Profile
Biography
My research is focused on natural language understanding, currently, I have three research threads: 1: Applying linguistic knowledge bases to fundamental NLP tasks. 2: NLP applications in healthcare, legal, criminology, and media. 3: User profile-based emotion analysis based on text and multimodality data.

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.
