摘要： A method for category search. The method includes determining semantic relationships between terms in a corpus; obtaining, from an expense category hierarchy and for an expense category, a collection of keywords; and expanding the collection with a related keyword according to a semantic relationship of the relationships between the related keyword and a preexisting keyword in the collection. The method further includes extracting a segment from a description of a first historical transaction by a user of the financial product; and adding the extracted segment as an additional keyword to the collection when, for the extracted segment, the minimum of a first and a second confidence-interval bound calculated for a first transaction score and a first user score, respectively, satisfy a first threshold; and returning the name of the expense category in response to a user submitting a first query that comprises at least one the keyword in the collection.

摘要： A method for preventing unintended discounts and frauds in an intelligent electronic shopping system includes providing a user with a first discount, a second discount, and a third discount from a service provider and storing rules in a promotion rule module, wherein the rules define that the first discount is combinable with the second discount or the third discount and that the second discount and the third discount are not combinable with each other. A first price for the order is computed based on the combination of the first discount and the second discount. A second price for the order is computed based on the combination of the first discount and the third discount. The user selects the first price or the second price to pay for the order.
