Formalization and Parsing of Typed Unification-Based ID/LP GrammarsThis paper defines unification based ID/LP grammars based on typed feature structures as nonterminals and proposes a variant of Earley's algorithm to decide whether a given input sentence is a…Frank Morawietz·Feb 14, 1995SaveLearn
A syntax-based part-of-speech analyserThere are two main methodologies for constructing the knowledge base of a natural language analyser: the linguistic and the data-driven. Recent state-of-the-art part-of-speech taggers are based on…Atro Voutilainen·Feb 13, 1995SaveLearn
The Semantics of Resource Sharing in Lexical-Functional GrammarWe argue that the resource sharing that is commonly manifest in semantic accounts of coordination is instead appropriately handled in terms of structure-sharing in LFG f-structures. We provide an…Andrew Kehler, Mary Dalrymple, John Lamping et al.·Feb 13, 1995SaveLearn
Ellipsis and Quantification: a substitutional approachThe paper describes a substitutional approach to ellipsis resolution giving comparable results to Dalrymple, Shieber and Pereira (1991), but without the need for order-sensitive interleaving of…Richard Crouch·Feb 13, 1995SaveLearn
Ambiguity resolution in a reductionistic parserWe are concerned with dependency-oriented morphosyntactic parsing of running text. While a parsing grammar should avoid introducing structurally unresolvable distinctions in order to optimise on the…Atro Voutilainen, Pasi Tapanainen·Feb 13, 1995SaveLearn
Specifying a shallow grammatical representation for parsing purposesIs it possible to specify a grammatical representation (descriptors and their application guidelines) to such a degree that it can be consistently applied by different grammarians e.g. for producing…Atro Voutilainen, Timo Jarvinen·Feb 13, 1995SaveLearn

A Robust and Efficient Three-Layered Dialogue Component for a Speech-to-Speech Translation SystemWe present the dialogue component of the speech-to-speech translation system VERBMOBIL. In contrast to conventional dialogue systems it mediates the dialogue while processing maximally 50% of the…Jan Alexandersson, Elisabeth Maier, Norbert Reithinger·Feb 10, 1995SaveLearn
On Learning More Appropriate Selectional RestrictionsWe present some variations affecting the association measure and thresholding on a technique for learning Selectional Restrictions from on-line corpora. It uses a wide-coverage noun taxonomy and a…Francesc Ribas·Feb 9, 1995SaveLearn
Utilization of a Lexicon for Spelling Correction in Modern GreekIn this paper we present an interactive spelling correction system for Modern Greek. The entire system is based on a morphological lexicon. Emphasis is given to the development of the lexicon,…A. Vagelatos, T. Triantopoulou, C. Tsalidis et al.·Feb 9, 1995SaveLearn
Rapid Development of Morphological Descriptions for Full Language Processing SystemsI describe a compiler and development environment for feature-augmented two-level morphology rules integrated into a full NLP system. The compiler is optimized for a class of languages including many…David Carter·Feb 8, 1995SaveLearn
Off-line Optimization for Earley-style HPSG ProcessingA 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…Guido Minnen, Dale Gerdemann, Thilo Goetz·Feb 7, 1995SaveLearn
Bottom-Up Earley DeductionWe propose a bottom-up variant of Earley deduction. Bottom-up deduction is preferable to top-down deduction because it allows incremental processing (even for head-driven grammars), it is…Gregor Erbach·Feb 5, 1995SaveLearn
