Close. An inherent limitation of word representations is their indifference to word order and their inability to represent idiomatic phrases. The bottom and top of the box are always the first and third quartiles, the band inside the box is the median, the whiskers represents the minimum and maximum values, and the dots are outliers.

While the social network promotes a hard-line view in support of free speech, critics often refer to it as “Twitter for racists.” Researchers who have studied Gab found that it acts as a meeting place and an echo chamber for white, male extremists, and the company’s app has already been banned from the Apple and Google app stores. between online news videos and user comments. Senator warns YouTube algorithm may be open to manipulation.

Started in August 2014 in the online gaming world, it quickly spread across various social networking platforms, ultimately leading to many incidents of cyberbullying and cyberaggression. We also depict, in Figur, values, aggregating for channel type and source, and considering. The need for these kinds of platforms is a recent development. we do, Proceedings of the 2016 CHI Conference on, International Conference on Machine Learn-, Advances in Neural Information Processing Systems, Proceedings of the ACL 2012 System Demonstrations, La méthode en lexicologie: domaine français, Proceedings of the Conference on Neural Information Processing Systems (NIPS), Proceedings of the ACM 2011 Conference on, Proceedings of the LREC 2010 Workshop on New Challenges, Proceedings of the 20th Nordic Conference of Computational Linguistics, Text and corpus analysis: Computer-assisted studies of.
To start growing your network, and add Lil Miss Florida TH Hoffenden as a connection, you must have a Channel Pages account. Future research should investigate how specific interventions, such as online counter-narratives to battle propaganda, may be effectively implemented to mitigate the spread of far-right extremism in the United States. In this paper, we first introduce a transfer learning approach for hate speech detection based on an existing pre-trained language model called BERT (Bidirectional Encoder Representations from Transformers) and evaluate the proposed model on two publicly available datasets that have been annotated for racism, sexism, hate or offensive content on Twitter. Although not capturing a dierence of, bias against immigrants and LGBT people, we were able to capture, a negative bias against the Muslim community. Next, we introduce a bias alleviation mechanism to mitigate the effect of bias in training set during the fine-tuning of our pre-trained BERT-based model for hate speech detection.
In this article, we quantitatively analyze how the term "fake news" is being shaped in news media in recent years. They add that most commentators and comment read-, ers “agree that allowing anonymity in comment sections allows, participants to express ideas they might be afraid to express other-, wise”, while nearly half of them believe that “allo.
The proposed strategy relies on combining linguistic features to improve the classifier’s performance. Neural word embedding as implicit matrix, Paul Lewis. by pointing out some possible future works. Request permissions from firstname.lastname@example.org. Please login, or create one to continue. As a reference, in order to compare results provided by DMTK, two free of charge machine learning algorithms Gensim and GloVe were scrutinized. millie, quot, owen, korean, gangs, ricegum, discrimination, u, speaker, feminists, jay.
The words that compose, each class and attribute in our tests are shown in Table 3. 2018. Adapting word2vec to named entity recogni-. At the same time, far-right groups have also taken an interest in genetic testing, using them to attack minorities and prove their genetic "purity. " Regarding the top ranked topics for the right-wing comments, it is possible to recognize many words probably related to bio-, As expected, the words in the top ranked topics of the baseline, channels seem to cover a wider range of subjects. The use of our multi-layered approach mitigates, this problem, but, in future work, we plan to improve our analyses, in this regard. Like it or not, the far right is heading for Germany’s Bun-, Manoel Horta Ribeiro, Pedro H Calais, Yuri A Santos, Virgilio AF Almeida, and, Saiph Savage and Andrés Monroy-Hernández. In particular, on 4chan's politically incorrect board (/pol/), content from genetic testing conversations involves several alt-right personalities and openly anti-semitic rhetoric, often conveyed through memes. Gab is not the first company to try to find success as a right-wing niche. vectors: one for its captions and another one for its comments. In, Workshop on Natural Language Processing for Social Media, Scharolta Katharina Sienčnik. Semantics derived. In order to build a baseline set of channels to compare the results, of the analyses performed in these right-wing channels with a, information (captions and comments) from videos posted in the, ten most popular channels (in terms of number of subscribers in, November 7 2017) of the category "news and politics" according to, dataset, the content of these channels needed to be mainly in English, language and non hard-coded captions needed to be available for the, most part of the videos.
There has been relatively little research on modeling and safeguarding these platforms. This similarity also varies among channels. The incorporation of time, analysis may also improve our LDA results, since it would be pos-, sible to create the notion of conversation sessions and to split the, large documents that aggregate all videos’ comments into smaller, This work was partially supported by CNPq, CAPES, FAPEMIG and, Ashar and Robert Faris, from the Berkman Klein Center for Internet, & Society at Harvard University, for their insightful discussions.
In response to the tougher standard, which he called a threat to the Rebel channel, Levant launched a crowdfunded effort to build “a conservative alternative” to YouTube.

