Image Number 7 for United States Patent #8117085.
Data mining systems and methods are disclosed for generating data that is helpful to users in selecting between items represented in an electronic data repository, such as an electronic catalog. One disclosed data mining method generates pairwise comparison data for particular pairs of items based on aggregated user activity data reflective of item consideration actions and item selection actions of users. Another data mining method uses item viewing histories and item purchase histories of users in combination to assess whether particular items are good candidates for being purchased or recommended in combination. Statistical data resulting from one or both of these data mining methods may be presented to users (e.g., on electronic catalog pages) to assist users in making informed item selection decisions.
