Large Language Models on Wikipedia-Style Survey Generation: an Evaluation in NLP Concepts

1 code implementation21 Aug 2023 Fan Gao, Hang Jiang, Rui Yang, Qingcheng Zeng, Jinghui Lu, Moritz Blum, Dairui Liu, Tianwei She, Yuang Jiang, Irene Li

Educational materials such as survey articles in specialized fields like computer science traditionally require tremendous expert inputs and are therefore expensive to create and update.

ConGraT: Self-Supervised Contrastive Pretraining for Joint Graph and Text Embeddings

1 code implementation23 May 2023 William Brannon, Suyash Fulay, Hang Jiang, Wonjune Kang, Brandon Roy, Jad Kabbara, Deb Roy

We propose ConGraT(Contrastive Graph-Text pretraining), a general, self-supervised method for jointly learning separate representations of texts and nodes in a parent (or ``supervening'') graph, where each text is associated with one of the nodes.

PersonaLLM: Investigating the Ability of Large Language Models to Express Personality Traits

1 code implementation4 May 2023 Hang Jiang, Xiajie Zhang, Xubo Cao, Cynthia Breazeal, Deb Roy, Jad Kabbara

Despite the many use cases for large language models (LLMs) in creating personalized chatbots, there has been limited research on evaluating the extent to which the behaviors of personalized LLMs accurately and consistently reflect specific personality traits.

CommunityLM: Probing Partisan Worldviews from Language Models

1 code implementation COLING 2022 Hang Jiang, Doug Beeferman, Brandon Roy, Deb Roy

As political attitudes have diverged ideologically in the United States, political speech has diverged lingusitically.

Using Twitter Data to Understand Public Perceptions of Approved versus Off-label Use for COVID-19-related Medications

1 code implementation29 Jun 2022 Yining Hua, Hang Jiang, Shixu Lin, Jie Yang, Joseph M. Plasek, David W. Bates, Li Zhou

Time-trend analysis indicated that Hydroxychloroquine and Ivermectin were discussed more than Molnupiravir and Remdesivir, particularly during COVID-19 surges.

Topic Detection and Tracking with Time-Aware Document Embeddings

no code implementations12 Dec 2021 Hang Jiang, Doug Beeferman, Weiquan Mao, Deb Roy

TDT systems aim to cluster a corpus of news articles by event, and in that context, stories that describe the same event are likely to have been written at around the same time.

Topic-time Heatmaps for Human-in-the-loop Topic Detection and Tracking

no code implementations12 Oct 2021 Doug Beeferman, Hang Jiang

The essential task of Topic Detection and Tracking (TDT) is to organize a collection of news media into clusters of stories that pertain to the same real-world event.

LNN-EL: A Neuro-Symbolic Approach to Short-text Entity Linking

1 code implementation ACL 2021 Hang Jiang, Sairam Gurajada, Qiuhao Lu, Sumit Neelam, Lucian Popa, Prithviraj Sen, Yunyao Li, Alexander Gray

Entity linking (EL), the task of disambiguating mentions in text by linking them to entities in a knowledge graph, is crucial for text understanding, question answering or conversational systems.

Contrastive Learning of Medical Visual Representations from Paired Images and Text

7 code implementations2 Oct 2020 Yuhao Zhang, Hang Jiang, Yasuhide Miura, Christopher D. Manning, Curtis P. Langlotz

Existing work commonly relies on fine-tuning weights transferred from ImageNet pretraining, which is suboptimal due to drastically different image characteristics, or rule-based label extraction from the textual report data paired with medical images, which is inaccurate and hard to generalize.

Data augmentation with Mobius transformations

1 code implementation7 Feb 2020 Sharon Zhou, Jiequan Zhang, Hang Jiang, Torbjorn Lundh, Andrew Y. Ng

Data augmentation has led to substantial improvements in the performance and generalization of deep models, and remain a highly adaptable method to evolving model architectures and varying amounts of data---in particular, extremely scarce amounts of available training data.

DialectGram: Detecting Dialectal Variation at Multiple Geographic Resolutions

1 code implementation4 Oct 2019 Hang Jiang, Haoshen Hong, Yuxing Chen, Vivek Kulkarni

In this work, we propose a model that enables detection of dialectal variation at multiple levels of geographic resolution obviating the need for a-priori definition of the resolution level.
