Nicht überraschend bin ich bei meiner Literaturrecherche heute früh auf zwei Aufsätze gestoßen, die mich daran erinnert haben, dass es nichts gibt, was nicht gibt.
Spelling Error Trends in Urdu (Entwicklungsrichtung von Rechtschreibfehlern in Urdu)
Today the most accurate error correction techniques are statistical. But for low resourced languages like Urdu, where training error corpora are not available, statistical techniques are out of the question. Rule based techniques that exploit spelling error trends provide a useful alternative. The study of error patterns in a language is an essential prerequisite for designing such techniques. This paper presents two studies of spelling error trends in Urdu. The results show that alongside the already known spelling error trends common to all languages, Urdu also exhibits some language specific error patterns. The most important among them are space related errors and shape similarity based errors. They form a dominating portion of the total spelling mistakes in Urdu.
Visual methods for the retrieval of guitarist fingering (Visuelle Methode zur Gewinnung von Guitarrengriffen)
This article presents a method to visually detect and recognize fingering gestures of the left hand of a guitarist. This method has been developed following preliminary manual and automated analysis of video recordings. These first analyses led to some important findings about the design methodology of a vision system for guitarist fingering, namely the focus on the effective gesture, the consideration of the action of each individual finger, and a recognition system not relying on comparison against a knowledge base of previously learned fingering positions. Motivated by these results, studies on three aspects of a complete fingering system were conducted: the first on finger tracking; the second on strings and frets detection; and the last one on movement segmentation. Finally, these concepts were integrated into a prototype and a system for left hand fingering detection was developed.
