Publication Distribution in Subjects by Year

13

Big Changes in Dominant Subject Areas over Time

14

Scholarly communication of IS in Korea has been moving to the research of analytics and applications from the technology and system.

Change of Subject Portion by Two Periods

• P-2: Informetrics, Information Organization, etc.

• P-1 : Designing & Evaluation, Information System, Services, etc.

15

Subject Portion of the Highly Posted Subcategories

• P-2: Bibliometrics, Trends Analysis, Ontology, Digital Archiving, Document Processing, etc.

• P-1: Usability , Library System, etc.

16

Increasing/Decreasing trends in research topics

• Increasing Domains:Library, Users, Retrieval, Web, Services, Digital, Korea, Metadata, Ontology• Decreasing Domains :

Evaluation, Model, Use, Knowledge, Management, Digital, Technology, Internet

17

IS research in Korea has been studying application of IS on Library domains with service-oriented approaches instead of technology-oriented approach
