I am working on

  • KG4Core – a knowledge graph infrastructure for supporting bioinformatics research, which integrates structured background knowledge (e.g., drug bank, uniprot, sider), electronic health records (e.g., CRIS data), and Linked Data(e.g., linked life data).
  • EBEncoding – efficient bitwise encoding for temporal/longitudinal (medical) data analytics – particularly on Adverse Drug Event analytics on CRIS data.
  • NapEasy – automated PDF highlighting tool to support faster curation of case studies and reviews on Parkinson’s and Alzheimer’s disease.

Short Bio  Dr Honghan Wu is a research fellow in Department of Biostatistics and Health Informatics of King’s College London. His current research focus is on annotating, analysing and searching large scale healthcare data by utilising text technologies and Knowledge Graph techniques. Before current post, Dr Wu got two Marie Curie Fellowships in two EU IAPP projects of K-Drive (in Aberdeen University, UK) and TEAM (in ELIKO, Estonia). He holds a PhD in computer science from the Southeast University. Dr Wu’s expertise is on dealing with huge volume and heterogeneous Semantic Web data, including combining information retrieval and data mining techniques with semantic technologies, including semantic search, summarisation and compression of RDF data, as well as query generation and query answering.
