determining the degree of similarity between said first item and each of said plurality of rated items of said record;

determining the degree of similarity of the rating of said first item and each of said plurality of rated items of said record;

selecting at least one of said plurality of rated items on the basis of the highest determined degree of similarity between said first item and each of said plurality of rated items of said record and on the basis of the highest determined degree of similarity of the rating of said first item and each of said plurality of rated items of said record.

8. A method according to claim 7, wherein the step of determining the degree of similarity between said first item and each of said plurality of rated items of said record comprises the steps of:
