Context-Aware Deep Markov Random Fields for Fake News Detection

نویسندگان

چکیده

Fake news is a serious problem, which has received considerable attention from both industry and academic communities. Over the past years, many fake detection approaches have been introduced, most of existing methods rely on either content or social context dissemination process media platforms. In this work, we propose generic model that able to take into account for identification news. Specifically, explore different aspects by using shallow deep representations. The representations are produced with word2vec doc2vec models while generated via transformer-based models. These jointly separately address four individual tasks, namely bias detection, clickbait sentiment analysis, toxicity detection. addition, make use graph convolutional neural networks mean-field layers in order exploit underlying structural information articles. That way, inherent correlation between articles leveraging their information. Experiments widely-used benchmark datasets indicate effectiveness proposed method.

Exploiting Tri-Relationship for Fake News Detection

Social media for news consumption is becoming popular nowadays. The low cost, easy access and rapid information dissemination of social media bring benefits for people to seek out news timely. However, it also causes the widespread of fake news, i.e., low-quality news pieces that are intentionally fabricated. The fake news brings about several negative effects on individual consumers, news ecos...

Automatic Detection of Fake News

The proliferation of misleading information in everyday access media outlets such as social media feeds, news blogs, and online newspapers have made it challenging to identify trustworthy news sources, thus increasing the need for computational tools able to provide insights into the reliability of online content. In this paper, we focus on the automatic identification of fake content in online...

Stance Detection for Fake News Identification

The latest election cycle generated sobering examples of the threat that fake news poses to democracy. Primarily disseminated by hyper-partisan media outlets, fake news proved capable of becoming viral sensations that can dominate social media and influence elections. To address this problem, we begin with stance detection, which is a first step towards identifying fake news. The goal of this p...

Defect Detection Using Hidden Markov Random Fields

We derive an approximate maximum a posteriori (MAP) method for detecting NDE defect signals using hidden Markov random fields (HMRFs). In the proposed HMRF framework, a set of spatially distributed NDE measurements is assumed to form a noisy realization of an underlying random field that has a simple structure with Markovian dependence. Here, the random field describes the defect signals to be ...

Markov Random Fields and Conditional Random Fields

Markov chains provided us with a way to model 1D objects such as contours probabilistically, in a way that led to nice, tractable computations. We now consider 2D Markov models. These are more powerful, but not as easy to compute with. In addition we will consider two additional issues. First, we will consider adding observations to our models. These observations are conditioned on the value of...
