A satisfactory proof of the equivalence of wave mechanics and matrix mechanics was only provided later, when von Neumann (1932) showed that both approaches could be seen as different realisations of an abstract Hilbert space formalism.
With the country's solvency hanging by a thread in the wake of the Cypriot parliament's overwhelming rejection of the tough terms attached to financial rescue from the EU and IMF, panic has gradually replaced anger and the shock born of the brutal realisation that bankruptcy is no longer an abstract concept.

Surface realisation can be viewed as the task of mapping abstract sentence representations to word strings in a target language.
We described a 2-stage shallow surface realisation system for Brazilian Portuguese generation that takes as an input an abstract sentence representation and over-generates multiple candidate sentences with the aid of a small set of language-dependent linearisation rules.
As a first initiative towards standardisation in the field, the first Surface Realisation Shared Task [12] intended to evaluate English surface realisation systems based on the same input data (abstracted from the WSJ corpus).
