Abstract-This study proposes that keyword networks can be formulated from research publications and used to examine how the keywords have been connected with each other to create new concepts. For the purpose of empirical analysis, the keyword networks are organized based on the miss publication information from 1999 to 2008, the analysis of which reveals a number of notable results. First, the MIS field has changed so quickly that many new concepts and keywords have been introduced, and the connection of keywords is highly clustered. Second, the keyword network shows a clear power-law degree distribution, indicating that, the more popular a keyword becomes, the more that the keyword is selected by researchers and it is associated with other keywords of concepts to create new ideas. This evidence implies that the important keywords analyzed from a network perspective are different from those analyzed from a popularity perspective. Also, the interdisciplinary keywords have the potential to create new research fronts in the MIS field. This suggests that analysis from a network perspective is needed to determine the changes in important keywords over time and to better understand the process of know ledge evolution.
