Abstract: In a system in which documents are generated dynamically in response to user requests, historical data is collected regarding data retrieval subtasks, such as service requests, that are performed to generate such documents. This data is used to predict the specific subtasks that will be performed to respond to specific document requests, such that these subtasks may be initiated preemptively at or near the outset of the associated document generation task. A subtask that would ordinarily be postponed pending the outcome of a prior subtask can thereby be performed in parallel with the prior subtask, reducing document generation times. In one embodiment, the historical data is included within, or is used to generate, a mapping table that maps document generation tasks (which may correspond to specific URLs) to the data retrieval subtasks that are frequently performed within such tasks.

Abstract: A facility for automatically initiating product replenishment is described. The facility receives an indication of an order by a consumer for a first item having a first date, such as the date on which the first item was placed or fulfilled. The facility then determines a target date for replenishment based upon the identity of the first item. On the target date, the facility provides to the consumer an indication that the first item should be replenished. The indication includes a control useable by the customer to request replenishment of the first item. When this control is operated by the consumer, the facility receives an indication that the control is used by the consumer to request replenishment of the first item. In response to receiving indication the facility orders a second item to replenish the first item.

Abstract: A network-based transaction processing system allows online users to flexibly and efficiently make payments using a combination of different payment instruments. The system includes a user interface through which each user can define one or more personal payment plans. Each such payment plan specifies a plurality of payment instruments, and includes rules that specify how the monetary amount associated with a transaction is to be divided among these payment instruments. These rules may be non-transaction-specific, such that a user can re-use a payment plan over time to complete multiple transactions. In one embodiment, a user can specify an order in which the payment instruments are to be applied, and can specify per-transaction maximum monetary amounts to be charged to specific instruments.

Abstract: An electronic catalog system, which may be implemented as a web site or another type of interactive system, presents context-sensitive information to customers reflective of their prior orders. In one embodiment, when a customer requests an item detail page for a particular item, the system may supplement the item detail page with information reflective of one or more related orders previously placed by the customer. This information may include, for example, an indication that the customer previously ordered this item or a related item, and may include information, such as status information, regarding such previously placed order(s). If the customer previously ordered a related item, the information provided on the item detail page may include an indication of whether the previously ordered item is compatible or interoperable with the item being viewed.

Abstract: A computer-implemented service analyzes purchase histories and/or other types of behavioral data of users on an aggregated basis to detect and quantify associations between particular items represented in an electronic catalog. The detected associations are stored in a mapping structure that maps items to related items, and is used to recommend items to users of the electronic catalog.

Abstract: A distributed auction system allows remote bidders to interactively participate by computer in live auctions conducted on-site by an auctioneer. A client program that runs on the computers of the remote bidders displays real time auction status information extracted from status messages, and provides functionality of the remote bidders to submit live bids that are based on such status information. A network of nodes may be used to filter out invalid bids from the remote bidders so that such bids need not be processed by an auction server.

Abstract: A method and system for bidding on multiple auctions. The multiple auction bidding system allows a user to define various models for bidding at multiple auctions. The bidding system then automatically places bids on behalf of the user. The bidding rules may specify to win at most one of multiple auctions at the lowest price or to bid at an auction only if successful at bidding at another auction.

Abstract: Various methods are disclosed for monitoring user browsing activities, and for using such information to provide item recommendations to users. In one embodiment, a monitoring component of a merchant's Web site maintains a record of products viewed by each user during a current browsing session—preferably based on visits to product detail pages. A recommendations component uses the resulting history of viewed products to identify additional products to recommend, preferably using a pre-existing table that maps products to related products. In one embodiment, this table is generated by periodically analyzing user browsing histories to identify correlations between purchases, viewing events, and/or other actions performed with respect to particular products. The recommended items may be displayed together with an option to individually deselect the recently viewed items on which the recommendations are based.

