Online statistics for a unification-based dialogue parser

Micha Elsner, Mary Swift, James Allen, Daniel Gildea
2005 Proceedings of the Ninth International Workshop on Parsing Technology - Parsing '05   unpublished
We describe a method for augmenting unification-based deep parsing with statistical methods. We extend and adapt the Bikel parser, which uses head-driven lexical statistics, to dialogue.  ...  We show that our augmented parser produces significantly fewer constituents than the baseline system and achieves comparable bracketing accuracy, even yielding slight improvements for longer sentences.  ...  The TRIPS parser (Allen et al., 1996) is a unification parser using an HPSG-inspired grammar and hand-tuned weights for each rule.  ...

A bag of useful techniques for efficient and robust parsing

Bernd Kiefer, Hans-Ulrich Krieger, John Carroll, Rob Malouf
1999 Proceedings of the 37th annual meeting of the Association for Computational Linguistics on Computational Linguistics -  
This paper describes new and improved techniques which help a unification-based parser to process input efficiently and robustly.  ...  In combination these methods result in a speed-up in parsing time of more than an order of magnitude. The methods are correct in the sense that none of them rule out legal rule applications.  ...  We also want to thank Nicolas Nicolov for reading a version of this paper. Stephan Oepen's and Mark-Jan Nederhof's fruitful comments have helped us a lot.  ...

Balancing Robustness and Efficiency in Unification-Augmented Context-Free Parsers for Large Practical Applications [chapter]

Carolyn Penstein Rosé, Alon Lavie
2001 Text, Speech and Language Technology  
We demonstrate how the combination of a beam search together with ambiguity packing and statistical disambiguation provide a flexible framework for achieving a good balance between robustness and efficiency  ...  Our investigations are based on experimental results and comparative performance evaluations of both parsers using a grammar for the spoken language ESST (English Spontaneous Scheduling Task) domain.  ...  Both parsers are based on a unification-augmented context-free grammar formalism.  ...

Charting the depths of robust speech parsing

W. Kasper, B. Kiefer, H. U. Krieger, C. J. Rupp, K. L. Worm
1999 Proceedings of the 37th annual meeting of the Association for Computational Linguistics on Computational Linguistics -  
We describe a novel method for coping with ungrammatical input based on the use of chart-like data structures, which permit anytime processing. Priority is given to deep syntactic analysis.  ...  Should this fail, the best partial analyses are selected, according to a shortest-paths algorithm, and assembled in a robust processing phase.  ...  Acknowledgments We would like to thank the anonymous ACL reviewers for their detailed comments.  ...

Grounding Strategic Conversation: Using Negotiation Dialogues to Predict Trades in a Win-Lose Game

Anaïs Cadilhac, Nicholas Asher, Farah Benamara, Alex Lascarides
2013 Conference on Empirical Methods in Natural Language Processing  
This paper describes a method that predicts which trades players execute during a winlose game.  ...  We compare our method against four baselines and show that tracking how preferences evolve through the dialogue and reasoning about equilibrium moves are both crucial to success.  ...  We based our study on a corpus collected using an online version of The Settlers of Catan.  ...

This bootstrapped grammar is intended to drive a graded-unification-based CCG parser which is currently under development.  ...  The next and most important stage of my work involves enriching a grammar with semantic information to guide the graded-unification-based parser.  ...  Areas of particular focus have included Markov models, text coding and compression, gambling and the stock market, Kolmogorov complexity theory, and the relationship between information theory and statistics  ...

Incremental Multimodal Interface for Human Robot Interaction

E Afshin Ameri, Batu Akan, Baran Çürüklü
2010 2010 IEEE 15th Conference on Emerging Technologies & Factory Automation (ETFA 2010)  
Face-to-face human communication is a multimodal and incremental process. Humans employ different information channels (modalities) for their communication.  ...  In this work we suggest a new method for implementing multimodal interfaces in HRI domain and present the method employed on an industrial robot.  ...  A sample design based on ADE for development of a "smart home" is then presented. Incremental parsers are also used for generating online feedback during conversational interaction by [28] .  ...
