The invention relates to a method of personalizing organization of a product set. In the method a first matrix is established, the first matrix being populated by ratings associated with a first plurality of v viewers in a content distribution system and a second plurality of p products each of which is a content item, the first matrix having dimensions v and p, each entry in the first matrix comprising either an empty entry or a rating indicating viewer interest in a content item. The matrix is bi-clustered to produce a second matrix. The second matrix comprising a matrix of ratings comprising a grouping of the viewers according to similarity of products chosen by the viewers and a grouping of the products according to similarity of viewers who viewed the products, the second matrix comprising typical ratings that viewers in a given group have given to products in a given group. Viewers are associated into groups of viewers based on the viewer grouping in the second matrix. Refinement parameters of products are selected where the refinement parameters comprising a sub-set of a set of metadata parameters associated with the products. For each group of viewers, the refinement parameters are ranked with respect to mutual information between a refinement parameter value and a product choice within each group of viewers. An individual viewer is then presented with a set of the refinement parameters, the refinement parameters ordered within the set by a rank corresponding to the viewer group the individual viewer is associated with. In response to a viewer choice of the refinement parameters interactively performing at least once selecting a sub-set of products from the product set, the sub-set of products comprising products with metadata matching the refinement parameters selected by the individual viewer and presenting the individual viewer the selected sub-set of products and a set comprising the refinement parameters not including the refinement parameters already selected by the individual viewer. |
