This paper presents an overview of the Perspective-aware Answer Summarization (PerAnsSumm) Shared Task on summarizing healthcare answers in Community Question Answering forums hosted at the CL4Health Workshop at NAACL 2025. In this shared task, we approach healthcare answer summarization with two subtasks: (a) perspective span identification and classification and (b) perspective-based answer summarization (summaries focused on one of the perspective classes). Wedefine a benchmarking setup for comprehensive evaluation of predicted spans and generated summaries. We encouraged participants to explore novel solutions to the proposed problem and received high interest in the task with 23 participating teams and 155 submissions. This paper describes the task objectives, the dataset, the evaluation metrics and our findings. We share the results of the novel approaches adopted by task participants, especially emphasizing the applicability of Large Language Models in this perspective-based answer summarization task.

Memes have evolved as a prevalent medium for diverse communication, ranging from humour to propaganda. With the rising popularity of image-focused content, there is a growing need to explore its potential harm from different aspects. Previous studies have analyzed memes in closed settings - detecting harm, applying semantic labels, and offering natural language explanations. To extend this research, we introduce MemeMQA, a multimodal question-answering framework aiming to solicit accurate responses to structured questions while providing coherent explanations. We curate MemeMQACorpus, a new dataset featuring 1,880 questions related to 1,122 memes with corresponding answer-explanation pairs. We further propose ARSENAL, a novel two-stage multimodal framework that leverages the reasoning capabilities of LLMs to address MemeMQA. We benchmark MemeMQA using competitive baselines and demonstrate its superiority - ~18% enhanced answer prediction accuracy and distinct text generation lead across various metrics measuring lexical and semantic alignment over the best baseline. We analyze ARSENAL’s robustness through diversification of question-set, confounder-based evaluation regarding MemeMQA’s generalizability, and modality-specific assessment, enhancing our understanding of meme interpretation in the multimodal communication landscape.
