Parsing German

چکیده
The first part of this paper is dedicated to an overview of the parser of the system VIE-LANG (Viennese Language Understanding System). The parser is a production system which uses an interleaved method that combines syntax and semantics. It parses directly into the internal representation of the system, without producing an intermediate syntactic structure. The last part discusses the relationship between some special features of the German language, and properties of the parser that originate in the language.

The PaGe 2008 Shared Task on Parsing German
The ACL 2008 Workshop on Parsing German features a shared task on parsing German. The goal of the shared task was to find reasons for the radically different behavior of parsers on the different treebanks and between constituent and dependency representations. In this paper, we describe the task and the data sets. In addition, we provide an overview of the test results and a first analysis.
متن کاملParsing Three German Treebanks: Lexicalized and Unlexicalized Baselines
Previous work on German parsing has provided confusing and conflicting results concerning the difficulty of the task and whether techniques that are useful for English, such as lexicalization, are effective for German. This paper aims to provide some understanding and solid baseline numbers for the task. We examine the performance of three techniques on three treebanks (Negra, Tiger, and TüBa-D...
متن کاملStatistical parsing for German: modeling syntactic properties and annotation differences
Statistical parsing research can be described as being anglo-centric: new models are first proposed for English parsing, and only then tested in other languages. Indeed, a standard approach to parsing with new treebanks is to adapt fully developed English parsing models to the other language. In this dissertation, however, we claim that many assumptions of English parsing do not generalize to o...
متن کاملKnowledge Sources for Constituent Parsing of German, a Morphologically Rich and Less-Configurational Language
We study constituent parsing of German, a morphologically rich and less-configurational language. We use a probabilistic context-free grammar treebank grammar that has been adapted to the morphologically rich properties of German by markovization and special features added to its productions. We evaluate the impact of adding lexical knowledge. Then we examine both monolingual and bilingual appr...
متن کاملIs it Really that Difficult to Parse German?
This paper presents a comparative study of probabilistic treebank parsing of German, using the Negra and TüBa-D/Z treebanks. Experiments with the Stanford parser, which uses a factored PCFG and dependency model, show that, contrary to previous claims for other parsers, lexicalization of PCFG models boosts parsing performance for both treebanks. The experiments also show that there is a big diff...
متن کاملImproving coverage and parsing quality of a large-scale LFG for German
We describe experiments in parsing the German TIGER Treebank. In parsing the complete treebank, 86.44% of the sentences receive full parses; 13.56% receive fragment parses. We discuss the methods used to enhance coverage and parsing quality and we present an evaluation on a gold standard, to our knowledge the first one for a deep grammar of German. Considering the selection performed by our cur...
