Logical Semantics, Dialogical Argumentation, and Textual Entailment

TL;DR

This paper presents a new dialogical system for first-order logic that aligns with natural language argumentation and uses it for automated textual entailment, bridging semantics and argumentation.

Contribution

It introduces a novel dialogical framework for classical logic integrated with a syntactic-semantic parser to address textual entailment tasks.

Findings

Proves completeness of the dialogical system for classical validity

Demonstrates application to automated textual entailment

Connects natural language semantics with dialogical logic

Abstract

In this chapter, we introduce a new dialogical system for first order classical logic which is close to natural language argumentation, and we prove its completeness with respect to usual classical validity. We combine our dialogical system with the Grail syntactic and semantic parser developed by the second author in order to address automated textual entailment, that is, we use it for deciding whether or not a sentence is a consequence of a short text. This work-which connects natural language semantics and argumentation with dialogical logic-can be viewed as a step towards an inferentialist view of natural language semantics.
