Interactive grammar development with WCDG

چکیده
The manual design of grammars for accurate natural language analysis is an iterative process; while modelling decisions usually determine parser behaviour, evidence from analysing more or different input can suggest unforeseen regularities, which leads to a reformulation of rules, or even to a different model of previously analysed phenomena. We describe an implementation of Weighted Constraint Dependency Grammar that supports the grammar writer by providing display, automatic analysis, and diagnosis of dependency analyses and allows the direct exploration of alternative analyses and their status under the current grammar.

Natural language parsing with graded constraints
Based on the working hypothesis that gradation is a central phenomenon in natural language, this thesis proposes the grammar formalism of weighted constraint dependency grammars (WCDG) as a unified framework for the treatment of gradation. Gradation can be found in different forms in natural language: as a preference for one outcome over another or as an extended notion of grammaticality which ...
متن کاملComparing Rule-Based and Data-Driven Dependency Parsing of Learner Language
We explore the performance of two dependency parsing approaches, the rulebased WCDG approach (Foth and Menzel 2006) and the data-driven dependency parser MaltParser (Nivre et al. 2007) on texts written by language learners. We show that WCDG outperforms MaltParser in identifying the main functorargument relations, whereas MaltParser is more successful than WCDG in establishing optional, adjunct...
متن کاملComic Strips and Grammar Development among Iranian Teenage EFL Learners
This study was an attempt to examine the effect of using comic strips on improving grammar recognition and performance among Iranian young EFL learners. To this end, one experimental and one control groups were formed, each having 45 preintermediate participants chosen via convenience sampling. The researcher-made pretests of grammar and speaking assured the researchers that the participants di...
متن کاملA web-based editor for multiplayer choice games
The structure of a choice-driven interactive story can be modeled as a syntax tree, generated by a player from a grammar, which in turn was generated by a game author. Using this grammar metaphor, “Boswell”, a web-based Integrated Development Environment, was developed for writing, testing, playing and sharing choice-based interactive fiction scripts. The system includes a domain-specific langu...