Abstract: Customers make purchases from online merchants using personal information, such as payment and shipping information, stored with an online information service. The merchants may optionally report information about each customer's purchases back to the information service, which may incorporate the information into a history page that is accessible to the customer. The information service may also use the aggregated purchase history data to generate an “interests” profile for the customer, which may be disseminated to the merchants and used to customize their web sites. The web pages of the merchants may include a reference to an object, such as a graphic, that is served by the information service. For customers that are registered with the information service, this object may be customized with the name of the customer, and may be selectable by the customer to make single-action purchases.

Abstract: Various computer-implemented services are disclosed for increasing the utility of electronic wish lists, and for assisting users in making gift purchases. One such service automatically notifies a user when an item being accessed in an electronic catalog is on, or is similar to an item on, an electronic wish list of an “affiliated” user. The affiliations may be created explicitly by the users (e.g., by completing an online form), and/or implicitly based on actions performed by the users (e.g., when one user purchases a gift for another user). Another service automatically reminds a first user who is affiliated with a second user when a known or inferred gift-giving event of the second user is approaching. The reminder may include a link to a wish list of the second user, and/or may include or provide a link for viewing personalized gift recommendations for the second user.

Abstract: A computer system for conducting electronic commerce. The system provides multiple electronic shopping carts for each user. Each electronic shopping cart has an indication of items currently within the electronic shopping cart and billing and shipment information. The system generates a display that identifies each of the electronic shopping carts and sends the generated display to a user computer system. The system then receives a selection of one of the identified electronic shopping carts from the user computer system and receives a selection of an item from the user computer system. In response to receiving the selection of the item, the system adds the item to the selected electronic shopping cart. The system then receives an indication to checkout the items in the selected electronic shopping cart from the user computer system.

Abstract: A computer-implemented service analyzes purchase histories and/or other types of behavioral data of users on an aggregated basis to detect and quantify associations between particular items represented in an electronic catalog. The detected associations are stored in a mapping structure that maps items to related items, and is used to recommend items to users of the electronic catalog. The items may include products and/or categories of products.

Abstract: A computer-implemented service acts as an intermediary between merchant sites and users thereof, and enables the users to purchase items on the merchant sites without having to create accounts with such sites. A user may invoke the service from a web page of a merchant site, and complete a purchase transaction, without having to browse away from the merchant site. The service may either forward the user's payment information to the merchant's system to enable the merchant to charge the customer, or may charge the user on behalf of the merchant. In some implementations, the service enables users to make single-action purchases from the merchant sites.

Abstract: A method and system for authenticating users while conducting an auction via a computer system. The system can automatically authenticate users who have previously registered with the auction system and who have enabled automatic authentication. When a user is registered, the system may store authentication information in a cookie on the user's computer. When the user decides to perform a transaction (e.g., list item auction or place a bid for an item) that requires authentication, the system retrieves the stored authentication information. If automatic authentication is enabled, then the system allows the transaction to proceed without manual authentication. If, however, automatic authentication is not enabled or the system does not recognize the stored authentication information, then the system requests manual authentication. The use of automatic authentication allows a user to enter information relating to a transaction without manually entering any identification information.

Abstract: A computer process is disclosed for selecting items to present or recommend to users based on the referring sites accessed by such users. The process includes tracking referrals of users from referring sites to a target site, and recording the item selections of the referred users from an electronic catalog of the target site. The process may also include analyzing the recorded item selections of the users to identify, for a particular subset of the referring sites, a set of items that correspond to group preferences of users referred to the target site by the subset of referring sites. These identified items may thereafter be presented to users who access a site that is a member of the subset of referring sites.

Abstract: Processes and systems are disclosed for enabling a user to purchase a digital product from a first computer system (e.g., a merchant web site), and to then initiate electronic delivery of the digital product from a second computer system without revealing personal information to the second computer system or its operator. In one embodiment, the user initiates the anonymous delivery from the second computer system using a link received from the first computer system. The first and second computer systems communicate with each other to track fulfillment/delivery statuses of orders, and to limit the number of times the user can download the purchased digital product from the second computer system.
