Abstract: System and method for modular sorting stations. A sorting station may be subdivided into two or more modular bins. A modular bin may be partitioned into compartments. Each compartment may be configured to receive one order including one or more items. Modular bins may be partitioned into compartments of different sizes to receive orders of different sizes. A modular bin may be removed from a sorting station and conveyed to a packing station for packing or other sorting station to continue sorting. Picked items may be received and sorted for rebinning into the modular bins manually or using an automated sorting mechanism. A control system may direct the sorting and rebinning operation. Modular sorting stations may be located adjacent to packing stations or, alternatively, away from packing stations and, when a modular bin is complete, it may be conveyed to an appropriate packing station for packing.

Abstract: Computer-implemented processes are disclosed for clustering items and improving the utility of item recommendations. One process involves applying a clustering algorithm to a user's collection of items. Information about the resulting clusters is then used to select items to use as recommendation sources. Another process involves displaying the clusters of items to the user via a collection management interface that enables the user to attach cluster-level metadata, such as by rating or tagging entire clusters of items. The resulting metadata may be used to improve the recommendations generated by a recommendation engine. Another process involves forming clusters of items in which a user has indicated a lack of interest, and using these clusters to filter the output of a recommendation engine. Yet another process involves applying a clustering algorithm to the output of a recommendation engine to arrange the recommended items into cluster-based categories for presentation to the user.

Abstract: One or more images of items for an order being processed at processing station of an order fulfillment center may be captured and associated with the order. Alternatively, a short video clip may be captured of the order being packaged. An electronic notification that the order has been processed may be sent to a customer associated with the order. The electronic notification may include a reference to one or more of the captured images or video clips. The customer may use a reference included in the notification to view the captured images. The customer may view captured images to verify that the order has been correctly processed. The captured images may include images of the items being packaged for shipment and may show the shipping address on the package allowing the customer to verify that indeed it is his package in the images.

Abstract: Method and apparatus for measuring true end-to-end latency for calls to Web services are described. In embodiments, a Web service client and a Web service provider may collaborate to collect timing/latency data for calls to the Web service. This data may be collected, stored, and analyzed by a latency measurement service to generate displays and/or reports on true end-to-end latency measurements for Web service calls. Embodiments may collect Internet/network infrastructure latency for Web service calls up to and including the “last mile” to the Web service client and the Web service processing time. Additionally, by analyzing latency data collected from a number of Web services clients and/or Web service providers, embodiments may provide a macro-level view into overall Internet performance. In one embodiment, the latency measurement service may be a Web service.

Abstract: Method and apparatus for repartitioning and replication of a searchable index in a searchable data service. The searchable data service may provide a searchable index to a backend data store. The searchable index may be repartitioned, and a partition may be moved to another storage node, to allow the searchable index to grow beyond the limits of a single storage device. Repartitioning may also be performed to provide load-balancing of write requests. Partitions may be replicated across two or more storage nodes to provide redundancy, data durability, data availability and load balancing of read requests among the storage nodes and/or across data centers. In one embodiment, a lazy replication mechanism may be used in the replication of partitions. In one embodiment, replication may be performed using an anti-entropy protocol to replicate a partition, and a gossip protocol to update the replicated partition.

A method may include detecting a request to access a given online content source, where the request is generated on behalf of a given user, where the given online content source is one of a number of online content sources included within an interest space, and where the interest space is identified dependent upon indications of user navigation activity among the online content sources. The method may further include displaying to the given user a representation of the interest space in response to detecting the request, where the representation includes respective indications of at least a subset of the content sources included within the interest space, and for a given content source within the subset, displaying to the given user respective indications of users on whose behalf a respective previously-generated request to access the given content source has been detected.

Abstract: Data mining systems and methods are disclosed for generating data that is helpful to users in selecting between items represented in an electronic data repository, such as an electronic catalog. One disclosed data mining method generates pairwise comparison data for particular pairs of items. The pairwise comparison data for a given item pair reveals the degree to which users who consider both items in the pair select one item over the other. The pairwise comparison data may be appropriately exposed to users of the electronic repository. For instance, in the context of an electronic catalog, an item detail page for item A may be supplemented with an indication that users who view both item A and item B select item B a specified percentage of the time. Another data mining method uses item viewing histories and item purchase histories of users in combination to identify pairs of items that are good candidates for being recommended in combination.

