Abstract | We propose Adaptive Recursive Neural Network (AdaRNN) for target-dependent Twitter sentiment classification. |

Conclusion | We propose Adaptive Recursive Neural Network (AdaRNN) for the target-dependent Twitter sentiment classification. |

Experiments | For recursive neural models, the dimension of word vector is set to 25, and f = tanh is used as the nonlinearity function. |

Experiments | AdaRNN provides more powerful composition ability, so that it achieves better semantic composition for recursive neural models. |

Introduction | In this paper, we mainly focus on integrating target information with Recursive Neural Network (RNN) to leverage the ability of deep learning models. |

Introduction | The recursive neural models employ the semantic composition functions, which enables them to handle the complex com-positionalities in sentiment analysis. |

Introduction | We employ a novel adaptive multi-compositionality layer in recursive neural network, which is named as AdaRNN (Dong et al., 2014). |

Our Approach | Adaptive Recursive Neural Network is proposed to propagate the sentiments of words to the target node. |

Our Approach | In Section 3.2, we propose Adaptive Recursive Neural Network and use it for target-dependent sentiment analysis. |

Abstract | RZNN is a combination of recursive neural network and recurrent neural network, and in turn integrates their respective capabilities: (1) new information can be used to generate the next hidden state, like recurrent neural networks, so that language model and translation model can be integrated naturally; (2) a tree structure can be built, as recursive neural networks, so as to generate the translation candidates in a bottom up manner. |

Introduction | Recursive neural networks, which have the ability to generate a tree structured output, are applied to natural language parsing (Socher et al., 2011), and they are extended to recursive neural tensor networks to explore the compositional aspect of semantics (Socher et al., 2013). |

Introduction | RZNN is a combination of recursive neural network and recurrent neural network. |

Introduction | In RZNN, new information can be used to generate the next hidden state, like recurrent neural networks, and a tree structure can be built, as recursive neural networks. |

Our Model | RZNN is a combination of recursive neural network and recurrent neural network, which not only integrates the conventional global features as input information for each combination, but also generates the representation of the parent node for the future candidate generation. |

Our Model | In this section, we briefly recall the recurrent neural network and recursive neural network in Section 3.1 and 3.2, and then we elaborate our RZNN in detail in Section 3.3. |

Abstract | This model learns the syntax and semantics of the negator’s argument with a recursive neural network. |

Conclusions | We further make the models to be dependent on the text being modified by negators, through adaptation of a state-of-the-art recursive neural network to incorporate the syntax and semantics of the arguments; we discover this further reduces fitting errors. |

Experimental results | Furthermore, modeling the syntax and semantics with the state-of-the-art recursive neural network (model 7 and 8) can dramatically improve the performance over model 6. |

Introduction | This model learns the syntax and semantics of the negator’s argument with a recursive neural network. |

Related work | The more recent work of (Socher et al., 2012; Socher et al., 2013) proposed models based on recursive neural networks that do not rely on any heuristic rules. |

Semantics-enriched modeling | For the former, we adopt the recursive neural tensor network (RNTN) proposed recently by Socher et al. |

Semantics-enriched modeling | A recursive neural tensor network (RNTN) is a specific form of feed-forward neural network based on syntactic (phrasal-structure) parse tree to conduct compositional sentiment analysis. |

Background | A model that adopts a more general structure provided by an external parse tree is the Recursive Neural Network (RecNN) (Pollack, 1990; Kiichler and Goller, 1996; Socher et al., 2011; Hermann and Blunsom, 2013). |

Experiments | RECNTN is a recursive neural network with a tensor-based feature function, which relies on external structural features given by a parse tree and performs best among the RecNNs. |

Introduction | These range from basic neural bag-of-words or bag-of-n-grams models to the more structured recursive neural networks and to time-delay neural networks based on convolutional operations (Collobert and Weston, 2008; Socher et al., 2011; Kalchbrenner and Blunsom, 2013b). |

Properties of the Sentence Model | Similarly, a recursive neural network is sensitive to word order but has a bias towards the topmost nodes in the tree; shallower trees mitigate this effect to some extent (Socher et al., 2013a). |

Properties of the Sentence Model | The recursive neural network follows the structure of an external parse tree. |

Abstract | Taking inspiration from recent work in sentiment analysis that successfully models the compositional aspect of language, we apply a recursive neural network (RNN) framework to the task of identifying the political position evinced by a sentence. |

Conclusion | In this paper we apply recursive neural networks to political ideology detection, a problem where previous work relies heavily on bag-of-words models and hand-designed lexica. |

Introduction | Building from those insights, we introduce a recursive neural network (RNN) to detect ideological bias on the sentence level. |

Recursive Neural Networks | Recursive neural networks (RNNs) are machine learning models that capture syntactic and semantic composition. |
