LTC'07 is scheduled for October 5-7, 2007, at the Faculty of Mathematics and Computer Science of the Adam Mickiewicz University, Poznan, Poland. At the beginning of the 7th Framework Program, recently launched by the European Commission, Human Language Technologies continue to be a challenge for computer science, linguistics and related fields as these technologies become an ever more essential element of our everyday technological environment. Since Ajdukiewicz, Tarski, Turing and Chomsky (i.e. since the very beginning of the Computer Age) these fields have influenced and stimulated each other. Technological, social and cultural globalization has created a favorable climate for the intensive exchange of novel ideas, concepts and solutions across initially distant disciplines. We aim further contribute to this exchange and we invite you to join us at the LTC'07 in October, 2007.
