PAC Learning Constraint Dependency Grammar Constraints

چکیده
Constraint Dependency Grammar (CDG) 11, 13] is a constraint-based grammatical formalism that has proven eeective for processing English 5] and improving the accuracy of spoken language understanding systems 4]. However, prospective users of CDG face a steep learning curve when trying to master this powerful formalism. Therefore, a recent trend in CDG research has been to try to ease the burden of grammar writers by developing methods for automatically learning CDG grammars from annotated sentences 22, 23]. In this paper, we prove that CDG grammar constraints are PAC learnable.

Modeling Dependency Grammar with Restricted Constraints
In this paper, parsing with dependency grammar is modeled as a constraint satisfaction problem. A restricted kind of constraints is proposed, which is simple enough to be implemented efficiently, but which is also rich enough to express a wide variety of grammatical well-formedness conditions. We give a number of examples to demonstrate how different kinds of linguistic knowledge can be encoded...
متن کاملApproaches for Learning Constraint Dependency Grammar from Corpora
This paper evaluates two methods of learning constraint dependency grammars from corpora: one uses the sentences directly and the other uses subgrammar expanded sentences. Learning curves and test set parsing results show that grammars generated directly from sentences have a low degree of parse ambiguity but at a cost of a slow learning rate and less grammar generality. Augmenting these senten...
متن کاملWriting Weighted Constraints for Large Dependency Grammars
Implementing dependency grammar as a set of defeasible declarative rules has fundamental advantages such as expressiveness, automatic disambiguation, and robustness. Although an implementation and a successful large-scale grammar of German are available, so far the construction of constraint dependency grammars has not been described at length. We report on techniques that were used to write th...
