One important step in integrating heteroge-neous databases is matching equivalent at-tributes: Determining which fields in two databases refer to the same data. The mean-ing of information may be embodied within a. database model, a conceptual schema, appli-cation programs, or data contents. Integra-tion involves extracting semantics, expressing them as metadata, and matching semantically equivalent data elements. We present a proce-dure using a classifier to categorize attributes according to t

Site maps are essential to assist users in navigating a Web site. Most of the site maps are constructed manually and are static. However, di erent users may have di erent preferences and purposes for using a Web site. For example, a user may want to see a more detailed map while another user prefers a more abstract map. Two users looking for di erent topics at a large portal site would bene t more from two site maps with di erent focuses than a single map. In this paper, we present a technique f

Wide-area database replication technologies and the availability of content delivery networks allow Web applications to be hosted and served from powerful data centers. This form of application support requires a complete Web application suite to be distributed along with the database replicas. A major advantage of this approach is that dynamic content is served from locations closer to users, leading into reduced network latency and fast response times. However, this is achieved at the expense
