Abstract: A system and device is presented for wine categorization in a database that links vintages into a wine model, and nodes in the wine model into wine categories. Further links relate foods to nodes in the wine categories, thereby allowing user queries relating to foods to retrieve wine vintages that experts consider appropriate for that food.

Abstract: A kiosk is presented that filters user search results into a recommended subset of available products as determined by multiple selection criteria selected by a retailer. Each selection criterion is applied separately to the user search results by first comparing the search results against a threshold value. Those products that meet this threshold value are then filtered against a reference profit margin value, with products having a profit margin less than the reference being filtered from the results. Finally, the results are sorted by a variable associated with the selection criteria, with the top products being returned as a result set for each selection criteria. The result sets from all selection criteria are then merged together into a display of recommended products.
