No matter the question, search engine users expect the machines to provide answers instantaneously, even without searching through relevant websites.\\
\\While a significant portion of these questions ask for concise and well known facts, more complex questions do exist and they often require dedicated approaches to provide robust and accurate systems.\\
\\This thesis explores linguisticallyoriented approaches for both factoid and nonfactoid question answering and applications to crossgenre tasks. The contributions include new annotation schemes for the question answering oriented corpora, extracting linguistic structures and performing matching, and early exploration of applications to conversation dialog tasks.   Seminar: Algebra Survey on recent results on maximal tori of algebraic groups Philippe Gille, CNRS, Lyon   Seminar: Algebra 576 Fermions Theo JohnsonFreyd, Perimeter Institute   Seminar: Combinatorics Packing nearly optimal Ramsey $R(3,t)$ graphs Lutz Warnke, Georgia Institute of Technology   Colloquium The density of squarefree values taken by a polynomial Manjul Bhargava, Princeton   Seminar: Computer Science You Are Already Living Inside a Computer Ian Bogost, Georgia Tech Venue: Mathematics and Science Center, Room W201 Show abstract Futurists and philosophers have made dramatic predictions about the future of computers. Artificial intelligence might end the need for human work, or it might enslave humanity, or it might facilitate a kind of rapture into machines, where people's consciousnesses could upload and, through simulation, become immortal.\\
\\Realized or not, those future visions offer a stark contrast with the reality of computing today: One where digital machinery is embedded in the ordinary, human world rather than leading away from it. The computational aspects of ordinary things from smartphone apps to internetconnected toasters have become goals unto themselves, rather than just a means to an end. As it spreads from desktops and backoffices to pockets, cameras, cars, and door locks, the affection people have with computers transfers onto other, even more ordinary objects. And the more people love using computers for everything, the more life feels incomplete unless it takes place inside them. Reality might have beaten the futurists to the punch, by turning computing into a way of life.
