In this paper, we describe an automatic imagegathering system from WWW, in which we use both keywords and image features. By exploiting some existing keyword-based search engines and selec...

In this paper we investigate issues related to building highly-available World Wide Web (WWW) servers on workstation clusters. We present a novel architecture that includes a dynamic Domain Name System (DNS) and a WWW server based on passive object replication. This architecture allows to reduce the service down-time of a WWW server without impacting on the Hyper Text Transfer Protocol (HTTP) p...
