Prof. Alon Halevy, University of Washington and Director of AI at Meta (previously Facebook)
Abstract: Obtaining Answers from Social Media Data.
Content posted on social media is a rich set of data from which we would like to answer a broad set of questions. As one important example, keeping users safe on social networks requires that we identify content that contains misinformation or hateful speech and remove it. Similarly, users may be interested in getting additional value from their network such as finding friends who recently traveled to a particular destination or finding out which movies their friends are discussing. The typical machine learning approach in which we develop a model for every question we want to ask works well for questions we ask constantly (e.g., find hate speech), but not for ad-hoc questions that occur infrequently. In this talk I will advocate for an approach that combines the benefits of machine learning and database-style query answering. I will illustrate this approach through the idea of Neural Databases, a new kind of database system that leverages the strength of pre-trained language models to answer database queries over text and other modalities.

Prof. Tihana Galinac Grbac, Juraj Dobrila University of Pula, Croatia
Abstract: Software Engineering Meets Software Defined Networks.
Software has progressively entered every aspect of human life. The number of devices and platforms surrounding and supporting humans in every day activities is continuously growing. These devices and platforms are software based and interconnected over Internet in the new 5G network, which is virtual, software defined and reconfigurable. In such new circumstances, the classical software engineering theories must be revisited and extended, new areas of software engineering research emerge at high pace, the new rules and principles and open and clear standards of software and network design are needed more than ever, while at the same time new questions and problems continuously arise. These include, to mention just a few, the integration and management problems of heterogenous technologies required to achieve the full potential of software defined networks and autonomos managed traffic packets within future networked systems, the new levels of authorities for network and software providers, current software development trends that are driven by working solutions and on the fly improvements, harmonization of various goals while delivering reliable, safe, user friendly and sustainable solutions. In this talk we provide basic understanding of current trends in engineering software systems of future networks, revisit the software design principles which are of particular importance from software defined network perspective, and discuss challenges that curent software and system engineering technologies must address in order to enable sustainable future evolution. |

Prof. Annalisa Appice, University of Bari Aldo Moro, Italy.
Abstract: AI meets Cybersecurity
With the growing processing power of computing systems and the increasing availability of massive datasets, along with novel concepts and architectures for deep learning, AI algorithms have led to major breakthroughs in many different areas ioncluding cybersecurity. Nowadays AI has become one of the key enablers to studying and addressing cybersecurity-relevant problems at large in several application domains such as for intrusion detetction, malware detection and spam detection. However, it is important to consider that AI can be used also by attackers to continually improve their techniques and refine their offensive capabilities. Studying the effectiveness of AI is thus critical to ensure modern cybersecurity equipped to face the emerging threats allowed by malicious uses of AI. In this talk I will showcase several examples of recent progress in applying AI into cyber-threat detection problems and will provide a glimpse into exciting future directions that promise to have a profound impact on cybersecurity.

Prof Farid Meziane, University of Derby, UK
Abstract: Ultrasound reports standardisation using rhetorical structure theory and domain ontology.
Ultrasound reporting plays an important role in diagnosis as images produced during an ultrasound examination do not give the whole view of the medical conditions. However, in practice there are many issues that are inherent to ultrasound reporting and the most important was identified to be the lack of standardisation when producing these reports. There is a resistance to change from some radiologists preferring the free writing style, making any attempt to computerise the processing of these reports difficult. This research explores the possibility of using Rhetorical Structure Theory (RST) together with a domain ontology to transform free-form ultrasound reports into a structured form. It discusses a new approach in segmenting and identifying rhetorical relations that are more applicable to ultrasound reports from classical RST relations. The approach was evaluated on a sample ultrasound reports where the system’s parsing was compared to the manual parsing performed by experts. The results show that discourse parsing using RST in ultrasound reports can be performed effectively using the support of a domain ontology. The results also demonstrate that the transformation of free-form ultrasound reports into a structured form can be performed with the support of RST relations identified and the domain ontology.

Prof Elisabeth Lex, Graz University of Technology, AUSTRIA
Abstract: Psychology-informed recommender systems.
Personalized recommender systems are essential tools to facilitate human decision making. Many contemporary recommender systems use advanced machine learning techniques to model and predict user preferences from behavioral data. While such systems can provide helpful recommendations, their algorithms' design does not incorporate the underlying psychological mechanisms that shape user preferences and behavior. In this keynote, we will discuss recent work in psychology-informed recommender systems, i.e., recommender systems that consider extrinsic and intrinsic human factors in their algorithmic design. We show how such systems can improve the recommendation process in a user-centric fashion.

Abstract: Automating disinformation detection: the challenges from a social science perspective.
The mitigation of online disinformation is an urgent and challenging problem. However, it is also beset with conceptual, practical, and regulatory difficulties.
This talk will review these challenges from a social science perspective and contextualise them in terms of the EU’s wide-ranging response to the problem. It will also
present the concept behind an EU-funded project which seeks to marry technical and social science
perspectives as well as presenting original research which addresses the challenge of generating large-scale training data for the development of automated disinformation detection.
