News

2020/7/16 we have released the codes, and the data for the personachat example is in data_for_personachat (password vzoQ). You can clone the codes and download the data to have a try ^^
2020/7/6 We have already uploaded the Chinese PR-Embedding based on Zhidao (password g3FK) and Weibo (password Yz6H) Zhidao Embedding | Weibo Embedding. Where the Zhidao Embedding has been used in the experiment part of the paper.

Requirements

gcc4.8.5 (or >=4.8.5)
Python3.6
Keras2.1.2 (or >=2.1)
Tensorflow1.12.0 (or >=1.12)
(We run the codes in gcc4.8.5 + Python3.6 + Keras2.1.2 + Tensorflow1.12.0)

Quick Start

1. Prepare the corpus: each line has two columns corresponding to a conversation pair, for example:
   Hi , how are you \t I am fine , Thank you !
2. Train your PR-Embedding:
   sh train.sh $corpus_file $embedding_file
   $corpus_file is coupus file in step 1 and $embedding_file is the output PR-Embedding.
