META: Metadata-Empowered Weak Supervision for Text Classification

1 code implementation EMNLP 2020 Dheeraj Mekala, Xinyang Zhang, Jingbo Shang

Based on seed words, we rank and filter motif instances to distill highly label-indicative ones as {``}seed motifs{''}, which provide additional weak supervision.

Intermediate Training on Question Answering Datasets Improves Generative Data Augmentation

no code implementations25 May 2022 Dheeraj Mekala, Tu Vu, Jingbo Shang

We improve generative data augmentation by formulating the data generation as context generation task and use question answering (QA) datasets for intermediate training.

Coarse2Fine: Fine-grained Text Classification on Coarsely-grained Annotated Data

no code implementations EMNLP 2021 Dheeraj Mekala, Varun Gangal, Jingbo Shang

Existing text classification methods mainly focus on a fixed label set, whereas many real-world applications require extending to new fine-grained classes as the number of samples per label increases.

BFClass: A Backdoor-free Text Classification Framework

no code implementations Findings (EMNLP) 2021 Zichao Li, Dheeraj Mekala, chengyu dong, Jingbo Shang

To recognize the poisoned subset, we examine the training samples with these identified triggers as the most suspicious token, and check if removing the trigger will change the poisoned model's prediction.

News Meets Microblog: Hashtag Annotation via Retriever-Generator

1 code implementation18 Apr 2021 Xiuwen Zheng, Dheeraj Mekala, Amarnath Gupta, Jingbo Shang

Hashtag annotation for microblog posts has been recently formulated as a sequence generation problem to handle emerging hashtags that are unseen in the training set.

Contextualized Weak Supervision for Text Classification

1 code implementation ACL 2020 Dheeraj Mekala, Jingbo Shang

Weakly supervised text classification based on a few user-provided seed words has recently attracted much attention from researchers.

SCDV : Sparse Composite Document Vectors using soft clustering over distributional representations

4 code implementations EMNLP 2017 Dheeraj Mekala, Vivek Gupta, Bhargavi Paranjape, Harish Karnick

We present a feature vector formation technique for documents - Sparse Composite Document Vector (SCDV) - which overcomes several shortcomings of the current distributional paragraph vector representations that are widely used for text representation.
