Profile
Biography
My research is focused on natural language understanding, currently, I have three research threads: 1: Applying linguistic knowledge bases to fundamental NLP models, including LLMs. 2: NLP/LLM applications in healthcare, and digital wellbeing. 3: Neuro-Cognitive NLP and its application in affective analysis/misinformation detection based on text and multimodality data.

Research and professional activities
Research interests
Developing novel Natural Language Processing and Explainable AI for modelling healthcare data
This research aims to develop a series of improvement works for NLP and XAI in clinical data and other health-related data that will provide: 1. Adapt Responsible Research & Innovation (RRI) methods to start the interdisciplinary clinical data science and NLP works in Essex. 2. Prototype a person-centered supervised model training process to refine definitions and expose and explore tacit and latent knowledge in psychotherapy assessment. 3. Identify the key factors contributing to performance and trust in the model pipeline (data, processing, deployment) by examining domain expert requirements for the qualities of an engaging, interactive feedback interface and eliciting broader concerns about its acceptability. 4. Assess whether patient and practitioner knowledge base in developing a digital mental health decision support tool increases performance and trust in it.
Leveraging Lexical Semantics in Affective Analysis (and other NLP applications)
This study aims to investigate novel models to incorporate features of lexical items and ontologies in English from external resources into neural NLP frameworks. This allows the models to take the combined effects of bi-directional feeling between the professional knowledge and the text to infer human affective understanding and to the wider Natural language understanding.
Large Language Models for Games
Autonomous Communication, Learning, and Interaction in Game NPCs: Immersive Gameplay forge deeper connections with realistic NPCs, transforming storytelling and user engagement within the digital gaming landscape.
Misinformation and affective analysis
In 2022, misinformation ranked as the second highest online threat in the UK, with 22% encountering it within a month (Ofcom, 2022). This issue, intricately tied to emotion, spans platforms like social media and fields such as politics. People heavily influenced by emotions are more prone to fake news, and when guided by emotions, their susceptibility increases, a stark contrast to logic-driven individuals. The emotional pull plays a pivotal role in misinformation vulnerability, potentially disrupting social media communities. Moreover, misinformation breeds distrust even towards credible news. Further complicating matters, figurative language in misinformation can mislead, especially when cultural idioms are taken out of context. It's vital to distinguish between misinformation and satire, both of which can employ similar rhetorical tools, risking context loss in the digital realm. Counterstrategies must understand the emotional, cognitive, and cultural underpinnings that shape misinformation beliefs (Carmen Sanchez, 2021). Initial fake news detection relied on linguistic cues. Several research endeavours have adopted diverse detection techniques, from focusing on sentiment indicators in content to leveraging advanced neural networks for tweet analysis (Kashyap Popat, 2016). Contemporary Natural Language Processing (NLP) leans towards holistic approaches. Yet, few tackle misinformation from an emotional angle. Our project fills this gap, focusing on emotion, metaphor, and irony in misinformation detection. This effort holds potential for significant policy implications, highlighting the importance of emotion-centric analysis in battling misinformation.
