Abstract: Verification of an inventory of stored products may be achieved by obtaining an image of the stored products and using text, optical character, and other feature recognition techniques to determine product identification and storage location. A comparison between earlier and current images of the same storage location is used to identify which locations have changed, i.e., from which locations have products been moved, removed, or added. The earlier and current images of the changed locations may be displayed to a user to visually inspect the differences between the images and verify the changes in inventory represented by those differences.

Abstract: A client component runs on a user computer in conjunction with a web browser and detects errors, such as but not limited to “404: page not found” errors, in which a requested web page or other object cannot be displayed. In response to detecting the error, the client component notifies an error processing server, which uses the URL of the failed request to identify an alternate object to display. The alternate object may, for example, be (a) an object retrieved from replacement URL, or from a URL that is otherwise related to the requested object, (b) a cached version of the requested object, (c) an object retrieved from a closely matching URL found in the user's clickstream history, or (d) a dynamically generated page that includes links to one or more of the foregoing types of alternate objects. Also disclosed are methods for identifying alternate objects for a given URL.

Abstract: An automated method and system for providing an item comparison includes identifying a first item and a set of one or more other items for comparison with the first item, prioritizing attributes of the first item and the other items, and providing the item comparison with prioritized attributes to a user. Identifying comparable items may involve a multiple step process in which a candidate set of items is first selected for possible comparison with the first item, and thereafter selecting one or more items from the candidate set for comparison. Prioritizing the attributes of the items may include measuring like attributes of the items against each other and arranging the attributes to appear in an order according to the degree the like attributes distinguish the items from each other. A modified item comparison may be prepared and provided in accordance with user feedback.
