The main directory contains the directories of Weibo dataset and two Twitter datasets: twitter15 and twitter16. In each directory, there are:

• twitter15.train, twitter15.dev, and twitter15.test file: This files provide traing, development and test samples in a format like: 'source tweet ID \t source tweet content \t label'

• twitter15_graph.txt file: This file provides the source posts content of the trees in a format like: 'source tweet ID \t userID1:weight1 userID2:weight2 ...'

These dastasets are preprocessed according to our requirement and original datasets can be available at https://www.dropbox.com/s/7ewzdrbelpmrnxu/rumdetect2017.zip?dl=0 (Twitter) and http://alt.qcri.org/~wgao/data/rumdect.zip (Weibo).

If you want to preprocess the dataset by youself, you can use the word2vec used in our work. The pretrained word2vec can be available at https://drive.google.com/drive/folders/1IMOJCyolpYtoflEqQsj3jn5BYnaRhsiY?usp=sharing.

1. create an empty directory: checkpoint/
2. run script run.py
