AI RESEARCH BREAKTHROUGH
User Opinion-Focused Abstractive Summarization Using Explainable Artificial Intelligence
Authors: Hyunho Lee, Younghoon Lee
Recent methodologies have achieved good performance in objectively summarizing important information from fact-based datasets. However, opinion-based documents require a thorough analysis of sentiment and understanding of the writer's intention. This study proposes a novel text summarization model specifically designed for opinion-based documents, identifying sentiment distribution and training the model to focus on major opinions while randomly masking minor ones. Experimental results show superior performance in capturing and highlighting main opinions in generated abstractive summaries.

The Challenge of Opinion Summarization
Traditional abstractive summarization models, while effective for fact-based documents like news articles, often fall short when processing opinion-rich content such as customer reviews. These models typically summarize objectively, failing to grasp the nuanced sentiment and underlying intent of the author. This research addresses this critical gap by introducing a novel abstractive summarization framework designed specifically for opinion-based texts. By leveraging Explainable AI (XAI) principles, our model accurately identifies and prioritizes the core sentiments, delivering summaries that genuinely reflect the user's intended message, thereby transforming raw feedback into actionable intelligence for businesses.

Generate Sentiment-Aligned Summary
Our methodology enhances existing abstractive summarization models with a unique XAI-driven approach. First, a classification head and SHAP explainer identify the sentiment distribution of the input text. This allows for the precise extraction of "major" opinions (core sentiment) and "minor" opinions (secondary or less relevant sentiments). During training, minor opinions are subjected to incremental random masking, ensuring the model learns to prioritize and emphasize the major opinions within the encoder-decoder multi-attention mechanism. This targeted masking, coupled with a sentiment classification loss function, ensures that the generated summaries accurately reflect the author's intended message.
