledge goal is to bring a new quality into search and knowledge management technology for more concise, complete and contextualised search results.
The system was developed as part of the LivingKnowledge project by the Natural Language Retrieval Group at Yahoo! Research Barcelona; details have been published on Technology Review. The team members include Michael Matthews, Pancho Tolchinsky, Roi Blanco, Jordi Atserias, Peter Mika and Hugo Zaragoza and incorporate many of the ideas first suggested by Ricardo Baeza-Yates in his 2005 paper Searching the Future.
The Time Explorer is an application designed for analyzing how news changes over time that extends upon current time-based systems in many important ways. First, Time Explorer is designed to help users discover how entities such as people and locations associated with a query change over time. Second, by searching on time expressions extracted automatically from text, the application allows the user to explore not only how topics evolved the past, but also how they will continue to evolve in the future. Finally, Time Explorer is designed around an intuitive interface that allows users to interact with time and entities in a powerful way. While aspects of these features can be found in other systems, they are combined in Time Explorer in a way that allows searching through time in no time at all.
A first prototype of Time Explorer was created as part of the HCIR Challenge on Sun, 22 Aug 2010 in New Brunswick, NJ. The challenge participants were asked to create demonstration applications using the NYT Corpus of 1.8 million documents published between 1987 and 2007 that were not only engaging and fun to use, but also allowed users to interact with and learn from documents in new and productive ways. During the demonstration, Time Explorer was used to investigate the history of the conflict in Yugoslavia and to discover a surprising relationship between Saddam Hussein and Slobodan Milosevic that included a sale of arms between Iraq and Yugoslavia The system was also used to examine predictions made in the New York Times about the year 2010 including the correct prediction that there would be a UK election between Gordon Brown and David Cameron that Cameron would likely win and the wildly of the mark suggestion that there might still be a budget surplus in the U.S. Finally the system was used to look at predictions made about the future of Iraq including the possibility that Iraq could develop missiles capable of hitting the U.S. by the year 2015. Of the six systems selected to participate in the challenge, Time Explorer was chosen as the most favored system by the workshop attendees.
