The Ninth International Tbilisi Symposium on Language, Logic and Computation will be held on 26 -- 30 September 2011 in Kutaisi, Georgia. The Programme Committee invites submissions for contributions to on all aspects of language, logic and computation. Work of an interdisciplinary nature is particularly welcome. Areas of interest include, but are not limited to:

     * Natural language syntax, semantics, and pragmatics
     * Constructive, modal and algebraic logic
     * Linguistic typology and semantic universals
     * Logics for artificial intelligence
     * Information retrieval, query answer systems
     * Logic, games, and formal pragmatics
     * Language evolution and learnability
     * Computational social choice
     * Historical linguistics, history of logic
     * Algorithmic game theory
     * Formal models of multiagent systems

Authors can submit an anonymous abstract of two pages (800 words) at the EasyChair conference system here:

SPECIAL SESSIONS

**Special session on Frames, chaired by Sebastian Loebner**

The workshop deals with theory and application of frames (in the sense of 
Barsalou: attribute-value structures with functional attributes) in the areas 
of Language (Semantics, Syntax, ...), Logic, Computation, Mathematics, and 
Cognitive psychology. Talks are invited that deal with topics such as

     * formal modeling and semantics of frames
     * dynamic modeling of verbs
     * extension of frame theory to different types of concepts
     * dynamic models of frames
     * computational aspects of frames
     * frames as representations in lexical and compositional semantics, syntax, 
morphology, phonology, etc.

**Special session on Logic, Information, and Agency chaired by Alexandru Baltag 
& Sonja Smets**

We ask for submissions applying formal logical methods in a broad sense 
(including non-classical and modal logics, epistemic game theory, algebraic and 
categorical logic, probabilistic approaches etc) to reasoning about information 
and agency. Topics of interest include:

     * Modal Logics for Agency
     * Reasoning about higher-order knowledge or beliefs in Multi-agent Systems
     * Logics for Information Updates (learning, belief revision, theory change, 
conditioning etc.)
     * Logical approaches to strategies, preferences and rationality in 
Epistemic Game Theory
     * Logics for reasoning about protocols, planning and intentions.

Invited Speakers:

Dietmar Berwanger (LSV Cachan)
Jan van Eijck (CWI Amsterdam)
Valentin Goranko (t.b.c.), (Technical University of Denmark)
Emiliano Lorini (Université Paul Sabatier Toulouse)
Alessandra Palmigiano (University of Amsterdam)
