Retrieval as Attention: End-to-end Learning of Retrieval and Reading within a Single Transformer

1 code implementation5 Dec 2022 Zhengbao Jiang, Luyu Gao, Jun Araki, Haibo Ding, Zhiruo Wang, Jamie Callan, Graham Neubig

Systems for knowledge-intensive tasks such as open-domain question answering (QA) usually consist of two stages: efficient retrieval of relevant documents from a large corpus and detailed reading of the selected documents to generate answers.

Understanding and Improving Zero-shot Multi-hop Reasoning in Generative Question Answering

no code implementations COLING 2022 Zhengbao Jiang, Jun Araki, Haibo Ding, Graham Neubig

In sum, these results demonstrate that multi-hop reasoning does not emerge naturally in generative QA models, but can be encouraged by advances in training or modeling techniques.

Explicitly Capturing Relations between Entity Mentions via Graph Neural Networks for Domain-specific Named Entity Recognition

1 code implementation ACL 2021 Pei Chen, Haibo Ding, Jun Araki, Ruihong Huang

Named entity recognition (NER) is well studied for the general domain, and recent systems have achieved human-level performance for identifying common entity types.

GLaRA: Graph-based Labeling Rule Augmentation for Weakly Supervised Named Entity Recognition

1 code implementation EACL 2021 Xinyan Zhao, Haibo Ding, Zhe Feng

Instead of using expensive manual annotations, researchers have proposed to train named entity recognition (NER) systems using heuristic labeling rules.

How Can We Know When Language Models Know? On the Calibration of Language Models for Question Answering

1 code implementation2 Dec 2020 Zhengbao Jiang, Jun Araki, Haibo Ding, Graham Neubig

We examine this question from the point of view of calibration, the property of a probabilistic model's predicted probabilities actually being well correlated with the probabilities of correctness.

Learning to Classify Events from Human Needs Category Descriptions

no code implementations Findings of the Association for Computational Linguistics 2020 Haibo Ding, Zhe Feng

We study the problem of learning an event classifier from human needs category descriptions, which is challenging due to: (1) the use of highly abstract concepts in natural language descriptions, (2) the difficulty of choosing key concepts.

X-FACTR: Multilingual Factual Knowledge Retrieval from Pretrained Language Models

1 code implementation EMNLP 2020 Zhengbao Jiang, Antonios Anastasopoulos, Jun Araki, Haibo Ding, Graham Neubig

We further propose a code-switching-based method to improve the ability of multilingual LMs to access knowledge, and verify its effectiveness on several benchmark languages.
