Abstract: Artificial intelligence is used to identify significant records in a computer database. The records in the database are ordered in accordance with a first factor. Records in the database which have a position less than a first threshold are identified to provide second-level records. At least some of the second-level records, but only the second-level records, are arranged into a plurality of groups based on a second factor. For at least one of the groups, the second-level records in the group are then ordered in accordance with a third factor. At least one second-level record in the group is selected, where the selected second-level record has a position greater than a second threshold. Information regarding the selected second-level record is then provided, such as to a client device.

Abstract: Opaque offerings of items conceal at least one attribute of the items from customers, typically a brand associated with the items. Such offerings usually include a generic description of the items and an opaque price that is typically lower than a standard offered price for the items. By identifying customers who may have an interest in such items, and tailoring opaque recommendations of such items to such customers, an online marketplace may increase the likelihood that such items will sell to customers while protecting an owner of a brand of such items from any negative implication or connotation that may be associated with offering such items at substandard prices.

Abstract: Techniques and systems provide transparency in hidden transaction details for an item. A process comprises crawling one or more electronic marketplaces to identify an item presented in an item offering, extracting offer details in the item offering, emulating an ordering process for acquiring the item to determine transaction details that are revealed after the ordering process is initiated, and presenting at least a portion of the transaction details with item and offer details. In some embodiments, the offer details include a list price for the item, and the transaction details include a true price for the item with a hidden cost included in the true price. The hidden cost may be compared to a threshold to determine if it is excessive. A seller identified with the item offering may be designated with a rating indicative of a reputation of the seller for providing excessive hidden costs with item offerings.

Abstract: The present invention provides systems and methods for determining the originality of data content. In one embodiment, the determined originality of a particular item (e.g., a book) as compared to one or more other items can be used as a factor in recommending the item to a user. For example, in one embodiment, upon a user's selection of an item (e.g., a book), one or more items that have content most diverse from the selected item are determined and provided to the user. In another embodiment, various versions of an item are compared to each other to determine how content in each version differs from that in another version. In another embodiment, content in a collection of items are compared against content from publicly (freely) available sources (e.g., web pages) to determine the originality of the content in the collection of items.