Abstract: The present invention is directed to a method and system for continuously displaying image pages of digital content which are available over a network. More specifically, the method and system enables a user to view image pages in a continuous manner while a limited number of image pages are being downloaded at a given time. Several image pages which are adjacent to the image page(s) the user is currently viewing may be stored in temporary memory. The image pages in the temporary memory are utilized so that, within the image pages, the user can move the displayed image pages up and down without experiencing any discontinuation. In order to ensure continuous display throughout the entire digital content, the next possible set of image pages is constantly determined and obtained to update the current set of image pages in the temporary memory.

Abstract: A system provides a user interface through which users can flexibly tag individual items represented in an electronic catalog with user-defined tags, such as text strings, and obtain recommendations that are specific to particular tags. The tags and tag-item assignments created by each user are stored persistently in association with the user, and may be kept private to the user or exposed to others. Once a user has assigned a tag to a number of items, the user (or another user in some embodiments) can request and obtain recommendations that are specific to this tag. These recommendations may be generated in real time by a recommendation service that identifies items that are collectively similar or related to the items associated with the tag.

Abstract: Techniques are described for providing automated functionality to assist a user in purchasing an item for a recipient. An automated system may track various information about a series of item purchases from one or more services through which items can be purchased, and use information about past item purchases to provide various automated functionality for users that want to purchase items for various recipients. Types of functionality provided by the system include assisting in preventing recipients from receiving inappropriate items by monitoring item gift purchases and item self-purchases and responding to user requests to determine whether a specified gift would be appropriate for a recipient. In addition to information about past item purchases (e.g., whether a recipient has already received a copy of an item), the system can also use other information when determining whether a purchase of an item for the recipient is appropriate.

Abstract: A method and system for scaling navigation path weights among online content sources. A method may include determining a first probability of users traversing a first navigation path from a first to a second online content source, dependent upon a ratio of traversals of the first navigation path and traversals of all navigation paths to the second online content source. The method may also include determining a second probability of users traversing navigation paths from the first online content source to any of the online content sources, dependent upon a ratio of the plurality of online content sources to which navigation paths from the first online content source exist and a total number of the plurality of online content sources. The method may further include generating from the probabilities a scaling factor indicative of a strength of the first navigation path relative to other navigation paths among the online content sources.

Abstract: A keymap service architecture for a distributed storage system. A system may implement storage nodes configured to store replicas of data objects, where each of the replicas is accessible via a respective locator value, and keymap instances each configured to store keymap entries corresponding respectively to the data objects. A given keymap entry may indicate a mapping from a given key value corresponding to a given data object to each respective locator value of its replicas. Each of the keymap instances may store a replica of the given keymap entry and may index its respective stored keymap entries within a respective index data structure including hierarchically arranged index nodes corresponding to keymap entries. For a given keymap entry having a given corresponding index node, each tag value associated with each ancestor of the given corresponding index node may be a prefix of the given key value.

Abstract: A transaction account verification system and method are provided. A user computing device transmits an account registration request that includes a selection of an account verification technique. A service provider obtains the request and initiates a set of transactions with an identified financial service provider. The service provider generates a verification token reflective of the set of transactions and at least one piece of information associated with the selected account verification technique. The user computing device generates a user verification token from user input regarding the set of transactions and at least one piece of information associated with the selected account verification technique. The service provider can verify the transaction account and set transaction thresholds based upon matching verification tokens.

Abstract: A method and system are provided for finding items for grouping items according to sorting characteristics. For example, a price comparison engine is described that obtains the original total purchase price for all items placed in the customer's shopping cart and compares the original total purchase price to further generated total purchase price options to determine if any cost savings can be achieved. Those further total purchase price options are generated by computing the total purchase price resulting from each possible combination of sellers and items in the shopping cart. In some embodiments, heuristics may be used by the price engine to reduce the number of seller combinations and purchase price options generated, limit the price variations upon which the total purchase price options are computed, and/or filter or sort the purchase price options to be displayed.
