Finding contradiction text is a fundamental problem in natural language understanding. Previous work on finding contradiction in text incorporate information derived from predicate-argument structures as features in supervised machine learning frameworks. In contrast to previous work, we combine shallow semantic representations derived from semantic role labeling with binary relations extracted...

This paper focuses on Aristotle’s discussion of PNC in Metaphysics Gamma and argues that the argument operates at three different levels: ontological, doxastic, semantic through invocation philosophical personae: first one (the philosopher) can only state what is otherwise unprovable, second (a geometer) confirm we should trust PNC, third sophistical opponent) denies must be silenced. Aristotle...

Fuzzy model-based adaptive control, unlike traditional fuzzy control, extracts expert knowledge from data by using model identification techniques. In this paper, we propose an analysis of the contradiction in this knowledge as an additional search criterion during the model identification process. In order to do so, we first define a measure of contradiction between fuzzy rules. Then, we assum...

Appendix B of The Principles of Mathematics (1903) contains Russell’s first statement of his theory of logical types. This simple version of the theory is designed to block the reasoning that leads to the paradox of the Russell class. But Russell notes immediately that new problems arise. The problems culminate in the paradox of propositions. This is a problem that seems to run in exact paralle...

The concept of ‘sustainability’ has become the current answer to absolving the world of its environmental and economic crises in the 21 century. Since its conceptualisation, there has been a barrage of investigations and literature on the vagueness and ambiguity of its definition and applicability. There are two main opposing schools of thought the pessimists, usually ecologists and other scien...
