Abstract

Although much work has been done on WWW information management, research in keeping information on websites up-to-date is still in its infancy. For a very large website whose content is derived from some source databases, it is important to maintain its freshness in response to changes to the base data. This issue is particularly significant for websites presenting fast changing information such as stock exchange information and product information. In this paper, we propose a model for studying the problem of refreshing a very large website in time. We identify several important research issues in maintaining the currency of information on such websites. We also discuss possible approaches to timely refresh a website under the framework.
