In this article, we present a language-independent, unsupervised approach to sentence boundary detection. It is based on the assumption that a large number of ambiguities in the determination of sentence boundaries can be eliminated once abbreviations have been identified. Instead of relying on orthographic clues, the proposed system is able to detect(More)
Prepositions are highly polysemous. Yet, little effort has been spent to develop language-specific annotation schemata for preposition senses to systematically represent and analyze the polysemy of prepositions in large corpora. In this paper, we present an annotation schema for preposition senses in German. The annotation schema includes a hierarchical(More)
We describe a language-independent, flexible , and accurate method for the detection of abbreviations in text corpora. It is based on the idea that an abbreviation can be viewed as a collocation, and can be identified by using methods for collocation detection such as the log likelihood ratio. Although the log likelihood ratio is known to show a good recall(More)
The realization of singular count nouns without an accompanying determiner inside a PP (determinerless PP, bare PP, Preposition-Noun Combination) has recently attracted some interest in computational linguistics. Yet, the relevant factors for determiner omission remain unclear , and conditions for determiner omission vary from language to language. We(More)
In this paper, we describe a new unsupervised sentence boundary detection system and present a comparative study evaluating its performance against different systems found in the literature that have been used to perform the task of automatic text segmentation into sentences for English and Portuguese documents. The results achieved by this new approach(More)
Language documentation projects supported by recent funding intiatives have created a large number of multimedia corpora of typologically diverse languages. Most of these corpora provide a manual alignment of transcription and audio data at the level of larger units, such as sentences or intonation units. Their usefulness both for corpus-linguistic and(More)
