Abstract: Systems and methods for providing content are disclosed. In an embodiment, information encoding at least one keyword that is associated with first content accessed by a user is received. A search query based at least in part on at least one keyword is executed to identify items. In response to a request from the user to access second content, a response is generated to the request that includes item information associated with at least a subset of the identified items. The response is provided to the user.

Abstract: A collection of items may be categorized according to a category hierarchy. A search of the items may be explicitly associated with a particular category in the hierarchy or else unassociated. A set of refinements may be available, for example, to help narrow the search. Refinements may be applicable to items in linked categories. Refinements may be surfaced based at least in part on linked categories associated with the search. Refinements may be surfaced when the search is unassociated with a particular category. For example, a possibly relevant set of categories may be determined. Refinements may be surfaced according to a variety of ordering criteria.

Abstract: A method includes, in a server residing in a network of interconnected computers, receiving user data, dissecting the received user data into a plurality of key/value pairs, iterating through the plurality of key/value pairs, generating a new data structure in the memory of the server for each key/value pair that do not exist, inserting a UserID into a set associated for a specific key/value pair, storing the key/value sets, and destroying the received user data.

Abstract: Effective color-aware search of a collection of content associated with one or more images is enabled. Content and/or its associated images may be automatically associated with representative palette colors in a suite of color palettes. Color palettes may be of a variety of types and have a hierarchical structure in which lower levels enable increasingly subtle distinctions between shades of color. Color palette hierarchies may be effectively presented, and appropriate portions emphasized based on associated search result sets. Search result sets may be refined and/or reordered in accordance with color palette selections and/or representative confidences of color palette selections for items at least referenced therein.

Abstract: Disclosed are various embodiments providing navigational aids within item search results. A pool of items is generated in a computing resource in response to a search query and a search context. At least one network page is encoded for rendering by a client. The at least one network page includes a ranked list of at least a portion of the items. The ranked list includes a navigational aid when a relevance score associated with the navigational aid meets a threshold. The relevance score is computed relative to respective relevance scores associated with items in the ranked list. The navigational aid has at least a same prominence within the ranked list as an item.

Abstract: A method and system for attributing activity to a user includes sending a first request for content from a browser executing on a consumer device to a first content provider. The first content provider responds to the request by generating a browser identifier and sending the browser identifier along with the requested content to the browser. Next, the user browser sends a second request for content to a second content provider. The user shares personal identification information with the second content provider. The second content provider contacts an attribute server to retrieve attributes associated with the user and generates a temporary ID. The second content provider shares the attributes and the temporary ID with an analytics server. The second content provider also instructs the browser to share the browser ID and the temporary ID with a user profile server.

Abstract: Methods and apparatus, including computer program products, for optimization of yield for advertising inventory. A method includes, in a network of interconnected computers, sending a request for a file from a browser residing on a user system to a publisher server, receiving the requested file from the publisher server, the requested file including instructions for the browser to request a site file from a rules server, receiving the site file in the browser, the site file including rules for deciding whether an advertising impression is desired, rules for valuing the advertising impression, and browser executable code that applies and evaluates the rules, executing the browser executable code to evaluate the rules from the site file which determine if one or more signals should be attached to an advertisement request, and selecting an advertisement from a network ad server based on a signal received with the advertisement request from the browser.

Abstract: A cordless power tool battery pack including an onboard circuit configured to electronically communicate with an associated battery charging system. The onboard circuit communicates information relating to the batter pack to a microprocessor or the like within the battery charging system and charging of the battery pack is controlled based on such communication.

Abstract: A computerized system and techniques facilitate the monitoring and management of online behaviorally-targeted advertising. In certain embodiments, electronic notifications related to advertising practices of members of an online advertising ecosystem are presented to users based on the discovery of elements of online content aimed at delivering targeted advertising messages to viewers of the content.
