Abstract

Profiles are the basis for individual communication, because they provide information about website users. Ontologies represent a possibility for modeling user profiles. The ontology development within the paper is based on a concept which shows firstly criteria of segmentation and secondly product programs of a retailer. A meta-ontology is built to enforce a mapping between the ontologies. Due to ontology-based recommendations it is obvious that they imply an additive character regarding conventional recommender systems. Therefore, the possibility arises to increase the turnover and to achieve customer satisfaction. But, the usage of ontology-based profiles is currently disputable relating to economic efficiency.
