AI总结:

SentiFuse通过多模型融合框架提升情感提取的鲁棒性和准确性,特征级融合在F1分数上取得显著提升。

摘要:

情感分析模型具有互补的优势,但现有方法缺乏有效的统一整合框架。我们提出了SentiFuse,一种灵活且模型无关的框架,通过标准化层和多种融合策略整合异构情感模型。我们的方法支持决策级融合、特征级融合和自适应融合,使不同模型能够系统性地结合。我们在三个大规模社交媒体数据集上进行了实验:Crowdflower、GoEmotions和Sentiment140。这些实验表明,SentiFuse在一致性和稳定性上均优于单独模型和简单集成。特征级融合实现了最强的整体效果,相对于最佳单独模型和简单平均,F1分数提高了高达4%。自适应融合在处理否定、混合情绪和复杂情感表达等挑战性案例时增强了鲁棒性。这些结果表明,系统地利用模型互补性能够提高不同数据集和文本类型上的情感分析准确性和可靠性。

英文摘要:

Sentiment analysis models exhibit complementary strengths, yet existing approaches lack a unified framework for effective integration. We present SentiFuse, a flexible and model-agnostic framework that integrates heterogeneous sentiment models through a standardization layer and multiple fusion strategies. Our approach supports decision-level fusion, feature-level fusion, and adaptive fusion, enabling systematic combination of diverse models. We conduct experiments on three large-scale social-media datasets: Crowdflower, GoEmotions, and Sentiment140. These experiments show that SentiFuse consistently outperforms individual models and naive ensembles. Feature-level fusion achieves the strongest overall effectiveness, yielding up to 4\% absolute improvement in F1 score over the best individual model and simple averaging, while adaptive fusion enhances robustness on challenging cases such as negation, mixed emotions, and complex sentiment expressions. These results demonstrate that systematically leveraging model complementarity yields more accurate and reliable sentiment analysis across diverse datasets and text types.
