We present an approach for propagation of user interests in ontology-based user models
taking into account the properties declared for the concepts in the ontology. Starting
from initial user feedback on an object, we calculate user interest in this particular
object and its properties and further propagate user interest to other objects in
the ontology, similar or related to the initial object. The similarity and relatedness
of objects depends on the number of properties they have in common and their corresponding
values. The approach we propose can support finer recommendation modalities, considering
the user interest in the objects, as well as in singular properties of objects in
the recommendation process. We tested our approach for interest propagation with a
real adaptive application and obtained an improvement with respect to IS-A-propagation
of interest values. |
