Research Interests#

At present, my research is mainly about automatic extraction, semantic fusion and intelligent application of multi-source heterogeneous knowledge with big data:
  • Deep knowledge representation: representation learning
  • Heterogeneous knowledge fusion: ontology matching, entity alignment, truth inference
  • Intelligent software R&D: knowledge-enhanced search/QA/recommender systems
  • Cross-research in medicine: with National Institute of Health Data Science at Nanjing University
