A Constraint Driven Metagrammar
نویسندگان
چکیده
We present an operational framework allowing to express a large scale Tree Adjoining Grammar (TAG) by using higher level operational constraints on tree descriptions. These constraints first meant to guarantee the well formedness of the grammatical units may also be viewed as a way to put model theoretic syntax at work through an efficient offline grammatical compilation process. Our strategy preserves TAG formal properties, hence ensures a reasonable processing efficiency.

Argument linking in LTAG: A constraint-based implementation with XMG
This paper develops a first systematic approach to argument linking in LTAG, building on typologically oriented work in Van Valin (2005). While Van Valin's argument linking mechanism is procedurally defined, we propose a constraint-based implementation. The advantage is that we can separate between the linguistic generalizations to be captured and algorith-mic considerations. The implementation...
متن کاملThe Metagrammar Compiler: An NLP Application with a Multi-paradigm Architecture
The concept of metagrammar has been introduced to factorize information contained in a grammar. A metagrammar compiler can then be used to compute an actual grammar from a metagrammar. In this paper, we present a new metagrammar compiler based on 2 important concepts from logic programming, namely (1) the Warren’s Abstract Machine and (2) constraints on finite set.
متن کاملGenerating LFGs with a MetaGrammar
In this paper, we build up on the work presented in [Clément and Kinyon, 2003b], and [Kinyon and Rambow, 2003b]: we present the notion of MetaGrammar, which was originally successfully used to ease the development and maintenance of large Tree-Adjoining Grammars. We explain how we reuse the notion of MetaGrammar in order to generate LFGs. The main idea is that a compact MetaGrammar hierarchy is...
متن کاملMetagrammar engineering: Towards systematic exploration of implemented grammars
When designing grammars of natural language, typically, more than one formal analysis can account for a given phenomenon. Moreover, because analyses interact, the choices made by the engineer influence the possibilities available in further grammar development. The order in which phenomena are treated may therefore have a major impact on the resulting grammar. This paper proposes to tackle this...
متن کاملA Metagrammar for Vietnamese LTAG
We present in this paper an initial investigation into the use of a metagrammar for explicitly sharing abstract grammatical specifications for the Vietnamese language. We first introduce the essential syntactic mechanisms of the Vietnamese language. We then show that the basic subcategorization frames of Vietnamese can be compactly represented by classes using the XMG formalism (eXtensible Meta...
