Abstract

There are two main techniques used to capture an individual's personal preferences in order to make recommendations to them about various items of interest: feature-based and clique-based. In this paper we present an approach that can use either technique or a hybrid of the two. Features are captured in the granularity knowledge formalism, giving the feature-based approach more representational power than in most systems. But, the most novel feature of the approach is its ability to use a hybrid technique, which aims to combine the advantages of both feature-based and clique-based approaches while minimising the disadvantages. The hybrid technique also allows for the construction of a personalised explanation to accompany the recommendation. A prototype for the movie domain, MovieMagician, has been developed. A formative evaluation of this prototype has been undertaken in all of its modes: feature-based, clique-based, and hybrid. Other evidence of effectiveness has also been gathered.
