Few-shot Slot Tagging with Collapsed Dependency Transfer and Label-enhanced Task-adaptive Projection Network [PDF]
Annual Meeting of the Association for Computational Linguistics, 2020 In this paper, we explore the slot tagging with only a few labeled support sentences (a.k.a. few-shot). Few-shot slot tagging faces a unique challenge compared to the other fewshot classification problems as it calls for modeling the dependencies between

Graph Convolution over Pruned Dependency Trees Improves Relation Extraction [PDF]
Conference on Empirical Methods in Natural Language Processing, 2018 Dependency trees help relation extraction models capture long-range relations between words. However, existing dependency-based models either neglect crucial information (e.g., negation) by pruning the dependency trees too aggressively, or are ...

Dependence and Independence [PDF]
Studia Logica, 2013 We introduce an atomic formula intuitively saying that given variables are independent from given other variables if a third set of variables is kept constant. We contrast this with dependence logic. We show that our independence atom gives rise to a natural logic capable of formalizing basic intuitions about independence and dependence.

Dependency Graph Enhanced Dual-transformer Structure for Aspect-based Sentiment Classification
Annual Meeting of the Association for Computational Linguistics, 2020 Aspect-based sentiment classification is a popular task aimed at identifying the corresponding emotion of a specific aspect. One sentence may contain various sentiments for different aspects.

Evaluating Factuality in Generation with Dependency-level Entailment [PDF]
Findings, 2020 Despite significant progress in text generation models, a serious limitation is their tendency to produce text that is factually inconsistent with information in the input.

Defining a Cancer Dependency Map
Cell, 2017 SUMMARY Most human epithelial tumors harbor numerous alterations, making it difficult to predict which genes are required for tumor survival. To systematically identify cancer dependencies, we analyzed 501 genome-scale loss-of-function screens performed ...

Dependency-driven Relation Extraction with Attentive Graph Convolutional Networks
Annual Meeting of the Association for Computational Linguistics, 2021 Syntactic information, especially dependency trees, has been widely used by existing studies to improve relation extraction with better semantic guidance for analyzing the context information associated with the given entities.

A Dependent Dependency Calculus (Extended Version)
CoRR, 2022 Over twenty years ago, Abadi et al. established the Dependency Core Calculus (DCC) as a general purpose framework for analyzing dependency in typed programming languages. Since then, dependency analysis has shown many practical benefits to language design: its results can help users and compilers enforce security constraints, eliminate dead code, among

Feature-Rich Part-of-Speech Tagging with a Cyclic Dependency Network
North American Chapter of the Association for Computational Linguistics, 2003 We present a new part-of-speech tagger that demonstrates the following ideas: (i) explicit use of both preceding and following tag contexts via a dependency network representation, (ii) broad use of lexical features, including jointly conditioning on ...

WNT as a driver and dependency in cancer
Cancer Discovery, 2021 The WNT signaling pathway is a critical regulator of development and adult tissue homeostasis and becomes dysregulated in many cancer types. While hyperactivation of WNT signaling is common, the type and frequency of genetic WNT pathway alterations can ...
