Semantic Frame-Based Spoken Language Understanding [chapter]

Ye-Yi Wang, Li Deng, Alex Acero
2011 Spoken Language Understanding  
A frame-based SLU system is often limited to a specific domain, which has a well-defined, relatively small semantic space.  ...  It has been used in many speech language processing tasks, in particular the transactional dialog systems, where various pieces of information need to be collected from users.  ...  On the other hand, the domain-specific semantic content of a sentence is completely encoded by the lower level semantic non-terminals (categories) in the parse tree, thus making it feasible to extract  ...

Comparison of Syntactic Parsers on Biomedical Texts [article]

Maria Biryukov
2020 arXiv   pre-print
Quality of the syntactic parsing determines to a large extent the recall and precision of the text mining results.  ...  Syntactic parsing is an important step in the automated text analysis which aims at information extraction.  ...  In the last years many high quality syntactic parsers became publicly available leading to a natural question of choice of the best and most appropriate one for a specific task.  ...

Taking advantage of the situation

Michael Fleischman, Eduard Hovy
2006 Proceedings of the 11th international conference on Intelligent user interfaces - IUI '06  
This situation model is integrated with a model of word meaning in a principled manner using a noisy channel approach to language understanding.  ...  We introduce a framework for learning situated Natural Language Interfaces (NLIs) to interactive virtual environments.  ...  Finally, we thank Deb Roy, who was essential to the development of the ideas presented here.  ...

Cross-Domain Effects on Parse Selection for Precision Grammars

Andrew MacKinlay, Rebecca Dridan, Dan Flickinger, Timothy Baldwin
2010 Research on Language and Computation  
We examine the impact of domain on parse selection accuracy, in the context of precision HPSG parsing using the English Resource Grammar, using two training corpora and four test corpora and evaluating  ...  of the same size, but we verify experimentally that this holds for a handcrafted grammar, observing a 10-16% improvement in exact match and 5-6% improvement in dependency F-score by using a domain-matched  ...  Much of this previous work has looked at parsing with treebank-derived grammars, and it is not clear how applicable the results are to the scenario of parsing with hand-crafted precision grammars.  ...

2015 2015 IEEE International Symposium on Performance Analysis of Systems and Software (ISPASS)  
To inject knowledge, we use a state-of-the-art system which cross-links (or "grounds") expressions in free text to Wikipedia.  ...  Our end system outperforms the state-of-the-art baseline by 2 B 3 F1 points on non-transcript portion of the ACE 2004 dataset.  ...  We incorporate an inductive bias into grammar learning in favor of grammars that lead to unambiguous parses on natural language sentences.  ...

Semantic language models with deep neural networks

Ali Orkan Bayer, Giuseppe Riccardi
2016 Computer Speech and Language  
Spoken language systems (SLS) communicate with users in natural language through speech. There are two main problems related to processing the spoken input in SLS.  ...  LMs constrain the search space that is used in the search for the best hypothesis. Therefore, they play a crucial role in the performance of SLS. 6 1.4. STRUCTURE OF THE THESIS  ...  Knowledge-based approaches are based on hand-crafted grammars and not in the scope of this thesis.  ...

AutoTutor and Family: A Review of 17 Years of Natural Language Tutoring

Benjamin D. Nye, Arthur C. Graesser, Xiangen Hu
2014 International Journal of Artificial Intelligence in Education  
AutoTutor is a natural language tutoring system that has produced learning gains across multiple domains (e.g., computer literacy, physics, critical thinking).  ...  The latter findings include the effectiveness of deep reasoning questions for tutoring multiple domains, of adapting to the affect of low-knowledge learners, of content over surface features such as voices  ...  Any opinions, findings, and conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of these funding sources.  ...
