Summary

With the explosive growth of user-generated content on platforms such as Twitter/X, Reddit, YouTube, Facebook, and TikTok, social media has emerged as a rich and dynamic source of public opinion, behavioral signals, and emotional expression. Sentiment analysis — the computational study of people's opinions, sentiments, emotions, and attitudes — has become a critical tool for extracting actionable insights from this vast stream of text data.


Historically, lexicon-based sentiment analysis approaches, which rely on curated dictionaries and sentiment scoring algorithms, have been effective for many constrained or interpretable settings. However, these methods often struggle with informal language, sarcasm, and domain adaptation. In recent years, Large Language Models (LLMs) such as BERT, RoBERTa, GPT, and LLaMA have revolutionized sentiment analysis by leveraging deep contextual embeddings and transfer learning, significantly outperforming traditional approaches on benchmark tasks.


Despite the promise of these methods, several open challenges persist. These include handling multimodal content (e.g., text with images or videos), ensuring fairness and transparency, interpreting black-box model outputs, mitigating bias, and managing evolving slang and linguistic diversity across platforms and cultures.


This special issue invites original research articles, surveys, and case studies that focus on innovations, evaluations, comparisons, and applications of sentiment analysis techniques for social media data — spanning both lexicon-based and large language model-based paradigms.

    Abstract Multimodal Aspect-Based Sentiment Analysis (MABSA) aims to detect sentiment polarity toward specific aspects by leveraging both textual and visual inputs. However, existing models suffer from weak aspect-image alignment, modality imbalance dominated by textual signals, and limited reasoning for implicit or ambiguous sentiments requiring external knowledge. To address these issues, we propose a unified framework named Gated-Linear Aspect-Aware Multimodal Sentiment Network (GLAMSNet). First of all, an input encoding module is employed to construct modality-specific and aspect-aware representations. Subsequently, we introduce an image–aspect correlation matching module to provide hierarchical supervision for visual-textual alignment. Building upon these components, More >
