Converting tree tuple multicomponent tree adjoining grammars (TT-MCTAGs) into range concatenation grammars (RCGs)

چکیده
RÉSUMÉ. Cet article étudie la relation entre le formalisme TT-MCTAG et le formalisme RCG. RCG est connu pour décrire exactement la classe PTIME. TT-MCTAG a été proposé pour modéliser les langues à ordre des mots libre. Nous montrons comment une forme restreinte de TT-MCTAG peut être convertie en une RCG « simple » équivalente. Le résultat est intéressant pour des raisons théoriques (il montre que la forme restreinte est légèrement sensible au contexte), mais également pour des raisons pratiques (la conversion proposée a été implantée dans un analyseur TT-MCTAG).

On the Relation between Multicomponent Tree Adjoining Grammars with Tree Tuples (TT-MCTAG) and Range Concatenation Grammars (RCG)
This paper investigates the relation between TT-MCTAG, a formalism used in computational linguistics, and RCG. RCGs are known to describe exactly the class PTIME; simple RCG even have been shown to be equivalent to linear context-free rewriting systems, i.e., to be mildly context-sensitive. TT-MCTAG has been proposed to model free word order languages. In general, it is NP-complete. In this pap...
متن کاملTree-Local Multicomponent Tree-Adjoining Grammars with Shared Nodes
This article addresses the problem that the expressive power of tree-adjoining grammars (TAGs) is too limited to deal with certain syntactic phenomena, in particular, with scrambling in freeword-order languages. The TAG variants proposed so far in order to account for scrambling are not entirely satisfying. Therefore, the article introduces an alternative extension of TAG that is based on the n...
متن کاملDeveloping a TT-MCTAG for German with an RCG-based Parser
Developing linguistic resources, in particular grammars, is known to be a complex task in itself, because of (amongst others) redundancy and consistency issues. Furthermore some languages can reveal themselves hard to describe because of specific characteristics, e.g. the free word order in German. In this context, we present (i) a framework allowing to describe tree-based grammars, and (ii) an...
متن کاملTuLiPA - Parsing Extensions of TAG with Range Concatenation Grammars
In this paper we present a parsing framework for extensions of Tree Adjoining Grammars (TAG) called TuLiPA (Tübingen Linguistic Parsing Architecture). In particular, besides TAG, the parser can process Tree-Tuple MCTAG with shared nodes (TT-MCTAG), a TAG-extension that has been proposed to deal with scrambling in free word order languages such as German. The central strategy of the parser is su...
متن کاملMulti-Component Tree Insertion Grammars
In this paper we introduce a new mildly context sensitive formalism called Multi-Component Tree Insertion Grammar. This formalism is a generalization of Tree Insertion Grammars in the same sense that Multi-Component Tree Adjoining Grammars is a generalization of Tree Adjoining Grammars. We show that this class of grammatical formalisms is equivalent to Multi-Component Tree Adjoining Grammars, a...
