We propose a constructive discursive logic with strong negation CDLSN based on Nelson’s constructive logic N as a constructive version of Jaśkowski’s discursive logic. In CDLSN, discursive negation is defined similar to intuitionistic negation and discursive implication is defined as material implication using discursive negation. We give an axiomatic system and Kripke semantics with a complete...

In this thesis I have addressed the problem of text summarization from a linguistic perspective. After reviewing some work in the area, I have found that many satisfactory approaches to text summarization rely on general properties of language that are reflected in the surface realization of texts. The main claim of this thesis is that some general properties of the discursive organization of t...

In the logical literature, Discursive (or Discussive) Logic introduced by Stanis law Jaśkowski is seen as one of the earliest examples of the so-called paraconsistent logic. There is some confusion over what is actually discursive logic nevertheless.

This paper describes how discursive knowledge, given by the discursive theories RST (Rhetorical Structure Theory) and CST (Crossdocument Structure Theory), may improve the automatic evaluation of local coherence in multi-document summaries. Two of the main coherence models from literature were incremented with discursive information and obtained 91.3% of accuracy, with a gain of 53% in relation...

The Anthropocene is giving rise to novel challenges for global environmental governance. barriers and opportunities shaping the ways in which some of these complex become governable on level are increasing academic practical relevance. In this article, we bring neo-institutionalist post-structuralist perspectives together an innovative framework analyse how both institutional discursive structu...

This article argues that a discursive–sociological approach to study Europeanization is particularly apt for understanding the dynamics of policy change in Europe. It does so by bringing closer the agenda of discursive institutionalism (DI) and gender policy analysis, drawing upon the recent sociological and discursive turns in the study of the domestic impact of Europe, and the long-term inter...
