Post-plus languages

Post-plus languages

In this paper, a post-plus language is de.ned as a language which contains all the catenations of each word in the language with a proper su0x of this word. The set of all d-primitive words is a natural post-plus language. The family of all post-plus languages is a subfamily of all non-counting languages. Some basic properties and characterizations of post-plus languages are investigated. We ob...

OCR Post-Processing for Low Density Languages

We present a lexicon-free post-processing method for optical character recognition (OCR), implemented using weighted finite state machines. We evaluate the technique in a number of scenarios relevant for natural language processing, including creation of new OCR capabilities for low density languages, improvement of OCR performance for a native commercial system, acquisition of knowledge from a...

Regular languages of plus - and minus - ( in ) decomposable permutations

In this paper we show that the sets of plusrespectively minus-decomposable permutations of a regular class under the rank encoding form regular sublanguages. Plusrespectively minus-decomposable permutations are permutations allowing for a special kind of block-decomposition. The language theoretic results shown have di erent approaches, even though the properties of plusand minus-decomposabilit...

Intervention ventriculography. Comparative value of nitroglycerin, post-extrasystolic potentiation and nitroglycerin plus post-extrasystolic potentiation.

The comparative value of nitroglycerin (TNG), post-extrasystolic potentiation (PESP) and their combination (TNG + PESP) to unmask asynergic residual contraction was examined, each patient serving as his own control. Twelve of 13 hypokinetic zones improved both with TNG and PESP. One remained unchanged with either. Of 15 akinetic zones, four improved with both TNG and PESP, while ten remained un...
