We examine the influence of the d-parameter as powerful personalization instrument for the Preference XPath search engine. Using a heuristic approach we present a possibility to deliver not only the qualitative best matching objects but also the desired amount of data to the user. Performing a series of test queries on proper e-catalog data, we demonstrate the effectiveness of our approach.enText/Conference Paper1617-5468
