Wei Liu

Wei Liu is an Assistant Professor at the University of Western Australia, and currently the Lab Coordinator for Adaptive System Group. She obtained her PhD from the University of Newcastle on Multi-Agent Belief Revision, Australia in 2003. Her current research interest is on ontology learning to bootstrap agent knowledge base. Dr. Wei Liu’s research strength lies in ontology learning and data-driven ontology change. She leads the work on developing automatic and semi-automatic ontology learning system from 2004, which addresses the cold-start issues (labour intensive and time consuming) of manual ontology engineering. The research contributes significantly to the investigation of emergent semantics through text mining. The first paper reporting the techniques and the system modules won one of the best papers in the conference and was invited for journal publication. The techniques developed including co-occurrence analysis to identify taxonomic and non-taxonomic relations, and spreading activation to identify the core, extended, and peripheral concepts. Information network analysis and clustering algorithms are also developed to measure the evolution of an ontology in both temporal and spatial scope.
