We present a new multidimensional model with textual dimensions based on a knowledge structure extracted
from the texts, where any textual attribute in a database can be processed, and not only XML texts.
This dimension allows to treat the textual data in the same way as the non-textual one in an automatic
way, without user’s intervention, so all the classical operations in the multidimensional model can been
defined for this textual dimension. While most of the models dealing with texts that can be found in the
literature are not implemented, in this proposal, the multidimensional model and the OLAP system have
been implemented in a software tool, so it can be tested on real data. A case study with medical data is
included in this work.
