Scope and mission: the LORI workshop series aims at bringing together researchers working on a wide variety of logic-related fields concerned with the understanding of rationality and interaction. These include Game Theory and Decision Theory, Philosophy and Epistemology, Linguistics, Computer Science and Artificial Intelligence. The series aims at fostering a view of Logic as an interdisciplinary endeavor, and supports the creation of a Chinese community of interdisciplinary researchers. We invite submissions of contributed papers bearing on any of the broad themes of the LORI workshop series.
