Abstract

While the Semantic Web has evolved to support the meaningful exchange of
heterogeneous data through shared and controlled conceptualisations, Web 2.0
has demonstrated that large-scale community tagging sites can enrich the
semantic web with readily accessible and valuable knowledge. In this paper,
we investigate the integration of a movies folksonomy with a semantic
knowledge base about user-movie rentals. The folksonomy is used to enrich the
knowledge base with descriptions and categorisations of movie titles, and
user interests and opinions. Using tags harvested from the Internet Movie
Database, and movie rating data gathered by Netflix, we perform experiments
to investigate the question that folksonomy-generated movie tag-clouds can be used to
construct better user profiles that reflect a user's level of interest in
different kinds of movies, and therefore, provide a basis for prediction of
their rating for a previously unseen movie.
