In this study the authors have focused on the problem of mapping the dynamics of co-wordmatrices from subsequent time periods. Methods for mapping dynamics are important for following trends in research. They have explored the possibilities of a three way multidimensional scaling method, INDSCAL. They are especially interested to find relations between adverse drug reactions and other words in co-word-matrices from a medical field. Second we want to explore whether the relations between adverse drug reactions and other words have changed in subsequent time periods. The results show that INDSCAL can be a useful tool for mapping dynamics. (Author/publisher
