面向方面级情感分析的交互式图卷积网络

Interactive Graph Convolutional Network for Aspect-level Sentiment Analysis

  • 摘要: 针对现有的基于图网络的情感分析模型在处理方面短语的内部语义和不同方面之间的情感交互关系时准确度不高等局限性,文章提出一种面向方面级情感分析的交互式图卷积网络模型。首先,利用句子中上下文和方面词之间的句法依存关系,在方面短语内部模块中整合各方面短语之间的内部语义相关性,并将不同方面之间的情感交互关联起来,生成4种类型的邻接矩阵图,实现对方面短语内部语义性和句子中不同方面之间情感交互关系的建模。其次,构建一个方面交互图,用于跨方面关系的建模,以解决不同方面之间的情感交互。最后,在图卷积网络中设置一个全局节点,进一步解决句子中存在多个方面词时精度浮动的问题。在4个公开数据集上的结果表明,该模型在准确率和F1值上均有所提升。

     

    Abstract: A novel interactive graph convolutional network model is proposed to overcome the limitations of existing sentiment analysis models based on graph networks. This model effectively addresses the challenges of handling the internal semantic relations of aspect phrases and the sentiment interactions between different aspects within a sentence. Firstly, by leveraging the syntactic dependencies between context and aspect words, the aspect-inside module integrates the internal semantic correlations among aspect phrases and establishes sentiment interactions between different aspects, resulting in four types of adjacency matrix graphs. This allows for accurate modeling of aspect phrase semantics and the affective interactions between different aspects within a sentence. Secondly, an aspect interaction graph is constructed to capture cross-aspect relations, effectively resolving the issue of sentiment interactions between different aspects. Lastly, the inclusion of a global node in the graph convolutional network further addresses the problem of fluctuating accuracy when multiple aspect words are present in a sentence. The results of experimental on four publicly available datasets demonstrate the effectiveness of the proposed model, showing significant improvements in both accuracy and F1 size.
