Abstract We present a novel approach to learning taxonomies or concept hierarchies from text. The approach is based on Formal Concept Analysis, a method mainly used for the analysis of data, i.e. for investigating and processing explicitly given information. Our approach is based on the distributional hypothesis, i.e. that nouns or terms are similar to the extent to which they share contexts. F...

The failure of the classical theories for swollen polymer networks was clearly demonstrated by recent differential swelling experiments of Gee, Eichinger and McKenna. We introduce a weaker form of the additivity assumption based on the separation of the gel into "solid"-like and "liquid"-like components. Using simple scaling arguments and the

Accepting a time-symmetric quantum dynamical world with ontological wave functions or fields, we follow arguments that naturally lead to two-boundary interpretation of mechanics. The usual two boundary picture is valid superdeterministic interpretation. It has, however, one unsatisfactory feature. random selection chosen measurement path the universe far too complicated. To avoid it, propose an...

A general framework for priority arguments in classical recursion theory, using iterated trees of strategies, is introduced and used to present new proofs of four fundamental theorems of recursion theory.

A concept of tip vortex cavitation on propellers is described qualitatively, leading to the distinction of trailing vortices, local tip vortices and leading edge vortices. Improvements of the inception behaviour using this distinction are presented. Observations on developed tip vortex cavitation are given to show that the concept of vortex bursting seems inadequate. The problem of "broadband" ...

I consider paradoxical spectrum arguments involving transitive relations like ‘better than’. argue that, despite being formally different from sorites arguments, at least some arise vagueness, and that vagueness might often be the most natural diagnosis.
