In order to realize the full potential of dependency-based syntactic parsing, it is desirable to allow non-projective dependency structures. We show how a datadriven deterministic dependency parser, in itself restricted to projective structures, can be combined with graph transformation techniques to produce non-projective structures. Experiments using data from the Prague Dependency Treebank s...

We introduce a new dependency treebank for Croatian within the Universal Dependencies framework. We construct it on top of the SETIMES.HR corpus, augmenting the resource by additional part-of-speech and dependency-syntactic annotation layers adherent to the framework guidelines. In this contribution, we outline the treebank design choices, and we use the resource to benchmark dependency parsing...

Pure statistical parsing systems achieves high in-domain accuracy but performs poorly out-domain. In this paper, we propose two different approaches to produce syntactic dependency structures using a large-scale hand-crafted HPSG grammar. The dependency backbone of an HPSG analysis is used to provide general linguistic insights which, when combined with state-of-the-art statistical dependency p...

Tesnière (1959) is often regarded as the founder of the modern theoretical tradition of dependency grammar, but it is not one well-defined theory. Instead, it comprises several related theories, having some core notions in common. Such a notion is the directed relations between pairs of lexical elements, but the formalism and the criteria for this can vary. The primary goal of this study is to ...

Parsing human-human conversations consists in automatically enriching text transcription with semantic structure information. We use in this paper a FrameNet-based approach to semantics that, without needing a full semantic parse of a message, goes further than a simple flat translation of a message into basic concepts. FrameNet-based semantic parsing may follow a syntactic parsing step, howeve...

Syntactic parsing in NLP is the task of working out the grammatical structure of sentences. Some of the purely formal approaches to parsing such as phrase structure grammar, dependency grammar have been successfully employed for a variety of languages. While phrase structure based constituent analysis is possible for fixed order languages such as English, dependency analysis between the grammat...

Space-delimited words in Turkish and Hebrew text can be further segmented into meaningful units, but syntactic and semantic context is necessary to predict segmentation. At the same time, predicting correct syntactic structures relies on correct segmentation. We present a graph-based lattice dependency parser that operates on morphological lattices to represent different segmentations and morph...

We present a novel scheme for wordbased Japanese typed dependency parser which integrates syntactic structure analysis and grammatical function analysis such as predicate-argument structure analysis. Compared to bunsetsu-based dependency parsing, which is predominantly used in Japanese NLP, it provides a natural way of extracting syntactic constituents, which is useful for downstream applicatio...
