Research Interest
I am mainly interested in:
- Data engineering, knowledge graph construction & ontology building
- Knowledge graph integration using machine learning & large language models
- Novel data integration approaches for supporting NLP tasks such as entity summarization & keyphrase extraction
- Large language model for supporting data integration tasks and vice versa
Reviewing
My limited free time is partly consumed by tasks such as reviewing, for instance,”
