Sentence function is a significant factor to achieve the purpose of the speaker. In this paper, we present a novel model to generate informative responses with controlled sentence function. Given a user post and a sentence function label, our model is to generate a response that is not only coherent with the specified function category, but also informative in content.

This project is a tensorflow implementation of our work.

• Python 2.7
• Numpy
• Tensorflow 1.3.0

• Dataset

  Our dataset contains single-turn post-response pairs with corresponding sentence function labels. The sentence function labels of responses have been automatically annotated by a self-attentive classifier.

  Please download the Chinese Dialogue Dataset with Sentence Function Labels to data directory.

• Train

  python main.py

• Test

  python main.py --is_train=False --inference_path='xxx' --inference_version='yyy'

  You can test the model using this command. You may set the directory of test set with inference_path and the checkpoint to be used with inference_version. The generation result will be output to the 'xxx.out' file.

You can change the model parameters using:

--symbols xxx				size of full vocabulary
--topic_symbols xxx			size of topic vocabulary
--full_kl_step xxx			parameter of kl annealing
--units xxx 				size of hidden units
--embed_units xxx			dimension of word embedding
--batch_size xxx 			batch size in training process
--per_checkpoint xxx 			steps to save and evaluate the model
--data_dir xxx				data directory
--train_dir xxx				training directory
