Acquisition and Representation of User Preferences Guided by an Ontology

TL;DR

This paper presents a method using OWL2 ontologies to acquire and represent user preferences in a formal CP-Net framework, demonstrated through a university canteen case study.

Contribution

It introduces a novel approach combining domain ontology with preference modeling to enhance preference acquisition and representation.

Findings

Ontology-based preference acquisition is feasible.

Preferences are enriched with domain knowledge.

Application demonstrated in university canteen context.

Abstract

Our food preferences guide our food choices and in turn affect our personal health and our social life. In this paper, we adopt an approach using a domain ontology expressed in OWL2 to support the acquisition and representation of preferences in formalism CP-Net. Specifically, we present the construction of the domain ontology and questionnaire design to acquire and represent the preferences. The acquisition and representation of preferences are implemented in the field of university canteen. Our main contribution in this preliminary work is to acquire preferences and enrich the model preferably with domain knowledge represented in the ontology.
