The paper provides a logical theory of a specific class of natural language expressions
called intermediate quantifiers (most, a lot of, many, a few, a great deal of, a large part of, a …

Since Störring's (1908) pioneering experiments on syllogistic reasoning at the beginning of
the last century, experimental psychology has investigated deductive reasoning in the …

Various semantics for studying the square of opposition and the hexagon of opposition have
been proposed recently. We interpret sentences by imprecise (set-valued) probability …

We present a unified approach for investigating rational reasoning about basic argument
forms involving indicative conditionals, counterfactuals, and basic quantified statements …

We study probabilistically informative (weak) versions of transitivity by using suitable
definitions of defaults and negated defaults in the setting of coherence and imprecise …

In this paper, we continue development of the formal theory of intermediate quantifiers which
are expressions of the natural language (“most”,“many”,“few”, etc.). In the previous paper, we …

In this study, we compared the everyday meanings of conditionals (“if p then q”) and
universally quantified statements (“all p are q”) when applied to sets of elements. The …

Various semantics for studying the square of opposition have been proposed recently. So
far, only [14] studied a probabilistic version of the square where the sentences were …

A coherence-based probability semantics for categorical syllogisms of Figure I, which have
transitive structures, has been proposed recently (Gilio, Pfeifer, & Sanfilippo 15). We extend …
