Abstract
News editors obtained the following quote from the background information suppli ed by the inventors:“Delivering accurate, relevant and sometimes user-tailored data to users is often a challenging task for anyonline system, particularly on es with large databases. In some cases, a database may include various dataentr ies that are fast changing. The various changes in the databases may affect how a user interacts witha system. In some cases, a data entry may be associated wi th a real-world object that has a temporalnature. For example, in an inventory management system, an entry for an inventory item may be associatedwith timing information for an expiring item. Determining the nature of the real-world objec t is oftenchallenging for a conventional computing system. The failure to provi de accurate timing informationconcerning various real-world objects often adver sely affects the user experience of an online system.”
