Abstract: This article reports on an empirical study of the trends and patterns 
of research activities in Geographic Information Science (GIScience) during the 
years 1997-2007. The GIScience research priorities identified by the University 
Consortium of Geographic Information Science (UCGIS) were used as guidelines 
to examine the 985 research articles published in six well-recognized academic 
journals. Latent Semantic Analysis (LSA) was employed to investigate the 
association among the different GIScience research themes. The spatial and 
temporal patterns of the association between the publications and the different 
GIScience themes were examined to show the development of GIScience 
research during the study period. Furthermore, correlation analyses between 
the publications were conducted following the LSA results to reveal GIScience 
research networks, including the networks of the published articles and those 
formed by the research places. In this article, we applied an approach that was 
developed within information science to depict what GIS research activities 
were conducted when and where and how they connect to each other through 
sharing common research themes. The related findings pave the way for future 
efforts to describe the paradigm of GIScience as well as the pattern of 
GIScience research.
