CiteSpace II visually maps scientific literature trends and patterns in bibliographic databases. This knowledge discovery tool aids in identifying pivotal research and emerging topics within specific fields like medical informatics.

Area of Science:

  • Bibliometrics
  • Information Science
  • Scientific Visualization

Background:

  • Bibliographic databases contain vast amounts of scientific information.
  • Identifying trends and pivotal research within these databases is crucial for scientific advancement.
  • Existing methods for knowledge discovery may lack effective visualization capabilities.

Purpose of the Study:

  • To describe and evaluate CiteSpace II, a Java application for visual knowledge discovery in bibliographic databases.
  • To demonstrate the application of CiteSpace II for visualizing trends in the field of medical informatics.
  • To identify pivotal documents, areas of specialization, and emerging research topics using visualization.

Main Methods:

  • Developed CiteSpace II, a Java application for visual exploration of bibliographic data.

  • Utilized datasets from PubMed and Web of Science (WOS) covering medical informatics publications (1964-2004).
  • Applied progressive knowledge domain visualization techniques, including document-term co-citation and MeSH term co-occurrence analysis.

    • Main Results:

    • CiteSpace II successfully generated visualizations of the medical informatics field.
    • Visualizations enabled the identification of highly cited documents and key research areas.
    • Emerging research trends within medical informatics were discernible through the visualization approach.

    Conclusions:

    • CiteSpace II is an effective tool for visual knowledge discovery and trend analysis in scientific literature.
    • The system facilitates the identification of pivotal research and specialization areas.
    • The approach has practical applications for bio-medical research and understanding domain evolution.
