Abstract: A return request processing engine automatically approves or denies requests for authorization to return a purchased item to the seller of the item. The return request processing engine utilizes return request rules to determine whether a particular return request can be approved or denied without input from the seller. When a request is received from a buyer to return an item, the return request processing engine utilizes the return request rules to determine if the request to return the item can be automatically approved or denied without input from the seller. If the return request processing engine cannot automatically approve or deny a return request, the return request processing engine causes a message to be transmitted to the seller of the item that provides a user interface through which the seller can indicate whether the return request is approved or denied by way of a single user input.

Abstract: This disclosure describes various processes for collecting information about users from sources other than catalog activity data. This information can be used to generate recommendations for users with activity data deficiencies. Some example sources for this supplemental data include collaborative content sites, such as social networking sites. Social networking sites typically allow users to engage in conversations with other users through text, audio, and/or video. Conversation data collected from these sites or from other sources can be analyzed to infer user interests. A recommendation process (or other application) can use the inferred interests to supplement or take the place of catalog activity data.

Abstract: Systems and methods for monitoring Web page content associated with processing a resource request are provided. A client computing device generates a sample image corresponding to a set of resources rendered in response to a resource request. A processing component, such as an image analysis component, then compares the sample image with an averaged reference image to identify a compared image. The averaged reference image is determined from averaging a pixel intensity value for each pixel in a first reference image with a pixel intensity value for each pixel in a second reference image. These first and second reference images both correspond to the same set of requested resources. The processing component then weights the compared image to produce a weighted compared image and determines whether a sum of the intensity values for each pixel in the weighted compared image exceeds a threshold. Aspects of systems and methods for generating an alert message if the threshold is exceeded are also provided.

Abstract: Control planes of virtual resource providers may be customized in a secure, stable and efficient manner with virtual control planes. Control planes may be modularized. Control plane modules may be supplied with data from standardized sensors, and required to generate standardized resource configuration requests responsive to solicitations with specified response latencies. Custom control plane modules may be selected to replace or complement default control plane modules. Financial and computational costs associated with control plane modules may be tracked. Competing resource configurations may be mediated by a control plane supervisor. Such mediation may be based on control plane module reputation scores. Reputation scores may be based on customer feedback ratings and/or measured performance with respect to module goals. Mediated configuration parameter values may be based on a combination of competing configuration parameter values weighted according to reputation.

Abstract: Disclosed are various embodiments for separating control of network sites through the use of a proxy server application. A proxy server application obtains a request for a network page associated with one customer out of several customers of an organization. Each of the customers has an online presence hosted in a trusted network. The trusted network is subject to security supervision by the same organization. It is determined whether the network page is within a customer-managed portion of the network site. The network page is obtained from an untrusted network that is not subject to security supervision by the organization when the network page is within the customer-managed portion of the network site.

Abstract: A facility for processing a request for information about a specified item is described. The facility receives the request from an originator. In response to receiving the request, the facility generates a response to the request that contains information about the specified item. The facility also determines a current level of availability of the specified item, and, based upon this determined level of availability, determines, for each of a number of ordering actions, whether the ordering action is currently available for the specified item. For each ordering action determined to be currently available for the specified item, the facility augments the generated response by adding a control for performing the ordering action. The facility sends the augmented response to the originator of the request.

Abstract: The top rated products in a product category are identified by computing a score for each product in the category. The score is computed by calculating a time decay factor for each product category. The time decay factor is utilized to decay the ratings of each product as a function of time. A relevance value is also computed for each product. The relevance value is utilized to modify the ratings for each product in view of the recency of the ratings. The score may be computed for each product using the ratings for the product, the computed time decay factor, and/or the relevance value. The computed scores are utilized to rank the products in the product category.

Abstract: Systems and methods for managing requesting routing functionality associated with resource requests for one or more resources associated with a content provider are provided. A content delivery network (“CDN”) service provider, on behalf of a content provider, can process domain name service (“DNS”) requests for resources by computing devices and resolve the DNS requests by the identification of a network address of a computing device that will provide the requested resources. Based on the processing of DNS queries initiated by a client computing device, the CDN service provider can measure CDN service provider latencies associated with the generation of DNS requests by network components associated with the client computing devices. Examples of the network components can include DNS resolvers associated with the client computing device.
