Sentiment analysis based on rhetorical structure theory:Learning deep neural networks from discourse trees

作者:

Highlights:

• Improves sentiment analysis with discourse trees from rhetoric structure theory.

• Extracts salient passages based on the position and relation in the discourse tree.

• Develops a tensor-based tree-structured neural network.

• Tensor structure distinguishes hierarchy and relation types.

• Overfitting is reduced by a tree-based algorithms for data augmentation.
