Bio-description

  • Chris Khoo is an associate professor at the Wee Kim Wee School of Communication & Information, Nanyang Technological University, Singapore. He teaches courses in knowledge organization/representation (focusing on ontology, knowledge graph, graph database and graph visualization), and data analytics (data mining and social media analytics). He obtained his PhD at Syracuse University, an MSc in Library & Information Science at the University of Illinois, Urbana-Champaign, and BA at Harvard University. He has also worked for several years as a science reference librarian at the National University of Singapore Libraries. His main research interests are in knowledge graph and graph visualization, text mining (information extraction, text summarization and sentiment analysis), and multidisciplinary study of academic writing & thinking.
  • His PhD thesis was on “Automatic Identification of Causal Relations in Text and Their Use for Improving Precision in Information Retrieval.” He was the editor of the Singapore Journal of Library & Information Management from 1997 to 2002, and editor of the LIBRES e-journal from 2014 to 2022.
  • Hobbies: Chris plays the violin and piano, listens to classical music, and is an avid reader of science fiction and fantasy.

Research Interests

Chris’ main research interests are in

  • Natural language processing & text mining:
    • Multidocument summarization of research papers; automatic literature review generation
    • Information extraction from research articles, biographies, etc.
    • Automatic sentiment analysis.
  • Knowledge organization
    • Knowledge graph for digital humanities content, digital heritage collections, and research data repository.
    • Scientific knowledge graph to represent the research results of research papers and their argument-information structure – to support multi-document summarization and knowledge discovery.
  • Visualization interfaces for digital heritage collections and knowledge graphs.
  • Academic writing, reading & thinking: Multidisciplinary study of academic writing, and exploring the relations between reading, thinking and writing. Development of an Academic Writing Assistant Web application, focusing on argument-information-linguistic structure.
