Professor Dr. Xiaohui Tao holds a distinguished position at the University of Southern Queensland's (UniSQ) School of Mathematics, Physics, and Computing in Australia. Currently, he is the Computing Discipline Leader and presides as the Chair of the ICT Programs’ Governance and Leadership Committee at UniSQ. Before assuming these pivotal roles, from 2016 to 2021, he provided esteemed leadership as the Director of various academic programs, including the Master of Data Science, Master of Information Technology, and Master of Science at UniSQ.
An esteemed scholar in Artificial Intelligence, Dr. Tao's research encompasses a wide spectrum, including but not limited to data analytics, machine learning, knowledge engineering, natural language processing, and health informatics. His academic contributions are well-recognized with over 190+ publications in eminent journals such as TKDE, TOIS, TIST, INFFUS, IPM, and notable conferences including AAAI, IJCAI, EMNLP, ICDE, and CIKM. Beyond individual research, he spearheads a prominent research group that prioritizes innovative algorithms and systems with significant real-world applications. Additionally, he has exhibited exceptional mentorship, having successfully supervised eight doctoral candidates to completion.
Dr. Tao's contributions to the academic community have been acknowledged with prestigious awards like the Australia Research Council Grant and the Australian Endeavour Research Fellowship, as well as recognition from international conferences, namely ACMHN’22, BESC’22, BI’21, WI-IAT’20, and WISE in 2020 and 2019.
A Senior Member of both the IEEE and ACM professional bodies, Dr. Tao also contributes as the Vice Chair of the IEEE Technical Committee on Intelligent Informatics (TCII). His editorial endeavors include serving as the Editor-in-Chief for Elsevier's Natural Language Processing Journal, the TCII Bulletin, and Web Intelligence (CCF C). He has further enhanced his profile by serving in key roles in conferences such as CBD’22, WI-IAT’21, BESC’21, and more.
Dr. Tao concluded his Ph.D. in Information Technology from the Queensland University of Technology, Australia, in 2009.
Privacy Preservation over 5G and IoT Smart Devices This project aims to investigate privacy preservation protocols in a 5G integrated IoT environment through an analysis of the depth of smart-device use in common smart domains. 5G’s addition to IoT-based smart devices will be effectively deployed and utilised by a large majority of individual and organisation-based users. The knowledge-based ontology and tools developed in the project will help form the new privacy preservation mechanisms that are required for the 5G enabled environment. The construction of new AI-based tools and testing facilities as well as the generation of new knowledge in the field of privacy preservation and collaboration between universities are expected outcomes of this project.
Computational Social Science for Online Mental Health using Artificial Intelligence Many people are suffering from mental issues without knowledge of it. As a result, they are unable to access to appropriate helps. Finding and helping these people have motivated us in the research proposed in this project. It will model the behaviour of online social network users by analysing their expressions using natural language processing and machine learning techniques, and alert potential mental issues adopting data mining techniques like outlier detection. A knowledge base conceptualising mental health domain knowledge will provide foundation to these tasks. With the outcome of the work, clinical decision support systems can be designed to assist psychologists and social workers in diagnose and help people with mental issues at early stage; tools like mobile apps can be developed to help guardians like parents to keep an eye on their children's mental health proactively without breaching their privacy. People suffering from mental issues can also benefit from the tools by monitoring their own mental health easily, so that they could pull back at early stage and avoid falling into more severe circumstances if anything wrong is happening. The proposed research will make potential theoretical contributions to deepening our understandings of mental health, as well methodological contributions to knowledge engineering, natural language processing and data analytics.
Artificial Intelligence and Big Data Analytics for P4 Medicine Recent successes in Biotechnology and Artificial Intelligence have been driving the transformation of medical practice from traditional untargeted, reactive and experience-based to targeted, proactive and evidence-based. P4 (Predictive, Preventative, Personalised and Participatory) medicine will provide cost-effective disease care, reduce the incidence of diseases and replicate the innovation cycle of systems medicine on a large scale, and is believed "a revolution of medicine / healthcare practice". This research is focused on predictive and personalised medicine by predicting potential diseases based on patient's personal health status using Machine Learning techniques. It will further support physicians' clinical decisions by providing prescription re-check and suggesting treatment plans using knowledge bases and information retrieval techniques. To achieve these goals, study of massive data in heterogeneous types is essential. The research will help develop our capability of proactive and evidence-based medicine and help design clinical decision support systems.
Machine Learning and Knowledge Engineering for Recommender Systems Recommender systems predict the interests and preferences latently held by a user and try to deliver the user targeted and personalised recommendations on products and services. Using collaborative information filtering and user profiling techniques, recommender systems have been greatly successful and widely used in many large organisations including Netflix, Amazon, Facebook, and LinkedIn. However, from research perspective many challenges stand still and deserve great endeavour from the research community, such as Cold Start, Information mismatching and overloading, Scalability, Diversity, Privacy, and shilling attacks, etc. This research project aims at making a breakthrough in recommender systems adopting stat-of-the-art techniques in Machine Learning (e.g., deep learning) and Knowledge Engineering (e.g., knowledge graph).
