5th Tsinghua Interdisciplinary Workshop on Logic, Language and Meaning

The TLLM workshops aim to bring together logicians, philosophers, and linguists around a specific theme of common interest. For the 2026 event, the theme is unusually wide, and we welcome contributions on any general or particular aspect of the modalities in logic or language. Below are just a few examples of possible topics for this workshop. 1 Foundations and semantics of modality: E.g. Kripke/neighborhood/possibility/topological/ game-theoretic/inquisitive/team semantics. 2 Proof theory for modal logic: E.g. sequent/natural deduction/labelled/circular/display/ deep inference systems. 3 Epistemic and doxastic logics. 4 Deontic logic, norms and preference. 5 Modality in natural language: E.g. epistemic/deontic/dynamic modals; weak necessity and gradability; syntax of modals; semantic-pragmatic interface; cross-linguistic typology; experimental and corpus studies. 6 Non-classical perspectives on modality: E.g. intuitionistic/linear/relevant/paraconsistent/ modal bilattice frameworks; bilateralist accounts. 7 Modality in computation, verification, and AI: E.g. KR with modalities; causal and probabilistic modal models; LLMs and modal reasoning (benchmarks, neurosymbolic methods, toolkits). 8 Modality and other intensional categories: e.g. modality and tense; modality and evidentiality; modality and mood. 9 The processing and acquisition of modal expressions in natural languages
