    On the Detection of Images Containing Child-Pornographic Material by Emilios Yiallourou, Rafaella Demetriou and Andreas Lanitis. The vast increase in the use of social networks and other internet-based communication tools contributed to the escalation of the problem of exchanging child pornographic material over the internet. The problem of dissemination of child pornographic material could be addressed using dedicated image detection algorithms capable of rating the inappropriateness level of images exchanged through computer networks so that images with inappropriate content involving children are blocked.However, the complexity of the image detection task coupled with the nonexistence of suitable datasets, inhibit the development of efficient algorithms that can be used for detecting offensive images containing children.  To deal with the problem, we propose a methodological approach that can be used for supporting the development of child pornography detectors through the generation of synthetic datasets and through the decomposition of the task into a set of simpler tasks for which training data is available.  Preliminary results show the promise of the proposed approach. More information can be found here”:

The aim is to present and make known the actions of the ENCASE programme as well as to provide an opportunity for information sharing and at the same time create opportunities for partnerships and synergies between those involved in safety issues on the Internet. The concept of the effective and creative use of the Internet with security, responsibility and creativity is one of the primary goals of the Republic of Cyprus.The optimal exploitation of the potentials provided by the Information and Communications Technologies (ICT) in order to promote innovation, financial growth and progress is promoted by the Digital Agenda presented in the European Commission in May 19th, 2010.The Republic of Cyprus is following the European and international standards in this respect, with the recent approval of the National Strategy on Cybersecurity for the Republic of Cyprus by the Ministry Council (Ref. Decision 74.721, Date of Decision 14/02/13, Date of Assignment 27 / 3/13) under the coordination of the Office of the Commissioner of Electronic Communications and Postal Services (OCECPR). In this context, the Ministry of Education and Culture has accepted the invitation to coordinate the Working Group on the Safe Internet for children, teachers and parents.The national strategy proposal aims to provide information and education on digital security issues, which will be addressed to children, teachers and parents in order to become critical and responsible users of digital technologies and develop culture of safe use of the possibilities of digital technologies.For more information, please visit the link:”

    “It is our pleasure to announce that on Monday, April 10th, Associate Prof. Nick Bassiliades of the Aristotle University will be visiting CUT to present a lecture on Web Information Extraction, Semantic Entity Identification and Linking.The talk will cover some aspects of Web Information Extraction so that extracted entities can be uniquely identified by semantic similarity search in Web knowledge bases (a.k.a. Linked Open Data) and linked to their similar entities in these datasets.
    Technologies that will be discussed are Web Data Extraction terms and tools, giving emphasis to the DEiXTo tool, and Semantic Web related languages, such as RDF, SPARQL. The dataset that will be described is the DBpedia LOD dataset.All the above is going to be explained through a concrete use case which extracts data about University rankings from the web sites of several well-known ranking lists, then uniquely identify Universities by linking them to the corresponding DBpedia entity, and finally, merges individual ranking lists into a single dataset to compare different ranking lists statistically. The use case is supported by a Prolog application that will be briefly described as well.

    All Electrical Engineering, Computer Science and Engineering, Multimedia, Communications and Internet Studies, and Geoinformatics students. Also anyone else with an interest in information technology, software and computer engineering.Speakers: Associate Prof. Nick Bassiliades, Aristotle University of Thessaloniki.When: 10th of April 2017 at 10:00am to 13:00pm.

    “Mean Birds: Detecting Aggression and Bullying on Twitter by Despoina Chatzakou, Nicolas Kourtellis, Jeremy Blackburn, Emiliano De Cristofaro, Gianluca Stringhini, and Athina Vakali.Over the past few years, bullying and aggression of Internet users have grown on social media platforms, prompting serious consequences to victims of all ages. Recent cyberbully-ing incidents have even led to teenage suicides, prompted by prolonged and/or coordinated digital harassment. Although this issue affects as many as half of young social media users, tools and technologies for understanding and mitigating it are scarce and mostly ineffective. In this paper, we present a principled and scalable approach to detect bullying and aggressive behavior on Twitter. We propose a robust methodology for extracting text, user, and network-based attributes from a corpus of 1.6M tweets posted over 3 months. We study the properties of cyberbullies and aggressors and what features distinguish them from regular users, alongside crowdsourced labeling provided by human annotators. Finally, we use machine learning classification algorithms to detect users exhibiting bullying and aggressive behavior, achieving over 90% AUCROC. More information can be found here”.

    “In February 24, 2017 Measuring #GamerGate: A Tale of Hate, Sexism, and Bullying by Emiliano De Cristofaro, Despoina Chatzakou, Jeremy Bluckburn, Nicolas Kourtellis, Athina Vakali, Gianluca Stringhini has been accepted for presentation at Cybersafety Workshop 2017. Over the past few years, online aggression and abusive behaviors have occurred in many different forms and on a variety of platforms. In extreme cases, these incidents have evolved into hate, discrimination, and bullying, and even materialized into real-world threats and attacks against individuals or groups. In this paper, we study the Gamergate controversy. 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 focus on Twitter, presenting a measurement study of a dataset of 340k unique users and 1.6M tweets to study the properties of these users, the content they post, and how they differ from random Twitter users. We find that users involved in this “Twitter war” tend to have more friends and followers, are generally more engaged and post tweets with negative sentiment, less joy, and more hate than random users. We also perform preliminary measurements on how the Twitter suspension mechanism deals with such abusive behaviors. While we focus on Gamergate, our methodology to collect and analyze tweets related to aggressive and bullying activities is of independent interest. More information can be found here:”

This work was completed for the purposes of H2020 project ENCASE, that aims to protect youngsters in Online Social Networks and the Web in general. The current publication proposes a framework to detect potentially malicious users in Twitter and defines the concept of “social bridges”, meaning the influential users that are utilized by the malicious ones to help penetrate the large component of an OSN. A topology based classification model was introduced to allow for early detection of any dangerous new connection of underage Twitter users. In addition this work is motivated by the strong need to safeguard youngsters OSNs experience such that they can be empowered and aware. The topology of a graph is studied towards detecting the so called social bridges, i.e. the major supporters of malicious users, who have links and ties to both honest and malicious user communities. A graph-topology based classification scheme is proposed to detect such bridge linkages which are suspicious for threatening youngsters networking. More information can be found here:”
