چکیده

We present a dependency-driven parser that parses both dependency structures and constituent structures. Constituency representations are automatically transformed into dependency representations with complex arc labels, which makes it possible to recover the constituent structure with both constituent labels and grammatical functions. We report a labeled attachment score close to 90% for dependency versions of the TIGER and TüBaD/Z treebanks. Moreover, the parser is able to recover both constituent labels and grammatical functions with an F-Score over 75% for TüBa-D/Z and over 65% for TIGER.

Feature Engineering in Persian Dependency Parser

Dependency parser is one of the most important fundamental tools in the natural language processing, which extracts structure of sentences and determines the relations between words based on the dependency grammar. The dependency parser is proper for free order languages, such as Persian. In this paper, data-driven dependency parser has been developed with the help of phrase-structure parser fo...

Graph Transformations in Data-Driven Dependency Parsing

Transforming syntactic representations in order to improve parsing accuracy has been exploited successfully in statistical parsing systems using constituency-based representations. In this paper, we show that similar transformations can give substantial improvements also in data-driven dependency parsing. Experiments on the Prague Dependency Treebank show that systematic transformations of coor...

A Hybrid Constituency-Dependency Parser for Swedish

We present a data-driven parser that derives both constituent structures and dependency structures, alone or in combination, in one and the same process. When trained and tested on data from the Swedish treebank Talbanken05, the parser achieves a labeled dependency accuracy of 82% and a labeled bracketing F-score of 75%.

Downstream use of syntactic analysis: does representation matter?

Research in syntactic parsing is largely driven by progress in intrinsic evaluation and there have been impressive developments in recent years in terms of evaluation measures, such as F-score or labeled accuracy. At the same time, a range of different syntactic representations have been put to use in treebank annotation projects and there have been studies measuring various aspects of the ”lea...
