A formal frame for robust parsing

M. Vilares, V.M. Darriba, J. Vilares, F.J. Ribadas
2004 Theoretical Computer Science  
A robust parser for context-free grammars, based on a dynamic programming architecture, is described.  ...  Experimental tests prove the validity of the approach, illustrating the perspectives for its application in real systems over a variety of different situations, as well as the causes underlying the computational  ...  We concentrate on enhancing robustness by using the mechanisms offered by dynamic programming in order to improve performance and provide a formal parse definition.  ...

Parsing engineering and empirical robustness

ROBERTO BASILI, FABIO MASSIMO ZANZOTTO
2002 Natural Language Engineering  
In this paper, we propose an empirical definition of robustness based on the notion of performance. Furthermore, a framework for controlling the parser robustness in the design phase is presented.  ...  The methodology has been adopted for the production of CHAOS, a pool of syntactic modules, which has been used in real applications.  ...  All the tests suggested that architectural issues play a critical role on robustness (at least for parsing).  ...

Logical Approach to Natural Language Understanding in a Spoken Dialogue System [chapter]

Jeanne Villaneau, Jean-Yves Antoine, Olivier Ridoux
2004 Lecture Notes in Computer Science  
We present a logical approach of spoken language understanding for a human-machine dialogue system.  ...  This approach is a preliminary for a logical dialogue that uses the form of the semantic representations. 3  ...  LOGUS was assessed on a set of 1200 tests which have shown the efficiency of the approach: the robustness of the parsing is satisfactory (error rate lower than 10%) and the system is able to build precise  ...

PROFER: predictive, robust finite-state parsing for spoken language

E.C. Kaiser, M. Johnston, P.A. Heeman
1999 1999 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings. ICASSP99 (Cat. No.99CH36258)  
In contrast, we are developing a robust, semantic parser that is a single, predictive finite-state machine.  ...  The natural language processing component of a speech understanding system is commonly a robust, semantic parser, implemented as either a chart-based transition network, or as a generalized leftright (  ...  And at the semantic level the PHOENIX system has been used for robust "concept-spotting" [12] . PHOENIX works by filling slots within a case-frame.  ...

Robust, finite-state parsing for spoken language understanding

Edward C. Kaiser
1999 Proceedings of the 37th annual meeting of the Association for Computational Linguistics on Computational Linguistics -  
One reason for this is the complexity of implementing that integration. To address this issue we have created a robust, semantic parser as a single finite-state machine (FSM).  ...  As such, its run-time action is less complex than other robust parsers that are based on either chart or generalized left-right (GLR) architectures.  ...  We also wish to thank Peter Heeman and Michael Johnston for valuable discussions and support.  ...

Recent Advances in JANUS: A Speech Translation System [chapter]

A. Waibel, M. Woszczyna
1995 Speech Recognition and Coding  
It has initially been built based on a speech database of i 2 read dialogs, encompassing a vocabulary of around 500 words.  ...  We present recent advances from our efforts in increasing coverage, robustness, generality and speed of JANUS, CMU's speech-tospeech translation system.  ...  A grammar with about 455 rules for general colloquial English is written in a Pseudo Unification formalism [15] , that is similar to Unification Grammar and LFG formalisms.  ...
