Workshop on Compositional Meaning in Logic [GeTFun 4.0]
  Affiliated with
  8th International Joint Conference on Automated Reasoning
Coimbra, Portugal
July 1-2, 2016
Submission deadline: April 15, 2016

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.

After the success of its first, second and third editions, the
workshop GeTFun 4.0 is dedicated to the study of various
well-motivated ways in which the attractive properties and
metaproperties of truth-functional logics 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 compositionality.

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, consisting of an abstract of up to 1,000 words, should be
sent by email before April 15, 2016 to the Gmail account: getfunw.

At least one author of each accepted contribution is expected to
participate in the workshop and present the work. Each contributed
talk is planned to have the duration of 25 minutes, divided into 20
minutes of presentation and 5 minutes of discussion.

The charge for participation is 50€/day, a fee covering the welcome
kit, coffee breaks and lunch.
