Various computer-implemented services are disclosed for assisting users in selecting items from an electronic catalog, and for selecting merchants with which to conduct transactions. One such service enables users to share information about their respective purchases with other users. Another service enables users to share information regarding the merchants with which they have conducted transactions.

Techniques are described for facilitating interactions between computing systems, such as by performing transactions between parties that are automatically authorized via a third-party transaction authorization system. In some situations, the transactions are programmatic transactions involving the use of fee-based Web services by executing application programs, with the transaction authorization system authorizing and/or providing payments in accordance with private authorization instructions previously specified by the parties. The authorization instructions may include predefined instruction rule sets that regulate conditions under which a potential transaction can be authorized, with the instruction rule sets each referenced by an associated reference token. After one or more of the parties to a potential transaction supply reference tokens for the parties, the transaction authorization system can determine whether to authorize the transaction based on whether the instruction rule sets associated with the reference tokens are compatible or otherwise satisfied.

An interactive system enables users to generate and submit lists of items (e.g., products) for viewing by other users. The user-generated lists are selectively suggested to users of the system based on their respective behaviors, such as their item viewing activities, searches, and/or item purchases. The system may monitor the behaviors of users who access particular user-generated lists, and based on the monitored behaviors, generate measures of the effectiveness of particular lists (e.g., effectiveness at driving item purchases). The measures of effectiveness may be considered in selecting particular lists to suggest.

Information retrieval systems and methods are disclosed for presenting items of interest to a user of a computer-based data repository, where the items are presented in the form of lists generated by other users. Users of a data repository may generate lists of items from the repository that are accessible by other users. In various embodiments, users generating lists may add supplemental commentary about the items and other personalizing information. The information retrieval systems and methods store the user-generated lists for future presentation to other users. When a user of the data repository submits a search query, items returned in the query's results are interpreted to be items of interest to the user, and in response, one or more lists determined to be similar to the items of interest are presented to the user.

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.

A message originator may generate messaging data for selective communication by a messaging provider via an interface generated by a browser software application. The user may also interact with various content providers such that event data is generated based on the user interaction with each content provider. The messaging provider can then obtain the messaging data and the event data to determine a target set of messages to be published. Additionally, the messaging provider can select a set of message recipients to receive, or otherwise access, the target set of messages based on filtering criteria submitted by the message originator, content provider, service provider, and/or message recipients. Credit may be allocated based on activity associated with the communicated messages. The messaging provider may also facilitate additional interaction between the message originator and the message recipients including the initiation of additional communication channels.
摘要:
A computer-implemented service analyzes collected data reflective of actions of users of an interactive system to identify items that are significantly more popular in specific user communities than in a general user population. The communities may, for example, include email-based communities (e.g., all users with email addresses associated with a particular company or other organization), shipping address based communities (e.g., all users with shipping addresses in Seattle), and/or communities based on other types of user attributes. The results of the analysis may be exposed to users to assist users in making item selection decisions, and/or may be used to provide item recommendations to users.

Prominence data resulting from user interaction with a hyperlink on a page may be stored in one or more repositories. Prominence data may be collected automatically when the user views a page or clicks on a hyperlink without requiring separate action from the user to accomplish storage or retrieval. The prominence data may further include a display parameter that denotes a level of prominence that is usable to affect the display of a hyperlink. A prominence score used to determine the display parameter may be calculated by dividing a count of click-throughs by a count of page views of the page containing the hyperlink. Other score calculations may be used. User feedback may be incorporated into the score calculation and may be collected through a toolbar, popup window, or other feedback-collecting mechanism.

Launch vehicle systems and methods for landing and recovering a booster stage and/or other portions thereof on a platform at sea or on another body of water are disclosed. In one embodiment, a reusable space launch vehicle is launched from a coastal launch site in a trajectory over water. After booster engine cutoff and upper stage separation, the booster stage reenters the earth's atmosphere in a tail-first orientation. The booster engines are then restarted and the booster stage performs a vertical powered landing on the deck of a pre-positioned sea-going platform. In one embodiment, bidirectional aerodynamic control surfaces control the trajectory of the booster stage as it glides through the earth's atmosphere toward the sea-going platform. The sea-going platform can broadcast its real-time position to the booster stage so that the booster stage can compensate for errors in the position of the sea-going platform due to current drift and/or other factors. After landing, the sea-going platform can be towed by, e.g., a tug, or it can use its own propulsion system, to transport the booster stage back to the coastal launch site or other site for reconditioning and reuse. In another embodiment, the booster stage can be transferred to another vessel for transport. In still further embodiments, the booster can be refurbished while in transit from a sea-based or other landing site.
