In addition to hosting user-generated video content, YouTube provides recommendation services, where sets of related and recommended videos are presented users, based on factors such as co-visitation count prior viewing history. This article is specifically concerned with extreme right (ER) portions which contravene hate laws thus illegal in certain countries, by some users. We develop a categorization this content various schema found selection academic literature the ER, then used...
The Syria conflict has been described as the most socially mediated in history, with online social media playing a particularly important role.At same time, ever-changing landscape of leads to difficulties applying analysis approaches taken by other studies political activism.In this paper, we propose an approach motivated Grounded Theory method, which is used within sciences perform situations where key prior assumptions or proposal advance hypothesis may not be possible.We apply method...
As the popularity of content sharing websites has increased, they have become targets for spam, phishing and distribution malware. On YouTube, facility users to post comments can be used by spam campaigns direct unsuspecting malicious third-party websites. In this paper, we demonstrate how such tracked over time using network motif profiling, i.e. tracking counts indicative motifs. By considering all motifs up five nodes, identify discriminating that reveal two distinctly different campaign...
Recent years have seen increased interest in the online presence of extreme right groups. Although originally composed dedicated websites, milieu now spans multiple networks, including popular social media platforms such as Twitter, Facebook and YouTube. Ideally therefore, any contemporary analysis activity requires consideration data sources, rather than being restricted to a single platform. We investigate potential for Twitter act one possible gateway communities within wider network...

As the popularity of content sharing websites such as YouTube and Flickr has increased, they have become targets for spam, phishing distribution malware. On YouTube, facility users to post comments can be used by spam campaigns direct unsuspecting bogus e-commerce websites. In this paper, we demonstrate how tracked over time using network motif profiling, i.e. tracking counts indicative motifs. By considering all motifs up five nodes, identify discriminating that reveal two distinctly...
Abstract We assess the potential of network motif profiles to characterize ego-networks in much same way that a bag-of-words strategy allows text documents be compared vector space framework. This is potentially valuable as generic for comparing nodes terms structure which they are embedded. In this paper, we consider computational challenges and model selection decisions involved profiling. also present three case studies concerning analysis Wikipedia edit networks, YouTube spam campaigns,...
Due to its status as the most popular video sharing platform, YouTube plays an important role in online strategy of extreme right groups, where it is often used host associated content such music and other propaganda. In this paper, we develop a categorization suitable for analysis channels found on YouTube. By combining with NMF-based topic modelling method, categorize originating from links propagated by Twitter accounts. This method also related channels, which are determined using...
CubeSats provide opportunities for science and technology demonstration missions with low-cost solutions short project timescales, in particular, studying gamma-ray bursts (GRBs) the multi-messenger era. A robust operations strategy scientific CubeSat projects is key to optimizing results obtained from experimental instruments. The Educational Irish Research Satellite-1 (EIRSAT-1) a 2U three payloads, including bespoke detector, module (GMOD), developed in-house detection of GRBs. reporting...
Like other social media websites, YouTube is not immune from the attention of spammers. In particular, evidence can be found attempts to attract users malicious third-party websites. As this type spam often associated with orchestrated campaigns, it has a discernible network signature, based on networks derived comments posted by videos. paper, we examine examples different campaigns nature, and use feature selection process identify motifs that are characteristic corresponding campaign...

Gaia is a major European Space Agency (ESA) astrophysics mission designed to map and analyse 109 stars, ultimately generating more than 1 PetaByte of data-products. As data becomes publicly available reaches wider audience, there an increasing need facilitate the further use products without needing download large datasets. The Added Value Interface Platform (GAVIP) address this challenge by providing innovative platform within which scientists can submit deploy code, packaged as "Added...
Topic modeling refers to the task of discovering underlying thematic structure in a text corpus, where output is commonly presented as report top terms appearing each topic. Despite diversity topic algorithms that have been proposed, common challenge successfully applying these techniques selection an appropriate number topics for given corpus. Choosing too few will produce results are overly broad, while choosing many result "over-clustering" corpus into small, highly-similar topics. In...
Many extreme right groups have had an online presence for some time through the use of dedicated websites. This has been accompanied by increased activity in social media platforms recent years, enabling dissemination content to a wider audience. In this paper, we present analysis selection such on Twitter, using network representations based reciprocal follower and interaction relationships, while also analyzing topics found their corresponding tweets. International relationships between...
