Incremental Few-shot Text Classification with Multi-round New Classes: Formulation, Dataset and System

1 code implementation NAACL 2021 Congying Xia, Wenpeng Yin, Yihao Feng, Philip Yu

Two major challenges exist in this new task: (i) For the learning process, the system should incrementally learn new classes round by round without re-training on the examples of preceding classes; (ii) For the performance, the system should perform well on new classes without much loss on preceding classes.

Paired Representation Learning for Event and Entity Coreference

no code implementations24 Oct 2020 Xiaodong Yu, Wenpeng Yin, Dan Roth

Given a pair of elements (Events or Entities) our model treats the pair's sentences as a single sequence so that each element in the pair learns its representation by encoding its own context as well the other element's context.

Universal Natural Language Processing with Limited Annotations: Try Few-shot Textual Entailment as a Start

1 code implementation EMNLP 2020 Wenpeng Yin, Nazneen Fatema Rajani, Dragomir Radev, Richard Socher, Caiming Xiong

We demonstrate that this framework enables a pretrained entailment model to work well on new entailment domains in a few-shot setting, and show its effectiveness as a unified solver for several downstream NLP tasks such as question answering and coreference resolution when the end-task annotations are limited.

Mixup-Transformer: Dynamic Data Augmentation for NLP Tasks

no code implementations5 Oct 2020 Lichao Sun, Congying Xia, Wenpeng Yin, TingTing Liang, Philip S. Yu, Lifang He

Our studies show that mixup is a domain-independent data augmentation technique to pre-trained language models, resulting in significant performance improvement for transformer-based models.

TwoWingOS: A Two-Wing Optimization Strategy for Evidential Claim Verification

no code implementations EMNLP 2018 Wenpeng Yin, Dan Roth

We develop TwoWingOS (two-wing optimization strategy), a system that, while identifying appropriate evidence for a claim, also determines whether or not the claim is supported by the evidence.

Term Definitions Help Hypernymy Detection

no code implementations SEMEVAL 2018 Wenpeng Yin, Dan Roth

Existing methods of hypernymy detection mainly rely on statistics over a big corpus, either mining some co-occurring patterns like "animals such as cats" or embedding words of interest into context-aware vectors.

Attentive Convolution: Equipping CNNs with RNN-style Attention Mechanisms

1 code implementation TACL 2018 Wenpeng Yin, Hinrich Schütze

We hypothesize that this is because the attention in CNNs has been mainly implemented as attentive pooling (i. e., it is applied to pooling) rather than as attentive convolution (i. e., it is integrated into convolution).

Task-Specific Attentive Pooling of Phrase Alignments Contributes to Sentence Matching

no code implementations EACL 2017 Wenpeng Yin, Hinrich Schütze

This work studies comparatively two typical sentence matching tasks: textual entailment (TE) and answer selection (AS), observing that weaker phrase alignments are more critical in TE, while stronger phrase alignments deserve more attention in AS.

Simple Question Answering by Attentive Convolutional Neural Network

no code implementations COLING 2016 Wenpeng Yin, Mo Yu, Bing Xiang, Bo-Wen Zhou, Hinrich Schütze

In fact selection, we match the subject entity in a fact candidate with the entity mention in the question by a character-level convolutional neural network (char-CNN), and match the predicate in that fact with the question by a word-level CNN (word-CNN).
