چکیده
Personalization includes the adaptation of database queries according to the user’s needs, wishes and situation. We examine the influence of the dparameter as powerful personalization instrument for the Preference XPath search engine.

Performing a series of test queries on proper e-catalog data, we demonstrate the effectiveness of our approach.
