Abstract

Freer-word-order languages such as German exhibit linguistic phenomena that present unique challenges to traditional CFG parsing. Such phenomena produce discontinuous constituents, which are not naturally modelled by projective phrase structure trees. In this paper, we examine topological field parsing, a shallow form of parsing which identifies the major sections of a sentence in relation to the clausal main verb and the subordinating heads. We report the results of topological field parsing of German using the unlexicalized, latent variable-based Berkeley parser (Petrov et al., 2006) Without any language- or model-dependent adaptation, we achieve state-of-the-art results on the TüBa-D/Z corpus, and a modified NE-GRA corpus that has been automatically annotated with topological fields (Becker and Frank, 2002). We also perform a qualitative error analysis of the parser output, and discuss strategies to further improve the parsing results.

EACL '03: Proceedings of the tenth conference on European chapter of the Association for Computational Linguistics - Volume 1

We present a new grammar formalism for parsing with freer word-order languages, motivated by recent linguistic research in German and the Slavic languages. Unlike CFGs, these grammars contain two primitive notions of constituency that are used to ...
LLLR parsing
SAC '13: Proceedings of the 28th Annual ACM Symposium on Applied Computing

The idea of an LLLR parsing is presented. An LLLR(k) parser can be constructed for any LR(k) grammar but it produces the left parse of the input string in linear time (in respect to the length of the derivation) without backtracking. If used as a basis ...
