The paper describes a formal theory for the dependency approach to syntax. The formalism is able to deal with long-distance dependencies, involved in function sharing and extractions. The distinctive aspects of the approach are the use of non lexical categories and a GPSG-style treatment of long-distance dependencies. The formalism is applied to a number of coordination phenomena, that are well...

In this paper, we discuss the use of the Meaning-Text Theory (MTT) of [Mel88] in a controlled language (CL) application. We show that MTT defines a linguistic framework which is ideally suited for the definition and automation of CL rules. In the paper, we first briefly present a CL system based on MTT. We then discuss MTT in more detail. We show how CL-specific information can be represented s...

We study the performance of Arabic text classification combining various techniques: (a) tfidf vs. dependency syntax, for feature selection and weighting; (b) class association rules vs. support vector machines, for classification. The Arabic text is used in two forms: rootified and lightly stemmed. The results we obtain show that lightly stemmed text leads to better performance than rootified ...

Recent research has shown clear improvement in translation quality by exploiting linguistic syntax for either the source or target language. However, when using syntax for both languages (“tree-to-tree” translation), there is evidence that syntactic divergence can hamper the extraction of useful rules (Ding and Palmer 2005). Smith and Eisner (2006) introduced quasi-synchronous grammar, a formal...

This paper approaches the challenge of adapting coreference resolution to different coreference phenomena and mention-border definitions when there is no access to large training data in the desired target scheme. We take a configurable, rule-based approach centered on dependency syntax input, which we test by examining coreference types not covered in benchmark corpora such as OntoNotes. These...

We address the question what it takes to define a correct probabilistic model for syntactic natural language processing. We focus on one particular theory of syntax, called dependency syntax, and develop a framework for developing probabilistic model for that linguistic theory. Subsequently, we review existing models of probabilistic dependency syntax and show some problematic aspects of these ...

Chalmers’s philosophical work exploits a distinctive version of two-dimensionalism, a formal modal framework from the 1960s and 1970s that one can use to define two kinds of possible worlds semantic values. Chalmers presents this as the best form of a Fregean account of content. One of the principal aims of Constructing the World is to provide its metaphysical foundations. Chalmers presents him...

From the parsing point of view, the derivation tree in TAG [hereafter DT] is seen as the "history" of the derivation but also as a linguistic representation, closer to semantics, that can be the basis of a further analysis. Because in TAG the elementary trees are lexicalized and localize the predicate-arguments relations, several works have compared the DT to a structure involving dependencies ...
