基于多任务学习的古诗和对联自动生成

实现古诗和对联的自动生成是极具挑战性的任务。该文提出了一种新颖的多任务学习模型用于古诗和对联的自动生成。模型采用编码-解码结构并融入注意力机制,编码部分由两个BiLSTM组成,一个BiLSTM用于关键词输入,另一个BiLSTM用于古诗和对联输入;解码部分由两个LSTM组成,一个LSTM用于古诗的解码输出,另一个LSTM用于对联的解码输出。在中国的传统文学中,古诗和对联具有很多的相似特征,多任务学习模型通过编码器参数共享,解码器参数不共享,让模型底层编码部分兼容古诗和对联特征,解码部分保留各自特征,增强模型泛化能力,表现效果大大优于单任务模型。同时,该文在模型中创新性地引入关键词信息,让生成的古诗及对联表达内容与用户意图一致。最后,该文采用自动评估和人工评估两种方式验证了方法的有效性。

Chinese Classical Poetry and Couplet Generation Based on Multi-task Learning

This paper proposes a novel multi-task learning model for the automatic generation of classical poetry and couplet, which uses an encoder-decoder structure and the attention mechanism. The encoder consists of two BiLSTMs, one for keyword input, the other for classical poetry and couplet input. The decoder consists of two LSTMs, one for classical poetry output, the other for couplet output. In the multi-task learning model, the encoder parameters are shared and the decoder parameters are not shared. The encoder of model can learn the common features of classical poetry and couplet, the decoder of classical model can learn the unique features of classical poetry and couplet. So, the generalization ability of the model will be enhanced, and the performance will be much better than the single task model. At the same time, this paper innovatively introduces keyword information in the model, so that the generated classical poetry and couplet are consistent with the user's intention. At the end of this paper, automa-tic evaluation and manual evaluation are used to verify the effectiveness of the method.
