ACL 20232023Dialect differences caused by regional, social, and economic factors cause performance discrepancies for many groups of language technology users. Inclusive and equitable language technology must critically be dialect invariant, meaning that performance remains constant over dialectal shifts. Current systems often fall short of this ideal since they are designed and tested on a single dialect: Standard

ACL 2023 Workshop on SustaiNLP2023Prompting is a widely adopted technique for fine-tuning large language models. Recent research by Scao and Rush (2021) has demonstrated its effectiveness in improving few-shot learning performance compared to vanilla fine-tuning and also showed that prompting and vanilla fine tuning achieves similar performance in high data regime (∼> 2000 samples). This paper investigates the impact of imbalanced data

ICLR 2023 Workshop on Practical Machine Learning for Developing Countries (PML4DC)2023Language model based methods are powerful techniques for text classification. However, the models have several shortcomings. (1) It is difficult to integrate human knowledge such as keywords. (2) It needs a lot of resources to train the models. (3) It relied on large text data to pretrain. In this paper, we propose Semi-Supervised vMF Neural Topic Modeling (S2vNTM) to overcome these difficulties. S2vNTM

KDD 20232023Graph Neural Networks (GNNs) have achieved great success in modeling graph-structured data. However, recent works show that GNNs are vulnerable to adversarial attacks which can fool the GNN model to make desired predictions of the attacker. In addition, training data of GNNs can be leaked under membership inference attacks. This largely hinders the adoption of GNNs in high-stake domains such as e-commerce

ACL 2023 Workshop on Natural Language Reasoning and Structured Explanations2023Large language models have shown impressive abilities to reason over input text, however, they are prone to hallucinations. On the other hand, end-to-end knowledge graph question answering (KGQA) models output responses grounded in facts, but they still struggle with complex reasoning, such as comparison or ordinal questions. In this paper, we propose a new method for complex question answering where we
