CALL FOR PAPERS: Workshop on Compositional Meaning in Logic, April 3-7, 2013, Rio de Janeiro, BRAZIL

Affiliated with the 4th World Congress on Universal Logic [UNILOG 2013]

The Fregean-inspired Principle of Compositionality of Meaning (PoC), for formal languages, may be 
construed as asserting that the meaning of a compound expression is deterministically (and often 
recursively) analysable in terms of the meaning of its constituents, taking into account the mode 
in which these constituents are combined so as to form the compound expression.  From a logical 
point of view, this amounts to prescribing a constraint ?that may or may not be respected?
on the internal mechanisms that build and give meaning to a given formal system.  Within the domain
of formal semantics and of the structure of logical derivations, PoC is often directly reflected 
by metaproperties such as truth-functionality and analyticity, characteristic of computationally 
well-behaved logical systems.

The workshop on *Compositional Meaning in Logic* (GeTFun 1.0) is dedicated to the study of various 
well-motivated ways in which such attractive properties and metaproperties may be stretched so as 
to cover more extensive logical grounds.  The ubiquity of non-classical logics in the formalization
of practical reasoning demands the formulation of more flexible theories of meaning and 
compositionality that allow for the establishment of coherent and inclusive bases for their 
understanding.  Such investigations presuppose not only the development of adequate frameworks 
from the perspectives of Model Theory, Proof Theory and Universal Logic, but also the construction 
of solid bridges between the related approaches based on various generalizations of 
truth-functionality.  Applications of broadly truth-functional logics, in their various guises, 
are envisaged in several areas of computer science, mathematics, philosophy and linguistics, where 
the ever increasing complexity of systems continuously raise new and difficult challenges to 

We welcome submissions on all topics related to compositionality of meaning in logic, and in 
particular to issues connected to generalizations of metalogical notions such as:

- truth-functionality
- nondeterminism in semantics
- logical bivalence vs algebraic many-valuedness
- analyticity
- subformula principle and complexity measures
- semantic effectiveness and decision procedures for non-classical logics
- cut-free vs cut-based proof formalisms
- proof strategies and proof-search
- modular logical specification formalisms
- rule invertibility, structurality and logical harmony

Submissions should consist of an abstract of up to 1,000 words, sent by email before 1st Dec 2012 
to .
