Abstract: The systems and methods described herein enable measurement of the exposure of a user to advertising campaigns across different channels (e.g., websites accessed by web browsers of laptops, desktops, or mobile computers, electronic readers or tablets, applications on mobile devices, and the like) and credit the exposure of the user to the advertisement to a specific advertisement in the campaign along with subsequent shopping events generated by the user, such as visiting product detail pages, visiting the read all reviews page for a product, adding a product to a wish list, adding a product to a shopping cart, subscribing to a product through an online subscription service, and/or purchasing a product.

Abstract: An item categorization service is described that automatically categorizes items of interest to a user. The user may possess an item that they wish to offer for sale using a network-based service. The user may submit item information to the item categorization service to categorize the item of interest. Upon receipt, the categorization service may assess the relevance of the item information to hierarchically organized categories maintained by the network-based service. Categories having the highest relevance may be identified as first category candidates. The deepest common ancestor of the first category candidates may be identified the first category. One or more categories, representing sub-categories of the first category, may be identified as and subjected to relevance assessment. Those sub-categories having the highest relevance may be identified as second category candidates. The deepest common ancestor of the second category candidates may be identified as a second category for the item of interest.

Abstract: A method is described for selecting and caching a video advertisement to be presented on a client device. The method may include determining customer interests for an individual customer, selecting a video advertisement based upon the customer's interests and providing the video advertisement to a client device so that the video advertisement may be cached on the client device and may be available to display to a customer when a customer selects video content to play on the client device.

Abstract: Disclosed are various embodiments for item categorizer. The item categorizer is configured to parse, in at least one computing device, at least a plurality of product descriptions of a like item category for identifying a plurality of keywords with regard to the like item category. Furthermore, the item categorizer selects a plurality of subsets of keywords from the plurality of keywords, each subset of keywords comprises a unique combination of the plurality of keywords with respect to each other. Moreover, the item categorizer is configured to generate a respective rule for each corresponding subset of keywords, wherein an application of each respective rule specifies a respective binary result depending upon whether the corresponding subset of keywords is included in a seller product description.

Abstract: A method and system are disclosed for browsing an electronic hierarchical product catalog. The catalog is organized as a tree data structure with each node corresponding to an item category, an item sub-category, or an attribute that describes characteristics of items in a category. Such attributes may be used as filters for searching for an item or item category. The catalog tree is a collection of linked independent sub-trees including category and attribute sub-trees. The sub-trees allow navigation of the catalog tree via links between various nodes. The sub-trees may be linked to multiple other sub-trees, providing easy navigation for users and simplifying the addition of new sub-categories and attributes to the catalog tree, for service providers. The use of linked sub-trees also allows attributes set by the user in a previous search to be used in a subsequent search for a similar item.

Abstract: Disclosed are various embodiments providing an enhanced concept list for browsing within item search results. A pool of items is generated in a computing device in response to a search query. A plurality of relevant concepts is determined. The relevant concepts are those relevant to the search query. At least one network page is encoded for rendering by a client. The at least one network page includes a concept list and at least a portion of a plurality of items. The items in the plurality of items are responsive to the search query. The concept list corresponds to the plurality of relevant concepts. Each of the relevant concepts in the concept list operates to limit a view of the plurality of relevant items to items located in the respective relevant concept.

One or more categories related to the first category may also be identified and subjected to relevance assessment. Those related categories having the highest relevance may be identified as second category candidates. The deepest common ancestor of the second category candidates may be identified as a second category for the item of interest.

Abstract: A search can be refined to locate information about an item based on dynamically selected and ordered search categories. More specifically, methods and systems identify a set of search categories based on search category preference information obtained from the search results. The data entries are returned after searching on data stores with a search query provided by a user, and then the ranks of the returned data entries are determined based on a degree of relevancy with the search query. The dynamically selected search categories are displayed in an order corresponding to the rank of the data entries where the search category preference information is obtained.

Abstract: The present invention is directed to a method and system for refining a search to locate information about an item based on predetermined search categories. More specifically, the method and system dynamically display search categories based on relevancy information of a search result. A search category generally includes a set of category values which are used to filter the data entries into a subset of the search result. The data entries are returned after searching on data stores with a search query provided by a user and then the ranks of the returned data entries are determined based on a degree of relevancy with the search query. The data entries are displayed in order of the ranks and the set of category values for a search category are displayed to reflect the ranks of the data entries.
