Recently, emotion analysis has gained increased attention by NLP researchers due to its various applications in opinion mining, e-commerce, comprehensive search, healthcare, personalized recommendations and online education.
CUET-NLP@DravidianLangTech-ACL2022: Exploiting Textual Features to Classify Sentiment of Multimodal Movie Reviews
With the proliferation of internet usage, a massive growth of consumer-generated content on social media has been witnessed in recent years that provide people’s opinions on diverse issues.
Socially Constructed Treatment Plans: Analyzing Online Peer Interactions to Understand How Patients Navigate Complex Medical Conditions
In this study, we leverage content analysis of online discourse and ethnographic studies with clinicians and patient representatives to characterize how treatment plans for complex conditions are "socially constructed."
REGen: A Reliable Evaluation Framework for Generative Event Argument Extraction
To bridge this gap, we introduce Reliable Evaluation framework for Generative event argument extraction (REGen), a framework that better aligns with human judgment.
Explicit, Implicit, and Scattered: Revisiting Event Extraction to Capture Complex Arguments
First, implicit arguments are event arguments which are not explicitly mentioned in the text, but can be inferred through context.
A Thematic Framework for Analyzing Large-scale Self-reported Social Media Data on Opioid Use Disorder Treatment Using Buprenorphine Product
In this study, we propose a theme-based framework to curate and analyze large-scale data from social media to characterize self-reported treatment information needs (TINs).
Oscillations in neuronal activity: a neuron-centered spatiotemporal model of the Unfolded Protein Response in prion diseases
We find that oscillations are more pronounced when the S-clearance rate and S-diffusivity are small in comparison to the P-clearance rate and P-diffusivity, respectively.
Do LLMs Find Human Answers To Fact-Driven Questions Perplexing? A Case Study on Reddit
Large language models (LLMs) have been shown to be proficient in correctly answering questions in the context of online discourse.
Deciphering Hate: Identifying Hateful Memes and Their Targets
The dataset consists of 7, 148 memes with Bengali as well as code-mixed captions, tailored for two tasks: (i) detecting hateful memes, and (ii) detecting the social entities they target (i. e., Individual, Organization, Community, and Society).
Large Language Models for Document-Level Event-Argument Data Augmentation for Challenging Role Types
A common solution to FSCD modeling is data augmentation.
Align before Attend: Aligning Visual and Textual Features for Multimodal Hateful Content Detection
Evaluation results demonstrate our proposed approach's effectiveness with F1-scores of $69. 7$% and $70. 3$% for the MUTE and MultiOFF datasets.
Chain-of-Thought Embeddings for Stance Detection on Social Media
Chain-of-Thought (COT) prompting has recently been shown to improve performance on stance detection tasks -- alleviating some of these issues.
Text Encoders Lack Knowledge: Leveraging Generative LLMs for Domain-Specific Semantic Textual Similarity
Additionally, we show generative LLMs significantly outperform existing encoder-based STS models when characterizing the semantic similarity between two texts with complex semantic relationships dependent on world knowledge.
Characterizing Information Seeking Events in Health-Related Social Discourse
To the best of our knowledge, this is the first attempt to define event categories for characterizing information-seeking in OUD social discourse.
Theme-driven Keyphrase Extraction to Analyze Social Media Discourse
Lastly, we found that a large language model (ChatGPT) outperforms unsupervised keyphrase extraction models, and we evaluate its efficacy in this task.
MUTE: A Multimodal Dataset for Detecting Hateful Memes
The exponential surge of social media has enabled information propagation at an unprecedented rate.
