The Bystander Contagion in Enhancing Cyberbully Modelling
Haifa’s project aims to enhance cyberbullying detection by exploring the causative factor of cyberbullying spreading, known as Bystander Contagion. This often-overlooked aspect plays a crucial role in the escalation of cyberbullying behavior. Haifa plans to investigate the detection of cyberbullying through the evaluation of users’ profiles, activities, and social media history, with a specific focus on bystander contagion. The goal is to identify influential cyberbullies or bystanders, enabling the suspension of their accounts to effectively reduce cyberbullying incidents.
In developing the cyberbullying detection model, Haifa will address key points, including the influence and characteristics of bystanders, measurement of bystanders’ contagiousness in cyberbullying diffusion, and identification of the most influential users capable of influencing others. The project will utilize datasets from the Twitter platform, with a focus on Arabic language tweets, acknowledging the unique challenges posed by the complex nature of cyberbullying in Arabic. Haifa’s methodology involves labeling and annotating the data, preprocessing procedures, and applying natural language processing, sentiment analysis, and machine learning with feature extraction for classification purposes.

Multimodal detection of Human Trustworthiness
Under the guidance of Dr. Syaheerah, Li Dongliang ‘s research focuses on multimodal trust detection. Traditional methods typically use statistical analysis to assess trust, but current studies tend to measure trustworthiness through multimodal detection accuracy.
However, accuracy is not the same as trustworthiness. By integrating trust perception in multimodal analysis, new insights can be gained in the field of trust detection. For deception detection, which currently utilizes techniques such as 3D point cloud and image compression, research into trust perception could give AI human-like discrimination. In artificial general intelligence (AGI) research, creators remix film and TV characters and dialogue to achieve high levels of trust without discomforting the viewer.
This study is important because it introduces the concept of trust perception ability. By incorporating trust perception into the analysis, the research can more fully assess people’s trustworthiness and avoid the limitations that come with relying solely on accuracy measures. It provides a new perspective and method for trust detection.

Deepfake Detection
I am Assad H. Thary Al-Ghrairi, currently a PhD student in the School of Computer Sciences at USM. I am also a member of the teaching staff at the College of Science at Al-Nahrain University, Iraq, Baghdad. I am interested in research in computer science, pattern recognition, image processing, artificial intelligence, multimedia, remote sensing, and satellite image classification. Deepfake technology has advanced significantly, posing challenges in distinguishing real from manipulated content, particularly in facial images and videos. Artificial intelligence (AI) plays a crucial role in detecting deepfakes through techniques such as Generative Adversarial Networks (GANs) and Convolutional Neural Networks (CNNs), which analyze facial features and patterns for inconsistencies. Key indicators of deepfake content include unnatural facial movements, artifacts in skin tone, and audio-visual synchronization issues. However, the evolving nature of deepfake creation tools makes detection increasingly difficult, necessitating continuous adaptation of detection methods. Effective AI models require extensive datasets of both real and deepfake content to improve accuracy. As this technology progresses, ongoing research and development in detection strategies are essential to mitigate the risks associated with manipulated media.

Multimodal Trust Modelling at Zero-acquaintance (co-supervision with Assoc. Prof. Dr. Fernando Fernandez)
Christina Luna Jimenez delved into the intricate concept of trustworthiness during her research attachment. The focus was on annotating emotional videos at zero acquaintance in a cross-cultural context, with the intention of translating these annotations into a machine-readable format using machine learning tools.
Christina, alongside researchers from Spain, Malaysia, and Hungary, gathered annotations from diverse cultural backgrounds. However, the final experiments exclusively utilized annotations from Malaysian and Hungarian contributors. The findings revealed that perceived characteristics such as eloquence, attractiveness, and authenticity significantly influenced trustworthiness annotations, displaying high correlation values. Notably, these influences varied across cultures; for instance, kindness played a more crucial role for Hungarians than for Malaysians in determining trustworthiness.
In future endeavors, Christina’s research aims to broaden its scope by incorporating additional cultures, examining both the perspectives represented in the videos and those of the annotators. This expansion seeks to provide a more comprehensive understanding of the cultural nuances influencing trustworthiness perceptions.

Trust Modelling based on Facial Expression using Deep Learning
K. Sarmla investigated trust detection using facial expression towards developing a trust prediction model, for her Masters. In general, behavioral judgement of an individual and decisions on whether to interact or not are highly influenced by trust. Many trust and reputation models were developed in the past but based only on numeric paradigm. The desire to trust is subjective to each individual and is found to be highly affected by one’s facial features. However, do expressions play a role? This serve as the motivation for her to study the effect of human’s facial expressions on trustworthiness of a person by using deep learning based algorithm – Convolutional Neural Network (CNN).