Growing criticism over the role these companies have played in spreading inflammatory content — magnified by Russia’s use of tech platforms to spread misinformation, particularly in the 2016 U.S. presidential election — has slowly pushed tech giants to take a more hands-on role in policing their networks. Tom Whyman. 2016.

The Guardian, http://bit.ly/2EtlimT. but also show contextual changes around this expression after the United States presidential election of 2016. We might con-, clude, then, that hateful vocabulary and violent content seems to be, more accentuated in right-wing channels than in our set of baseline, channels, and also that a discriminatory bias against Muslims is, RQ-2: are, in general, commentators more, less or equally exacer-.
More precisely, the method combines. On the other hand, comments contain predominantly, there is no signicant dierence for right-wing channels, for the, baseline channels there is a considerable dierence between cap-, tions and comments: median of 3.5% vs. 6.8%, respectively, thus, Figure 1: Normalized percentage of words in each semantic eld represented by an Empath category.

Why do we ask for the “Manage Account” permission?
To address these needs, in this study we introduce a novel transfer learning approach based on an existing pre-trained language model called BERT (Bidirectional Encoder Representations from Transformers). As our key contribution, we develop a systematic approach to detect malicious users on commenting platforms.
tioned in Section 2.2, lemmatization was applied by employing the, lemmatization method. captions with the ones addressed in the comments. We collect 1.3M comments posted over 27 months on the two platforms, using a set of 280 keywords related to genetic testing. The lack of a sufficient amount of labelled hate speech data, along with the existing biases, has been the main issue in this domain of research. We study the perception and the conceptualization of this term in the traditional media using eight years of data collected from news outlets based in 20 countries. According to Adams’ latest video, Jones’ move to the Real.Video platform has caused a surge in new users and the creation of over 350 new channels on the site in the last day, an uptick from the “dozens” that he noted in a video three weeks ago. Our initial research questions are the following: is the presence of hateful vocabulary, violent content and, discriminatory biases more, less or equally accentuated in, are, in general, commentators more, less or equally exac-, erbated than video hosts in an eort to express hate and, One of the side contributions of this paper is the proposal of a, three-layered method that can be used to evaluate the presence of, hate speech and discriminatory bias not only on YouTube videos, and comments, but in any kind of text instead. 2017. virtual services that host a high variety of right-wing voices [, but also to react to them through comments, it is interesting to, observe how these comments are related to the content of the videos, published in the platform. Overall, we paint a comprehensive picture of the evolution of the Manosphere on the Web, showing the links between its different communities over the years. Its core idea is to measure the strength of associa-, needed to match (a) items that correspond to the target concepts. The quality of these representations is measured in a word similarity task, and the results are compared to the previously best performing techniques based on different types of neural networks. Regarding the captions, we observe no signicant correlation for, the right-wing channels, and a signicant positive correlation for, These results imply that baseline channels with higher fraction of, words related to hate and negative emotions also have a higher. In this article, we present a cross-national comparative analysis of which online news users in practice engage with the participatory potential for sharing and commenting on news afforded by interactive features in news websites and social media technologies across a strategic sample of six different countries. Adams is the founder of Real.Video, a platform he launched in March after he, too, was kicked off YouTube for what it called violations of community guidelines.
