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(More)
Although Tree Adjoining Grammars (TAG) are widely used for syntactic processing, there is to date no large scale TAG available which also supports semantic construction. In this paper, we present a highly factorised way of implementing a syntax/semantic interface in TAG. We then show how the resulting resource can be used to perform semantic construction(More)
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(More)
In this article, we introduce eXtensible MetaGrammar (XMG), a framework for specifying tree-based grammars such as Feature-Based Lexicalised Tree-Adjoining Grammars (FB-LTAG) and Interaction Grammars (IG). We argue that XMG displays three features which facilitate both grammar writing and a fast prototyping of tree-based grammars. Firstly, XMG is fully(More)
In this paper, we present an open-source parsing environment (Tübingen Linguistic Parsing Architecture, TuLiPA) which uses Range Concatenation Grammar (RCG) as a pivot formalism, thus opening the way to the parsing of several mildly context-sensitive formalisms. This environment currently supports tree-based grammars (namely Tree-Adjoining Grammars (TAG)(More)
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(More)
Blache [1] introduced Property Grammar as a formalism where linguistic information is represented in terms of non hierarchical constraints. This feature gives it an adequate expressive power to handle complex linguistic phenomena, such as long distance dependencies, and also agrammatical sentences [2]. Recently, Duchier et al. [3] proposed a model-theoretic(More)
In this paper we present a parsing architecture that allows processing of different mildly context-sensitive formalisms, in particular Tree-Adjoining Grammar (TAG), Multi-Component Tree-Adjoining Grammar with Tree Tuples (TT-MCTAG) and simple Range Concatenation Grammar (RCG). Furthermore, for tree-based grammars, the parser computes not only syntactic(More)
In this paper, we introduce SEMTAG, a free and open software architecture for the development of Tree Adjoining Grammars integrating a compositional semantics. SEM-TAG differs from XTAG in two main ways. First, it provides an expressive grammar formalism and compiler for factorising and specifying TAGs. Second, it supports semantic construction.
