Aggregating Recommendations using RDF



This paper describes an early implementation of an XML/RDF-based metadata service environment, focussing on the convergence of cataloguing, bookmarking, recommendation and filtering applications facilitated by XML and RDF. The recommendation system uses RDF to store user recommendations and annotation data, using the RDF syntax and the Dublin Core vocabulary. It is entirely configurable also using RDF/XML. The display of the recommendations is left open, although they may be displayed using an RDF display tool which opens up the possibility of aggregating diverse recommendations, remote or local. The paper then discusses several different models of metadata aggregation with respect to the incentives of contributors to create high-quality metadata, and the evaluation strategies of the aggregation sites.
