Abstract

To identify the position of traditional herbal medicine in dementia research field using mapping technology. Keywords for dementia and traditional herbal medicine for treating dementia were used to extract scientific articles from the Web of Science database from January 2000 to July 2010. A co-occurrence matrix was created based on the concurrent set of author's keywords occurring in each scientific article, and technology network maps were created from similarity index matrices.
