Text Takes Over: A Study of Modality Bias in Multimodal Intent Detection

EMNLP 2025

The rise of multimodal data, integrating text, audio, and visuals, has created new opportunities for studying multimodal tasks such as intent detection. This work investigates the effectiveness of Large Language Models (LLMs) and non-LLMs, including text-only and multimodal models, in the multimodal

This is not a Disimprovement: Improving Negation Reasoning in Large Language Models via Prompt Engineering

EMNLP 2025

Negation reasoning remains a challenge for large language models (LLMs), often causing incorrect interpretations of negated statements. In this study, we analyze various LLMs for their handling of negation and propose two genres of prompts (*Warning-based* and *Persona-based*), which improve overall

TripCraft: A Benchmark for Spatio-Temporally Fine Grained Travel Planning

ACL 2025long

Recent advancements in probing Large Language Models (LLMs) have explored their latent potential as personalized travel planning agents, though this remains a rather nascent field. Existing benchmarks, such as TravelPlanner and TravelPlanner+, rely on semi-synthetic data as well ignoring several key…

On Zero-Shot Counterspeech Generation by LLMs

COLING 2024main

With the emergence of numerous Large Language Models (LLM), the usage of such models in various Natural Language Processing (NLP) applications is increasing extensively. Counterspeech generation is one such key task where efforts are made to develop generative models by fine-tuning LLMs with hatespe…

LexGLUE: A Benchmark Dataset for Legal Language Understanding in English

ACL 2022long

Laws and their interpretations, legal arguments and agreements are typically expressed in writing, leading to the production of vast corpora of legal text. Their analysis, which is at the center of legal practice, becomes increasingly elaborate as these collections grow in size. Natural language und…
