In this study we have focused on the problem of mapping the dynamics o
f co-word-matrices from subsequent time periods. Methods for mapping d
ynamics are important for following trends in research. We have explor
ed the possibilities of a three way multidimensional scaling method, I
NDSCAL. We are especially interested to find relations between adverse
drug reactions and other words in co-word-matrices from a medical fie
ld. Second we want to explore whether the relations between adverse dr
ug reactions and other words have changed in subsequent time periods.
The results show that INDSCAL can be a useful tool for mapping dynamic
