CQR-SQL: Conversational Question Reformulation Enhanced Context-Dependent Text-to-SQL Parsers [article]

Dongling Xiao, Linzheng Chai, Qian-Wen Zhang, Zhao Yan, Zhoujun Li, Yunbo Cao
2022 arXiv   pre-print
In this paper, we propose CQR-SQL, which uses auxiliary Conversational Question Reformulation (CQR) learning to explicitly exploit schema and decouple contextual dependency for SQL parsing.  ...  Secondly, we train CQR-SQL models to map the semantics of multi-turn questions and auxiliary self-contained questions into the same latent space through schema grounding consistency task and tree-structured  ...  For context-dependent text-to-SQL, it is common to train a model in an end-to-end manner.  ...

Dependency Parsing

Sandra Kübler, Ryan McDonald, Joakim Nivre
2009 Synthesis Lectures on Human Language Technologies  
After an introduction to dependency grammar and dependency parsing, followed by a formal characterization of the dependency parsing problem, the book surveys the three major classes of parsing models that  ...  This book gives a thorough introduction to the methods that are most widely used today.  ...  Memory-based classifiers are very efficient to train, since learning only consists in storing the training instances for efficient retrieval.  ...

Context Dependent Semantic Parsing: A Survey [article]

Zhuang Li, Lizhen Qu, Gholamreza Haffari
2020 arXiv   pre-print
To address this issue, context dependent semantic parsing has recently drawn a lot of attention.  ...  Currently, most semantic parsing methods are not able to utilize contextual information (e.g. dialogue and comments history), which has a great potential to boost semantic parsing performance.  ...  Acknowledgements We thank Xuanli He and anonymous reviewers for their useful suggestions.  ...

Semantic Role Labeling as Syntactic Dependency Parsing [article]

Tianze Shi, Igor Malioutov, Ozan İrsoy
2020 arXiv   pre-print
Based on this observation, we present a conversion scheme that packs SRL annotations into dependency tree representations through joint labels that permit highly accurate recovery back to the original  ...  This representation allows us to train statistical dependency parsers to tackle SRL and achieve competitive performance with the current state of the art.  ...  Tsai for discussion and comments.  ...

Learning Dependency-Based Compositional Semantics [article]

Percy Liang and Michael I. Jordan and Dan Klein
2011 arXiv   pre-print
Our goal is to learn a semantic parser from question-answer pairs instead, where the logical form is modeled as a latent variable.  ...  Suppose we want to build a system that answers a natural language question by representing its semantics as a logical form and computing the answer given a structured database of facts.  ...  Acknowledgments We thank Luke Zettlemoyer and Tom Kwiatkowski for providing us with data and answering questions.

Dependency Annotation Choices: Assessing Theoretical and Practical Issues of Universal Dependencies

Kim Gerdes, Sylvain Kahane
2016 Proceedings of the 10th Linguistic Annotation Workshop held in conjunction with ACL 2016 (LAW-X 2016)  
This article attempts to place dependency annotation options on a solid theoretical and applied footing.  ...  By verifying the validity of some basic choices of the current dependency reference framework, Universal Dependencies (UD), in a perspective of general annotation principles, we show how some choices can  ...  This also causes the parser to have more similar training examples and fewer ambiguities to resolve (precision).  ...

Yanzhao Zheng, Haibin Wang, Baohua Dong, Xingjun Wang, Changshan Li
2022 arXiv   pre-print
In view of the mismatch, we treat natural language and SQL as two modalities and propose a bimodal pre-trained model to bridge the gap between them.  ...  Recently, context-dependent text-to-SQL semantic parsing which translates natural language into SQL in an interaction process has attracted a lot of attention.  ...  to avoid leaking answers and help SQL-BERT learn the information structure of SQL better.  ...

Transforming Dependency Structures to Logical Forms for Semantic Parsing

Siva Reddy, Oscar Täckström, Michael Collins, Tom Kwiatkowski, Dipanjan Das, Mark Steedman, Mirella Lapata
2016 Transactions of the Association for Computational Linguistics  
In contrast-partly due to the lack of a strong type system-dependency structures are easy to annotate and have become a widely used form of syntactic analysis for many languages.  ...  Experiments on the Free917 and Web-Questions datasets show that our representation is superior to the original dependency trees and that it outperforms a CCG-based representation on this task.  ...  The authors would also like to thank Christopher Potts and the three anonymous reviewers for their valuable feedback.  ...

From Dependence to Causation [article]

2016 arXiv   pre-print
First, we develop a framework for the study of statistical dependence based on copulas and random features.  ...  Machine learning is the science of discovering statistical dependencies in data, and the use of those dependencies to perform predictions.  ...  Instead, these discriminative dependence methods summarize the dependence structure of a multivariate data set into a low-dimensional statistic that answers the question at hand.  ...

Temporal FiLM: Capturing Long-Range Sequence Dependencies with Feature-Wise Modulations [article]

Sawyer Birnbaum, Volodymyr Kuleshov, Zayd Enam, Pang Wei Koh, Stefano Ermon
2021 arXiv   pre-print
Learning representations that accurately capture long-range dependencies in sequential inputs -- including text, audio, and genomic data -- is a key problem in deep learning.  ...  Feed-forward convolutional models capture only feature interactions within finite receptive fields while recurrent architectures can be slow and difficult to train due to vanishing gradients.  ...  We train the model (with and without TFiLM layers) to fill in the missing values. We train for 50 epochs using the ADAM optimizer with a learning rate of 3 × 10 −4 .  ...
