<p>A user opinion system and customer preference system (1000) employs a user opinion database (4) and opinion prediction algorithms for predicting various facts and opinions. A combination of parallel opinion predictions are used to determine a single parallel-combinative prediction. Product opinions (17) are predicted based upon predicted attribute opinions (16, 211, 213, 215, 217), known attribute opinions (16, 210), product attributes (11, 246), known user attributes (10, 256) and other product opinions (17). Attribute opinions (16) are predicted based on attribute opinions (16, 210, 211, 213, 215, 217) (including known and/or predicted attribute opinions), know attribute opinions (16, 210), product attributes (11), known user attributes (10, 256) and other product opinions (17). Price versus demand curves (sometimes herein called price-demand curves) are based on data in a user opinion database (4).</p> |
