HPSG

The lexicon now plays a central role in our imple- mentation of a Head-driven Phrase Structure Grammar (HPSG), given the massive relocation into the lexicon of linguistic information that was …...

In this paper we present a formalization of the center- ing approach to modeling attentional structure in dis- course and use it as the basis for an algorithm to track …...

This paper presents a unification-based approach to Japanese honorifics based on a version of HPSG (Head-driven Phrase Structure Grammar)ll]121. Utterance parsing is based on lexical specifications of each lexical item, …...

I describe a head-driven parser for a class of gram- mars that handle discontinuous constituency by a richer notion of string combination than ordinary concatenation. The parser is a generalization …...

We investigate the logical structure of concepts generated by conjunction and disjunction over a monotonic multiple inheritance network where concept nodes represent linguistic categories and links indicate basic inclusion (ISA) …...

Linear precedence (LP) rules are widely used for stating word order principles. They have been adopted as constraints by HPSG but no encoding in the formalism has been provided. Since …...

This paper presents Trace & Unification Grammar (TUG), a declarative and reversible grammar formal- ism that brings together Unification Grammar (UG) and ideas of Government & Binding Theory (on)~ The …...

AbstractIn this paper, we introduce the methodology for the construction of dictionary fragments under development in DELIS. The approach advocated is corpus-based, computationally supported, and aimed at the construction of …...

The interpretation of coercion construc- tions (to begin a book) has been recently considered as resulting from the operation of type changing. For instance, a phrase of type o (object) …...

This paper provides a model theoretic semantics to fea- ture terms augmented with set descriptions. We pro- vide constraints to specify HPSG style set descriptions, fixed cardinality set descriptions, set-membership …...

The paper describes a parser for Catego- rial Grammar which provides fully word by word incremental interpretation. The parser does not require fragments of sen- tences to form constituents, and …...

A novel approach to HPSG based natural language processing is described that uses an off-line compiler to automatically prime a declarative grammar for generation or parsing, and inputs the primed …...

The paper presents a constraint based semantic formalism for HPSG. The syntax-semantics inter- face directly implements syntactic conditions on quantifier scoping and distributivity. 1 The con- struction of semantic representations …...

German is a language with a relatively free word order. During the last few years considerable efforts have been made in all syntactic frameworks to explain so-called scrambling phenomena. In …...

In this paper we provide a probabilis- tic interpretation for typed feature struc- tures very similar to those used by Pol- lard and Sag. We begin with a ver- sion …...

We propose a treatment of coordination based on the concepts of functor, argument and subcategorization. Its formalization comprises two parts which are conceptually independent. On one hand, we have ex- …...

This paper describes results achieved in a project which addresses the issue of how the gap between unification-based grammars as a scientific concept and real world applications can be narrowed …...

We propose a parser for constraint- logic grammars implementing HPSG that combines the advantages of dy- namic bottom-up and advanced top- down control. The parser allows the user to apply …...

We present a solution for the representation of Japanese honorificational information in the HPSG framework. Basically, there are three dimensions of honorification. We show that a treatment is necessary that …...

This paper considers three assumptions conventionally made about signatures in typed feature logic that are in po- tential disagreement with current prac- tice among grammar developers and linguists working within …...

This paper examines feature selection for log linear models over rich constraint-based grammar (HPSG) representations by building decision trees over fea- tures in corresponding probabilistic context free grammars (PCFGs). We …...

This paper describes new default unification, lenient default unification. It works efficiently, and gives more informative results because it maximizes the amount of information in the result, while other de- …...

Minimal Recursion Semantics (MRS) is the standard formalism used in large-scale HPSG grammars to model underspecified semantics. We present the first provably efficient algorithm to enumerate the read- ings of …...

We extend Combinatory Categorial Grammar (CCG) with a generalized notion of multi- dimensional sign, inspired by the types of rep- resentations found in constraint-based frame- works like HPSG or LFG. …...

This paper introduces an indexing method based on static analysis of grammar rules and type signatures for typed feature structure grammars (TFSGs). The static analysis tries to predict at compile-time …...

We propose a conditional random field- based method for supertagging, and ap- ply it to the task of learning new lexi- cal items for HPSG-based precision gram- mars of English …...

This paper proposes a generic mathemati- cal formalism for the combination of various structures: strings, trees, dags, graphs and products of them. The polari- zation of the objects of the …...

Syntactic analysis is a fundamental phase in NLP (Natural Language Processing) do- main. This phase occurs in several applica- tions and at different levels. Moreover, it wasn’t spilled in domain …...

When designing grammars of natural lan- guage, typically, more than one formal anal- ysis can account for a given phenomenon. Moreover, because analyses interact, the choices made by the engineer …...

AbstractWe present the ongoing development of MCG, a linguistically deep and precise grammar for Mandarin Chinese together with its accompanying treebank, both based on the linguistic framework of HPSG, and …...

This paper reports on an implementation of a multimodal grammar of speech and co-speech gesture within the LKB/PET grammar engi- neering environment. The implementation ex- tends the English Resource Grammar …...

In this paper, we consider the problem of cross-formalism transfer in parsing. We are interested in parsing constituency- based grammars such as HPSG and CCG using a small amount of …...

AbstractThis paper compares a recent TAG-based analysis of complex predicates in Hindi/Urdu with its HPSG analog. It points out that TAG combines actual structure while HPSG (and Categorial Grammar and …...

AbstractHead-driven phrase structure grammar (HPSG) enjoys a uniform formalism representing rich contextual syntactic and even semantic meanings. This paper makes the first attempt to formulate a simplified HPSG by integrating …...
