A method of predicting the compatibility of at least one item of interest to a user of a web-based system. The method includes the steps of providing a survey of items for rating by the system user, collecting a set of ratings for the survey of items from the system user, collecting a set of ratings for the survey of items from each of a plurality of raters, calculating a correlation coefficient between the system user and each of the plurality of raters to obtain a set of correlation coefficients for the survey of items, selecting a group of raters from the plurality of raters, the group of raters selected on the basis that each member of the group of raters has provided a rating of the at least one item of interest and predicting the compatibility of the at least one item of interest to the system user from the ratings provided by the group of raters and the correlation coefficients calculated between the system user and each of the group of raters.
