Dates: October 26-28, 2013
Chair:

Co-chair:
  • Daisuke Bekki (Ochanomizu University/National Institute of Informatics)
  • Eric McCready (Aoyama Gakuin University)
Invited Speakers:

Aim and Topics

LENLS is an annual international workshop on formal syntax, semantics and pragmatics. It will be held as one of the workshops of the fifth JSAI International Symposia on AI (isAI2013) sponsored by the Japan Society for Artificial Intelligence (JSAI).

We invite submissions to this year's workshop on topics in formal semantics and pragmatics, and related fields, including but in no way limited to the following:

  • Dynamic syntax/semantics/pragmatics of natural language
  • Categorical/topological/coalgebraic approaches for natural language syntax/semantics/pragmatics
  • Logic and its relation to natural language and linguistic reasoning (especially dynamic logics)
  • Type-theoretic approaches to natural language
  • Formal Philosophy of language
  • Formal pragmatics (especially game-theoretic and utility-theoretic approaches)
  • Substructural expansion of Lambek Lambda Calculi
  • Many-valued/Fuzzy and other non-classical logics and natural language

Selected Papers

We also plan to publish a selection of the accepted/invited papers as a portion of a volume "JSAI-isAI selected papers", which will be published from `Lecture Notes in Artificial Intelligence' series (Springer Verlag).

Important dates:

Abstract submission deadline:August 4, 2013
Notification of acceptance:August 26, 2013
Deadline for camera-ready copy:September 23, 2013
Deadline for onsite registration:October 10, 2013

Title

Vagueness and Fuzzy Logic

Abstract

The aim of this tutorial is to give a positive appraisal of the prospects for a fuzzy logic based solution to the problems of vagueness. The tutorial will be divided into the following sections (time permitting).

I. An overview of the major existing theories of vagueness (epistemicism, additional truth values, truth gaps, supervaluationism, plurivaluationism).

II. The problem of defining vagueness. Shortcomings of previous definitions (e.g. borderline cases, semantic indeterminacy, tolerance). Proposal: vagueness as closeness. If this proposal is correct then the correct theory of vagueness must involve degrees of truth.

III. Fuzzy logic and the problem of artificial precision. Problems with existing solutions (fuzzy epistemicism, fuzzy metalanguage, blurry sets). Proposed solution: fuzzy plurivaluationism -- a theory that combines degrees of truth with semantic indeterminacy of the sort found in 'supervaluationist' (more correctly: plurivaluationist) approaches.

IV. Fuzzy logic and the problem of truth-functionality. It has been argued that fuzzy logic based theories of vagueness are incompatible with data about the assertability of compound propositions in the presence of borderline cases. A negative assessment of these arguments will be given.

V. Integrating the fuzzy theory of vagueness into the wider theoretical landscape. Case study: degrees of belief. In particular, the relationship between degrees of belief arising from uncertainty (ignorance) and degrees of belief arising from vagueness.
