WALNUT: Benchmark on Semi-weakly Supervised Learning for NLU

This benchmark provides a publicly accessible framework for advocating and facilitate research on weak supervision for NLU. We expect WALNUT to stimulate further research on methodologies to leverage weak supervision more effectively. The benchmark and code for baselines are available at Website

Graph Neural Networks for Fake News Detection

This repository offers a publicly accessible platform and benchmark for using a series of Graph Neural Network (GNN) based fake news detection models. We welcome contributions of results of existing models and the SOTA results of new models based on our dataset. You can check the benchmark hosted by PaperWithCode for SOTA models and their performances.Benchmark  Github

dEFEND: Explainable Fake News Detection

In recent years, to mitigate the problem of fake news, computational detection of fake news has been studied, producing some promising early results. While important, however, we argue that a critical missing piece of the study be the explainability of such detection, i.e., why a particular piece of news is detected as fake. In this paper, therefore, we study the explainable detection of fake news. We develop a sentence-comment co-attention sub-network to exploit both news contents and user comments to jointly capture explainable top-k check-worthy sentences and user comments for fake news detection. We conduct extensive experiments on real-world datasets and demonstrate that the proposed method not only significantly outperforms several state-of-the-art fake news detection methods. Code and Results.

Unsupervised Fake News Detection

Most existing methods of fake news detection are supervised, which require an extensive amount of time and labor to build a reliably annotated dataset. In search of an alternative, in this paper, we investigate if we could detect fake news in an unsupervised manner. We treat truths of news and users’ credibility as latent random variables, and exploit users’ engagements on social media to identify their opinions towards the authenticity of news. Code

Fake News Detection Data Repository

We released a tool FakeNewsTracker, for collecting, analyzing, and visualizing of fake news and the related dissemination on social media!
The latest dataset paper with detailed analysis on the dataset can be found at FakeNewsNet.
FakeNewsNet is a benchmark data repository fake news detection, which contains information of news content, social context, and spatialtemporal information for studying fake news on social media. Data and APIs are available at Github.

Sarcasm Detection with Emojis

Sarcasm detection on social media is important for users to understand the underlying messages. The majority of existing sarcasm detection algorithms focus on text information; while emotion information expressed such as emojis are ignored. We release a new dataset for our SBP paper on sarcasm detection on social media with emoji information. Data and code are available at Github.

Cross Media Friend & Item Recommendations

Friend and item recommendation on a social media site is an important task, which not only brings conveniences to users but also benefits platform providers. However, recommendation for newly launched social media sites is challenging because they often lack user historical data and encounter data sparsity and cold-start problem. Thus, it is important to exploit auxiliary information to help improve recommendation performances on these sites. We construct a new dataset that ensure that both source and target sites have the following information: user-item interactions, user-user relations, and item features. Raw Data are available at Book  Movie.
