Order-wise correlation dynamics in text data

Abstract

We applied information geometry to treat the correlation beyond second order in network co-word analysis. We also defined the meta-level dynamics of these correlations based on all hierarchical combination of the variables, in order to encompass all possible relations. The result shows a rich variety of dynamics depending both on the order of correlation and the order of meta-level dynamics. © 2009 Springer-Verlag Berlin Heidelberg.
