This paper provides an overview of current research on a hybrid and robust parsing architecture for the morphological, syntactic and semantic annotation of German text corpora. The novel contribution of this research lies not in the individual parsing modules, each of which relies on state-of-the-art algorithms and techniques. Rather what is new about the present approach is the combination of these modules into a single architecture. This combination provides a means to significantly optimize the performance of each component, resulting in an increased accuracy of annotation.
In this study, cross-dialectal variation in the use of the acoustic cues of VOT and F0 to mark the laryngeal contrast in Korean stops is examined with Chonnam Korean and Seoul Korean. Prior experimental results (Han & Weitzman, 1970; Hardcastle, 1973; Jun, 1993 &1998; Kim, C., 1965) show that pitch values in the vowel onset following the target stop consonants play a supplementary role to VOT in designating the three contrastive laryngeal categories. F0 contours are determined in part by the intonational system of a language, which raises the question of how the intonational system interacts with phonological contrasts. Intonational difference might be linked to dissimilar patterns in using the complementary acoustic cues of VOT and F0. This hypothesis is tested with 6 Korean speakers, three Seoul Korean and three Chonnam Korean speakers. The results show that Chonnam Korean involves more 3-way VOT and a 2-way distinction in F0 distribution in comparison to Seoul Korean that shows more 3-way F0 distribution and a 2-way VOT distinction. The two acoustic cues are complementary in that one cue is rather faithful in marking 3-way contrast, while the other cue marks the contrast less distinctively. It also seems that these variations are not completely arbitrary, but linked to the phonological characteristics in dialects. Chonnam Korean, in which the initial tonal realization in the accentual phrase is expected to be more salient, tends to minimize the F0 perturbation effect from the preceding consonants by taking more overlaps in F0 distribution. And a 3-way distribution of VOT in Chonnam Korean, as compensation, can be also understood as a durational sensitivity. Without these characteristics, Seoul Korean shows relatively more overlapping distribution in VOT and more 3-way separation in F0 distribution.
Adverbien der Art und Weise im Deutschen und Englischen: zu ihrer Stellung und Interpretation
(2002)
Während es für das Englische seit langem bekannt ist, dass die Interpretation bestimmter ambiger Adverbien von ihrer Stellung abhängt, soll hier gezeigt werden, dass ähnliche Fakten auch im Deutschen zu beobachten sind. Sie können als Hinweis darauf genommen werden, dass bestimmte Adverbialtypen bestimmte Grundpositionen im deutschen Satz haben. Als Beispiel werden in diesem Aufsatz Adverbien der Art und Weise herangezogen, deren Stellungsregularitäten im Englischen und Deutschen auf den ersten Blick völlig unterschiedlich sind. Es wird gezeigt, dass die Stellung dieser Adverbien einer sprachübergreifenden Regularität folgt und dass die zu beobachtenden Unterschiede in der Stellung auf die unterschiedlichen Satzstrukturen des Deutschen und des Englischen zurückzuführen sind.
We present an architecture for the integration of shallow and deep NLP components which is aimed at flexible combination of different language technologies for a range of practical current and future applications. In particular, we describe the integration of a high-level HPSG parsing system with different high-performance shallow components, ranging from named entity recognition to chunk parsing and shallow clause recognition. The NLP components enrich a representation of natural language text with layers of new XML meta-information using a single shared data structure, called the text chart. We describe details of the integration methods, and show how information extraction and language checking applications for realworld German text benefit from a deep grammatical analysis.
This paper follows a new perspective on speech errors within the framework of Articulatory Phonology, as proposed by Goldstein et al. (in prep.). On the basis of kinematic evidence, their work has demonstrated that speech errors are not restricted to categorical exchanges of position of segmental units, but rather gestures that compose segments can exhibit errors that vary from zero to maximal in magnitude.
Here we report results from two perceptual experiments which use stimuli selected on the basis of their articulatory properties only, covering a range of errorful gestural activations. The outcome of the perceptual experiments suggests that different segments show different degrees of vulnerability to (subsegmental) speech errors: While listeners detected errors reliably for some segments, for other segments the reaction to errorful and non-errorful tokens was not distinct. The data suggest that at least for some error types an asymmetric error distribution arises due to perception, while production itself is not asymmetric. However, for error types involving segments whose gestural compositions stand in a subset relationship to each other (as described below), asymmetries may indeed originate in production due to the overall dominance of a gestural intrusion bias observed in the production data of Goldstein et al. (in prep.).
