Fake News Propagation
Code for ICWSM 2020 paper "Hierarchical Propagation Networks for Fake News Detection: Investigation and Exploitation
" (https://arxiv.org/abs/1903.09196)
Dataset
Hierarchical propagation networks are constructed using the news samples from the FakeNewsNet dataset. To adhere to Twitter's privacy policy, the user information is anonymized and tweet contents are not shared.
The dataset is formatted in the networkx
graph JSON format
and available at data
directory, categorized based on the news source (Politifact/GossipCop) and label.
Each node in the graph contains the random tweet id, exact epoch timestamp, node type, random user id attributes. Additionally, the nodes in the retweet networks(macro networks) have bot score attribute and the nodes in the reply chain network(micro-network) have the sentiment of the tweet content.
For the results mentioned in the paper, randomly down-sampled news ids provided in the data/sample_ids
is used.
To Run:
To use this dataset, un-zip the file nx_network_data.zip
file in data
directory and one can use an example in load_dataset.py
to load the dataset.
To extract features and run the model, install the dependencies in requirements.txt
and use basic_model.py's main function. Function get_classificaton_results_tpnf_by_time
in basic_model
can be used to prune the graphs by time and work on the pruned dataset.
