A two-stage graph mining scheme for novel item recommendation is proposed. The first stage extracts preference attribute as a topic-rating vector using a graph mining technique given a data set of item ratings, and the second stage predicts one’s preferred items out of novel domains using another graph mining procedure based on the extracted preference. We compared the prediction performance of four possible implementations using a data set of ratings of TV programs. The data set contains 368,400 ratings, ranging from -2 to +2 (negatives to positives). Each rating was provided by 1,228 subjects against 300 TV programs from the NHK On-Demand service. To describe semantic relationships between the items, we appended 1,000 metadata-nodes to each graph, which are extracted from the outline field of the Electronic Program Guide contents. |
